yuma clapper rail status

It is thought that the Yuma clapper rail was not distributed along the Colorado River until suitable habitat was created thro… Yet fish and wildlife have no legal right to water under current appropriation laws and no legitimate status as beneficiaries. Yuma clapper rails are threatened by river management activities that are detrimental to marsh formation, such as dredging, channelization, bank stabilization, and other flood control measures. Fun Facts: A group of Clapper Rails is called an “applause”, “audience”, and a “commercial” of rails. Bird species recorded here which have conservation status include: Federal T/E - Yuma Clapper Rail (presumed to nest); Arizona threatened - Least Bittern (presumed to nest), Great Egret and Snowy Egret (forages here, nests nearby), Osprey (winter), and Belted Kingfisher (winter); Arizona WatchList - Abert's … They are not applicable to species for which habitat would not be created under the LCR MSCP Conservation Plan, such as the desert tortoise, relict leopard frog, humpback chub, and threecorner milkvetch. For a complete list of all activities, please see the Research and Monitoring Activities web page. Both sexes incubate nests, typically females in the day and males at night. The extent of covered species habitat impacts that will be avoided by maintaining water deliveries to Topock Marsh are presented in Table 4-2 in the HCP. Temporary disturbance of covered species habitats, however, may be associated with habitat creation and subsequent maintenance activities (e.g., controlled burning in marshes and removal of trees to maintain succession objectives). Smaller patches are likely to support isolated nesting pairs and be within the range of habitat patch sizes used by the species for foraging and dispersal. Additional information on this species, as well as source documentation, can be found in the species accounts located at this link (PDF).The Conceptual Ecological Model (CEM) can be found here (PDF). The Cienega provides critical habitat for the four species, with estimated abundance of 405 California Black Rails, 7152 Virginia Rails, 8652 Least Bitterns and 8642 Yuma Clapper Rails. Rail, Yuma Clapper: Rallus longirostris yumanensis: Endangered: U.S.A (AZ, CA, NV) 32 FR 4001 March 11, 1967: Field Supervisor, 602-242-0210 (phone); Steve_Spangle@fws.gov (email) U.S. MRM5—Monitor selenium levels in created backwater and marsh land cover types, and study the effect of selenium released as a result of dredging activities. Yuma clapper rails are generally found in freshwater and alkali marshes dominated by stands of emergent vegetation interspersed with areas of open water and drier, upland benches. Scientific Name Common Name Status . The Yuma Clapper Rail is one of three subspecies of clapper rails in California, all of whom have been listed as endangered by State and Federal Government. Click on the arrows to expand the table. MRM1—Conduct surveys and research to better identify covered and evaluation species habitat requirements. This flightless period can occur through mid-September, and fires during this time could severely impact rails. In general, western clapper rails range from northern California along the Pacific coast to central Mexico. Clutch size ranges from 6 to 8 eggs. The presence of emergent cover, not the plant species or marsh size, is an important trait of habitat. Survey detections for the United States habitats have fluctuated between 467 and 809 individuals over the last 10 years. To the extent practicable, to avoid and minimize potential impacts on covered bird species, vegetation management activities (e.g., periodic removal of emergent vegetation to maintain canals and drains) associated with implementation of covered activities and the LCR MSCP that could result in disturbance to covered bird species will not be implemented during the breeding season to prevent injury or mortality of eggs and young birds unable to avoid these activities. This subspecies is the only population not breeding in saltwater … If feasible management methods are identified, they will be implemented. The total length for an adult clapper rail is 12.6-16.1 in (32-41 cm), with mass ranging from 5.6-14.1 oz (160-400 g). 