Harvesting trees in riparian buffers

November 27, 28, 2007

Cut trees (shrub 25, green ash 18, and silver mapel 21) in Lonnie Strum site.

Randomly selected 5 shrub, 3 green ash and 3 silver maple for biomass measurement.

Weighed the sample trees and shrubs.

Collected wood samples for determining moisture contents, carbon and nitrogen.
