APARIMA COMMUNITY ENVIRONMENT (ACE) PROJECT
Case study #2
Dirke and Petra Dietsche
Waimatuku Catchment
CASE STUDY
The Dietsche’s operate a large dairy property in the upper Waimatuku catchment, bordering the
Bayswater Bog in the Drummond area. The topography of the property has areas of rolling hill on an
upper terrace before dropping down to flatter land adjacent to the Bayswater Bog.
Dirk was interested in installing some sediment traps on his property and sought advice from
Environment Southland to determine the best locations for sediment traps on the property. A number
of sediment traps were constructed in three different areas of the property, all utilising small gully
and swale areas. Some of these areas were being used as farm forestry blocks, with sediment traps
being installed after the trees had been harvested.
Due to the locations of each of these sites, they each have their own separate catchment areas
ranging from 21-28ha in size.
Thriving Southland is a community-led group with a vision to create a prosperous Southland, healthy people, healthy environment from the mountains to the sea.
