Macarthuria keigheryi is a rare and endangered plant found only in the Southwest of Western Australia, facing serious challenges with natural regeneration and seedling survival. Despite producing seeds, most fail to germinate or establish, and little is known about its reproductive biology in the wild, including germination requirements and capacity for vegetative propagation. This study aims to understand the key factors that influence its reproductive success, including how its flowers are structured, which insects pollinate it, and what environmental conditions affect seed germination and vegetative growth. Field surveys, pollinator observations, and seed experiments will be combined with propagation trials using both root and stem cuttings under controlled nursery conditions. By investigating both sexual and asexual reproduction, the study seeks to identify practical methods for improving seedling establishment and population recovery. The insights gained will directly support conservation efforts by guiding habitat restoration and translocation strategies, helping secure the long-term survival of M. keigheryi in its native habitat.
