Nevada's Soft Shell Pinon Pine Nuts

Bad Science Destroys The World's Greatest Food Resource!

Prior to World War II the American pinyon system produced up to 8 million pounds of edible seed yearly for which there was a strong market on the east coast as well as regionally. After WWII records commercial of harvest decline as people returning from the war were encouraged to ranch rather than other types of livelihood pursuits. We know of harvest yields through historical records kept by the pinon brokers, which are archived at Northern Arizona University. Very little scientific study has been done on pine nut reproduction. It is one of the primary indicators of system health. In order for to examine the truth of the pinyon invasion, we must consider seed production and tree life cycles.

Shortly after WW II massive land conversion projects began in the West. Between the mid 1950s and 1973 more than 3 million acres of pinyon forests were converted to grasslands, generally under the auspices of "invading pinyon" myth - a theory developed to support the creation of grasslands at tax payer expense. I have found no cumulative record of conversions, vegetative treatments or landscape alterations after 1973. The areas treated were among the best and most productive of pinyon. The trees in these areas were mature seed producers, over 100 years of age.

Dr. Elbert Little began working in the pinyon system in the mid-1930's and two of his articles from 1977 and 1993 are in the packet . Dr. Little's study plots, as well as long term other study plots did not support any theory of expansion or invasion of the pinyon. I am certain you are familiar with basic pinyon ecology including the length of time which it takes (up to 125 years) for a tree pinon to become a mature seed producer. Also, the trees require shade and moisture to establish and cannot invade grasslands. P.monophylla seeds have only a 6 month seed viability window.

There has never been any major work done on documenting seed production cycles or examining the records of the pinon traders to determine the changes in the reproductive cycle of the tree. Additionally, beginning in 1964 the decline of pinyon jay, a primary seed disburser, began to decline at a rate of 4%.

If one reviews the body of literature on the pinyon system as a whole, it fairly easy to watch the evolution of poorly developed applied science. One of my favorite examples is the scientist from Los Alamos who discovered shade as a factor in watershed soils moisture after 20 year policy of pinyon removal justified as enhancing regional moisture through freeing up ground water. Another example is included: Vegetation differences in desert shrublands of western Utah's Pine Valley between 1933 and 1989. I have also included other work done with long term study plots in the packet. None of this research supports the theory of an expansion of the pinyon system.

Additionally enclosed you will note that the reference number of pinyon system numbers in the mid 1970's is much greater than that currently used. The 1989, Analysis of Land Base Situated in the U.S. 1989, asserts about 47 million acres of pinyon-juniper. Jim Dobrowolski, cites pinyon-juniper rangelands as occupying more than 30 million acres. Additionally, airplane assessments collected on the pinyon die- off indicate tallied 1.9 million acres damaged in 2003 compared to 11.9 million acres were damaged in 2003. The 1950's drought impacted 490,000 acres in 1957. Records from the 1950's drought indicate that the pinon populations impacted were less than 100 years old and the species was not re - establishing well in the 19^th and 20^th century (Betancourt).

While popular theory was expanded biomass and competing weakening species resistance. Betancourt raised the question of water table and agriculture water use a possible contributor the pinyon die-off in the 1950's. It is my opinion that scientific community is failing to ask the right questions, because of the widely held acceptance "of pinyon invasions."

First hand accounts indicated that between 1993 and 2004 there had been no major seed harvest of P.edulis. There are no records of P. Monophylla harvests, other than auction sales records which are not reflective of actual harvests. Oral histories of Native American seed collectors would represent the best potential resource for determining changes to the reproductive patterns of the pinyon. It is very difficult for a species to invade when it is not reproducing well. This further supported by the work done on climate

The pinyon did not invade the public lands of the West, yet this was the driving theory in justification of land use treatments prior to the "fuels reduction mania" of the 1990's. The pinyon is a fire resistant species requiring 700 lbs of fine flash fuels to ignite. Everyone in the west understands the role of cheat grass in fires, yet most monies have been spent on treating pinyon - another example of range creation driving management, rather than solid scientific policy. Additionally, new pressures in the form of biomass utilization, which again has be formulate upon the mythical invading pinyon is threatening the pinyon system. Records indicate that we have only a tiny reservoir of mature seed producing pinyon trees, those in excess of 125 years of age. As a result we are weakening the genetic resources of the primary vegetative resource of the region resulting from poor science developed to support industry rather than objective, solid scientific study. We are turning this productive forest into a wasteland through our failures in recognizing the mistakes that lead to derogation of the lands in the first place.

