They have an overall body length of 17 cm (01) and weigh between 46 and 64 grams (average 55 gm.) (02,03). Wing lengths span 11.0-12.7 cm, tarsi range from 2.1-2.4 cm, and culmen lengths vary from 1.0 to 1.4 cm (02,03,04). Throughout the year, adults have sand-colored upper body parts, white undersides, and orange legs. During the breeding season, adults acquire single black forehead and breast bands, and orange bills (04,05,06,07). In general, males have brighter bands than females, and inland birds have more complete bands than East Coast birds (02,04,08,09). Post-breeding birds lose the bands and orange on their bill but are easily distinguished from snowy plovers (Charadrius alexandrinus) and collared plovers (Charadrius collaris) by their slightly larger size and orange legs (10). Fledgling plumage is similar to adult post-breeding plumage. Juveniles acquire adult plumage the spring Taxonomy - 1 (DRAFT) - Taxonomy Species PLOVER, PIPING Species Id ESIS103002 Date 14 MAR 96 after they hatch (04,11). Taxonomy: Described as a race of Charadrius hiaticula (12), the taxonomy of piping plovers has undergone a number of revisions (12,13, 14). Ord (1824) was the first to consider piping plovers a separate species, but it was not until the fourth edition of the AOU Checklist that the binomial, Aegialitis meloda, was changed to Charadrius melodus (02,08,15,16). In addition to changes in the binomial, ornithologists have argued for over 100 years about acceptance of 2 subspecies: C. m. melodus (Atlantic birds) and C. m. circumcinctus (inland birds). The first 2 editions of the AOU Checklist listed the 2 forms, the third and fourth listed 1 form (14,17,18,19). Moser's argument that breast bands differed between inland and coastal birds facilitated changing back to 2 forms in the 1945 supplement of the checklist (13). In 1959, Wilcox reported a variety of breast band forms from birds on Long Island (02). Subsequent morphological measurements of Atlantic and inland birds did not indicate there was a significant difference between birds from different regions (02,08, 20). Haig (11) collected electrophoretic samples from piping plovers in Saskatchewan, Manitoba, North Dakota, Minnesota, and New Brunswick, and was not able to detect a genetic difference between local or regional populations. The subspecies designation is accepted by the AOU 1957 Checklist only (21). Reference Materials: Early specimens are referenced in Wilson and Bonaparte (12). Haig (25) has a computerized listing of most piping plover skins in North America. Accurate drawings of adults and chicks appear in Johnsgard (06). Jehl (22) has good comparative pictures of piping plover and other Charadrinae chicks. The "Prairie Waters" segment of the Canadian Broadcasting Corp. show "The Nature of Things" has 20 minutes of piping plover behavior (23). Likewise, the Non-Game program of the Minnesota Dept. of Natural Resources has an 18 minute audio slide show which features piping plover adults, chicks, nests, eggs, habitat, etc. (24). Finally, the Cornell Univ., Laboratory of Ornithology has piping plover slides in their collection (25). Taxonomy - 2

INTERNATIONAL STATUSES, TREATIES, AND AGREEMENTS: The Committee on the Status of Endangered Wildlife in Canada (COSEWIC) lists the piping plover as Endangered. Ontario also lists the piping plover as Endangered on their Provincial list (Endangered Species Act, Chapter 138, Revised Stat. of Ontario, 1980). ECONOMIC STATUSES: The piping plover is a rare and attractive shorebird, unknown to most beachgoers. The species has a nonconsumptive recreational value to bird watchers and in some areas of the species range it has been known to have a value for food. There is no negative value to man. The species was hunted for recreation/food in the early 20th Century and this may still be a problem in Newfoundland and the West Indies (05,34,40). Status - 6

