In areas where the habitat is relatively undisturbed, halting further habitat destruction may be enough. [3] In areas where habitat destruction is more extreme (fragmentation or patch loss), restoration ecology may be needed. [60] Education of the general public is possibly the best way to prevent further human habitat destruction. [61]
