Werdon. for U.S. Fish and Wildlife Service Region 1 Portland, Oregon - M~&~aei J. Spear Approved: Date: 4~ /6 4 This Recovery Plan covers one federally listed species (Moapa dace) and seven species ofspecial concern in the Muddy River ecosystem. DISCLAIMER Recovery plans delineate reasonable actions believed to be required to recover and/or protect listed species. Plans published by the U.S. Fish and Wildlife Service or National Marine Fisheries Service are sometimes prepared with the assistance of recovery teams, contractors, State agencies, and other affected and interested parties. Recovery teams serve as independent advisors to the Services. Plans are reviewed by the public and submitted to additional peer review before they are adopted by the Services. Objectives of the plan will be attained and any necessary funds made available subject to budgetary and other constraints affecting the parties involved, as well as the need to address other priorities. Recovery plans do not obligate other parties to undertake specific tasks and may not represent the views nor the official positions or approval ofany individuals or agencies involved in the plan formulation, other thanthe U.S. Fish and Wildlife Service/National Marine Fisheries Service. They represent the official position ofthe National Marine Fisheries Service! U.S. Fish and Wildlife Service only after they have been signed by the Assistant Administrator/Regional Director or Director as approved. Approved recovery plans are subject to modification as dictated by new findings, changes in species status, and the completion ofrecovery tasks. By approving this document, the Director/Regional Director/Assistant Administrator certifies that the dataused in its development represents the best scientific and commercial data available at the time it was written. Copies ofall documents reviewed in development ofthe plan are available in the administrative record, located at the Nevada State Office ofthe U.S. Fish and Wildlife Service, Reno, Nevada.

EXECUTIVE SUMMARY OF THE RECOVERY PLAN FOR TILE RARE AQUATIC SPECIES OF THE MUDDY RIVER ECOSYSTEM Current Species Status: The Moapa dace (Moapa coriacea) was listed as endangered on March 11, 1967 (32 Federal ~.gisi~r 4001). It occupies approximately 9.5 kilometers (6 miles) of stream habitat in five thermal headwater spring systems and the main stem of the upper Muddy (= Moapa) River, Clark County, Nevada. Critical habitat has not been designated. A range-wide survey documented 3,841 adult Moapa dace in August 1994. The Muddy River ecosystem is also inhabited by seven aquatic species of special concern (three fish, two snails, and two insects). Habitat Requirements and Limiting Factors: Adult Moapa dace inhabit the main stem Muddy River, but only successfully reproduce in tributary thermal spring outflows (30~32o Celsius; 86~89.6o Fahrenheit). Larval and juvenile dace occur in low- to moderate-velocity areas in the spring outflows. Moapa dace are omnivorous drift feeders. Principle threats to the species are habitat alterations which have eliminated access to and/or destroyed spawning, nursery, and foraging areas; water loss; impoundments; and introductions of nonnative fishes and parasites. Recovery Objective: Delisting. Recovery Criteria: Moapa dace willbe considered for reclassification from endangered to threatened when: 1) Existing instream flows and historical habitat in three of the five occupied spring systems (Apcar, Baldwin, Cardy Lamb, Muddy Spring, Refuge) and the upper Muddy River have been protected through conservation agreements, easements, or fee title acquisitions; 2) 4,500 adult Moapa dace are present among the five spring systems and the upper Muddy River; and 3) the Moapa dace population is comprised of three or more age- classes, and reproduction and recruitment are documented from three spring systems. Moapa dace will be considered for delisting provided that all reclassification criteria have been met and when: 1) 6,000 adult Moapa dace are present among the five spring systems and the upper Muddy River for 5 consecutive years; 2) 75 percent ofthe historical habitat in the five spring systems and the upper Muddy River provides Moapa dace spawning, nursery, cover, and/or foraging habitat; and 3) nonnative fishes and parasites no longer adversely affect the long-term survival ofMoapa dace. These recovery criteria are preliminary and may be revised on the basis of new information (including research specified as recovery tasks). ii Actions Needed 1. Protect instream flows and historical habitat within the upper Muddy River and tributary spring systems. 2. Conduct restoration/management activities. 3. Monitor Moapa dace population. 4. Research population health. 5. Provide public information and education. Implementation Participants The Nevada Division ofWildlife and National Biological Service will be assisting the U.S. Fish and Wildlife Service in implementing recovery tasks. For activities occurring on private land, landowner participation is also needed.