Areas surrounding rivers are pasture, cropland, floodplain forest, herbaceous rangeland on tall grass prairie and sagebrush areas. Nesting areas are characterized by dry, barren to sparsely vegetated sandbars located midstream in wide, open channel beds. Vegetative cover within nesting areas is less than 20%. Spoil islands are created by sand and gravel mining operations located adjacent to the river and by within-stream dredging for pipeline crossings and water intakes. Threats to these areas stem primarily from water control projects developed for power companies, irrigation, navigation, recreation and ranching or farming interests. Raising water levels, via formation of reservoirs, floods nesting areas. Permanently lowering water levels (via water withdrawl projects) promotes vegetation encroachment on nest sites (28,30,35,36,38,47,48). Reservoir construction is the single most cause of habitat loss on prairie rivers. Reservoirs inundated nesting areas upstream and reduced the natural scouring actions of floods downstream. Sporadic releases from reservoir dams for power production and water demands downstream often inundate nesting areas during the nesting period (70). Other significant losses occur from recreation activities within nesting areas (70). Prairie sloughs and saline wetlands: Small, permanent to seasonally flooded, palustrine wetlands are used by breeding birds in Montana, North Dakota, South Dakota, Nebraska, and possibly Iowa (28, 30,37,47,49,50). Typically, piping plovers place nests on dry, salt flats or gravel beaches along the edges of these wetlands (37,51,52, 53). Grassland areas adjacent to nest sites are pasture or rangeland composed of tall-grass prairie, short-grass prairie, or sagebrush. Occasionally, birds utilize spoil piles, settling ponds, reclaimed mining areas, or gravel pits (27,37,45,50,54,55). Drainage or deepening (for freshening purposes) of prairie wetlands pose a major threat to nesting habitat (09,27,28,37). Livestock pose a major threat to plover nesting by trampling wetland shorelines and nests. Large inland lakes: Current utilization of large U.S. inland lakes is restricted to Lake of the Woods, MN (56,57), Lake Michigan (41,58), and Lake Superior (41,59). In these lacustrine areas, piping plovers nest on open, sand and gravel beaches on islands or the mainland. Beaches may be adjacent to dunes, and are surrounded by prairie parkland (Lake of the Woods) or northern hardwood forest (Great Lakes). Recreational development threatens many of the nesting areas, as does water level manipulation. Industrial sites in Duluth, MN harbor provide habitat in the form of spoil islands, yet, industrial use of the area (i.e., human presence) poses a threat to nesting birds (59,60). Atlantic ocean beach areas: During the breeding season, piping plovers place nests on sandy, gravel and/or cobbled marine beaches along the Atlantic coast from Newfoundland to South Carolina (26,28, 30,31,47). Breeding pairs have been reported from South Carolina; however, no nests have been found there yet (68). Off-shore islands, with appropriate habitat, are also used. Birds place nests at the base of dunes or close to the vegetation edge (02,26,33,61,62). Breeding birds generally feed on territories, but inter-tidal estuarine beach bars and flats may be used if adjacent to territories. Post-breeding birds use similar habitat along the south Atlantic coast of the U.S. (47). Residential, commercial, industrial, and recreational interests threaten many of these areas. Gulf of Mexico winter sites: During the winter, piping plovers utilize beaches, sandflats, and dunes along the Gulf of Mexico coastal beaches and adjacent off-shore islands. Spoil islands in the Habitat Associations - 3 Intracoastal Waterway are also used. Stabilization of back sides of barrier islands (e.g., Padre Island, TX) destroys ephemeral, but essential, sandflat habitat. Recreational and industrial development (including gas and oil interests) of beaches causes further decline in habitat availability and quality (10,63). Nest sites: Specific parameters for nest sites are described in the section "N-Biology" field. Much of what appears to be suitable piping plover habitat is not used by the birds. Other factors (e.g., social, food supply, or genetic factors), not directly related to habitat selection, may be involved. Impact of habitat deterioration: Threats to piping plover habitat are outlined in the "N-Reason" field. Currently, numbers of piping plovers are low enough so that destruction of any part of their habitat significantly impacts the species. It is critical to keep in mind that the status of winter and migratory habitats are not well understood. Habitat Associations - 4

LIFE HISTORY

