Black Swamp Creek Hymenachne Pest Management
Case study type
This project implemented a long-term pest management plan with the objective of eradicating hymenachne and controlling other pest plants such as GRT and groundsel bush.
Hymenachne was scattered over 2km and five properties, with the main infestation within Council property.
Ongoing control has resulted in reduced infestation in the upper and lower reaches, from scattered low density to occasional and scattered, and a 50% reduction of hymenachne within the Council property site.
This project implemented a long-term pest management plan with the objective of eradicating hymenachne and controlling other pest plants such as GRT and groundsel bush at Black Swamp Creek.
The extended wet season expands infestation temporarily. Grazing appears to assist in reducing infestation if undertaken before seed set. Control over several years is required to reach eradication and monitoring status.
