rectangular microplots placed along the contour and central axis of the 

 circular macroplot to estimate understory cover. In each macroplot, 

 total overstory canopy coverage was estimated for all trees as well as 

 for each tree species. All trees in the macroplot were counted and 

 recorded by size class. A vigorous, relatively open-growing tree of 

 each species within the macroplot was selected and analyzed for growth 

 information. This involved measuring tree height, diameter at breast 

 height (dbh) and removing a core with an increment borer to determine 

 aqe. Tree height was determined using a tape and a Suunto Clinometer 

 for angle measurement. 



Canopy coverage of ell understory species occurring in each microplot 

 was recorded by coverage class, adapted from the method developed by 

 Daubenmire (1959). 



Data for shrubland and grassland stands were gathered using techniques 

 similar to those employed for the understory component of forest 

 stands. In these types, the 20 microplots were spaced at two-meter 

 intervals along a tape stretched along the contour. 



All stands sampled were placed in homogeneous vegetation to avoid 

 ecotones between community types; heavily disturbed stands vere 

 avoided. A general reconnaissance of the study area was used to add 

 rare or uncommon species to the list. In sampled stands, species 

 occurring in the stand but not in the microplots were recorded for
