7. Inventory your trees

Do you know how many trees you have in your yard, exactly? Does your local park know the specific number of trees under their care? By simply taking an inventory of the number, species and condition of the trees around us, we become better equipped to appreciate and maintain our local canopy.

Areas of Interest: Looking Around, Thinking, Investigating, Walking, Writing
Ingredients: Pen and paper, map, tree identification guide
Directions: Draw a map of your property with a box representing your house. Number and identify each tree in its approximate place surrounding your house. For a school, park, or street this can be done on a larger scale or with multiple pieces of paper. You also can request a campus, park or parcel map.
Choose useful data. Some suggestions are:
* Number of trees in a designated area
Count the number of trees in your designated area.
* Location of each tree, defined by
1) street address
2) location relative to property lines, buildings, streets, and other trees
* Species of each tree
Using a tree identification guide, identify the species being inventoried.
* Condition or health of each tree
Look for signs of disease or of hazardous conditions, such as pests, mistletoe, rot, missing bark, damaged limbs, or dead/missing leaves during non-dormant seasons. Note if the tree is young, mature or in decline.
* Special needs of certain trees
Identify tree needs such as watering, pruning, mulching, fertilization, staking or stake removal.
