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.
