The purpose of this handbook is to identify the inventory-derived information that may be needed for the 1999 Resources Planning Act assessment and National Forest planning, and to provide guidance to ensure that inventories of land, soil, timber, forage, water, air, fish and wildlife, aesthetics, recreation, wilderness, and energy and mineral resources are conducted in an effective way.
Forest inventory terms are defined and arranged alphabetically, and in some cases, grouped in families of terms.
Multi resource inventories, growth projection, sampling techniques, and application of computers in forest resources inventory.
Tropical inventories, biomass estimation, product estimation, and list of contributed papers on diameters distribution, yield regulation, plot verses point sampling, field instruction for point sampling are covered in volume II.
Field Inventory Procedures.
This article deals with the inventory and assessment of Tree Outside Forest (TOF) - inventory being the process of finding out quantitatively and qualitatively how much of a resource there is, and assessment the process of putting the inventory data into a context and assigning values to the resource. The focus is on inventories for large areas such as provinces, countries or regions, as opposed to the more common studies for smaller areas such as farms or groups of farms. After discussing definition and classification of TOF, the article outlines survey options. Particular reference is made to experiences and examples from Latin America.
This paper describes the field inventory process as well as covers the aspect of what to be measured.
Peer reviewed. Covers general principles for achieving integration, types of integration (multilocation, multilevel, multiresource and temporal) and integrated inventory planning, implementation, and maintenance.
Peer reviewed. Covers in detail and with worked-out examples designs for the inventory of stands and forests. For stands, random sampling, line transects, ricochet plot, systematic sampling, single plot, cluster, subjective sampling and complete enumeration are discussed. For forests inventory, the main categories are subjective sampling, inventories without prior stand mapping, inventories with prior stand mapping, inventories using existing stand information, and complete enumeration. Systematic sampling, stratified sampling, equal probability sampling, probability sampling proportional to size, etc. are presented.
The need for multi-resource information for management decisions is presented. One of the ways of collecting this data is through integrated inventories. Advantages and disadvantages of integrated efforts are outlined. In addition a review of present and probable future multi-resource inventory systems in the United States is presented.
These guidelines provide basic information on Multipurpose Resource Inventories (MRI) for the inventory planner and the decision maker at the provincial or national level although the instructions are useful at the local level as well. The guidelines are based upon the world wide survey, a literature review and the personal experiences of nearly 60 contributing co-authors. The need for MRIs, the information requirements, support structure, and the design and implementation issues in depth discussed.
This paper covers the following: 1. What are Multiple Resource Inventories (MRI) - why needed, where needed, when needed? 2. What are the requirements - information needs assessment, support, and information management structure? 3. What are the design considerations? 4. How do we implement MRI? 5. What are the challenges and recommendations?
Principle of forest land inventory, consideration of environmental factors, survey procedures, forest land evaluation, quantitative and characterization factors rating.
