Ecology of<i>Nepenthes clipeata</i>on Gunung Kelam, Indonesian Borneo

Background Nepenthes clipeata is a Critically Endangered plant species with the population at its only location in wild, Gunung (Mount) Kelam Kalimantan, Indonesia, under threat – nutrient relationships have not been studied.Aims To improve understanding of autecology N. by assessing current and providing information on mineral relationships.Methods A survey was undertaken 2019 when numbers habitat preferences were recorded. Nutrient concentrations soil, leaves pitcher fluid analysed compared those other species.Results Eighteen individuals found (only one which female). Seven hybrids two these observed. Although foliar (‘ionome’) appeared distinct from that species, having greater concentrations, particularly nitrogen, potassium calcium, nitrogen limitation still prevalent.Conclusions persists wild but very low numbers, indicating conservation actions are required. Along Nepenthes, it limited soil although has ionome derived high concentrations.
