Plantation forests

These scales of extent define the manner in which the ideas of extreme events are applicable to agriculture and forestry. Wind-throw is a small-scale process and the forest manager must grow and manage plantation forests which will survive extreme wind speeds at the spatial scale of his plantation. The question is, how rare must this extreme event be, before it may be discounted. The answer is likely to be dominated by economics and also the longevity of the plants with a 50 year harvesting interval, it seems clear that the return periods of extreme events up to 50 years (at least) are crucial.

Areas of plantation forests are not generally reported in developed countries. This estimates includes only China s plantations. Probably an underestimate. The estimate is for the US only, and similar values may apply in South America, Australia, and elsewhere. These values include loss of soil carbon resulting from cultivation of new lands they do not include accumulations of carbon that may have resulted from recent agricultural practices. 

Combustion tests were conducted for five biomass sources commonly available in New Zealand (Table 1). These fuels come from two species Pinus radiata and Eucalyptus nitens (E. nitens). Pinus radiata is an important commercial wood species in New Zealand accounting for 90% of the country s plantation forests. E. nitens is a purpose-grown plantation species which has been proven to be suitable as a short...

In studies of plantation forest species it is eommon praetiee to earry out surveys of wood density (and other properties) by means of 5 mm diameter inerement core samples at breast height. Often the unextraeted wood density (oven-dry wood substances plus the extraetives) is quoted in the literature.
