Exhibit 02 Dwarf Mistletoe Rating

Dwarf mistletoe occurs on Western Larch, Pines, and Douglas-fir (rarely true fir or spruce). Signs and symptoms include witches brooms (a massed dense clump of tree branches, typically with live foliage), the visual presence of the mistletoe plant (simple or branched shoots, approximately 1 to 4 inches in length), and swellings on the tree stem or branches.

Use the following six-class mistletoe rating procedures:

1. Divide live crown into thirds;

1. Rate each third separately for the amount of infection;

Rating Amount of Infection (within the third) 0 No visible infection 1 Light infection -- one-half or fewer of the total branches infected 3 Heavy infection -- one-half or more of the total branches infected

Add the three individual ratings of the thirds to obtain a total mistletoe rating for the tree; enter the total rating as the Mistletoe Class code.
