A dataset listing Florida counties by population for 2024.

During the past century, river and tidal creeks through the coastal wetlands of the Everglades have filled with sediment and vegetation of surrounding landscapes to the point that many have greatly diminished or disappeared entirely. Restoration plans are under consideration to redirect additional freshwater inflow from the Everglades to open and sustain these waterways to a level that closely resembles historic patterns. In the last 100 years, requirements for water supply and flood protection for urban areas and agriculture in South Florida have resulted in the construction of an extensive canal system to prompt drainage of water into the Atlantic Ocean rather than allowing seasonal seepage through the Everglades and Florida Bay. Water diversions and excessive nutrients and contaminants within the Everglades have decimated bird populations and driven the Florida panther to the brink of extinction. In Florida Bay, declines in sea grasses have resulted in decreasing water clarity, degradation of the food web, and resultant declines in fish populations. The data will be used for hydrodynamic modeling for determining MFL, and for PES scientific studies to improve society's understanding of the environment and assist in the sustainable use, protection, and restoration of the Everglades and other ecosystems within the Southwest region of Florida. This report serves as an archive of processed swath bathymetry data that were collected in Little Shark, Broad, Harney, Huston, Turner, Chatham, and Lopez. All rivers are located within the boundaries of Everglades National Park in 2004. All rivers are located within the boundaries of Everglades National Park in south Florida. Geographic information system data products include a XYZ data set divided by rivers and USGS quadrangle boundaries. Additional files include formal Federal Geographic Data Committee metadata.

New York was the most populous state in the union in the year 1900. It had the largest white population, for both native born and foreign born persons, and together these groups made up over 7.1 million of New York's 7.2 million inhabitants at this time. The United States' industrial centers to the north and northeast were one of the most important economic draws during this period, and states in these regions had the largest foreign born white populations. Ethnic minorities Immigration into the agricultural southern states was much lower than the north, and these states had the largest Black populations due to the legacy of slavery - this balance would begin to shift in the following decades as a large share of the Black population migrated to urban centers to the north during the Great Migration. The Japanese and Chinese populations at this time were more concentrated in the West, as these states were the most common point of entry for Asians into the country. The states with the largest Native American populations were to the west and southwest, due to the legacy of forced displacement - this included the Indian Territory, an unorganized and independent territory assigned to the Native American population in the early 1800s, although this was incorporated into Oklahoma when it was admitted into the union in 1907. Additionally, non-taxpaying Native Americans were historically omitted from the U.S. Census, as they usually lived in separate communities and could not vote or hold office - more of an effort was made to count all Native Americans from 1890 onward, although there are likely inaccuracies in the figures given here. Changing distribution Internal migration in the 20th century greatly changed population distribution across the country, with California and Florida now ranking among the three most populous states in the U.S. today, while they were outside the top 20 in 1900. The growth of Western states' populations was largely due to the wave of internal migration during the Great Depression, where unemployment in the east saw many emigrate to "newer" states in search of opportunity, as well as significant immigration from Latin America (especially Mexico) and Asia since the mid-1900s.

Layer will help District staff and utilities identify lodging facilities and associated rooms within their retail service area boundary. It will assist in the calculation of functional tourist population for the year of interest. Functional tourist population is the estimated average annual number of tourists in the service area per day. Please note that some of these lodging facilities are self-supplied.

This project focuses on West Indian manatee (Trichechus manatus latirostris) distribution, habitat use and movement patterns to address questions important to understanding the ecology of several communities in southwest Florida used by manatees, including offshore seagrass beds, estuarine bays, tidal creeks, and rivers. A large proportion of the southwest Florida manatee population occurs throughout the Everglades National Park (ENP) and north into the Ten Thousand Islands (TTI) National Wildlife Refuge.

Aerial surveys and telemetry data from tagged manatees provide a valuable means of documenting the response of manatees to natural and human-induced fluctuations in freshwater inflow. This information, combined with water quality data obtained from monitoring stations, will be incorporated into the manatee ATLSS model which will be used to better understand and predict manatee response to different restoration scenarios.

