Is selective cutting bad?

Is selective cutting bad?

Selective logging is causing long-term changes to tropical forests in Africa by facilitating the growth of weeds and vines, which reduces plant diversity and diminishes carbon storage, reports a new paper published in the journal Ecological Research.

How does selective cutting improve biodiversity?

Selective cutting reduces crowding, encourages growth of younger trees, maintains an uneven-aged stand of tress of different species, and allows natural regeneration from surrounding trees.

Why is selective cutting a better way to log?

Selective logging is often considered a better alternative to clear cutting in which a large area of a forest is cut down, leaving little behind except wood debris and a deforested landscape. The ecological, social, and economic impacts drive a better understanding of efficient forest management techniques.

What are effects of cutting down trees?

The loss of trees and other vegetation can cause climate change, desertification, soil erosion, fewer crops, flooding, increased greenhouse gases in the atmosphere, and a host of problems for indigenous people.

Do trees grow back after clear-cutting?

Redwoods Regrow After Fires In the past 70 to 80 years, most fires in California’s coast redwood forests were prevented or suppressed.

How does clear-cutting affect human health?

But deforestation is having another worrisome effect: an increase in the spread of life-threatening diseases such as malaria and dengue fever. For a host of ecological reasons, the loss of forest can act as an incubator for insect-borne and other infectious diseases that afflict humans.

Why is cut clear?

The principal objective of clearcutting is to regenerate the forest with healthier trees, not to harvest timber. Timber harvesting is a secondary objective. Clearcutting is especially useful in regenerat- ing species of trees whose seedlings cannot thrive in the shade of a forest understory.

What animals are affected by clear cutting?

Four species of ducks, snakes, mice, several owls, nuthatches, chickadees, tree swallows, flying squirrels, bats, kestrels, wild bees, seven woodpecker species and many other animals and birds depend on such tree cavities. Current forest management regimes leave a few, largely useless, clumps of trees in clear cuts.
