Plantation forests on mountainous areas in Tanzania, East Africa, were successfully
established in the 1950's. Harvesting started in the 1970's to meet increased national
timber demand. Current problems of unharvested areas and potential environmental
degradation are associated with uncontrolled harvests, mismatch of harvest systems to
site needs, and post-harvest practices....
This dataset includes species richness of native plants, pollinators and birds as well as 13 proxies for ecosystem services representing timber production, culturally-valued plants and animals, and regulating services tied to forest productivity. The data were collected from an experiment conducted in the Oregon Coast Range USA that sought to...
Hybrid poplar plantations (Populus trichocarpa x Populus deltoides) are a relatively new feature on the landscape in the Pacific Northwest of the United States, and these plantations may soon include genetically engineered trees. Meanwhile, many wild poplar populations (Populus spp.) are highly degraded due in part to logging, dams, grazing,...

More so than for
conifers, the time you spend managing
hardwoods will be returned to you
in increased wood production,
increased quality (and so value), and
shorter rotations.
Southwest Oregon presents an environment of hot dry summers, cool moist winters, and rocky, shallow soils. The establishment of conifer plantations in this region presents challenging problems for initial seedling survival and subsequent growth. Three areas of concern include early conifer growth after seedling establishment, growth of competing hardwoods within...
