In the winter of 2015 Keystone Ecology were hired to restore the ecological integrity of part of the Halswell stream. The goal was to use the process of succession to convert the stream edges into native habitat again. This will not only help to stabilise the bank and increase biodiversity along the stream edge, but it could also improve the quality of the water in the stream. A selection of scrub species were chosen to be planted as height was a concern from a stream maintenance point of view. The plants were planted closer together to reduce the competition with weed species and reduce the need for extra chemical use.
