Greetings Master Naturalists and Biodiversity Enthusiasts!

Volunteers for this Cit Science activity can record hours under:  C254: Caterpillars Count! — National Science Foundation

In 2025 several FMN volunteers contributed 85 hours to this code.Please read below for registration details. Volunteers will use INaturalist as the field tool.
Thank you.

You are invited to learn more about the citizen science project Caterpillars Count!, which aims to better understand:
•        insect declines (and hence bird declines)
•        shifts in seasonal insect activity
•        impacts of climate change and urbanization
•        importance of insect-host plant relationships.

Participants conduct surveys on the branches of trees and shrubs to monitor seasonal variation and abundance of arthropods like caterpillars, beetles, and spiders, and to establish critical baseline data for evaluating long term trends. To date, 2,500 participants have conducted 140K surveys across 37 states and provinces in North America.

The project can be easily carried out ANYWHERE IN THE WORLD with woody vegetation, especially:

•        Nature and environmental education centers
•        Parks and botanical gardens
•        School campuses (used at 14 colleges and universities)
•        Private backyards

The Maps and Graphs page allows anyone to fully explore the dataset, and the team has published a variety of  lesson plans and learning activities surrounding both data collection and analysis.

For more details on the project and what hosting a survey site for Caterpillars Count!entails, watch the short video on our project website, and check out the Frequently Asked Questions page.

In the meantime, do not hesitate to contact the team to answer any questions.  You can reach the team by emailing caterpillarscount@gmail.com.

And, please, forward this email along to any friends, colleagues or local groups you think may be interested in monitoring the biodiversity around them.

Best wishes,

The U.S. Geological Survey maintains several monitoring stations in Reston’s streams.  Join scientists Brendan Foster and Joao Gallotti on a walk along Snakeden Branch.  Discover the importance of stream quality monitoring for safeguarding public health, sustaining aquatic ecosystems and informing water resource management decisions.  The walk will begin at the Walker Nature Center (11450 Glade Drive in Reston) and will involve hiking over uneven terrain.  Register by June 1.

The Rocks Beneath Our Feet

Saturday, June 13, 2026

Walker Nature Center educational programs are eligible for FMN CEUs.
If you are familiar with the reston.org WebTrac system, you can register there.  Otherwise, you can contact the Walker Nature Center directly at naturecenter@reston.org or 703-476-9689.  Note the registration deadline for each program above.

Sunday, May 17, 2026 or Sunday June 7, 2026
10:30am-12:30pm

Registration is required:  Click this link for registration information

There is room for 20-25 people to join  on these walks. 

Join Alan Ford, President of the Potowmack Chapter of the Virginia Native Plant Society, for a nature walk in the beautiful woods and creek area of the Amberleigh HOA.  The walks are scheduled for Sunday, May 17 at 10:30 AM or on Sunday, June 7, at 10:30AM. Join participants for a walk adjacent to an acidic seepage swamp, recognized as a globally rare ecosystem. The walk will take place on the property of the Amberleigh HOA in Alexandria (Fairfax Co), the site of a portion of the planned Cinder Bed Road Bikeway. The walk will highlight the plant communities that live in this threatened ecosystem. This is a unique opportunity to view a healthy ecosystem that is under serious threat within a year or two if the bikeway is constructed.

That’s right! If you live in Amberleigh, those woods behind your homes are owned by your HOA and the area is known as the Newington Conservation Site. Learn about the unique habitat of this area, the plants and animals live there, where water comes from and goes.
