Tree Injection for Timber Stand Improvement

Undesirable vegetation can drastically reduce commercial production in forests. Pine stands containing 20–30 percent hardwood basal area can suffer up to a 50 percent reduction in pine volume growth, or be so thick that sunlight does not reach the forest floor at levels sufficient to maintain vegetation needed by wildlife. Conversely, hardwood stands may contain species undesirable for landowner objectives. In either case, if undesirable stems become large enough, they can no longer be easily controlled through prescribed burning or herbicide applications appropriate for low-growing vegetation. Millions of acres of Mississippi’s commercial forestland could benefit from control of these larger undesirable stems.
