Engelmann Spruce-Subalpine Fir (ESSF) forests of interior British Columbia have increasingly become the target of forest harvesting in the past 40 years. Over the past decade, increasing public concern over maintaining biodiversity and ecological health within forests has brought about two primary pieces of legislation—The Forest Practices Code of and The Forest .

Abstract The Rusty Blackbird (Euphagus carolinus) is a spruce-fir obligate that has experienced a steep population decline since the s.
spruce-fir forest type in the White Mountains and Pinaleño Mountains of Arizona. A New Mexico fir looper outbreak began in in the Sacramento Mountains of southeastern New Mexico causing elevated levels of fir mortality. Many other defoliating insects that have the potential to cause localized problems are not included in this Size: 13MB. Betula papyrifera is a broadly distributed tree in northern North America, occurring in Alaska, every Canadian province except Nunavit and some northern USA states. This species is often found in the southern part of the range of Black spruce dominance, and is an early invader after fire disturbance to Black spruce forests.
The Northern Forest is located at the convergence of the eastern broadleaf and the boreal forests, making it a complex mosaic of terrestrial, wetland and aquatic ecosystems that are variable in both pattern and process. Because the Northern Forest is at an ecotone, many species of plants and animals exist at the northern or southern limit of their geographic range. Abies amabilis / Vaccinium alaskaense is a widespread type on modal sites. Abies amabilis/Rubus lasiococcus, Abies amabilis/Streptopus roseus, Abies amabilis / Tiarella unifoliata, and Tsuga heterophylla-Abies amabilis/Blechnum spicant are herb-dominated types found in .

Although partial cutting has increased diameter growth in both even-and uneven-aged stands, diameter growth is inconsistent in uneven-aged stands because of the variability in. species of trees or shrubs in old-growth northern hardwood and spruce-fir stands.
Tree age is difficult to measure in old-growth or virgin stands because of the large size of the trees and the abundance of hollow or rotten boles.

Cutting, up to the time of certification, was based on the old plan, which led to serious overcutting of spruce-fir. The new plan allows heavy cutting in spruce/fir based on the allowable cut effect (ACE).
Tending is the term applied to pre-harvest silvicultural treatment of forest crop trees at any stage after initial planting or seeding.
The treatment can be of the crop itself (e.g., spacing, pruning, thinning, and improvement cutting) or of competing vegetation (e.g., weeding, cleaning). Planting. An invasive species is a species that is not native to a specific location (an introduced species), and that has a tendency to spread to a degree believed to cause damage to the environment, human economy or human health.
The term as most often used applies to introduced species that adversely affect the habitats and bioregions they invade economically, environmentally, or.

This massive conversion of mature forest to seedlings and sapling took some rather heavy cutting. The spruce-fir forest type, which was what brought the paper industry to Maine, covered million acres in (31% of the entire forest), down from 6 million acres inand million acres (44%) in.
Protecting gaps, hardwoods, wolf trees, and old-growth remnant trees during thinning of other partial cutting is likely to promote the majority of epiphytic macrolichens in young conifer forests. Because these features are easily recognized on aerial photos and on ground by land managers, it is practical to manage for forest structures that.
