Audubon Florida has led conservation work in the state since 1900. Its current statewide figures include 139,000 members and supporters, 100 staff members, 44 local independent chapters, and 525 bird species protected, according to the Audubon Florida page. The statistics below combine those organization-wide measures with results from Audubon monitoring and stewardship programs, especially the 2024 beach-nesting bird season.

Organization-wide reach
The basic scale of Audubon Florida is measured in people, chapters, staff, and species. The Audubon Florida page lists 139,000 members and supporters. It also lists 100 staff members and 44 local, independent chapters engaged in grassroots conservation. Together, those figures describe a network that combines statewide staff capacity with locally organized activity.
The same page lists 525 bird species protected. A separate Audubon Birds of Florida page says the organization protects more than 500 bird species in Florida. These two figures use different wording: 525 is the listed organization figure, while “more than 500” is the broader statement on the bird-focused page. They should not be treated as separate species totals.
Audubon’s history in Florida reaches back to 1900. One historical milestone was support for expanding Big Cypress National Preserve by 115,000 acres, according to the History of Audubon in Florida. That acreage is a historical conservation figure, not a current estimate of Audubon-owned land.
Another recurring measure of public participation comes from Christmas Bird Counts. More than 2,000 people participate in over 60 Christmas Bird Counts in Florida each year, according to the History of Audubon in Florida. The figure describes annual participation and count locations; it is not a total number of birds observed.
Coastal and waterbird conservation
Audubon Florida’s Coastal Stewardship program protects sea, shore, and wading birds at more than 300 sites across Florida, according to the Audubon Florida page. The 2024 Audubon Florida Beach-nesting Birds Nesting Season Summary uses a similar operational scale, reporting that Audubon monitors and stewards more than 300 nesting sites across the Gulf and Atlantic coasts.
The Florida Coastal Islands Sanctuaries program has a long-running geographic footprint. The History of Audubon in Florida says it protects about 50,000 breeding pairs of birds from Tarpon Springs to Sarasota, along with five islands near West Palm Beach. The 2024 nesting-season summary records around 10,300 nesting pairs of wading birds in the sanctuaries during 2024. These figures refer to different bird groupings and contexts: the historical program description covers breeding pairs across the sanctuary footprint, while the 2024 figure is a reported annual count of wading-bird nesting pairs.
The 2024 report also provides statewide comparison estimates for five beach-nesting species. Audubon’s monitored counts are site-based, while the Florida totals are estimated breeding populations.
| Species | 2024 monitored count | Estimated Florida breeding population |
|---|---|---|
| Black Skimmer | 4,898 | 7,000 |
| Snowy Plover | 124 | 400 |
| Least Tern | 2,658 | 13,000 |
| American Oystercatcher | 110 | 500 |
| Wilson’s Plover | 206 | 900 |
The table should be read as a monitoring snapshot alongside statewide estimates, not as a direct population trend. The monitored count covers Audubon sites, whereas each estimated Florida population covers the state and is labeled as an estimate in the 2024 ANNUAL SUMMARY.
Florida Scrub-Jay monitoring
Florida Scrub-Jay statistics show why repeated field surveys matter. The species’ population has declined by 90% since the early 1900s, according to “Volunteers are Providing the Data Needed to Manage Florida’s Endemic Bird.” The same source reports that 70% of Florida Scrub-Jays live at one of four large habitat strongholds. The remaining 30% survive in scattered fragments of scrub habitat.
Jay Watch surveys 46 to 50 sites each year. Volunteers spend three days at each site inventorying populations. Those figures describe the survey design and annual geographic coverage, rather than a statewide count of every scrub-jay.
The Cross Florida Greenway example gives the monitoring numbers a site-specific context. The property involved 446 acres and had eight scrub-jays when restoration began. The restored Greenway site is 1,000 acres, and Jay Watch used five volunteer teams there. Because the acreage measurements describe different stages or scopes of the example, they should not be combined into a single change calculation.
Volunteer effort was also quantified in 2025. About 150 volunteers participated in Jay Watch surveys, contributing more than 1,200 hours of work, according to “Volunteers are Providing the Data Needed to Manage Florida’s Endemic Bird.” Those figures indicate the scale of the survey workforce in 2025; they do not state how many scrub-jays were counted.
