Sky Island Grassland Assessment: Identifying and Evaluating Priority Grassland Landscapes for Conservation and Restoration in the Borderlands
Sky Island Grassland Assessment: Identifying and Evaluating Priority Grassland Landscapes for Conservation and Restoration in the Borderlands David Gori, Gitanjali S. Bodner, Karla Sartor, Peter Warren and Steven Bassett September 2012 Animas Valley, New Mexico Photo: TNC Preferred Citation: Gori, D., G. S. Bodner, K. Sartor, P. Warren, and S. Bassett. 2012. Sky Island Grassland Assessment: Identifying and Evaluating Priority Grassland Landscapes for Conservation and Restoration in the Borderlands. Report prepared by The Nature Conservancy in New Mexico and Arizona. 85 p. i Executive Summary Sky Island grasslands of central and southern Arizona, southern New Mexico and northern Mexico form the “grassland seas” that surround small forested mountain ranges in the borderlands. Their unique biogeographical setting and the ecological gradients associated with “Sky Island mountains” add tremendous floral and faunal diversity to these grasslands and the region as a whole. Sky Island grasslands have undergone dramatic vegetation changes over the last 130 years including encroachment by shrubs, loss of perennial grass cover and spread of non-native species. Changes in grassland composition and structure have not occurred uniformly across the region and they are dynamic and ongoing. In 2009, The National Fish and Wildlife Foundation (NFWF) launched its Sky Island Grassland Initiative, a 10-year plan to protect and restore grasslands and embedded wetland and riparian habitats in the Sky Island region. The objective of this assessment is to identify a network of priority grassland landscapes where investment by the Foundation and others will yield the greatest returns in terms of restoring grassland health and recovering target wildlife species across the region. -
North American Deserts Chihuahuan - Great Basin Desert - Sonoran – Mojave
North American Deserts Chihuahuan - Great Basin Desert - Sonoran – Mojave http://www.desertusa.com/desert.html In most modern classifications, the deserts of the United States and northern Mexico are grouped into four distinct categories. These distinctions are made on the basis of floristic composition and distribution -- the species of plants growing in a particular desert region. Plant communities, in turn, are determined by the geologic history of a region, the soil and mineral conditions, the elevation and the patterns of precipitation. Three of these deserts -- the Chihuahuan, the Sonoran and the Mojave -- are called "hot deserts," because of their high temperatures during the long summer and because the evolutionary affinities of their plant life are largely with the subtropical plant communities to the south. The Great Basin Desert is called a "cold desert" because it is generally cooler and its dominant plant life is not subtropical in origin. Chihuahuan Desert: A small area of southeastern New Mexico and extreme western Texas, extending south into a vast area of Mexico. Great Basin Desert: The northern three-quarters of Nevada, western and southern Utah, to the southern third of Idaho and the southeastern corner of Oregon. According to some, it also includes small portions of western Colorado and southwestern Wyoming. Bordered on the south by the Mojave and Sonoran Deserts. Mojave Desert: A portion of southern Nevada, extreme southwestern Utah and of eastern California, north of the Sonoran Desert. Sonoran Desert: A relatively small region of extreme south-central California and most of the southern half of Arizona, east to almost the New Mexico line. -

BIRDS of the TRANS-PECOS a Field Checklist
TEXAS PARKS AND WILDLIFE BIRDS of the TRANS-PECOS a field checklist Black-throated Sparrow by Kelly B. Bryan Birds of the Trans-Pecos: a field checklist the chihuahuan desert Traditionally thought of as a treeless desert wasteland, a land of nothing more than cacti, tumbleweeds, jackrabbits and rattlesnakes – West Texas is far from it. The Chihuahuan Desert region of the state, better known as the Trans-Pecos of Texas (Fig. 1), is arguably the most diverse region in Texas. A variety of habitats ranging from, but not limited to, sanddunes, desert-scrub, arid canyons, oak-juniper woodlands, lush riparian woodlands, plateau grasslands, cienegas (desert springs), pinyon-juniper woodlands, pine-oak woodlands and montane evergreen forests contribute to a diverse and complex avifauna. As much as any other factor, elevation influences and dictates habitat and thus, bird occurrence. Elevations range from the highest point in Texas at 8,749 ft. (Guadalupe Peak) to under 1,000 ft. (below Del Rio). Amazingly, 106 peaks in the region are over 7,000 ft. in elevation; 20 are over 8,000 ft. high. These montane islands contain some of the most unique components of Texas’ avifauna. As a rule, human population in the region is relatively low and habitat quality remains good to excellent; habitat types that have been altered the most in modern times include riparian corridors and cienegas. Figure 1: Coverage area is indicated by the shaded area. This checklist covers all of the area west of the Pecos River and a corridor to the east of the Pecos River that contains areas of Chihuahuan Desert habitat types. -

