Red oak, black walnut, and black walnut with autumn olive, a “nitrogen-fixing” shrub, were planted on graded, compacted cast overburden (topsoil-substitute) minesoil with a dense ground cover consisting chiefly of tall fescue grass. Compaction was mitigated by ripping on half the plots. Year 1 establishment of all species was equal or lower on the graded versus graded/ripped plots. After 12 years red oak survival was 9% where unripped versus 61% where ripped. Black walnut survival was respectively 41% and 74%. Red oak 12-year heights were 2.2 m on the graded and 4.5 m on the graded/ripped plots. Black walnut heights averaged 2.6 m and 5.5 m respectively. Diameter breast height similarly was greater with ripping for the oak and walnut. Deer damage was substantially greater on the red oak than on the black walnut trees. Black walnut was interplanted a year later with autumn olive on unripped and ripped graded minesoils. After 12 years survival of black walnut interplanted with autumn olive was 42% where unripped and 85% in two ripped plots. Corresponding heights averaged 3.8 m where graded and 5.7 to 6.4 m where graded/ripped. |
