It was an open pasture with main grass species of Anaphalis
triplinervis, Artemisia vulgaris, Aconitum heterophyllum, Bergenia stracheyi, Dactylis glomerata, Bistorta affinis, Potentilla eriocarpa and Poa bactriana (Table III).
Subsequent expansion within potholes appears to favor species that produce many poorly dispersed seeds (e.g., Carex spp., Saxifraga and Spraguea), those with strong rhizomatous growth (e.g., Anaphalis and Agrostis) and woody species (e.g., Penstemon and Luetkea).
Del Moral and Clampitt (1985) and Tsuyuzaki and Titus (1996) showed that many of the taxa common in potholes (e.g., Anaphalis and Epilobium) germinated poorly in fine-textured substrates.
A third site, PE, on moist silt/mud deposits from an intermittent wash, supported a dense, varied herbaceous community, with Epilobium spp, Lupinus lepidus, Anaphalis
margaritacea and Salix spp.
Wood and del Moral (1988) documented the pattern of plant establishment over the Pumice Plains 6 yr after the eruption and found that three species - Anaphalis margaritacea (L.) B.
Anaphalis margaritacea and Epilobium angustifolium (hereafter referred to as Anaphalis and Epilobium, respectively) are both perennial, rhizomatous, herbaceous species common as wind-dispersed ruderals on disturbed sites at low- to mid-elevations in the Cascade Mountains of the Pacific Northwest.
Two previous studies have shown that growth and survivorship were generally higher in Anaphalis than in Epilobium on the Pumice Plains, and higher rates in both species were associated with higher soil moisture (Morris and Wood, 1989; Wood and Morris, 1990).
This study compared physiological and morphological characteristics of Anaphalis and Epilobium to determine what differences might explain their relative colonization success.
Both Anaphalis and Epilobium were major components of the vegetation of this clear cut, which appeared typical of such sites in the area surrounding Mount St.
- Diurnal water relations of Epilobium and Anaphalis were compared at the Bean Creek site on 2 dates in August 1986 during a period of dry, warm weather.
