HJ Andrews Experimental Forest Map
The most current version of the Andrews Experimental Forest map is from 2011. It is formatted to be a brochure on one side, and a map on the other. It is pre-folded for ease of use. The map was produced using ESRI ArcMap software, and while hard copies were printed, this map will be updated as data changes, and posted on this site. Hard copies of the map are available in the Corvallis Forestry Sciences Lab and at the HJ Andrews Experimental Forest Headquarters.
The data sources are from the US Forest Service Research Station and the Willamette National Forest. The base topography on this map is from the 2008 LiDAR survey of the Andrews. New road and stream layers were also created from the LiDAR data. The road numbers and status were checked in the field by Andrews staff, and the climate stations and stream gages have been located by high precision GPS.

Interactive maps are built on a geospatial reference and allow users to select and deselect desired features (layers and sublayers). A legend provides identification of a particular feature. User specificed maps can be created and saved. The following interactive maps are available for the HJ Andrews Experimental Forest:
- Study Site Locations on the HJ Andrews Experimental Forest
- This interactive map was created using the 2011 HJ Andrews base map, including any subsequent changes, and allows users to select (turn on and off) various study site locations across the HJ Andrews Experimental Forest.
- Soils Data for the HJ Andrews Experimental Forest
- This interactive map was created using the Soil Survey Geographic Database (SSURGO) National Cooperative Soil Survey data collected in 2014 (referred to as new soil survey) in addition to original 1964 data and other geological and soils data for the HJ Andrews Experimental Forest.
Using the 2011 HJ Andrews Map base with ArcMap
