Timber Stand Improvement

Grapevines are fun to swing on, but hazardous to the health of your trees!

Timber Stand Improvement (TSI) is the management tool that can make sure you are growing valuable trees in your woods--those with good form and that meet the demands of the lumber industry.

TSI is not only good forestry;
it's good business!

Wild Grapevines
As children, many of us thrived on the adventure that could be created from a woodland full of grapevines to swing on. As adults, just remembering conjures up visits to our chiropractor!
Typically, most landowners have paid little attention to grapevines in their woodland. they may cut an occasional one to create a door wreath or other decoration. But by and large, most vines have been left to grow. With each periodic round of timber harvesting, the vines were ignored. After the harvest, they advance slowly, but persistently, in their quest to conquer the woodland.

As they spread, they begin to compete with trees for life-giving sunlight. In addition, their weight often disfigures the shape of crop trees. In heavy ice or snow storms, or even a strong wind, they can even cause tree tops to burst out. Their spread after a harvest can suppress the growth of new seedlings, having a long-term effect on future timber income.

To ensure diversity and balance in your woodland, some vines are necessary. Grapes come from grapevines and are a source of food for wildlife, particularly when other food sources are slim. Given this, it is normally wise to leave vines along the edge of the woodland, near creeks, and in permanent wildlife den trees. A variety of birds and animals will be grateful.

Landowners, take heed! Wild grapevines, if left uncontrolled, can harm the future productivity and return on your timber investment.

Cull Trees
Trees that are hollow, deformed, have large, "wolfy" tops and short trunks, or that have been damaged by time and weather and are showing signs of decay have very little market value at the time of a harvest. As a result, these trees are rarely cut when timber is sold (they are often not even worth the time it takes the purchaser to log them).

When these trees are left in a forest, they not only block sunlight and growing space from good crop trees with potential for higher future values, they can also reseed the area with poorer stock of trees. After generations of timber harvesting where these poor specimens were left behind, some woodlots may contain many, if not mostly, low value or cull trees.

But all is not lost. A good management program can usually turn most woodlots around. Through proper management practices, including a regimen of TSI for cull removal, a poor woodland can become a good investment once again.

FMS is experienced at the following TSI practices:

  • Deadening the "cull" trees and vines to release crop trees.
  • Thinning trees to a proper spacing for faster growth.
  • Completing forest openings to allow new seedlings to grow.
  • Pruning lower limbs on some species to create veneer.
Think of your timber as a savings account. TSI increases the growth rate of your timber, thus improving its rate of return (or interest rate). If you are serious about your capital investments, you seek the counsel of a professional advisor. If you are interested in maximizing your timber investment, you need an expert who knows how to plan and apply sound forestry.
