Noxious Plants are what we refer to as plants which should generally be avoided on hikes, since in many people they result in an uncomfortable allergic reaction.

Following are descriptions of the most common such plants as found along the Hockanum River trails. While a sample Web page is provided, you can find additional information by typing in the name of the plant into a standard Web search engine such as Google.

 Poison Ivy:
Poison ivy is a very common plant found in most parts of the United States. It has 2 forms: One form grows low to the ground. It is usually found in groups of many plants and looks like weeds growing from 6 to 30 inches high. The other form is a hairy vine that grows up a tree. Both have stems with 3 leaves.

 Stinging Nettle:
Stinging Nettles are plants which stand up to 2-4 feet high and which, if brushed by exposed skin, can result in an immediate and painful reaction. This is the caused by needles which are part of the plant and which release acid as a defense mechanism. The reaction can last from a half to several hours, depending on the sensitivity of the person affected.
