John Suplee, class of 1969 and member of the Hamilton College Arboretum Advisory Committee, is an established artist who has been painting the College’s trees for almost 50 years. In this visual presentation John will go beyond his paintings to share — for the first time — a generous selection of his documentary photographs and recount his recollections of Hamilton’s arboreal past. Because Suplee’s archive dates from his arrival in 1965, the campus elms and their loss will figure prominently in these images.

Arboretum Director Terry Hawkridge will give a presentation on important sustainable landscape principles and practices: reduced pesticide and fertilizer usage; management of storm water; the usage of alternate products with the least impact on natural resources; landscapes that reduce heating and cooling costs; and ways to reduce the Urban Heat Island Effect.

Ernest H. Williams is a professor of biology at Hamilton and author of The Nature Handbook: A Guide to Observing the Great Outdoors. When we look in the natural world around us, many intriguing patterns can be noted. For this talk Professor Williams will show photos of a number of these observations, mostly from plants and their associated animals, and describe the surprising stories that underlie them. The middle of winter is a good time to focus on the wide array of observations in nature and understand why these patterns exist.
A dormant tree identification clinic will start off in the auditorium to brush up on tree characteristics used to identify winter trees and then migrate outside, with a cup of hot chocolate, for a one-hour tree tour across the College campus with Arboretum Director Terry Hawkridge.