FOOD HABITS: Diet: Very little is known about the diet of piping plovers or their foraging behavior during any phase of the annual cycle. The species' sensitivity to human disturbance makes it difficult and unwise to sample food on territories while birds are present. Low population numbers rule out collection of birds for stomach content analysis. Cairns (33) was unsuccessful in her attempt to develop an emetic that would force chicks to regurgitate their food. Bent (05) reported the stomach contents of 4 piping plovers from Alabama to contain marine worms, insects (fly larvae and beetles), crustaceans, molluscs, and other small marine animals (and their eggs). Similarly, in Nova Scotia, Cairns (33) observed piping plovers feeding on marine worms averaging 2.5-7.5 cm in length. She suggested their diet consisted of marine worms, minute worms, and crustaceans. Whyte (51) carried out invertebrate sampling on piping plover territories at Big Quill Lake in Saskatchewan, and found the following families present: Coleoptera: Carabidae (26.9%), Dytiscidae (15.3%); Hemiptera: Corixidae (19.2%) and Saldidae (2.3%); and Diptera: Chironomidae (9.5%) and Ephidridae (2.6%). Dytiscid adults and larvae, corixids, and chironomid larvae were collected in water seeps 1 m from the water's edge. He found ephidrids to be more common further upland, and collected carabids and dytiscids from the shoreline to the edge of the grassland cover (Haig has numerous observations of piping plovers eating grasshoppers and spiders in the grass near nest sites in Manitoba (03)). His sampling was carried out in August which may have affected the results, but it is the only sampling of its kind (as of 1986). Captive birds have done well on a diet of commercial feed, chopped egg yolks, and mealworms (64). Foraging behavior: Piping plovers have been observed using two methods of foraging: 1) foot-trembling, whereby one foot is extended and shaken on the substrate surface and, 2) run and peck, which involves the bird taking a few short steps, stopping, and then pecking at a prey item (03,05,33,51). Cairns (33) reported that young chicks did not forage via foot-trembling, however, Haig (03) has frequently observed this behavior in chicks less than 5 days old. A difference between alkali mudflat and coastal beach foraging substrate may account for this variation in observations. Nichols (65) briefly described piping plovers foraging by treading in the water to stir up invertebrates, but it has not been reported since. Feeding territories: Whyte (51) classified feeding areas on Big Quill Lake, as being either a major area consisting of the area from the shoreline up to 15 m upland, or a minor area which is the area surrounding the nest. He found that while the percentage of feeding near the shore varies by sex, age, and stage of breeding season, the vast majority of feeding takes place within 5 m of the water's edge. Significant deviation from the trend only occurred at sunset when parents and broods returned to higher ground (51). Establishment of feeding terrirories varies with habitat and stage of the annual cycle. Birds that have just arrived on the breeding grounds, and post-breeding birds tend to forage on undefended areas (03,33). During courtship, incubation, and early brood-rearing Life History - 1 (DRAFT) - Life History Species PLOVER, PIPING Species Id ESIS103002 Date 14 MAR 96 most piping plovers forage on territories (03,33,51). Haig (10) observed piping plovers feeding on territories on some Texas beaches in January 1984, but did not observe establishment of territories on sandflat feeding areas. Winter studies underway in Alabama may clarify foraging habits for all of the southeast U.S. wintering range (66). HOME RANGE/TERRITORY: Piping plovers establish territories during the breeding season (i.e., throughout courtship, laying, incubation, and brood care) and possibly during winter (02,03,10,33,51). During the breeding season, both members of the pair defend a nesting territory that may or may not contain a feeding territory (03). Piping plovers in Nova Scotia had separate nesting and feeding territories (33), while birds in Saskatchewan had contiguous territories (51). Piping plovers in Manitoba exhibited both patterns depending on study area (03). Spacing of territories varies from 1 pair per beach to a semi-colonial situation where 30 or more pairs place nests less than 25 m apart (02,03,33,36,37,51,52,56,59). Home range during the breeding season is usually limited to the wetland, lakeshore, or section of