Estimating tree and stand volume in mature plantations is time consuming, involving much manpower and equipment; however, several sampling and volume-prediction techniques are available. This study showed that a well-constructed, volume-equation method yields estimates comparable to those of the ...

The biological processes that affect seed production in natural southern pine are documented, and information that will allow foresters to manipulate stands in a manner to improve and predict seed production is provided. As a result, natural regeneration should become a more reliable technique.
