Amphibian imports into the United States from 1999 to 2021

Shared here are data and code to support the manuscript: "Despite Lacey Act regulation, ongoing amphibian trade into the United States threatens salamanders with disease." A project overview is provided in the GitHub repository, but, in brief, this work required the compilation and cleaning of the United States Fish and Wildlife Service's Law Enforcement Management Information System (LEMIS) data in order to generate a complete time course of amphibian imports to the United States from 1999 to 2021. Others pursuing data reuse will most likely be interested in the full, cleaned amphibian import dataset (in CSV format) contained within these project files, which is named harmonized_amphibian_LEMIS_1999_to_2021.csv. Information regarding the LEMIS data, including detailed description of the data fields, can be found in Eskew et al. 2020, "United States wildlife and wildlife product imports from 2000–2014".
