In Tram Chim National Park in Dong Thap Province, 13 bird species are in danger of extinction and need protection, according to park authorities.

The species include red-headed cranes, white- winged ducks, yellow-breasted buntings, common kestrels, eastern grass owls, eastern marsh-harriers, spot billed pelicans and painted storks.

The number of red-headed cranes returning to the park fell from more than 1,000 in 1988 to nine in 2019, and none this year. This was partly due to a decline in cỏ năng kim (Eleocharis ochrostachys) and cỏ năng ống (Eleocharis dulcis) which provide food for the bird. 

Red-headed cranes, which stand up to 1.8 metres tall and are the world’s tallest flying bird, are the symbol of the park.

The park, which covers an area of more than 7,300ha and contains mostly cajuput trees, is a Ramsar wetlands site of international importance.

The park has about 800ha of lúa ma, which can be translated to ‘ghost rice’ (Oryza rufipogon) for its ability to survive flooding. The rice variety has genes which scientists use to create new rice varieties as the rice can grow in alum-affected soil and is highly resistant to diseases transmitted by brown planthoppers and white-backed planthoppers, and can grow in deep floodwater.

In the past, lúa ma grew wildly in the delta’s flooded areas during the flooding season, but the rice variety now exists in only a few places in the delta, including in the park.

In An Giang and Dong Thap, the number of basa catfish fish in the wild has become scarce because of the low level of floods caused by the rising level of the Mekong River in the rainy season.

Nguyen Huu Nguyen, director of the Chau Thanh District Tra Fish Breeding Co-operative in An Giang, said the number of wild basa fish in rivers has become scarce, so fishermen who live on catch the fish have switched to other occupations.

In Ca Mau Province, which is the country's largest shrimp producer, the number of wild birds has declined significantly in recent years because of hunters and fewer rice fields.

Nguyen Huu Danh, 78, from Ca Mau’s Cai Nuoc District, said that previously most localities in the province planted rice, so many wild birds came and fed on the rice fields.

After more rice farmers in the provinces switched to breeding shrimp, the number of wild birds fell significantly because of the decline in food resources, he said.

Overhunting has also led to the decline in wild birds, according to experts. 

Preservation

To preserve endangered fauna and flora species, local authorities in the delta have focused on preserving wetland areas and forests to provide natural habitats for birds, fish and plants.   

In Ca Mau Province, authorities are implementing a plan to develop the Ca Mau City bird garden located in the Ho Chi Minh President monument area in the 2018-20 period.

They have planted more trees to provide a better habitat for birds, upgraded water ditches in the garden to supply clean water for birds, and solved pollution caused by bird waste.

The 3.1ha garden has about 53 species and 6,600 birds. The number of wild birds at the garden can reach more than 12,000 in the peak reproductive season in June and December.

In Dong Thap, local authorities are preserving three wetland areas – Tram Chim National Park, the 279ha Go Thap Relic Area in Thap Muoi District, and the 63ha Xeo Quyt Relic Area in Cao Lanh District.

Xeo Quyt has 20ha of primitive cajuput forests, 170 flora species and 200 fauna species, including 13 fauna species listed in the Vietnam red book of endangered species.

Every year, the three wetland areas in co-operation with the province's Forest Protection Sub- department devise plans to protect their biodiversity.

Since 2016, the sub-department, in co-operation with the people’s committees of communes where there are wetland areas and forests, has organised 40 courses for 2,000 residents about legal regulations that protect forests, biodiversity and wild animals.

It has also given local people 1,650 booklets and 19,000 leaflets about protection of wild animals in the forests.

The Tram Chim National Park is taking steps to preserve the wetland ecosystem and the genes of flora and fauna species, especially endangered birds like the red-headed crane and white-winged duck.

The park is building an experiment station to develop biodiversity, and is investing in infrastructure for ecotourism services.

Nguyen The Hanh, director of Tram Chim National Park, said: “To protect the park’s biodiversity, especially in the dry season, the park is also focusing on preventing and controlling forest fires.”

The park has more than 130 flora species, 129 freshwater fish species, 198 water birds, and 29 amphibian species.  VNS