2001). Males are larger than females, but the sexes are alike in plumage. Habitat will be created in patches as large as possible but will not be created in patches smaller than 5 acres. Jackson, J. In California, the western yellow-billed cuckoo became … Selenium is also a concern, even though it occurs naturally within the lower Colorado River Basin. Additional Yuma clapper rail habitat may be provided by marsh vegetation that becomes established along margins of the 360 acres of backwaters that will be created in Reaches 3–6. This created habitat will also provide habitat for the western least bittern and the California black rail (see conservation measures LEBI1 and BLRA1). Drying or drainage of wetlands can result in nest abandonment. yumanensis) Citation: Seasonal changes in Yuma clapper rail vocalization rate and habitat use. Created species habitats will be managed to maintain their functions as species habitat over the term of the LCR MSCP. Google Scholar In Arizona where these rails breed along the Colorado River, more than 95% of breeding evidence for the Yuma Clapper Rail (R. l. yumanensis) came from freshwater lakes, reservoirs and marshes edged with cattails and other emergent vegetation. MRM2—Monitor and adaptively manage created covered and evaluation species habitats. AMM6—Avoid or minimize impacts on covered species habitats during dredging, bank stabilization activities and other river management activities. The Yuma clapper rail is largely restricted to the lower Colorado River watershed and the Salton Sea, inhabiting freshwater and brackish water wetlands (Anderson and Ohmart 1985). Pairs may renest after failure of a previous nest. Clapper rails present in mangrove marshes along the west coast of Mexico may also be the specific Yuma clapper rail subspecies. Since this subspecies is so well camouflaged and usually found in dense vegetation, it is most easily recognized by its call, a series of dry kek kek kek notes, accelerating and then slowing. Within this mosaic of marsh conditions, Yuma clapper rail habitat will generally be provided by patches of bulrush and cattails interspersed with small patches of open water with water levels maintained at depths appropriate for this species (no more than12 inches). The Yuma Clapper Rail occurs primarily along the lower Colorado River and in the area of the Salton Sea in southeastern California. Displaying 12 data points . Eddleman, W. R. 1989, Biology of the Yuma clapper rail in the southwestern U.S. and northwestern Mexico, 4-AA-30-02060, U.S. Bureau Of Reclamation, Yuma Project Office, Yuma, AZ Google Scholar 6 Survey detections for the United States habitats have fluctuated between 467 and 809 individuals over the last 10 years. The Yuma clapper rail (Rallus longirostris yumanensis) also known as Yuma Ridgway's rail (R. obsoletus yumanensis), is a large, gray brown to dull cinnamon rail, with a slightly down curved bill and long legs and toes relative to the body. This conservation measure will include monitoring the effects of dredging and dredge spoil disposal associated with creating and maintaining backwaters and marshes. Avoidance of effects could be accomplished with the purchase, installation, and operation of two electric pumps sized to the current inflow at the Topock Marsh diversion inlet. The Yuma clapper rail was listed as endangered in 1976 under the Endangered Species Preservation Act, based on its precariously small population size in the U.S. and the threats to the new marsh habitat from channelization and dredging of the river in Arizona and California. … Implementation of this conservation measure would maintain existing habitat at Topock Marsh for the Yuma clapper rail, southwestern willow flycatcher, Colorado River cotton rat, western least bittern, California black rail, yellow-billed cuckoo, gilded flicker, vermilion flycatcher, Arizona Bell's vireo, and Sonoran yellow warbler. After breeding, adults go through a molt, lose their tail and flight feathers, and remain flightless for 3 to 4 weeks. If monitoring results indicate that management of the LCR MSCP conservation areas increases levels of selenium in created backwaters and marshes or in covered species that use them, the LCR MSCP will undertake research to develop feasible methods to manage the conservation areas in a manner that will eliminate or compensate for the effects of increased selenium levels. We, the U.S. Nests have been recorded in mid-March, but the average time frame is between April and May. If you require larger photos, please contact our webmaster Michelle Reilly at mreilly@usbr.gov. Conduct surveys and research, as appropriate, to collect information necessary to better define the species habitat requirements and to design and manage fully functioning created covered and evaluation species habitats. It is listed as threatened in Mexico. Impacts on groundwater