beach that an individuals' nest is placed on. In Manitoba, however, birds whose nests were destroyed, often established territories in a diffrent area prior to renesting. Males that established new territories generally changed areas while females generally established new territories in the same general area. Distances between study sites varied from 3-100 km (11). Results of an investigation into movements of individual birds between Dauphin Island, Alabama beaches and spoil islands will provide better information about home ranges of non-breeding birds (66). Refer to food habits above for a discussion of feeding territories of post-breeding birds (66). PERIODICITY: Piping plovers are migratory shorebirds that spend approximately 3-4 months on northern U.S. and southern Canadian breeding sites. The remainder of the year they inhabit Gulf of Mexico, Caribbean, and southern U.S. beaches and sandflats (28,30). Daily activities during the non-breeding period have not been described. During the breeding season, adults in Manitoba were active from at least an hour prior to sunrise to at least an hour after sunset. Peak daily activity (including: feeding, territory defense, and courtship) in Manitoba occurred within an hour of sunrise and sunset (03). In Nova Scotia, feeding activity was highest at low or falling tides (33). Courting males will perform aerial displays as late as 3 a.m. During incubation, males and females alternate incubation bouts that vary from 15 minutes - 2 hours. It is not known if one adult remains on the nest throughout the night (03). MIGRATION PATTERNS: Piping plovers are a migratory species, yet less is known about their migratory activities than most of their other life history traits. Band returns indicate birds breeding along the Atlantic coast move to more southerly Atlantic winter sites (30). Great Lakes and Life History - 2 (DRAFT) - Life History Species PLOVER, PIPING Species Id ESIS103002 Date 14 MAR 96 northern Great Plains birds winter along the Gulf of Mexico, yet their fall and spring migratory pathways are unknown (09,30). Areas that have been used by migratory piping plovers are briefly discussed in the "N-Occurrence" field, but none of the areas have been shown to be major "stop-over" sites (47). Piping plovers may complete their migration without significant stopping. More research is needed on this topic. COVER/SHELTER REQUIREMENTS: Prairie Rivers: Piping plovers nesting on the Missouri, Platte, and Niobrara Rivers utilize sand and gravel bars, beaches, sandflats, dredge spoil and natural islands, and drained river floodplains in palustrine, littoral, lacustrine, and lower perennial riverine habitats. Areas surrounding rivers are pasture, cropland, floodplain forest, herbaceous rangeland on tall grass prairie and sagebrush areas. Nesting areas are characterized by dry, barren to sparsely vegetated sandbars located midstream in wide, open channel beds. Vegetative cover within nesting areas is less than 20%. Spoil islands are created by sand and gravel mining operations located adjacent to the river and by within-stream dredging for pipeline crossings and water intakes. Threats to these areas stem primarily from water control projects developed for power companies, irrigation, navigation, recreation and ranching or farming interests. Raising water levels, via formation of reservoirs, floods nesting areas. Permanently lowering water levels (via water withdrawl projects) promotes vegetation encroachment on nest sites (28,30,35,36,38,47,48). Reservoir construction is the single most cause of habitat loss on prairie rivers. Reservoirs inundated nesting areas upstream and reduced the natural scouring actions of floods downstream. Sporadic releases from reservoir dams for power production and water demands downstream often inundate nesting areas during the nesting period (70). Other significant losses occur from recreation activities within nesting areas (70). Prairie sloughs and saline wetlands: Small, permanent to seasonally flooded, palustrine wetlands are used by breeding birds in Montana, North Dakota, South Dakota, Nebraska, and possibly Iowa (28, 30,37,47,49,50). Typically, piping plovers place nests on dry, salt flats or gravel beaches along the edges of these wetlands (37,51,52, 53). Grassland areas adjacent to nest sites are pasture or rangeland composed of tall-grass prairie, short-grass prairie, or