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.
|Identification||Primary data||Data products||Site measurements|
|stem number||stem length in fall and|
|browsing intensity||spatial coordinates (utm)|
|plant number||stem length in fall||production||snow depth and snow
|site number||plant height||water table depth at|
|date||surveyed location of plant camera trap images||classified images||growing season start and end growing season precipitation
soil moisture and
temperature water table depths at 4-8 locations
