Calling Citizen Science Volunteers – Urban Heat Island Mapping Project, July 8-24

Logo: FACS and GM Urban Heat Island Mapping Project

The Faith Alliance for Climate Solutions (FACS) and GMU are jointly coordinating an Urban Heat Island Mapping project and need citizen science Volunteering support.
This initiative will map temperature variations in the Fairfax County, Arlington, and the City of Alexandria area. Extreme heat is the leading cause of weather-related mortality in the United States and can vary dramatically depending on many factors like tree density.
Citizen scientists will collect data using temperature and humidity sensors along provided routes on “Measurement Day” – which will occur in mid to late July when summer temperatures are historically at their hottest.
Sign up as a driver (need a car), a rider (to monitor the temperature sensor), or as a 2–3-person team to handle both. There are 3 time slots during the day; you can volunteer for all 3 (preferred) or just one, and you can select the area you’d like to monitor. FMN Students can receive service hours and training will be provided.

Volunteer Expectations:

  • Watch the recorded volunteer training before your assigned shift(s).
  • Each team is responsible for picking up a sensor and measurement equipment from a designated pickup location prior to the Measurement Day. Flexible pickup arrangements may be available if needed.
  • Drivers and Riders should coordinate with their team prior to Measurement Day to figure out transportation and logistics. Arrive on time and be prepared to complete your assigned route.

Citizen Science Project – Caterpillars Count!

Photo credit: Don Coram, Sawfly larvae observed during CaterpillarCounts!

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,

Unintended Consequences

Many of our Fairfax County parks, NoVA Parks, and even our local state park (Mason Neck) have active Trail Steward Programs. They vary in responsibilities from physical trail maintenance to passive monitoring and reporting on trail conditions and nature interpretation for park visitors.

Trail Stewardship is one way to provide a greatly valued service to your favorite park. Our parks appreciate the efforts of their volunteers and most parks REALLY appreciate VMN/FMN volunteers because they have gone through training in conservation of natural resources and they tend to have a genuine passion for nature.

FMNs interested in Trail Steward or Trail Monitoring programs in the Fairfax County Park system can simply call your local park or search the Volunteer Fairfax opportunities site. For NoVA Parks, there are a few existing programs and you may contact Rachel Doody, Park Manager Potomac Overlook Regional Park & Winkler Botanical Preserve – rdoody@nvrpa.org for more details. For Mason Neck, please call the park and ask for the Volunteer Coordinator. A few stalwart FMN even volunteer as trail crews on segments of the Appalachian Trail via the Appalachian Trail Club. And yes, FMN has service codes for each opportunity.

So you may be wondering why this article is titled, Unintented

Consequences? Primarily, because I find that for every intentional action taken  volunteering with nature projects there are potential unintentional consequences that manifest by developing a deeper appreciation of  a specific “place”. Volunteering at one or two parks on a consistent basis, experiencing seasonal change, immersed in multiple ecosystems, the volunteer learns the phenological cycles of the park – the heart beat. For example, Fall reveals the glorious pallet of natural colors, and up sprout fungi – nature’s decomposer. The pulse slows.

Winter bares the bones of the forest and marks a period of rest for much of the flora and fauna. Reserving energy, blood flow slows to sustain itself through the cold. Spring ushers in an explosion of  new life to wetlands, meadows, and forests showing us ephemeral plants, the migratory patterns of birds, micro-fauna, and the treasures found in vernal pools. The pulse quickens.

Summer displays lush growth and the ability of nature to flourish through heat and harsh environmental events. The beat is strong.

I am fortunate, and at times blessed, to participate in various Stewardship and Educational programs at Mason Neck and, admittedly my favorite park, Huntley Meadows. Each park offers beauty, serenity, solitude, and an inner satisfaction that reaches new heights of appreciation as more time is spent understanding the heart beat of each.

Mason Neck offers Trail Steward programs that include clearing trails and reporting large trail obstructions to park staff in addition to the more casual Trail Monitoring.

Huntley Meadows offers Trail Monitoring, designed more as an interpretative trail service for visitors. We count visitors, report trail conditions, answer ad hoc visitor questions, and provide interpretation of nature within the park. Huntley is a unique FCPA park, in that it has three ecosystems – hardwood deciduous forest, meadows, and a non-tidal, hemi-marsh wetland. The boardwalk snakes its way around and through the wetland with additional trails that lead through the forest and around the meadows.

Being there on average six or seven times a month all year long provides such insight into the various macro- and micro-cycles of a living park land.

For example, my most recent trail monitoring report to the park included visitor engagement and general observations:

Miscellaneous Discussions

  • General discussion on the resurrection of a fallen owl’s nest (replaced by WRL with a cool basket) and the rescue of two owlets.
  • Frog discussion with a group inquiring about different species at HMP
  • Eagle vs Osprey discussion – aerial conflict, nesting, feeding at HMP
  • New beaver dam in barnyard creek watershed – new family in town??
  • Consistency of otter scat on the boardwalk (they eat freshwater mussels and clams, so shell fragments our found mixed in).

Daily Observations:
Air still; sunny; warm; 81°

Birds: Downey wood peckers; mallards; wood ducks; ravens; Canada geese; great horned owlet on nest; black vultures; pileated WP; red shouldered hawk; Cooper’s hawk; Osprey; Bald Eagle
Mammals: muskrats
Arthropods: blue azure butterflies on trail; damselflies; giant centipede
Herps: snappers; painted turtles; several species of frogs; spotted turtle; black rat snake; northern water snake
Fish – spawning carp
Plants: aquatic grasses, cattails emerging; spring beauties have sprung; Sweet Cicely; May apple in flower; cinnamon ferns unrolling; dogwood.

What is the adage we all learned in our VMN cohorts?
Awareness leads to knowledge, knowledge leads to understanding, understanding leads to appreciation, and appreciation leads to conservation.” 

Give Stewardship a try. Reap the rewards of unintended consequences.

Service Opportunity – Meadowlark Botanical Gardens

The Natives Team at Meadowlark Botanical Gardens, which includes several Fairfax Master Naturalists, has gotten off to a great start this spring, in spite of the crazy up-and-down weather.  Projects we have worked on include:
1.  Transplanting into pots native seedlings that were grown from seeds collected last year in the gardens.  We will be transplanting the seedlings into the ground later this year.

Photos Meadowlark Botanical Gardens-transplanting

2.  Creating a new trail that will connect existing native areas and allow for managing invasives in the surrounding woods.

Photos Meadowlark Botanical Gardens-trails

3.  Planting American chestnut trees, sourced through the Virginia Department of Forestry’s chestnut research and reintroduction program, which is cross-breeding chestnut trees for blight resistance in the hopes of bringing back a species that once dominated the forests of eastern North America.

Photos Meadowlark Botanical Gardens-planting

Several other projects are in the works, and we could use some help!  Most of the team usually volunteers on Tuesday mornings, but volunteers would also be welcome on other weekday mornings.  If you would like to join us, please reach out to Meadowlark’s volunteer coordinator, Emma Werthmann at
ewerthmann@nvrpa.org and tell her you are interested in the Natives Team.
