FIRE EFFECTS
SPECIES: Arctostaphylos columbiana | Hairy Manzanita 



IMMEDIATE FIRE EFFECT ON PLANT : 
Fire kills hairy manzanita [1,10,18,37].


DISCUSSION AND QUALIFICATION OF FIRE EFFECT : 
NO-ENTRY


PLANT RESPONSE TO FIRE : 
Current information concerning hairy manzanita's response to fire is
limited to studies of its regeneration following clearcutting and slash
burning in Douglas-fir (Pseudotsuga menziesii) forest types.  It was
reported as establishing from seed after such forest management near
Blue River, Oregon [37].  Further details were not available.
Schoonmaker and McKee [29] reported postfire hairy manzanita seedling
recruitment on the H. J. Andrews Experimental Forest, Oregon.  Sites
were broadcast burned and planted with Douglas-fir seedlings.  No hairy
manzanita seedlings were found on transects at postfire year 2, but mean
transect cover value of hairy manzanita seedlings was 0.04 percent at
postfire year 5.  Mean transect cover value was greatest (0.15%) at
postfire year 15.

A comparison of hairy manzanita cover on burned versus adjacent unburned
plots was made near Oakridge, Oregon.  Fire treatment was broadcast
burning of slash.  At postfire year 9, hairy manzanita cover was 3.2
percent on burned plots and 0.3 percent on unburned plots [30].
