Often the entire tree may become stunted or distorted.
The western mistletoe is most common on the branches, where it produces "witches' broom." It frequently attacks the trunk as well, and boards cut from such trees are filled with long, radial holes which seriously damage or destroy the value of the timber affected. LOCALITY OF GROWTH The data available regarding the effect of the locality of growth upon the properties of wood are not sufficient to warrant definite conclusions.
The subject has, however, been kept in mind in many of the U.S.Forest Service timber tests and the following quotations are assembled from various reports: "In both the Cuban and longleaf pine the locality where grown appears to have but little influence on weight or strength, and there is no reason to believe that the longleaf pine from one State is better than that from any other, since such variations as are claimed can be found on any 40-acre lot of timber in any State.
But with loblolly and still more with shortleaf this seems not to be the case.
Being widely distributed over many localities different in soil and climate, the growth of the shortleaf pine seems materially influenced by location.
