Description complète des menacesTexte détaillé évaluation IUCNExpert
The main threats to Macrozamia parcifolia are loss and damage through forestry operations; inappropriate fire regimes, which kill surface seed and young seedlings; failure of the insect pollination mutualism; and vulnerability to poaching (Hill and Osborne 2001). Regeneration of the species is limited as plants are slow-growing, seed is set intermittently, plants produce low amounts of seed, and seed have limited dispersal (Jones 2002).
