The floodplain habitats (Figure
9)are the prime choice for agriculture and cattle grazing
and it is apparent that the wetland grazers are engaged in
an unequal competition for resources. In 1996 the areas
cleared for agriculture amounted to some 21% of the wetlands.It
can be estimated that some 3,000km2 of potential
range for the wetland grazers still remains in the Caprivi.
However, with the exception of the protected areas, the impact
of human population pressure and livestock extends to almost
every part of the potential range(Figure
9 and figure
16). There are no protected areas in the Chobe-Zambezi
river system (Figure
13) which accounts for about half of the best wetland
grazer habitat in the Caprivi. Martin (2004) gives some crude
estimates of the wetland habitats in State Protected Areas
(Table 6). Salambala Conservancy may
provide the best hope for maintaining reedbuck, waterbuck,
lechwe and puku in this part of the Caprivi. Mudumu and Mamili
national parks and the 'Golden Triangle" (the Eastern core
area of the West Caprivi Game Reserve) provide protection
for a small part of the floodplain habitats in the Kwando-Linyanti
river system (Figure
14). The conservancies on the east bank of the Kwando
River may prove important in the future (Kwandu, Wuparo and
Mayuni) but, at the moment, livestock densities in the floodplain
habitats are relatively high. Mahango national park and the
'Buffalo Area' (the Western Core area of the Caprivi Game
Reserve) protect some of the floodplain habitat on the Kavango
river (Figure
15).

The actual area of floodplain habitat
within the Golden Triangle is less than 50%. However, an allowance
has been made for the area of floodplain at southern end of
the Kwando extending into the West Caprivi.
