The systematic measurement of sample plots in stands of growing timber provides the data for the compilation of yield tables and other estimates of increment which are essential to the economic management of woodlands. In order that such measurements shall be strictly comparable, both as between one sample plot and another, and within the same […]
This bulletin is a study in forest mensuration which has arisen out of investigations into the timber content of British woodlands. It deals primarily with the relationship that exists between the volume of a tree and its sectional area at breast height; a relationship here called, for convenience, the volume-basal area line. Studies of this […]
This Field Book provides tables for estimating the volume of logs using the traditional mid-diameter method. Although it is a very accurate method, it becomes less accurate as the length increases. The volume is derived from the product of the length of the log and its mean cross-sectional area. In practice it is the diameter […]
The methods of measurement described in this Booklet are intended to be used primarily in connection with the sale of standing timber. The procedures described involve the use of tariff tables which have been used for this purpose by the Forestry Commission since 1956. The tariff system of measurement has subsequently proved efficient and reliable, […]
Measurement of timber is required for several purposes. The most obvious of these, perhaps, is the need to quantify forest produce for sale. Measurement of timber is also required in management, notably for planning purposes and for control of resources. This publication is intended to provide the information necessary to meet the needs of measurement […]
This Field Book describes the top diameter method for estimating the volume of logs which is usually confined to softwood sawlogs. This method is less time consuming and so cheaper than the more traditional mid-diameter method and is best suited to batches of uniform length logs. The description of logs in terms of top diameter […]
Stem straightness is important in determining tree and log value. The ability to make an effective assessment before harvesting is useful for forest managers and practitioners to improve forecasting, planning, marketing and resource use. This Technical Note describes three methods for assessing stem straightness in standing trees: visual assessment, photogrammetric measurement and terrestrial lidar. It […]
Forest Research are the leading UK research organisation on the development of spatial analysis techniques for habitat networks and have an excellent track record of working with and delivering tailored habitat network analyses.
What are habitat networks, and why are they important?
Habitat networks are configurations of habitat that allows species to move and disperse through a landscape […]
Our research-focused chemical analysis laboratory provides soil, water, plant and foliage (leaf) testing to support a wide range of agricultural and forest-related activities.
Environmental monitoring
Plant, soil and water analyses are key to any environmental or site monitoring exercise, whether for regulatory or research purposes. We can provide a basic laboratory testing service, or work with you […]
