Throughout much of eastern North America, quantitative records of historical fire regimes and interactions with humans are absent. Annual resolution fire scar histories provide data on fire frequency, extent, and severity, but also can be used to understand fire-climate-human interactions. This study used tree-ring dated fire scars from red pines (Pinus resinosa) at four sites in the Northern Sands Ecological Landscapes of Wisconsin to quantify the interactions among fire occurrence and seasonality, drought, and humans. New methods for assessing the influence of human ignitions on fire...

This resource update provides an overview of forest resources in Alabama based on an inventory conducted by the U.S. Forest Service, Forest Inventory and Analysis (FIA) program at the Southern Research Station in cooperation with the Alabama Forestry Commission. Estimates are based on field data collected using the FIA annualized sample design and are updated yearly. The estimates presented in this update are for the measurement year 2015 and are compared to data reported in 2014. The sample plot population in Alabama consists of 5,658 plots, collected across a period of about 8 years...

The annual inventory of West Virginia's forests, completed in 2013, covers nearly 12.2 million acres of forest land with an average volume of more than 2,300 cubic feet per acre. This report is based data collected from 2,808 plots located across the State. Forest land is dominated by the oak/hickory forest-type group, which occupies 74 percent of total forest land area. Seventy-eight percent of forest land area consists of a plurality of large diameter trees, 15 percent contains medium diameter trees, and 7 percent contains small diameter trees. The volume of growing stock on timberland...

Dalmatian toadflax, Linaria dalmatica (L.) Mill., and yellow toadflax, Linaria vulgaris Mill., are exotic weeds of rangeland, grassland, forests, and cropland. Both Dalmatian and yellow toadflax are short-lived perennial forbs that are easily recognized by their yellow snapdragon- like flowers (Figure 1a, 1b). Both species propagate by seed and vegetatively from shoots that arise either from lateral rhizomes (Dalmatian toadflax) or from buds developing on their roots (yellow toadflax). Dalmatian toadflax is native to southeastern Europe while yellow toadflax is considered to be native to...

The U.S. Forest Service, Forest Inventory and Analysis program conducts the National Woodland Owner Survey in order to better understand: who owns America's forests, why they own it, what they have done with it in the past, and what they intend to do with it in the future. This document summarizes data on family forest ownerships with 10+ acres in Minnesota. These summaries are based on responses from randomly selected landowners from across Minnesota collected between 2011 and 2013 (n=351). For explanations of the numbers and figures below, underlying summary tables, additional results,...
