Progress to Date

  • 256 field model plots completed in 2000
  • Acquisition of imagery 80% complete
Results as of December 2002

Field training, data collection and accuracy assessment data collection have been completed.

A total of 233 vegetation sampling plots were established in the northern Sierra Nevada and 285 plots were established in the southern Sierra Nevada.

Analysis was conducted on collected crown dimension data (height to partial crown and height to full crown) to determine crown bulk density (CBD) and height to live crown (HLC) measurements for identified vegetation types (Figures1-4). We utilized the Reinhardt algorithm for computing crown bulk density and height to live crown.

Lidar Results

Currently, the remote sensing portion of the project is underway by the University of Maryland (Dubaya, Hyde and Peterson). Analysis is being conducted to compare the results of the field-collected measurements versus the remotely sensed forest structure predictions. Remotely sensed LVIS data has been processed and has been successfully used to map canopy height, total biomass, and canopy cover. Analysis of crown bulk density and height to live crown are currently underway and preliminary results are expected to be presented at the March JFS Principal Investigator Workshop.

Radar and Fusion Results

These portions of the project are currently in progress.
