Long-term permanent plot studies are used to examine population dynamics of several species. Field and laboratory experiments are used to study seed germination, seedling ecology, and interactions between orchids and mycorrhizal fungi.
Current projects focus on the genetic variability of clonal species in forest and wetland habitats.
Other studies focus on the ecological consequences of interactions between clone members growing in different habitats. Comparative studies in several countries are used to address human effects on nutrient cycling and effects of nutrient limitation on wetland ecology. Wetland assessment techniques, GIS methodologies, and comparative studies of nitrogen cycling are used to evaluate the ecological conditions of wetlands at the scale of an entire watershed. Progress in development of the hydrogeomorphic approach for assessing the functioning of wetlands. Wetlands for the Future.
