Benefits of Trees

 

Trees provide a wealth of useful products. People use trees and their products for:

  • Construction – huts and houses, fences
  • Food – fruits, roots and bark, macimbi and honey
  • Medical purposes
  • Fodder for livestock
  • Tools – farming implements, handles, traditional plates, spoons, pestle and mortar, furniture
  • Rope
  • Energy – fuel wood especially for people with no electricity or other fuel sources

Trees have important functions in the ecosystem

  • Trees produce oxygen and reduce carbon dioxide
  • Trees enhance soil conservation – the leaves reduce the impact of the large erosive raindrops
  • Leaves and litter enhance soil fertility by forming humus
  • Roots bind soil to reduce soil erosion, hence increasing infiltration of water into the ground, which then finds its way to springs, rivers, wells and boreholes

What are values and benefits of conserving trees?

  • Maintaining trees and forests enhances and improves the scenic value of the landscape
  • Such landscapes attract wild animals, which provide marketable products such as photographic and hiking safaris, trophy hunting safaris, skins and game meat
  • Trees increase the value of land for eco-tourism and related enterprises
  • Trees sustain and increase wild fruit yields for the farmer to harvest, process and market
  • Trees provide wild edible worms; madora/macimbi, and beetles; harurwa – which people can harvest, process and market
  • They provide shelter and windbreaks for crops and homesteads
  • Woodlands promote cloud formation and hence rain
  • They reduce the chances and incidence of flooding
  • They provide the ingredients for many traditional medicines

What is the cost of indiscriminate tree cutting?

  • Degradation of land by erosion, leads to loss of the fertile topsoil, resulting in reduced crop yields and loss of grazing as seen in Seke, Chiweshe, Zvimba and Ntabazinduna
  • Increased flooding and negative impacts associated therewith
  • Reduced amount of rainfall
  • Gullies and denuded bad lands
  • Walking long distances for firewood collection and other forest products, which leaves less time for other productive activities
  • Losing hard earned cash to buy forest products such as firewood and medicines that are otherwise available from the local woodlands

 

 

 

 

 

 

 

 

 

 

 

 

Destructive woodland practices

The following practices damage or destroy forests and trees, reducing the sustainability of economic benefits derived from woodlands:

  • Continued tree cutting and selling of timber, by the roadside, by ferrying to towns and growth centres, or for tobacco curing
  • Cutting of large trees or branches to harvest fruit, Madora, and other edible insects
  • Fires
  • Woodcraft
  • Burning down trees to access honey, which kills bees and destroys trees
  • Cutting down trees in grazing areas, mountains and land not required for cropping
  • Destructive medical collection from trees through complete removal of the bark around the stem
  • Cutting of tap root or main roots of the tree for medical uses

Sustainable woodland management practices

Existing woodland resources should be managed sustainably, and lost trees should be replaced by planting plenty of indigenous trees.

This can be done by:

  • Collecting seeds, establishing nurseries and transplanting young trees
  • Taking cuttings and planting young mature stems
  • Coppicing –coppices are shoots that grow from the stump after a tree has been cut, then grow into a new tree
  • Planting truncheons – larger cuttings usually planted to make living fences
  • Planting stumps – short stumps with taproots are planted especially in very dry areas.

 

 

 

 

 

 

Caring for young trees

Young trees require much attention and care especially in their first year. Take care of them by:

  • Tending them – water adequately and remove weed
  • Pruning them – to encourage the tree to branch higher up, thus saving the shoots and stems from livestock
  • Pollarding them – cutting off the top of a tree, out of the reach of livestock, which produces more shoots and stems above the cut
  • Removing excess shoots growing from ground level, to promote thick healthy stems
  • Controlling pests – ensuring trees are not damaged or destroyed by pests

"Trees are life"

This might sound too far fetched, but one uses trees and their products right from birth. Remember the cough and sore remedies. We also use trees when we leave this earth – remember the coffins and bonfires during the funerals. Trees are life and we need to conserve them. Schools are therefore encouraged to embark on the establishment of tree nurseries.
