Mangrove Development Office is located at 11 Moo1 in the District of Sai Dang in the KlongLumEing-La Oon National Park. The arboretum was a demonstration project where its tree planting began in March 1983. Later on in 1985 it was transformed into a mangrove arboretum, aiming to facilitate educational excursions. It has a botanical path of approximately 1,500 meters.There are more than 25 mangrove plant types out of the world’s 68 including the Tabun Dum Yak which is over 200 years old. This particular arboretum is considered to be the most pristine mangrove in Thailand.Through the concrete path are information signs spread across the route, each explaining about tropical mangroves in Thailand and their unique plants. Moreover, these informative signs also explain types of wood found in rainforests. Other than exploring an untouched mangrove, visitors can also enjoy seeing wild monkeys, a large variety of marine life; prawns, sea shells, fish and crabs as well as otters and exotic lizards. There are also many types of birds here such as hawks, cormorants and fish eating birds.The office has recently built a bridge for visitors to experience nature at a closer view. Part of the bridge which crosses a canal is 38 meters long and continues for around 200 meters. There are little gazebos and a canopy watch tower for relaxation.The mangrove arboretum also offers an exhibition near the attraction’s viewpoint. It showcases unique flower and plant species for people who are interested.
