Factors Influencing Liana Species Richness and Structure following Anthropogenic Disturbance in a Tropical Forest, Ghana

Table 4

Multiple regression (stepwise) analysis of the effects of environmental variables on liana species richness and structure (abundance, dbh, and basal area) in the Southern Scarp Forest Reserve. The final model included only those variables which made significant influence on the dependent variables.

Liana abundance	68.27	Exchangeable calcium	0.000
		Exchangeable magnesium	0.000
		TEB	0.000
		Exchangeable sodium	0.044
Liana DBH	66.67	pH	0.044
		Exchangeable magnesium	0.021
		Exchangeable potassium	0.022
Basal area	76.23	pH	0.011
		Exchangeable magnesium	0.042
		Exchangeable sodium	0.006
