GOURITZ ESTUARY: Threats |
||||
|
|
A
fine balance should be maintained when planning future developments,
such as dams, which could result in a reduction of the regular
scouring of the river mouth by frequent smaller floods (Ref. 1). |
|
Invader plants such as Acacia
cyclops and Acacia saligna
threaten the environment.(Ref. 1). |
|
|
Other threats to the environment are wind erosion, overgrazing and over utilisation by animals and man, dune moles in cultivated lands, shortage of trace elements in soils, periodic flooding, brackish soils, poor quality, limited water for irrigation, low pH and nutrient values of soils. Wind erosion is aggravated by mineralization and salt deposition on agricultural lands and consequently results in the lack of vegetation cover (Ref. 14). |
