Site tree (forestry)
Site tree refers to a type of tree used in forestry, which is used to classify the quality of growing conditions trees at a particular forest location. A site tree, is a single tree in a stand that gives a good representation of the average dominant or co-dominant tree in the stand. Site trees are used to calculate the site index of the site in reference to a particular tree species. A site tree should belong to the dominant or co-dominant overstory class. The total height of the tree and age measured at Diameter at breast height of a sample of site trees will be used to determine a site index, which will show how tall trees of different species can grow on that site in a set amount of time. Sometimes several years are added to the breast-height age to account for time grown below 4.5 feet (1.4 m).
