In mid-May I joined a group of citizen scientists  gathered at The Clifton Institute (Clifton) in Warrenton, Virginia, equipped with a radio receiver and antenna.  As the faint pings from the receiver grew louder, we followed the direction of the strongest sounds and eventually found our prize, a Woodland Box Turtle (terrapene carolina carolina)!  The transmitter equipped creature was snuggled in tall grass and would have been difficult to find without the transmitter.

We began our day learning about Clifton’s ongoing Box Turtle research program from Andrew Eberly, Habitat Specialist and our guide for the day.  Clifton is unusual in being not just an education center but also a research station and a conservation organization. That means that participants on their field trips have the unique opportunity to participate in real scientific research and to see ongoing restoration projects in action.

In spring 2022 Clifton launched an exciting new research project on Box Turtles. The goals of the project are to better understand how Box Turtles are doing at Clifton (where they are still common), why they are declining in the region, and how landowners can help turtles. They are especially interested in studying the animals’ movements in different kinds of habitats so that they can advise landowners on when and how to change mowing and haying practices to minimize turtle mortality.

When they find a turtle they notch its shell with a unique code so that they can identify it when they (hopefully) see it again. They have found more than 106 turtles! They estimate that roughly 370 turtles live on the 400 acres they have surveyed. They have been amazed to find so many and want to figure out what makes their property so turtle-friendly.

As a pilot study, they attached radio transmitters to five of the turtles and tracked their movements to get a better idea of where they’re hanging out and when. Five turtles didn’t tell them much, but the tracking worked well enough that they had expanded to twenty turtles by the time of the May field trip.

After some of us took turns using the receiver and antennae to locate some of the previously

identified turtles, we moved to “Turtle Junction”, a site on the property known for its turtle habitat.  We were delighted to find two more unmarked turtles there.  Andrew carefully notched their shells, and weighed and measured them to log them into the survey subjects.

Flush with success, the group moved out of the lush forested area just as a spring downpour began.  Although The Clifton Institute is a 45-minute drive away from my home, the trip provided enough education, outdoor time in beautiful surroundings, and the feeling that I had added needed information to citizen science that I would readily go again and highly encourage you to do the same!

 

 

Beginner Lichen Identification Workshop, December 17th

Register here.

Lichens: part algae, part fungi, all mystery! Did you know that we have more than 400 species of lichens in our region and that many of them can be identified with a little practice and a hand lens? Lichens in our area are diverse in their appearance, in where they grow, and in how they reproduce. The northern Piedmont is a great place to learn lichens because we have a fascinating blend of mountain and coastal plain species. The 900-acre Clifton Institute hosts at least 75 species, including some mature forest specialists like the Shaggy Fringe Lichen.

In this program, lichenologist and mycology teacher at George Mason UN Dr. Natalie Howe will teach us the basics of lichen biology and then lead us on a walk around the field station to see how many species we can find. No experience with lichens is necessary.

Join the Clifton Institute for the second annual Dragonfly Count! The goals are to learn which species of dragonflies and damselflies are found in the area, to monitor changes in their populations, and to encourage everyone to learn more about Odonates!

Dragonflies and damselflies are some of the most mysterious and beautiful animals that live at the Clifton Institute, and June is the perfect time to search for them. Workshop attendees will visit lakes, streams, and fish-free vernal pools, each of which host distinct dragonfly communities. The time period, 11AM-1PM, was chosen because it will be late enough in the day that there will be dragonflies flying but it’s not the absolutely hottest part of the day. Attendees are welcome to bring a lunch and eat on Institute’s picnic tables after the program.

During this workshop and volunteer day, join Alison Zak, M.A., founder of the Human-Beaver Coexistence Fund, to learn about the importance of coexisting with beavers and how to protect trees from being chewed down. After a brief talk, volunteers will get hands-on experience wrapping trees using HBCF’s recommended methods.

The Clifton Institute is starting a research project to study box turtles. They want to know what habitats they use, what time of year they’re most active, how big their territories are and how much overlap neighboring territories have, and most importantly what can be done to help conserve this long-lived species. To start, they need to have a better idea of how many box turtles there are on their property and where they can find them.  The Clifton Institute needs your help! In late May or early June, they are going to wait for rainy weather and spend a day walking all of the trails looking for box turtles. They will divide registrants into teams to cover more ground. The more eyes the better! No experience is needed. Volunteers will be walking on uneven and potentially steep trails.

They chose May 18 as the date they expect to be the earliest possible survey date, but they will wait for the right weather and email registrants with more information.

 

Warbler Song Bootcamp: Hybrid webinar, April 15th

/in , /by

Friday, April 15, 2022
6 – 7 pm
Register here for either in person or online.

Brush up on your warbler songs just before the migrants arrive in droves. Sponsored by The Clifton Institute, they will listen to the songs of each of the migratory warblers that pass through our region in spring, while looking at spectrograms to help visual learners identify differences in similar songs. They will also briefly discuss habitats where breeding warblers can be found in our area and cover a handful of other migrants such as vireos and thrushes.

This workshop will be of interest to birdwatchers of all skill levels. It will definitely be more fun than listening to a warbler song CD in your car! This program will be a hybrid in-person / virtual event. They think it’s more fun to get together in-person and learn from each others’ birdwatching experience, but also want to make this class accessible to people who don’t live within driving distance of the Clifton Institute. Please indicate which way you plan to attend below by RSVP’ing. If you RSVP to the “Virtual (Online) Only”, you will be sent a Zoom link a few days prior to the event.

Invasive plant species crowd out native plants and provide little to no food for native animals. Every winter Clifton Institute works to remove invasive Autumn Olive from around their property and over the last few years they have made a lot of progress, thanks to all of their amazing volunteers! Join them on October 23 to start the 2021-2022 Autumn Olive removal season.

Registration is REQUIRED so that they can communicate with you in case of changes.

Introduction to Statistics Virtual Program (Presented live December 3rd)

/in , , /by

Presented and recorded by Clifton Institute

This talk is intended for community/citizen scientists who help collect data but may not have the knowledge they need to analyze it, for nature journalers who record numbers in their journals but aren’t sure what to do with them, and anyone else who is curious about how scientists use data to understand the world. Managing Director Eleanor Harris, Ph.D., will give a brief introduction to the statistical methods biologists and other scientists use to analyze data. Eleanor will use interesting examples relevant to the ecology of northern Virginia throughout the talk. No mathematics beyond high-school level will be required. By the end of the talk you’ll understand what a p-value is and what it means when they say the phrase “statistically significant” on the news. And she hopes you’ll be inspired to try analyzing some data of your own.

Here is the recording of the talk.
