Quick Answer
Axis deer are considered an exotic species in Hawaii because they were introduced to the islands as an attempt to establish a game reserve. They were first released on the island of Kauai in the 1950s and have since spread to other islands including Oahu, Maui, and the Big Island.
History of Introduction
Axis deer (Axis axis) were introduced to Hawaii by hunting enthusiast and game reserve owner, Charles Hunter. Initially, Hunter released eight axis deer on Kauai in 1959, with the intention of creating a game reserve for hunting and ecotourism purposes. This action was meant to establish a self-sustaining population of axis deer in Hawaii, but unfortunately, the deer have since established themselves as an invasive species, causing significant ecological harm to native Hawaiian ecosystems.
Ecological Impact
The axis deer population in Hawaii has grown exponentially since its introduction, with estimates suggesting that there are now over 100,000 axis deer on the islands. This rapid population growth has led to widespread habitat destruction and degradation, particularly in areas with high concentrations of native vegetation. In addition, the deer’s diet consists mainly of native plants, which can cause significant declines in plant populations and alter the structure and composition of native ecosystems.
Challenges to Management
Efforts to control the axis deer population have been hindered by the deer’s adaptability and ability to evade human detection. The deer’s population size and distribution are estimated using techniques such as camera traps and aerial surveys. However, management efforts face significant challenges, including limited funding and the need for effective population control measures. Effective population control measures include hunting, culling, and habitat modification.
