Trees may be sold either standing or by sale at delivery price. In a sale at delivery price, the forest owner is responsible for harvesting the trees, while in a standing sale it is the buyer’s responsibility. In a sale at delivery price, the price of the wood is called the delivery price, in a standing sale it is called the stumpage price, because the tree is sold while still attached to its stump. The delivery price is higher than the stumpage price. The deed of sale made in connection of a standing sale is called a felling agreement, because in fact the forest owner gives the timber buyer the right to fell and use or sell the trees defined in the agreement, against the price agreed.
