Area: (in hectares) The total area of the Roswell Artesian Wetlands is 917hectares. There are 877 hectares of wetlands on the Bitter Lake National Wildlife Refuge and 40 hectares of wetlands on the Bottomless Lakes State Park. The total area of Bitter Lake National Refuge total area (Middle Tract) is 4,585 hectares and the total area of Bottomless Lakes State Park is approximately 500 hectares. Information Sheet on Ramsar Wetlands (RIS), page 4 12. General overview of the site: Provide a short paragraph giving a summary description of the principal ecological characteristics and importance of the wetland. The Roswell Artesian Wetlands are situated along the Pecos River but are largely fed by natural groundwater discharge from the Roswell Basin that forms a series of springs, seeps and sinkhole lakes at Bitter Lakes National Wildlife Refuge and at Bottomless Lakes State Park east of Roswell, New Mexico. These groundwater discharges form extensive saltgrass marshes, iodine bush flats, sacaton flats, and cattail and bulrush marsh communities. These wetlands provide significant habitat for a diverse assemblage of plants and animals including several endemic species as well as many waterfowl, wading birds and migratory songbirds. Notably, these wetlands are home to one of the largest collections of dragonflies and damselflies in the world (over 100 species). These springs, sinkhole lakes, creeks and wetlands are an exceptional resource for recreation, education and research and they play an important role in the hydrology of the Pecos River as well as are important economically for the communities of Chavez County and the surrounding areas in New Mexico, USA. 13. Ramsar Criteria: Tick the box under each Criterion applied to the designation of the Ramsar site. See Annex II of the Explanatory Notes and Guidelines for the Criteria and guidelines for their application (adopted by Resolution VII.11). All Criteria which apply should be ticked. 1 • 2 • 3 • 4 • 5 • 6 • 7 8 • 9 14. Justification for the application of each Criterion listed in 13 above: Criterion 1: A wetland should be considered internationally important if it contains a representative, rare, or unique example of a natural or near-natural wetland type found within the appropriate biogeographic region. Substantial natural subterranean groundwater discharge occurs at the Roswell Artesian Wetlands (Bitter Lakes National Wildlife Refuge and Bottomless Lakes State Park) as manifested by a number of springs, seeps, extensive wetlands, and sinkholes formed in the gypsum bedrock of the karst terrain . The Roswell Artesian Wetlands contain unique examples of small-to-large, deep, round, steep-sided sinkholes (also known as “collapse dolines” or cenotes ) that are fed by artesian groundwater. These sinkhole lakes were formed by solution of gypsum- and limestone- bearing rocks resulting in caverns and collapsed domed roofs that are accessible from the surface (Land 2003). Water discharging from springs, seeps and sinkholes is brackish to saline, with high sulfate, chloride, and total ion concentrations. Additionally, permanent rivers/streams/creeks including the floodplain of the Pecos River and permanent saline/brackish/alkaline lakes occur on the Roswell Artesian Wetlands providing a critical source of water and habitats to a variety of plants and animals of the Chihuahuan Desert. Information Sheet on Ramsar Wetlands (RIS), page 5 Criterion 2: A wetland should be considered internationally important if it supports vulnerable, endangered, or critically endangered species or threatened ecological communities . Quality of the brackish water varies, but several sinkhole lakes and springs support unique native fish and invertebrate communities including Roswell springsnail ( Pyrgulopsis roswellensis ), Koster's springsnail ( Juturnia kosteri ), and Noel's amphipod ( Gammarus desperatus ), which represent relict species once associated with the Permian seas that once covered this area. These 2 molluscs and a crustacean are federally-listed as endangered and are found no where else in the world. These invertebrates have only recently been described. Noel's amphipod was described as a new species in 1981 (Cole, 1981), whereas Roswell springsnail and Koster's springsnail were described as new species in 1987 (Taylor, 1987). The snails are in the family Hydrobiidae and are small, barely visible to the naked eye. Roswell springsnail and Koster’s springsnail are light tan colored with shell lengths ranging from 2.5 to 4.5 mm (0.1 to 0.2 inches) and shells have four to five moderately convex whorls (Hershler 1994). Noel's amphipod is greenish-brown colored, with bands of red on the sides of the body.

