The Waterway And Wild Trout Fishery - 1490 Words

The Motueka is a nationally important waterway and wild trout fishery. The river drains and area of 2076km2 of mountainous and hilly land that is located about 40 km west of Nelson, South Island, New Zealand. The catchment elevation ranges from sea level up to around 1600 to 1800 meters. The river rises in the southeast of the catchment and flows north into Tasman Bay about 116 kilometers. The main stem of the Motueka River rises in the Red Hills and flows north to the sea. The Motueka River is joined from a succession of small and medium-size tributaries draining hilly land underlain by Moutere gravels and some of much larger tributaries originating in a complex combination of sedimentary and igneous rocks which form the mountainous terrain of the Arthur Range on the western boundary of the catchment. The Motueka Catchment is a large rural. It delivers up to 90% of the freshwater to a large and productive coastal bay. The whole catchment was originally covered in beech forests and podcarp. The major productive land uses are content 25% of exotic forest, 35% of native plants, 19% of smaller areas of pastoral grassland, 12% scrub and 7% tussock grasslands and increasing dairying. More than half of the catchment has been cleared with in exotic, plantation forestry and few in dryland pasture or cropland. The Motueka River flow generation is controlled by rainfall distribution and geology. The largest contributors to river flow in the lower Motueka are the west and southeastShow MoreRelatedEssay on Silent Spring - Rachel Carson30092 Words   |  121 Pagesembarked on her long career as a civil servant, an endeavor that would occupy her for the next decade and a half and the crucible out of which would come the influential nature writing of her later life.
