PARK YOHO in Yuen Long's Kam Tin North is a large residential development, notable for its wetlands restoration and ongoing biodiversity conservation.
AEC, a member of the Aurecon Group, worked together with Sun Hung Kai Properties, to restore the existing wetlands into a rare, semi-natural, brackish marsh.
The ecological potential of the site was determined early in the development’s planning stage, identifying that wetlands restoration would provide important habitat for a variety of dragonflies, butterflies and birds over an area of more than 46,000 m2.
Before the development, the marshes had been gradually degrading, presenting a significant challenge for AEC in maintaining the complex hydrology of the site without increasing the risk of flooding to other basin users.
To achieve this balance, long-blocked waterways were restored to bring seawater and hillside streams running back to the area. The installation of a series of water control structures allows ongoing control of water levels using gravity flow. This process also permits the inundation of dryer parts of the marsh when required.
Restoration work and the re-introduction of reeds and mangroves gradually brought the marsh back to life. It is now home to more than 180 species of dragonflies, birds, and other wildlife – including the globally near-threatened Four-spot Midgets, Pallas’ Leaf Warblers, Great and Little Egrets, and Variegated Flutterers.
After designing the wetlands restoration, AEC developed a set of guidelines for its careful management for future generations. Aurecon’s role also continued for five years with ecological and wildlife monitoring, and overseeing additional conservation management activities.
This entailed regular surveys of wildlife species and habitat conditions. Where maintenance was required, Aurecon oversaw the changes required to water levels, and enhancement vegetation planting, to maintain the wetlands within the guidelines set for its management.
The original restoration and short-term monitoring now mean the wetlands is mostly self-sustaining with minimal maintenance required. It is now a flourishing wetland ecosystem, supporting a stable population of wild animals with natural biodiversity, and demonstrating the balance of residential development and nature.
