Diversity of medicinal plant resources in Lai Son island, Kien Giang province

Abstract

This study was conducted with the aim of assessing the diversity of medicinal plants in Lai Son Island, Kien Giang province, which is a scientific basis for more effectively using, managing, and preserving this medicinal plant resource in this province. In this study, the PRA (Participatory Rural Appraisal), field investigation, morphological comparison, and classification, with the aid of specialized medicinal plant books were used. The results showed a total of 353 species of medicinal plants belonging to 264 genera of 112 families in 4 divisions. Among them, Magnoliophyta was the most diverse division with 94.90% % species, 95.08% genera, and 90.18% families. Seven species were listed in “Red List of Vietnamese medicinal plants” (2006), “Vietnam Red Book” (2007), and the Decree 06/2019/ND-CP. The medicinal plant species were divided into ten life forms and distributed in six biotopes. The most species diversity was recorded in the natural forest on rocky mountain biotope. Ten parts of plants were used to medicate 36 disease types. Twenty-four species were commonly used by local people.

ADDITIONAL INFORMATION OF AMPHIDROMUS INVERSUS ANNAMITICUS (CROSSE & P. FISCHER, 1863) (GASTROPODA, STYLOMMATOPHORA, CAMAENINAE) FROM VIETNAM

“…), and mountains in An Giang Province, no reports were found in the plains. In the survey of three islands of Kien Giang Province, Nguyen and Nguyen found that the subspecies usually hang on the branches and leaves of mango trees (Laidlaw and Solem, 1961;Sutcharit et al, 2006;Schileyko, 2011;Inkhavilay et al, 2017;Nguyen and Nguyen, 2016). On the contrary, there were no individuals of the snail found in that type of tree but in landscaping plants (Dipterocarpus alatus, Samanea saman, Khaya senegalensis, and Erythrina fusca) in this study.…”

“…Distribution: Vietnam (Kien Giang, An Giang, Ho Chi Minh city, Dong Nai, Phu Yen); Cambodia; Thailand; Laos (Laidlaw and Solem, 1961;Sutcharit et al, 2006;Schileyko, 2011;Inkhavilay et al, 2017;Nguyen and Nguyen, 2016). Prior to this study, several records found A. inversus annamiticus in the Cuu Long River Delta only in mountains and islands of Kien Giang Province (Kien Luong Distr., Ha Tien Distr., and Kien Hai Distr.…”

“…Specimens' identification: Snails collected were identified the morphologies of their shells as follow the descriptions and keys of Sutcharit and Panha (2006), Nguyen and Nguyen (2016); plants identifications and information were used followed the description on National Parks Flora and Fauna Web (2023). The source of species names and synonyms were from Crosse and Fischer (1863), Mabille and Mesle (1866), Morlet (1889), Pilsbry (1900), Laidlaw and Solem (1961), Solem (1965), Sutcharit and Panha (2006), Schileyko (2011), Nguyen and Nguyen (2016). Gude (1902), Abbott (1989), andZilch (1953).…”

“…The terrain of the Cuu Long River Delta is almost plain, with some mountains and islands in the west, the bordering Cambodia and Thailand gulf (Le et al, 2010). Besides the data of land snails reported in mountainous and islands with 45 species recorded, there were Additional information of Amphidromus seven species found in plain of Tram Chim National park (Dong Thap Province) and Cu Lao Dung (Soc Trang Province) (Pfeiffer, 1861;Crosse and Fischer, 1863;Bavay and Dautzenberg, 1909;van Benthem Jutting, 1962;Vermeulen et al, 2007;Schileyko, 2011;Do et al, 2012;Nguyen and Nguyen, 2016;Nguyen et al, 2020;Tran et al, 2021). Also, there was no report of A. inversus annamiticus in the plain of the delta.…”

Đa dạng hệ thực vật bậc cao ở đảo Lại Sơn, tỉnh Kiên Giang

“…Hệ thực vật ở đây ngày càng bị suy thoái, nhiều loài quí hiếm đang có nguy cơ tuyệt chủng, trong khi sự tái sinh của chúng trong môi trường tự nhiên lại rất chậm và khó có khả năng phục hồi. Mặc dù đảo Lại Sơn là một đảo khá lớn, có nhiều người dân sinh sống và du lịch rất phát triển, nhưng mới chỉ có công trình nghiên cứu về tài nguyên cây làm thuốc được công bố (Quan & Phuc, 2022), còn nhiều loài thực vật có các giá trị sử dụng khác vẫn chưa được nghiên cứu. Do đó, việc điều tra, đánh giá thực trạng đa dạng hệ thực vật hiện có ở đảo Lại Sơn là rất cần thiết, từ đó có thể cung cấp cho người dân địa phương những tri thức hữu ích về việc nhận diện, khai thác sử dụng và bảo tồn có hiệu quả hơn nguồn tài nguyên thực vật trên đảo.…”
