Early Survival of Loblolly Plantings on Eroded Lands
Studies in north Mississippi during 1949-58 show that first-year survival is a good indicator of the success attained in establishing loblolly pine on a wide range of eroded sites. First-, second-, and third-year survival were recorded for 25,000 seedlings in 47 study installations on barren gullies with exposed compact sandy-clay Coastal Plain parent materials; in abandoned fields with a herbaceous cover, mainly of broomsedge; and under deadened hardwoods. As table 1 indicates, losses during the first year averaged 19 percent. Second- and third-year losses combined averaged 6 percent and ranged from 2 percent on gullies to 10 percent for conversion plantings. The data in the table are from both wet and dry years. Site averages are not strictly comparable because all sites were not planted every year.
