2 This slideshow is the product of three months of monitoring and data collection and interpretation

4 C-7 Trees The Majority of trees in C-7 consists of Douglas Fir with the exception of one Scouler’s Willow.

5 Snags C-7 consists of 4 snags within 10 m of the plot center. There are 38 snags within 30 m of the plot center. 84.2105% of the snags are Douglas Fir (PSME). The remaining snags are unrecognizable. The average Diameter Breast Height (DBH) is 8.7 in. The average Height is 40.3 ft. The average decay class of these snags is 4.6. The large number of snags may be due to a root fungi migrating through plot C-7

6 Root Fungi The root fungi predominantly affects the Douglas fir population, shrubs and other trees do not seem to be affected by the fungi. If the fungi migrates fairly fast, most of the trees within plot C-7 will soon be affected by the disease.

7 The height of the snags varies from 3 ft to 122 ft

8 Blue = Snags Above 20ft. Height (30 M Plot) Red = Snags Below 20ft. Height (30 M Plot) Yellow = Snags Above 20ft. Height (10 M Plot)

9 We collected rainfall every 2 weeks unless heavy precipitation required more frequent collection
