If you are interested in using data from Niobrara, please read the Terms & Conditions prior to submitting your Data Request Form.

Data Request: In order to access the Niobrara Forest Dynamics Plot data, a "Data Request Form" must be completed. This form requires that the applicant agree to comply with "Terms and Conditions" for the use of Niobrara Forest Dynamics Plot Data as described here. Our goal is to make the Niobrara Forest Dynamics Plot data available to all researchers, managers, and students. But maintaining the Niobrara project requires enormous field effort and an ongoing financial commitment by several parties, and we thus require that the Principal Investigator (Sabrina Russo, of the Niobrara Plot be considered a collaborator on any project making use of the data and be included as co-authors on any articles or presentations, unless the Principal Investigator explicitly states otherwise.

Non-transferability: Prospective investigators are not permitted to share the Niobrara data with other parties not included on the Data Request Form.

Citation: Any publication that uses Niobrara data should include the following citations:

Bailey H. McNichol, Ran Wang, Amanda Hefner, Chris Helzer, Sean M. McMahon, and Sabrina E. Russo. Topographically driven microclimatic gradients drive patterns of structure and diversity in a semi-arid ecotonal forest. In preparation.

Copies of articles: Copies of manuscripts should be sent to PI Sabrina Russo ( prior to submission for publication. Once published, the PDF and any supplementary documents should be sent to Sabrina Russo and to

Limitation of Use: Prospective investigators are not permitted to use the Niobrara data for projects or analyses other than those explicitly described in the Data Request Form. A new Data Request Form must be submitted for any new use of the data. Prospective investigators are also not permitted to sell the data, nor use them in any way for commercial gain.

Data Citation: Any publication that uses Niobrara data should state the specific version number of the data set used for analysis. This version number will be provided after the data request has been approved.

Acknowledgements: All publications that include the Niobrara plot data must acknowledge the institutions and funding that enabled the establishment of the plot with the following acknowledgement:

The 20.16-ha Niobrara Forest Dynamics Plot is a collaborative project of the University of Nebraska-Lincoln, the Nature Conservancy, and the Forest Global Earth Observatory (ForestGEO) of the Smithsonian Tropical Research Institute.  Funding to establish the Niobrara Forest Dynamics Plot came from Jacqueline B. Mars. The Niobrara Forest Dynamics Plot is part of ForestGEO, a global network of large-scale demographic tree plots.

The Niobrara Data Request Form is under construction.  

To submit a data request, please write to Niobrara PI, Sabrina Russo:  Please provide a description of your research project, the analyses you plan to perform on the data, and the data required (e.g. full dataset, specific census, species, diameter range, etc.).
