Eyes on PolyU

Something about Hong Kong’s biodiversity

Hong Kong is a cosmopolitan metropolis with many skyscrapers to illustrate its urbanicity. It is the place that approximately 7.31 million people call it home. It is known around the world as a leading financial centre. Despite all these, will you be surprised to know that Hong Kong is also the home to an impressive range of wild life?

To share more information about Hong Kong’s rich biodiversity with the university community, the Campus Sustainability Committee and Campus Sustainability Office jointly staged an interesting session recently. The invited speaker explored into the various precious species within Hong Kong’s borders and interestingly explained to the audience the natural environment of Hong Kong. Meaningfully, this event was held on 5 Jun to echo World Environment Day, encouraging the university community to think about what we can do for our environment.

Seminar on Hong Kong’s biodiversity Sharing

For a city sitting on only 1,104 sq km of land, Hong Kong is exceptionally rich with different species of plants, insects, reptiles, marine life and other animals. Some of these species in fact stay in our urban neighbourhood and can be visibly identified around us. Local specialists say there are 51 butterfly species in the urban parks of Kowloon1. A recent Hong Kong sparrow census speculates that there are around 320,000 Eurasian tree sparrows in the city (a higher density of bird population compared to that in the United Kingdom!) and they mostly stay in urban districts2. The city also has species that are exclusive to the territory such as the Romer’s treefrog. With these facts, it is not difficult to know that Hong Kong’s biodiversity is much greater than that we can imagine.

As a member of the campus community and an individual, we can do a lot more for our environment. We can offer our support for the protection of biodiversity by increasing our knowledge of environmental issues and the local habitat. We can participate in biodiversity-conscious activities and share the message with our families, colleagues and friends. Most importantly, we should keep in mind that we live together with all these species on Earth and there’s no reason we should put them in endangered situations.