Beach-nesting bird counts
The 2024 Audubon Florida Beach-nesting Birds Nesting Season Summary records results by species and location. At Tyndall Air Force Base, nine Snowy Plover chicks and 27 Wilson’s Plover chicks left the beach. Navarre Beach saw 120 Least Tern chicks and 50 Black Skimmer chicks fledge in 2024. In the Eastern Panhandle, American Oystercatchers fledged chicks from three remote islands.
Rooftop nesting was another part of the 2024 program. Panhandle rooftops hosted Least Terns at 10 sites. Tampa Bay had 22 active rooftops, and rooftop monitoring recorded seven American Oystercatcher pairs with seven fledged chicks. The counts describe monitored nesting activity during the 2024 season, not all rooftop colonies in Florida.
Several named coastal sites reported larger or smaller local outcomes. Huguenot Memorial Park produced more than 1,000 new Royal Terns and more than 100 Brown Pelicans. Anastasia State Park fledged more than 100 Least Tern chicks, Fort Matanzas fledged around 50 Least Terns, and South Lido Key produced 140 fledged Least Tern chicks.
Black Skimmer colonies in Pinellas and Sarasota counties produced 665 fledged chicks in 2024. In Southwest Florida, the Second Chance Critical Wildlife Area had 600 Black Skimmers fledge 150 chicks. These are location-specific results and should not be added to the statewide estimated breeding population in the comparison table.
2024 nesting and fledging results
The 2024 summary includes a detailed Carlos Pointe Beach snapshot. The site supported 1,333 adult Black Skimmers and 418 adult Least Terns. It produced 231 Black Skimmer fledglings and 200 Least Tern fledglings. Adult counts and fledgling counts represent different measures, so the figures show site activity without establishing a survival rate.
Southwest Florida Least Terns fledged 100 chicks from 168 nests, according to the same report. That report also states that 600 Black Skimmers fledged 150 chicks at the Second Chance Critical Wildlife Area. Both results are tied to named Southwest Florida monitoring areas and the 2024 season.
The 2024 report’s statewide monitored totals are useful for identifying the relative scale of the five focal species. Black Skimmers had the largest monitored count at 4,898, followed by Least Terns at 2,658. Wilson’s Plovers numbered 206, Snowy Plovers 124, and American Oystercatchers 110 at monitored sites. The estimated statewide totals differ substantially by species, particularly for Least Terns, whose estimated Florida breeding population is 13,000.
The report also documents nesting success in places where birds share working or developed landscapes. The 10 Panhandle rooftop sites and 22 active Tampa Bay rooftops show that the monitored program includes built environments as well as beaches and islands. No single site count represents the total Florida population, because the report presents local observations within a broader stewardship network.
Water, shoreline, and habitat projects
Audubon scientists in Southwest Florida have monitored water levels for 67 years, according to “Fixing Water Levels for Wood Storks.” The organization’s water-level data show drier conditions overall. In the 2024 Water Year Report, total rainfall was 13 inches lower than the average since 2000. The delayed dry-down occurred on May 30, 2024, compared with an average dry-down date of April 10.
Those dates are important because they distinguish a measured 2024 event from a long-term average. May 30 is the reported 2024 dry-down date, while April 10 is the average date. The rainfall comparison likewise sets the 2024 total against the average since 2000; it is not a forecast.
Living shoreline work provides another set of physical project measures. Audubon Florida installed 1,800 additional feet of pH-neutral living shoreline in December 2024, bringing total installed living shoreline to 10,000 feet, according to the 2024 ANNUAL SUMMARY. The project protects habitat for 18 bird species.
Earlier rooftop protection work is quantified in the 2023 ANNUAL SUMMARY. Audubon installed 2,750 feet of fencing to protect rooftop chicks and installed 198 chick shelters for rooftop birds. It banded 168 healthy Least Tern juveniles from 16 nesting rooftops. Fifty of those Least Terns were later resighted 347 times. The resighting figure counts observations, not necessarily 347 individual birds, because the source states that 50 birds were resighted 347 times.
Taken together, these figures show several distinct ways Audubon Florida measures conservation: organizational participation, protected species, monitored sites, annual bird counts, fledgling production, volunteer hours, water conditions, shoreline length, and follow-up observations. Each statistic is most useful when its date, geography, and measurement type remain attached to it.
