摘要

吉德拉尔具有多种重要意义,由于兴都库什山脉、喜马拉雅山脉和喀喇昆仑山脉交界,被指定为该国的生物多样性热点地区,因此拥有最多的特有植物。根据《世界自然保护联盟红色名录》2011 年、2017 年的分类和标准,对这些特有植物的保护状况进行了三年评估,其中至少有几个点的数据,并使用 "GeoCat "进行 AOO 和 EOO 评估时更依赖于 B 标准。其中一些分类群还与其十年前的评估状况进行了比较。该指南将有助于制定国家保护、威胁评估和可持续管理政策。在对 15 个特有分类群(物种和亚种)进行评估后发现,除了 Anaphalis chitralensis 和 Impatiens lemannii(均为吉德拉尔特有种)外,大多数分类群均为吉德拉尔特有种。12 个物种符合濒危(EN)标准,2 个物种属于易危(VU)类别,1 个物种属于极度濒危(CE)威胁类别。CE(极度濒危)物种中最多的是黄芪(Astragalus commixtus),只有 56 个成熟个体,而黄芪(Astragalus erionotus)、Delphinium kohatense 被认定为 VU(易危)物种,其余所有物种如蓼(Polygonum cognatum)、Plocama asperuliformus 等都属于 EN(濒危)物种。这些物种的生存需要立即采取原地和异地保护战略。

Conservation assessment of endemic plants from Chitral Region, Pakistan
Chitral has diverse importance and has designated as a biodiversity hotspot of the country due to junction of Hindu Kush, Himalayan and Karakorum ranges, thus supporting maximum number of endemic plants. The conservation status of those endemic plants was assessed for three years, which have at least few points’ data as per IUCN Red List Categories and Criteria 2011, 2017and relied more on B criterion using “GeoCat” for AOO and EOO assessment. Some of the taxa were also compared with their previous status assessed ten years ago. This guideline will assist in country’s policies for conservation, threat assessment and sustainable management. Assessing a total of fifteen endemic taxa (species and subspecies), most are endemic to Chitral except Anaphalis chitralensis and Impatiens lemannii (both country’s endemic).Twelve species fall in the criteria for Endangered (EN) where as two species fall under Vulnerable (VU) and one falls in critically endangered (CE) threat category. The most CE (critically endangered) species is Astragalus commixtus with only 56 mature individuals while Astragalus erionotus, Delphinium kohatense were found to as VU (Vulnerable), rest all species like Polygonum cognatum, Plocama asperuliformus etc. are EN (Endangered). These species need immediate strategies for in-situ and ex-situ conservation for survival.
