Planting A Tree Can: Planting a tree can be simple - and is, for example, in forestry plantations where tens of thousands of trees are planted. Holes are made, the trees inserted and the soil made firm. But care and attention improve the chances of success with garden trees. "Basin planting", with the tree placed in a little hollow, will encourage moisture flow in dry areas as, in contrast, "mound planting", with the tree raised slightly above ground level, helps where the ground is very wet.
Among good shade trees are:—sugar maple; red maple, Pin oak, moraine locust, sweetgum, ginkgo, green ash, Chinese scholar tree, yellowood, black tupelo (sourgum), willow oak, laurel oak, south¬ern magnolia, camphor tree, and Amur cork tree. Kinds to avoid, although special circumstances may make planting any of them desirable, are poplars, willows, tree of heaven, box elder and Siberian elm.See Also Growing Tree:Used to reinforce the existing root system of a growing tree when the current root system is weak. A number of seedlings or rooted cuttings are planted around the tree and then grafted onto the stem, usually being held in place by nailing. Bridge grafting is a means of connecting an in¬tact root and stem when the connection between them has been seriously damaged. Scions, beveled at each end, are inserted above and below the girdled area to create a living bridge. Bracing the framework of a tree is accomplished by graft¬ing. Young branches are twisted around each other to encourage the formation of a natural graft, which serves as a brace.
The ground sloths were once classified as a separate group from the two living tree sloths, but it is now thought that each of the tree sloths represents a line of previously ground-dwelling sloths. The complex adaptive characteristics of the feet have led to a theory that sloths were tree-dwellers in their very early history in South America, later be¬came ground-dwelling forms, and then returned to the trees. It is also possible that there have always been tree-dwelling forms.
On The Other Hand See Crotch Of Tree:Reproduction: May be 2 litters a year; 1-6 young; born in bulky nest made of twigs and leaves, placed in crotch of tree or in hollow of rotted tree trunk; born through summer months
Life span: Recorded at 15 years
Economic position: Excellent agent in reforestation
CLIMBING SPACE: Pet should be given plenty of freedom in room. In one corner of room place large, heavy, branching limb that reaches from Floor to ceiling; this is an excellent playground for pet and gives it sufficient exercise.
NESTING BOX: In wild, nest is made in tree holes or is constructed of twigs and leaves placed in crotch of tree. In captivity, usually nests on shelf in cage. Place wooden box 12" X 12" X 6", with one end open, on shelf (see squirrel cage diagram, Part IV). If pet does not take to box, remove it. Nesting materials—Supply dry grasses, thin, loose bark, lichen-covered twigs, and bits of kapok; pet mixes these and constructs own nest. Supply fresh materials several times yearly.
