      Whether you want trees or mountains or a state outline or flower, here are 69 tattoos that will give you some great ideas, and a bunch of artists in Oregon and the Pacific Northwest who will help. Jack Nisbet first told the story of British explorer David Thompson, who mapped the Columbia River, in his acclaimed Sources of the River. That book set the standard for research and narrative biography for the region. Now Nisbet turns his attention to David Douglas, the premier botanical explorer in the Pacific Northwest and other areas of western North America.4/5(1).

    view of the dynamics of residual trees, advance regeneration, plant-ed seedlings, and new germinants. Such studies are needed in the Douglas-fir region of the western United States where, despite little experience with producing and maintaining two-aged or multi-aged stands of Douglas-fir, the Northwest Forest Plan mandates a mini-. Douglas-fir regeneration may be affected less by madrone duff than by other influences of madrone trees. Citation: Minore, Don. Madrone duff and the natural regeneration of Douglas-fir. Res.

    Patch-scale conifer regeneration density (72%–80% Douglas-fir (Pseudotsuga menziesii (Mirb). Franco)) varied widely, from to stemsha –1. Median densities were and stemsha –1 2 and 4 years postfire, respectively, i.e., ∼12 times prefire overstory densities ( stemsha –1). Because of the complex burn mosaic. Douglas firs yield more high-quality construction lumber than any other tree in the world. Most intriguing of all, perhaps, is that the story of the Douglas fir has gone untold. Douglas Fir fills this literary gap and presents an engaging profile of the Douglas fir and its relationship to people, commerce, culture, and wilderness. Contributors.

The Douglas-fir region of the Pacific Coast of northwestern North America (west of the Cascade Range crest) is famous for its high productivity, dominance by evergreen conifers, and the massiveness of the older forest stands (Waring and Franklin ; Franklin and Dyrness ).A mild, wet climate provides favorable conditions for tree growth, but the massiveness of the forest is also.

David Douglas is one of the best-known botanists in Oregon history, primarily because of the tree that bears the common name Douglas-fir (Pseudotsuga menziesii, once Pinus douglasii), the Oregon state humble beginnings and through fortunate circumstance, he became a highly regarded collector of Pacific Northwest plants and animals, which he sent to the Royal Botanic Gardens, Kew, in.

Wildfires in the Pacific Northwest (Washington, Oregon, Idaho, and western Montana, USA) have been immense in recent years, capturing the attention of resource managers, fire scientists, and the general public. This paper synthesizes understanding of the potential effects of changing climate and fire regimes on Pacific Northwest forests, including effects on disturbance and stress interactions.

Douglas Fir, Pseudotsuga menziesii [ ]. Coastal Douglas-fir is a seral or early successional species, while Rocky Mountain Douglas-fir can be both a seral and a climax species (Hermann and Lavender, ).

In Washington, the division between the two varieties is generally thought to occur at the break in the natural distribution of Douglas-fir in the Okanogan Valley (Little ). Additional seed sources for Douglas-fir and western redcedar were identified in these areas to augment the genetic diversity of local seed sources.

cn; Pacific Northwest Forest and Range Experiment Station (Portland, Or.) cn. Olympic National Park is an American national park located in the State of Washington, on the Olympic Peninsula. The park has four regions: the Pacific coastline, alpine areas, the west side temperate rainforest and the forests of the drier east side.

Within the park there are three distinct ecosystems which are subalpine forest and wildflower meadow, temperate forest, and the rugged Pacific. The Pacific Northwest offers a veritable feast for foragers, and with Douglas Deur as your trusted guide you will learn how to safely find and identify an abundance of delicious wild plants.

To determine temporal patterns of Douglas-fir establishment following stand-replacing fire, increment cores were obtained from trees in 18 mature and early old-growth forests in western Washington and northwestern Oregon, USA.

Each of the stands showed continuous regeneration of Douglas-fir for many decades following initiating fire. 1 72 Pacific Northwest Forests Small-scale disturbances in forests (e.g., gaps created by the loss of one to a few trees) tend to facilitate the replacement of Douglas-fir by shade-tolerant species.

An old-canopy, Douglas-fir tree that dies as part of natural tree mortality is likely to be replaced by hemlock or cedar seedlings expanding into.(Washington DNR, Webster Nursery) and John Kitchen (Pacific Regeneration Technologies) for contributing seedling pictures.
