Methods

The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures

Current Methods


  • Started: 2001-07-01

    Carabid, Collembola and soil sampling are within the planned silvicultural treatment units: seven, 2 ha. treatment units (six manipulations and a control) with a minimum of 50 meters between each unit.

  • Treatment plans
    Started: 2001-07-01

    The planned treatments include three commercial harvests: single-tree selection, shelterwood, and crop tree release; and three new techniques designed to enhance structural complexity of forests in escalating intensities. The treatements are planned for the winter of 2002-2003.

  • Sample collection and processing
    Started: 2001-07-01

    Nested within each unit are 4 sampling plots for both Carabid and Collembola sampling. Carabid sampling is conducted using pitfall traps, collected every 2 weeks through mid-October. Specimens are pinned, sorted and identified to species. Collembola sampling is conducted usiing soil cores taken monthly through mid-October. The insects are extracted from the soil using Berlese funnels. Specimens are preserved in ETOH for later identification to family and genus level.

  • Soil sample collection and analysis
    Started: 2001-07-01

    Soil samples collected in late summer will be analyzed by horizon for organic matter content, total organic nitrogen, ammonium, nitrate, phosphorus, potassium, calcium, and other micronutrients.
