3. Display pressed leaves on identification sheets
given to you by the instructor.
(The leaves are not brown or have holes in them)
4. Identify the trees by their leaves:
a. Common name

(Remember that scientific names must be
underlined)Find These LeavesThis is your “treasure hunt” list of trees to find in the Parkston area. Remember you need 20 different species of trees in your portfolio. 26 are listed below.

Did You Know:
· Trees help clean the air. They trap dust and filter pollutants, including particulate matter, out of the air. · Forests collect and filter rainwater, and from it generate and store groundwater. · The byproducts of trees, decomposed leaves, branches, and tree trunks, become soil. They also provide a motherlode of nutrients that enrich our soil. · Through growth, transpiration, and death, trees tie up minerals and nutrients from air, water, and soil. · Trees reduce erosion by cutting the speed with which wind and water rush across the landscape. · In very localized ecosystems, strategically placed deciduous trees help cool buildings in summer by providing shade. · Trees generate vast amounts of the oxygen we breathe. · An average tree absorbs and ties up to 26 pounds of carbon dioxide a year, the amount emitted by a car traveling 11,300 miles. · Trees help drive the hydrological cycle, which carries water from sea to air to land and back to the sea again. · We consume vast quantities of fruit, nuts and other foods from trees. · Wood remains a fuel source for heat and cooking in much of the world. Because of availability and low cost, we make heavy use of wood and wood products ranging from lumber, paper, and chemicals to pencils and garden mulch. · Trees are a direct source of cures for a range of ailments. · Studies show that people in hospital rooms affording a view of trees recover more quickly than those in rooms without a tree view.· Close-by trees have been shown to reduce employee stress.
Tutorial for the Identification of Deciduous
Area Trees by their Leaves
The following websites will help you become familiar with area deciduous trees.
Evaluation of Tree Leaf Portfolio
Each tree identification sheet is worth 5 points.
You must collect 20 different leaves and identify the trees by their leaves.
The rubric for the identification sheet is as follows:
· 2 point for display, leaves are not brown or have holes in them, pressed flat and not moldy. Portfolios are nicely done with these pages in it: about the project, find these trees, evaluation and with a table of contents of your leaves. These pages must be in this order in the portfolio.
· 1 point for correct common name on a tag.
· 1 point for scientific name on a name tag.
· 1 point for working in class and meeting deadlines.
Before handing in your portfolio you must let another student edit your project. They might have some great suggestions for you.
Where did you find that tree?
You can create your own map by drawing it free hand or you can use the link below to assist you. Also, the computers in the library are downloaded with Streets and Trips.
- Remember that the Parkston High School is your starting point.
- Your maps have to be very specific with addresses.
- I must know how to get to this address and then an inset map must be included to help locate the tree on the property. ( Don't forget your directional indicator on ALL maps.)
- Organize your leaves behind each map.