levels that support covered species habitat at Topock Marsh will be avoided by maintaining water deliveries for maintenance of water levels and existing conditions. c. Rallus longirostris Yuma Clapper Rail Endangered . Yuma clapper rail habitat will be created and maintained as described in Section 5.4.3.3. in the HCP. Surveys for the Yuma clapper rail and the California black rail along the 38-mile unlined portion of the Coachella canal and adjacent wetlands, Imperial and Riverside counties, California. Additional threats include contaminants from agricultural tailwaters and exotic vegetation. Resource Information The item Yuma clapper rail : species range map represents a specific, individual, material embodiment of a distinct intellectual or artistic creation found in Indiana State Library. The ideal habitat has also been described as being a mosaic of emergent plant stands of different ages, interspersed with shallow pools of open water. LCR MSCP conducts a variety of research and monitoring activities along the LCR encompassing both MSCP and non-MSCP species. The first brood appears in March. Populations of these species have remained stable since 1999, with no significant trend, although with some fluctuations in some years. Threats include habitat destruction, primarily due to stream channelization and drying and flooding of marshes, resulting from water flow management on the lower Colorado River. The Yuma Ridgway’s rail (R. o. yumanensis) was first described in 1923 and was initially designated as a separate species, Rallus yumanensis. Facts Summary: The Clapper Rail (Rallus longirostris) is a species of concern belonging in the species group "birds" and found in the following area(s): Arizona, California.This species is also known by the following name(s): 3 subspecies endangered: Light-footed Clapper Rail (Rallus longirostris levipes), California Clapper Rail (Rallus longirostris obsoletus), Yuma Clapper Rail … In Arizona, habitat studies determined that sites with high coverage by surface water, low stem density, and moderate water depth were used for foraging during the nesting season, while sites with high stem density and shallower water near shorelines were used for nesting. This gallery includes photos of this species. In 1978, Arizona classified the Yuma clapper rail as a species of special concern, similar to the Federal status of endangered. Unlike the Clapper Rail, it also lives in freshwater marshes, along the lower … No Yuma clapper rail, American bittern, or black rail were detected during the 3-year period. status of the Yuma Clapper Rail at the Ciénega (Hinojosa-Huerta et al. Ongoing Current: FY … The endangered Yuma Clapper Rail can be spot nesting in the freshwater pond area encircled by the Michael Hardenberger Trail. At times, flow-related activities could lower river elevations to levels that could disrupt diversion of water from the river to the marsh. The Yuma clapper rail eats mostly crayfish, clams, isopods, freshwater shrimp, fish and various insects. Prolonged high water levels also can cause abandonment of territories. The incubation period ranges between 23-28 days. This subspecies prefers mature marsh stands along margins of shallow ponds with stable water levels. Low stem densities and little residual vegetation are features of year-round rail habitat. Significant populations are found in the Imperial Valley near and around the Salton Sea in California, and along the lower Gila River and the Gila River near the Phoenix Metropolitan area in central Arizona. There is no apparent association with brood mates or parents after fledging. These measures could include conducting surveys to determine if covered species are present and, if so, deferring the implementation of activities to avoid disturbance during the breeding season; redesigning the activities to avoid the need to disturb covered species habitat use areas; staging of equipment outside of covered species habitats; delineating the limits of vegetation control activities to ensure that only the vegetation that needs to be removed to maintain infrastructure is removed; stockpiling and disposing of removed vegetation in a manner that minimizes the risk of fire; and implementing BMPs to control erosion when implementing ground disturbing activities. Habitat used in early winter (November-December) has lower emergent stem density and ground coverage; less distance to water; greater overhead coverage by vegetation, distance to adjacent uplands, distance to vegetative edges, water depth and water coverage; and