- Title
- Litterfall rates in Reference Stand within the Andrews Experimental Forest, 1977-1985
- Abstract
- Seasonal and annual rates of litterfall have been sampled at 6 permanent plots picked to represent a range of habitats and elevations. To assess variation in litterfall and decomposition and its role in nutrient cycling across an environmental gradient of moisture and temperature. This study is to be incorporated with others in the western and northern US to study the relationship of climate and vegetation on litterfall rates and decomposition.
