Simplified Tree Inventory Counting Frame
An open-end counting frame has been devised at the Saratoga State Tree Nursery. Heretofore, a similar frame has been used to define the sample area for taking the tree inventory in the nursery seedbeds. The older frame was completely enclosed, which meant that it had to be pushed down into the trees from the top to reach the ground. This was often difficult and consumed time to properly separate the tree stems that should go either in or out of the frame. The frames are made so that the inside length is the linear distance wanted; therefore, tree stems should fall in or out in relation to this inner edge. The new frame with an open end permits it to be applied from the side by sliding it through the seedlings at ground level (fig. 1). This works faster, and the sharper points differentiate the in and out tree stems automatically.
