We design, manage and assist in building Hawaii’s most effective predator proof fences. From the first fence at Kaena Point, we have worked to improve the design and decrease the cost of this technology. These fences are designed to be effective against all mammalian pests in Hawaii. They are tall enough (2m) to prevent animals from jumping over, have a hood to prevent them from climbing, mesh that is small enough (6mm) that even mice can’t squeeze through and has a skirt underground that prevents them from digging in. All of the materials are marine grade stainless steel to ensure longevity.
As of 2019, we have completed construction of four predator-proof fences: Kaena Point Natural Area Reserve in 2011 (pictured above right) Kilauea Point National Wildlife Refuge in 2014 (below left), James Campbell National Wildlife Refuge in 2016 (above left) and Honouliuli National Wildlife Refuge in 2018 (bottom right). We are currently in the permitting stage for four future fences. We work with local fencers using designs and materials revised for Hawaii's unique needs. We also provide fence line assessments and plans for those wanting to manage their own projects and complete implementation plans (see examples here for ungulate fencing, and here for predator fencing).
