Coordinated Resource Offering Protocol (CROP)

In 2006, the U.S. Forest Service and Bureau of Land Management undertook a series of CROP pilot projects as a means of addressing the growing fuel load problem within major forest systems and the realized potential for fostering catastrophic wildfires within these systems across the United States. Focused on biomass removal (versus biomass inventory), the CROP model was initially developed in 2003 by Oregon-based Mater Engineering, Ltd. targeting unlevelized, uncoordinated, and erratic resource offerings from public forest lands at landscape scale.

The key tenets of CROP projects are to:

  1. facilitate coordination of biomass removal between public agencies;
  2. facilitate the use of long-term multi-agency stewardship contracts to achieve biomass removal;
  3. increase the certainty of "levelized" biomass supply offerings from public agencies;
  4. invite investment back into a sustainable forest management landscape; and,
  5. heighten public trust and support for biomass removal from public lands operating within a transparent process.

Completed CROPs (August 2009)

Since 2006, almost 20 CROP evaluations have been completed on over 50 million acres of public forestlands across the United States, and more CROPS are underway. The CROP evaluations were conducted in geographic regions where forest restoration and fuel load reduction efforts are a high priority. For each CROP, detailed resource offering information is provided showing the following biomass removal data for every species to be removed during a rolling five-year period:

  • Volume (by mmbf; green/dry tons; ccf ) with conversions
  • Diameter sizes: less than 4-inches, 4- to 7-inches, 7- to 9-inches, 9- to 12-inches, and greater than 12-inches
  • Species (every species evaluated for resource flow)
  • Harvest "type": fuel load reduction, timber sales, pre-commercial thinning ( PCT), or post and pole
  • Location of resource offering
  • NEPA phase for each resource offering
  • Road accessibility for each resource offering

CROP Results (New Interactive Website)

The Coordinated Resource Offering Protocol (CROP) interactive website is now available to Forest Service contractors, investors, and the general public to quickly access continually updated woody biomass supply offerings expected to be generated from public forest lands within defined landscapes over an on-going five-year period. The interactive website allows the user to quickly access supply offerings from a variety of different search options (by agency, diameter size, specie, volume, year, location, project name, NEPA phase, road conditions, or any combination of search options). CROP users are able to see quickly expected supply variations in offerings between field-level agencies (ranger districts, field offices, supervisory areas etc.). Information on live or dead supply offerings is immediately available, and the CROP Interactive Haul Distance Feature allows fast access to recalculated supply volumes, supply characteristics, and resource supplier agencies within road distance selections. Mini-CROPs based on any combination of search options within haul distances are also immediately available to the user.

Access to the CROP interactive website data is free of charge. Currently, CROP results for all of Utah and sections of Colorado, Idaho, Mississippi, Missouri, Montana, New Mexico, Oregon, South Carolina, and Washington and are all available on the CROP interactive website, as well as from the following links. Prior CROP results for sections of the New England States, Oregon, Southeast Alaska, Northern California, and Wyoming are still being transitioned to the interactive website, but are provided below in the meantime on this static website.
