This project would increase diversity of forbs and invertebrates in riparian and transitional riparian/upland areas through mowing and seeding of native forb species. A tractor powered mower with a seeder would be used to create an enhanced vegetative mosaic within riparian or transitional riparian areas lacking in vegetative species and structural diversity. A contractor would provide a tractor or seeder for distribution of native seed. This project would focus on improving habitat for a diversity of species, particularly sage grouse and other BLM sensitive avian species such as the Brewer's sparrow and sage thrasher, which rely on riparian habitats for critical brood rearing requirements in the Sand Hills ACEC...

Project Synopsis: the Ferris Mountain project area consists of mainly timbered slopes, interspersed with upland areas dominated by sagebrush, grass, and mountain shrub communities. Timber stands within the project unit consist of Douglas fir, subalpine fir, spruce, lodgepole pine, limber pine, and aspen, in addition to scattered locations of Rocky Mountain juniper. Long-term suppression of wildfires has promoted the encroachment of conifers into shrublands, aspen stands, and drainages supporting aspen, waterbirch and willows, to the point where many of these communities are non-functional. Decadence and disease is commonly observed in terms of mistletoe, blister rust, and bleeding rust, and pine beetles have...
This project had two primary goals: 1) To develop a process for integrating data from multiple sources to improve predictions of climate impacts for wildlife species; and 2) To provide data on climate and related hydrological change, fire behavior under future climates, and species’ distributions for use by researchers and resource managers. We present within this report the process used to integrate species niche models, fire simulations, and vulnerability assessment methods and provide species’ reports that summarize the results of this work. Species niche model analysis provides information on species’ distributions under three climate scenarios and time periods. Niche model analysis allows us to estimate the...

The National Forest Management Act (NFMA) of 1976 requires every national forest or grassland managed by the U.S. Forest Service to develop and maintain a Land and Resource Management Plan (often referred to as a forest plan). The forest plan is the principle long-range guidance document for each forest or grassland, providing direction for project and activity decision making. Forest plans articulate goals and objectives, the kinds of uses that are suitable for areas of a national forest, management standards and guidelines that apply to different kinds of activities, and the designation of special areas like Research Natural Areas. Forest plans are strategic in nature and do not compel any action or authorize...

Vegetation and land-cover changes are not always directional but follow complex trajectories over space and time, driven by changing anthropogenic and abiotic conditions. We present a multi-observational approach to land-change analysis that addresses the complex geographic and temporal variability of vegetation changes related to climate and land use. Using land-ownership data as a proxy for land-use practices, multitemporal land-cover maps, and repeat photography dating to the late 19th century, we examine changing spatial and temporal distributions of two vegetation types with high conservation value in the southwestern United States: grasslands and riparian vegetation. In contrast to many reported vegetation...

The Pima County Information Technology Department is pleased to introduce PimaMaps, Pima County's next generation web mapping system that will eventually replace the current MapGuide system. The Main MapGuide Map, will remain available for a substantial amount of time while PimaMaps is fully implemented. While MapGuide has been a very reliable web mapping system for many years, it is no longer supported by Autodesk. PimaMaps is based on new technology, provides a more robust and modern interface comparable to Google and Bing, and offers a richer set of functionality beyond what is available with MapGuide. This version of PimaMaps has the following functionality and enhancements that are not available with MapGuide:...
What are current conditions for important park natural resources? What are the critical data and knowledge gaps? What are some of the factors that are influencing park resource conditions? Natural Resource Condition Assessments (NRCAs) evaluate and report on the above for a subset of important natural resources in national park units (hereafter, parks). Focal study resources and indicators are selected on a park-by-park basis, guided by use of structured resource assessment and reporting frameworks. Considerations include park resource setting and enabling legislation (what are this park's most important natural resources?) and presently available data and expertise (what can be evaluated at this time?). In addition...

Natural landscapes in the Southwestern United States are changing. In recent decades, rising temperatures and drought have led to drier conditions, contributed to large-scale ecological impacts, and affected many plant and animal species across the region. The current and future trajectory of climate change underscores the need for managers and conservation professionals to understand the impacts of these patterns on natural resources. In this regional assessment of the Southwest Climate Change Initiative, we evaluate changes in annual average temperatures from 1951–2006 across major habitats and large watersheds and compare these changes to the number of species of conservation concern that are found within these...

