On April 20, 2021, Glenn Tobin received Arlington County’s Bill Thomas Park Volunteer Award for the year 2020. The award recognizes an individual or group whose efforts show ongoing dedication and tangible benefit to Arlington’s natural resources, parks, and public open spaces.

Glenn has been an ARMN member since 2016 and a Trail Maintainer with the Potomac Appalachian Trail Club (PATC) since 2015. For years, he removed invasive plants at Windy Run Park and the adjacent Potomac River waterfront in the George Washington Memorial Parkway. Because of his work alone and with other volunteers, significant natural areas are recovering and becoming more beautiful and biodiverse. In 2020, Glenn raised money and worked with the PATC and the National Park Service (NPS) to rebuild the stone stairway that connects the Windy Run park trail to the Potomac Heritage Trail along the river, improving access for many people. Then, inspired by the reemergence of diverse native flora at Windy Run and along the Potomac, Glenn began working with experts in ecology, botany, and natural resources to create the website, Natural Ecological Communities of Northern Virginia, which provides information about the local natural plant communities to help make better plant selections for ecological restoration purposes in Northern Virginia, Washington D.C., and close-in Maryland. As a result of Glenn’s leadership, ARMN is adopting natural plant communities as a framework for park restoration, in collaboration with local jurisdictions. This work will have lasting impact on restoration planning throughout the County and on selection of plant species for the County’s native plant nursery.

Some of Glenn’s other work includes helping lead Weed Warrior Training with the NPS, assisting in leadership for Park Stewards, and mentoring others who share deep passion for helping restore natural areas in Arlington County and beyond.

ARMN is selected for the Virginia Chapter of the Wildlife Society’s 2021 A. Willis Robertson Award

On January 29, 2021, ARMN was selected as the 2021 recipient of the A. Willis Robertson Award from the Virginia Chapter of The Wildlife Society for its work on public outreach and education related to deer management. The award honors a wildlife non-professional or group that has exercised outstanding conservation practices on their own land or have made significant contributions to conservation activities in the Commonwealth.

In the last few years, members of ARMN led by Bill Browning have spearheaded public education to alert the community to the effects of deer browsing and begin the process of addressing barriers to developing an effective and humane program to control deer population in Arlington County. (See armn.org blog piece, “White-tailed Deer and Forest Health in Northern Virginia” that addresses how deer impact our forests.) The team worked on deer browse surveys, major outreach events with the Virginia Native Plant Society, the Deer Advisory Council for Northern Virginia, Arlington’s Urban Forestry and Environmental Services departments, and in 2019, with regional experts from VA, MD, and DC to create a volunteer training and public presentation that has been delivered over 40 times in the past two years.

Bill (the 2018 winner of the Bill Thomas award) and the other volunteers have also addressed Arlington County Board members, School Board members, the County Manager, the Chair of the Department of Parks and Recreation, and the Acting Chief of Police. Bill also made presentations to Park and Recreation department employees and to several Arlington County civic commissions who have supported this message with letters to the County Board.

They also talked to civic/neighborhood associations, garden clubs, Extension Master Gardener volunteers, local TV and social media, and spoke at regional parks and conservancy, and hunting club meetings. This outreach has done much to bring the issue forward, engage stakeholders, and provide county decision-makers with sound, unbiased information for their consideration of a deer management plan.

ARMN is excited for this honor and opportunity to credit members like Glenn Tobin for their instrumental work to benefit our local natural environment.

Yellow-rumps: A Bird Watcher’s Delight in the Winter, Spring, and Fall

Text and photos by Ginger Hays (except as noted)

Photo of a yellow rumped warbler
Yellow-rumped “Myrtle” warbler.

Yellow-rumped warblers ((Setophaga coronateare a very abundant species of the Wood Warbler family—those small, often brightly colored birds that bird watchers go crazy about during spring and fall migration. Bird watchers affectionately call them “butter butts.” There are two primary subspecies of yellow-rumped warblers: the Myrtle warbler, and Audubon’s warbler. The Myrtle warblers are mostly in the eastern United States and Audubon warblers are mostly in the western part of the country.

I love bird watching and think it is a great entryway activity to get people more attached to and involved in protecting the natural world. I also like the meditative act of being alone in a park, yard, or garden and truly having to slow down to see and hear what is around me. I generally have a camera with me when I go out because it helps me record and remember what I have seen.