taller emergent plants than do randomly selected sites. This rail usually lays 7 to 11 eggs in a cup nest of grasses or sedges. First-hatched chicks are led from the nest by one parent, while the remaining parent continues incubation of remaining eggs. An analysis of survey data from 1995 to 2005 showed that between 35% and 55% of Yuma clapper rails detected in the United States were within the LCR MSCP boundaries. With the 1999 and 2000 survey data, we designed a long-term monitoring plan using the program MONITOR 6.2 (Gibbs 1995), with the objective of detecting population changes <3% per year, with a sig-nifi cance level of 95% and a statistical power of Larger patches would be expected to support multiple nesting pairs. Predation is the main mortality factor for adult Yuma clapper rails. This conservation measure applies to those species for which comparable measures are not subsumed under species-specific conservation measures (Section 5.7 in the HCP). Maintaining important existing habitat areas is necessary to ensure the continued existence of Yuma clapper rails in the LCR MSCP planning area, provide for the production of individuals that could disperse to and nest in LCR MSCP–created habitat, and support future recovery of the species. The lack of random flooding events that would shape and rejuvenate wetlands has allowed encroachment by woody vegetation and buildup of large amounts of decadent vegetation. Probably probes in mud or sand in or near shallow water or picks items off substrate. AMM1—To the extent practicable, avoid and minimize impacts of implementing the LCR MSCP on existing covered species habitats. Pairs are monogamous and both sexes assist in incubation and brood-rearing. B1 Continental – Species of Conservation Concern – Yuma Clapper Rail (43 breeding pair – 2009) D1 – Site Important to Special Status Avian Species – Federally listed Yuma Clapper Rail and SGCN Black Rail D3 – Rare, Unique, or Exceptional Representative Habitat/Ecological Community –Marsh and River Slough The yuma subspecies of Ridgway’s (formerly Clapper) Rail / Photo by US FWS The obsoletus subspecies of Ridgway’s Rail (formerly California Clapper Rail) / Photo by Bob Lewis All three subspecies are on the Federal endangered species list; two are also on the state endangered species list (SE) while the third is state threatened … They have been found to eat crayfish, weevils, water beetles, spiders, damselfly nymphs, dragonfly nymphs, shrimp, grasshoppers, insect eggs, ground beetles, plant seeds, fish (including mosquito fish, frogs (adults and tadpoles), leeches, crabs, an introduced freshwater clam, and a variety of plants. General Species Conservation Requirements, Species Specific Conservation Requirements, Implementation Report, FY 2021 Workplan and Budget, FY 2019 Accomplishment Report, CLRA1—Create 512 acres of Yuma clapper rail habitat, CLRA2—Maintain existing important Yuma clapper rail habitat areas. It is thought that this rail was not distributed along the Colorado River until suitable habitat was created through dam construction. CMM1—Reduce risk of loss of created habitat to wildfire. In Nevada, this subspecies can be found along the Virgin River and lower Muddy River, along the Colorado River around Lake Mohave, and in the Las Vegas Wash. In Arizona, males begin advertising in February and then form pairs. The marsh habitat at QWMA has in the past supported at least 4-6 pairs of the endangered Yuma Clapper Rail (Rallus longirostris yumanensis) and appropriate habitat exists for the endangered Southwestern Willow Flycatcher (Empidonax traillii extimus), although nesting has not been documented. This survey effort has occurred annually since 1978 and provides the data needed to assess the status of the endangered Yuma Clapper Rail. In addition to implementing AMM3 and AMM4 below, these measures could include conducting preconstruction surveys to determine if covered species are present and, if present, implementing habitat establishment and management activities during periods when the species would be least sensitive to those activities; or redesigning the activities to avoid the need to disturb sensitive habitat use areas; staging construction activities away from sensitive habitat use areas; and implementing BMPs to control erosion when implementing ground disturbing activities. Overall, clapper rails are selective, opportunistic, or limited in the variety of foods eaten depending upon habitat type. Ridgway's rail (Rallus obsoletus) is a near-threatened species of bird. Significant populations