Status and Distribution of Chihuahuan Desert Grasslands in the United States and Mexico Grasslands comprise a small part of the Chihuahuan Desert but are vital to the biological diversity of the ecoregion. Characteristic grasses of the Chihuahuan Desert are tobosa (Pleuraphis mutica) and black grama (Bouteloua eriopoda) but other common species include alakali sacaton (Sporobolus airoides), big alkali sacaton (S. wrightii), mesa dropseed (S. flexuosus), blue grama (B. gracilis), sideoats grama (B. curtipendula ), hairy grama (B. hirsuta), slender grama (B. filiformis), chino grama (B. brevista), spruce top grama (B. chondrosioides), bush muhly (Muhlenbergia porteri), several three awns (Aristida spp.), and fluff grass (Dasyochloa pulchela) (Johnson 1974, Dinerstein et al. 2000).

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...

Congress mandated each state and territory to develop a Comprehensive Wildlife Conservation Strategy (now named Wildlife Action Plans) by 2005 in order to continue to receive federal funds through the SWG program. Nevada’s Wildlife Action Plan (WAP) was completed and approved by the U.S. Fish and Wildlife Service (USFWS) in 2005. Nevada’s WAP has served as a plan of action for state wildlife conservation and funding by targeting the species of greatest conservation need and the key habitats on which they depend.

Attempts to evaluate current ecological conditions suggest that approximately two thirds of these remain as intact or restorable grassland habitat. These grasslands provide watershed services such as flood control and aquifer recharge across the region, and continue to support dozens of species of concern. Prioritizing conservation interventions for these remaining grassland blocks has been challenging. Reliable data on condition and conservation value of grasslands in the region have not been systematically summarized. State and national boundaries further complicate...

El muro fronterizo ha fragmentado los ecosistemas presentes en la región, pudiendo influir en la pérdida de la conectividad de poblaciones de fauna silvestre entre ambos países. Ante tal situación nuestro objetivo fue identificar las áreas más importantes de conectividad para 19 especies que se distribuyen en la franja fronteriza dentro de los estados de Sonora y Chihuahua y los principales impactos que puede tener la estructura asociada a la frontera.

Sacaton stands that remain provide key resources for watershed function, wildlife, and livestock—yet may need special management to sustain these benefits. This report describes mapping methods and management recommendations that can be applied to riparian grasslands throughout the region. By examining sacaton grasslands in the Las Cienegas National Conservation Area, this project also refines methods for evaluating ecological condition, and provides managers at this site with detailed maps of both high-quality habitat and restoration needs.

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...

Annual oil production data were incrementally summed to construct a logistic curve in its initial phase. Using a curve-fitting approach, a population-growth logistic function was applied to complete the cumulative production curve. The simulated curve was then deconstructed into a set of annual oil production data producing an “idealized” Hubbert curve. An idealized Hubbert curve (IHC) is defined as having properties of production data resulting from a constant growth-rate under fixed resource limits. An IHC represents a potential production curve constructed from cumulative production...

The work in the 1990s did not include Arkansas or Florida. None of the previous reports included Alaska because it is stored in a separate database (Alaska Land Information System) and is in a different format. This report includes data for all states for which there are Federal mining claim records, beginning in 1976 and continuing to 2010, except Alaska, which only had data to 2007. The statistics compiled from the databases are counts of the number of active mining claims in a section of land each year from 1976...

Ello se ha debido principalmente deficientes prácticas ganaderas, al cambio climático, la supresión del fuego, a la fragmentación de hábitat y cambio de uso de suelo. En conjunto, se ha provocado un incremento en los escurrimientos y la erosión, una disminución de la diversidad biológica y pérdida en las concentraciones de aves, incremento en la invasión de especies no nativas y una disminución en la cantidad de forraje para animales domésticos y silvestres. La Estrategia para la Conservación de los Pastizales de Desierto Chihuahuense (ECOPAD) ofrece un esquema de cooperación para enfrentar...

The objective of this project was to use a science-based approach to identify a network of Conservation Sites throughout the Ecoregion that, with proper management, would ensure the long-term persistence of the Ecoregion's biodiversity, including rare and common species, native vegetation communities, and the ecological processes needed to maintain these elements of biodiversity.

SGCN include terrestrial, freshwater, and marine birds, mammals, reptiles, amphibians, invertebrates, fishes, plants and plant communities. The goal of the plan is ultimately to conserve and improve the status of these species and, as possible, prevent listings under the Endangered Species Act. The Conservation Action Plan has elements for anyone interested in conservation in Texas.
