Populations from humid regions registered a higher sensibility to reduced rates of nicosulfuron than populations from subhumid regions. This effect was visualised in the values of regression coefficient of the non-linear models (relating fresh weight to nicosulfuron rate), and in the time needed to obtain a 50% reduction of photosynthesis rate. In the Ma Federal Register, a procedure was outlined for the submittal to EPA of privately developed models. After extensive evaluation and scientific review, these models, as well as those made available by EPA, have been considered for recognition in the Guideline.
Species richness throughout the site was low (13 species). ANOVAs run on species other than Atlantic whitecedar between elevation zones, with the exception of pepperbush (PcO) and blue iris (Iris virginica) (P=), did not return significant P-values. As stated previously, mean percent cover for pepperbush was highest in the highFile Size: 10MB. Populus is composed of ~35 extant species in six sections (Abaso, Aigeiros, Turanga, Leucoides, Tacamahaca, and Populus) and has a mostly north temperate distribution (Eckenwalder, ; Hamzeh et al., ) Poplars are fast growing, deciduous, dioecious trees with serrate leaf margins and wind pollinated catkin inflores cences.

Forest Research Laboratory.] -- Three equations for predicting tree height as a function of diameter (outside bark) at breast height are presented for six species found in coastal regions of the Pacific.

Hatchlings of the giant Pacific octopus (Enteroctopus dofleini)—one of the two largest octopus species—weigh g ( oz) on average (Cosgrove & McDaniel, ). At the other extreme are nautiluses, which upon hatching typically have a shell diameter of 25 mm (1 in) or more (depending on the species), the largest hatchling size.
Quarterly stumpage prices from to obtained from cut and sold reports for USDA Forest Service Regions 1, 4, 5, and 6 (Northern, Intermountain, Pacific Southwest, and Pacific Northwest, respectively) were analyzed to establish the presence and extent of national forest timber markets.
The adoption of the retention system in much of coastal British Columbia, Canada, has brought with it concern over the windfirmness of the retained trees.
The present state of knowledge concerning windthrow risk factors is inadequate for the purposes of risk prediction in partial cuts and in structurally complex forests, such as those that exist in Clayoquot Sound.

The primary objectives were to: (1) test the efficacy of 12 shock graphs for hardwood and coniferous species classification at the leaf level, (2) exploit intrinsic patterns of leaf orientations associated with the branch-level for species discrimination between eastern hemlock (Tsuga canadensis) and eastern white pine (Pinus strobus), and (3.

Rationale; In recent years, the Pacific Northwest has been the focus of intensive research and controversy over the effects of land use on hillslope erosion, water quality, and fish habitat. Most sediment-monitoring studies have been performed on small, experimental watersheds, but these results cannot be directly extrapolated to larger basins.

However, in the southern part of its range, including interior California, it also is a shrub up to 5 m tall, which is treated as var. breweri (Engelm.) Jepson. Missouri. Bark correction equations have been prepared for Douglas-fir Traditional to provide more accurate estimates of wood content in trees.
Douglas-fir volume tables have been reduced to equations to speed-up computer calculations of volumes. Simplified height-diameter relationships are now available for western species subject to.

(Rosaceae), comprising roughly woody species, includes several economically important fruit and nut crop species of temperate regions, such as plums/prunes, peaches, cherries, and almonds, as well as many ornamental species and numerous wild species of ethnobotanical importance.As forest harvesting shifts from old-growth to second-growth stands, profitability is becoming an important issue.
In a cooperative project involving Forest Engineering Research Institute of Canada (FERIC), University of British Columbia (UBC) and Canadian Forest Service - Pacific Forestry Center, a model was developed to predict economics of second-growth harvests.
