Critical Source Area Management

Critical Source Areas are areas that collect surface water and can transport nutrients to waterways or groundwater. Critical Source Areas (CSA's) are marked on the Winter Grazing Plans for each paddock. All paddocks are within either the Maerewhenua or Waitaki river catchments (or Bushy Creek/Sheepwash Creek tributary) which are significant rivers for Ngai Tahu and these are the strategies to mitigate risk to the river values.

Loch Lomond Slopes

Maximum slope grazed is 30 degrees.

Loch Lomond Soils

Note that paddocks west of the Maerewhenua River are listed on Environment Canterbury  Soil Layers. The remainder are on SMap as viewed above.

Grants Rd Paddock Plans

The CSA's are all normally dry and consist of swales. All are planted in crop because they have grass buffers downstream. The smallest grass buffer is 732m from the paddock to the Maerewhenua River. There are subsurface drains but they empty into the paddocks and the nearest waterway to a drain exit is across 996m of grass so rather than a risk of conveying contaminants to water they are considered a mitigation to reduce pugging and pooling.

The flat paddock at the bottom of Stock Road is in close proximity to the creek which is a risk and has a CSA consisting of a swale through the paddock to the North East corner. To manage the risk there is a 45m grass buffer within the paddock consisting of the last portion of the CSA before the fence which has not been planted in crop, and another 42m from the paddock to the creek. There are points where the paddock is closer to the creek but a raised plough line has formed a ridge along the fenceline preventing contaminants exiting the paddock - contaminants will run into the interior of the paddock to the CSA and through the buffer instead.
