Litter Fall Collection Data

The litterfall study was designed to assess the quantity of biomass (leaves, twigs, reproductive materials) falling from tree species in different ecosystem types. Three study sites selected were:  (1) the pinyon-juniper woodland site near Cerro Montoso on the Sevilleta NWR; (2) the cottonwood forest LTER site along the Rio Grande at Bosque del Apache NWR; and (2) the old-growth spruce-fir-aspen site near South Baldy in the Magdalena Mountains (Cibola National Forest).  The study was conducted over two years (1992-1993) to compare litterfall rates and quantities among sites, seasons and years.
