KEMMERER, H. 1979. Transplanting large trees. Grounds Maintenance 14(9): 22-24, 58.
The best way to have large trees in the landscape without waiting is to preserve existing trees during landscape development. Barring this, transplanting has merit. Trees of suitable size and quality can be purchased from nurseries, collected from the countryside or moved from another area within the grounds. There are several techniques for moving trees. A tree spade digs, lifts, transports, and replants the tree with a ball of earth in one operation. A more conventional approach is to dig the ball separately; burlapping, lifting, transporting, and replanting are completed as separate techniques. Another procedure is to grow the plant in a container (usually a box) in the nursery. When it is ready to be planted, it is transported to the site and placed in the hole; the box is removed and the hole filled.
NATIONAL ARBORIST ASSOCIATION. 1979. Safe chain saw use linked to technique, size. Weeds, Trees and Turf 18(8): 16-18.
Although chain saws have made the work of the arborist easier, improper use can result in personal injury. The potential for accidents seems to have increased in direct proportion to chain saws decreasing in weight. When using a chain saw, personal protective equipment must be worn. This includes work gloves, hard hat, and safety shoes. Ear protection should be worn if there will be prolonged exposure. A chain saw operator should never work alone. Only experienced personnel should use a chain saw aloft in a tree. Most chain saw accidents are a result of the saw kicking back. This can occur if the chain suddenly hits a solid object or takes too large a cut. The chain stops for an instant transferring the engine torque to the bar and engine. Proper hand holds and stance can prevent an accident from kickback. Each chain saw operator has a responsibility to himself to function safely. Carelessness can and will result in injury.
