The Terrestrial Ecology Lab is highly collaborative and encourages data sharing to promote synthetic analyses and open access to data. Our data sharing and public access policies are consistent with Creative Commons Attribution 4.0 International (CC-BY 4.0), a public license that makes the data freely available (i.e. use without permission) provided the source of the data are attributed properly, and that the user does not claim an endorsement by the Smithsonian Institution for their specific application of the data (unless stated otherwise). The policy was adopted because the data are collected by both US Federal and non-Federal employees, making the application of Federal copyright law to the data unclear. CC-BY 4.0 is used by Federal and State agencies, and non-profit organizations (https://creativecommons.org/licenses/by/4.0/).

Although permission to use the data is not required, we encourage you to discuss your intended application of the data with us as there are often nuances to the data that may complicate your analyses. Please contact Dr. John Parker (parkerj@si.edu, 443-482-2221) or Jamie Pullen (pullenj@si.edu, 443-482-2398) with further questions.
