uneven-aged

However, it is not as effective with uneven-aged stands.

Uneven-aged forests have three or more age classes represented.

The uneven-aged management style creates a forest with trees of various ages and sizes.

In general uneven-aged management helps ensure ground cover, which minimizes erosion.

Selective tree cutting and uneven-aged management are dominant in the beech forests.

Throughout winter and early spring, deer are generally restricted to uneven-aged old-growth forest below 1,500 ft (366 m) in elevation.

Even-aged silvicultural systems satisfy the reproduction and growth requirements of black oak better than the all-aged or uneven-aged selection system.

ProSilva recommends to use the uneven-aged forest system, in which the ages, and consequently sizes, of trees in a forest are different.

The third group is logged in an "uneven-aged" manner, with selective logging of trees throughout the three compartments in that group.

Uneven-aged management techniques where only certain trees are harvested, such as shelterwood systems, incur the same hourly costs while harvesting fewer trees per hour.

Presently Cal Poly SLO students are converting this unit to an uneven-aged stand.

Shelterwood systems may be implemented in even-aged or uneven-aged forest stands, but the desired result will always be a single, or even-aged cohort of trees.

Group selection - The group selection method is an uneven-aged regeneration method that can be used when mid-tolerant species regeneration is desired.

The Valencia Creek Forest presents interesting opportunities for study and evaluation in the areas of uneven-aged forest management of coastal Redwood forests.

Single-tree selection - The single-tree selection method is an uneven-aged regeneration method most suitable when shade tolerant species regeneration is desired.

Advantageous stand conditions for the spread of dwarf mistletoes include an uneven-aged stand structure with severely infected-hosts in dominant and codominant crown classes, species composition dominated by the primary host, and tree densities that are between 175 - 500 trees/ha.

Uneven-aged forests generally exhibit higher levels of vertical structure (key for many species of birds and mammals), have higher levels of carbon sequestration, and produce a more constant flow or market and non-market forest resources than even-aged forests.

"If there is a smart, multi-functional, low-cost, democratic strategy that can help to pull carbon out of the atmosphere, it's probably in this book: chinampas, step-harvest planting of trees (with six times the carbon density per acre), harnessing youth to the task, agroforestry, greening the desert, uneven-aged forest management, carbon farming, the soil food web, and more.
