Biothon 2018: The Annual Search for Species

Help raise funds for environmental education!

The Hitchcock Center’s 19th annual Biothon is a fun team event during peak spring biodiversity, getting us outside to explore and count local species.

This year, our 19th, we dedicate Biothon in memory of Elizabeth Farnsworth, former Board member and Biothon organizer, renowned biologist, educator, and illustrator.

Biothon Instructions

Biothon happens during the weekends of Friday, May 11 – Sunday, May 13 and Friday, June 1 – Sunday, June 3.

People form teams, and head out to a favorite natural area where lots of species can be found (birds, plants, mammals, etc.) — birders tend to go out in May, and those looking for plants tends to have better results in June.  The choice is yours!

You choose what date and time to go out, and in what location(s). Zoos don’t count!

To raise funds, teams reach out to their colleagues, friends, family and supporters to collect gifts and pledges in support of their outing.

We have some sample language you can use in an email to help get you started. Read more about how Biothon works here.