Brief Overview The Muddy ( Moapa) River is located in northeastern Clark County, Nevada (Figure 1). The river originates from numerous thermal springs [30~32o Celsius (0C), 86~89.6oFahrenheit (0F)] in an area known as Warm Springs. Historically, the river flowed 48.4 kilometers (kin) [30 miles (mi)] into the Virgin River, a Colorado River tributary. However, when Hoover Dam was completed in 1935, the lower 8 km (5 mi) ofthe Muddy River were subsequently flooded by Lake Mead. The remaining riverine habitat has an average gradient of 1.6 meters (in) per kilometer [8.45 feet (ft) per mile] (Cross 1976). Total discharge from the headwater springs is nearly constant at approximately 1.3 cubic meters per second (m3/sec) [45.9 cubic feet per second (cfs)] (Eakin 1964). However, flow in the main stemMuddy River varies with precipitation events, seasonal water diversions, groundwater recharge, vegetation transpiration, evaporation, and inigation return flows. Before reaching Lake Mead, nearly 75 percent ofthe annual inflow is lost to diversions, evaporation, and transpiration [Soil Conservation Service (SCS) 1993]. Streams in the Moapa Valley were originally bordered by willow (Salix spp.) and screwbean mesquite (Prosopispubescens) (Longwell 1928, Harrington 1929). However, normative palm trees are now the dominant riparian tree species along spring systems in the Warm Springs area, and they are increasing in abundance along the upper Muddy River. Salt cedar (Tamarix spp.), another nonnative species, is culTently the most common riparian species along the middle and lower river. The Muddy River ecosystem supports eight rare, endemic aquatic species, 1 V Meadow Valley Wash NVAZ N o km4 20 0 mi 12.4 •Las Vegas Hoover Colorado Dam River Figure 1. Geographic location of the Muddy River and The Warm Springs area, Clark Counly, Nevada. 2 including one endangered fish. The Moapa dace (Moapa coriacea) was federally listed as endangered under the Endangered Species Preservation Act of 1966 on March 11, 1967 (32 Federal Register 4001), and has been afforded the protection of the Endangered Species Act (ESA) since its inception in 1973. The U.S. Fish and Wildlife Service (USFWS) assigned Moapa dace a recovery priority of 1 [each listed species is ranked from 1 (highest) to 12] because it is the only species within the genus Moapa, there is a high degree ofthreat to its continued existence, and it has a high potential forrecovery.

  • 2005 Wildlife Action Plan: Terrestrial Nongame Birds, Mammals, and Reptiles
    APPENDIX D IDENTIFICATION OF SPECIES OF CONSERVATION PRIORITY: DETAILED METHODS AND APPROACH 2005 Wildlife Action Plan: Terrestrial Nongame Birds, Mammals, and Reptiles Methods The Species of Conservation Priority identification process began in July, 2002. After initially gathering input from partner land management agency personnel at the field level, a Species Priority Matrix was developed using standard species conservation prioritization methodology (Natural Heritage Scorecard; Panjabi et al. 2001). Nevada Natural Heritage Program Species Scorecard scores were incorporated into the Species Priority Matrix. NDOW Wildlife Diversity biologists were subsequently asked to score all species of nongame birds, mammals, and reptiles using the Species Priority Matrix. The Species Priority Matrix contained the following scoring categories. 1. Endangered, Threatened, or Candidate Species Species with Endangered, Threatened, or Candidate Species status under either federal or state law were given 1 point. Total points possible in this category was 1 – multiple points for having both federal and state status were not given because state statutes are designed to generally reflect federal status. 2. Nevada Natural Heritage Program Score – Inverted Each species was given the inverted score of the Nevada Natural Heritage Program State Rank score; that is, NNHP scores run from 1 (highest risk) to 5 (lowest risk), so it was necessary to invert the score in order for “highest risk” to have the greatest arithmetic weight in the matrix. The conversion scale is illustrated in the following table. NNHP State Rank NV Species Priority Matrix Score 5 1 4 2 3 3 2 4 1 5 3. Threat The biologists were asked to assign scores to each species representing their perception of the degree of threat facing the species.

  • Endangered Species
    FEATURE: ENDANGERED SPECIES Conservation Status of Imperiled North American Freshwater and Diadromous Fishes ABSTRACT: This is the third compilation of imperiled (i.e., endangered, threatened, vulnerable) plus extinct freshwater and diadromous fishes of North America prepared by the American Fisheries Society’s Endangered Species Committee. Since the last revision in 1989, imperilment of inland fishes has increased substantially. This list includes 700 extant taxa representing 133 genera and 36 families, a 92% increase over the 364 listed in 1989. The increase reflects the addition of distinct populations, previously non-imperiled fishes, and recently described or discovered taxa. Approximately 39% of described fish species of the continent are imperiled. There are 230 vulnerable, 190 threatened, and 280 endangered extant taxa, and 61 taxa presumed extinct or extirpated from nature. Of those that were imperiled in 1989, most (89%) are the same or worse in conservation status; only 6% have improved in status, and 5% were delisted for various reasons. Habitat degradation and nonindigenous species are the main threats to at-risk fishes, many of which are restricted to small ranges. Documenting the diversity and status of rare fishes is a critical step in identifying and implementing appropriate actions necessary for their protection and management. Howard L.

