HERBACEOUS SPECIES RESPONSE The most abundant native species on the burn is pinegrass. Pinegrass maintains itself in dense forest shade but only produces seed in forest openings.

Cover increases in 1982 may reflect this new growth. Postfire behavior of pinegrass and some other herbs is foimd in table 15. Common fireweed (Epilobium angustifolium) is widely distributed on the burn with low mean cover values of less than one percent. It resprouted from roots (sometimes considered as rhizomes) during spring of 1978 in many ravines and possibly on upland sites. Blooming the first season was profuse on the scattered surviving plants, producing light, wind-blown seeds. Both heartleaf arnica and broadleaf arnica [A. latifolia) are present on the bum. Heartleaf arnica is more generally distributed, while broadleaf arnica is restricted to ravine side slopes. Conspicuous aster is also rhizomatous, with wind-blown seeds. The arnicas form clumps similar to those produced by rhizomatous shrubs and have dispersed Uttle otherwise; the aster is more generally distributed and forms only small clumps. Two other widely distributed ground layer species eire creeping Oregon-grape (Berberis repens), a low subshrub considered in this study with the herbaceous layer, and western meadowrue. They are stoloniferous or. Figure 15.—Pinegrass in bloom during sum- mer 1978. 20.
