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

Table 5

Linear regression models of bird abundance based on local and landscape variables transformed by the logistic equation: Guild abundance = (𝐾⁻¹+𝛽₀𝛽_1𝑥)⁻¹. A single predictor is used in each model.
