Download or read book Precommercial Crop tree Thinning in a Mixed Northern Hardwood Stand written by Nancy G. Voorhis and published by . This book was released on 1990 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The effectiveness of precommercial crop tree thinning was investigated by thinning crop trees of paper birch, yellow birch, and sugar maple to two intensity levels at 8 years of age. Analysis of covariance on post thinning growth measurements taken 7 years later indicated a significant increase in diameter and crown-diameter growth, with the pattern of response varying by species. The study suggests that a uniform crop-tree thinning treatment for a stand composed of species with varying tolerances will rarely produce the best response for all the species.

Download or read book Forest Dynamics Growth and Yield written by Hans Pretzsch and published by Springer Science & Business Media. This book was released on 2009-06-19 with total page 670 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to improve the understanding of forest dynamics and the sustainable management of forest ecosystems. How do tree crowns, trees or entire forest stands respond to thinning in the long term? What effect do tree species mixtures and multi-layering have on the productivity and stability of trees, stands or forest enterprises? How do tree and stand growth respond to stress factors such as climate change or air pollution? Furthermore, in the event that one has acquired knowledge about the effects of thinning, mixture and stress, how can one make that knowledge applicable to decision-making in forestry practice? The experimental designs, analytical methods, general relationships and models for answering questions of this kind are the focus of this book. Given the structures dealt with, which range from plant organs to the tree, stand and enterprise levels, and the processes analysed in a time frame of days or months to decades or even centuries, this book is directed at all readers interested in trees, forest stands and forest ecosystems. This work has been compiled for students, scientists, lecturers, forest planners, forest managers, and consultants.

This book was released on 2021-09-01 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: To facilitate sustainable management of logged forests in the Caribbean, forest authorities of Belize, Guyana, Suriname, and Trinidad and Tobago, jointly with the Food and Agriculture Organization of the United Nations and the University of Hamburg as a scientific partner, implemented the regional project “Ensuring Long-Term Productivity of Lowland Tropical Forests in the Caribbean” financed by the German Federal Ministry of Food and Agriculture. The main objective of the project was to support the sustainable management of logged forests to maintain productivity and prevent further degradation. For this purpose, extensive field studies were conducted in the project countries, which resulted in silvicultural recommendations presented in this publication. The project findings revealed that the application of general sustainable forest management protocols for tropical production forests that set limits on harvesting does not necessarily ensure sustained productivity if the composition and management of the residual stand are not considered. The ratio of the number of harvested trees to the remaining future crop trees can provide a simple indicator of the sustainability of harvest. If the current harvest exceeds the number of future crop trees, the harvest is not sustainable. As a rule of thumb, at least one, preferably two future crop trees per harvested tree should be retained for future use. Protection of future crop trees can be a simple and practical approach to prevent high grading and degradation of the forest growing stock. The importance of reduced impact logging to reduce unnecessary damage to the future crop trees and for sustainable forest management, in general, is stressed.

Available in PDF, EPUB and Kindle. Book excerpt: The Principles of Forest Yield Study: Studies in the Organic Production, Structure, Increment and Yield of Forest Stands reviews the progress that has been made in the field of forest yield studies, especially those concerning the organic production, structure, increment, and yield of forest stands. Topics covered include woody growth as part of the total produce of plant societies; growth and form of forest trees; constitution and development of stands; and forest stand structure, increment, and yield in relation to silvicultural treatment. This book is divided into five sections and begins with an overview of the history of forest yield studies, as well as the place of forest yield theory in forest science. Research objectives and methods employed in forest yield studies are outlined. The discussion then turns to the interactions between soil, climate and plant production; the social structure of tree crops; growth performance of tree crops in relation to site; and disturbances in the normal trend of increment. The use of fertilizers for amelioration and treatment of forest soils are discussed from the standpoint of yield studies. This monograph will be a useful resource for practitioners in forestry, the natural sciences, plant physiology, soil science, and meteorology.