The yellow-rumped warblers are rewarding—and at times frustrating—for bird watchers. The rewarding part is that there are a lot of them in North America, so you are likely to see and learn how to identify them. They also often hang out in lower-level tree branches, so they are easier to see. But sometimes there will be such a large flock that everywhere you look, all the birds seem to be yellow-rumps. That’s when it can get a little bit frustrating (at least for me), if you are really hoping to see a variety of birds rather than this one species! 

I have met many lovely people on bird walks or hanging out at Monticello Park in Alexandria looking for spring warblers. But just a few weeks ago, I asked a fellow birder her thoughts about yellow-rumps. She said that she likes that they are warblers that you can see in the winter, and though they have more subdued colors in the fall and winter, it is nice because she can watch them more easily when the trees have lost their leaves. This is an interesting aspect to yellow-rumps. Though they do migrate, they don’t go as far south as most warblers, and many stay further north, sometimes as far north as Nova Scotia.

Yellow-rumps use a variety of ways to get their food. They are known to fly out from a branch to catch insects. They can forage on the ground for insects or berries or hang onto a tree trunk or branch. They eat berries from juniper, wax myrtle, Virginia creeper, dogwood, and poison ivy plants. And it is an interesting adaptation that they can digest the wax on juniper and wax myrtle berries. This adaptation enables them to remain further north than other warblers.

If you look at the range map on the eBird website, you will see that yellow-rumps are present in this area in spring, fall and winter. They only leave for the summer months when they breed in northern parts of the U.S. and in Canada.

So, how do you identify these interesting birds? Well, they do have yellow rumps!

They also may have yellow in three places: on the rump, a spot on the side breast, and—especially breeding males—a yellow spot on their crown. Females and fall warblers are more brown overall, while the breeding male has blue gray on their back and crown streaked with black, and a black mask. 

Myrtle warbles (Setophaga coronata coronate), are the eastern subspecies of the yellow-rumped warbler and they have white throats. These are the yellow-rumped warblers you are likely to see in this area.

There is also a western subspecies, Audubon’s warbler (Setophaga auduboni auduboni), that has a yellow throat, rather than the white throats of the Myrtle warbler. Both of these warblers have what is called a “broken eye ring,” which is white above the eye and white below, but it doesn’t make a full circle.

Photo of a warbler in a bush.
Audubon’s warbler. I took this photo while visiting my sister out in California.

And to make it interesting, there are other wood warblers with yellow rumps: The magnolia warbler (Setophaga magnolia), and Cape May warbler (Setophaga tigrine) have more yellow underparts and generally are not as brightly colored on the backside as the yellow-rump warbler. They all show up in the spring and fall. (Real warbler experts likely know the progression of when they show up. While I don’t, but it is possible that they could all be here at the same time.)

There is a great presentation about warblers, including the yellow-rump, by Bill Young on the Audubon Society for Northern Virginia website: https://www.audubonva.org/online-programs. He includes fabulous pictures of warblers, most of which he took at Monticello Park. 

Finally, I recommend a visit to the bird banding station that usually operates in the spring at Occoquan Bay National Wildlife Refuge. I took these two photos there. I was quite moved by the experience of releasing a bird after it was banded! 

As I mentioned, I love birding, and love how these little guys show how birding can be rewarding any time of year. It gives one a reason to be outside, to slow down and observe, and while one is focusing on the birds, one generally learns something about the plants and wildlife around them!  I hope you find, as I have, that they are a gift that keeps on giving!

Birds of A Feather: The Making of a Video on How to Identify Local Birds

by Joan Haffey (ARMN), with input from Charlie Haffey (helpful brother)

When the Covid-19 pandemic struck, the programming coordinator for a senior services center near me asked if I would do some “Bird Zooms” for isolated seniors. Their clients are often locked down in their apartments or worse, in their room, with few, if any, external contacts. The coordinator knew that I was a master naturalist and interested in birds, and we thought watching birds through a window and trying to identify them might be an entertaining activity that one could do alone, especially with a good app like the Cornell University Lab of Ornithology’s Merlin Bird ID.

The senior center had done an excellent job of orienting their clients to online conferencing and providing both tech and security support before and during various Zoom programs they offer. It also had a number of security features in place, such as only allowing the host to share materials on the screen. While using Zoom to walk through the most basic steps of the app was useful, there were still some challenges.

