Biodiversity - Fauna - Soil Fauna - Relative frequency of terrestrial isopod species in urban and rural forests
Relative frequency of terrestrial isopod species in urban and rural forests Introduction The Baltimore Ecosystem Study (BES) has established a network of long-term permanent forest plots. These plots will provide long-term data on vegetation, soil and hydrologic processes in the key ecosystem types within the urban ecosystem. The current network of study plots includes eight forest plots, chosen to represent the range of forest conditions in the area. The goal of the soil invertebrate survey was to compare community composition and abundance of soil macrofauna, primarily earthworms (Oligochatea), terrestrial isopods (Isopoda: Oniscidea), and millipedes (Diplopoda). Plot Locations and Characterizations In November of 1998 four rural, forested plots were established at Oregon Ridge Park in Baltimore County northeast of the Gwynns Falls Watershed. Oregon Ridge Park contains Pond Branch, the forested reference watershed for BES. Two of these four plots are located on the top of a slope; the other two are located midway up the slope. Four urban, forested plots were established in November 1998, two at Leakin Park and two adjacent to Hillsdale Park in west Baltimore City in the Gwynns Falls. One of the plots in Hillsdale Park was abandoned in 2004 due to continued vandalism. Plot locations: Hillsdale 1: 39�19'28.14"N, 76�42'16.49"W Hillsdale 2: 39�19'31.24"N, 76�42'28.62"W Leakin 1: 39�18'1.32"N, 76�41'37.08"W Leakin 2: 39�18'5.42"N, 76�41'34.15"W Oregon top-slope - 1: 39�28'51.11"N, 76�41'22.50"W Oregon mid-slope - 1: 39�28'51.32"N, 76�41'18.24"W Oregon top-slope - 2: 39�29'12.74"N, 76�41'22.88"W Oregon mid-slope - 2: 39�29'12.68"N, 76�41'18.62"W Soil arthropods were sampled between November 1999 and 2000 using pitfall traps. At each plot a total of ten traps were placed which were emptied monthly. Earthworms were sampled using a combination of formalin solution (Raw 1954) and mustard suspension. 50cm x 50cm quadrats were used. Earthworms samples were taken is spring, su
Terrestrial Gradient Throughfall Collections
To investigate long-term forest ecosystem responses to disturbance and stress along an elevational gradient, five plots were established as follows: xeric oak-pine at 782 m, cove hardwood at 795 m, low elevation mixed oak at 865 m, high elevation mixed oak at 1001 m, and northern hardwoods at 1347 m. Phenomena being studied in these plots include: climatology, nutrient dynamics, decomposition, vegetation productivity and population dynamics, and below-ground processes. As part of study on nutrient dynamics, throughfall was sampled weekly and concentrations and fluxes were examined from each of the five gradient plots.
Maximum soil depth measurements from the Terrestrial Gradient plots at the Coweeta Hydrologic Lab in Macon County, NC.
Maximum soil depths were assessed as part of the soil chemistry studies at the gradient plots at the Coweeta Hydrologic Laboratory in Macon County, North Carolina. There were 5 sites representing an elevational gradient and different forest types. A soil probe was used to estimate the maximum soil depth of each of the 80 x 80 -m plots at each site.
Weather and Terrestrial Microclimate Measurements from sites located at Mars Hill University
This project contains data collected from sites located on the campus of Mars Hill University in Mars Hill, NC. Weather data includes measurements of air temperature, relative humidity, wind speed and direction, precipitation, and photosynthetically active solar radiation. Soil moisture, soil temperature, and air temperature data were measured at two forested locations. At each forested location, eight soil moisture sensors were installed in transects radiating NE, NW, SE, and SW from the datalogger. Sensors were installed approximately 20m and 40m along the transect. Measurements were taken every minute and hourly and daily data values recorded.
