International Trade Status and Crisis for Snake Species in China

Abstract:  In recent years, the purchase of snakes for leather, food, and traditional medicine has increased in China, which has greatly reduced certain snake populations. Trade records show that since the 1990s, with respect to some species of snakes, China is changing from a net export country to a net import country. We analyzed data on international trade in snake species, concentrating, in particular, on trade dynamics and species composition. The overall number of snakes exported appears to have decreased in the last 10 years. However, the number of snakes imported during this period has increased steadily. Many species of snakes that are traded in significant numbers are endangered or threatened species. To conserve snakes in China, we recommended that the Chinese government and the international conservation community take the following actions: enhance legislation and list several species in the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) appendices; register all snake farms in China; carry out population and market surveys; monitor the dynamics of trade; encourage biological research; encourage change in food habits; and enhance cooperation between Hong Kong and mainland China.     

Enhancing Sustainability of the International Trade in Seahorses with a Single Minimum Size Limit

Abstract:  Management tools are needed to help regulate the international trade in seahorses (  Hippocampus spp.) under the Convention on International Trade in Endangered Species (CITES) of Wild Fauna and Flora. Given the limited understanding of seahorse population dynamics and fishing mortality, a single minimum size limit for all seahorse species appears to be a useful initial step toward adaptive management, both biologically and socially. We collected data on maximum height and size at first maturity for 32 seahorse species and cross-validated the data with results from an analysis across marine teleosts. A minimum height restriction of 10 cm would permit, based on calculated data, reproduction in 15 species before they recruited to the fishery. Of the remaining 17 species, 16 were essentially not in international trade, were safeguarded under domestic legislation, or were partly protected by this size limit. Only one species, H. kelloggi , was not well served by the 10-cm minimum size limit. The CITES technical committee on animals has now decided to propose this single size limit to all 167 signatory nations as one option toward sustainable trade. Complementary management measures for seahorses are also required, particularly for populations primarily exploited in bycatch.     

区域开发SEA综合评价体系初探

根据区域可持续发展的要求,为了实现区域环境保护从战略酝酿阶段就参与区域国民经济综合评价,本文首次尝试提出了一套实际操作性强的、定量的、着眼于整体的区域可持续性发展SEA综合评价模式,并以成都市羊安工业集中发展区为例,从经济、社会、环境三个子系统出发建立指标体系对其进行综合评价。     

广西喀斯特地区的开发与珍稀濒危植物保护

广西喀斯特岩溶石山面积占全区总面积的33.3%,森林植被的严重破坏是这些地区贫困落后的主要原因。对广西喀斯特地区的综合治理开发,要重视对森林植被及珍稀濒危植物的保护。该区至少有290种石山植物为珍稀濒危植物,它们中许多有重要经济用途,在保护的基础上,引种发展一些种类是山区脱贫致富的一条途径。