How could I make sure everyone could clearly see, via video conferencing, the basic steps in action on a smartphone app? And how could I simplify the demonstration so the host did not have to manage the meeting while cueing up relevant portions of excellent resources on Cornell’s website?

Enter my brother, Charlie, a retired science teacher who has made many an educational video in his day. I provided a script, and he made a “Quick Look” video:

It proved to be both easy to use and the highlight of the talk! We have both been surprised at the steady pace of people who view the video. We also decided to make it available to anyone who would like to use it for educational purposes. So, here are some suggestions for anyone who wants to pair this video with a talk about how best to use the app:

Where Are Some Places This Video Could Be Used?

  • Senior centers
  • Civic associations
  • Home or online school programs
  • Church groups
  • NextDoor groups
  • Video conferencing with isolated individuals

Evaluations of this Bird Zoom for seniors show that one of the favorite parts of the talk was the cooperation with my brother. In that spirit, I asked him for a few ideas for successful video-conferenced presentations.

What are the best preparations for a presentation like this on an online conferencing platform?

  • It helps to have one person manage the conferencing needs while the other presents. It can be difficult to do both at once, especially monitoring for questions and security breaches.
  • Only have open on the computer the files to be shared during the presentation. This minimizes confusion or the potential for shares of information not meant for the audience.
  • An alternative to having files open on your desktop is to prepare a slideshow that includes all the information you need. Then you only have to open one file.

Do you have any guidance on clearly presenting information via video conferencing platforms?

  • Follow an outline with minimal points
  • Stick to these points
  • Keep the presentation short
  • Minimize visual and verbal information
  • Personalize the presentation as appropriate to connect the audience better with the presenter

We hope this video helps widen the worlds of people who really appreciate birds, both now and in the future!

Flying Squirrels—They’re Still Here!

by Kasha Helget

A couple of years ago, I shared a story about a wonderful program that Long Branch Nature Center runs each year about our local flying squirrel population. Among other things, we learned that these are southern flying squirrels (Glaucomys volans), 8-10 inches long (including their tails), and weighing on average a couple of ounces. Also, there are about as many flying squirrels as there are gray squirrels in our area. We don’t usually see the flyers because they’re nocturnal and generally hang out in the higher canopy of mature trees. And flying squirrels do not actually “fly.” They glide using skin flaps (patagium) that connect their arms and bodies. They are crazy cute with their huge eyes and tiny bodies—almost like big-eyed children in a Margaret Keane painting.

I was totally intrigued with the flying squirrel nesting box that Long Branch staff attached to a tree along with a feeding platform for nuts and peanut butter. So, I convinced my handy husband, Michael, to build one, which he attached to a tree near our deck with a roof deck where we could place nuts. I ended the story with us waiting to see whether “if we built it, they would come.”

We had no luck that year. It was late February and too near the end of the winter season to encourage the little flyers to use the nest box or grab nuts from the roof deck.

Last season was a mixed bag. Shortly after Thanksgiving, we began setting out mixed nuts for the squirrels as soon as it was fully dark. We set up a night camera to check on visitors and learned a couple of things: a few flyers did visit, usually well into the night. But almost as often, raccoons stole the nuts before the squirrels got to them.

That’s when we realized that the flyers preferred peanuts to the harder shelled nuts. The very best discovery, however, was that they actually used the nest box for their young! There was traffic in and out of the entry holes, and peanut “hand-offs” to a parent flyer inside the box.

And then came the shocking incident. The advice we read online was to clean the nest box only in January or February—the only time the box would definitely be empty. So, Michael climbed a ladder to remove the box for cleaning last February, and two very surprised squirrels emerged, and an equally surprised Michael retreated, deciding that the box was probably clean enough. He did finally remove it early this April to make a small repair. It was not occupied but definitely needed cleaning of nesting materials and peanut shells. I guess the flyers didn’t read the online advice about vacating the box in February instead of April.

This winter has been another story. We again began setting out peanuts right after Thanksgiving, and it didn’t take long till our little flying squirrels started showing up and waiting for their nightly treat. It’s become very predictable that when it is fully dark there are up to four visitors either sitting on the roof deck waiting for their peanut delivery or running up and down the tree till we place the nuts out for them. The whole show is over within seconds. They are incredibly quick, usually grabbing a peanut and “flying” to the ground or running up the back of the tree with their treasure.

