Plant Community Response To Fire: A Chronosequence Study, Scott R. Abella, E. Cayenne Engel

Public Policy and Leadership Faculty Research

Fires are becoming more prevalent events across the landscape in the southwestern US. Over the next several decades the already arid southwest is predicted to become warmer and drier, with longer summers, and an increase of “extreme” weather events such as lightening inducing thunderstorms. While the “hotter and drier” forecast may indicate less abundant plant life, and thus less available biomass for fuel, exotic invasive plant species are becoming more dominant across the landscape with increases in human travel and commerce. Exotic species (particularly many of the invasive grasses) are adding fuel for the fires to burn when the annuals …

Finicky Fish Finish... Last! Pre-Visit Lessons (Grade 5), Discover Mojave: Forever Earth

Curriculum materials (FE)

In “Finicky Fish Finish…Last!” students use the Forever Earth vessel to explore what has happened to the Colorado River and the reasons why it is so difficult for the razorback sucker to thrive in a changed environment. Working as ichthyologists (fish biologists) at Lake Mead, students collect water quality data such as temperature, pH, and clarity -- to determine whether current habitat conditions are sufficient for survival of young razorback suckers. Students observe and identify non-native fish in Lake Mead as they learn how the razorback sucker interacts with these neighbors. Students assess whether Lake Mead is still a good …

Management Techniques For The Control Of Sahara Mustard (Brassica Tournefortii) In The Mojave Desert, Dianne N. Bangle, Scott R. Abella, Public Lands Institute,

Vegetation Monitoring Presentations

In the southwestern United States, Brassica tournefortii(Sahara mustard) is a highly invasive plant that colonizes roadsides, beaches, sand dunes, and open desert threatening native annuals. Sahara mustard is believed to contribute to fuel loads in the Mojave Desert in areas where Schismussp. and Bromussp. occur. Sahara mustard may act as ladder fuel, thereby facilitating the spread of fire throughout the landscape. Manpower limitations and insufficient funding limits the abilities of managers to effectively control Sahara mustard. We tested seed germinability in Sahara mustard after fruiting plants were treated with either 2%, 5%, or 12% triclopyr. Sahara mustard seed pods were …

Implications For Management Prioritization Of Exotic Annual Weed Monitoring Near Roadsides In The Eastern Mojave Desert, Usa, Donovan J. Craig, Jill E. Craig, Scott R. Abella, Public Lands Institute,

Vegetation Monitoring Presentations

Invasive exotic plants provide an unnatural conduit for fires in the Mojave Desert. For the last five years, roadside monitoring for exotic invasive species has been a common practice for documenting distributions in Clark County, Nevada (Abella et al., in press). Yet, studies have shown that weed relationships to road corridors differ depending upon the natural system (Hansen and Clevenger, 2005). In the Mojave Desert, it is unknown whether exotic species are limited to or even predominant along roadsides.

Compounding this uncertainty, fertile islands under shrubs are known to enhance conditions for many annuals (Thompson et al., 2005). Thus, a …

Urban Drought Guidebook 2008 Updated Edition, State Of California

Publications (WR)

This guide will help water managers facing water shortages by showing them how to use tried and true methods of the past as well as making use of new tools and methods. Managing water shortages involves using programs to temporarily reduce demand and find alternate water to temporarily increase supply. The guidebook discusses water shortage management programs that belong in water shortage contingency plans. It was first written in 1988, and then updated in 1991 and 2008 to help water suppliers cope with potentially severe drought and other water shortages. The focus of the guide is to provide a step-by-step …

Understanding The Motivations Of Rock Climbers: A Social Worlds Study, Amy Miller Ansari

UNLV Theses, Dissertations, Professional Papers, and Capstones

Rock climbing affects public lands through erosion, destruction of vegetation, and disturbance to historical sites. Minimum impact messages can help reduce impacts but requires understanding characteristics of the message recipient. The purpose of this study was to understand the motivations of rock climbers to help land managers design more effective minimum impact messages. This study assesses the motivations of rock climbers using a social worlds approach, focusing on the sub-worlds of. traditional climbers, sport climbers, and boulderers. I found that traditional climbers are most motivated to pursue a wilderness experience, climb in a natural wilderness setting, and climb in quiet …

Session 7 - Technology And The Creation Of Wilderness: The Making Of Quabbin Reservoir, Timothy J. Farnham

International Symposium on Technology and Society

Large dams in the United States have frequently been the targets of attacks by environmentalists who believe that the dams and the reservoirs they create are violations of wilderness. There are currently numerous proposals to dismantle some dams in order to restore river ecosystems to their pre-dam conditions, including Hetch Hetchy Reservoir’s O’ Shaunnessy Dam. Less attention has been paid to those dams and reservoirs that have arguably created protected areas that otherwise may have been subject to degradation from development. The Quabbin Reservoir, the primary water source for metropolitan Boston, serves as a prime example. Viewed as an engineering …
