A discussion of regeneration methods would be covered by authors handling silvicultural systems in bottomland hardwood forests. Introduction - Overview of information to be presented in this section Natural Regeneration Important definitions: regeneration reproduction advance reproduction regeneration pool reproduction sources seedlings seedling sprouts stump sprouts root sprouts (Figure illustrating sources) Reliability of natural reproduction sources for key species (Table - list of species by probability of seeding, seedling sprouting, stump sprouting, and root sprouting) Techniques to follow seed development and assess seed crops (Figure - fruit of various hardwood species, e.g. 1 and 2 year old oak fruit, ash fruit, sweetgum fruit, sugarberry fruit) Seed dispersal mechanisms for key species (Table of dispersal mechanisms for key species) Longevity of seed in the seed bank (Table of seed longevity for key species) Germinative requirements for seed (Table of germinative requirements for key species) Longevity and development of reproduction in the regeneration pool (Table of seedling shade tolerance for key species) (Table of seedling flood tolerance for key species) Practices to improve the understory microenvironment or morphology of reproduction to improve establishment, and invigorate growth and development of advance reproduction partial cutting midstory control understory weed control soil scarification seedling clipping Artificial Regeneration Important definitions direct seeding underplanting Direct Seeding Collecting seed Viability testing and handling Seed storage. Site preparation Timing, depth, and density of sowing seed Hand sowing Machine sowing (Table of # seed per pound for key species) Potential direct seeding problems seed quality species selection competition soil condition seed predators Planting Obtaining seedlings Judging seedling condition and handling Seedling storage Site preparation Timing, density, and procedure of planting seedlings Hand planting Machine planting Potential planting problems seedling quality planting quality species selection competition seedling herbivory Underplanting Stand and site preparation partial cutting midstory injection understory competition control Seedling establishment spacing post-planting competition control Seedling release Potential problems Regeneration Evaluation Tools and Decision Models revised Johnson model by Hart et al.
