Index selection provides an efficient means of conducting selection on multiple traits by combining information on economic value,
heritability, and the genetic and phenotypic correlations between traits to improve overall merit. The use of this method in forestry has been hampered by the lack of knowledge of the relative importance...

In the tropics, widespread deforestation and conversion of primary forests to agricultural and pasture lands has resulted in losses of composition, structure, and functions of forest landscapes. Deforestation in the tropics is typically preformed via slash-and-burn practices; the byproducts from combustion have been identified as the second-highest form of anthropogenically...
A sustainable landscape is more than exterior decoration. By using less water, fertilizer, and pesticides than a traditional
landscape, it has minimal impact on the environment. Thus, it is both aesthetically pleasing and environmentally sound.
Creating a sustainable landscape means working toward a thoughtful balance between resources used and results...
Growing native plants can be rewarding in many ways. They add beauty
with colorful flowers, foliage, texture, and scents. If planted in a suitable habitat, native plants are well adapted to our soils and climate. This reduces the need for supplemental water (once established) and maintenance, and makes it easy...
Greater Sage-grouse (Centrocercus urophasianus) habitat research has historically focused on fine-scale (0.007 - 0.032 ha) vegetation structure and composition immediately surrounding sites selected by birds. However, little work has evaluated vegetation attributes important for Greater Sage-grouse at a landscape-scale or identified landscape attributes that influence habitat use patterns. Habitat use...
This pocket guide highlights fire-resistant plants that thrive in Willamette Valley growing conditions. It recommends groundcovers, perennials, shrubs, woody vines, and trees. There are too many annual plants available to list them all. In general, annuals are considered fire-resistant if they are kept well irrigated.
