Potential Jaguar Habitat and Structural Connectivity in and Surrounding the Northwestern Recovery Unit

The goal of this work was to map habitat and connectivity for jaguars (Panthera onca) in southern Arizona and the Northwestern Recovery Unit (NRU) study area. To do this, we followed the general approach outlined by Sanderson and Fisher (2011; 2013) but updated it using finer-grained spatial data and a gradient-based (rather than binary habitat/non-habitat) model using the same observational data on jaguars.

Wildlands Network Comments on the Jaguar Draft Recovery Plan

These comments were written in response to the U.S. Fish and Wildlife Service’s jaguar draft recovery plan, for which the notice of availability and request for comments was published in the Federal Register on December 20, 2016. As a continental conservation organization, Wildlands Network has an interest in the recovery of jaguars and the protection of jaguar habitat in both the United States and Mexico.

Borderlands Connectivity Report

In recent years, Mexican agencies, non-profit groups, and academia have all made efforts to better address connectivity needs in the borderlands region of Sonora and northeastern Chihuahua. Some actions have focused on identifying impacts of U.S. border infrastructure, others have advanced protected area regulations, while still others seek to reduce habitat fragmentation generated by roads with a focus on Highway 2.

This report is our first effort to put some of the information resulting from regulatory actions, wildlife-friendly infrastructure, and research activities, into a series of maps that allows us to identify areas of the highest immediate concern for connectivity along the U.S. border with Sonora and northwestern Chihuahua. Geographically explicit data are not as readily available as literature, so this effort cannot contain all existing research, nor does it cover all fauna impacted by the border wall. Rather, the report focuses on a few wide-ranging species for which data could be readily collected.

Prioritizing Wildlife Road Crossings in North Carolina, 2017

In this study, we identify priority road segments across North Carolina using a suite of characteristics that predicts where wildlife and transportation conflict is greatest. We did this through the development of large, small, and all species models that integrate numerous road characteristics, such as traffic volume, species-specific connectivity data, and proximity to protected natural areas. The models provide a comprehensive outlook on roadways most deserving of intervention for wildlife, nuanced enough to help identify which mitigation structures or retrofits would be most appropriate for the particular species involved.

Greater Grand Canyon Heritage National Monument Fact Sheet

Made up of public lands surrounding Grand Canyon, the proposed Greater Grand Canyon Heritage National Monument is a magnificent landscape held dear by Native American Tribes, Arizonans, and Americans across the country. The area’s rugged cliffs, pine forests, deep canyons and grasslands protect and provide clean drinking water for this parched region and for millions of people downstream who depend on the Colorado River.

Information Packet about the Wildlife Corridors Conservation Act

This bill would establish the National Wildlife Corridors System to provide for the protection and restoration of native fish, wildlife, and plant species. The conservation of landscape corridors and waterways, where native species and ecological processes can transition from one habitat to another, is critical to conserving biodiversity and ensuring resiliency for wildlife—especially in the face of climate change.

Wildways Fact Sheet

We use highways to go places. Other animals use wildways. If your family wants to travel from Florida to Maine, say, or California to Washington—perhaps to escape summer heat—you can easily drive the distance on I-95 or I-5. A comparable journey would not be so effortless for a cougar or a wolf in search of a new homeland. To travel long distances, wide-ranging species like cougars, wolves, bison, songbirds, and salmon need protected webs of continuous habitats—or wildways.

Proposed Zion Black-Mountain and Bull Valley-Mountain Home Wildlife Corridor ACECs

The Federal Land Policy and Management Act of 1976 (FLPMA) directs BLM to “give priority to the designation and protection of areas of critical environmental concern (ACECs)” that require “special management attention…to protect and prevent irreparable damage to important historic, cultural, or scenic values, fish and wildlife resources or other natural systems or processes,” or to protect people from natural hazards.

Planning for Connectivity

This guide focuses on requirements established under the National Forest System land management planning rule to manage for ecological connectivity on national forest lands and facilitate connectivity planning across land ownerships. The purpose of the guide is to help people inside and outside of the Forest Service who are working on forest plan revisions to navigate these complex connectivity requirements.
