We developed a vegetation classification and high-resolution vegetation map for Petroglyph National Monument, New Mexico, as part of the USGS Vegetation Characterization Program, a cooperative effort by the U.S. Geological Survey (USGS) and the National Park Service Inventory & Monitoring - Vegetation Mapping Program to classify, describe, and map vegetation communities in more than 280 national park units across the United States. The classification and map follow the guidelines and requirements of the national program, and are based on data collected from 499 field plots between 2007 and 2011 plus 469 independent survey points to assess the accuracy of the map and completeness of the classification.

The Missouri Resource Assessment Partnership (MoRAP) of the University of Missouri, in conjunction with the Oklahoma Biological Survey of the University of Oklahoma, produced a vegetation and landcover GIS data layer for the eastern portions of Oklahoma. This effort was accomplished with direction and funding from the Oklahoma Department of Wildlife Conservation and state and federal partners (particularly the Gulf Coast Prairie and Great Plains Landscape Conservation Cooperatives of the U. S. Fish and Wildlife Service). The legend for the layer is based on NatureServe’s Ecological System Classification, with finer thematic units derived from land cover and abiotic modifiers of the System unit. Data for development...

The Yellowknife Study Area (YSA),Northwest Territories, Canada, was established in 1961 by H. W. Murdy, U.S. Fish and Wildlife Service, for the study of wetland and waterfowl ecology. The study area is located on the western edge of the Precambrian Shield and edge of the taiga and is recognized for its high wetland densities and waterfowl abundance. The region is underlain by discontinuous, warm permafrost and hence vulnerable to a warming climate. The completion of Highway 3 in early 1960s provided the first access to the region for development, research, and monitoring. The YSA is a 38-square km area centered on Highway 3, extending 48 km in length. In the 1960s, it encompassed 262 natural ponds and 313 man-made...

This publication presents data collected within meadows from samples used to assess meadow plant community responses to recreational pack stock as part of a USGS Natural Resources Preservation Project. High elevation meadows are a vital ecological component of mountain systems throughout western North America. They provide critical habitat for wildlife, supply key ecosystem services, and are favored destinations for people visiting the mountains. The biophysical characteristics of meadows are highly variable, especially related to hydrologic regimes and associated plant community types. In the semi-arid landscape of the Sierra, water availability operates at multiple scales strongly influencing meadow plant community...
By influencing nutrient mineralization in the soil, decomposers may affect the performance of plants and their associated herbivores. The strength of above–belowground linkages may therefore depend on the availability of nutrients in ecosystems. We investigated the dependency of decomposer- and leaf-herbivore-mediated changes in plant performance on soil nutrient availability in microcosm systems. In separate treatments, Poa annua was used as host plant for the herbivore and was grown in combination with different herb species: Plantago lanceolata, Trifolium repens, and Sanguisorba minor. At three different levels of nutrient availability, the impact of Collembola (Folsomia candida) and aphids (Rhopalosiphum padi),...

These data were compiled to assess potential changes in the climatic suitability for 66 species (dominant and associate plant species) and forecast climate exposure for 29 major plant communities within major plant communities in the southwestern United States. An objective of our study was that species within plant communities have unique climate suitability signatures and forecast changes in climatic suitability will not be uniform within the species respective communities or among species within the community. The climate suitability spatial models were developed under a modern baseline (1960-90) and future climate scenario (2041-2060) using Maxent and WorldClim temperature and precipitation variables.

Plant and soil data were collected in experimental plots in two sites ("Terrace" and "Hilltop") at Wind Cave National Park, South Dakota, and one site ("BSV") at Badlands National Park, South Dakota. At each site, 70, 2.5 x 2.5 m plots were assigned randomly to nitrogen-alone or nitrogen+water addition treatments (or no treatment for the control). Treatments were applied and data collected 2010-2013. The dataset includes six tables: (1) experimental treatments by plot and year; (2) plant and soil metrics analyzed in the larger work; (3) plant tissue and soil total carbon and nitrogen raw data; (4) plant biomass raw data; (5) canopy and ground cover raw data; and (6) canopy and ground cover codes.

This layer depicts the status, or degree of disturbance, to plant communities on the main Hawaiian Islands. Several layers were uset to create this version (v 3.4). The original HabQual layer was developed by Jon Price and Jim Jacobi based on the mapped land cover units from the Hawaii GAP analysis program (Gon et al. 2006). This map was revised by combining data on land use and the “Bare” category from the NOAA C-CAP 2005 map (NOAA National Ocean Service Coastal Services Center 2012), and adding road corridors to the heavily disturbed category based on the Tiger Roads layer (United States Census Bureau 2014). Additionally, corrections were made to this version of the map by visually inspecting previously mapped...
If plants cannot simultaneously acclimate to shade and drought because of physiological trade-offs, then plants are expected to be less tolerant to shading under drier conditions. One observation that, at first sight, seems incompatible with this idea is the fact that the establishment of new plants in dry areas is often restricted to shady sites under the canopy of other plants, called “nurse plants.� We use a graphical model to resolve this paradox. The model visualizes how facilitative patterns can be understood from the simultaneous effects of plant canopies on microsite light and moisture, and the growth responses of establishing seedlings to those factors. The approach emphasizes the fact that positive...

This data represents a vegetation map for Gauley River National Recreation Area. It contains nonoverlapping polygons which represent vegetation classes, aquatic features, and cultural features. Vegetation types were classified based on statistical analysis of plot data collected on the ground from 1995 through 2009. Polygons were delineated based on interpretation of digital and hard copy aerial photography flown in 2003. This data set was created by clipping the GARIvegetation feature class by the boundary of Gauley River National Recreation Area. Multipart polygons created by the clip operation were converted to single part polygons. Hectares and acres were calculated for each polygon using XTools.

In 1976-1981, the U.S. Fish and Wildlife Service conducted systematic surveys of forest birds and plant communities on all of the main Hawaiian Islands as part of the Hawaii Forest Bird Surveys (HFBS; Scott, J.M., S. Mountainspring, F.L. Ramsey, and C.B. Kepler. 1986. Forest bird communities of the Hawaiian Islands: their dynamics, ecology, and conservation. Studies in Avian Biology 9:1-431. See also: http://scholarspace.manoa.hawaii.edu/bitstream/handle/10125/4192/068.pdf?sequence=1). Results of this monumental effort have guided conservation efforts and provided the basis for many plant and bird recovery plans and land acquisition decisions in Hawaii during the past two decades. Data approved for public release,...

Plant cover data were collected on 16, 1-ha experimental blocks in C3 and Marsh Creek units of Seney National Wildlife Refuge, 2006-2010. Within each unit, we selected 4 pairs of blocks representing sedge-shrub habitat, with one of the pair assigned to spring burning (C3, May 2008) or summer burning (Marsh Creek, 2007 and 2008). This before-after-control-impact design provided for data collection two growing seasons before the burn (2006, 16 blocks; 2007, 15 blocks) and two-three growing seasons (2008, 2009, and 2010; 13 blocks) after burning; the unburned plot of each pair served as the control, and the burned plot of each pair the treatment. This table provides calculated measures of species richness, Shannon...
