  1. Estimating the quadratic mean diameters of fine woody debris in forests of the United States

    Most fine woody debris (FWD) line-intersect sampling protocols and associated estimators require an approximation of the quadratic mean diameter (QMD) of each individual FWD size class. There is a lack of empirically derived QMDs by FWD size class and species/forest type across the U.S. The objective of this study is to evaluate a technique known as the graphical...

  2. The downed and dead wood inventory of forests in the United States

    The quantity and condition of downed dead wood (DDW) is emerging as a major factor governing forest ecosystem processes such as carbon cycling, fire behavior, and tree regeneration. Despite this, systematic inventories of DDW are sparse if not absent across major forest biomes. The Forest Inventory and Analysis program of the United States (US) Forest Service has...

  3. STEW-MAP in the New York City region: survey results of the Stewardship Mapping and Assessment Project

    The Stewardship Mapping and Assessment Project (STEW-MAP) began in 2007 as a way to understand and map civic capacity to care for the environment across New York City. In 2017, we implemented a ten-year update to STEW-MAP in New York City's five boroughs and expanded it to the larger metropolitan area as a regional pilot survey. In this report, we share our...
