Riparian fencing to control stock/feral animal access
Fencing to exclude or control the access of domestic stock and feral animals to the river channel and adjoining riparian areas or other wetland systems can be an effective management technique. A range of fencing materials and methods (e.g. multi-strand, mesh, drop down, electric, virtual) can be used subject to the target animals for exclusion, the scale of the site, the adjoining land uses and the requirements of native animals to access the site.
Unregulated access of domestic stock (e.g. cattle, sheep and horses) and feral animals (e.g. pigs, goats, deer) to the riparian area and channel can degrade vegetation, limit regeneration and revegetation, cause soil compaction, cause riverbank erosion, introduce weeds and add additional nutrients (leading to poorer water quality) and pathogens. For example, calves shed 57 million oocysts per day on average in their manure which may include cryptosporidium. This number can be compared to a beef cow, which sheds on average 2,400 or a dairy cow at around 80,000 oocysts per day (Juvenile stock in waterways).
Fencing may involve total exclusion of target animals or controlled seasonal access of grazing stock to the riparian zone. Controlled access facilitates beneficial outcomes such as grazing of palatable weeds and the control of dry season fire fuel loads. Managed animals predominantly include domestic grazing stock (e.g. cattle, sheep and horses). Feral animals can include cattle, horses, donkeys, pigs, goats, deer, feral predators such as foxes and invasive species such as cane toads.