  • Abstract Effects of Wildfire on Water Quality and Benthic Macroinvertebrate Communities of a Chihuahuan Desert Spring System
    ABSTRACT EFFECTS OF WILDFIRE ON WATER QUALITY AND BENTHIC MACROINVERTEBRATE COMMUNITIES OF A CHIHUAHUAN DESERT SPRING SYSTEM by Tara Jo Haan Wildfire disturbances affect resource availability and alter community composition in arid environments. Traditionally, fire effects on arid-land aquatic ecosystems are under-studied compared to terrestrial ecosystems. Chihuahuan Desert spring systems offer a unique opportunity to study such effects on macroinvertebrate community resistance and resilience. I took advantage of a rare opportunity to employ a BACI design to observe changes in water quality and macroinvertebrate communities to wildfire in a spring system on Bitter Lake National Wildlife Refuge, New Mexico. The results suggest significant water quality and species-specific response to wildfire. I observed an increase in an endangered snail, Juturnia kosteri, but there were no significant community-based changes. These results suggest that arid-land aquatic communities can be resistant to abiotic/biotic changes caused by wildland fire. With climate change predicted to increase the frequency and intensity of arid-land fires, aquatic communities may be more vulnerable to severe events in the future.

  • Crustacea: Amphipoda) in Texas and New Mexico, Usa
    ANALYSIS OF THE GAMMARUS-PECOS COMPLEX (CRUSTACEA: AMPHIPODA) IN TEXAS AND NEW MEXICO, USA GERALD A. COLE Route 4, Box 892 Flagstaff, Arizona 86001 ABSTRACT A comparative study was made of representatives from seven populations of Gammarus in Texan and New Mexican fresh-to-miohaline waters in areas once overlain by Permian seas. They included the described species: G. pecos Cole and Bousfield (symbolized P) from Pecos Co., TX; G. hyalelloides Cole (H) from Phantom Lake Spring, Jeff Davis Co., TX; and G. desperatus Cole (D) from Chaves Co., NM. Members of other populations were examined from: San Solomon Spring (S), Toyahvale, Reeves Co., TX; a large species (C) co-occurring with H in Phantom Lake Spring; a small form (M) that came either from Phantom Lake Spring or from a spring 350 m to the north; and a species (E) from a pool near Carlsbad, Eddy Co., NM. All members of the group lack calceoli, bear C-setae on their mandibular palps, and have narrow oostegites. Coxae 1-4, in the larger individuals, are armed abundantly with long setae, and all animals have at least one spine at the posterodistal corner of the first peduncular article of the antennule. Twenty Mann-Whitney U tests were applied to certain morphologic attributes of the seven populations. The results suggest that: P and S are conspecific, with the latter showing some affinities to the larger animals (C) in the nearby Phantom Lake Spring system; C probably is a new species although more closely related to M and H than are the other four; G.

  • Arizona Wildlife Notebook
    ARIZONA WILDLIFE CONSERVATION ARIZONA WILDLIFE NOTEBOOK GARRY ROGERS Praise for Arizona Wildlife Notebook “Arizona Wildlife Notebook” by Garry Rogers is a comprehensive checklist of wildlife species existing in the State of Arizona. This notebook provides a brief description for each of eleven (11) groups of wildlife, conservation status of all extant species within that group in Arizona, alphabetical listing of species by common name, scientific names, and room for notes. “The Notebook is a statewide checklist, intended for use by wildlife watchers all over the state. As various individuals keep track of their personal observations of wildlife in their specific locality, the result will be a more selective checklist specific to that locale. Such information would be vitally useful to the State Wildlife Conservation Department, as well as to other local agencies and private wildlife watching groups. “This is a very well-documented snapshot of the status of wildlife species – from bugs to bats – in the State of Arizona. Much of it should be relevant to neighboring states, as well, with a bit of fine-tuning to accommodate additions and deletions to the list. “As a retired Wildlife Biologist, I have to say Rogers’ book is perhaps the simplest to understand, yet most comprehensive in terms of factual information, that I have ever had occasion to peruse. This book should become the default checklist for Arizona’s various state, federal and local conservation agencies, and the basis for developing accurate local inventories by private enthusiasts as well as public agencies. "Arizona Wildlife Notebook" provides a superb starting point for neighboring states who may wish to emulate Garry Rogers’ excellent handiwork.

