Western Snowy Plover Recovery Plan PRIMARY AUTHORS This final recovery plan was prepared by Kelly Hornaday, Ina Pisani, and Betty Warne of our Sacramento Fish and Wildlife Office. Ruth Pratt of the Sacramento Fish and Wildlife Office coordinated preparation of the draft recovery plan and acted as Recovery Team Manager. We gratefully acknowledge the efforts of the Pacific Coast Western Snowy Plover Recovery Team in preparing this recovery plan. Special acknowledgment is also given to Nadav Nur, Point Reyes Bird Observatory, Stinson Beach, California, for his work on the population viability analysis. ii DISCLAIMER Recovery plans delineate reasonable actions that are believed to be required to recover and/or protect listed species. We, the U.S. Fish and Wildlife Service, publish recovery plans, sometimes preparing them with the assistance of recovery teams, contractors, State agencies, and others. Recovery teams serve as independent advisors to the U.S. Fish and Wildlife Service. Objectives of the recovery plan will be attained and 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 actions, and may not represent the views or the official positions or approval of any individuals or agencies involved in the recovery plan formulation other than our own. They represent our official position only after they have been signed by the Director, Regional Director, or Operations Manager as approved. Approved recovery plans are subject to modification as dictated by new findings, changes in species status, and the completion of recovery actions.

Oregon Natural Heritage Program Yuba City, California Portland, Oregon v EXECUTIVE SUMMARY CURRENT SPECIES STATUS: The Pacific coast population of the western snowy plover (Charadrius alexandrinus nivosus) (western snowy plover) is federally listed as threatened. The current Pacific coast breeding population extends from Damon Point, Washington, south to Bahia Magdalena, Baja California, Mexico (including both Pacific and Gulf of California coasts). The western snowy plover winters mainly in coastal areas from southern Washington to Central America. HABITAT REQUIREMENTS AND LIMITING FACTORS: The Pacific coast population of the western snowy plover breeds primarily above the high tide line on coastal beaches, sand spits, dune-backed beaches, sparsely-vegetated dunes, beaches at creek and river mouths, and salt pans at lagoons and estuaries. Less common nesting habitats include bluff-backed beaches, dredged material disposal sites, salt pond levees, dry salt ponds, and river bars. In winter, western snowy plovers are found on many of the beaches used for nesting as well as on beaches where they do not nest, in man-made salt ponds, and on estuarine sand and mud flats. Habitat degradation caused by human disturbance, urban development, introduced beachgrass (Ammophila spp.), and expanding predator populations have resulted in a decline in active nesting areas and in the size of the breeding and wintering populations. RECOVERY OBJECTIVE: The primary objective of this recovery plan is to remove the Pacific coast population of the western snowy plover from the List of Endangered and Threatened Wildlife and Plants by: (1) increasing population numbers distributed across the range of the Pacific coast population of the western snowy plover; (2) conducting intensive ongoing management for the species and its habitat and developing mechanisms to ensure management in perpetuity; and (3) monitoring western snowy plover populations and threats to determine success of recovery actions and refine management actions. vi RECOVERY PRIORITY: 3C, per criteria published by Federal Register Notice (U.S. Fish and Wildlife Service 1983). RECOVERY CRITERIA: The Pacific coast population of the western snowy plover will be considered for delisting when the following criteria have been met: 1. An average of 3,000 breeding adults has been maintained for 10 years, distributed among 6 recovery units as follows: Washington and Oregon, 250 breeding adults; Del Norte to Mendocino Counties, California, 150 breeding adults; San Francisco Bay, California, 500 breeding adults; Sonoma to Monterey Counties, California, 400 breeding adults; San Luis Obispo to Ventura Counties, California, 1,200 breeding adults; and Los Angeles to San Diego Counties, California, 500 breeding adults. This criterion also includes implementing monitoring of site-specific threats, incorporation of management activities into management plans to ameliorate or eliminate those threats, completion of research necessary to modify management and monitoring actions, and development of a post-delisting monitoring plan. 2. A yearly average productivity of at least one (1.0) fledged chick per male has been maintained in each recovery unit in the last 5 years prior to delisting. 3. Mechanisms have been developed and implemented to assure long-term protection and management of breeding, wintering, and migration areas to maintain the subpopulation sizes and average productivity specified in Criteria 1 and 2. These mechanisms include establishment of recovery unit working groups, development and implementation of participation plans, development and implementation of management plans for Federal and State lands, protection and management of private lands, and public outreach and education. ACTIONS NEEDED: 1. Monitor breeding and wintering populations and habitats of the Pacific coast population of the western snowy plover to determine progress of recovery actions to maximize survival and productivity. vii 2. Manage breeding and wintering habitat of the Pacific coast population of the western snowy plover to ameliorate or eliminate threats and maximize survival and productivity. 3. Develop mechanisms for long-term management and protection of western snowy plovers and their breeding and wintering habitat. 4. Conduct scientific investigations that facilitate the recovery of the western snowy plover. 5. Conduct public information and education programs

