Show H EFFECT OF GRAZING H ON TIMBER PRODUCTION H One Object of National Forests is H to So Harvest Forage Crop as H to Preserve Young Trees. I. Ogden, January 7-One of the chief H objects of the creation of national M Forests was to insure a continuous H supply of timber. Accordingly where H timber production is young it is es- M sential to so harvest the forage crop M as to preserve and foster the young ' M forest growth. Extensive studies have H been conducted at the Great Basin Ex- H periment Station and elsewhere to . B accomplish this end. H As a whole, injury to tree reproduc- : m tion by grazing regardless of the class H of stock, varies with the intensity of Hh the cropping. Where the range is ov- M ergrazed any class of stock is liable; H to inflict serious damage to young Hh seedling and saplings. In general WK sheep are more destructive to any H class of timber reproduction, cspe- H daily aspen, than cattle and horses. H Seedlings a year old or less are sub- H ject to much greater damage than old- H er plants. H of the utt osy.shrdletaorhiedlsntoian H Open quiet herding and the adop- H tion of the "bedding out" or "blanket H system" of handling sheep reduces the H injury to young tree growth. In the H case of cattle proie. distribution, H which may be bfOOgt about by jmli- H cious salting, herding, and the con- H Itruction of drift and division fen.e.s, H greatly reduces serious destruction to EH young timber growth.
