Abstract or Summary
  • Models that assess the risk to biodiversity from landscape change can help communities prioritize planning decisions. Accurate representation of the ecology and life history traits of species is necessary. This study introduces the use of habitat quality in a biodiversity risk model to determine the significance of habitat quality when predicting risks to biodiversity due to landscape change. The difference between residential and forest habitats in terms of habitat quality for breeding birds was used to test the significance of habitat quality to the risk model. Relative habitat quality was estimated from population densities for 62 bird species associated with both forest and residential habitats. The effect of habitat quality was tested using two possible future landscapes: Buildout and Spine. Predicted risk for the 62 bird species due to landscape change increased by 74% in the Buildout Landscape and 31% in the Spine Landscape when habitat quality was considered. The life history traits of species most at risk were compared to the traits of species that benefited from the landscape change. Life history traits considered included foraging strategy, nest type and placement, migratory status, and area sensitivity. Species at high risk included ground nesters, foliage and tree trunk gleaners, neotropical migrants, and area sensitive species.
