| 英文摘要 | The abundance of shrubs, salal and salmonberry in particular, is a characteristic feature of the understory in old-growth, west coast forest stands. We analyzed relationships between forest canopy cover and the cover of the shrub layer, salal, salmonberry, herb layer, and moss layer using data from 157 early-seral (35 year-old) stands from west Vancouver Island having variable canopy cover, canopy species, and site quality. The analysis indicated that (i) canopy cover was influenced by canopy species and site quality, (ii) canopy cover had a strong influence on the cover of shrubs but no influence on the cover of herb and moss layers, and (iii) site quality had a moderately strong influence on the cover of salal and salmonberry and a weak influence on the cover of shrub, herb, and moss layers. As the canopy cover decreased from 95 to 5%, the shrub cover consistently increased from about 5 to 95%. The canopy cover alone was a good predictor of the cover of shrubs (R(2) = 0.83), salal (R(2) = 0.72), and salmonberry (R(2) = 0.73), providing the stands were stratified into poor and rich soil nutrient strata. The quantified relationships between canopy cover and the cover of shrubs, salal, and salmonberry provide a simple tool for foresters to manipulate canopy cover of early-seral stands in perhumid cool mesothermal climates for creating suitable wildlife habitats. |
