The first successful milky stork reintroduction was carried out in Kuala Selangor Nature Park in 1998 with the release of 10 captive-bred individuals here. Matang Mangrove Forest in Malaysia has been a popular candidate reintroduction site because this area is considered a suitable milky stork habitat in terms of shelter, breeding and feeding grounds; and there are apparently minimal threats from predators and parasites. The area is also protected and systematically managed, and raw materials are sustainably harvested here. However, captive individuals released into their natural habitat face new potential threats such as susceptibility to disease, lack of ability to hunt for food and defend territory, and lack of ability to effectively detect and evade potential predators. These released individuals may also harbour disease and parasites that could harm wild populations.