We plan to continue feeding our little guys peanuts well into the spring or as long as they’ll take them. It has become the best 10 second thrill for us each evening, and definitely worth pausing Netflix to enjoy.

ARMN: Getting to Know Paul Gibson

by Alison Sheahan

Paul Gibson has been a stalwart volunteer ever since joining the ARMN program in Spring 2013, especially in the areas of citizen science. I was able to interview him online and then finally got to meet him at the ARMN Annual Chapter meeting in December 2019. Here are some fascinating things I learned about Paul.

What are your favorite ARMN volunteer projects?

I really enjoy a variety of projects. I have been doing stream water quality monitoring since shortly after I became a Master Naturalist. I recently became a Master Identifier so I’m looking forward to taking my turn at identifying the critters that we find in the streams next year.

I find it fascinating to see the variety of macroinvertebrates that are in our streams, their variation by stream, and what that says about water quality in different parts of Arlington county. It’s also rewarding to talk with members of the public who pass by when we are out monitoring. Everyone is so curious about what we are doing and when they find out, they want to know more about water quality. I think that the public education that we do is a very important part of our role as master naturalists.

I also monitor bluebird nest boxes at Taylor Elementary School. This project provides a clear view of the perils and successes experienced by our feathered friends. It’s been heartwarming to see bluebirds, chickadees, and tree swallows go from nest-building to egg laying to hatching to raising chicks to fledging but there have also been stark examples of nest predation on eggs or chicks. For better or worse, it’s a front-row seat to the circle of life.

Another citizen science project in which I have participated for a number of years is the Chesapeake Bay Foundation’s Grasses for the Masses program. Members of the public propagate native underwater grass seeds in a grow-out system in their homes, schools, or businesses over the winter and then gather to plant the grasses in area rivers to bolster grass populations and help restore the Bay.

What has surprised you most about ARMN?

The speed at which the organization is growing. It is gratifying to see the numbers of new ARMN members who graduate out of the Basic Training program every year.

What do you like most about ARMN?

There is such a wide range of volunteer activities available that there’s really no reason not to participate. With my schedule, it’s hard to get to a lot of organized events but I can also participate at times of my choosing, depending on the project. Monitoring the bluebird boxes, for example, doesn’t need a rigid schedule, so I can fit in two or three visits a week during nesting season in a way that works for me. But there are also a lot of scheduled events to build in, which is great because it’s also nice to participate in projects with other ARMN members.

Tell us something about your life experience that has shaped your perspective on nature.

I grew up in Wisconsin, two blocks from Lake Michigan, and visited Lake Superior every summer when I was young. So, I was exposed to the variety of fish and birds in those areas at an early age. In northern Wisconsin, I remember marveling at the wild shorelines but also learning about the hazards of taconite discharges into Lake Superior from the iron mining range in Minnesota. These experiences taught me that nature and biodiversity were all around us but so were the threats to it introduced by humans. 

 What is your background?

Growing up in the upper Midwest, I was aware of and, in a way, just took for granted, that we lived among the remnants of age-old geologic forces. It wasn’t until I moved east for graduate school that I realized how unique that area is. (I received my undergraduate degree from the University of Wisconsin, Madison in Political Science and I have a Master’s in Information Management from Syracuse University.)  As I settled into the DC area, those experiences gave me the background to appreciate the rich biodiversity and geology of the Potomac River Valley and the Chesapeake Bay. Besides the ARMN programs, I have learned so much from courses in the Natural History Field Studies certificate program of the Audubon Naturalist Society.

 What would people find interesting about the non-ARMN parts of your life?

I train our dogs in the canine sport of “nosework.” It’s analogous to what law enforcement detection dogs do except it’s a sport for pets. Instead of looking for illegal substances, we look for target odors in organized competitions. But the skills of the dog and handler are the same. Along those lines, there are growing numbers of detector dogs that search for invasive species. So, one of my goals is to train our dogs to find invasive plants or insects, which is increasingly being done. It would be a natural intersection of two of my interests and hopefully be beneficial to conservation.

Tell us something unusual about yourself.

I have two wildlife cameras in our back yard. I am always amazed at the visitors we have. I’ve captured pictures of foxes, raccoons, deer, flying squirrels, and even a hummingbird that tried to pollinate the lens. But I’m still waiting for Wile E. Coyote to show up!

