About Us

Research has been part of the Forest Service mission since the agency's inception in 1905. Today, more than 400 Forest Service researchers work in a range of biological, physical, and social science fields to promote sustainable management of the Nation's diverse forests and rangelands, making it one of the world’s largest conservation research organizations.

This site is an online system for sharing free, full text publications by Research and Development scientists in the USDA Forest Service. Included in Treesearch are scholarly works authored by the agency’s scientists and published by journals, in conference proceedings, or in books. Treesearch also offers scholarly works published by the agency which may or may not have been authored by agency researchers.

All publications appearing in Treesearch are based on peer reviewed research to make sure they provide the best scientific information possible.

The Treesearch website has been delivering publications since January 2004, starting with a collection of just 7,000 and passing 40,000 by its tenth anniversary, with thousands added each year.

Searches in Treesearch are focused on the metadata surrounding a publication, such as author, title, publication date, subject matter, and so forth. Treesearch allows simple searches by keyword, author's last name, and publication year. For articles published by the Forest Service, searches can also specify the publishing station, specific publication series, and/or volume number.

Filters can further limit searches to publications tagged with specific topics, but not all publications have tags. Other filters are available for agency authors, the station that sponsored the publication, the type of publication, and the publication year.

The specific search fields are described below:

Keywords (All Fields): Enter the words and/or phrases to filter. Terms are searched for across title, abstract, keyword, and other text fields. Phrases should be delimited by double quotes, an example being "woody biomass". Wildcard symbols such as * or % are not supported at this time.

Last name of author: Enter the last name of the author. It can be a partial or complete spelling. Wildcard symbols such as * or % and boolean searches are not supported at this time. You can only search for one author’s last name. The Keywords field can accept more than one name and may be useful when searching for multiple authors. The filter for Author names in the results listings can be used to further isolate works by specific R&D authors.

Date Range: Select either "All Years" or a range of publication years to limit the results.

Publication Types

Publication Series: Select a publication series from the drop-down list. The list only includes the most common series names. Use the Types filter for additional choices. The Publication Series offered in the drop down are:
