Abstract
Tree growth is dependent on the availability of light, water, nutrients, CO2 and O2. Unless trees are overtopped by vegetation, CO2, O2 and sunlight are usually not limiting factors. However, intraspecific competition often results in a limited supply of water and nutrients to crop trees. Such competition can result in lower survival in new plantings and reduced growth in surviving stock.
Recent forest vegetation management research in combination with several older studies demonstrate large survival and growth gains in newly established forests. Such responses have resulted from reductions in woody or herbaceous or both types of competition. Only in recent years have researchers attempted to relate the effects of vegetation management to tree physiology. It appears that in most cases competition results in water being the limiting factor for tree survival and growth.