Outstanding Participation in the 2019 City Nature Challenge! What Are the Next Steps?

by Louis Harrell

Citizen science activities are an important way for individuals to contribute to scientific knowledge and for members of the public to increase their knowledge of local natural resources. Currently, the largest citizen science project that ARMN supports is the City Nature Challenge. Read about the results of this year’s challenge and the role that ARMN played in the success of our local area.

Cities around the world compete in the City Nature Challenge to see who can make the most observations of plants and animals using the iNaturalist app to record photos and information, find the most species, and engage the most people. The 2019 City Nature Challenge was held from April 26–29, 2019, and included 159 cities. Like last year, ARMN-sponsored events contributed significantly to the success of the event. In total, ARMN lead 25 events that were attended by 173 people. In the Greater Washington, DC area (which includes close-in Virginia and Maryland communities), 1,268 people made 29,996 observations and identified 2,258 species. Worldwide, Cape Town, South Africa had the most observations and species. Washington, DC was in fifth place worldwide with the number of observers, and 10th overall. See Capital Naturalist by Alonso Abugattas for more details about this year’s CNC, with the focus on activities in Arlington.

If you couldn’t participate in this year’s Challenge, there are still many opportunities to contribute!  To move an observation from a “casual” observation to “research grade” in iNaturalist, the observation needs to be validated by at least one other knowledgeable person. You can find these observations on iNaturalist and validate them yourself. For a few hints about how to identify observations efficiently, see https://www.inaturalist.org/posts/24425-keep-cranking-with-those-id-s and https://www.inaturalist.org/posts/24578-one-last-push-results-will-be-tallied-9am-monday.

The most observed species in our area were:  Mayapple, Virginia Creeper, Poison Ivy, Tulip Tree, Garlic Mustard, and Virginia Spring Beauty. Below are photos of these species taken by City Nature Challenge participants in our area.

ARMN Celebrates 10 Years Serving Community and Launches Facebook Page

by Kasha Helget

The Arlington Regional Master Naturalists have reached a major milestone and expands its public outreach to the community in new ways.

Ten Years of Service, Growth, and Outreach

The Arlington Regional Master Naturalists group just finished its 10th year as a Virginia Master Naturalist chapter, and over 70 members celebrated the milestone at the Annual Meeting in December.

President Marion Jordan welcomed all the members and supporters at the gathering. She also gave a special nod to the first class of 2008, with over half the graduates still as active members. Jordan then thanked the ten+ partners who have worked with ARMN over the years.

She highlighted ARMN’s past achievements, present efforts, and plans for future activities. This included an acknowledgment of the various projects on which members have donated thousands of hours during the decade.

Also, education and outreach programs (including public events and instructional programs, nature center support, work with children inside and outside of the classroom, and school gardens);

2014 Marie Butler Leven Preserve e-Mammal Survey. Photo courtesy of Toni Genberg.

Added to this are citizen science (such as stream water monitoring, bird counts, tree, plant, and insect surveys, and more recently, bioblitzes and other surveys that use internet-based iNaturalist, eBird, and GPS tools to track plant, animals, and restoration efforts).

For the future, Jordan stressed the priority of expanding ARMN’s outreach to include more members of the community with events such as “pop-up parks” (to provide nature mini-presentations to passers-by both in parks and elsewhere), as well as more structured outreach to a variety of organizations and citizens.

The ARMN members also submitted their own reflections on their past and present involvements in the organization, and how they looked forward to continued participation during the next decade.

Active membership in ARMN has grown to over 175 individuals whose contributions have multiplied throughout the years. Just in 2018, members reported over 15,000 hours of work in support of the natural environment locally and throughout Virginia!

The ARMN organization has also been honored during its ten years by awards from the National Park Service and Arlington County, and individual members have been honored for their efforts in supporting Arlington’s natural environment.

ARMN Adds Facebook to its Outreach

ARMN has recently launched the Arlington Regional Master Naturalists Facebook page to engage members of the general public about local natural events, photos, discussion topics, or other items of interest in our natural world. Anyone can join by applying for inclusion in the group. We hope to see YOU participate there, too!

2018 Arlington BioBlitz is September 15th!

Arlington will be conducting its second Bioblitz, and this year it will take place at only one site: Glencarlyn Park. This is a wonderful opportunity for individuals to participate in a valuable citizen science inventory of plants, wildlife, and other living organisms in the community.