For the Green River Basin Landscape Conservation Design (GRB LCD) assessment, we mapped the vulnerability of riparian habitat for terrestrial species and process. Using a vulnerability framework, we defined Sensitivity (S) as the percent riparian vegetation within the valley bottom and Exposure (E) as the amount of human modification within the valley bottom. For each 12-digit hydrologic unit code within the GRB LCD we summarized the riparian sensitivity and exposure to human modification. We also computed Potential Impact (PI), and Adaptive Capacity (AC) metrics at the HUC12 level. PI is the square root transformed product of human modification exposure and riparian sensitivity. AC for riparian exposure to human...
Conclusions:Variability in buffer width across a landscape has important effects on landscape discharge. A variable- width buffer retains less material than a uniform-width buffer of equivalent average width.Thresholds/Learnings:
Groundwater is a key driver of riparian condition on dryland rivers but is in high demand for municipal, industrial, and agricultural uses. Approaches are needed to guide decisions that balance human water needs while conserving riparian ecosystems. We developed a space-for-time substitution model that links groundwater change scenarios implemented within a Decision Support System (DSS) with proportions of floodplain vegetation types and abundances of breeding and migratory birds along the upper San Pedro River, AZ, USA. We investigated nine scenarios ranging from groundwater depletion to recharge. In groundwater decline scenarios, relative proportions of tall-canopied obligate phreatophytes (Populus/Salix, cottonwood/willow)...
We examined patterns of non-native plant diversity in protected and managed ponderosa pine/Douglas-fir forests of the Colorado Front Range. Cheesman Lake, a protected landscape, and Turkey Creek, a managed landscape, appear to have had similar natural disturbance histories prior to European settlement and fire protection during the last century. However, Turkey Creek has experienced logging, grazing, prescribed burning, and recreation since the late 1800s, while Cheesman Lake has not. Using the modified-Whittaker plot design to sample understory species richness and cover, we collected data for 30 0.1 ha plots in each landscape. Topographic position greatly influenced results, while management history did not. At...
Ecological indicators can be used to detect, diagnose, and summarize information about environmental problems. Despite these important values, few indicators have been systematically validated. Broad information on relevance, feasibility, estimates of variance, and interpretation of the ecological indicator is needed for initial validation. Comparisons of ecological indicators can only be accomplished if they are contrasted with standard published criteria. In this paper, information on the potential use of butterflies as indicators of riparian quality is provided within a standard framework. Additionally, data from riparian areas along the Arkansas, Green, Pecos, Rio Grande, and Yampa rivers were collected to validate...
Invasion by Tamarix (L.) can severely alter riparian areas of the western U.S., which are globally rare ecosystems. The upper Verde River, Arizona, is a relatively free-flowing river and has abundant native riparian vegetation. Tamarix is present on the upper Verde but is a minor component of the vegetation (8% of stems). This study sought to determine whether riparian vegetation characteristics differed between sites where Tamarix was present and sites where Tamarix was absent during the invasion of the upper Verde. We hypothesized that herbaceous understory and woody plant communities would differ between Tamarix present and absent sites. Our hypothesis was generally confirmed, the two types of sites were different....
Tamarix spp. removal has been proposed to salvage water and allow native vegetation to recolonize western U.S. riparian corridors. We conducted wide-area studies on the Lower Colorado River to answer some of the scientific questions about Tamarix water use and the consequences of removal, combining ground surveys with remote sensing methods. Tamarix stands had moderate rates of evapotranspiration (ET), based on remote sensing estimates, averaging 1.1 m/yr, similar to rates determined for other locations on the river and other rivers. Leaf area index values were also moderate, and stands were relatively open, with areas of bare soil interspersed within stands. At three Tamarix sites in the Cibola National Wildlife...
The objective of the project is to improve the infrastructure of the Red Rim Wildlife Habitat Management Area (WHMA) as well as conduct habitat improvements. Two windmills will be upgraded to solar pumps and panels. Six and a half miles of fence will be converted from woven wire to wildlife friendly fencing and 8 miles of fence will have single strand conversion to meet BLM and WGFD wildlife standards (i.e. the bottom wire is too low or the top wire is too high). An exclosure will be erected around a riparian area to keep cattle out, sagebrush will be thinned (approx. 140 acres), weeds will be treated (approx. 200 acres) and native grasses and legumes sown (approx. 170 acres). The Red Rim WHMA is located southwest...