are also found in marshes at the south end of the Salton Sea. The applicants, under agreements with cooperating land management agencies, will provide funding to those agencies to maintain a portion of existing Yuma clapper rail habitat within the LCR MSCP planning area (Section 5.4.2 in the HCP). The Ridgway's rail (formerly the California clapper rail) and the mangrove rail have been recently split. Draft Revised Recovery Plan for the Yuma Clapper Rail: RD(1) 2: Arizona Ecological Services Field Office (602) 242-0210: Yuma Ridgways (clapper) rail: Rallus obsoletus [=longirostris] yumanensis: 3: 1.1.1: Assess rationale for setting recovery goal of 700-1,000 breeding birds in the 1983 recovery plan. 79, No. Most U.S. habitat is in national wildlife refuges and state wildlife management areas that are subject to water management practices of the U.S. Bureau of Reclamation. Some birds may winter in Mexico along the coasts of Sonora, Simaloa, and Nayarit. Surveys in the Colorado River Delta in Mexico determined that the majority of Yuma clapper rails are in the Ciénega de Santa Clara, the largest marsh wetland in the delta. Legal Status The western distinct population segment of the yellow-billed cuckoo was federally listed as threatened under the Endangered Species Act on 3 November 2014 (Federal Register /Vol. Administrative Report, U.S. Department of Interior, Bureau of Reclamation, Boulder City, NV, USA. A close relative of the Clapper Rail of the Atlantic and Gulf Coasts, and was considered part of the same species until recently. California originally listed the Yuma clapper rail as endangered in 1971; re-listed it as rare in … Young are able to fly after 10 weeks and become indistinguishable from adults. It is found principally in California's San Francisco Bay to southern Baja California.A member of the rail family, Rallidae, it is a chicken-sized bird that rarely flies. The Habitat Conservation Plan provides conservation measures specific to each species. obsoletus, R. o. levipes, R. o. beldingi, R. o. rhizophorae and R. o. nayaritensis. Management of LCR MSCP conservation areas will include contributing to and integrating with local, state, and Federal agency fire management plans. The Yuma clapper rail is also found east of the Colorado River along portions of the Gila, Salt, and Bill Williams river drainages and several other locations in central and southwestern Arizona. The species’ range now stretches north to the Virgin River and Beaver Dam Wash, near Littlefield, Arizona, and Mesquite, Nevada, the Muddy River near Overton, Nevada, and the Las Vegas Wash near Las Vegas, Nevada, and Ash Meadows NWR northwest of Las Vegas. Also, habitat was expanded through the creation of the Salton Sea in the early 1900s. Such measures could include alternative methods to achieve project goals, timing of activities, pre-activity surveys, and minimizing the area of effect, including offsite direct and indirect effects (e.g., avoiding or minimizing the need to place dredge spoil and discharge lines in covered species habitats; placing dredge spoils in a manner that will not affect covered species habitats). a. Strix occidentalis lucida Mexican Spotted Owl Threatened . Listed below are the species specific conservation measures for the Yuma clapper rail. CMM2—Replace created habitat affected by wildfire. Improvements to intake structures that allow water to continue to be diverted or other measures to maintain the water surface elevation will avoid effects on groundwater elevation. Rising water levels force rails to higher ground where they become predisposed to predation. Ridgway’s rails (Rallus obsoletus) are found in the United States and in Mexico. The bird probably winters in Mexico. The Yuma clapper rail is presumed to breed at 1 year of age. ... surveys to determine the breeding status of within the Wetlands ParkYuma clapper rail. AMM2—Avoid impacts of flow-related covered activities on covered species habitats at Topock Marsh, AMM3—To the extent practicable, avoid and minimize disturbance of covered bird species during the breeding season. Males are typically 20% larger than females. AMM5—Avoid impacts of operation, maintenance, and replacement of hydroelectric generation and transmission facilities on covered species in the LCR MSCP planning area. It has a patchy distribution in salt marshes of the Pacific Coast, as well as inland around the salty waters of the Salton Sea. Yuma clapper rails move into different cover types in winter, showing a preference for denser cover than in summer. Chicks are