(Rotifera) Der Insel Hainan, China. Teil 11
Osnabrücker Naturwissenschaftliche Mitteilungen Band 24, S. 183-222, 1998 Zur Kenntnis der Rotatorienfauna (Rotifera) der Insel Hainan, China. Teil 11. Walter Koste & Van Zhuge Kurzfassung: Im Dezember 1995 wurden aus verschiedenen Gewässertypen der Insel Hainan, China, Proben genommen, um sie auf das Vorkommen von Rotatorien (Rädertiere) zu untersu- chen. Es konnten 195 Spezies nachgewiesen werden, davon 187 monogononte und 8 digononte (bdelloide) Arten. Daneben wurden Formen aus 5 Gattungen und Bdelloidae beobachtet, deren Identifikation aufgrund von Konservierungsartefakten nicht möglich war. Von den nachgewiese- nen Arten ist Cephalodella qionghaiensis neu für die Wissenschaft, daneben werden von Keratella micracantha eine neue Form und von Notholca acuminata eine neue Varietät beschrieben. Abstract: In December 1995 sam pies were collected from different water bodies located on the Island of Hainan, China. 195 species were found. Among these sampies, there were 187 Monogononta und 8 Digononta (Bdelloidae). Further rotifers belonging to five genera and to the Bdelloidae could not be identified to species level, because determination was hindered by pres- ervation artifacts. Among the species found, Cephalodella qionghaiensis is new to science. Addi- tionally, a new form of Keratella micracantha and a new variety of Notholca acuminata could be described.

Outcome(s): UNDP Strategic Plan Environment and Sustainable Development Primary Outcome: Mobilizing environmental financing UNDP Strategic Plan Secondary Outcome: Mainstreaming environment and energy Expected CP Out come(s): Outcome 4: Low carbon and other environmentally sustainable strategies and technologies are adapted widely to meet China’s commitments and compliance with Multilateral Environmental Agreements; and Outcome 5. The vulnerability of poor communities and ecosystems to climate change is reduced . Expected CPAP Output (s): Output 4.1 Policy and capacity barriers for the sustained and widespread adoption of low carbon and other environmentally sustainable strategies and technologies removed, and Output 5.1 A strengthened policy, legal, institutional framework for the sustainable use of land, water, the conservation of biodiversity, and other natural resources in fragile ecosystems is enforced. Executing Entity/Implementing Partner: Hainan Forestry Department (HFD), Dongzhaigang Nature Reserve Implementing Entity/Responsible Partners: HFD, and Dongzhaigang NR Brief Description Hainan Island has the largest area of tropical rainforest, mature mangrove and coral reef resources in China, constituting one of the country’s most valuable areas for biodiversity conservation. However, the globally significant ecosystems of Hainan Island are fragile and under increasing threat from a number of factors, notably deforestation due to encroachment for agriculture, plantations and urban development. The main wetland areas in Hainan are coastal where pressure is most severe. -

Coral Reef Conservation and Management in China1
Coral Reef Conservation and Management in China1 Qiaomin Zhang Abstract This paper summarizes the status of coral reef conservation and management in China. Coral reefs in China include fringing reefs found in southern China’s coastal waters and associated with 128 atolls in the South China Sea Islands. These atolls have a combined area of about 30 000 km2. As a result of rapid socioeconomic development and population growth in the coastal region of South China over the last several decades, many coral reefs have been seriously damaged or degraded, largely by inappropriate human activities and consequent pollution. Until now, even though the government has taken some measures to protect and manage the reefs – including issuing relevant laws, establishing natural reserves, creating marine zones – the condition of the reefs has continued to worsen. Surveying, monitoring, assessment and research of coral reefs in China needs to be strengthened in order to meet the changing needs for protection, management, restoration, reconstruction and sustainable development of the coral reef ecosystems. Distribution of coral reefs in China Status of coral reefs in China Coral reefs in China include fringing reefs found Because of rapid economic development and in southern China’s continental coastal waters population growth in the coastal regions of South and around offshore islands, and as atolls in the China over the last several decades, many coral South China Sea (Zhao et al. 1999). Typical reefs have been seriously damaged or degraded. fringing reefs occur mainly on parts of the coasts This damage and degradation can be traced to of Hainan Island and Taiwan Island. -
Status of Wintering Waterbirds on Hainan Island: Results of Annual Waterbird Surveys Between 2008−2020
FORKTAIL 36 (2020): 79–89 Status of wintering waterbirds on Hainan Island: results of annual waterbird surveys between 2008−2020 FEI LI, GANG LU, BOSCO PUI LOK CHAN, XI ZHENG, ZHI-QIN ZHOU & YAN-NI MO We conducted annual surveys on wintering waterbirds at a total of 81 wetland sites on China’s Hainan Island from 2008 to 2020. These surveys recorded 82 waterbird species. Little Egret Egretta garzetta, Lesser Sand Plover Charadrius mongolus and Kentish Plover C. alexandrinus were the most abundant species, while Little Egret, Chinese Pond Heron Ardeola bacchus and Common Sandpiper Actitis hypoleucos were the most widespread. We discovered a new and important wintering site for the endangered Black-faced Spoonbill Platalea minor in Danzhou Bay. Our data also suggest that Hainan may be a regular wintering site for a small number of Great Knot Calidris tenuirostris and Nordmann’s Greenshank Tringa guttifer. Sites of particular importance included Dongzhaigang, Houshui Bay, Danzhou Bay, Beili Bay, Changhuajiang River Estuary and Yinggehai Saltpans, but not all of them are formally protected at present. Our longitudinal data suggest an increasing trend in the total number of waterbirds counted, but this most likely reflects increased survey effort over the years, improving field skills of surveyors and a growing knowledge of important waterbird sites. The average annual count of waterbirds recorded during our 13-year survey period was relatively low compared with some nearby wetlands of importance on the mainland. Our surveys also detected continuous declines of waterbirds at some sites. To safeguard the future of Hainan’s waterbirds and their habitats, we recommend establishing new or expanding existing protected areas at key sites, and enhancing management and enforcement efforts throughout the island.
