The Mauritius olive white-eye is protected by law, and part of its range occurs within the Black River National Park. There are also plans to purchase habitat around Bassin Blanc (2). In 2005, a species recovery programme was initiated by the Mauritian Wildlife Foundation, with the aim of increasing knowledge of the Mauritius olive white-eye and its threats, and to investigate management techniques. Since then, an intensive management plan has been applied to the species, involving monitoring of the wild population, undertaking predator control at nest sites, rescue and harvest of wild nests, artificial incubation, and hand-rearing of offspring. However, it is thought that effective habitat management and releases onto predator-free islets are more viable options than captive breeding (2) (6).
On the mainland of Mauritius, rehabilitation of the native vegetation is underway in order to improve food sources for native birds, and there are plans to develop Conservation Management Areas with high densities of nectar-producing plants and where predators are strictly controlled. Between 2006 and 2007, a number of Mauritius olive white-eyes were released onto the predator-free, restored islet of Ile aux Aigrettes. This new population has been closely monitored and has been provided with supplementary food, and in 2008 at least two breeding pairs were recorded (2) (6). Other recommendations include studies into the species’ ecology and habitat requirements, providing artificial nectar feeders, and measures to try and increase breeding success (2) (3) (7). It has been found that nest predation is lower in areas dominated by introduced conifers such as Cryptomeria and Pinus (3) (8) (9), suggesting that the role of non-invasive exotic trees in the survival of the Mauritius olive-white eye should be further investigated (3) (9).
