Abstract
A new type of protective screen for seed spots has attracted the attention of foresters on the Pacific coast. This screen is cylindrical in form, 4 inches long, about 1 inch in diameter, and is formed from 8-mesh hardware cloth. Foresters have named this protective device a "K-screen".
K-screens appeal to the forester because they are relatively cheap, can be pre-loaded with seed and germinating medium before being transported to the field, can be placed quickly, and may not need to be removed from the seed spot. To protect the seed from rodents, the tops of the screens are pinched partially closed. It is anticipated that established seedlings will grow through the pinched tops without deformation, and that the screens will eventually decompose or be pushed open by the growing tree.