sagebrush. Occasionally, birds utilize spoil piles, settling ponds, reclaimed mining areas, or gravel pits instead of natural habitat (27,37,45,50, 54,55). Drainage or deepening (for freshening purposes) of prairie wetlands pose a major threat to nesting habitat (09,27,28,37). Large inland lakes: Current utilization of large U.S. inland lakes is restricted to Lake of the Woods, MN (56,57), Lake Michigan (41,58), Lake Superior (41,59), and possibly Lake Ontario. In these lacustrine areas, piping plovers nest on open, sand and gravel beaches on islands or the mainland. Beaches may be adjacent to dunes, and are surrounded by prairie parkland (Lake of the Woods) or northern hardwood forest (Great Lakes). Recreational development threatens many of the nesting areas, as does water level manipulation. Industrial sites in Duluth, MN harbor provide habitat in the form of Life History - 3 (DRAFT) - Life History Species PLOVER, PIPING Species Id ESIS103002 Date 14 MAR 96 spoil islands, yet, industrial use of the area poses a threat to nesting birds (59,60). Atlantic ocean beach areas: During the breeding season, piping plovers place nests on sandy, gravel and/or cobbled marine beaches along the Atlantic coast from Maine to North Carolina (26,28,30,31, 47). Breeding pairs have been reported from South Carolina; however, no nests have been found yet (68). Off-shore islands, with appropriate habitat, are also used. Birds place nests at the base of dunes or close to the vegetation edge (02,26,33,61,62). Breeding birds generally feed on territories, but intertidal estuarine beach bars and flats may be used if adjacent to territories. Non-breeding birds use similar habitat along the south Atlantic coast of the U.S. (47). Residential, commercial, industrial, and recreational interests threaten many of these areas. Gulf of Mexico winter sites: During the winter, piping plovers utilize beaches, sandflats, and dunes along the Gulf of Mexico coastal beaches and adjacent off-shore islands. Spoil islands in the Intercoastal Waterway are also used. Stabilization of back sides of barrier islands (e.g., Padre Island, TX) destroys ephemeral, but essential, sandflat habitat. Recreational and industrial development (including gas and oil interests) of beaches causes further decline in habitat availability and quality (10,63). Nest sites: Specific parameters for nest sites are described below. REPRODUCTIVE SITE REQUIREMENTS: Piping plovers perform most courtship displays, including nest-building, on their nesting territories. Males usually initiate nest scrape digging on an unvegetated sand or gravel substrate high on the beach line (03,33). Both males and females perform a ritualized stone-tossing behavior whereby nest-scrapes are lined with small pebbles or shell fragments (03,33). Finished nest cups are approximately 2 cm deep and 6 cm in diameter (03). Since piping plover habitat is so variable across North America, it is difficult to characterize specific dimensions for the "ideal" nest site. Prindiville's (37) general conclusions from North Dakota are indicative of patterns reported in other studies. She found beaches used for nest sites were significantly wider than those not selected. Nesting territories had more gravel, and it was more evenly distributed, than on unused beaches. Vegetation was scarce and more clumped on nesting territories. Finally, territories with gravel substrate were more successful than territories with alkali substrate (37). Nest-site parameters for specific areas are discussed in numerous papers: (33,36,37,41,51,52,59,61,67). REPRODUCTIVE CHARACTERISTICS: Piping plovers exhibit a monogamous mating system, although one instance of polyandry was observed in Manitoba (27,56). While an individual only forms one pair bond at a time (extra-bond copulations were rarely observed in Manitoba), mate-switching between nest attempts and years occurs frequently (02,11,56). Mate-switching between years occurs regardless of previous reproductive success (11, 56). In Manitoba, most former mates were present in nesting areas in Life History - 4 (DRAFT) - Life History Species PLOVER, PIPING Species Id ESIS103002 Date 14 MAR 96 subsequent years, thus making it possible for pair-bonds to persist (11). Males and females are able to breed their first spring after hatching (11). Wilcox reported piping plovers lived for twelve years or more, and implied