Soil moisture: BioCON : Biodiversity, Elevated CO2, and N Enrichment

BioCON (Biodiversity, CO2, and Nitrogen) is an ecological experiment started in 1997 at the University of Minnesota's Cedar Creek Ecosystem Science Reserve. BioCON's goal is to explore the ways in which plant communities will respond to three environmental changes that are known to be occurring on a global scale: increasing nitrogen deposition, increasing atmospheric CO2, and decreasing biodiversity. Why Biodiversity, CO2, and Nitrogen? While there are many uncertainties in global change biology, there are also some well documented facts. Some of these are: 1. The amount of carbon dioxide (CO2) in the atmosphere is rising. Since the industrial revolution, the CO2 concentration in the atmosphere has increased from approximately 275 parts per million (ppm) to about 378 ppm today. This has been largely the result of fossil fuel burning. It is expected that CO2 levels will continue to rise, and that by the year 2050 these levels will be approximately 550 ppm. CO2 is the raw material for photosynthesis and is known to affect plant growth and development. 2. The amount of nitrogen moving through terrestrial ecosystems has increased in the recent past. While natural "background" levels of nitrogen fixation have remained constant, human additions to the system through fertilizer production and fossil fuel use have increased dramatically. Nitrogen is a key nutrient for plant growth and plays a critical role in plant community structure and composition in many environments. 3. Biodiversity levels are falling. While the research and data are not as complete as they are for CO2 and nitrogen, data indicate that the number of species globally, is being reduced. Perhaps more important for ecosystem function, diversity levels on local to regional scales have fallen due to land use change, biotic invasion and many other drivers. While much is known about how each of these factors affects ecosystem functioning, many questions remain. There is also little data on how these issues affe

Continuously measured forest soil moisture at four sites in the Coweeta Basin

Volumetric soil water content was measured at four locations in the Coweeta Basin across a range of elevations. At each location, soil water content was measured from 0 to 30 cm and from 30 to 60 cm. In addition, air temperature was measured at 100 cm height and soil temperature was measured at 5 and 20 cm depth. At two locations photosynthetic available radiation (PAR) was measured below and above canopy. Measurements are recorded every 60 seconds and data output hourly.

Percent soil moisture on southern pine beetle and non-southern pine beetle impacted permanent plots in Coweeta white pine watershed 1 from 2002 to 2003

Soil moisture was compared between beetle-impacted and non-beetle-impacted white pine plots in watershed 1.

Manual soil moisture measurements from ten artificial forest gaps at the Coweeta Hydrologic Laboratory, North Carolina, 2000-2018

Ten artificial forest gaps were created in March 2002 at Coweeta, following two years of pretreatment data collection. Experimental gaps were created by pulling canopy trees with a winch until they were down. Trees, saplings, and seedlings were censused and tracked as part of a demography study. Soil moisture data was collected during the growing season as an explanatory variable for tree survivorship and mortality.

Spring and Fall Leaf Phenology from Coweeta LTER Soil Moisture Sites SM2 & SM4, Coweeta Hydrologic Laboratory, Otto, NC, 2003-2015

Spring vegetative bud break, leaf elongation, fall leaf color, and leaf senescence are monitored at the two scaffold towers located at Project 1040 soil moisture microclimate sites 2 and 4. We have identified a variety of species at the elevation extremes within the Coweeta basin for this yearly monitoring project.

Riparian Study: Soil Moisture (TDR) from the Coweeta Hydrologic Laboratory from 1993 through 1995

TDR sites are located at intervals along the hillslope beginning 0-5 m from stream edge and continuing up the slope to the ridgetop near the edge of the white pines of WS 1. Originally, seventeen plots at two depths with three replicates each were installed. After the September 1995 collection, Hurricane Opal irreparably damaged three of the control plots. Fourteen plots remain and are measured on a biweekly basis.

Riparian zone seedling establishment, growth, dynamics, and the influence of Rhododendron maximum soil moisture: forest floor data at the Coweeta Hydrologic Laboratory from 1997 to 2000

The effect of Rhododendron maximum, a dominate species in the riparian zones of the Southern Appalachians, on carbon, water, and nutrients en route to the streams is an ongoing study in the LTER research program at Coweeta Hydrologic Laboratory. To study seedling establishment, growth, and dynamics in riparian zones one m2 quadrats have been established. There are four sites which include one treatment site, where the rhododendron has been removed from the riparian zone, one hurricane site, where there is extensive disturbance from Hurricane Opal, and two control sites, one upslope from the treatment site and one upstream from the hurricane site. Each of these fours sites have ten randomly located natural regeneration one m2 quadrats as well as four randomly located replicates of three adjacent one m2 quadrats. In each of the three adjacent quadrats, the litter was removed from the lower half to determine the effect of litter on the germination and growth of seedlings. Two of the adjacent quadrats have been broadcast seeded with Acer rubrum, Liriodendron tulipifera, and Quercus rubra. In one of the two quadrats that have been broadcast seeded, a predator exclusion mesh screen, 1m x 1/2m with " openings, has been installed in the quadrat to determine the effect of small mammal predation on regeneration. Quadrats were installed on 24 April 1997 and an initial vegetation survey was conducted in May 1997. All seedlings were permanently tagged at this time and quadrat physical characteristics such as slope, aspect, and distance from stream were recorded. Broadcast seeding was done on 21 May 1997. Each year censuses will be conducted in spring and fall on each quadrat and seedling species, density, age, and annual height growth will be recorded. This project will help to document the effect of Rhododendron maximum on regeneration in the riparian areas as well as the effect of hurricane disturbance on regeneration.
