This book was released on 2018-08-09 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Computer Simulation of White Pine Blister Rust Epidemics, Vol. 1: Model Formulation The fungus produces fusiform swellings and cankers on the branches and stems of susceptible trees. The cankers grow parallel (up and down) with the stems and branches at a rate of about 5-13 cm each way each year. The growth around the stem is about 3 cm each way each year, making the stem encirclement rate about 6 cm per year. Factors such as site, genotype of the host, and genotype of the rust may cause variation in the encirclement rate. Thus, the time needed to produce a canker that girdles a stem varies with the growth rate of the tree, growth rate of the rust, the diameter of the tree at the point that the fungus reached the stem, and possibly other genetic and environmental factors. This period can vary from a few weeks on small seedlings to 40 years or more on mature trees. After trees are girdled (even seedlings) it takes 3 to 10 years for the tree to die. In many cases, trees do not die entirely. Tops are lost; branches die; and growth slows down as a result. But, it can be generally said that there is little effect on growth until shortly before death. Heavy infection can cause defoliation of Ribes plants, but, in most areas in most years, the infection is not of sufficient magnitude to cause obvious damage to the Ribes population.

Download or read book Whitebark Pine Communities written by Diana F. Tomback and published by Island Press. This book was released on 2001 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: Whitebark pine is a dominant feature of western high-mountain regions, offering an important source of food and high-quality habitat for species ranging from Clark's nutcracker to the grizzly bear. But in the northwestern United States and southwestern Canada, much of the whitebark pine is disappearing. Why is a high-mountain species found in places rarely disturbed by humans in trouble? And what can be done about it.Whitebark Pine Communities addresses those questions, explaining how a combination of altered fire regimes and fungal infestation is leading to a rapid decline of this once abundant -- and ecologically vital -- species. Leading experts in the field explain what is known about whitebark pine communities and their ecological value, examine its precarious situation, and present the state of knowledge concerning restoration alternatives. The book. presents an overview of the ecology and status of whitebark pine communities offers a basic understanding of whitebark pine taxonomy, distribution, and ecology, including environmental tolerances, community disturbance processes, regeneration processes, species interactions, and genetic population structure identifies the threats to whitebark pine communities explains the need for management intervention surveys the extent of impact and losses to dateMore importantly, the book clearly shows that the knowledge and management tools are available to restore whitebark pine communities both locally and on a significant scale regionally, and it provides specific information about what actions can and must be taken.Whitebark Pine Communities offers a detailed portrait of the ecology of whitebark pine communities and the current threats to them. It brings together leading experts to provide in-depth information on research needs, management approaches, and restoration activities, and will be essential reading for ecologists, land managers, and anyone concerned with the health of forest ecosystems in the western United States.
