There are successful coral transplant cases all over the world. We have launched a coral rebuilding project where 1,500 square metres of coral reefs can be rebuilt in 5 years by transplanting them in Hong Kong waters.
Both pipefish and seahorses have medicinal value, and they are now facing serious threats from overfishing. We discovered a few breeding and nursery grounds in a few inshore waters of Hong Kong. The long-term purpose of the survey is to establish a database that details the survival and fertility of the both the pipefish and seahorse.
Focusing on places of high ecological values and enclaves in Sai Kung and Lantau Island, most of which are not included in land planning, and are easily damaged by private developments. Our work helps to monitor the environmental changes of the ecological hotspots, and to provide data to support for the protection of these ecological hotspots.
Black Kite is the most common raptor in Hong Kong. Hong Kong is one of the few places in the world where you can see this bird close in the urban area. The rapid urban development of Hong Kong is threatening Black Kite's survival. We are organising secondary school students to regularly collect data on the species.
This is the first team of butterfly surveyors formed by the general public. The team visits many local butterfly hotspots to record the number of butterfly species and related ecological data. All data are uploaded to the Internet, so the public can monitor the conditions of the butterfly hotpots.
The 24 solar terms calendar was devised by the ancient Chinese to predict the weather and crop yields. Hence, we initiated the first butterfly ecology research according to solar terms. The ongoing research has been on the correlation between numbers of butterflies found and the solar terms.
Every year starting in October, Danaids from northern areas (such as Northern China) will migrate to the South to spend winter in a warmer area (including Hong Kong). Our survey has helped us to understand how their behavior changes when spending winter in Hong Kong, providing important information on the conservation of overwintering danaids.
Over 70% of Lantau Island still maintains its natural form and has a very large degree of biodiversity. On the other hand, large scale development plans are being completed or in the process of being implemented, posing a threat to local habitats. Our surveys help us to gain further understanding of the dragonfly habitats and carry out conservation work of those areas.
Tung Chung River is among the few local rivers that are still free of pollution and have a natural estuary, nurturing several rare species. However, large scale development has never stopped at Tung Chung since 1990s, we are concerned with the Tung Chung River ecology, and will continue our ecological monitoring in these areas.
