This document lists the questions asked in the seventh cycle of the National Woodland Owner Survey. We sent printed versions of this survey to woodland owners in the United States between 2019-2023. There may be slight variation in questions among states.Access other versions of the National Woodland Owner Survey, including state variations, past cycles, and versions of the survey for urban, corporate, and island woodland owners.

People and ecosystems throughout the West depend on snowmelt to replenish groundwater, waterways, and soil moisture. Snow droughts occurs when snowpack is abnormally low, relative to the time of year and location. This type of drought can have significant economic and ecological effects. This fact sheet, part of the Drought in the West fact sheet series, explains the two types of snow drought, gives more details about their effects, and offers additional resources.

Northwest forests are home to many species of native insects that live in and feed on trees. These insects thin old, stressed, or sick trees and diversify forest structure. Under certain conditions, forest insects can also cause significant tree mortality when their populations expand in an outbreak. This fact sheet summarizes the conditions that effect insect outbreaks, highlights two prominent species, and presents some general considerations for managing insect outbreaks.This sheet was produced as a partnership between the Western Wildland Environmental Threat Assessment Center and the USDA...

The Forest Service has three primary mechanisms for gathering data about forest conditions and health at the landscape scale: Aerial detection surveys, the plot-based inventories, and satellite remote sensing analysis. This fact sheet summarizes these three data sources, and introduces an ongoing project to integrate multiple data sources in order to take advantage of their unique strengths.

As part of the Collaborative Forest Landscape Restoration Program, the Forest Service and its partners are using silviculture and prescribed fire to restore historical forest structure and composition in the northern Blue Mountains of Oregon and Washington within the Wallowa-Whitman and Umatilla National Forests. To monitor restoration effects, this project combines noninvasive methods (trail cameras and audio recording units) with traditional wildlife sampling techniques (nest checks and telemetry) to measure wildlife responses to forest restoration treatments. These data provide landscape-sc...

These tutorials are provided to teach the basics of using FOFEM, including creating reports, summaries and graphs, and interpreting results.

The Oregon Postfire Research and Monitoring Collaborative is an interagency group that facilitates shared stewardship by increasing awareness of efforts by various natural resources agencies and organizations to assess and learn from wildfires. It formed in response to the September 2020 Labor Day fires that burned 1.2 million acres in Oregon.Our members span Federal, State, Tribal, and local governments, universities, and the private sector. The collaborative’s structure includes a leadership team and a science team.
