Young stands 20 to 40 years old (some in burned areas) in southern Oregon and northern California may be pure mountain hemlock and quite dense (9, to 24, trees/ha, or 4, to 10,/acre) (11). In Oregon, mountain hemlock forests typically regenerate slowly after they are clearcut. with conifer forest (Mueggler ; Bartos & Campbell ). Heavy grazing by livestock and wildlife has reduced the density and overall vigor of aspen suckers and root sys-tems, further retarding regeneration (White et al. ). There is signiﬁcant interest across northern California in the restoration of aspen stands degraded by conifer.
Conifers: brown patches. Brown patches in conifers can be caused by a number of reasons. Pests or diseases are responsible for some cases, but others may be caused by growing conditions or routine operations such as trimming. Fire legacies impact conifer regeneration across environmental gradients in the U.S. northern Rockies conifer forests in the U.S. northern Rockies, spanning a four-degree south to north latitudinal gradient classiﬁed as ‘‘unburned’’ if they did not burn in either , , or in the or .
On low-severity burned sites, little mineral soil was exposed, and some woody fuels less than 1 inch ( cm) in diameter remained [,]. When older low- and high-severity burned clearcuts were compared, burn severity did not affect thimbleberry abundance . Project Methods We will use a set of long-term permanent plots () across nine National Forests in AZ and NM to examine past and present conifer regeneration patterns. We will examine growth, mortality, and regeneration records on plots dominated by ponderosa pine. For contemporary conifer regeneration data, we will supplement the permanent plot sites with additional sites that have.

Six years after logging and hand planting with Douglas-fir, stocking and growth on cutblocks where slash had been broadcast burned was compared with that on similar unburned cutblocks.
Conifers were seven times more plentiful on the unburned areas, the average height of the. You can easily get "Burned" with FREE Pdf, ePub, Mobi, Audiobooks and Tuebl formats.

Publisher: Berkeley, Calif.: Dept. of Agriculture, Forest Service, Pacific Southwest Forest and Range Experiment Station, Year: Volcanic soils with mixed conifer vegetation had a ratio (burned to unburned soils) of at most 038, and granitic soils with ponderosa pine vegetation had a ratio of 0 Wildfire effects on understory shrubs and herbs, regeneration of the seedling and sapling size classes, and downed and dead fuels were assessed in a mixed conifer stand located in the Lake Tahoe.
It is in pure stands or as a major component in Red Fir (Society of American Foresters Typeand also in the following types: Mountain Hemlock (Type ), White Fir (Type ), Lodgepole Pine (Type ), Pacific Douglas-Fir (Type ), Sierra Nevada Mixed Conifer (Type ), and California Mixed Subalpine (Type ).
On erodible granitic soils of the Klamath National Forest, hand planted Douglas-fir seedlings were 7 times more numerous on unburned than on burned plots, 6 years after planting.

Conifers are commonly evergreen and reproduce through the formation of cones. Their growth rate is generally divided into three categories. Slow-growing conifers grow less then 12 inches per year. A medium or moderate growth rate is between 1 and 2 feet per year.
Fast-growing conifers grow at. Conifer Regeneration on Burned and Unburned Clearcuts on Granitic Soils of the Klamath National Forest: Ryan, Bill C. Computation of Times of Sunrise, Sunset, and Twilight in or Near Mountainous Terrain: Rice, R.M.; S.A.
Sherbin Estimating Sedimentation From an Erosion-Hazard Rating: California spotted owls use mostly forests burned by low-/moderate-severity fire or unburned forests for nesting and roosting, and they preferentially select unlogged, high-severity fire patches occurring in older conifer forest for foraging (hunting) (Bond et al., ), given the rich small-mammal prey base in complex early seral forest.

), in Pinus ponderosa. Median conifer density exceeded stems ha–1 out to a distance of m from an edge before declining farther away. The strongest controls on regeneration were distance to live trees and soil parent material, with skeletal coarse-grained soils supporting lower densities ( stems ha–1) than fine-grained soils (– stems –1ha).
Clearcuts are dryer than intact stands (Tappeiner et al., ), thus many conifer clearcuts may be too dry for red-backed voles (D.E. Pearson, personal communication), which are known for their.Most labels on conifer plants list a 10 year size, but conifers do not stop growing after 10 years.
Assume the 20 year size to be double the 10 year size. Cultural conditions (sun, rain, soil compaction, fertilizer, etc.) affect the growth rate of any given plant.clearcuts at Miller Creek and on 7 clearcuts at Newman Ridge.
At Miller Creek, seedbed categories were (1) logs, (2) rock, (3) unburned, (4) rotton wood, (5) mineral soil, (6) scorched duff, and (7) burned mineral soil. The percent of each seedbed type on 34 to 86 circular plots, m2 in size, was estimated.
At Newman Ridge, the percent.
