Meta-replication reveals nonstationarity in multi-scale habitat selection of Mexican Spotted Owl

Publications Posted on: August 29, 2017
Anthropogenic environmental changes are leading to habitat loss and degradation, driving many species to extinction. In this context, habitat models become increasingly important for effective species management and conservation.

A comparative framework to infer landscape effects on population genetic structure: Are habitat suitability models effective in explaining gene flow?

Publications Posted on: September 16, 2016
Most current methods to assess connectivity begin with landscape resistance maps. The prevailing resistance models are commonly based on expert opinion and, more recently, on a direct transformation of habitat suitability. However, habitat associations are not necessarily accurate indicators of dispersal, and thus may fail as a surrogate of resistance to movement. Genetic data can provide valuable insights in this respect.

Estimating effective landscape distances and movement corridors: Comparison of habitat and genetic data

Publications Posted on: September 16, 2016
Resistance models provide a key foundation for landscape connectivity analyses and are widely used to delineate wildlife corridors. Currently, there is no general consensus regarding the most effective empirical methods to parameterize resistance models, but habitat data (species’ presence data and related habitat suitability models) and genetic data are the most widely used and advocated approaches.

Ecology of Mexican spotted owls

Media Gallery Posted on: October 05, 2015
RMRS scientists have been involved in Mexican Spotted Owl recovery efforts since before the species was listed as Threatened in 1993. Today, our scientists are developing new knowledge of this owl, synthesizing existing information, and working with land managers to integrate habitat requirements for the owl and its important prey species into management plans.

Ecology of the Mexican Spotted Owl

Projects Posted on: August 14, 2015
Rocky Mountain Research Station (RMRS) scientists have been at the forefront of efforts to understand the ecology of the threatened Mexican spotted owls (Strix occidentalis lucida) for more than 25 years. These scientists and their cooperators have produced most of the existing scientific information on this species. Today, RMRS scientists continue to be actively involved in developing new knowledge on this owl, synthesizing existing information, and working with managers to integrate habitat requirements for the owl and its important prey species into land management plans.

ArcHSI (Arc Habitat Suitability Index)

Tools Posted on: August 05, 2014
The Arc Habitat Suitability Index is a geographical information system (GIS) model that estimates the ability of an area to meet the food and cover requirements of an animal species. ArcHSI is a tool intended to inform planners of the probable impacts on wildlife for the alternatives they develop. It is a tool that should augment, not supplant, the expertise of resource specialists with site-specific knowledge.

Habitat suitability models for cavity-nesting birds in a postfire landscape

Publications Posted on: January 03, 2008
Models of habitat suitability in postfire landscapes are needed by land managers to make timely decisions regarding postfire timber harvest and other management activities. Many species of cavity-nesting birds are dependent on postfire landscapes for breeding and other aspects of their life history and are responsive to postfire management activities (e.g., timber harvest).

A test of the habitat suitability model for Merriam's wild turkeys

Publications Posted on: March 22, 2006
An important research area regarding the wild turkey (Meleagris gallopavo) is development of sound habitat models. Habitat models provide standardized methods to quantify wild turkey habitat and stimulate new research hypotheses. Habitat suitability index (HSI) models show species-habitat relationships on a scale of O-l, with 1 being optimum. A proposed HSI model for Merriam’s turkeys (M. g.
