“…To fill the need for more detailed information on regeneration, the Northern Research Station's FIA program (NRS-FIA) added protocols to collect regeneration data on a subset of sample plots (Phase 2-plus plots) during the growing season (McWilliams et al 2015). The results in this report are based on measurements of 184 plots measured from 2012 to 2014.…”

This report summarizes the third annual inventory of Wisconsin's forests, conducted 2009-2014. Wisconsin's forests cover 17.1 million acres with 16.6 million acres classified as timberland. Forests are bountiful in the north with Florence, Forest, Menominee, and Vilas Counties having over 90 percent forest cover. In the southeastern part of the State, forest cover is lowest with Dodge, Fond du Lac, Milwaukee, and Racine Counties having less than 10 percent forest cover. The sawtimber volume on timberland has been rising and is estimated to be 69.5 billion board feet. Oak/hickory is the predominant forest-type group, covering one-quarter of the forest land. The statewide growth-to-removal ratio on timberland is 2.2, indicating growth is outpacing removals. Additional information on Wisconsin's forests such as growth, mortality, species composition, ownership, diseases, invasive plant species, and forest economics is detailed in this report. Information on forest inventory methods, data quality estimates, and important resource statistics can be found online at https://doi

The U.S. Forest Service Forest Inventory and Analysis (FIA) program collects sample plot data on all forest ownerships across the United States. FIA's primary objective is to determine the extent, condition, volume, growth, and use of trees on the Nation's forest land through a comprehensive inventory and analysis of the Nation's forest resources. The FIA program strives for transparency by making the methods and results of the inventory and analysis available to the public. The standard for distributing FIA data is the FIADatabase (FIADB). FIADB data for individual states can be downloaded from the FIA DataMart at https://www. fia.fs.fed.us/tools-data/ as Microsoft Access© databases, which can be used to generate estimates of forest area, number of trees, volume, biomass, growth, removals, and mortality. This report complements the Northern Research Station's FIA 5-year state reports beginning with the 2014 inventory and includes detailed information on forest inventory methods, important resource statistics, quality of estimates, and key references.

“…To address the need for more detailed information on regeneration, the FIA program added regeneration measurement protocols for collecting data on a subset of NRS-FIA sample plots (McWilliams et al 2015). The results presented here for Delaware reflect only two of the seven panels of measurements that will eventually make up the first full baseline dataset for the regeneration indicator and include only seven sample plots visited in 2012 and 2013.…”

This report summarizes the 2013 results of the annualized inventory of Delaware's forests conducted by the U.S. Forest Service, Forest Inventory and Analysis program. Results are based on data collected from 389 plots located across the State. There are an estimated 362,000 acres of forest land in Delaware with a total live-tree volume of 936 million cubic feet. There has been no change in the area of forest land since 2008, however, live-tree volume in Delaware has been increasing. Forest land is dominated by the oak/hickory forest-type group, which occupies 53 percent of total forest land area. Seventy-four percent of the forest land area is in large diameter stands, 12 percent in medium diameter stands, and 13 percent in small diameter stands. The volume of growing stock on timberland has been rising since the 1950s and currently totals 811 million cubic feet. Between 2008 and 2013, the average annual net growth of growing-stock trees on timberland was approximately 16 million cubic feet per year. Additional information is presented on forest attributes, ownership, carbon, timber products, species composition, regeneration, and forest health. Detailed information on forest inventory methods, data quality estimates, and summary tables of population estimates are available online at https://doi
