Scientific Papers

Canyonlands Natural History Association is a non-profit organization devoted to supporting the educational and interpretive programs and scientific research efforts of the National Park Service, the Bureau of Land Management, and the USDA Forest Service in southeast Utah. These efforts are funded in part by CNHA memberships. Additionally, twenty percent of each sale from our retail outlets and online store supports efforts of the parks and recreation areas in this region.

Many of the scientific research projects we fund result in papers that are published by the sponsoring agency or by peer-reviewed academic journals. We are starting to obtain permission to make these papers available for free download from our website for personal and educational use.

The papers available here require Adobe Acrobat Reader for viewing. For best results, save the file to your computer and open it from there.

The following files are available:

The Archeology of Horseshoe Canyon The Archeology of Horseshoe Canyon
Horseshoe Canyon in Canyonlands National Park contains some of the most evocative rock art in the world. This 74-page book is a collection of articles devoted to the archeology of this remote canyon by some of the most renowned archeologists in the field.
Assessment of Riparian Vegetation Monitoring Approaches Assessment of Riparian Vegetation Monitoring Approaches
The riparian monitoring was done in Arches NP and Natural Bridges NM during the summer of 2006. The monitoring of these approaches helped to ensure proper reporting of the ecosystems health and provide early warning of system degradation.
Assessment of Biological and Physical Relationships of Spring and Seep Ecosystems Across a Gradient of Human Impacts Assessment of Biological and Physical Relationships of Spring and Seep Ecosystems Across a Gradient of Human Impacts
This study investigated the relationship between anthropogenic disturbance and aquatic macroinvertebrate community species composition at springs on the Colorado Plateau.
Erigeron mancus Elevational Density Gradient as a Baseline to Detect Future Climate Change in LaSal Mountain Habitats Erigeron mancus Elevational Density Gradient as a Baseline to Detect Future Climate Change in LaSal Mountain Habitats
This study provides baseline data on the population biology of E. mancus which will then allow future re-measurements to indicate population trends in response to climate change & anthropogenic stressors.
Distance and Temperature Effects on Pika Forage Distance and Temperature Effects on Pika Forage
This research measured both soil surface temperature and plant species composition within and outside of the normal pika foraging zone in order to establish a baseline for future species comparison and temperature change comparisons.
