Example of a litterfall collector at Harvard Forest LTER, located near the base of an eddy covariance tower. Ecologists measure litterfall mass by placing containers of a known size, typically lined with screen mesh, in the forest, and then collecting whatever falls into the basket at routine intervals. Back in the lab, they then sort this material into various components, which they then oven-dry and weigh. Mesh lining helps drain litter faster, reducing mass loss that can occur in the field.
Example of a litterfall collector at Harvard Forest LTER. Plastic buckets and laundry baskets are commonly used to collect litterfall in forest ecosystems.

A soil core from the Kellogg Biological Station LTER. Biogeochemical data from cores across the LTER network allowed researchers to study the link between the carbon and nitrogen cycles in this synthesis project.
