Trading Cards



Tree

Trading
Cards
As a learning tool to help Envirothon teams, a series of "trading card" sets have been or are being produced for use by teams and for other educators. A suggested donation of $3 per set of 25 cards, plus the cost of S&H, is recommended. The first set of trading cards created by C2E2 were the tree trading cards, representing the 25 native and most common found species of trees in North Dakota. The cards provide a picture of the tree and a leaf, as well as other useful information.


Macro

Trading
Cards
Macroinvertebrates are bottom-dwelling, aquatic organisms large enough to see with the naked eye. Different species of macroinvertebrates have different levels of tolerance to water pollution. By identifying the species of macroinvertebrates in a body of water, you can estimate the quality of water that is present. Macroinvertebrates are directly affected by what happens in a stream. If someone would like additional information about macroinvertebrates they can visit the on-line key at the Digital Key to Aquatic Insects of ND website.


Soil

Cards
The Soil Trading Cards are available for $3 for a set of 26 cards while supplies last. Soil cards go on a first come, first served basis.
