Biogeography, Conservation Status, and Traditional Uses of Zingiberaceae in Saraburi Province, Thailand, with Kaempferia chaveerachiae sp. nov.

Abstract

This research investigates the Zingiberaceae family in Saraburi Province, Thailand, aiming to understand its biodiversity, distribution, ecology, conservation status, and traditional uses. Through systematic exploration, 103 species are identified, including a novel species, Kaempferia chaveerachiae Saensouk, P.Saensouk, and Boonma. Additionally, 23 species are newly reported for distribution in Saraburi Province. Methodologically, a district-wise analysis and the unweighted pair group method with arithmetic mean (UPGMA) cluster analysis were employed to discern species prevalence and geographical patterns. Findings reveal varied species distribution aligned with diverse ecological conditions, informing targeted conservation strategies. Fourteen endemic species and the District Endemism Index emphasize localized conservation significance. Assessment of conservation status highlights critical and vulnerable species, prompting focused conservation initiatives. Phenological analysis underscores adaptability through flowering peaks tied to environmental cues. Ethnobotanical insights highlight the multifunctionality of Zingiberaceae, emphasizing its cultural significance and traditional applications. This study offers valuable insights into Zingiberaceae diversity, advocating for tailored conservation strategies and sustainable practices in Saraburi Province to safeguard its unique flora, habitats, and indigenous knowledge.
