Habitat Management

Different types of habitats are present in the Park to meet the needs of wildlife. To maintain the quality of these habitats, we have devised and implemented corresponding management measures for each of the habitat types which can broadly be divided into three aspects, namely vegetation, water and wildlife.

Vegetation Management

The vegetation in the Park is managed for both scenic and conservation purposes. While weedy, overgrown and invasive alien plants (e.g. Mile-a-minute Weed (Mikania micrantha) and Water Hyacinth (Eichhornia crassipes)) are removed, a number of native plants are planted to attract and support a vast array of wildlife, enhancing biodiversity. For example, larval food plants and nectar plants at the Butterfly Garden for butterflies, and emergent plants at the Succession Walk to allow dragonfly nymphs to leave the water and emerge into adults.

Water Management

Water is crucial to wetlands. Natural precipitation is the main water source of the Park. The water levels of different water bodies are controlled by sluice gates and pumps, influencing the growth and distribution of aquatic plants, and providing suitable feeding grounds for waterbirds.

Moreover, the reedbed filters out suspended solids and uptakes excessive nutrients in the water during circulation within the Park. The water quality in the Park is also monitored regularly.

Wildlife Management

Control of Alien Species

Invasive Alien Species Control

Apart from invasive alien plants removal in vegetation management, invasive alien animals including Tilapia (Oreochromis spp.), Apple Snail (Pomacea canaliculata) and Red Imported Fire Ant (Solenopsis invicta) are also removed regularly to control their abundances and distributions in the Park.

Artificial Nests

Artificial Nest Box

The Park has installed artificial nest boxes of different designs and sizes for birds (e.g. owls) and bats to breed and roost respectively. To avoid human disturbance, these nest boxes are usually placed in woodlands away from visitors.
