What's this?

Description: The Smithsonian Conservation Biology Institute (SCBI) large forest dynamics plot is located at the Smithsonian’s National Zoo and Conservation Biology Institute in Front Royal, VA, adjacent to the northern end of Shenandoah National Park. The plot is located at the intersection of three of the major physiographic provinces of the eastern US: the Blue Ridge, Ridge and Valley, and Piedmont provinces. The forest type is typical mature secondary eastern mixed deciduous forest, with a canopy dominated by tulip poplar (Liriodendron tulipifera), oaks (Quercus spp.), and hickories (Carya spp.), and an understory composed mainly of spicebush (Lindera benzoin), paw-paw (Asimina triloba), American hornbeam (Carpinus caroliniana), and witch hazel (Hamamelis virginiana). The SCBI forest plot is 25.6 ha (640 x 400 m), including a 4-ha fenced exclosure where white-tailed deer have been excluded since 1990, as well as three 1-ha Smithsonian Monitoring and Assessment of Biodiversity Program (SI-MAB) sites, with some sites surveyed several times since 1990. In 2010 and 2011, over 500 trees were cored in order to establish a baseline of dendrochronological data and gather background on the forest plot. In 2016 the annual mortality census was amended to include coring any tree marked dead. This practice was continued in 2017 when the current chronologies were created.

Project Metadata

Taxonomic standard used: USDA Plants Database

How plots were selected: Plot was selected for inclusion into the Smithsonian ForestGEO network in 2008 and coring began in 2010.

How trees were selected: In 2010 and 2011, trees over 10cm dbh were randomly selected for coring. In 2016, 2017 (and all subsequent years) trees are cored when classified as dead in the annual mortality census.

Exclusion of trees (if any): All trees under 10cm dbh were excluded in both the random initial surveys and the annual mortality census.

How cores were collected: All cores were collected at breast height using Haglof and JIM-GEN increment borers.

How cores were processed: Cores were dried, mounted, and sanded with a belt sander or by hand when necessary to see the cell structure during periods of growth suppression.

Exclusion of cores (if any): Cores from 2010 and 2011 that were damaged beyond recognition before chronology construction in 2017 were excluded.
