Climatic, topographic, and anthropogenic factors determine connectivity between current and future climate analogs in North America

Publications Posted on: July 27, 2020
As climatic conditions shift in coming decades, persistence of many populations will depend on their ability to colonize habitat newly suitable for their climatic requirements. Opportunities for such range shifts may be limited unless areas that facilitate dispersal under climate change are identified and protected from land uses that impede movement.

Human land uses reduce climate connectivity

Science Spotlights Posted on: July 24, 2020
Climate change will cause many species to shift their ranges.  To do so successfully, individual organisms will need hospitable travel pathways. These climate corridors –the best movement routes between current climate types and where those climates will occur in the future– will be critical for species persistence.

Protected area stewardship in the Anthropocene: Integrating science, law, and ethics to evaluate proposals for ecological restoration in wilderness

Publications Posted on: May 10, 2020
Every year, the four federal agencies that manage designated wilderness in the United States receive proposals to implement small- and large-scale ecological restorations within the National Wilderness Preservation System. The combination of climate change with other landscape stressors is driving ecological restoration to be one of the single most important, challenging, and potentially litigious wilderness stewardship issues.

Human land uses reduce climate connectivity across North America

Publications Posted on: April 16, 2020
Climate connectivity, the ability of a landscape to promote or hinder the movement of organisms in response to a changing climate, is contingent on multiple factors including the distance organisms need to move to track suitable climate over time (i.e. climate velocity) and the resistance they experience along such routes.

Effects of drought on wildfires in forest landscapes of the Western Ghats, India

Publications Posted on: August 06, 2019
Wildland fire is an understudied yet highly important disturbance agent on the Indian subcontinent. In particular, there is uncertainty regarding the degree to which annual climate variation influences inter-annual variability in fire activity. In this study, we evaluate wildland fire at two complementary spatial scales in the southern portion of the Western Ghats mountain range (hereafter ‘Western Ghats’) in India.

Climate change likely to reshape vegetation in North America's largest protected areas

Publications Posted on: May 22, 2019
Climate change poses a serious threat to biodiversity and unprecedented challenges to the preservation and protection of natural landscapes. We evaluated how climate change might affect vegetation in 22 of the largest and most iconic protected area (PA) complexes across North America.

Science and stewardship to protect and sustain wilderness values: Seventh World Wilderness Congress symposium; 2001 November 2-8; Port Elizabeth, South Africa

Publications Posted on: August 01, 2018
The Seventh World Wilderness Congress met in Port Elizabeth, South Africa, in 2001. The symposium on science and stewardship to protect and sustain wilderness values was one of several symposia held in conjunction with the Congress.

Sprawling and diverse: The changing U.S. population and implications for public lands in the 21st Century

Publications Posted on: June 29, 2018
Public lands are typically established in recognition of their unique ecological value, yet both ecological and social values of public lands change over time, along with human distribution and land use. These transformations are evident even in developed countries with long histories of public land management, such as the United States.

Predicting landscape connectivity for the Asian elephant in its largest remaining subpopulation

Publications Posted on: February 17, 2017
Landscape connectivity between protected areas is crucial for the conservation of megafauna. But often, corridor identification relies on expert knowledge that is subjective and not spatially synoptic. Landscape analysis allows generalization of expert knowledge when satellite tracking or genetic data are not available.

Trade-offs and efficiencies in optimal budget-constrained multispecies corridor networks

Publications Posted on: September 29, 2016
Conservation biologists recognize that a system of isolated protected areas will be necessary but insufficient to meet biodiversity objectives. Current approaches to connecting core conservation areas through corridors consider optimal corridor placement based on a single optimization goal: commonly, maximizing the movement for a target species across a network of protected areas.
