Preliminary study on resource status and priority conservation of rare and endangered plants in Tianxin Provincial Nature Reserve,Lianzhou,Guangdong Province
Mastering the basic situation and threatened status of rare and endangered plants,improving the priority protection evaluation system for rare plants in protected areas,can provide a basis for formulating protection strategies and scientific management in protected areas.Field investigation and data colleation were used to study the rare and endan-gered plant resources in Tianxin Provincial Nature Reserve.The findings reveal that Tianxin Provincial Nature Reserve of Guangdong has a total of 35 families,63 genera,and 94 species of rare and endangered species,of which 25 families,33 genera,and 46 species are national key protected wild plants;7 families,10 genera,and 10 species are key protected wild plants of Guangdong Province;20 families,25 genera,and 25 species are rare and endangered plants in China Plant Red Data Book.There are 5 families,23 genera,and 46 species of plants listed in CITES.41 species of rare and endan-gered plants were ranked by the priority protection evaluation system.The results show that 2 species belong to level Ⅰprotection,accounting for 4.88%;22 species belong to level Ⅱ protection,accounting for 53.66%;17species belong to level Ⅲ protection,accounting for 41.46%.The excellent habitats and abundant rare and endangered plants indicate a great conservation value in the nature reserve.The evaluation and classification results of 41 species of plants in this evalu-ation system more truly reflect their threatened status and priority protection order in the Tianxin Provincial Nature Re-serve,which has certain guiding significance for the priority protection of rare and endangered plants in this area.
