A tree volume table for red pine by crown width and height
[Текст] / G.M. Bonnor ; Canada Department of Forestry. - Ottawa : Forest Research Branch, 1964. - 339-346 с. + tables. - (Forest Research Branch Contribution / Canada Department of Forestry ; 619). - Библиогр: P. 346. - 0-05 р.
Аннотация: A multiple regression analysis of parameters which can be measured or interpreted on aerial photographs showed that crown width and tree height exhibit a good correlation with diameter at breast height. A tree volume table based on the above relationship was constructed and tested with good results.
