We have received outstanding news from our Massachusetts Coastal Waterbird Biologist, Carolyn Mostello. She shared the “Summary of the 2022 Massachusetts Piping Plover Census.” The grand total for Massachusetts breeding pairs of Plovers is a whopping 1033, up 6.8 percent relative to 2021. A total of 1,330 chicks was reported fledged for an overall productivity of 1.31 fledglings per pair.
The summary is prepared each year by the Natural Heritage and Endangered Species Program, a division of Mass Wildlife. The Summary is in pdf form and I am happy to email anyone the report if you are interested. Please leave a comment in the comment section and your email will pop up on my end. Thank you for your interest!
The following are some highlights from the Summary –
ABSTRACT
This report summarizes data on abundance, distribution, and reproductive success of Piping Plovers (Charadrius melodus) in Massachusetts during the 2022 breeding season. Observers reported breeding pairs of Piping Plovers present at 209 sites; 150 additional sites were surveyed at least once, but no breeding pairs were detected at them. The population increased 6.8% relative to 2021. The Index Count (statewide census conducted 1-9 June) was 1,013 pairs, and the Adjusted Total Count (estimated total number of breeding pairs statewide for the entire 2022 breeding season) was 1,033 pairs. A total of 1,330 chicks was reported fledged in 2022, for an overall productivity of 1.31 fledglings per pair, based on data from 98.6% of pairs.
INTRODUCTION
Piping Plovers are small, sand-colored shorebirds that nest on sandy beaches and dunes along the Atlantic Coast from North Carolina to Newfoundland. The U.S. Atlantic Coast population of Piping Plovers has been federally listed as Threatened, pursuant to the U.S. Endangered Species Act, since 1986. The species is also listed as Threatened by the Massachusetts Division of Fisheries and Wildlife pursuant to the Massachusetts’ Endangered Species Act.
Population monitoring is an integral part of recovery efforts for Atlantic Coast Piping Plovers (U.S. Fish and Wildlife Service 1996, Hecht and Melvin 2009a, b). It allows wildlife managers to identify limiting factors, assess effects of management actions and regulatory protection, and track progress toward recovery. In this report, we summarize data on abundance, distribution, and reproductive success of Piping Plovers breeding in Massachusetts in 2022, as observed and reported by a coast-wide network of cooperators.
METHODS
Monitoring and management of Piping Plovers and other coastal waterbirds in Massachusetts is carried out by wildlife biologists, seasonal shorebird monitors, beach managers, researchers, and volunteers affiliated with over 20 federal and state agencies, local municipalities, local and regional land trusts, private conservation organizations, and universities. Cooperators monitored 359 sites in Massachusetts in 2022 for the presence of breeding Piping Plovers.

Long term trends in breeding Piping Plover population size and productivity are shown in Figure 5. The five-year running average of productivity has declined overall since 1995; however, there is a noticeable increase since reaching a low point in 2013. Since 2018, the five-year average of productivity has been above the approximately 1.2 fledglings per pair thought to be necessary to maintain a stable population (Melvin & Gibbs 1996) 2, and the breeding population has increased dramatically over that period. In fact, since state-wide monitoring began, this is the first year where the estimated number of territorial pairs has exceeded 1,000 in the state of Massachusetts, far exceeding the goal of 625 pairs throughout New England identified in the Piping Plover Atlantic Coast Population Recovery Plan. Although the New England Piping Plover population has exceeded the population recovery goal, that is not the case for other regions along the Atlantic Coast.
