Answer:
Replenishing resource management.
Explanation:
A replenishing resource management dilemma is, as the exercise exemplifies, a problem in which a group shares a renewable resource (such as trees) that will continue to benefit the group as long as it's not exploited but in which anyone in that group will benefit from taking as much as possible.
Just as the example details, if they take a lot ot wood the woodcrafters will be beneficiated but, if they do so, they may not have enough wood for later given that the trees will not grow as much. That's the replenishing resource management dilemma.
