| Popis: | Performance of 1-0 bareroot green ash (Fraxinus pennsylvanica Marsh.), sycamore (Platanus occidentalis L), and baldcypress (Taxodium distichum L., Rich.) planted on drained beaver (Castor canadensis) impoundments in southwest Tennessee was promising at the end of three growing season.First-year survival was significantly increased in plots where swamp cut grass (Leersia oryzoides) was controlled; however, effective grass control opened the site to aggressive invasion by broadleaf herbaceous vegetation. No treatment effect was noted for survival or growth of seedlings by the end of the third year. Containerized seedlings of swamp white oak (Quercus michauxii Nutt.) and willow oak (Quercus phellos L) failed due to poorly developed planting stock. Natural regeneration 3 years after drainage was poor, averaging 333 boxelder (Acer negundo L.), 42 black willow(Salix nigra Marsh), and 21 cherrybark oak (Quercus falcata var. pagodaefolia Ell.) stems/ac. Continued beaver control was necessary to prevent recolonization of plantation sites. South. J. Appl. For. 16(3):151-155. |
