Near- ly 500 acres of loblolly pine and over 1, 000 acres of slash pine in plantations were 50 to 80 percent destroyed in one season. Where hogs have a choice, however, their order of preference is longleaf first, slash second, and then lob- lolly. Deer and rabbit repellents do not keep hogs away from pines. The only solution so far is to keep the hogs out of young pine stands, especially longleaf. Damage by cattle. --As a general rule, cattle do not browse pine foliage and have not been re- ported to cause much damage to pine reproduction. However, with increasing numbers of range cattle and the expanded reforestation program, specific instances of severe cattle grazing damage have been noted during recent years. Serious damage to pine seedlings has occurred mainly on over- grazed ranges, on spots where cattle concentrated, and in places or seasons in which forage was very sparse. Of course, the most critical damage is on newly planted or seeded areas, where the total number of seedlings is limited. Cattle grazing and trampling may kill small first- year seedlings and reduce the growth of older ones. The best solution is to anticipate or recognize and avoid the situ- ations where cattle damage is likely to occur. Here are some general rules to follow: - 26 -.
