Prior to the eruption, Mount St. Helens was a recreation destination in southwest Washington with active fishing, hunting, camping, and hiking. Imagine that you were a U. S. Forest Service officer during this time. What restrictions, if any, would you have placed on these activities during the recovery period to protect the ecosystem

No fishing and hunting.

Explanation:

No fishing and hunting is banned in the Mount St. Helens in order to protect the ecosystem. The banning and restriction on these activities will leads to recovery of the ecosystem. Camping and hiking will be allowed because it can't affect fish and other animals in the ecosystem. So I was a U.S. Forest Service officer, I will ban fishing and hunting in the  Mount St. Helens to protect animals in the recovery period.
