Analysis of Small Diameter Wood Supply in Northern Arizona

 

The key findings of the original sustainability analysis published by AZFRP in 2006 have been confirmed by the findings of the collaborative Analysis of Small Diameter Wood Supply in Northern Arizona published by Northern Arizona University ForestERA group in February 2008.

 

The collaborative Analysis of Small Diameter Wood Supply in Northern Arizona can be downloaded from the ForestERA website at http://www.forestera.nau.edu/project_woodsupply_finalreport.htm or from the AZFRP website here.

 

 

Key findings of the two analyses

 

The key findings of the 2008 NAU ForestERA Analysis of Small Diameter Wood Supply in Northern Arizona compare with the key findings of the 2006 AZFRP sustainability analysis as follows:

 

 

2008 NAU ForestERA Analysis of Small Diameter Wood Supply in Northern Arizona

  "Consensus Scenario"

 2006 AZFRP Sustainability Analysis
Existing backlog to be thinned by acre

8.5 ccf/acre

(Table 11 p. 58)

8 ccf/acre

(Step #1)
Net annual forest growth estimate over next 20 years

34 ft3 / acre

(Table 20 p. 64)

35 ft3 / acre

(Step #3)
Acreage of national and state forests requiring mechanical thinning

987,206 acres

(Table 11 p. 58)

985,500 acres

(Step #2: National + State Forests)
Available wood supply backlog in national and state forests requiring mechanical thinning

847 million ft3

(Table 11 p. 58)

788 million ft3

(Step #2: National + State Forests)

 

Cleary the key findings of the collaborative Analysis of Small Diameter Wood Supply in Northern Arizona confirms the key findings of the original sustainability analysis published by AZFRP and validate the scientific basis of AZFRP's  sustainability analysis.

 

 

Critical difference between the two analysis

 

There is one critical difference between the two studies however.

 

Specifically, the collaborative Analysis of Small Diameter Wood Supply in Northern Arizona published by Northern Arizona University ForestERA group in February 2008 does NOT include the 817,000 acres of ponderosa pine forest located in the White Mountain Apache Reservation and in the Navajo Reservation.

 

Although there is a clear rational for a study funded by the Forest Service to consider only national forests, a economic wood supply analysis in Northern Arizona MUST include the tribal forests, especially in view of the fact that the tribal forests have provided as much is not more wood to the industry over the last two decades than the national forest have in Northern Arizona.

 

Considering that both the Navajo and the White Mountain Apache reservations' Department of Forestry are actively involved in forest ecosystem restoration, and that both have expressed their interest in entering a long term wood supply contract with AZFRP, the AZFRP Sustainability Analysis will continue to include the conservative assumption that  50% of the 817,000 acres of tribal forests need thinning, because this represents an economic reality.

 

Therefore:

 

 

2008 NAU ForestERA Analysis of Small Diameter Wood Supply in Northern Arizona

  "Consensus Scenario"

 2006 AZFRP Sustainability Analysis
Existing backlog to be thinned by acre

8.5 ccf/acre

(Table 11 p. 58)

8 ccf/acre

(Step #1)
Net annual forest growth estimate over next 20 years

34 ft3 / acre

(Table 20 p. 64)

35 ft3 / acre

(Step #3)
Acreage of national forests requiring mechanical thinning

987,206 acres

(Table 11 p. 58)

985,500 acres

(Step #2: National + State Forests)
Available wood supply backlog in national forests requiring mechanical thinning

847 million ft3

(Table 11 p. 58)

788 million ft3

(Step #2: National + State Forests)
Acreage of northern Arizona tribal forests requiring mechanical thinning  

408,500 acres

(Step #2: Tribal Forests)
Available wood supply backlog in northern Arizona tribal forests requiring mechanical thinning  

326 million ft3

(Step #2: Tribal Forests)
Total acreage of northern Arizona public and tribal forests requiring mechanical thinning  

1.4 million acres

(Step #2)
Available wood supply backlog in northern Arizona public and tribal forests requiring mechanical thinning  

1.1 billion ft3

(Step #4)

 

When added to the findings of the collaborative Analysis of Small Diameter Wood Supply in Northern Arizona, the wood supply backlog from the northern Arizona tribal forests confirm AZFRP’s 2006 Sustainability Study and further documents the ecological sustainability of the AZFRP project.
