Effectiveness of Local Biodiversity Action Plans to Identify Locally Rare and Endangered Fish in Scotland

Biodiversity loss is an important environmental issue globally. Local Biodiversity Action Plans (LBAPs) provide an important conservation tool and should represent national priority species where they are present. Although much effort has gone in to developing LBAPs, their value as a conservation tool has been questioned. Here the effectiveness of the LBAP system to raise awareness of the freshwater fishes of national and international priority in Scotland is tested. Inclusion of freshwater fish in the LBAP suite was evaluated using current distribution data taken from available literature sources. Of the 25 examined LBAPs in Scotland, there were 79 LBAP entries for the 12 priority freshwater fishes found in Scotland. This contrasts with an expectation of 139 entries. Nineteen authorities failed to represent all priority freshwater fish species extant in their geographical boundary. Fourteen authorities provided cover for 50% or less for the species distributed in their area and five authorities included no rare freshwater fish species where one or more was expected. Possible underlying reasons for this mismatch include: frequently changing conservation status and taxonomic blindness of this group. It is plausible to suggest that this low rate of inclusion will have a detrimental effect on the allocation of limited conservation resources.     

环境压力与土地利用形式的转变——以汾阳文湖变迁为例

文湖是古代晋中重要湖泊之一,宋、金以前,湖域广阔,有着重要的社会经济效益。随着人地矛盾压力增大,宋、金已有两次开渠泄湖,到了万历四年彻底泄湖,文湖随即消亡。通过对文湖变迁过程的环境因素分析,本文认为文湖土地利用形式的转化,是区域自然、人文环境压力日趋紧张作用的结果,在看到泄湖为田之后的负面影响时,也应指出在区域生态环境长期发展下的行为适应性和无奈。这种因环境压力而导致的适应性土地利用行为,是历史时期人类土地利用形式转变的共性之一。
