LANDSCAPE-LEVEL THRESHOLDS AND NEWT CONSERVATION

Landscape-level thresholds, and newt conservation.

Ecological thresholds are defined as points or zones at which a rapid change occurs from one ecological condition to another. The existence of thresholds in species-habitat relationships has important implications for management, but the lack of concordance across studies and the wide range of methods used make generalizations difficult. We used two different statistical methods to test for the...

Identifying and prioritizing ungulate migration routes for landscape-level conservation.

As habitat loss and fragmentation increase across ungulate ranges, identifying and prioritizing migration routes for conservation has taken on new urgency. Here we present a general framework using the Brownian bridge movement model (BBMM) that: (1) provides a probabilistic estimate of the migration routes of a sampled population, (2) distinguishes between route segments that function as stopov...

The Future of Landscape Conservation

Biodiversity Conservation through Landscape Ecology

Viet Nam’s landscape is constantly changing as land use changes. Sometimes the resources base benefits where forests are protected and allowed to regenerate naturally, bare land is reforested, or where swidden land is converted to more intensive agriculture. Sometimes resources are lost where forests are exploited for timber, cleared for agricultural or grazing, or burnt by spreading wildfires.

Bigger is better: Improved nature conservation and economic returns from landscape-level mitigation

Impact mitigation is a primary mechanism on which countries rely to reduce environmental externalities and balance development with conservation. Mitigation policies are transitioning from traditional project-by-project planning to landscape-level planning. Although this larger-scale approach is expected to provide greater conservation benefits at the lowest cost, empirical justification is sti...
