Topock Marsh is a large wetland adjacent to the Colorado River and main feature of Havasu National Wildlife Refuge (Havasu NWR) in southern Arizona. In 2010, U.S. Fish and Wildlife Service (FWS) and Bureau of Reclamation began a project to improve water management capabilities at Topock Marsh and protect habitats and species. Initial construction required a drawdown, which caused below-average inflows and water depths in 2010-2011. Co-applicants Daniels and Haegele of FORT monitored Topock Marsh during the drawdown and immediately after, thus obtained information on immediate effects. However, stress from the drawdown may have a delayed effect on aquatic resources; additionally, significant changes to the infrastructure...

California’s State Wildlife Action Plan (SWAP) is a comprehensive, statewide plan for conserving the state’s fish and wildlife and their vital natural habitats for future generations. It is part of a nationwide effort by all 50 states and five U.S. territories to develop conservation action plans and participate in the federally authorized State and Tribal Wildlife Grants (SWG) Program. The purpose of the SWG Program is to support state actions that broadly benefit wildlife and habitats, but particularly the “Species of Greatest Conservation Need” (SGCN) identified by the individual states. Each state has prepared a SWAP that assesses the health of the state’s wildlife and habitats, identifies the problems they...

NatureServe worked with several federal, state, and NGO partners in the United States and Mexico to conduct a climate change vulnerability assessment of major natural community types found within the Mojave and Sonoran Deserts. The project focused on ten major upland, riparian, and aquatic community types, including pinyon-juniper woodlands, Joshua tree-blackbrush scrub, creosote-bursage scrub, salt desert scrub, Paloverde-mixed cacti scrub, semi-desert grassland, desert riparian and stream, riparian mesquite bosque, and desert springs. This effort piloted a new Habitat Climate Change Vulnerability Index (HCCVI) approach being developed by NatureServe, as a companion to an existing index for species. The project...

Funded by Arizona Game & Fish Department, our team of conservation biologists and GIS Analysts at Northern Arizona University are creating detailed linkage designs for 16 priority areas highlighted in the Wildlife Linkages Assesment. These plans identify and map multi-species corridors that will best maintain wildlife movement between wildland blocks, as well as highlight specific planning and road mitigation measures required to maintain connectivity in these corridors. Note: The linkage design reports are in compressed PDF format for faster download. Unfortunately, the compression occasionally makes small text on maps within the report difficult to read. If you would like a high-resolution PDF or PNG copy of any...

The purpose of this Integrated Natural Resources Plan (INRMP) is to guide and document the manner in which the U.S. Army Yuma Proving Ground (USAYPG or YPG) sutains the military mission on the installation while managing the ecological health of our natural resources area. The INRMP will ensure sound land management, environmental stewardship, and compliance with all relevant laws, regulations, and applicable state and federal management plans, are consider during mission and project planning activities and that no net loss of mission capacity results from meeting our stewardship responsibilities. The INRMP is consistent with military requirements and the Sikes Act and associated amendments. Management of natural...

The human footprint map focuses on shrubland ecosystems and combines models of habitat use by synanthropic predators (“top-down” effects) and the risk of invasive plant presence (“bottom-up” effects) to estimate the total influence of human activities. Humans have dramatically altered wildlands in the western United States over the past 100 years by using these lands and the resources they provide. Anthropogenic changes to the landscape, such as urban expansion, construction of roads, power lines, and other networks and land uses necessary to maintain human populations influence the number and kinds of plants and wildlife that remain. We developed the map of the human footprint for the western United States from...

Saltcedar (Tamarix spp.) is an exotic, invasive shrub of riparian corridors in the western United States that can promote soil salinization via leaf exudates as Tamarix litter accumulates on the soil surface. Tamarix stands occur in association with big sagebrush (Artemisia tridentata), greasewood (Sarcobatus vermiculatus), and cottonwood (Populus deltoides) in northern Wyoming, depending on topographic position. Revegetation of Tamarix-invaded sites can be limited by altered soil conditions. Tamarix stands in northcentral Wyoming were selected to determine the relationship of Tamarix shrubs and associated vegetation to soil salinity, pH, and nutrients. In general, salinity of surface soils (0?5 cm) was greater...

