摘要

Trees in many forests affect the soils and plants below their canopies. In current high-density southwestern ponderosa pine (Pinus ponderosa) forests, managers have opportunities to enhance multiple ecosystem values by manipulating tree density, distribution, and canopy cover through tree thinning. I performed a study in northern Arizona ponderosa pine-Gambel oak (Quercus gambelii) forests to measure the influences of tree canopy types on understory plant communities and soil properties. On ten 2.5-acre (1-ha) sites, I sampled five 43-feet2 (4-m2) plots below each of the following five canopy types: openings; single ponderosa pine; and Gambel oak single stems, dispersed clumps, and thickets. Soil properties, species richness, plant cover, and the distribution of cool- and warm-season grasses were canopy-type specific. Openings contained the most species/plot, three to eight times greater plant cover than any tree canopy type, and warm-season grasses (for example, purple threeawn (Aristida purpurea)) that were infrequent below trees. In contrast, aspen pea (Lathyrus laetivirens) and Fendlers meadow-rue (Thalictrum fendleri) were most frequent below Gambel oak canopies.
