What's this?

Description: We used tree-ring data from 37 plots, randomly located within the TNC’s Big Reed Forest Reserve, to reconstruct the history of natural disturbances in this old-growth landscape.

Project Metadata

Taxonomic standard used: Other

How plots were selected: Thirty-seven plots (30 × 50 m) were established throughout the Reserve in a stratified (by forest type) random manner. Randomization was achieved by placing a 100 × 100 m grid over a base map showing forest types (Widoff 1985), and randomly selecting ordinate and abscissa grid lines, their intersection denoting a proposed plot’s southwest corner. Plot locations were rejected if they fell within 150 m of a previously selected location, the Reserve border, or a mapped boundary between forest types. Twenty-one plots were established in the mixed woods type; five in the cedar seepage forest, four each in the red spruce forest and hardwood forests and three in the cedar swamps

How trees were selected: On each plot we measured diameters and extracted increment cores (in 2000 and 2001) from all living trees of 10 cm d.b.h. (1.37 m).

Exclusion of trees (if any): None.

How cores were collected: One core was extracted per sample tree at breast height

How cores were processed: Increment cores were dried, mounted and sanded to a fine polish using standard methods.

Exclusion of cores (if any): The ring-width files (Tucson format) include only those samples that crossdated reasonably well.
