Question

overharvesting is especially dangerous to this biome because
there is hight biodiversity of trees
the trees take along time to grow to full mature size
there are not regulations
there are an abundance trees

Explanation:

Over - harvesting is dangerous when trees take a long time to reach full maturity as it can lead to depletion of the forest faster than it can replenish. High biodiversity alone doesn't make over - harvesting especially dangerous. Lack of regulations is a contributing factor but not the most fundamental reason for over - harvesting being especially dangerous. An abundance of trees doesn't mean over - harvesting isn't dangerous; in fact, it might lead to more over - harvesting.

Answer:

the trees take a long time to grow to full mature size
