“…Finally, we compared predictions of the model with population trends for the Atlantic Coast metapopulation between 1991 and 1996, using results of the International Piping Plover Census (Haig and Plissner, 1993;Plissner and Haig, 1997). We then determined an appropriate survivorship rate that gave the best ®t of the model to the census numbers for the entire metapopulation.…”

“…Piping plovers (Charadrius melodus) are a wide-ranging species for which extensive demographic data have been collected throughout their range during the past 15 years (summarized in US Fish and Wildlife Service, 1988bService, , 1996Haig, 1992). In addition, two complete international censuses of both breeding and wintering ranges have been conducted in the past decade (Haig and Plissner, 1993;Plissner and Haig, 1997), and annual monitoring eorts provide accurate breeding population estimates. Originally listed as threatened in 1978, the Committee on the Status of Endangered Wildlife in Canada declared the species endangered in 1985 (Haig, 1985).…”

, "Viability of piping plover Charadrius melodus metapopulations" (2000). USGS AbstractThe metapopulation viability analysis package, vortex, was used to examine viability and recovery objectives for piping plovers Charadrius melodus, an endangered shorebird that breeds in three distinct regions of North America. Baseline models indicate that while Atlantic Coast populations, under current management practices, are at little risk of near-term extinction, Great Plains and Great Lakes populations require 36% higher mean fecundity for a signi®cant probability of persisting for the next 100 years. Metapopulation structure (i.e. the delineation of populations within the metapopulation) and interpopulation dispersal rates had varying eects on model results; however, spatially-structured metapopulations exhibited lower viability than that reported for single-population models. The models were most sensitive to variation in survivorship; hence, additional mortality data will improve their accuracy. With this information, such models become useful tools in identifying successful management objectives; and sensitivity analyses, even in the absence of some data, may indicate which options are likely to be most eective. Metapopulation viability models are best suited for developing conservation strategies for achieving recovery objectives based on maintaining an externally derived, target population size and structure. #

“…The 1991 census indicated that more than 80% of the Canadian prairie population resides in Saskatchewan, of which 24% (representing approximately 5 % of the North American population) breeds at Lake Diefenbaker (Haig and Plissner 1993). Fluctuations in water level at this lake have caused problems for Piping Plovers breeding there in past years.…”

We studied habitat selection by Piping Plovers (Charudrius melodus) at Lake Diefenbaker, Saskatchewan, during the 1992 and 1993 breeding seasons. Habitat selection was investigated at three levels: beach, territory, and nest site. Nest beaches had significantly more gravel substrate than non-nest beaches ( F I l , l l I = 21.52, p < 0.01). There was no significant difference in width between nest and non-nest beaches. All Piping Plover nests were located on gravel, though this substrate only accounted for approximately 43% of nest beach area. Nest sites were significantly farther from the nearest water (FI,, ,,,, = 12.24, p < 0.0 l), the main water body (Fl ,, ,,, = 6.55, p < 0.05), and had significantly more stones (FI,.,,,, = 10.98, p < 0.01) and rocks (Z = 2.93, p < 0.01) than random sites. Distance to the nearest water source, number of stones per square metre, and distance to the vegetation line were the three variables used by the stepwise discriminant function analysis to correctly classify 41.8% of nest sites and 87.1 % of random sites. This was still significantly better than chance (Z = 3.66, p < 0.01). The low percentage of correctly classified nest sites may indicate that some plovers at this lake used nest sites on lower quality substrate. Flooded nests were significantly closer to water than successful nests and depredated nests were closer to the vegetation line than successful nests.RCsumC : Nous avons etudie I'habitat du Pluvier siffleur (Churudrius melodus) au lac Diefenbaker, Saskatchewan, au cours des saisons de reproduction de 1992 et 1993. Le choix de I'habitat a ete etudie sous trois aspects, le choix d'une plage, le choix d'un territoire et le choix d'un site de nidification. Les plages choisies pour la nidification comportaient significativement plus de gravier que les plages sans nids (F,, ,, ,, = 2 1,52, p < 0,Ol). 11 n'y avait pas de difference significative de largeur entre les plages avec nids et les plages sans nids. Tous les nids etaient construits sur du gravier, meme si ce substrat ne constituait que 43% environ de la surface des plages avec nids. Les sites de nidification ktaient significativement plus eloignes de la masse d'eau la plus proche ( F l l , 1 8 1 1 = 12,24, p < 0,Ol) ou de la masse d'eau principale (F,,,,,,, = 6,55, p < 0,05) et comportaient significativement plus de cailloux (F,,,,6,1 = 10,98, p < 0,Ol) et de pierres (Z = 2,93, p < 0,Ol) que des sites choisis au hasard. Au cours d'une analyse par itapes des fonctions discriminantes, trois variables, la distance jusqu'a la masse d'eau la plus proche, le nombre de cailloux par metre carre et la distance jusqu'a la ligne de vegetation, ont permis de classifier correctement 41,8% des sites de nidification et 87,1% des sites aleatoires. I1 s'agit la d'un resultat plus satisfaisant que la determination au hasard (Z = 3,66, p < 0,Ol). Le faible pourcentage des sites de nidification classifies correctement peut signifier que certains pluviers de ce lac utilisent des sites a substrat de qualite moindre. Les nids inondks eta...

“…A complete winter survey of Piping Plovers was conducted in (Haig and Plissner 1993Haig et al 2005;Elliott-Smith et al 2009). In 2001, they reported 2,389 piping plover during the winter, but 5,945 adults were counted during the breeding season (Haig et al 2005).…”
