Wetland
Marshes or swamps
Saturated land linked to rivers
Importance of wetlands
Water purification-remove toxins effectively
Reducing climate-change- storehouses of carbon
Flood control-slow down force of water
Recreation and tourism-natural beauty and diversity
Reservoirs of biodiversity- provide habitat
Flora
Provide shade Bind soil together Purify water Regulate climate Provide wide range of products
Indegenous
Plants occur naturally
Place currently found
Not been assisted my man
Alien
Species doesn’t occur naturally in area
Introduced by man
Exotic plants
Invasive alien
Species reproduce and spread
Unassisted by man
Areas not wanted
Threat to nature conservation
Deforestation
Large scale removal of trees
Without replacing
Afforestation
Large scale planting of saplings
Where trees been removed
Forests
Damages roots Stunts growth Kills Strips waxy layers-protect from disease Weaken Less resistant to infection
Soils
Dissolves metals out of soil
Dangerous effect- PSL
Frogs and fish
High levels are toxic
Smaller and weaker
Provide less food to higher species
Buildings
Corrodes-marble, limestone, metal pipes,fittings
Human health
Carbon dioxide and sulphur dioxide
Increase heart and lung disease
