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.

The data were subsequently spot checked by several scientists to ensure there were no unusual values and that all entries were logical. No erroneous outliers or duplicate entries have been detected in the dataset. Although these data have been processed successfully on a computer system at the U.S. Geological Survey (USGS), no warranty expressed or implied is made regarding the display or utility of the data for other purposes, nor on all computer systems, nor shall the act of distribution constitute any such warranty. The USGS or the U.S. Government shall not be held liable for improper or incorrect use of the data described and/or contained herein. The dataset is considered complete for the information presented, as described in the abstract. Users are advised to read the rest of the metadata record carefully for additional details. This dataset contains morphometric information from Burmese pythons collected year-round from an invasive population in southern Florida between 1995-2021 through nonprofit organization, Federal, and State funded research, removal, volunteer, and management programs and private individuals. Data were collected in the field or laboratory by numerous entities including biologists, paid python removal contractors, python removal volunteers, and members of the public who encountered pythons incidentally. These data were compiled by USGS and NPS biologists over many years into one .csv file associated with this data release.Data were collected from every specimen based on specimen condition, staffing, and data needs over the years. Due to the nature of the collection of the dataset, there is variation in dataset completeness based on the data that were collected at the time. As the dataset reflects opportunistic captures and surrenders, these data may not represent the entirety of the populations’ variation or demographic patterns. The dataset includes python identification information, capture information, morphometric data, and/or necropsy data including reproductive information from 4,007 specimens. 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. We recorded location of capture (UTM WGS84), date of capture/death, sex, weight (grams), snout vent length (SVL, cm), tail length, tail completeness (intact or broken/incomplete), total length, reproductive status based on gonad developmental state (see below), and/or number of most developed ovarian structure/oviductal eggs. We recorded reproductive data for pythons during necropsies and classified reproductive status using a visual assessment of the specimens’ most developed gonadal structure (following Aldridge 1979; https://www.jstor.org/stable/3891696). Gonad developmental state categories included: undeveloped (no follicles/oviductal eggs or testes categorized or identified), primary follicles (small, preliminary or pre-vitellogenic oocytes), secondary follicles (pre-ovulatory vitellogenic follicles), oviductal eggs (post-ovulatory/ovigerous), flaccid testes (testes distinguished but not turgid), semi-turgid testes, and turgid testes. 20220901 Universal Transverse Mercator 17 0.9996 -81.0 0.0 500000.0 0.0 coordinate pair 0.6096 0.6096 meters WGS_1984 WGS 84 6378137.0 298.257223563 FL Specimen Management Database Pre-2022PYMO.csv Comma Separated Value (CSV) file containing data.