fed fragments of prey eaten by adults. To the extent practicable, before implementing activities associated with OM&R of hydroelectric generation and transmission facilities, measures will be identified and implemented that are necessary to avoid take of covered species where such activities could otherwise result in take. The Status of the Light-footed Clapper Rail Sanford R. Wilbur* The Light-footed Clapper Rail (Railus lon- girostris levipes) is one of three races of the Clap- per Rail considered by both the State of Califor- nia and the U.S. Department of Interior to be endangered (California Department of Fish and To the extent practicable, before initiating activities involved with river maintenance projects, measures will be identified and implemented that avoid or minimize take of covered species where such activities could otherwise result in take. A study will also be conducted to look at the effects of potential releases of selenium from dredging in general. The Yuma clapper rail was listed as endangered on March 11, 1967 pursuant to the Endangered Species Act of 1966. Yuma clapper rails are found in a variety of marsh types that are dominated by emergent plants, including southern cattail, bullwhip bulrush, three-square bulrush, and sedges. These small patches of habitat would provide cover for dispersing rails, thereby facilitating linkages between existing breeding populations and the colonization of created habitats. The Yuma clapper rail has been sighted along the Colorado River where Nevada, Arizona, and California meet, south to Yuma, Arizona, and into Mexico. The pond is a favorite nesting spot for the endangered Yuma clapper rail. Yuma clapper rail : species range map. Fish and Wildlife Service (Service), announce the availability of the Draft Yuma Clapper Rail (Rallus longirostris yumanensis) Recovery Plan, First Revision under the Endangered Species Act of 1973, as amended (Act). In the event of created-habitat degradation or loss as a result of wildfire, land management and habitat creation measures to support the reestablishment of native vegetation will be identified and implemented. The Yuma clapper rail is a marsh bird found in dense cattail or cattail-bulrush marshes along the lower Colorado River in Mexico north to the lower Muddy River and Virgin River in Utah above those rivers’ confluence with Lake Mead. Yuma clapper rails were declared Endangered in 1967, soon after the ESA was passed. 1988. This conservation measure applies to those species for which comparable measures are not subsumed under species-specific conservation measures (Section 5.7 in the HCP). The Yuma clapper rail is the largest rail found along the lower Colorado River. On September 14, 1972 an interagency meeting called by the Bureau of Reclamation was held in Parker, Arizona to discuss measures needed to ensure the survival of the Yuma clapper rail.Personnel from the California They are not applicable to species for which habitat would not be created under the LCR MSCP Conservation Plan, such as the desert tortoise, relict leopard frog, humpback chub, and threecorner milkvetch. Fish and Wildlife Service, Arizona Ecological Services Field Office, Attention 5-Year Review, 2321 West Royal Palm Road, Suite … Previously, the northern limit on the lower Colorado River was Laughlin Bay, Nevada. These include R.o. Created habitat will be monitored and adaptively managed over time to determine the types and frequency of management activities that may be required to maintain created cottonwood-willow, honey mesquite, marsh, and backwater land cover as habitat for covered species. Furthermore, some taxonomists consider that the King rail and Aztec rail should … Significant populations of Yuma clapper rail are found within the LCR MSCP boundaries in reaches 3 through 6. Although mortality or reproductive impairment have not been documented in Yuma clapper rail populations along the lower Colorado River, concentrations of selenium in the Yuma clapper rails food chain may be within the range that could cause adverse effects on reproduction. Coyotes, raccoons, and raptors such as northern harrier, great horned owl, and Harris’ hawk, have been documented as predators of the Yuma clapper rail. Young rails learn foraging strategies from adults but may be fed, in part, by adults until the age of 6 weeks. Young can fly in about 9 to 10 weeks. yumanensis) Export CSV file. Observers detected least bittern, sora and Virginia rail each year, as well as the non-target species pied-billed grebe, common moorhen and American coot.

