Understanding the abiotic drivers of high-elevation forest physiognomy is essential for forecasting how mountain ecosystems will respond to emerging environmental pressures. Most prior studies of these relationships have relied on small samples of the full landscape, resulting in limited power to de

The Uncompahgre Uplift within the Colorado Plateau contains several salt anticline valleys. The Moab Valley is situated within one of these valleys which formed as the underlying salt member of the Paradox Formation migrated. As the unit migrated, the resulting collapse of the valley left behind sur

Clifford Duncan, a Northern Ute elder, believed in educating the public to know and understand the meaning of Ute petroglyphs. By doing this, he believed it would help to preserve and protect them. Over the course of eight years, Clifford and the author visited and revisited all of these sites, disc

A comparatively new kind of plant materials challenge has entered the picture in Colorado in recent years. This is revegetation at high elevations.

In the American Southwest, a growing population combined with climate change induced weather pattern changes are creating growing conflict for uses of the over appropriated Colorado River System. Water managers use a variety of tools and data to make decisions at the local and regional level which w

After the Second World War, America saw a decline in ridership on transit systems which eventually resulted in the dismantling and abandonment of many rail systems. The primary mode of public transportation shifted from transit to buses, which used the same streets and competed with the same infrast

Three species of Diuraphis in addition to the Russian wheat aphid , Diuraphis noxia (Mordvilko), occur in western Colorado . Diuraphis (Holcaphis) tritici (Gillette), the western wheat aphid, and Diuraphis nodulus (Richards) were collected near Meeker (Rio Blanco County) in 1990. Both species were f

Fens are a widely distributed type of wetland worldwide and offer vital habitat for plant and animal species in the Rocky Mountains. Fens support a high biodiversity of flora and fauna given the proportionally small space they occupy on the landscape, often serving as refugia for disjunct plant spec

This chapter discusses the arc of Carolyn Merchant’s direct and indirect influences on work, particularly now forming a bridge between completed landscape history of Point Reyes National Seashore here in northern California, and developing a new focus on the history of the Rocky Mountain Biological

What is coal?" is a question that doubtless has often occurred to the thoughtful miner, who has worked perhaps all his life in coal mines, in England, Pennsylvania or Colorado, and is practically familiar with the substance in nearly all its known forms and with nearly every condition under which it

by working out and applying advanced methods of forestry.Thus the forester's first job 1s to keep the woods from burning.Time is a factor of the highest importance in getting to forest fires and there must be ample provision

Abstract We propose that many Tertiary man to orebodies typical of Leadville and adjacent districts of Central Colorado (northern Sawatch range and Mosquito range) are modifications to pre-existing mineralized paleokarst cave systems (Tschauder and Landis, 1985; Landis and Tschauder, 1985). Major ka

The aim of this work was to assess the performance of the Kipp and Zonen Large Aperture Scintillometer (LAS; Delft, Netherlands) to predict surface sensible heat flux (H). The LAS was introduced approximately 30 years ago and has been marketed as an indirect tool for the estimation of vegetation eva

which, following Aldenderfer (2006), we define as locations at elevations greater than 2,500 meters above sea level (e.g.,

Fifty years ago, riparian habitats were not recognized for their extensive and critical contributions to wildlife and the ecosystem function of watersheds. This changed as riparian values were identified and documented, and the science of riparian ecology developed steadily. Papers in this volume ra

The ecological impacts of selenium have been studied for decades and regulatory standards established in an effort to mitigate them. Agricultural activities in regions with high levels of alluvial selenium can lead to in-stream levels that far exceed regulatory limits. Agricultural best management p
