Table 14.3. Herbaceous community composition in 80 study plots located in young forests. The
presence (1) or absence (0) of Galium aparine, Arisaema triphyllum, Viola canadensis, and
Disporum lanuginosum are indicated for each study plot. Forest patch size (ha) and percent of
old forest in landscape were measured from a land-cover map. Percent of old forest was
measured in a 81-ha window. These data are also contained in an Excel file called “context.xls”
on the CD.
