The Bot estuary
(34°21' S;
19°5' E)
is situated just northwest of the coastal town of Hermanus in the Western Cape. The river is approximately 54 km long with a catchment area of 920 sq. km. Agriculture accounted for approximately 51% of the land-cover in the Bot catchment. This mainly comprised temporary commercial dryland agriculture, commercial forestry, permanent commercial irrigated agriculture, and improved grassland. Less than 1% of the Bot catchment was degraded, mainly comprising degraded shrubland and erosion scars. About 48% of the catchment was natural, mainly shrubland, bushland, grassland, and the waterbody of the Bot estuary. Urban development, mainly residential development and smallholdings accounted for approximately 1% of the catchment land-cover. This was mainly associated with the towns of Hawston near the coast, Botrivier in the middle catchment and Caledon in the upper catchment.
