Available in PDF, EPUB and Kindle. Book excerpt: Atriplex canescens (Pursh.) Nutt. is the most widespread species of perennial Atriplex in North America. Throughout its distributional range, A. canescens shows considerable between-population variation. Some of this variation may be due to phenotypic plasticity but most of it appears to be genetic. Mutations, polyploidy, introgressive hybridization, and segregation from interspecific hybrids all appear to have contributed to its extensive heritable variation. Polyploidy is unusually common with numerous chromosome races (2x, 4x, 6x, 8x, 10x, 12x, 14x, 20x). Fourwing saltbush is widely used for reclamation plantings. Proper identification is important to the utilization of fourwing saltbush in such plantings. While many of the races have been formally named as varieties, others have not. Even though differentiated by ploidy, chemical constituents, geographic distribution, and statistical distribution of morphological characters, races may lack sufficient diagnostic characters to allow facile identification, at least in the herbarium. Rather than combining unnamed races under those that do have a taxonomic name, it seems better at present not to use the formal infraspecific categories in treating the fourwing saltbushes, but to consider them all as races. Seed transfer should be within the geographical distribution limits of each race. The most common race, by far, is Occidentalis. We recommend four overlapping seed transfer zones for race Occidentalis in the United States: (1) Northern Intermountain, (2) Western Great Plains, (3) Colorado Plateau/Great Basin/Columbia Basin, and (4) Southwestern. Source seed populations from near the planting sites generally do well; and populations generally perform better when moved south and/or to lower elevations than when moved north and/or up in elevation.

This book was released on 2012-12-06 with total page 637 pages. Available in PDF, EPUB and Kindle. Book excerpt: Natural grasslands, pastures and meadows are among the vegetation types most frequently investigated with phytosociological methods. This was one of the reasons why volume 13, Application of vegetation science to grassland husbandry and agriculture, edited by W. Krause, appeared as one of the first volumes of this handbook. It appeared under the chief editorship of Prof. R. Tiixen and in his time main emphasis of the handbook was placed on Ziirich-Montpellier methods and the European vegetation. When we redesigned the handbook we felt the need to include other methods and aims of grassland analyses as well as a more global coverage of grasslands. Especially the natural dry and semidry areas of the world needed to be covered. was very fortunate in getting Prof. Tueller of the University of Reno I Nevada as an editor for this volume. He and the colleagues he motivated to compile volume 14 on Application of vegetation science to rangeland analysis and management have created a truly global coverage of the topics interesting for vegetation analyses in natural grasslands. Since volume 13 covered the problems of anthropogenically created grasslands, this topic was not expressly treated in order to avoid duplication. For the same reason no specific attempt was made to get more papers from Europe and the temperate forest region in general. The cooperation with Dr. Tueller has been very rewarding for me.

Download or read book Fourwing Saltbush Atriplex Canescens written by Clinton H. Wasser and published by . This book was released on 1986 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: A plant materials report on fourwing saltbush (atriplex canescens) is provided as Section 7.5.3 of the US Army Corps of Engineers Wildlife Resources Management Manual. The report was prepared as a guide to assist the Corps District or project biologist with the selection, cultivation, and management of suitable plant materials for wildlife and habitat development programs. Topics covered include description, distribution, habitat requirements, wildlife value, establishment, maintenance, and cautions and limitations. Fourwing saltbush is a semievergreen shrub that is widely distributed in the Western United States. Saltbush provides important forage and cover for wildlife, and plants are used for windbreak plantings, erosion control, restoration of big game winter range, and reclamation of disturbed lands. The distribution and diagnostic characteristics of fourwing saltbush are described, and habitat requirements and adaptations are discussed. Procedures for site selection, site preparation, propagule selection, and planting are given under the heading Establishment. Maintenance requirements and tolerances to land management practices are discussed.