The major objectives of the study are to determine relative abundance, distribution, movements, and habitat use of manatees associated with coastal waters and rivers in the western everglades, and to develop an individual-based ATLSS model to predict manatee response to changes in hydrology achieved by the Southern Golden Gate Estates (SGGE) project specifically, and more broadly by the Comprehensive Everglades Restoration Plan. Work has primarily focused on the TTI/SGGE restoration area, with some data also collected from tagged manatees using the southwest portion of ENP. Data for this project is collected via: satellite telemetry and tracking of individuals using a specially designed Global Positioning System (GPS) tag. Data will be used in developing the predictive manatee model which will integrate with the TIME model.

This research investigated observations of an increase in a predatory mite within galls for a screenhouse mass rearing colony. The survey consisted of counted the galls on 5 haphazardly selected plants and then dissecting 5 galls for each plant. The number of Floracarus perrepae biological control mites and the number of predatory mites were recorded for each gall. The survey was intended to run a full early starting 9/29/2021, but it concluded early in July 2022 when the screenhouse became too hot for a colony to be maintained there. Predatory mite presence is correlated with a reduction in F. perrepae numbers. Sequenced samples of predatory mite from the colony and indicated that the predatory mite is Amblyseius rematavensis.Partially funded by the USDA through the Comprehensive Everglades Restoration Plan (CERP) (USDA agreement 58-6032-1-001), through the Southwest Florida Water Management District (USDA agreement 58-6032-3-003).

Historical records indicate that oyster reefs were once significant features of the waters of the Atlantic Ocean and the Gulf of Mexico, at times presenting significant hazards to navigation (Cake 1983, Mann et al. 1996). Many Florida estuaries have previously supported a thriving oyster industry (Ingle & Whitfield 1968). Recent decades, though, have witnessed dwindling oyster populations throughout the Atlantic and Gulf coasts. For example, it has been estimated that at one time oysters could completely filter the water volume of Chesapeake Bay in only 3.3 days; current populations take more than a year to do so (Newell 1988). Similarly, records from Southwest Florida suggest that oyster growth and distribution has decreased drastically since the 1960s (Chamberlain & Doering 1998). Factors responsible for this overall decline may include overfishing and associated habitat destruction, a shortage of suitable substrate, disturbances such as dredging, reduced water and habitat quality, alteration of natural water flow and salinity patterns, natural and introduced predators, and disease (Coen et al. 1999a, Lenihan et al. 1999, Volety et al. 2000). The protozoan parasite Perkinsus marinus has devastated oyster populations in the Atlantic (Burreson & Ragone-Calvo 1996), where it is the primary pathogen of oysters, as well as in the Gulf of Mexico (Soniat 1996). Andrews (1988) estimated that P. marinus can kill ~80% of the oysters in a bed. The distribution and prevalence of P. marinus is influenced by temperature and salinity with higher values favoring the disease organism (Burreson & Ragone-Calvo 1996, Soniat 1996, Chu & Volety 1997). Field and laboratory studies indicate that P. marinus exerts severe pressure on growth, survival, and energy reserves of oysters, thereby limiting reproduction and recruitment (Paynter & Burreson 1991, Volety & Chu 1994, Volety et al. 2000). Extensive research has been conducted on various aspects of physiology, biochemistry, reproduction, and recruitment (see Kennedy et al. 1996) in the eastern oyster (Crassostrea virginica); however, oyster growth, reproduction, recruitment, and survival depend on a multitude of complex, interacting, local factors such as substrate, estuarine circulation, food availability, temperature, salinity, and genetics (e.g., Kennedy & Boicourt 1981, Livingston et al. 2000). Few studies from Southwest Florida have examined oyster health, survival, or the prevalence of P. marinus in relation to environmental factors and water quality (Quick & Mackin 1971, Christensen et al. 1998). Our research to date on oyster reef development and oyster productivity within human-altered watersheds within the Ten Thousand Islands of Southwest Florida suggests that watershed alteration influences patterns of oyster recruitment and growth as well as of oyster-reef distribution (Savarese & Volety 2001a,b, Volety et al. 2001, Savarese et al. 2002, Savarese et al. 2004). For example, estuaries presently receiving more freshwater than the natural pre-alteration conditions allowed (e.g., Faka Union estuary downstream of South Golden Gate Estates) have fewer oyster reefs, lower living oyster densities, and greater mortality of young oysters than do relatively pristine, neighboring estuaries. Our research in the Caloosahatchee Estuary suggests that both organism abundance and density vary spatially within the estuary, with higher values occurring upstream, at lower salinities (Tolley et al. 2002a, b). Highest organism abundances occur at sites with greater densities of living oysters. In contrast, species diversity and richness are greater downstream at higher salinities. In addition to salinity effects, oyster distribution, growth, and reproduction are affected by water flow. Oysters require swift moving currents to acquire food and for the distribution of gametes and larvae (Carriker 1951, 1986, Wood & Hargis 1971, Kennedy 1996). Reefs typically form in regions of an estuary that not only have the most desirable salinity, but also are exposed to strong tidal currents (Kennedy 1996, Shumway 1996). Anecdotal evidence suggests that oyster reef location (i.e., immediately up- or downstream from an estuarine flow-way constriction) and shape (i.e., with the long axis perpendicular to flow direction) are dictated by tidal flows (Savarese unpublished data). Unfortunately, this is one aspect of reef distribution that has not been explored in Southwest Florida. Appropriate water quality (e.g., salinity) and flow regime both must be considered when assessing estuarine health and when planning estuarine restoration projects (Volety et al. 2003). The Southwest Florida community of estuarine scientists and managers has recognized the significance of our research findings by establishing oyster health and reef productivity as measures of performance of estuarine restoration for numerous watersheds throughout the Big Cypress Basin’s jurisdiction.

