One of the greatest things about Hong Kong is that wildlife flourishes even in the heart of the concrete jungle, thanks to the urban 'blue-green' areas which have allowed species that are more accustomed to urbanised environments to live in the city.

Hong Kong has thousands of parks and gardens for the use of the general public. With their various landscaping features, including lawns, tree canopies, bushes and shallow ponds, they provide a network of habitats in the middle of the urban area for wildlife, particularly birds and butterflies. Man-made slopes that use native species as vegetation covers also provide habitats for birds and insects.

In recent years, the Government has also enhanced biodiversity by introducing eco-conservatory elements to the natural stream habitats for fish and other aquatic wildlife. For example, after the completion of the Upper Lam Tsuen River Improvement Works in 2012, the numbers of bird, fish and dragonfly species were restored to pre-construction levels. In particular, the population of one rare species in Lam Tsuen River, Hong Kong Newt (Paramesotriton hongkongensis) exceeded the previous level from just over 200 recorded by pre-construction baseline monitoring to more than 600 in 2017.