I would like to understand the scope of change created by land use priorities. Are you aware of any survey done, which addressees pinyon acres treated from 1973 forward, including fuels reductions, chaining maintenance (it was common to double or triple the original treated areas under a maintenance plan), wild life enhancement (nuts are a major wild life food resource, yet, many plans have removed trees in order to enhance grasslands under the guise of wildlife improvement), watershed improvement, prescribed burns or other nomenclature? How could these trees be invaiding when their life-cycle indicates it is not even possible for them to have recovered from these massive deforestation projects?

Creating a cumulative record of deforestation projects is critical to any real "restoration effort" together with a problematic analysis of forest changes that incorporates the die off and the consequences of the conversions to the entire southwest. The range culture rather than forestry has control most of the policy and vision for the land. For example, The Eastern Landscape Coalition, chaired by the former executive director of the Cattlemen’s Association, Besty McFarlan and people who are invested in range are those who are invested in the "invading pinyon myth." The restoration policy is being driven by grasslands policy developed as a result of desired use, rather solid science developed to support the natural forestry values of pinyon system.

Managing these public lands in compliance with FLMPA multi use criteria requires a change of thought and a redirection in policy. Field officers cannot expend the time and manpower to monitor harvests or seed production as all forestry revenues flow away from their districts. Is there a mechanism for returning forestry revenues back to the local districts, so that some of this work can be done and the districts have an incentive to manage for forestry values?

I have worked with some outstanding, knowledgeable BLM people, whose on the ground experience, formal education and competence are unquestionable. These include Skip Ritter, Nevada State Office Forester; and Harry Rhea, Ely District former regional forester Harry Rhea 775-289-1848. These gentlemen have proven themselves to be ethical and committed foresters with great insight into the factors which are inhibiting multiple use and sustainable yield in the Great Basin Region.

In the Pinyon Juniper Woodlands, Elbert Little 1977

Walnut Canyon Pinyon plot 1937 -1977 - no show increased numbers of trees. 40 years field work no sign of pinon invading into grassland. Pinon cannot establish in grasslands, needs nurse trees and moisture. Pinons require 75 - 100 years to become seed mature producing stock. Juniper possibly expanding due to livestock transportation of seeds. Observed seed production decline by conversions of the 1950's. No research done prior to wide scale conversions of 1950 - 1970's. Post WW II management became mon-culture and pinyon ranges were converted without scientific support.

Pinyon Juniper Woodland - Denis Austin

Twenty three year study plot:

No major changes to the areas or vegetation. 14 years no change in number P.edulis found.

46 Year Study plot

No introduction of pinyon into area.

Single juniper established, which was 400 m from the range of the juniper stand.

Note: This study came to my attention in that it was cited to support pinyon invasion and I wanted to see the methods in the study. Additionally, it is this was one of our commercially harvest regions for pinyon pine nuts 2005.

Pinon eradication changed harvest dynamics and reproduction. Best sites for pinyon nuts converted (comment- better soils, converted for grasslands). Converted landscapes were trees 100 - 200 years old not invaders, unscientific work.

Failure of public land managers to manage pinyon resource.

CULTURE AND LAND USE POLICY - PLEASE REVIEW IN FULL

Notes survey done on agency management of pinyon woodland products.

Documents failure to manage and monitor the pine nut/woodland resource.

Recounts major seed production years and demonstrates through study of 1950's drought that pinon were not expanding due to poor seed establishment. Written pre- 2000 die off but suggests lowered water tables/agriculture land use may impact pinyon during drought.

Pinyon-juniper woodland, which covered approximately half of Mesa Verde National Park in 1906, is now restricted to less than 25 % of the park area. The biological reasons for failure of
pinyon and juniper to reestablish after severe fires of the past century are unknown.
