Hone Your  Observation Skills &

Improve Your Ability to Identify Ferns

On July 25 , 2026, from 10:00  am to 12:00 pm, Nathan Lambstrom will lead a walk down the Ben Utter Trail in Arcadia, Exeter, RI.  The focus is on taking the guesswork out of fern identification for the nature lover with no formal botanical training. Nathan will have some copies of Northeast Ferns that will walk us through a simple but precise logical key system. Bring your own copy if you have one.

Nathan Lambstrom is a lecturer in the College of Environment and Life Sciences (CELS) at URI. A garden ecologist, Nathan also runs his own business designing and planting gardens that support wildlife, conserve water, and enrich home environments. Nathan holds a MS in plant biology and conservation from Northwestern University.

We will walk for approximately 3 miles on an easy to moderate trail.

This walk is free and open to the public.
