Some green areas of the Hac Sa Reservoir Natural Park in Coloane will be optimised to create a butterfly-friendly garden aimed at enhancing biodiversity, according to a statement by the Municipal Affairs Bureau (IAM) on Thursday.
The bureau, which started the project on Thursday, expects it to be completed in July, the statement said, adding that the initiative follows the opening of Macau’s first butterfly-friendly garden in Seac Pai Van Park in March.
The statement noted that the new project will focus on improving ecological conditions by introducing a wider variety of plant species to support butterfly habitats, underlining that some of the park’s existing green areas offer only limited plant diversity, with signs of deterioration not conducive to biodiversity.
In order to address the issue, the bureau will introduce nuclear and host plants such as Lagerstroemia indica, Odontonema strictum, Asclepias curassavica, Jasminum sambac, Plumbago auriculata and Tibouchina granulosa.
These plants are expected to attract butterflies and create a natural corridor suitable for resting, foraging and breeding, the statement said, adding that the project will also allow visitors to observe butterflies up close, helping to raise public awareness of ecological conservation.
During the phase-by-phase project, parts of the green areas will be temporarily enclosed, with on-site signage providing information about the project, according to the statement.
The bureau advised visitors to follow safety instructions while using the park and called for public understanding regarding temporary inconvenience during the optimisation work, the statement noted.
