    Douglas-fir forest covers more of Oregon than any other, primarily on the west side of the Cascades, though Douglas-fir trees are found in the mixed conifer forest types as well. These forests are dominated by their namesake tree, but in moister and riparian areas there are also western hemlock, western redcedar, Pacific yew, bigleaf maple, and. The Western juniper canopy cover layer for Oregon is linked directly here. Accuracy notes: The Oregon juniper and tree maps have relatively high precision in depicting spatial patterns and relatively high accuracy in predicting the range of cover values found in plot data. Other tree species are sometimes confused for juniper in the maps, and.

Landscape Patterns of Pre-logging Forest Conditions in Western Oregon 1. Introduction Large-scale disturbances have been a prevalent force in natural landscapes for millennia.

In the forests of the Pacific Northwest, fire has been the dominant force creating, maintaining, and destroying the rich. Using historical maps and tools provided by GJS, the spatial patterns of pre-logging forest conditions were quantified for three landscapes in western Oregon.

The spatial coincidence between forest patches and topographic features was determined for slope Cited by: 1. From the Forest Type Map of Oregon, Rasmussen and Ripple () estimated that 72% of the prelogging forest landscape of the south central Oregon Coast Range comprised the large conifer class.

Using Public Land survey notes and the Land Class Map, Teensma et al. () reported that 62% of the forests in the Coast Range in Cited by: Graduation date: Using historical maps and tools provided by GJS, the spatial patterns of\ud pre-logging forest conditions were quantified for three landscapes in western\ud Oregon.

The spatial coincidence between forest patches and topographic\ud features was determined for slope gradient, aspect, elevation, and distance\ud from streams. Ecological Modelling () – Design and evaluation of a forest landscape change model for western Oregon Steven L.

Garman∗ Department of Forest Science, Oregon State University, SW Jefferson Way, Corvallis, ORUSA. An efficient model for simulating forest landscape change in western Oregon, called LandMod, was developed by scaling the PNWGap gap model to operate at a coarser resolution.

Scaling was achieved with the statistical estimation of gap-model predictions of demographics for 5-cm size-classes and a 5-year time step, and the use of mean. Data were tabulated, mapped, and digitized as new GIS layers for purposes of comparative analysis.

An abundance of useful historical evidence was found for reconstructing precontact vegetation patterns and human burning practices in western Oregon. The data also proved useful for documenting local and regional forest fire histories.

Fire hazard has increased throughout much of western Oregon and Washington because of the increase in area of young forest plantations (Perry Sa; Franklin et al. ~ ~. It has been known for many years that plantations are more vulnerable to crown fires than are healthy old- growth forests (e.g., Andrews and Cowlin ; Cowlin et al.

Tree Seed Zones for Western Oregon HISTORY OF SEED ZONES Foresters in western Oregon gained an early appreciation for the importance of seed source through large scale tree planting projects in the Coast Range ('s's) following major forest fires.

Through the s, the forest-products industry was an economic mainstay of western Montana, Washington and Oregon, Northern California, and the Idaho Panhandle. Patterns of. The national forests in the Douglas-fir region of western Oregon and Washington were a primary focus of this effort, because of the massive timber volumes present in the old-growth forests in these highly productive forest landscapes.

The approach adopted was a specific landscape-level application of clear-cutting. The Augusta Creek project was initiated to establish and integrate landscape and watershed objectives into a landscape plan to guide management activities within a hectare (19,acre) planning area in western Oregon.

Primary objectives included the maintenance of native species, ecosystem processes and structures, and long-term ecosystem productivity in a federally managed landscape. This forest will provide the range of forest conditions that will need to exist to achieve the goals for all resources.

The conservation zone is likely to require at least 30% of the landscape in order to achieve the conservation goals under the plan. Northwest Oregon state forests comprise about three percent of Oregon’s forest land.

In western Oregon alone, famous forest fires include the Biscuit, Tillamook (four times), Yaquina (two times), and Nestucca fires, each denud toha (50, toacres).

These events also denuded many river and stream corridors, often for several decades, affecting generations of fish and waters where they occur. We specialize in adding useable living space to your home by designing outdoor spaces that are beautiful and functional.
