    Uneven-aged silviculture using single-tree selection provides the landowner with periodic income from a continuous forest which has a varied canopy. Data were collected from 24 plots of a larger study to determine if site index, basal area, and maximum dbh affected volume and value of lumber from loblolly pine (Pinus taeda L.) trees in uneven-aged stands. Tree grades and lumber yield equations were used to determine the volume of lumber by grade for each tree. Market prices from May 1997 and May 1998 were used to estimate lumber value. Analysis of variance showed that study variables significantly affected lumber volume, lumber value/mbf, and stand value/ac. With 1997 prices, increases in site index and maximum dbh significantly increased lumber value/mbf, but only maximum dbh was significant with 1998 prices. Stand values ranged from $4,100 to $12,350/ac and were significantly higher for the higher site index, basal area, and maximum dbh.
