Pest-exclusion fence

– Design Techniques:
– Animals can be excluded by a fence’s height, depth under the ground, and mesh size.
– Choose a construction material that cannot be climbed.
– Create a subsurface fencing element to prevent burrowing under the fence.
– Fences are designed with the target pest species in mind.
– Electric wire is often used to prevent animals from climbing over the fence.

– Examples:
– Orokonui Ecosanctuary in New Zealand has a 1.9m-high fence to exclude introduced mammals.
– Agricultural exclusion fences in central-western Queensland vary in height and design.
– Techniques to exclude crop-raiding elephants in Africa and Asia include electric fencing and fences of cacti.
– Exclusion fences in Australia are used at sanctuaries for captive breeding programs.
– Various techniques are used in different regions to exclude specific pest species.

– Use in Australia:
– Australia has utilized exclusion fencing since the 1860s.
– Barrier fences like the Dingo Fence and Rabbit-proof fence are well-known in Australia.
– Cluster fencing allows farmers to monitor and mitigate predation pressure.

– Exclusion fencing helps in monitoring Total Grazing Pressure (TGP) in agricultural settings.

– Use in New Zealand:
– Pest-exclusion fences are increasingly used for conservation of indigenous species.
– Predator-proof fences are located in various regions across New Zealand.
– Locations like Cape Brett and Zealandia use exclusion fencing for conservation efforts.
– Pest-exclusion fences are vital due to the ecological changes caused by introduced mammal species.
– Fences at sanctuaries like Orokonui Ecosanctuary help protect native wildlife.

– Use in Japan:
– Deer-proof fencing in Nagano Prefecture, Japan, aims to maintain plant diversity.
– The effectiveness of the fencing methods varies in conserving rare plants.
– Conservation fencing efforts in Japan focus on protecting specific plant species.
– Fencing techniques are used to prevent deer damage to vegetation.
– Japan uses exclusion fencing to safeguard plant biodiversity in conservation areas.
