Modeling Aquatic Macroinvertebrate Richness Using Landscape Attributes

Table 2

Eight habitat classifications and the number of sites sampled in each.

Habitat type	Stream gradient	Riparian forest cover	Water quality	Number of sampled sites
HCB	High	Closed	Stressed	10
HCG	High	Closed	Suitable	3
HOB	High	Open	Stressed	5
HOG	High	Open	Suitable	0
LCB	Low	Closed	Stressed	6
LCG	Low	Closed	Suitable	1
LOB	Low	Open	Stressed	13
LOG	Low	Open	Suitable	1

H = high gradient, L = low gradient, C = closed canopy, O = open canopy, G = water quality suitable for life support, and B = water quality biologically stressed.
