Habitat Management

In the Park, different types of habitats are created to meet the needs of wildlife. In order to maintain the quality of the habitats created and to meet the need of wildlife living there, different types of management measures for each of the habitat type are developed and implemented. The habitat management works at the Park can be divided into three aspects, namely water, vegetation and wildlife.

 

Vegetation Management

Vegetation Management

The vegetation at the Park is maintained for amenity and conservation purposes. While the visitation area is managed for the enjoyment of visitors, the conservation zone in the Park is maintained to its natural look. Weeds, overgrown and invasive plant species are removed while native plants are planted in a way to increase species diversity and attract wildlife. Examples include: larval food plants and nectar plants for butterflies and tall emergent plants along water edges to allow dragonfly nymphs to emerge.

 

Water Management

Water Management

Water is crucial to the health of wetland in the Park. In order to ensure the quality of water in the freshwater marshes is good, the Park is regularly monitoring the quality of water taken from the storm water run-off from Tin Shui Wai. The Park also manages the water level at different water bodies by controlling sluice gates and pumps. This is crucial to the growth of aquatic plants. During winter, the water level in freshwater marshes is lowered to provide more areas at water edge for migratory birds wintering at the Park.

Invasive alien species including Mile-a-minute Weed (Mikania micrantha), Water Hyacinth (Eichhornia crassipes), Tilapia (Oreochromis spp.), Apple Snail (Pomacea canaliculata) and Red Imported Fire Ant (Solenopsis invicta) are removed regularly to control their populations and distributions in Wetland Park.

Artificial Nests

Since 2003, the Park has installed artificial nest boxes of different sizes for forest birds, i.e. owls, magpie robin, etc. Camouflaged bat boxes are also installed to provide artificial roosts for bats. To avoid human disturbance, these nest boxes are usually placed in woodlands away from visitors.
