Abstract
The biomass raster was developed by equations in (Seidl, et al 2012). Lidar variables used to create the raster include 95th percentile height, bare earth elevation, and the standard deviation of height in a 35m moving window. Watershed Sciences, Inc. (WS) collected Light Detection and Ranging (LiDAR) data from HJ Andrews and the Willamette National Forest (NF) on August 10th and 11th 2008. Total area for this AOI is 17,705 acres. The total area of delivered LiDAR including 100 m buffer is 19,493 acres.

Purpose
- Live biomass is a forest metric derived from Lidar point clouds. This metric provides maps and images of aboveground live biomass for the HJ Andrews Experimental Forest. Live biomass can give a sense of how much vegetation exists on the landscape.

Abstract
- The H.J. Andrews Experimental Forest is a living laboratory that provides unparalleled opportunities for the study of forest and stream ecosystems in the central Cascade Range of Oregon. Since 1980, as a part of the National Science Foundation Long Term Ecological Research (NSF-LTER) program, the Andrews Experimental Forest has become a leader in the analysis of forest and stream ecosystem dynamics.
- Long-term field experiments and measurement programs have focused on climate dynamics, streamflow, water quality, and vegetation succession. Currently researchers are working to develop concepts and tools needed to predict effects of natural disturbance, land use, and climate change on ecosystem structure, function, and species composition.
- The Andrews Experimental Forest is administered cooperatively by the USDA Forest Service Pacific Northwest Research Station, Oregon State University and the Willamette National Forest. Funding for the research program comes from the National Science Foundation (NSF), US Forest Service Pacific Northwest Research Station, Oregon State University, and other sources.

Study Area Description
-
Long-Term Ecological Research The Andrews Forest is situated in the western Cascade Range of Oregon, and covers the entire 15,800-acre (6400-ha) drainage basin of Lookout Creek. Elevation ranges from 1350 to 5340 feet (410 to 1630 m). Broadly representative of the rugged mountainous landscape of the Pacific Northwest, the Andrews Forest contains excellent examples of the region's conifer forests and associated wildlife and stream ecosystems. These forests are among the tallest and most productive in the world, with tree heights of often greater than 250 ft (75 m). Streams are steep, cold and clean, providing habitat for numerous aquatic organisms.

The model assumes a linear combination of parameters with the cube root of aboveground live biomass (Mg) at 25 m2 cells as response variable. Aboveground live carbon was derived by assuming a C content of 50%. 2. Derived from 100,000 iterations of a nonparametric boostrap in which groups of spatially dependent observations were resampled with replacement. 3. 95th percentile Lidar return height. 4. Variance in H95 across a 35 m 9 35 m area centered on the focal 5 m cell.
