Analyzing land-use change scenarios for trade-offs among cultural ecosystem services in the Southern Rocky Mountains
By Ben Sherrouse, Darius Semmens, Zach Ancona, and Nicole Brunner. Published by Ecosystem Services.
U.S. forests, including those of the Southern Rocky Mountains, are projected to see significant increases in outdoor recreation participants by 2060. This will challenge forest managers to balance increasing demand for outdoor recreation with other ecosystem services. Using the GIS tool, Social Values for Ecosystem Services (SolVES), this study analyzed land-use change scenarios based on road-network expansion to quantify changes in aesthetic and recreational ecosystem service values. Trade-offs between these values relative to forest stakeholder groups defined by their attitudes regarding motorized recreation were also assessed. Though trade-off assessments between aesthetic and recreational ecosystem service values indicated that areas of conflicting value changes were limited, the approach this study outlines could be an important means of conflict resolution for multi-use management.

Research Ecologists Jenny Briggs and Erin Berryman, Research Geologist Natalie Kehrwald, and Student Volunteer Marianne Blackburn represented the GECSC at a major science education and outreach event titled "Girls & Science" at the Denver Museum of Nature and Science. The event introduced children and families to the work and career paths of female scientists in more than 25 organizations at Federal, State, and local levels. Over 12,000 visitors of all ages and backgrounds attended.

Vertebrate paleontology, stratigraphy, and paleohydrology of Tule Springs Fossil Beds National Monument, Nevada (USA)
By Kathleen Springer (GECSC), Jeff Pigati (GECSC), and Eric Scott. Published by Geology of the Intermountain West.
Tule Springs Fossil Beds National Monument preserves 22,650 acres of the upper Las Vegas Wash, and is home to extensive and stratigraphically complex groundwater discharge deposits which represent springs and desert wetlands that covered much of the valley during the late Quaternary. The deposits record hydrologic responses to abrupt climatic oscillations over the last ~300,000 years as well as entomb the Tule Springs Local Fauna, one of the most significant late Pleistocene (Rancholabrean) vertebrate assemblages in the American Southwest. This field compendium highlights the faunal assemblage in the classic stratigraphic sequences of the Las Vegas Formation within the National Monument, emphasizes the significant hydrologic changes that occurred in the area during the recent geologic past, and examines the subsequent and repeated effect of rapid climate change on the local desert wetland ecosystem.