Animal Biodiversity and Conservation, 42.1: 127–134, Doi: https://doi.org/10.32800/abc.2019.42.0127 Abstract First insights into the fecal bacterial microbiota of the black–tailed prairie dog (Cynomys ludovicianus) in Janos, Mexico. Intestinal bacteria are an important indicator of the health of their host. Incorporating periodic assess- ment of the taxonomic composition of these microorganisms into management and conservation plans can be a valuable tool to detect changes that may jeopardize the survival of threatened populations. Here we describe the diversity and abundance of fecal bacteria for the black–tailed prairie dog (Cynomys ludovicianus), a threat- ened species, in the Janos Biosphere Reserve, Chihuahua, Mexico. We analyzed fecal samples through next generation massive sequencing and amplified the V3–V4 region of the 16S rRNA gene using Illumina technology. The results were analyzed with QIIME based on the EzBioCloud reference. We identified 12 phyla, 22 classes, 33 orders, 54 families and 263 genera. -
Prairie Dog Decline Reduces the Supply of Ecosystem Services and Leads to Desertification of Semiarid Grasslands
Prairie Dog Decline Reduces the Supply of Ecosystem Services and Leads to Desertification of Semiarid Grasslands Lourdes Martı´nez-Este´vez1*, Patricia Balvanera2,3,4, Jesu´ s Pacheco1, Gerardo Ceballos1 1 Instituto de Ecologı´a, Universidad Nacional Auto´noma de Me´xico, Me´xico, Me´xico, 2 Centro de Investigaciones en Ecosistemas, Universidad Nacional Auto´noma de Me´xico, Michoaca´n, Me´xico, 3 Department of Biology, Stanford University, Stanford, California, United States of America, 4 Department of Ecology, Evolution, and Environmental Biology, Columbia University New York, New York, United States of America Abstract Anthropogenic impacts on North American grasslands, a highly endangered ecosystem, have led to declines of prairie dogs, a keystone species, over 98% of their historical range. While impacts of this loss on maintenance of grassland biodiversity have been widely documented, much less is known about the consequences on the supply of ecosystem services. Here we assessed the effect of prairie dogs in the supply of five ecosystem services by comparing grasslands currently occupied by prairie dogs, grasslands devoid of prairie dogs, and areas that used to be occupied by prairie dogs that are currently dominated by mesquite scrub. Groundwater recharge, regulation of soil erosion, regulation of soil productive potential, soil carbon storage and forage availability were consistently quantitatively or qualitatively higher in prairie dog grasslands relative to grasslands or mesquite scrub. Our findings indicate a severe loss of ecosystem services associated to the absence of prairie dogs. These findings suggest that contrary to a much publicize perception, especially in the US, prairie dogs are fundamental in maintaining grasslands and their decline have strong negative impacts in human well – being through the loss of ecosystem services. -

National Fish and Wildlife Foundation Draft Business Plan for the Sky Island Grasslands March 24, 2009
National Fish and Wildlife Foundation Draft Business Plan for the Sky Island Grasslands March 24, 2009 NFWF Sky Island Grass Biz Plan.indd 1 8/12/09 1:28:50 PM What Is a Business Plan? A business plan serves two broad, primary functions. First, it provides specific information to those (e.g., prospective investors) not familiar with the proposed or existing business, including its goals and the management strategy and financial and other resources necessary to attain those goals. Second, a business plan provides internal guidance to those who are active in the operation of the business, allowing all individuals to understand where the business is headed and the means by which it will get there. The plan helps keep the business from drifting away from its goals and key actions through careful articulation of a strategy. In the context of the National Fish and Wildlife Foundation’s conservation efforts, business plans represent the strategies necessary to meet the conservation goals of Keystone and other initia- tives. Each business plan emphasizes the type(s) and magnitude of the benefits that will be realized through the initiative, the monetary costs involved, and the potential obstacles (risks) to achieving those gains. Each of the Foundation’s business plans has three core elements: Conservation Outcomes: A concrete description of the outcomes to which the Foundation and grantees will hold ourselves accountable. Implementation Plan with Strategic Priorities and Performance Measures: A description of the specific strategies that are needed to achieve our conservation outcome and the quantitative measures by which we will measure success and make it possible to adaptively revise strategies in the face of underperformance.
