Abstract
Red heather (Phyllodoce empetriformis (Sw.) D. Don) recovery after experimental fires and wildfires was studied at five subalpine sites in Washington State, U.S.A. Experimental burn treatments showed that fire had a neutral to positive effect on stem numbers but generally a short-term negative effect on aboveground biomass production. Although there were no differences in effects between experimental burn and clip treatments, long-duration smoldering beyond that documented in our experiments may have more damaging effects. On three wildfire sites, sprouting was vigorous after fire except at one site adjacent to forest cover where significant litter consumption occurred. The duration of fire, rather than its presence or absence, may be an important character of the fire regime in predicting post-fire response of red heather.Key words: red heather, Phyllodoce empetriformis, fire, subalpine meadows, Pacific Northwest.
