The images in our galleries reflect the history, place, people, and research of the HJ Andrews Experimental Forest and Long-Term Ecological Research site. Images may be downloaded for use in papers, posters, presentations, etc. We ask that both the photographer and the HJ Andrews Experimental Forest research program, funded by the National Science Foundation's Long-Term Ecological Research Program, US Forest Service Pacific Northwest Research Station, and Oregon State University be acknowledged and cited whenever an image is used. Please refer to the data use policy and suggested acknowledgements. In some cases, higher resolution images may be available from the database manager.
