Project Description

Project Title:  View help for Project Title Tree measurements from old-growth and second-growth forest stands in southeast Alaska
Summary:  View help for Summary This data publication includes three different datasets containing tree measurements from old-growth and second-growth forest stands in southeast Alaska. The measurements are compilations from four past research projects conducted by the USDA Forest Service, Pacific Northwest Research Station in Juneau, Alaska. The Cooperative Stand Density Study (CSDS) (1974-2003) and the Taylor Growth and Yield Study (Taylor plots) (1926-2003) were conducted in second-growth stands and measurements are combined into a single dataset. The Alternatives to Clearcutting study (ATC) (1995-2005) and the Juneau Hydrologic Observatory project (Juneau carbon) (2008) occurred in old-growth stands and measurements are provided as two separate datasets. Each dataset contains sample plot measurements of tree diameters and heights. In addition, the second-growth dataset includes ingrowth tree measurements, tracks tree death, tallies cut trees, and includes plot site index, stand age, and stand treatment information. Site locations are provided for all four studies as well as detailed information and graphics related to the study design and treatments.