What is a BioBlitz?

It is a (usually) 24-hour survey to find and identify as many species as possible in a specific area. The information collected will help the County to update its Natural Resources Management Plan. Last year’s BioBlitz was a wonderful success. (See event summary at: 2017 armn.org blog.) This year the team decided to conduct surveys in only one park instead of several throughout the county.

Why would you want to participate in the BioBlitz?

Because it is a great way to find and learn about the wildlife, plants and other living things in Arlington. Participants will be teamed with experts to help find, identify, and catalog what they find, using a free application called iNaturalist. While you do not need any experience to partake in the event, individuals with expertise in plants, wildlife, or other living organisms are encouraged to participate.

ARMN: Getting to Know Yolanda Villacampa

Photos courtesy of Yolanda Villacampa unless otherwise noted.

ARMN’s Membership Committee occasionally posts profiles of our members, including how they came to be master naturalists, which parts of nature they most enjoy, and how they affect their environment. This latest biography features ARMN Member Yolanda Villacampa, who graduated from our training class in Spring 2011. She’s made quite a contribution to science as a naturalist. Read the blog through to the “something unusual about yourself” section to see for yourself.

 If you know someone in ARMN with an interesting story to tell and think others might be interested, please contact Bill Browning (browningwh@gmail.com) or Alison Sheahan (ab.sheahan@verizon.net).

Tell us about the ARMN projects you spend time on.

During my ARMN training class (Spring 2011), we had the opportunity to think about the type of volunteer projects we could choose from. Volunteering in Arlington County streams was a natural choice for me. Four Mile Run is practically right behind the house where I grew up in Arlington, VA. As a child, I had always enjoyed being near this stream, which is accessible via the backyard. I took walks with my mother and sister along the banks and biked along it with my father. I enjoyed looking inside the water to see the fish, snails, and rocks. So, I became a macroinvertebrate stream monitor under a program coordinated by the County’s Office of Sustainability and Environmental Management. As a macroinvertebrate volunteer, I can continue to check out what’s in the water and know that I’m looking at a black fly larva, isopod, left-handed lunged snail, or planarian.

I also have enjoyed documenting local wildlife by participating in wildlife mapping and citizen science projects. More recently, I have started using a newer way of observing wildlife with the iNaturalist app and have taken part in local bioblitzes. I can check out wildlife, photograph it, identify or find out what it is—whether it’s a dragonfly nymph or a great blue heron!

Other fun activities I’ve participated in include the cricket crawl in the summer, the frog/salamander patrol, bird outings, and outreach events.

How did you learn about ARMN?

I’m an Arlington County park naturalist on a part-time basis and heard about it at work. A fellow park naturalist at Long Branch Nature Center, Matt Neff, also an ARMN volunteer and animal keeper at the Smithsonian National Zoo, recommended ARMN. It sounded like a great way to keep learning about local nature!

What do you like most about ARMN?

The variety of volunteer opportunities for a wide area of interests in nature with terrific people taking part in it. It’s great to be outdoors and share information too!

Tell us something about your childhood/adulthood experiences that shaped your perspective on nature?

I grew up with woods and Four Mile Run stream behind my childhood home. I was fascinated by the wildlife passing through my backyard—a variety of birds, box turtles, opossums, caterpillars, walking sticks, praying mantids, and even the colorful box elder bugs.

Walks with my mom and sister near the stream towards Barcroft Park were a common ritual. Not too long after teaching us how to ride bikes, my dad would take my sister and me on biking excursions on the Four Mile Run and W&OD trails. A lot of my local vacations involved my father taking the family to state parks. We stayed in a cabin or went camping. I always remember the kind park ranger who that talked to me at Douthat State Park after a nature program.

At Claremont Elementary, we had a rabbit in school that roamed the classroom which I thought was the neatest thing. Pet rabbits were my favorite pets growing up.

When I was at Wakefield High School, I took an animal science class at the Career Center where I learned about and took care of classroom animals including snakes, a rabbit, ducks, and a chinchilla. I even had a summer job there taking care of the animals.

As a kid I have fond memories of my parents taking my sister and me to the National Zoo and the bus ride with my mom to Washington, DC to visit the Natural History Museum.

What is your background? 

