Quadrat of the Day

Our goal is to make the data from the WFDP available to the broadest possible community of researchers. As our effort is still in its early days, we are focusing our efforts on genuine research collaborations leading to co-authorship in peer reviewed publications. Collaborations that assist us with our existing program of field sampling and analysis are especially valued. Contact PI Jim Lutz to discuss access to data.

The WFDP data are stored on servers at the Smithsonian Center for Tropical Forest Science.

Data Policies

Data requests:
All requests for WFDP data or access to the plot must be in writing. Requests should include the list of people requesting data, the topic and scope and schedule of the research, and the target publications. Prospective investigators should resubmit applications for each substantially different project. Students who desire access to the data should submit their request through their adviser. Access to the WFDP requires an on-site orientation by the Principal Investigators. Facility access must also be coordinated with the Wind River Field Station.
Access the WFDP or WFDP data is granted only to the specific people requesting data only for the purpose originally requested and for the time period originally requested. Redistributing or sharing data with anyone not included on the application is not allowed. Some journals (notably Ecological Monographs) now require that all source data be archived in a publically available repository. We will only allow archiving of data at a journal website if we have already publically released the data (generally after the completion of the following census). Potential collaborators should assume that it will not be possible to publish in a venue that requires public posting of the raw data.
Maintaining the Wind River plot requires enormous field effort and an ongoing financial commitment. We therefore require that the Principal Investigators be included as co-authors on publications produced from research conducted in the WFDP or using WFDP data.
Prior to submission, manuscripts and reports should be sent to the Principal Investigators for review (assuming that they are not sent to the Principal Investigators in their role as co-author). Once published, copies all publications and reports should be sent to the Principal Investigators to be included in the WFDP library and added to the WFDP web site (if allowed by applicable copyrights).

Publications using the WFDP data should include the citation to the plot establishment paper: Lutz, J. A., A. J. Larson, J. A. Freund, M. E. Swanson, K. J. Bible. 2013. The importance of large-diameter trees to forest structural heterogeneity. PLOS ONE 8(12): e82784. doi:

Publications using the WFDP data in conjunction with the 1999 demographic data should additionally cite: Lutz, J. A., A. J. Larson, T. J. Furniss, J. A. Freund, M. E. Swanson, D. C. Donato, K. J. Bible, J. Chen, and J. F. Franklin. 2014. Spatially non-random tree mortality and ingrowth maintain equilibrium pattern in an old-growth Pseudotsuga-Tsuga forest. Ecology 95(8): 2047-2054. doi:

Research Policies
We welcome proposals to collect new and different types of data within the WFDP and to build a rich data set for this forest. Our work is conducted under a research permit approved by the US Forest Service in conjunction with the US Forest Service Pacific Northwest Research Station. Any field work must either fall within the scope of our existing research permit or must be approved by the Gifford Pinchot National Forest, the US Forest Service Pacific Northwest Research Station, and the University of Washington Wind River Field Station. Any data collection or installation of equipment within the WFDP imposes an overhead on the project and the PIs, and we regret that we don’t have the resources to do specialized field work for affiliated researchers unless projects can pay their own way.

Destructive sampling and manipulative research is not allowed within the WFDP, but manipulative experiments can be implemented outside the Research Natural Area.