they were still reproductively active at an advanced age (02). During a single year, adults raise only 1 brood (02,11,33,56). If nests are destroyed, they will renest up to 3 times (11). Pairs fledge .3-2.1 chicks per year (02,30,31,33,51,56). Flemming showed that adults on undisturbed beaches fledged more chicks than those nesting on beaches with intense recreational activity (34). PARENTAL CARE: Piping plovers are a biparental species whose parental activities vary with location, year, and stage of the breeding season. In the spring, courtship, including copulation, begins soon after the birds arrive. Females lay an egg (average dimensions = 32.5 x 24.8 mm (33)) every other day until a 4-egg clutch is complete (02,03,05,33). Clutch size for an initial nest attempt is usualy four eggs (69). Copulations cease after the fourth egg is laid (03). Both males and females incubate clutches for 25-31 days (02,11,33,37,56). In Manitoba, partial incubation began with the laying of the first egg (03), while Cairns did not report the onset of incubation until the third egg was laid (33). Cairns reported equal division of incubation duties, but males in Manitoba assumed more incubation duties during laying and just prior to hatch (03,33). If the initial a clutch is destroyed early in the breeding season, the pair will often renest in the same vicinity (62,33). One female on Cape Cod was observed in five nesting attempts laying a total of 18 eggs (69). The precocial chicks hatch within a half day to a day of each other, and are able to feed themselves within hours. Brooding duties are shared by males and females, although females in Manitoba deserted broods as early as the first week after hatch (11). Broods generally remain on territories, but may expand their movements as they mature. Fledging time varies from 21 days in Manitoba and North Dakota (03, 37), to 27 days in Nova Scotia (33), to 30-35 days on Long Island (02). Males remain with broods until after fledging and have frequently been seen moving into post-breeding flocks with their chicks (11). POPULATION BIOLOGY: In 1985, pair counts for the U.S. population of piping plovers ranged between 930-1,065. Total species pair counts varied from 1,650 to 2,178 (28,30). There are no comprehensive historic numbers to compare with these figures, although major sites and regions (i.e., the Great Lakes) have suffered significant declines (28,30). Haig's genetic analysis of populations across North America (also discussed in the "N-Taxonomy" field) concluded that there was little difference between major regions, and that local populations appeared to be in Hardy-Wienberg equilibrium. Lack of heterozygosity occurred for some populations at some loci, but coefficients of inbreeding were not significant (11). At the individual level, Wilcox showed 13% of females and 28% of males lived to be 5 years or older (02). Twelve of his 288 birds Life History - 5 (DRAFT) - Life History Species PLOVER, PIPING Species Id ESIS103002 Date 14 MAR 96 achieved ages of 8-11 years. Data on adult mortality, population sex ratio's, and turnover rates are not known. Dispersal patterns are discussed below. SPECIES INTERRELATIONSHIPS: Piping plovers do not have a direct causal relationship with other species (excluding common nest predators such as gulls, raccoons, skunks, etc.), however their relationship with least terns (Sterna antillarum) is noteworthy. Historically, and currently, piping plovers nest in least tern colonies at a number of sites (28, 31,36). Both species inhabit river sandbars and sand pits on the Great Plains and Atlantic coast beaches. Threats to their success are similar, compounding problems associated with destruction of the habitat that they both occupy. In Nova Scotia, piping plovers nested among colonies of arctic terns (Sterna paradisaea) and common terns (Sterna hirundo) (33). Similarly, piping plovers at Lake of the Woods, Minnesota are nesting in the midst of a common tern colony (56,57). OTHER LIFE HISTORY DESCRIPTORS: An important aspect of developing management plans for any species is knowledge of their dispersal patterns. Breeding site fidelity ranges from 15% in Nova Scotia (33) to 68 percent in Manitoba and Minnesota (11,41,56,57). In Manitoba, males return more frequently than females. Return patterns to specific areas do not seem influenced by previous reproductive success (11,56). In