Assessment of Connectivity for Wildlife on Federal Lands in Colorado
Paige Singer and Paul Millhouser (Rocky Mountain Wild), September 2019
As human development expands and habitat fragmentation increases, connectivity’s importance continues to grow; federal lands with a mandate to preserve wildlife have a key role to play in preserving connectivity. This study represents the first statewide connectivity analysis of Colorado using state-of-the-art analysis techniques. By evaluating connectivity based primarily on the influence of human activity on the landscape, this study provides an understanding of connectivity that is both science-based and applicable to multiple species.

Evaluating Landscape Connectivity and Habitat Fragmentation Effects on Elk in the Roaring Fork and Eagle Valleys
Paul Millhouser (Rocky Mountain Wild), August 2019
Recent studies conducted by Colorado Parks and Wildlife have identified an alarming decline in elk populations in the Eagle and Roaring Fork valleys of Colorado. This paper applies measures of human influence on the landscape, including habitat fragmentation and landscape connectivity, to the study area in a time series from 1981 to 2017, to identify possible correlations with elk populations changes during that period.

Preserving Biodiversity in an Changing Climate
Author: Alison Gallensky (Rocky Mountain Wild), June 2019
Wild Connections is a regional conservation organization that protects wildlands, native species, and biological diversity in central Colorado. Wild Connections is partnering with Rocky Mountain Wild to analyze the most important places to preserve in their region to ensure biodiversity will persist as the climate changes. This article, from Wild Connections’ Landscape Magazine, introduces the project and explains the Geospatial Modeling techniques that we are using to identify these places.

Habitat Fragmentation Analysis of Boulder County
Authors: Paul Millhouser and Paige Singer (Rocky Mountain Wild), November 2018
Boulder County Parks and Open Space wanted to understand the degree to which human changes to the landscape, including roads, housing, agriculture and other development, has disconnected the county’s remaining areas of undisturbed habitat. BCPOS will use the results of this analysis to help prioritize areas for conservation and to evaluate the effects of proposed future development on wildlife habitat. BCPOS funded this work through their Small Grants program.

Writing Comments That Stick (PDF) 
Author: Tehri Parker (Rocky Mountain Wild), February 2018
Submitting written comments and protests to governmental agencies can be an effective way to make your voice heard, and to protect our natural resources – be it a National Monument, a rare plant species, a recreation area, or land being leased for fossil fuel development. But, all comments are not created equal. In fact, governmental agencies can throw your comments out if you don’t follow the proper procedures. So, let’s take a few minutes to make sure we get it right, and make sure that your time and effort are well spent.

Leasing of National Forest Lands in BLM Oil and Gas Lease Sales 
Author: Rocky Mountain Wild, November 2016
Rocky Mountain Wild wanted to better understand how the U.S. Forest Service determines which specific parcels to authorize the Bureau of Land management (“BLM”) to include in the quarterly oil and gas lease sale auctions. To carry out this task, our team read relevant parts of all documents pertaining to oil and gas leasing for all seven of Colorado’s national forest/national grassland administrative units. This included land and resource management plans and accompanying final environmental impact statements (FEISs), as well as stand-alone analyses (including FEISs) of oil and gas leasing. The analyses dates from 1992 to December, 2015.