  • Periodic Status Review for the Snowy Plover in Washington
    STATE OF WASHINGTON February 2016 Periodic Status Review for the Snowy Plover Derek W. Stinson Washington Department of FISH AND WILDLIFE Wildlife Program The Washington Department of Fish and Wildlife maintains a list of endangered, threatened, and sensitive species (Washington Administrative Codes 232-12-014 and 232-12-011). In 1990, the Washington Wildlife Commission adopted listing procedures developed by a group of citizens, interest groups, and state and federal agencies (Washington Administrative Code 232-12-297). The procedures include how species list- ings will be initiated, criteria for listing and delisting, a requirement for public review, the development of recovery or management plans, and the periodic review of listed species. The Washington Department of Fish and Wildlife is directed to conduct reviews of each endangered, threat- ened, or sensitive wildlife species at least every five years after the date of its listing by the Washington Fish and Wildlife Commission. The periodic status reviews are designed to include an update of the species status report to determine whether the status of the species warrants its current listing status or deserves reclas- sification. The agency notifies the general public and specific parties who have expressed their interest to the Department of the periodic status review at least one year prior to the five-year period so that they may submit new scientific data to be included in the review. The agency notifies the public of its recommenda- tion at least 30 days prior to presenting the findings to the Fish and Wildlife Commission. In addition, if the agency determines that new information suggests that the classification of a species should be changed from its present state, the agency prepares documents to determine the environmental consequences of adopting the recommendations pursuant to requirements of the State Environmental Policy Act.

  • Habitat Selection and Response to Restoration by Breeding
    HABITAT SELECTION AND RESPONSE TO RESTORATION BY BREEDING WESTERN SNOWY PLOVERS IN COASTAL NORTHERN CALIFORNIA By Stephanie D. Leja A Thesis Presented to The Faculty of Humboldt State University In Partial Fulfillment of the Requirements for the Degree Master of Science in Natural Resources: Wildlife Committee Membership Dr. Mark A. Colwell, Committee Chair Dr. Matthew D. Johnson, Committee Member Dr. William T. Bean, Committee Member Dr. Alison O'Dowd, Graduate Coordinator December 2015 ABSTRACT HABITAT SELECTION AND RESPONSE TO RESTORATION BY BREEDING WESTERN SNOWY PLOVERS IN COASTAL NORTHERN CALIFORNIA Stephanie D. Leja Habitat loss and degradation by invasive species is a primary limitation to the recovery of the Western Snowy Plover (Charadrius nivosus nivosus), a federally threatened shorebird that resides on coastal beaches in Humboldt County, California. This habitat threat posed by European Beachgrass (Ammophila arenaria) is often mitigated through dune restoration. Some habitat features altered by restoration (e.g., beach width) may influence plover breeding habitat selection. Further study was needed to determine which physical and social features (e.g., presence of conspecifics) influence plover nesting locations. I evaluated this response of plovers to restoration and identified characteristics that influence nest site selection. In an Information-Theoretic framework, I compared nests (n = 81) and random locations within habitat using logistic regression and Generalized Linear Mixed Models to produce Resource Selection Function analyses and conduct model selection analyses. Plovers nested on wider, less sloped beaches, with greater coverage of natural debris (e.g., driftwood, shells) and more conspecifics than at random locations. Plovers nested primarily (84%) in restored habitats, although this was influenced by one human-restored site with 33% of nests.