Lygodium microphyllum (Lygodiaceae) is an invasive vine that has invaded natural areas in Florida. The USDA-ARS Invasive Plant Research Laboratory mass rears and releases two biological control agents to help manage L. microphyllum infestations, one is the moth Neomusotima conspurcatalis (Lepitoptera: Crambidae). As part of the mass rearing of the biological control agent surveys are completed to monitor agent populations and to quantify their impact on L. microphyllum growth. This dataset contains the results of random search surveys from April 2018 to Sept 2021. In April 2018, permanent transect start points were established for timed searches at four monitoring sites to quantify agent impact. Time searches utilizes two surveyors that non-systematically explored the L. microphyllum patch for 15 minutes (for a total of 30 minutes) looking for and inspecting for feeding damage, larvae, and adults.​ To determine whether biological control agents establish self-perpetuating field populations in addition to the timed searches monthly monitoring of N. conspurcatalis capsule traps that incorporated the pheromones from pupae were deployed. Use of the capsule traps was suspended in March of 2020.Partially funded by the USDA through the Comprehensive Everglades Restoration Plan (CERP) (USDA agreement 58-6032-1-001), through the through Southwest Florida Water Management District (USDA agreement 58-6032-3-003), and through the Florida Fish and Wildlife Conservation Commission (USDA agreement 58-6032-9-008).

This dataset contains morphometric information from Burmese pythons collected from an invasive population in southern Florida between 1995-2021. Scientists from the U.S. Geological Survey and the National Park Service curated this dataset as a repository for records of Burmese pythons found on or nearby federal lands in southern Florida, including Everglades National Park, Big Cypress National Preserve, Biscayne National Park, and Crocodile Lake National Wildlife Refuge. As such, numerous entities actively or incidentally involved in python research or management activities contributed specimens and/or data to this dataset, including but not limited to the U.S. Geological Survey, National Park Service, U.S. Fish and Wildlife Service, University of Florida, Conservancy of Southwest Florida, Florida Fish and Wildlife Conservation Commission, South Florida Water Management District, volunteers, and members of the public. The dataset includes python identification information, capture information, morphometric data, and necropsy data. The structure of the dataset is such that every row pertains to a single date that data were collected from a single python so that serial captures and morphological data collected from unique individuals can be tracked across time via different rows.
