ASIA / PACIFIC SOUTH CHINA KARST (PHASE II) (Extension of the “South China Karst”) CHINA China – South China Karst (Phase II) WORLD HERITAGE NOMINATION – IUCN TECHNICAL EVALUATION SOUTH CHINA KARST (PHASE II) (CHINA) – ID No. 1248 Bis IUCN RECOMMENDATION TO WORLD HERITAGE COMMITTEE: To approve the extension under natural criteria. Key paragraphs of Operational Guidelines: Paragraph 77: Nominated property meets World Heritage criteria. Paragraph 78: Nominated property meets integrity or protection and management requirements. Background note: This nomination of Phase II of the South China Karst (SCK) seeks to extend Phase I of the property which was inscribed under criteria (vii) and (viii) in 2007 (Decision 31 COM 8.B11). At the time of the first inscription of SCK the World Heritage Committee recommended that the State Party consider this as Phase I of a larger World Heritage nomination, and consider whether the extent of subsequent phases of the entire series could be rationalized into a smaller number of sites and a single phase of nomination rather than two phases. The Committee added that the potential application of criterion (ix) should be considered in relation to the entire series that is eventually proposed. The Committee also recommended a number of other actions to the State Party including review of the boundaries of the (Phase I) Wulong cluster; continued efforts to manage catchment areas with the potential to impact on karst values; continued efforts to positively engage local people in management and future additions to the site; and urging transnational collaboration with Viet Nam on karst systems. 1.

SUMMARY OF NATURAL VALUES c) Additional literature consulted: Various sources listed in the nomination, and in the earlier IUCN The nominated area for Phase II of the South China evaluation report, including Ford and Williams (2007) Karst (SCK) covers a nominated property of 49,537 Karst Hydrology and Geomorphology.

It also serves as the type locality simultaneously. Guilin Karst represents the near end for two globally significant karst landforms – fengcong stage of geomorphological evolution of karst in a humid and fenglin. Fengcong is an extensive limestone tropical to subtropical environment. Guilin Karst is widely landscape made up of conical peaks separated by acknowledged as having the world’s best expression of irregular depressions and valleys. Rates of limestone a tower karst landscape and has been internationally solution are enhanced by tropical and sub-tropical recognized as the type-site of continental tower karst. vegetation and abundant rainfall. Drainage is thus Due to its scenic quality the Guilin Karst is an extremely entirely underground, caves can occur at several levels popular tourist attraction in China. and these can feed large springs. Where large rivers intersect this karst, basal corrosion and cliff collapse The Shibing Karst is a spectacular and very unusual produce steep-sided, tall karst towers termed fenglin. fengcong karst with gorges developed in pure, thick and ancient dolomite rocks. The area displays strong karst The karst terrain displays a geomorphic transition as the development in a mid-subtropical karst gorge area with terrain gradually descends about 2000m from the deep river incision. The area demonstrates that relatively western Yunnan-Guizhou Plateau to the eastern insoluble dolomite can also develop typical and Guangxi Basin. The existing SCK sites together with the spectacular karst landforms, provided environmental currently nominated extension track the evolution of conditions are appropriate. The Shibing Karst displays karst development from the high inland plateau of varied karst landforms including flat top hills, cliffs, and Yunnan, where ancient karst remains almost canyons resulting in columnar-shaped isolated peaks, undissected, to the lowlands of Guangxi where karst tufted-peak-clusters, and knife-ridge mountains. landforms can be seen in their final stages of evolution Numerous vertical fractures with almost horizontal as isolated karst towers on corrosion plains. stratification in massive dolomite are responsible for these special landforms which are quite distinguishable The Guilin Karst has been developed in massive from limestone landforms. Devonian limestone which has been folded. Differential tectonic processes combined with allogeneic (rainfed) The Jinfoshan Karst is a unique karst table-mountain water input and special hydrological conditions in a characterized by underground river and cave systems humid climate provide excellent conditions for the with high altitude and multi-level planation surfaces formation of various karst landforms. The area is surrounded by massive towering cliffs. Jinfoshan characterized by fenglin (tower karst) as well as illustrates the process of dissection of the high elevation fengcong (cone karst) landforms. Because of differential karst plateau by deep fluvial incision and contains tectonic movements and associated contrasting evidence of the region’s intermittent uplift and hydrogeological conditions, fenglin karst was able to karstification since the Cenozoic. Thus Jinfoshan has 20 IUCN Evaluation Report – April 2014 China – South China Karst (Phase II) been isolated from the high inland plateau by incision of criterion (vii) or (viii); there are another 31 on Tentative the surrounding rivers.
