Vegetation Stratum Cover Data
These data were collected as part of the NSW Grazing Study. An assessment of the foliage cover of each stratum at each of the 451 sites. Each 2m along a linear transect (200m) cover of groundstorey vegetation (less than 50cm), shrubs/midstorey (50cm to 4m) and overstorey (greater than 4m) was estimated.

Plant Species Cover and Abundance Data
공공데이터포털
These data were collected as part of the NSW Grazing Study. Identification to species level of all plants, allocating an actual or estimate of cover (<1, 1, 2, 3, 4, 5, 10, 15, 20,….) and allocating an actual or estimate of abundance (0,1,2,3...10,20,30...100,200,300...). Cover and abundance estimates made in five large quadrat (5m x5m) and 5 small quadrats (0.5m x 0.5m) nested within the large quadrats. Quadrats located at the 0, 50, 100, 150, and 200m along the site transect.
Groundcover Data
공공데이터포털
These data were collected as part of the NSW Grazing Study. A range of methods employed to characterise the groundcover at each of the 451 sites. An estimate of the percentage groundcover in five (5m x 5m) quadrats into the following categories; vascular plants, bare soil, litter (including an estimate of the percentage derived from groundstorey plants), biological soil crusts (e.g. cryptogams). Enumeration of the lineal metres of coarse woody debris (diameter >10cm) in five (5m x 5m) quadrats The size and abundance of perennial grasses. In five (5m x 5m) quadrats a count of the total abundance and diameter at base of twenty grass butts.
Annual measurements of vegetation cover on line-point intercept transects from the three Conmod Pilot study locations at Jornada Basin LTER, 2008-2016
공공데이터포털
,This data package contains annual measurements of vegetation cover, species, and height from transects at the Connectivity Modifier (Conmod) Pilot study on the Jornada Experimental Range from 2008-2016. There were 3 sites for this study: Gravelly Ridges, Aeolian, and Dona Ana. Within each site, there were 8 study plots, 4 of which were treatment plots where connectivity modules (conmods) were installed to decrease gap sizes between perennial vegetation. The plots were 8 x 8 meters and had an 8 x 8 meter buffer zone on both sides of the plot (upwind and downwind). Beginning in 2008, vegetation cover by species, and vegetation heights were collected annually in all plots using the line-point intercept method. These data were collected in 2008-2010, 2012 and 2016. At each plot, four parallel 24-meter transects crossing the upwind buffer, the plot, and the downwind buffer were measured. These parallel transects were spaced at 0.8, 2.8, 4.3, and 7.2 meter intervals across the plot and buffer areas. Vegetation cover and height were read at points arranged at 25 centimeter increments along each transect. This study is complete (finished in 2016) and was the pilot study to the newer Cross Scale Interactions Study.,,
SCPN Upland Vegetation herbaceous, shrub and tree vegetation and soils 2007-2024 Data Package
공공데이터포털
This data package includes data that were between 2007 and 2024 as part of the Southern Colorado Plateau Network's long-term integrated upland monitoring protocol in 10 national park units (AZRU, BAND, CHCU, GLCA, GRCA, MEVE, PEFO, PETR, WACA, WUPA) and 17 distinct ecological sites. Cover class, percent cover (based on cover class midpoints) and nested frequency of plant species and lifeform (functional) groups, cover of soil surface features, count of seedlings by species and size class, count of saplings by species and size class and status and diameter of overstory trees, soil stability ratings, soil texture and depth. Reports and subsequent analyses can be found in Cross References.

Vegetation Structure and Recruitment Data
공공데이터포털
These data were collected as part of the NSW Grazing Study. An assessment of vegetation structure and recruitment conducted at each of the 451 sites using variable belt transects. To determine tree density all mature trees were enumerated within a 200m x 1-10m (variable width) belt transect. Mature trees were enumerated into four DBH classes (5-10cm, 10-20cm, 20-30cm, >30cm). Woody (tree and shrub) recruitment was enumerated within a 200m x 1-10m (variable width) belt transect into two classes (0.5m -1.3m and 1.3 - 3m).
ISLSCP II Continuous Fields of Vegetation Cover, 1992-1993
공공데이터포털
The objective of this study was to derive continuous fields of vegetation cover from multi-temporal Advanced Very High Resolution Radiometer (AVHRR) data using all available bands and derived Normalized Difference Vegetation Index (NDVI). The continuous fields describe sub-pixel proportions of cover for tree, herbaceous, bare ground and water cover types. For tree cover, additional fields describing leaf longevity (evergreen and deciduous) and leaf morphology (broadleaf and needleleaf) were also generated. The modeling of carbon dynamics and climate require knowing tree characteristics such as these. These products were resampled and aggregated to 0.25, 0.5 and 1.0 degree grids for the International Satellite Land Surface Climatology Project (ISLSCP) data initiative II. The data set describes the geographic distributions of three fundamental vegetation characteristics: tree, herbaceous and bare ground cover, plus a water layer. For tree cover, leaf longevity and morphology layers were produced.This data set is one of the products of the International Satellite Land-Surface Climatology Project, Initiative II (ISLSCP II) data collection which contains 50 global time series data sets for the ten-year period 1986 to 1995. Selected data sets span even longer periods. ISLSCP II is a consistent collection of data sets that were compiled from existing data sources and algorithms, and were designed to satisfy the needs of modelers and investigators of the global carbon, water and energy cycle. The data were acquired from a number of U.S. and international agencies, universities, and institutions. The global data sets were mapped at consistent spatial (1, 0.5 and 0.25 degrees) and temporal (monthly, with meteorological data at finer (e.g., 3-hour)) resolutions and reformatted into a common ASCII format. The data and documentation have undergone two peer reviews.ISLSCP is one of several projects of Global Energy and Water Cycle Experiment (GEWEX) [http://www.gewex.org/] and has the lead role in addressing land-atmosphere interactions -- process modeling, data retrieval algorithms, field experiment design and execution, and the development of global data sets.
