What factor, related to habitat quality, can push the twig snake's average lifespan toward the shorter end of its spectrum?

Answer

Habitat fragmentation forcing terrestrial hunting.

If the primary arboreal habitat is fragmented, the snake may be forced into terrestrial hunting more often, increasing its risk of predation or accidental death, thus shortening its average lifespan.
