Glance at a vernal pool in October and you’ll see a dull, dry depression in the forest floor. Look again in spring and you’ll find a woodland pond, teeming with life. Dig in to the exquisite, ephemeral world of vernal pool ecology in this afternoon workshop with Brett Amy Thelen. We’ll start indoors with an illustrated lecture, then venture outside for hands-on exploration of a nearby vernal pool complex.

1 to 4 p.m. at the Harris Center. For more information or to register, please contact Brett at (603) 358-2065 or by email.
