Understory patch dynamics and ungulate herbivory in old-growth forests of Olympic National Park, Washington
Schreiner EG, Krueger KA, Happe PJ, Houston DB. 1996. Understory patch dynamics and ungulate herbivory in old-growth forests of Olympic National Park, Washington. Canadian Journal of Forest Research. 26:255-265
From the abstract: "The relationship between native ungulates (mainly Roosevelt elk, Cervus elaphus L.) and the occurrence of three patch types in an old-growth (220- to 260-year-old) Sitka spruce (Picea sitchensis (Bong.) Carriere) - western hemlock (Tsuga heterophylla (Raf.) Sarg.) temperate coniferous rain forest was investigated on the Sourth Fork Hoh River in Olympic National Park. The distribution, frequency, and size of two understory patches (grass, moss) and patches where shrubs had escaped herbivory (refugia) were sampled along transects. Vegetation standing crop, percent cover, species richness and equitability along transects were compared with conditions in two 8-year-old 0.5 ha ungulate exclosures."
