    • Study specimens
      • dataset_eml_methodsStartDate: 1993-05-01
      • dataset_eml_methoddescription: Twenty sugar maple trees used for foliage sampling.

    • Plot description
      • dataset_eml_methoddescription: One 75 X 50 m plot used for soil, litter, throughfall and precipitation collections.

    • Leaf samples
      • dataset_eml_methoddescription: Leaf samples collected from north and south sides of tree; from lower, middle and upper canopy. Samples of leaves were collected once in mid-July and once in mid-August to obtain a measure of the maximum nitrogen pool. Foliar nutrient concentrations are most stable in this time frame.

    • Leaf litter
      • dataset_eml_methodsStartDate: 1993-09-20
      • dataset_eml_methoddescription: Leaf litter traps collected twice weekly. One litter trap was placed under each tree, positioned so that minimal litter would fall in from surrounding trees. Leaf litter was collected throughout the leaf drop period (September 20-October 22).

    • Throughfall collection
      • dataset_eml_methoddescription: Throughfall collections consisted of two funnel collectors under each of five trees, on north and south sides of tree. Plus two collectors in an open area in close proximity to the site to collect rain as a control.

    • Leaf tissue analysis
      • dataset_eml_methoddescription: After each sampling, leaf tissue was run through a leaf area meter, assigned a thrips damage index number, oven dried at 70 degrees C to a constant weight and ground in a Wiley mill.
