Where to begin? A flexible framework to prioritize caribou habitat restoration

Restoration Ecology, Journal Year: 2023, Volume and Issue: 31(5)

Habitat loss is a leading threat to many species at risk, and as such, the need for habitat restoration widespread. In boreal forests of Western Canada, key management action needed achieve self‐sustaining populations woodland caribou, federally threatened in decline. Hundreds thousands kilometers linear features were created during exploration or extraction oil gas that are no longer used, yet natural regeneration remains stagnated. Only fraction these restored each year, sparking managers prioritize efforts. We developed an algorithm demonstrate how it can be used predict monitor progress towards goals. Our approach based on idea maximizing gain unaltered caribou per unit cost, while allowing inclusion different goals, costs, weighting criteria. ranked landscape units into five zones priority. The largest occurred following highest priority zones, with diminishing returns proceeded. None ranges reached targets when not considering within energy project boundaries, even after all candidate restored. results highlight ambitious, coordinated restoration, improved land‐use planning minimize alteration range. flexibility our by applying framework case study mountain ecosystem.

Balancing wildlife protection and wildfire threat mitigation using a network optimization approach

In boreal forests of North America, land managers often carry out preventive treatments forest fuel for the protection human infrastructure from wildfires. However, these may negatively affect other ecosystem services, such as capacity to sustain wildlife populations. Here, we examine efficacy a strategy aimed at preserving critical movement corridor woodland caribou ( Rangifer tarandus ) in northern Québec, Canada, by raising high-voltage power line conductors above canopy. To assess interplay between objectives and reduction line's exposure wildfires, developed an optimization model that combines protecting wildfires via maintaining suitable caribou. The node detection (CND) problem with habitat connectivity allocates minimum-resistance fixed-width isolated refuges. Our results identify best locations perform fire lessen threat damage while present future climate scenarios. selected treatment mitigate wildfire line. small-budget solutions, was reduced 36–39% current conditions 20–31% climate, compared no-treatment Despite detrimental effects on both industrial asset habitat, approach provides strategies help achieve compromise two values. Such knowledge is timely negative impacts change livelihoods natural ecosystems.