Yuma Clapper Rail[English] Source: Zoonomen - Zoological Nomenclature Resource, 2006.07.04, website … Yuma clapper rails move into different cover types in winter, showing a preference for denser cover than in summer. Nest sites selected by this subspecies are near upland areas in shallow sites dominated by mature vegetation, often in the base of a shrub. Conduct monitoring of selenium levels in sediment, water, and/or biota present in LCR MSCP created backwater and marsh land cover types. The Yuma clapper rail was listed as endangered on March 11, 1967 pursuant to the Endangered Species Act of 1966. On the lower Colorado River, this species is currently found in scattered marshes from the Colorado River Delta in Mexico, to Topock Marsh at Havasu National Wildlife Refuge (NWR), near Needles, California. In 2006, the survey became a multi-species survey effort due to an increase in training provided to the agency personnel conducting the surveys. Marshes created to provide Yuma clapper rail habitat will be designed and managed to provide an integrated mosaic of wetland vegetation types, water depths, and open water areas.

Conservation areas will be designed to contain wildfire and facilitate rapid response to suppress fires (e.g., fire management plans will be an element of each conservation area management plan). California originally listed the Yuma clapper rail as endangered in 1971; re-listed it as rare in 1978, and currently lists it as threatened. Yuma Clapper Rail (Rallus longirostris ssp. b. Empidonax traillii extimus Southwestern Willow Flycatcher Endangered . Yuma clapper rail nests can be found near shore, in shallow water, and in marsh interiors. Clapper rails are sight feeders, gleaning the surface, making shallow and sometimes deep probes, gleaning below the water surface, moving at times erratically in search of prey, and at other times moving slowly and deliberately. Marsh Bird Monitoring, 2011 3 A large-footed marsh bird distinguished from other clapper rails by its paler, duller underparts and grayish edging of dorsal feathers; cheeks and postoculars bluish or ashy gray. Striped skunks are a potential predator of adult rails, and bullfrogs, black bass, soft shell turtle, and common king snakes are potential predators of young rails and eggs. Table 5-9 in the HCP describes the breeding period for each of the covered species during which, to the extent practicable, vegetation management activities in each species' habitat will be avoided. Fire during the breeding season (mid-March to early September) can cause loss of eggs, young, and some adults. While the status of the Yuma clapper rail has … Though weighing a mere 10 ounces, the clapper rail can grow up to 14.5 inches long and sport a 19-inch … Habitat maintenance would likely be undertaken in conjunction with the maintenance of existing California black rail habitat. The Yuma clapper rail was found along the lower Colorado River after construction of dams and the subsequent creation of marsh habitat. If monitoring results indicate that current or future dredging and dredge spoil disposal methods increase selenium levels, the LCR MSCP will only implement methods that will have the least effect on selenium levels. of its habitat and because of this and other reasons the Yuma clapper rail was thought to be faced with extinction. It is one of the smaller subspecies of clapper rails. Most of the U.S. breeding population is resident. Status: Subspecies California Clapper Rail, Light-footed Clapper Rail, and Yuma Clapper Rail are endangered. 192 / Friday, October 3, 2014 /Rules and Regulations). Clapper rail young are precocial, meaning they are active and able to move freely after hatching and require little parental care. LCR MSCP conservation measures that could result in such temporary disturbances will, to the extent practicable, be designed and implemented to avoid or minimize the potential for disturbance. The clapper rail (Rallus crepitans) is a member of the rail family, Rallidae.The taxonomy for this species is confusing and still being determined. Maintaining water deliveries to Topock Marsh will also maintain razorback sucker and bonytail habitat associated with disconnected backwaters managed for these species. The pumps would most likely need to be operated during summer to make up for the lower flow periods. Populations also occur There are up to six subspecies of Ridgway’s rail. Degradation of habitat is thought to be a factor contributing to declines in rail populations. Nevada classifies the Yuma clapper rail as endangered. This item is available to borrow from 1 library branch. Create and manage 512 acres of marsh to provide Yuma clapper rail habitat (Figure 5-2 in the HCP).
