Contains coarse woody debris measurement in a unit of
line intersect sampling.
Description
These are log-level variables measured in the field in a single
line intersect sampling (LIS) unit. The length of the
line or transect is 30 m. Details on this type of
sampling strategy can be reviewed in Gregoire and Valentine (2008).
Usage
cwd
Format
Data contains the following columns:
- element
Element (i.e., log) number with the LIS sample.
- diam
Diameter of the element, in cm.
- len
Length, in m.
- ang
Angle of the element with respect to the line
sampling, in degrees.
Source
Data from Marshall et al 2000.
