Even if nearly all of the world’s wooded area ecosystems are ruled by means of uneven-sized multi-species stands, wooded area administration perform and conception has curious about the advance of plantation monocultures to maximise the availability of trees at cost-effective. Societal expectancies are altering, even though, and uneven-aged multi-species ecosystems, selectively controlled as non-stop conceal Forestry (CCF), are frequently believed to be more desirable to monocultures in addressing quite a lot of expectancies. This booklet offers methods  that are proper to CCF administration and making plans: analysing woodland constructions, silvicultural and making plans, financial evaluate, in keeping with examples in Europe, Asia, Africa and North and South the United States.

1 Assessment Traditionally, a forest ecosystem is characterised by area-based attributes (basal area, biomass, number of trees per hectare), mean values and distributions (diameters), and relationships (DBH-height regression). These classical attributes of a forest ecosystem are usually assessed in the field by sampling in field plots of specified shape and size (Kleinn et al. 2010). Fixed area plots of circular, square or rectangular shape (Fig. 9) and sample points using the angle count method are most common.

They did not use a reference point but a reference tree, thus allowing cohort-specific structural analysis. Cohort-specific structure refers to the specific structure in the vicinity of a cohort of reference trees, for example the structure in the vicinity of a given species, or in the vicinity of very large trees. They also considered more than two neighbors, thus extending the neighborhood range. Finally, they proposed that the angles should not be measured exactly, which would be time consuming during field assessment, but classified.
