often stopping at the foot of slopes, and in timber, 

 or along ridge tops which bear scattering lines of trees. 

 Sometimes they form fongue-like extensions up exposed 

 ridges. Charred stumps, snags, roots and lone trees 

 are to be found in most brush-fields. 



As compared with tree growth, most shrubby species 

 are more fire resistant and prolific. J. V. Hoffman 

 observed the sprouting capacity of manzanita after fire 

 to be as follows: - 



Manzanita - (A. pungens platyphylla) Sprouting after fie. 

 Kinney Creek Fire - 1915.

Sample plots measured by J. V. Hoffman after amother 

 fire showed that common manzanita (A. manzanita) estab- 

 lished 91 seedlings per square yard where there were but 

 3 bushed per square yard. 



Show gives the formation of a typical brush-field 

 as follows :- 



"An area of 15Q200 acres on the Lower McCloud River 

 and adjacent Squaw Creek watersheds supported, 50 years 

 ago, a mixed stand of yellow pine, sugar pine, douglaa 

 fir and incense cedar, averaging 15 M board feet per 

 acre. In 1875 a fire burned over the area from June to 

 October and killed 50-75/^ of the timber. Following this, 

 the brush spread rapidly. In 1898, another fire occurred 

 on the same area, killing most of the remaining timber.
