SSHCZO -- Vegetation -- Leaf Area Index -- Shale Hills -- (2010)

OVERVIEW

Description/Abstract

Leaf Area Index (LAI) and Canopy Closure (CC) were measured from April to October of 2010 at up to 70 points in the watershed about every two weeks (twice a month). At each point, LAI and CC were measured in four directions and averaged. Soil moisture was measured at many of the same points on a regular basis. LAI was measured using a LAI-2200 instrument (LI-COR Biosciences). Canopy closure was measured with a spherical densiometer, Model C Forest Densiometers).
