WWF Lobbying Government for Additional Marine Parks

WWF yesterday (31st May) published “Sea for Future: Conservation Priority Sites for Hong Kong”, in which it proposed designating West Lantau, South Lamma, Shui Hau, Ninepin Group and Pak Nai as marine parks.

WWF also proposed to turn Sharp Island and Shelter Island in Port Shelter, as well as Tolo Harbour, into marine protected areas.

This would restrict developments in marine parks, limit boat speeds and ban the collection of marine creatures.

However, compared to marine parks the marine protected areas would have more lax regulations also be regulations.

Under the proposal the waters off Tai O and Yi O would be combined into a western Lantau marine park.

Tai O and Fan Lau are the only remaining core habitats of the dolphins, whose numbers have dropped from 188 in 2003 to just 47 in 2017.

Together with existing plans for two marine parks near Chek Lap Kok and southwest Lantau, the Tai O a marine park would provide a protected corridor for the dolphins during construction of the third runway.

A core dolphin conservation zone around Tai O would ban coastal development and put restrictions on traffic.

The South Lamma, Sham Wan, is the only nesting site for the turtles in HK, and its beach is closed to visitors during their nesting period between June and October.

But waters off the beach are not covered by the ban, and the area is popular with recreational boats. These affect the turtles, as they have to swim past to go onto the beach.

Human disturbances can prevent female green turtles from nesting.

The turtles were last spotted nesting there in 2012. Marine park status would limit human access to the beach and nearby shallow waters, control disturbance to the turtles and limit the speed of vessels to minimize risks of collision.

WWF also suggested making Shui Hau Wan in Lantau a marine park to protect horseshoe crabs. No-take zones should be created, and partial closures should to be implemented during their breeding season.

This should also be done in wetland Pak Nai in Yuen Long, a habitat for globally-endangered black-faced spoonbills.

Dolphins & Porpoise Found Dead During Lunar New Year

A dolphin concern group published on its social media page that one chinese white dolphin (Sousa chinensis) and four finless porpoises (Neophocaena phocaenoides) were found stranded between Saturday the 17th and Monday the 19th of February. Autopsy scans found food remains in the dolphins, showing they were not starved to death. However, they showed multiple fractures. It is feared they were hit by motorboats as they had injuries on their heads and necks.

One finless porpoise was almost cut in half by what is thought to have been a boat propeller.

The adult Chinese white dolphin was found stranded at Mo To Chau. It was a 2.5-meter female, at least 10 years old, and with signs of choking, bone fractures and serious bone dislocation. The death of an adult female is a great loss to the species’ population growth, with numbers in Hong Kong down from over 120 some years ago to 47 at present.

In the past three years there have only been 3-4 stranded cetaceans in tyhe months of January and February. This year, more than 10 dead cetaceans have been discovered in the same period.

High-speed boats are always a big threat to dolphins and some might be hit by propellers and never be discovered. The Dolphin Conservation Society of Hong Kong (HKDCS) has urged the government to launch a speed restrictions on boats around dolphin and porpoise habitats or even ban them from entering these areas.

According to the HKDCS only one new-born Chinese white dolphin was recorded last year. With the loss of another adult female dolphin, there is a dwindling chance of recovery of the local population.

Pretty in Pink – the Chinese White dolphins

Humpback dolphin by Tracy Meintjes There is a lot of information on the internet about the Sousa chinensis, the Indo-Pacific Humpback dolphin, also known as the Chinese White Dolphin or the Pink Dolphin, so I won’t repeat any of it here. Instead here are some links to organizations and people that deal with the topic full-time:

 

But just because I found some old images on my computer, here are 3 blurry images of the dolphins from a distance.
