DATA OVERVIEW

Plant and Site Measurements
The data are structured hierarchically: measurements are taken at the level of stems within plants, plants within sites, and sites. The data include primary measurements taken in the field or lab as well as data products derived from the primary data. Plant and site measurements include classes of data corresponding to different response types: growth and browsing, ground water use, water stress, photosynthesis, and identification of the species of browsers. Site characterization include meteorological measurements, soil moisture and temperature, and data on depths of water tables. All data is referenced by identification variables that will link the different responses and site characterizations to specific plants and sites. We illustrate the data hierarchy for the growth and browsing data class in Table 1 and Figure 1.  Individual data files are summarized and available for download here.

DATA MANAGEMENT PLAN

Data storage and archiving
Raw data, data products, and metadata will be stored in three locations:
1. Data that have been error-checked and are ready for use by the community will be stored in the Colorado State University Libraries Digital Repository. The Digital Repository archives data indefinitely with industry standard backup. Access is open.
2. A GitHub repository will be used to provide version controlled access to project files for quality control, data reduction, and analysis. Project personnel will have read and write access. The public will give allowed read-access with a warning that data are not yet ready for analysis.
3. Local GitHub repositories will be maintained on computers of PI’s graduate students. All files will be backed up at least daily to multiple external hard drives.
Access to data
We will make all collected and derived data accessible to the scientific community and interested public using the Colorado State University Libraries Digital Repository , a service jointly operated, and managed by the CSU Libraries and the Department of Academic Computing and Networking Services. Data will be archived and made accessible to the public at no cost to the project. The PI(s) will assure quality of all data and will supply metadata.
Metadata will be reviewed and supplemented as needed by librarians with expertise in data and metadata organization and management. The CSU Digital Repository provides an exceptionally high-quality environment for data accessibility and preservation. The CSU Libraries faculty and staff are experts in operating, managing, and sustaining digital data in formal repositories.
Data archive and access Policy
1. We affirm that field measurements, laboratory measurements, data products, model output, and R code for data transformation arising in part or whole from this research and already ‘made public’ via scientific publication(s), will be permanently archived and freely available for access on the web by all interested people. The exception to this policy will be data that need to be maintained to protect well being and safety of animals studied by our collaborators.
2. In cases where students or project investigators have collected data or field samples, or created derived datasets from field, laboratory or model output, but data and analyses are still being prepared for publication, we will provide a ‘sole-access’ period of no more than 12 months from completion of data collection, after which time arrangements will be made for distribution as in (1). Completion of data collection means obtaining the final observations in a planned investigation.
3. Users of data associated with this project will be asked to appropriately acknowledge of the original funding source (NSF) and to consider, as appropriate, shared authorship with graduate students and senior investigators primarily responsible to collecting the data.
