Don, I don't understand your usage of the term 'salvage.' They are not doing anything to areas that have burned and are arguing that thinning existing forests target by this action will prevent fires in the future in this area. They are talking about thinning existing forest. So where does the salvage fit?

It just strikes me that if the goshawks are actively breeding and foraging in the forest as it exists, then cutting down 80% of the trees in the area they have chosen to live is not likely to make things better. Certainly the disturbance of the habitat will be a further detriment to their population. Ed "Oh, I call myself a scientist.

Where it gets more controversial is the upper story crown structure spatial arrangement and I must recommend Cole's paper/studies to you for a better understanding of forest/goshawk biological relationships.

The italicized text in maroon are my observations. The uneven aged stratum (15,233 acres) have three or more size-classes, with a little less than half in goshawk post-fledging family areas (PFA) and the remaining in foraging areas (FA). Approximately 25 percent of the stands in the project area (6,637 acres) are even-aged as a result of past shelterwood seed-tree harvests. [This means that more than half the post fledgling family areas for the goshawks is in the even-aged stands in the project area] [various tables present the projections of the forest situations 20 and 40 years in the future, however I should point out that the data used make the projections can be manipulated to produce almost any result desired] To increase tree vigor, improve tree growth and promote healthy trees, there is a need to reduce stocking to the recommended levels of about 150 trees per acre. The resulting stands would be more resilient to the effects of periodic drought, disease, insect attack, and fire. Replacement nest areas are identified within each PFA that does not have six identifiable current or historic nest areas. Within the project area there are approximately 3,200 acres of identified nest areas plus an additional 1,000 acres identified as replacement nest areas. Currently, the nesting areas average more than 600 trees per acre and some of these trees are providing ladder fuels into the overstory crowns. The average tree diameter is 6 inches and basal area is 127 square feet per acre (Table 5). The stand density index averages 295 and along with the other information means that the site is fully occupied and competition-induced mortality is occurring. Uneven-aged sites that comprise the existing nest areas display similar characteristics to the replacement nest areas. There is a need to avoid stand-replacing wildfires to maintain this wildlife habitat and move the areas toward fire-adapted conditions. The table below shows the modeling of existing nest areas over time with very high tree density levels. The existing nest sites are currently in the self-thinning mode (tree mortality) of development due to competition between trees for available light, moisture, and nutrients. By 2033 if left untreated, the trend would be continued mortality and extremely slow tree growth. The forecast for average tree diameter increases would be less than 1.0 inch in 20 years and less than 2.0 inches in 40 years. Those same trees under optimal less congested conditions should increase in diameter by 1.5 inches each decade (10 years). Tree mortality continues to increase through 2053 and puts these stands at risk from wildfire, insect attack, and disease. The probability exists that some kind of detrimental disturbance such as a wildfire could decimate these stands between now and 2053 if no corrective action takes place. [Nice ladder fire photo to add emotional impact to the data presented] [The game being played in the tables is the idea that a forest can be drastically thinned, without changing its official "Vegetation Structural Stage' as defined by the guidelines. It is in effect saying that removing 80% of the trees in the area does not affect the forest because it still is in the same classification category] this project and detailed in Chapter 2 in response to the purpose and need described on page 4: Thin and convert the even-aged stratum to uneven-aged sites in FAs (3,170 acres) and PFAs (3,467 acres) Thin uneven-aged stratum in FAs (8,026 acres) and PFAs (7,207 acres) Thin and enhance site structure in northern goshawk nest areas (3,205 acres) and replacement nest areas (1,000 acres) [This data is presented in the form of a series of tables. If you look at the numbers, consider the plan for the Uneven aged foraging areas, which contains about half of the Post Fledgling Foraging areas: 84.4% of the trees 1' to 4.9' in diameter will be removed, 49.9% of the trees 5" to 11.9" in diameter will be removed, and 9% of the trees 12' to 17.9" in diameter will be removed. Similarly in the even aged stands, which hold over half of the post fledgling foraging area, 85.9% of the 1-4.9" trees will be removed, 66% of the trees 5 to 11.9" in diameter will be removed, 54.5% of the trees 12 to 17.9" will be removed and 63.6% of the trees 18 to 23.9" will be removed. Also consider that the smaller sized trees make up a much higher percentage of the total tree population, so extremely high numbers of smaller trees will be removed. And then tell me this will not have any adverse impact on the foraging behavior of the goshawks?] [They are also proposing thinning the nesting areas of the goshawk as well, which I can not see as benefiting the goshawk population] Edward Frank "Oh, I call myself a scientist.

Much of the plan is based upon dangers they have projected that will exist in 2053. It is an amazing coincidence that their projections of the dangers involved match up so well with what they originally planned to do when the plan was first proposed in the mid- 90's without thought of these exacting numerical justifications. There is no rationale presented for doing anything to the old growth forest identified in the plan, yet it is to be thinned and harvested. In fact many areas previously identified as old growth are now classified as mature or younger forests in this latest revision. Sure looks like a hatchet job to me.
