Habitat and Landscape Suitability as Indicators of Bird Abundance in Created and Restored Wetlands

Table 4

Pearson’s correlation (r) of diving, dabbling, wading, and emergent-dependent bird abundance with habitat and landscape variables of seven Ohio mitigation bank wetlands. Habitat and landscape variables include a composite Habitat Suitability Index (HSI) value for each guild, wetland area, mean width of upland buffer surrounding each wetland (buffer), connectedness of natural habitat within 2.5 km of each wetland (connect), road density within 1 km of each wetland (Road), Landscape Development Index (LDI), and wetland age. Significance indicated at ^∗𝛼=0.10 and ^∗∗𝛼=0.05.

	HSI	Area	Buffer	Connect	Road	LDI	Age
