Insects are essential components of forest ecosystems, representing most of the biological diversity and affecting virtually all ecological processes (Schowalter 1994).
This report assesses recent forest disturbance in the Western United States and discusses implications for sustainability. Individual chapters focus on fire, drought, insects, disease, invasive plants, and socioeconomic impacts.
This report traces the flow of California’s 2016 timber harvest through the primary wood products industry and characterizes the structure, condition, and economic impacts of California’s forest products sector.
Humans and wildlife interact in multifaceted ways on public lands with both positive and negative outcomes for each group. When managed well, wildlife-based tourism and other forms of recreation can benefit conservation goals.
Recreation and tourism on public lands benefit visitors through improved health, enjoyable experiences, and enrichment from our natural and cultural heritage.
Scientists and natural resource managers use bioindicators for overcoming the limitations of instrument-based monitoring networks. Low sampling costs make lichen bioindicators an invaluable tool for detecting finer scaled patterns in air quality than can be detected using instruments.
Burn severity is the ecological change resulting from wildland fires. It is often mapped by using prefire and postfire satellite imagery and classified as low, moderate, or high.
Of California’s almost 100 million ac, about a third are forested (32 million ac). This report, including the accompanying tables, summarizes key findings from the 5,369 Forest Inventory and Analysis (FIA) plots measured in California’s forests during the period 2006–2015.
Public lands provide opportunities and settings for people to experience nature and the outdoors. These outdoor experiences are important for human health and well-being and result in visitor spending that benefits local communities.
This report highlights key findings from the most recent 10-year survey of Forest Inventory and Analysis (FIA) data collected across southeast and south-central Alaska and represents the first full remeasurement of all forest plots in the coastal Alaska inventory unit.
