Download or read book New Mexico Vegetation written by William A. Dick-Peddie and published by UNM Press. This book was released on 1993 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Originally published in 1993 and now available for the first time in paperback, this book remains one of the few authoritative vegetation compilations for a western state. It is the first comprehensive study of the biological history and evolution of New Mexico's vegetation and includes a detailed account of the distribution of plant communities in the state today. Discussed are the following major types of vegetation: tundra and coniferous forest, woodland and savanna, grassland, scrubland, riparian, and wetlands. For each type, information is provided on the principal plant species. In addition, for each vegetation type special attention is given to describing how plants sharing a common location interact and, in particular, how human activity impacts on each type. Much of New Mexico's vegetation is in some stage of succession as a result of human-initiated disturbances such as fire, logging, and livestock grazing. The book ends with a detailed description of species of special concern and what is being done to preserve examples of vegetation types within the state. A map of the state's vegetation, including types not found on existing maps, accompanies the book. The classifications of vegetation employed here are easily recognizable in the field, which makes them of greater use to the public as well as to resource managers, researchers, and students.

This book was released on 1993 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conifer productivity in western North America is often severely inhibited by competing vegetation. Abies concolor [Gord. and Glendl.] Lindl. (white fir) is an important species over much of this area, yet little information is available on response of A. concolor to vegetation management treatments. We revisited two sites in the northern Sierra Nevada to assess the responses of naturally regenerated A. concolor saplings to vegetation recovery 8-9 years after release treatments. Treatments caused major and persistent shifts in vegetation structure and composition on both sites. Differences in individual tree growth within treatments were strongly correlated with structure and composition of neighboring vegetation, even where no treatment effects were observed. At Rice Canyon, height growth of trees was still 270 to 380 percent of controls after 8 years. At Sattley, positive growth responses had disappeared after 6 years. We attribute different site responses to better site quality at Rice Canyon and poorer success of treatments at controlling competitors at Sattley. Great variability in response between sites illustrates the strong effect of site characteristics on response to release treatments and the importance to managers of anticipating such differences before making treatment decisions.

Available in PDF, EPUB and Kindle. Book excerpt: A land-classification system based upon potential natural vegetation is presented for the coniferous forests of central and southern Utah. It is based on reconnaissance sampling of about 720 stands. A hierarchical taxonomic classification of forest sites was developed using the habitat type concept. Seven climax series, 37 habitat types, and six additional phases of habitat types are defined and described. A diagnostic key, using conspicuous indicator species, provides for field identification of the types.

Available in PDF, EPUB and Kindle. Book excerpt: Mycorrhiza will be the focus of research and study for the coming decade. Successful survival and maintenance of plant cover is mostly dependent on mycorrhization. During the last decade about ten books have appeared on various aspects of mycorrhiza, including two on methodology. The present book has been compiled to give a complete and comprehensive description of the topic to the students and researchers in botany, applied mycology, biotechnology, forestry and agriculture. The book will also be useful to planners dealing with biofertilizers and forestation. Besides topics of academic interest, the volume includes several aspects which are unique and are written about for the first time, e.g.: Arbuscular Mycorrhizal symbiosis - recognition and specificity; Mycorrhizal Integration and cellular compatibility between Endomycorrhizal symbionts; Cost - economics of existing methodology for inoculum production of vesicular-arbuscular mycorrhizal fungi; Mycorrhiza: Ecological Implications of Plant interactions; Outplanting performance of mycorrhizal inoculated seedlings; Fluorescence microscopy in mycorrhiza studies and Ectomycorrhizal fungi as experimental organism. Other aspects not mentioned above include most recent reviews concerning vesicular-arbuscular mycorrhiza and ectomycorrhizae. The different review chapters have been written by world authorities in their respective specialisations giving more up to date information than is provided anywhere else. This book deals with all major aspects of mycorrhiza, giving structure, ultrastructure, ecology and applications in agriculture and forestry.
