No. Removing natural materials from the park is prohibited. I would suggest looking in National Forest lands nearby.
There are signs posted that it is prohibited. Largely up to you and your conscience as there are tons of potential finds
Not advised.
From personal experience, the collection of plants, wood and rocks is prohibited in state parks
Probably not since it is a state patk. There's a ranger station and gift shop on premises and you can get a definitive answer from them.
Picking up branches for an aquarium is not i good thing anyways they have not been treated an could cause harm to your fish..
They have a sign that says you may not remove plants or animals from the park.
