How is the lot shaped?
On the back of recycled paper, draw a scale map of the lot.
Use a compass to help orient the map properly.
Measure the perimeter of the vacant lot in meters.
Calculate the area in hectares.
If it is partially sloped, calculate the percentage of slope by using a measuring stick, another stick, and a baby food jar half filled with water. See diagram.
How many trees are in the vacant lot?
If you know their names list them below.
If you don't, describe them.
Name or Description
Number
Divide into groups of four. After each group selects a section of the vacant lot to study, do a 100 step Toe Transect (see below) to determine what percentage of the surface is covered by litter, annual grass, perennial grass, forb, shrub, rock and bare soil.
Definitions
Working in groups of four, stretch a 100 foot tape along the ground where you want to inventory the types of plants in your area. This is called a 100 foot transect. Record what you find at every foot along the tape or transect on the table below. Record presence of the item below by putting a check ( ) if present. Leave blank if not present.

What other signs of animals did you see which did not appear in the hoop sample? ______________________________________________________________________________________
Which animals were most prevalent? ___________________ Least? ___________________________