Colwell Wildlife Department, Humboldt State University, 1 Harpst Street, Arcata, CA 95521, USA *Corresponding author: [email protected] Raby, K.M. & M.A. Colwell. 2020. Habitat restoration improves Western Snowy Plover nest survival. Wader Study 127(2): 130–140. Productivity measures, such as nest survival rates, are often used to indirectly Keywords assess habitat quality and guide management practices for conservation of Charadrius nivosus threatened and endangered species. The Western Snowy Plover Charadrius nivosus nivosus is listed as threatened due to three limiting factors: human disturbance, habitat quality increasing native and introduced predator populations, and the loss and degra- productivity dation of habitat. We examined the relative influence of these three limiting factors on nest survival, using 14 years of data (n = 610 nests) at eight sites in conservation Humboldt County, California, USA. Survival varied by year and site, and increased predation with nest age and as the breeding season progressed. Habitat restoration had human disturbance the greatest influence on nest survival. Both natural (tidal overwash) and human- implemented restoration had a positive effect on nest survival, whereas unre- shorebirds stored areas had a negative effect. Naturally restored areas had a stronger effect waders (higher and less variable survival estimates) on nest survival than human-restored threatened areas. Human and predator activity were not strong predictors of nest survival. Consequently, we recommend that managers focus on conserving, maintaining, and creating restoration areas to enhance Snowy Plover nest survival.

Harsh, but dynamic processes create unique habitats among the dunes for imperiled plants and animals such as La Graciosa thistle, marsh sandwort, California red- legged frog, and western snowy plover. The Refuge lies within the Guadalupe-Nipomo Dunes Complex (Dunes Complex), an 18-mile- long stretch of coastal dunes located north of Point Sal and south of Pismo Beach. To conserve the dynamic landscape and imperiled natural resources of the Refuge and the Dunes Complex, the Service works cooperatively with other agencies, non-profit organizations, local businesses, private landowners, and private citizens. Working together, we instill stewardship through activities that include habitat restoration, protection of cultural resources, recovery of threatened and endangered species, and opportunities for high-quality visitor experiences in this unique and spectacular dunes landscape. Such cooperative efforts enable all partners to share limited resources to meet common goals, thereby achieving much more together than we could alone.

In particular, estimates of survivorship and reproductive success derived from annual records of uniquely marked birds inform management practices that attempt to increase population size, which is especially important for threatened and endangered taxa (e.g., Pakanen 2016). Recently, we summarized population growth (Colwell et al . 2017), lifetime reproductive success (Herman & Colwell 2015), and annual variation in sur - vivorship (Mullin et al . 2010, Colwell et al . 2013) for the Snowy Plover Charadrius nivosus . Here, we submit obser - vations of a male Snowy Plover (Fig. 1) who, at 16 years of age, continues to offer insight into the conservation challenges faced by the species. Longevity – On 26 June 2001, we banded a newly hatched Snowy Plover at Eel River Wildlife Area in Humboldt County, California, USA (Fig. 2).

The Pacific coast population of the Snowy Plover Charadrius nivosus nivosus is Keywords listed as threatened under the U.S. Endangered Species Act, which requires Snowy Plover demographic data to inform management directed at increasing the population. Accordingly, we summarized a 16-year dataset on population size and growth, Charadrius nivosus return rates, and productivity of a color-marked breeding population in coastal population growth northern California, one of six recovery units for the listed population. The geo - graphically isolated population varied annually in size (19–74 breeding adults), threatened with an early nine-year decline ( λ = 0.92 ± 0.30 ) followed by a seven-year increase vital rates (λ = 1.22 ± 0.19 ). Overall, productivity averaged 0.85 ± 0.29 chicks fledged per male, which is well below that identified by viability analyses to maintain the population.
