Restoring China's Degraded Environment -
The Role of Natural Vegetation


Bare hills may need preliminary cover or herbs and then shrubs before trees can be introduced


Primates, bats and birds can be valuable seed dispersing agents for spreading forests


Forests protect water = life and prosperity

Mixed forest on poor rocky soils


Some tree-crops such as tea or rubber show very high rates of soil loss


Good grass cover can be very effective in water and soil conservation

Land scars account for a high proportion of local soil loss

Good mix of broadleaf and conifers, with multi-age structure

Farms on steep hills. Notice erosion gulleys on nearest field and old terraces lost under erosion


Good ground cover essential for soil protection

 

Programme Do Do Not Economic potential Investment required
Strengthening the protection of Forests and grasslands Close forests from fire, cutting, browsing by domestic animals, and hunting
Maintain natural species mix, age-staggered forests and high ground cover
Preserve natural agents of pollination and seed dispersal and wildlife that control pests
Develop representative protected areas
Develop fire protection plans

Convert natural grasslands to forest
Open up forests with too many roads
Reforest with monoculture plantations
Farming high altitude grassland

Employment of forest guards
Develop tourism with spin off industries
Grazing by non-browsers
Sustainable collection and rearing of medicinal plants

Tourism development

Training of local people for tourism and handicrafts work
Forest protection work

Restoring forest on degraded and bare hills

Zoning into 'ecological' versus 'sustainable production' forests, but ecological function needs should have precedence
Plant mixed forests of as near natural composition as possible
May have to follow seral succession phases to reach stable forest condition
Use rather than run counter to the local forces of nature. May have to provide soil and water to young trees until established
Close forests from cutting, burning, hunting and browsing
Develop forest connectivity with existing forests to allow biodiversity to recolonise new forests
Encourage dense ground cover

*Plant single-aged plantations of monocultures or exotic species
Clean undergrowth under plantations
Plant fire-prone plantations
*Plant species out of their natural zones (e.g. conifers in broadleaf zone)
(*In forests developed primarily for sustainable timber production, the guidelines may be relaxed.)
¡¤Develop sustainable forestry plots for timber, bamboo, mushrooms and medicinal plants
Employment of guards and foresters and nurserymen
Employment of fire protection staff
Some tourism potential
Some potential for animal husbandry e.g. pheasants
Costs of reforestation, aftercare and fire protection
Tourism development
Sustainable forest industries investments
Emergency treatment of bare land scars Augment physical engineering treatment with establishment of tree and especially ground vegetation
Plant with turf and bamboo clumps, not just seed or seedlings
Use unnecessary and potential weed-forming exotic species Employment of treatment staff and nurseries Costs for nurseries development and wages of associated work crews
Returning steep farmland to tree and grass cover Ensure that most forests are 'ecological' rather than 'economic'
Ecological forests should follow guidelines as for forest restoration
Study regional vegetation and natural succession sequences in planning reforestation
Economic tree crops should be diversified
Long duration compensation paid to farmers
Promote terracing on steep farms
Economic tree crops with poor ground cover
Free-ranging browsing animals
Convertion of slopes with good terracing or low natural soil loss
Plant whole regions under one dominant economic species
Production of fruits, timber, bamboo, mushrooms, medicinal plants and penned animals ¡¤Compensation programmes for farmers abandoning farmlands
Training for farmers to adapt to new industries
Invest in construction of terracing
Alternative employment Develop small-scale hydropower plants
Develop new local industries in townships to use cheap hydropower and absorb labour
Concentrate on large-scale projects which divert too much water and electricity from where it is urgently needed New employment opportunities
Cheap hydropower
Subsidized local energy to reduce pressure on forests for fuel
Investment costs of hydropower development
Road improvement to isolated townships
Investment in new industries