Manitoba, adults that did not return to previous territories exhibited two patterns: If they had chicks hatch the year before, they returned to the same study site but changed territories; those that experienced nest failure the year before generally changed areas (11). Adults have been known to disperse as far as from Lake of the Woods, MN to northern Lake Winnipeg in consecutive years (11). Natal philopatry is low for piping plovers, ranging from 4.7 pct. return in New York to 20.2% return in Minnesota (02,11,56). In Manitoba, males and females return in equal numbers (11). Chick dispersal is difficult to document, although, a chick from southern Manitoba was found breeding at Long Point Ontario a year after hatch (11). Wilcox reported a chick from Penn Yan, NY bred at Long Point (02). Similarly, Pike observed a Long Point bird at Waugoschance Point in Michigan (41). Life History - 6

Piping plovers are a long-lived species with low annual reproductive success that utilize dynamic, highly ephemeral habitats throughout the annual cycle. There are no comprehensive, quantifiable population estimates for the species prior to 1980 (26), although Management Practices - 3 (DRAFT) - Management Practices Species PLOVER, PIPING Species Id ESIS103002 Date 14 MAR 96 early 20th century accounts report that shorebird hunting caused the first known major decline of the species (05). Since then, the factors discussed below have further contributed to the decline of the species. The culminating effects of these factors provided impetus for piping plovers to be declared endangered in Canada (27), threatened throughout it's U.S. range (except for the Great Lakes watershed where it is listed as endangered) (28), and placed on the Audubon Society's Blue List (29). Habitat alteration and destruction: The enormous loss of sandy beaches and other littoral habitats due to recreational or commercial developments, and dune stabilization in the Great Lakes region, Atlantic coast beaches, and Gulf of Mexico winter sites is responsible for some decline of the species (05,27,28,30,31,32). In the Great Lakes, historic sites have also been destroyed by high water levels eroding beaches (32). Where breeding does occur on Great Lakes and Atlantic coast sites, success is severely impacted by human disturbance. Vehicular and foot traffic (including raking of beaches for trash) destroys chicks and eggs. The mere presence of people on beaches (i.e., hiking, camping, near-by boaters) inhibits incubation and other breeding behavior, further decreasing reproductive success (27,28,33,34,31). Currently, numbers of piping plovers are low enough that destruction of any part of their habitat significantly impacts the species. It is critical to keep in mind that the status of winter and migratory habitats are not well understood. Damming and channelization of rivers has eliminated sandbar nesting habitat along hundreds of miles of rivers in the Dakotas, Iowa, and Nebraska. Untimely water releases from dams along sections of the Missouri River subject remaining sandbar habitat to alteration and flooding during the breeding season. The damming and withdrawal of water for irrigation and other purposes has altered water flows in rivers (such as the Platte) thus facilitating the establishment of dense vegetation on formerly productive nest sites (28,35,36,38). Although some saline wetlands in the northern Great Plains have been drained or modified, it is difficult to assess the impact of this activity. Prindiville reports freshening of water on saline wetlands in central North Dakota has decreased their quality as nesting habitat (37). Overutilization by man: As mentioned above, early 20th Century sport hunting may have severely impacted the survival of piping plovers (05). Currently, hunting may be a problem in Newfoundland (39) and the West Indies (40), but it is not evident in the U.S. Hunting in the Caribbean Region may be for subsistence purposes. As more research is carried out on the birds, scientists are becoming increasingly aware of piping plover's sensitivity to human presence, including the presence of biologists, on their territories (09). In the future, research activities may have to be more carefully monitored. Disease or predation: Disease has not been known to be a problem for piping plovers. Furthermore, eggs tested for contaminants in Michigan did not show positive