Methods

This data set consists of 101 permanent 1 m?×?1 m (1-m2) quadrats located within southwestern ponderosa pine ecosystems near Flagstaff, Arizona, USA. Individual plants in these quadrats were identified and mapped annually for 19?years (20022020). The original chart quadrats were established between 1912 and 1927 to determine the effects of domestic livestock grazing on herbaceous plants and pine seedlings. Today these data provide opportunities to examine the effects of climate and land-use change on plant demography, population dynamics, and community processes. The foci of these metadata are 101 permanent 1-m2 chart quadrats from within the southwestern ponderosa pine ecosystems in northern Arizona, USA. All of these quadrats are located within 40 km of Flagstaff, AZ. They are distributed over multiple sites with varying parent materials and topography, and spanning the elevation range of the southwestern ponderosa pine forest type on the Coconino National Forest and the Fort Valley Experimental Forest (FVEF) (Bakker and Moore 2007, Laughlin et al. 2011, Strahan et al. 2015). The original location of each quadrat corner is permanently marked in the field with tagged angle iron or galvanized steel pipe, and the precise location was recorded with a GPS unit. During each growing season, all plants found on these quadrats are identified and mapped. The resulting maps are digitized into a geographic information system to facilitate calculations of individual plant and total basal cover and density. Exclosure in SAMPLE_DESC indicates whether the quadrat is within a livestock exclosure.
