To investigate “squirrel habitat” (tree canopy) and other features
of your urban forest.
How much squirrel habitat is on your block?How many
trees there are on your block?Why trees are important to us and squirrels?
Street trees are trees alongside the curb in the public
right-of-way. Count the number of street trees on your block.
Measure the circumference (girth) of the biggest and smallest
trees. At around 1.3 meters (or 4.5 ft) up from the ground, measure around the tree’s
Check out your block’s street tree
canopy by using the distance a squirrel leaps. Squirrels live up in the trees and are safer
there than on the ground. Assume squirrels can leap about 2 metres (6 ft or a person’s
height) between branches:Can a squirrel make it from one end of the block to the
other and cross the street at least twice, without coming down to the ground?
If “No”, how many gaps (greater than 2 meters) between
canopies did you see?
