TOTAL POINTS: 247
This Bur Oak is the:
MEASURING ITS BENEFIT:

3:30 pm on May 27, 2011, we measured the air temperature:
This tree is a GIANT!
It has the third biggest crown (canopy) of any Bur Oak in Virginia!
Under this broad canopy students, teachers and parents explored the habitat to see what lives with it. The students recorded a blue jay, ground bees, poison ivy, English ivy, a variety of ants, flies, several types of grasses, mushrooms, moths, violets, wild strawberries, buttercup, sorrel, some exposed roots and the sticks, leaves, and acorn parts from last year's growth. In the tree we found eggs and small insects on nearly every leaf. It is clear that this amazing tree supports a great deal of wildlife in this schoolyard!
Bur Oak leaves seen here in "rubbings' by the students, have rounded lobes (it's in the white oak family) with a cross shape and look similiar to a post oak.
Drawings by Johnson students illustrate the Bur Oak shape, bark and parts they found on the tree.
