A distribution-oriented approach to support landscape connectivity for ecologically distinct bird species

Area of Science:

• Ecology
• Conservation Biology
• Landscape Ecology

Background:

• Conserving biodiversity in human-impacted landscapes necessitates managing landscape connectivity.
• Planning connectivity for multiple, ecologically distinct species presents significant challenges.

Purpose of the Study:

• To develop a spatially-explicit framework for identifying and prioritizing conservation and restoration actions for landscape connectivity.
• To assess connectivity needs for distinct bird guilds (forest-specialists, farmland-specialists, generalists) in a heterogeneous agricultural landscape.

Main Methods:

• Analysis of environmental variables to understand guild-specific responses to landscape structure.
• Identification of pivotal sites for maintaining current connectivity for multiple bird guilds.
• Determination of sites for restoration to maximize overall landscape connectivity.

Main Results:

• A small number of sites were identified as crucial for maintaining simultaneous connectivity for all three bird guilds.
• An even smaller subset of sites was identified as critical for maximizing landscape connectivity for the entire regional bird assemblage.
• The study revealed generalities in guild-specific responses to landscape structure.

Conclusions:

• The developed framework provides valuable decision-making support for conservation practitioners.
• Prioritizing key connectivity and restoration sites is essential, especially in rapidly changing agroecosystems.
• Effective landscape connectivity management benefits multiple species with distinct habitat affinities.
