      I42 Biomass and N, P and S in woodlands FOREST FLOOR BIOMASS The forest floor averaged 6 to 7 cm in depth, similar to that of ponderosa pine [ cm, Wooldridge (); or to cm, Klemmedson et aL ()]. Bulk density was g/ cm3, comparable to the forest floor under mixed conifers [ to g/cm3, Wooldridge ()].   Table 2 shows forest slash biomass waste pile composition -- material was relatively dry (9% to 18% moisture) with ash (% dry weight) and heat content (high heating value of 8, Btu/dry lb) comparable to virgin conifer slash, indicating minimal contamination with rock and soil. TABLE 2: Forest slash composition [Table omitted].

      The specific goal of the current study was to use nifH and amoA gene sequence analyses in combination with terminal restriction fragment length polymorphism (T-RFLP) profiles to compare the nitrogen-fixing and ammonia-oxidizing communities in unburned, moderately burned, and severely burned soils of a mixed conifer forest following the Cerro.   The Teakettle Experimental Forest (36°58′N, °02′W) is situated in the Sierra National Forest north of the North Fork of the Kings River, approximately 80 km east of Fresno, California ().The ha of Teakettle’s old-growth forest spans the upper montane red fir and lower montane mixed-conifer ecotone of the southern Sierra Nevada on the west side of the crest at an approximate.

    The westside mixed conifer forest types comprise the majority (57%) of the Plumas, and transition into eastside mixed conifer and eastside pine forest types, which are more rare (8% and 13%, respectively) (USDA, ). Logging across the forest has left many stumps of various species with visible fire scars. Land Use History.   Large-scale treatmentFour kilograms (dry weight 45% to 50%) of frozen conifer wood chips of various sizes and distilled water were added to air-permeable polyethylene bags ( by mm) to produce a final moisture content of 60 percent.

Provided for predicting weights of slash using tables of either slash weight per tree by d. b.h., or slash weight per square foot of tree basal area by d.

Slash weights include crowns (live and dead foliage and branchwood) and unmerchantable bole tips to 3- 4- and 6-inch diameter limits.

Abstract. no.4 Logging, Slash (Logging). Description: Preliminary curves for estimating crown and tree weight are given for madrone, black oak, and tanoak. These curves complement previously published slash weight tables for westside Sierra Nevada mixed conifers.

Tanoak crowns in trees 12 to 20 inches d.b.h. were two to three times heavier than black oak and madrone crowns. Keywords. Slash weight tables for westside mixed conifers / By Craig C.

Paper No. 48, 21 pp. Conifer slash from the clearcuttings amounted to about 45 percent of the total slash weight (table 1). Mater­ ials less than 4 inches in diameter from conifers, hardwoods, and litter made up 61 to 64 percent of the slash weight (table 2).

Using these equations, data tables listing the weight of logs for given diameters and lengths can be derived. Here, we show results for average values for red and white oaks, hickory, and yellow poplar (Table 2) and for mixed Southern pines (Table 3).

Log weight also can be estimated indirectly by converting a board foot measurement to tons. Conifer removal in interior woodland ecosystems of the western US is a common management treatment used to decrease fire hazard and shift woodlands to more historical states.

Woody material is frequently removed by skidding material off site and via slash pile burning. Assessing the long-term outcomes of seeding treatments after such ground disturbing activities is critical for informing. Slash pine is an important commercial conifer that grows on the coastal plains of the southeastern United States (∼ latitude 30°N) in soils that generally have shallow water seems to be less of a limiting factor to stand growth than nutrient (nitrogen) supply (Gholz et al., ).Stand fertilization with N, P, K, and ground limestone applied quarterly over 4 years caused an.

Fire in the sequoia-mixed conifer forest provides soft, friable soil on which the light-weight sequoia seeds fall and in which they are buried (Hartesveldt and Harvey ).

By consuming the accumulation of down branches, litter, and duff, fire allows the seed to reach mineral soil. Mixed conifer slash resulted in consistently higher grinding productivity by up to 52 percent (HA with 1-y-old feedstock) compared with hardwood whole trees (Table 2).

The average productivity for grinding mixed conifer slash was BDT/h, and the average productivity when grinding hardwood whole trees was BDT/h. A standard cord is a four-foot by four-foot by eight-foot stack of wood.; A board foot is a wood plank that measures one-inch by inches by one-inch.; MBF means thousand board feet.; A log rule is a tabular system used in determining the net volumetric yield of a log.; One cubic foot is equivalent to a foot by foot by foot solid cube of wood.

Mixed-Severity Fire in Dry Forest Types. Interest in forest fires in western North America centers mainly on the extensive dry forests of the North American Cordillera dominated by ponderosa pine (Pinus ponderosa), Jeffrey pine (P. jeffreyi), and mixed-conifer forests with pine and other conifer species (Odion et al., ).

Fires in these. The ponderosa pine and mixed-conifer forests of western North America have traditionally been considered adapted to a low- or low/moderate-severity fire regime (see Tables 1 and and2 2 for definitions of fire terms) –.There have been many large mixed-severity fires in western North America in recent years that have helped create widespread concern that fire exclusion has caused an.In mixed-conifer forest of Tehama County, California, habitat heterogeneity seemed to be the "key" to quality fawn rearing habitat, with fawns selecting forests with to foot ( m) tall trees, 20% to 39% canopy cover, and stumps, downed trees, or the bases of trees or snags as bedding sites.situations in the westside mixed conifer forest 41 4 Conifer reproduction species composition for five topoedaphic situations in the westside mixed conifer forest 43 5 Species composition of sunspot and grand fir heavy shade herbaceous vegetation for five topoedaphic situa- tions in the westside mixed conifer forest