(Junonia coenia on Helianthus annuus) important ecological but threatened riparian landscapes (Provencher et al. 2005). Not only does the Warm Springs Natural Area encompass the majority of Muddy River tributaries it is also the largest single tract of land in the upper Muddy River set aside for the benefit of native species in perpetuity. The prominence of water in an otherwise barren Mojave landscape provides an oasis for regional wildlife. A high bird diversity is attributed to an abundance of riparian and floodplain trees and shrubs. Contributions to plant diversity come from the Mojave Old World swallowtail (Papilio machaon) Desertsnow (Linanthus demissus) Lobe-leaved Phacelia (Phacelia crenulata) Cryptantha (Cryptantha sp.) vegetation that occur on the toe slopes of the Arrow Canyon Range from the west and the plant species occupying the floodplain where they are supported by a high water table. Several marshes and wet meadows add to the diversity of plants and animals. The thermal springs and tributaries host an abundance of aquatic species, many of which are endemic. The WSNA provides a haven for the abundant wildlife that resides permanently or seasonally and provides a significant level of protection for imperiled species.

  • Propagation of Endangered Moapa Dace
    Copeia 106, No. 4, 2018, 652–662 Propagation of Endangered Moapa Dace Jack E. Ruggirello1,4, Scott A. Bonar2, Olin G. Feuerbacher1, Lee H. Simons3,4, and Chelsea Powers1 We report successful captive spawning and rearing of the highly endangered Moapa Dace, Moapa coriacea (approximately 650 individual fish in existence at time of this study). We simulated conditions under which this stream-dwelling southern Nevada cyprinid and similar species spawned and reared in the wild by varying temperature, photoperiod, flow, and substrate in 14 different spawning and rearing treatments in a propagation facility. Successful spawning occurred in artificial streams with the following characteristics: water flow directed both across the bottom gravel substrate into a cobble bed and across the upper water column; 12–14 fish/stream (0.016–0.026 fish/L depending on water level); static water temperature of 30–328C; photoperiod of 12 h light and 12 h dark; gradual replacement of water from their natal stream with on-site well water; a combination of pelleted, frozen and live food; and minimal disturbance of fish. Nevada Department of Wildlife now uses these techniques successfully to produce fish in a culture setting. Identification of the effective combination of factors to trigger spawning in exceptionally rare fishes can be difficult and time consuming, and limiting factors can be subtle. Sufficient numbers of available test fish, close study and replication of wild spawning conditions, careful documentation, and patience to identify subtle limiting factors are often required to effectively rear and spawn fishes not previously propagated. PAWNING and rearing endangered species in captivity Ourobjectivewastouseinformationobtainedfrom can be a powerful tool in the preservation of spawning observations of Moapa Dace in the wild (e.g., S evolutionarily important populations (Johnston, Ruggirello, 2014; Ruggirello et al., 2015) and methods used to 1999).

HEREFORD entitled Population genetics and population dynamics of Moapa dace be accepted in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE Mary M. Peacock, Ph.D., Advisor Guy A. Hoelzer, Ph.D., Committee Member James S. Sedinger, Ph.D., Graduate School Representative David W. Zeh, Ph.D., Dean, Graduate School i ABSTRACT The Mojave Desert is an arid environment where precipitation ranges from 3.4 to 31.0 cm of rain per year. Species adapted to live in the Mojave Desert tend to be drought resistant and typically utilize little water. Geothermal springs are scare but provide consistent dependable water resources from large carbonaceous aquifers. Springs in the Mojave Desert were manipulated by human populations for agriculture, recreation, or municipalities. As a result, aquatic ecosystems and aquatic species were disrupted on many levels. For example, habitat fragmentation limited movement and dispersal of organisms; population isolation constrained meta-population dynamics and gene flow, and non-native species disrupted food webs, trophic interactions, and displaced native species. As water demands continue to increase in Southern Nevada, aquatic ecosystems are at greater risk and need to be carefully managed. Endangered species risk losing genetic variation and evolutionary potential when habitat is fragmented, limited, or both.
