The methods followed in the creation of the dataset, including description of field, laboratory and processing steps, and quality control procedures
Past Methods (No longer in use)
- Survey and collection locations
Started: 1993-07-15
Ended: 1993-08-31Eighteen locations, about 2 acres in size each, were used for the species survey and collections for chemical analysis. Locations represented the wilderness geographically and vegetationally. Undisturbed and disturbed habitats were sampled.
- Health conditions of lichen
Started: 1993-07-15
Ended: 1993-08-31Voucher specimens were collected for all species found. General health of lichens was recorded by looking for damaged or dying lichens on all trees where collections were made (at least 100 trees).
- Lichen collection
Started: 1993-07-30
Ended: 1993-08-09Lichens were collected in spunbound olefin bags at four localities for laboratory analysis: north of Little Mud Pond, hill west of Lye Brook, west side of Bourn Pond and north of Kelly Stand Road. Species collected were: Cladinia rangiferina; Evernia mesomorpha; Hypogyminia physodes; and Parmelia sulcata. Ten to twenty grams of each species was collected at each locality.
- Chemical analysis
Started: 1993-07-30
Ended: 1993-08-09Chemical analysis measurements included: sulfur, Ca, Mg, Na, K, P, Fe, Mn, Al, Cu, Zn, Cd, Cr, Ni, Pb, and B.