results (although only a few eggs were tested) and further testing for contaminants should be stressed (41). Predation, however, has become a problem along Atlantic and Great Lakes beaches, as well as, saline wetlands in the prairies. Increased Management Practices - 4 (DRAFT) - Management Practices Species PLOVER, PIPING Species Id ESIS103002 Date 14 MAR 96 urbanization and use of beaches brought an increase in the number of unleashed pets, unnaturally high densities of gulls (Larus spp.), and other predators such as skunks and foxes (09,28,42). Since the 1940's, the raccoon has greatly expanded its' range on the northern Great Plains and has become a common nest predator (37,43). Cattle trampling of nesting habitat may also affect nest and chick success. Inadequate regulatory mechanisms: Federal recognition of the species' status by the U.S. and Canada in 1985 has improved protection of piping plovers (28,30). Development and implementation of recovery plans by both countries will assist in assuring protection of sensitive habitat for the species. Other natural or manmade factors: Detailed studies of habitat use by post-breeding piping plovers have not been carried out, however, preliminary data show that stabilization of barrier island sandflats may be severely impacting the species' winter habitat. An oil spill along the Texas coast did kill piping plovers, but the incident was short-lived (44). Dinsmore reviewed the impact of surface mining on piping plovers and concluded that there was potential for habitat destruction as well as enhancement in mining areas (45). Future threats: Future threats are similar to current problems, i.e., increased recreational/commercial development of beaches, wetland drainage, water level manipulation on rivers, increases in predators, lack of undisturbed nesting habitat, and stabilization of winter sites. The impact of agricultural runoff into wetlands, botulism (46), or other environmental contaminants has not been investigated, but may prove detrimental in the future. APPROVED PLAN: U.S. Fish and Wildlife Service. 1988. Atlantic Coast Piping Plover Recovery Plan. U.S. Fish and Wildlife Service, Newton Corner, MA. 77 pp. UNAPPROVED PLAN: A recovery plan is also under development for the Great Lakes/Northern Great Plains recovery region by the U.S. Fish and Wildlife Service, Twin Cites, MN. On the Atlantic Coast recommended actions for recovery include habitat protection and the elimination of human disturbance, the latter being the most important. Piping plovers are nesting and rearing young at a time when beaches are heavily used by people. The posting of beaches to eliminate human traffic is vital to recovery. Public education endeavors are also important to inform people who unknowingly disrupt plover breeding. In the Great Lakes region the piping plover is extremely rare and human disturbance is evident at most sites. The elimination of human access (including but not limited to the use of off-road vehicles) to nesting beaches is necessary for recovery. In the Northern Great Plains region human disturbance is less of a problem than elsewhere. Loss of riverine habitat continues to be a threat to the plover. Protection from habitat loss is most Management Practices - 5 (DRAFT) - Management Practices Species PLOVER, PIPING Species Id ESIS103002 Date 14 MAR 96 effectively accomplished by acquisition, instream flow conservation, restricting development, and manipulation of discharge from water control structures on waters where nesting occurs. Habitat management to maintain early stages of succession (i.e., beaches, suitable nesting sites, etc.) may be accomplished by controlling native and introduced vegetation or creating artificial habitat. The maintaining of water flow and controlling of water salinity in riparian and coastal habitats is essential to maintaining the habitat quality. Predation may be a threat to the plover in all three regions but this factor needs further investigation. If warranted the controlling of wild, domestic, feral, and introduced predators, especially at nesting sites, may be a desirable recovery task. Currently, many states on the Atlantic coast are undertaking public information programs and human use of some plover nesting areas is being curtailed. In Michigan, where most of the Great Lakes plovers nest, most public beaches are now fenced. Management Practices - 6
