title: Soil Nutrient Distributions in Grassland and Shrublands of the Sevilleta NWR

description: Vegetation throughout the southwestern United States has changed from perennial grassland to woody shrubland over the past century. Previous studies on the development of 'islands of fertility' focused primarily on only the most limiting, plant-essential element, soil nitrogen (N). The research presented here addressed the question of whether other plant-essential elements, namely phosphorus (P) and potassium (K), showed similar concentration gradients under the desert shrub Larrea tridentata, creosotebush. It also examined whether the spatial distribution of N, P, and K differed from that of essential, but non-limiting nutrients, namely calcium (Ca), magnesium (Mg), and sulfur (S), and non-essential elements, namely sodium (Na), chloride (Cl), and fluoride (F). Within adjacent grassland and shrubland plots, surface soils were collected under and between vegetation and analyzed for a suite of soil nutrients. Soil nutrient distribution followed a uniform pattern that mirrored the spatial homogeneity of bunchgrasses in the grassland, but followed a patchy distribution that mirrored the spatial heterogeneity of individual shrubs in the shrubland. The main differences were that in the grassland, all elements were uniformly distributed, but in the shrubland the plant-essential elements, nitrogen, phosphorus, and potassium, were concentrated under the shrub canopy, and the non-limiting and non-essential elements were either concentrated in the intershrub spaces or were equally concentrated under shrubs and in the interspaces. Our results show how vegetation shifts from grassland to shrubland contribute to long-term, widespread change in the structure and function of desert ecosystems.

title: SBCLTER: Reef: Long Term Kelp Removal: Cover of sessile organisms, Uniform Point Contact.

description: These data describe the cover of sessile invertebrates, understory macroalgae, and bottom substrate types as determined by a uniform point contact method. The presence of over 150 taxa of sessile invertebrates and macroalgae are recorded at 80 uniformly spaced points along permanent 40m x 1m transects. Multiple species can be recorded at any given point. Percent cover of a given species on a transect can be estimated from UPC observations as the fraction of total points at which that species was present x 100. The total percent cover of all species combined using this method can exceed 100%; however, the percent cover of any single species cannot exceed 100%. These data are part of SBC LTER's Kelp Removal Experiment, which began in 2008 and was designed to track patterns in species abundance and diversity of reef-associated organisms at kelp removal and kelp control locations in the Santa Barbara Channel, California, USA. The sampling locations in this dataset include one kelp control and one kelp removal transect at each of four reef sites along the mainland coast of the Santa Barbara Channel. These sites reflect several oceanographic regimes in the channel and vary in distance from sources of terrestrial runoff. Data collection began in 2000 and this dataset is updated annually.

title: SBCLTER: Reef: Kelp Removal Experiment:: Fish Abundance

description: These data describe the abundance and size of fish species as part of SBCLTER's Kelp Removal Experiment to track long-term patterns in species abundance and diversity. This study began in 2008 in the Santa Barbara Channel, California, USA, and the dataset is updated annually. The abundance and size of all taxa of resident kelp forest fish encountered along one kelp removal and one kelp control transect are recorded at four reef sites located along the mainland coast of the Santa Barbara Channel. These sites reflect several oceanographic regimes in the channel and vary in distance from sources of terrestrial runoff. For these surveys, fish were sized and counted in a 2x2 meter water parcel along a 40m transect.

title: ACEAS VEG-TRANS ACT, Belconnen Naval Transmission Station

description: Pre-European benchmark-analogue vegetation: The original vegetation for the site was a temperate grassland is a native ecological community that is dominated by native species of perennial tussock grasses. The dominant grasses are Themeda triandra, Austrodanthonia species, Austrostipa species, Bothriochloa macra and Poa species. The upper canopy stratum generally varies in height from mid-high (0.25–0.5 metres) to tall (0.5–1.0 metres). There is also a diversity of native herbaceous plants (forbs), which may comprise up to 70% of species present. The community is naturally treeless or has less than 10% projective foliage cover of trees, shrubs and sedges in its tallest stratum. In the ACT it occurs where tree growth is limited by cold air drainage, generally below 625 metres altitude. Brief chronology of changes in land use and management: Up to late 1820s the area managed by indigenous people. 1830s area first grazed by sheep and cattle with the aid of shepherds. 1860 fences were established and continuous stocking commenced. 1900 patches of woodland areas on higher ground were partly cleared. 1900-39 high likelihood of moderate to heavy grazing pressure due to sheep and cattle. 1940-1993 area managed as a naval transmission station. 1940-92 area managed for sheep grazing under continuous grazing. 1970 high likelihood that secure people and kangaroo proof fence established. 1993 sheep removed from the site. 1995 mowers used to manage the grass. 1997-2008 kangaroo population increased to unacceptable levels. 2006 naval transmission towers demolished. Area continued to have a secure people proof fence. 2008 kangaroo population culled to reduce grazing pressure. 2011 site managed for nature conservation values.

title: 1999 Sevilleta LTER NPP Quadrat Sampling Data

description: Net primary production (NPP) is a fundamental ecological variable that measures rates of carbon consumption and fixation. Estimates of NPP are important in understanding energy flow at a community level as well as spatial and temporal responses of the community to a wide range of ecological processes. A long-term study has been established at the Sevilleta LTER to monitor net primary production across four distinct ecosystems: creosote dominant shrubland, black grama dominant grassland, juniper-savannah and pinyon-juniper woodland. While measures of both below and above ground biomass are important in estimating NPP, the described study focuses on estimating above ground biomass production (ANPP). ANPP is equal to the change in plant mass, including any losses to death and decomposition, over a given period of time. To measure this change, above ground biomass production (ANPP) is sampled three times a year (winter, spring and fall) for all species at each of the four sites. In addition, volumetric measurements are obtained from permanent plots at the three sites to build regressions correlating biomass and volume.
