Cris Criscitiello begins the tree walk in the Newton Cemetery at the "Newton Sentry", a very unusual upright form of sugar maple (Acer saccharum, #1 on tree map).

Cris explains the origins of the "Camperdown Elm", a mutant of the English Wych Elm, so named because it was detected in 1840 on the estate of the Earl of Camperdown in Dundee, Scotland. A cutting from this mutant, grafted to the root system of a Wych elm, can be reproduced as the Camperdown Elm (#7 on tree map).

The tour learns about a Japanese Maple.

Mayor Cohen talks with Katherine Howard, President of the Newton Tree Conservancy.

Mayor Cohen plants a new tulip tree, assisted by Marc Welch, Newton's Director of Urban Forestry, local Girl Scouts, and other children including Marc's son.
