Eastern White Pine Versatility in the Presettlement Forest

Multiple scale composition and spatial distribution patterns of the north-eastern Minnesota presettlement forest

1 Bearing tree data were used to characterize the composition and spatial structure of the southern boreal presettlement forest in north-eastern Minnesota, United States of America. Data collected during the General Land Office Survey (GLO) between 1853 and 1917, represents 35 324 samples (each with 1–4 trees) in a 3.2 million-hectare landscape. Nine tree species contributed at least 1% to the ...

Characterization of microsatellite markers in eastern white pine.

An enrichment cloning method was evaluated for the isolation of microsatellite loci from eastern white pine and the resulting markers were examined for polymorphisms. A 200-fold enrichment was achieved for highly abundant (AC)n repeats, but for much less abundant (ACAG)n repeats an enrichment of only 20-fold was obtained. Using a single set of PCR conditions, 19 microsatellite loci were identif...

Growth of Eastern White Pine (Pinus strobus L.) Related to Forest Floor Consumption by Prescribed Fire in the Southern Appalachians

Chainsaw fe l l ing , burning, and p lant ing of eastern whi te pine (Pinus s t robus L.) have been prescribed on degradedpinelhardwoodstands in the Southern Appalachians to improve overstory composi t ion and product iv i ty . The desired future condi t ion the overstory is a product ive pinelhardwood mixture, wi th white pine, which is resistant to southern pine beetle (Dendroctonus frontalis...

Classi ® cation and boundary vagueness in mapping presettlement forest types

Presettlement forest types were mapped as fuzzy sets from point data representing trees contained in General Land O ce survey notes (circa 1850) for Chippewa County, Michigan. The resulting representation agreed with a polygon map of the same forest types at 66% of the locations (represented as grid cells) in the county. Boundary vagueness was de® ned in relation to the slope of a linear funct...