During high school and college, I had seasonal jobs such as being a veterinary assistant and an outdoor job working as an Arlington County Park Ranger on bike. I have a bachelor’s degree in Biology from George Mason University in Fairfax, VA. After getting my degree, I started working a few hours at the Arlington County Nature Centers…and still do!

Currently in my full-time job as a Museum Specialist in Zoology, I work on invertebrates, such as mollusks, in the District of Columbia at the Smithsonian’s National Museum of Natural History—back to one of my childhood excursion locations!

Heritage-wise, my father was born in Spain and my mother in Ecuador, so I grew up speaking both Spanish and English. Thanks to my father, I’ve traveled to both countries and have enjoyed the adventures of traveling to various places. I’ve been able to put my Spanish-speaking and writing skills to use, whether helping Spanish-speaking visiting scientists and translating text at the Museum or conducting bilingual nature programs in Arlington.

Tell us something unusual about yourself.

I’m a District of Columbia/Arlington area native. At least it seems unusual to others when I mention it. As my mom likes to say, I was 18 months old when my family moved to Arlington from DC, where I was born.

A snail is named after me. In my first Museum Technician job after college, I helped with a research project to describe western US spring snails. Pyrgulopsis villacampae in Little Warm Springs, Nye County, Nevada is named after me.

The Importance of Citizen Scientists: Using iNaturalist to Create an Inventory of Natural Resources

By Louis Harrell

The recent City Nature Challenge, held 27-30 April 2018, exemplifies the important role that the general public plays by providing professional scientists with valuable data on biodiversity. Anyone can become a “citizen scientist” by going out and collecting data related to the natural world – made even easier today with the iNaturalist app. All you need to get started is a computer or a mobile smart phone and a desire to enjoy the great outdoors!

How does it work? The free iNaturalist app maps observations by different levels of geography, taxonomy, and type of observation. It can record and show all of the observations collected around the world, in the Washington DC area, or only those observations in a specific neighborhood. The 2018 City Nature Challenge provides an interesting and current source of data that can be used to demonstrate the power of the mapping capability of iNaturalist. Over 10,000 research-grade observations were collected providing insight into the distribution of natural resources in the D.C. metropolitan area. Research-grade observations are defined as identifications that have been confirmed by a second reviewer. Thanks to the capability of the app and the crowd-sourced second level review, citizen scientists can have fun collecting data and making material contributions toward understanding our environment.

Why would citizen scientists want to collect observations of various living things and map them? Collections of observations or inventories are a widely recognized technique used to identify long-term trends in biodiversity, the incidence of invasive plants, and the locations of other ecologically important species. For example, the data collected through iNaturalist allows a citizen scientist to document exactly when that garlic mustard appeared in the corner of a yard and if observations are collected over time, one can then observe the progression of the plant’s life. Since all data is collected with a standard method via iNaturalist, research-grade observations can automatically be integrated into larger files.

Inventories can be improved through well-known survey methodologies. The Fish and Wildlife Service (FWS) has published information that shows how sampling, careful data collection protocols, and appropriate collection technology can influence the quality of information and its utility for research, affect distribution of resources used to manage lands, and improve public understanding of natural resources. While the FWS document focuses on invasive species, its guidelines for research can be used for documenting any species in an area. For those interested in learning more, the FWS training can be found at: https://www.fws.gov/invasives/staffTrainingModule/assessing/inventory.html.

Citizen scientists of all ages can implement another inventory technique, the “Biocube,” which facilitates study of a very small space. The Smithsonian Institution developed Biocubes, which are hollow one foot cubic frames, that can be placed almost anywhere to show differences among living communities from different continents, different habitats, and wild versus domesticated land. The Smithsonian has published procedures to measure species diversity in a cubic foot. The method has been successfully used in marine and land environments and uses iNaturalist for reporting results. The strength of the approach comes from its use of a standard cubic foot sample size allowing comparison of results. The Smithsonian has published an introduction to Biocubes and a video that shows the history and significance of the technique at: http://ocean.si.edu/ocean-news/biocubes-life-one-cubic-foot.

How would a citizen scientist create a neighborhood data map?  The iNaturalist app is simple to use on a computer or a mobile phone. First, select the “Observations” option on the home page of the iNaturalist app, and then click “Explore.” This will display a map of the world. Next, click the filter button located in the upper right corner. Enter the desired options and the app will produce the specified neighborhood map. The example below shows how easy it is to display all research-grade observations from the City Nature Challenge:
