However, total failure usually results from a combination of factors including poor site preparation, poor seedling quality, poor seedling handling practices, lack of competition control, improper planting, or planting the wrong species of trees on a given site. Overstocked and overmature stands are most susceptible. In these stands, mortality is usually random with scattered, individual trees being affected. Although drought contributes to stress, often insects, disease, or wildfire are the ultimate cause of death. There are few immediate solutions to prevent drought damage in timber crops.
Irrigation is impractical or impossible except in very small, newly established stands.
The best defense against drought damage is to follow recommended guidelines for regeneration and stand management. Ask county foresters, extension foresters, industry or consultant foresters to assist you in decisions related to forest management. Stand Establishment Site Preparation. Most commercially valuable species require full or partial sunlight for seed germination, establishment, and early growth. Broadleaf weeds, grasses, noncommercial trees, and brush compete with seedlings for limited moisture, food, and light.
