Control in Woodlands Operations,crease, the need for tighter controls on operations increases in direct proportion.

Soil Compaction,forest soils are typically porous well-aggregated mixtures of mineral soil particles and organic material and it is this porous nature that makes the forest soil particularly susceptible to compaction by logging equipment.

Forest Roads in a Staggered Ownership Setting,ministrative tools to allow and promote the establishment and continuing maintenance of an adequate forest road network. In some countries, especially those with small forest areas intermixed with agricultural land, the state provides the roads, which then become part of the public road network.

Introduction,It was pointed out in Part I that the basic economic problem in forest management is to achieve the most efficient use of productive resources. It is the need to manipulate and use the forest resource with a minimum of human activities that is the concept of operational efficiency with which this book is concerned.作者: 群島 時(shí)間: 2025-3-28 04:02
Operational Efficiency,Operational efficiency is defined as the efficient utilization and economical management of the resource (forest). The aim of operational efficiency with which this book is concerned is to economize the human activities in forestry. Human inputs or activities are manipulated to meet certain goals or objectives.作者: Pde5-Inhibitors 時(shí)間: 2025-3-28 07:07 作者: BLANC 時(shí)間: 2025-3-28 12:38
