GIS vector data for sample locations and plots associated with the Hillslope Study in Macon County, NC

Coweeta Long Term Ecological Research Program & Lawrence E. Band
The Hillslope Study sites represent a gradient of landscapes, including forested, valley agriculture, and mountain housing developments. These locations and plots were used to collect samples of various matrices for numerous analyses at differing intervals. The data set consists of Open Office spreadsheet and other files that document all the Hillslope Study locations.

Flashiness of urban and desert streams in semi-arid Arizona watersheds (2003-2016)

Lauren McPhillips, Rebecca Hale, Stevan Earl & Nancy Grimm
The general consensus that urbanization results in dramatic changes in stream hydrology, such as higher peak flows and greater flashiness, has not been definitively tested for aridlands, which are themselves characterized by these very same hydrograph properties. This study analyzed streamflow records from 33 watersheds of central and southern Arizona, USA to determine how hydrograph characteristics varied across a range of development. Relationships of hydrologic parameters to urbanization were not evident when all catchments were...

Perennial species canopy cover across grazed/ungrazed fencelines in the Jornada Basin, 1986-2015

Walter Whitford
This ongoing data set contains percent canopy cover estimates of perennial plant species from transects that cross a grazed/ungrazed boundary fenceline of a single exclosure on the New Mexico State University Chihuahuan Desert Rangeland Research Center in Dona Ana County, New Mexico, USA. In the spring of 1982, as part of the establishment of the Jornada Long-Term Ecological Research site in southern New Mexico, a 135 ha portion of a 1500 ha, internally drained, watershed...

Aboveground Net Primary Productivity across inter-annual precipitation variability treatments at a grassland site in the Jordada Basin, 2009-2014

Laureano Gherardi
This ongoing dataset contains annual aboveground net primary productivity (ANPP) data from a study at the Jornada Experimental Range (JER) in southern New Mexico.

End of Year Biomass for the 1st UPC Inundation Experiment in Upper Phillips Creek marsh 1999-2014

Robert Christian
The objective of this study was to determine the individual and compound effects of inundation and wrack deposition on high marsh community structure. Inundation pattern and wrack presence were manipulated individually and in combination, in two neighboring communities (a Juncus roemerianus-dominated and an adjacent Spartina patens and Distichlis spicata-dominated) in 1994 and 1995. Aboveground biomass was used to assess marsh response to the stressors of increased inundation and wrack presence (Tolley and Christian 1999) and...

Hurricane record for the Virginia Coast Reserve, 1667-1976

Bruce Hayden
Goals for project BPH8801 --> To build an inventory of tropical storms on the VCR from 1650 to present. While tropical storms are infrequent (several landfalls per 100 years) the magnitude of the disturbance is great. Storm surges 10 feet plus are expected with waves of 17 to 23 feet offshore. The record being developed will serve as a benchmark and will serve when the next tropical storm comes. Comparisons of frequency and magnitude can...

End of Year Biomass for the 2nd UPC Inundation Experiment in Upper Phillips Creek marsh 1999-2010

Robert Christian
The objective of this study is to determine the effect of increasing inundation on healthy (in-tack turf) and unhealthy (hollow and hummock topography) high marsh habitat. Brinson et al. (1995) developed a model representing the change that occurs in ecosystem state (or habitat type) along the shorezone, from the forest -> high marsh -> low marsh -> mud flat, in response to the increased inundation caused by rising sea-level. They suggested that a seaward shift...

Cone production of upper slope conifers in the Cascade Range of Oregon and Washington, 1959 to present

Andrews Forest LTER Site & Jerry F. Franklin
Seed supply is a key feature of tree population dynamics, and seed production may be indicative of environmental and biological drivers. This study examines cone production in upper-slope, true fir-hemlock forests of the Pacific Northwest, starting in 1959 to the present. Annual surveys of cone counts of Abies spp. (A. amabilis, A. concolor, A. grandis, A. lasiocarpa, A. magnifica, A. procera), Pinus spp. (P. engelmannii, P. lamberti, P. monticola), and Tsuga spp. (T mertsiana) have...
