Three large-seeded tree species, northern red oak (Quercus rubra), pin oak (Quercus palustris), and bur oak (Quercus macrocarpa) and one small-seeded species Paulownia (Paulownia tomentosa), were spot-seeded and European alder (Alnus glutinosa) was broadcast-seeded on eastern Kentucky surface mine spoil. Treatments included four mulches-hydromulch, shredded bark, shredded bark and poultry manure, and Real Earth (composted municipal waste and sewage sludge), two fertilizer treatments and two rates of grass/legume ground cover seed sown in competition with the tree species. Germination, growth and survival were evaluated after the first growing season. All three oak species germinated and grew well while both small-seeded species failed to become established from seed. Germination was affected by aspect, mulching, fertilizing and competition. Spoil moisture appeared to be indirectly responsible for most of the responses. The variables tested had little effect on the first years growth of the species tested.