SGMA seeks to achieve sustainability, which is defined as the absence of several undesirable results, including “depletions of interconnected surface water that have significant and unreasonable adverse impacts on beneficial users of surface water” (Water Code §10721). The Nature Conservancy (TNC) is a science-based, nonprofit organization with a mission to conserve the lands and waters on which all life depends. Like humans, plants and animals often rely on groundwater for survival, which is why TNC helped develop, and is now helping to implement, SGMA. Earlier this year, we launched the Groundwater Resource Hub, which is an online resource intended to help make it easier and cheaper to address environmental requirements under SGMA. As a first step in addressing when depletions might have an adverse impact, The Nature Conservancy recommends identifying the beneficial users of surface water, which include environmental users. This is a critical step, as it is impossible to define “significant and unreasonable adverse impacts” without knowing what is being impacted. To make this easy, we are providing this letter and the accompanying documents as the best available science on the freshwater species within the boundary of your groundwater sustainability agency (GSA).

  • Rapid Colonization by Dragonflies in a New Effluent-Dependent
    If you build it, they will come: rapid colonization by dragonflies in a new effluent-dependent river reach Michael T. Bogan1, Drew Eppehimer1, Hamdhani Hamdhani1,2 and Kelsey Hollien1 1 School of Natural Resources and the Environment, University of Arizona, Tucson, AZ, USA 2 Department of Aquatic Resources Management, University of Mulawarman, Samarinda, Indonesia ABSTRACT Background: Aquatic ecosystems are greatly altered by urban development, including the complete loss of natural habitat due to water diversions or channel burial. However, novel freshwater habitats also are created in cities, such as effluent-dependent streams that rely on treated wastewater for flow. It is unclear how diverse these novel ecosystems are, or how quickly aquatic species are able to colonize them. In this study, we (1) quantify odonate (Insecta, Odonata) colonization of a novel effluent-dependent river reach, (2) examine how drying events affect odonates in these novel habitats, and (3) explore whether effluent-dependent streams can support diverse odonate assemblages. Methods: We conducted monthly odonate surveys at three sites along the Santa Cruz River (Tucson, AZ, USA) between June 2019 and May 2020. One site was in a long-established effluent-dependent reach (flowing since the 1970s) that served as a reference site and two sites were in a newly-established reach that began flowing on June 24, 2019 (it was previously dry). We compared odonate species richness, assemblage composition, and colonization patterns across these reaches, and examined how these factors responded to flow cessation events in the new reach. Results: Seven odonate species were observed at the study sites in the new Submitted 26 May 2020 reach within hours of flow initiation, and species rapidly continued to arrive Accepted 11 August 2020 thereafter.

  • 2020 Biological Assessment for the Rangeland Grasshopper and Mormon Cricket Suppression Program in New Mexico
    2020 Biological Assessment For the Rangeland Grasshopper and Mormon Cricket Suppression Program in New Mexico 01/24/2020 Prepared by USDA, APHIS, PPQ 270 South 17th Street Las Cruces, NM 88005 BIOLOGICAL ASSESSMENT (BA) FOR STATE CONSULTATION AND CONFERENCE FOR 2020 GH/MC PROGRAMS IN NEW MEXICO 2020 Biological Assessment for the Rangeland Grasshopper and Mormon Cricket Suppression Program, New Mexico 1.0 INTRODUCTION The Animal and Plant Health Inspection Service (APHIS), in conjunction with other Federal agencies, State departments of agriculture, land management groups, and private individuals, is planning to conduct grasshopper control programs in New Mexico in 2020. This document is intended as state-wide consultation and conference with the U.S. Fish and Wildlife Service (FWS) regarding the APHIS Rangeland Grasshopper and Mormon Cricket Suppression Program. Beginning in 1987, APHIS has consulted with the FWS on a national level for the Rangeland Grasshopper Cooperative Management Program. Biological Opinions (BO) were issued annually by FWS from 1987 through 1995 for the national program. A letter dated October 3, 1995 from FWS to APHIS concurred with buffers and other measures agreed to by APHIS for New Mexico and superseded all previous consultations.