To map the baseline distribution of riparian forest and shrublands, we all included LANDFIRE Existing Vegetation Types (EVT) where the type contained the word "riparian", "woodland", "ravine" and "swamp". We also included aspen woodlands at elevations below 1524 m using ReGAP values, as these areas, upon inspection were found to be introduced vegetation and not aspen. These data are provided by Bureau of Land Management (BLM) "as is" and may contain errors or omissions. The User assumes the entire risk associated with its use of these data and bears all responsibility in determining whether these data are fit for the User's intended use. These data may not have the accuracy, resolution, completeness, timeliness,...
Alternatives to chemicals for controlling dreissenid mussels are desirable for environmental compatibility, but few alternatives exist. Previous studies have evaluated the use of electrified fields for stunning and/or killing planktonic life stages of dreissenid mussels, however, the available literature on the use of electrified fields to control adult dreissenid mussels is limited. We evaluated the effects of sinusoidal alternating current (AC) and square- wave pulse direct current (PDC) exposure on the survival of zebra mussels at water temperatures of 10, 15, and 22°C. Peak voltage gradients of ~ 17 and 30 Vp/cm in the AC and PDC exposures, respectively, were continuously applied for 24, 48, or 72 h. Peak power...

This study evaluated carbon dioxide (CO2) injected into water as a possible behavioral stimulant to enhance capture and removal of invasive red swamp crayfish (RSC, Procambarus clarkii Girard, 1852) from a retention pond in southeastern Michigan. Objectives of this study were to (1) determine if target CO2 concentrations were attainable within the infested pond, and (2) determine if CO2 treatment was effective to push RSC towards shorelines or onto dry land where they could be collected and removed. Carbon dioxide was applied directly into one treatment pond (~2,500 m3) in Novi, MI. Two nearby ponds in Livonia, MI were used as untreated control ponds. Crayfish removal efficiency was evaluated in all ponds using...

Many amenity-rich regions are experiencing rapid land-use change in the form of low-density residential development. This widespread land-use change, exurbanization, has profound implications for regional biological diversity and ecosystem function. In the United States, exurban land use occupies seven times more area than land with urban and suburban densities, and has increased at a rate of about 10 to 15% per year. Drivers of exurbanization include technological advancements and increases in tele-commuting, transportation and road-network improvements, and various push- (crime, crowding, poor education systems, etc.) and pull- (affordable or desirable housing, privacy, better schools, etc.) factors. The rapid...

The REA estimates the condition of 14.2 million acres of land in southern New Mexico. It is based on states described in “ecological site descriptions” (ESDs) and expert knowledge. ESDs have been developed by the Natural Resource Conservation Service, and they are a consistent, science and expert-based resource increasingly used by land managers. It focuses on public rangelands - grasslands, shrublands, and savannas - managed by the Bureau of Land Management, and includes some other lands as well. The REA compares current condition to the expected or “reference” condition, and summarizes the vegetation, ecological processes and restorative management options of these states. Depending on these management options...

Abstract: Topock Marsh is a large wetland adjacent to the Colorado River and the main feature of Havasu National Wildlife Refuge (Havasu NWR) in southern Arizona. In 2010, the U.S. Fish and Wildlife Service (FWS) and Bureau of Reclamation began a project to improve water management capabilities at Topock Marsh and protect habitats and species. Initial construction required a drawdown, which caused below-average inflows and water depths in 2010–11. U.S. Geological Survey Fort Collins Science Center (FORT) scientists collected an assemblage of biotic, abiotic, and hydrologic data from Topock Marsh during the drawdown and immediately after, thus obtaining valuable information needed by FWS. Building upon that work,...
