État de la populationExpert
Best estimates for the total (regional) population size of Macrozamia flexuosa are between 1,740,000 and 43,500,000 individuals. In the absence of quantitative data within replicated sample areas, this is based on an extrapolation of plot-based cover abundance data across the calculated area of occupancy for this species (Bell 2019).
