Forest Service; United States. Bureau of Land Management<br/><br/>Abstract: The Secretaries of Agriculture and the Interior propose limited changes to language withinthe Aquatic Conservation Strategy, part of the Northwest Forest Plan. Projects needed to achieveNorthwest Forest Plan goals have been delayed or stopped due to misapplication of certain passages inthe Aquatic Conservation Strategy. The Secretaries are responding to the underlying need to followNorthwest Forest Plan principles and achieve its goals. Two alternatives are considered in this DraftSupplemental Environmental Impact Statement, No Action and Proposed Action. No Action wouldnot change existing language within the Aquatic Conservation Strategy. The Proposed Action wouldmake limited changes to clarify how the agencies should design projects to follow the AquaticConservation Strategy. The Proposed Action is the Preferred Alternative.

Forest Health Protection; United States. Forest Service. Northern Region<br/><br/>Description: Preplant soil treatments were implemented to determine effects on populations of potentiallypathogenicFusarium and potentially disease-suppressive Trichoderma spp. as well as rootcolonization by these and other selected fungi on healthy-appearing, bare root 2-0 western white pine seedlings at the USDA Forest Service Nursery, Coeur d'Alene, Idaho. Soil treatments includedfumigation with dazomet, bare fallowing with periodic cultivation, steam treatment, fallowing withamendments of Trichoderma harzianum biocontrol agents (BioTrek® and University of Idahoisolates [UI]), and incorporation of two cultivars of winter Brassica cover crops followed by biocontrolamendments (UI). Soil Fusarium populations were significantly reduced by dazomet fumigation;fallowing with biocontrol amendments and incorporating winter mustard crops with biocontrolamendments resulted in significantly higher Fusarium populations. Trichoderma populations weresignificantly decreased by dazomet fumigation, bare fallowing and steam treatment. Incorporation ofBrassica crops did not significantly affect soli Trichoderma populations. Level of Fusarium rootcolonization was significantly reduced by dazomet fumigation and steam treatment. High levels ofroot colonization by rhizosphere-inhabiting isolates of Cylindrocarpon were common in some treatments. Assaying root colonization by selected fungi may supplement other parameters toevaluate effectiveness of soil treatments implemented to reduce pathogen populations and improveconifer seedling production.

Forest Health Protection; United States. Forest Service. Northern Region<br/><br/>Description: Tests were conducted at the USDA Forest Service Nursery, Coeur d'Alene, Idaho to evaluateeffectiveness of spring fumigation with dazomet to improve survival and performance of Douglas-firand western white pine transplants. Spring fumigation greatly reduced populations of potentiallypathogenic Fusarium and Pythium spp. Disease levels of container (plug+1) and bare root (2+1)Douglas-fir transplants were very low, regardless of soil fumigation. Fumigation reduced disease onbare root (2+1) white pine transplants, but did not improve survival of container (plug+1) white pinetransplants. Seedling height growth during the first year after transplanting was significantlyimproved by soil fumigation. Fusarium oxysporum was commonly isolated from soil and roots ofdiseased bare root transplants. Fusarium proliferatum was commonly isolated from the roots ofcontainer transplants. Soil fumigation may not necessarily improve survival and performance of alltypes of conifer transplants in nurseries. Sun, 28 Apr 2002 22:58:59 GMT
