Given the task definition and input, reply with output. In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.

Passage: While Colton Point and Leonard Harrison State Parks and parts of the surrounding Tioga State Forest are now the Pine Creek Gorge National Natural Landmark, it is their status as part of a Pennsylvania State Natural Area that provides the strongest protection for them. Within this Natural Area, logging, mining, and drilling for oil and gas are prohibited.  Furthermore, only foot trail access is allowed. In 1988 the Pennsylvania Department of Environmental Resources, precursor to the DCNR, described it as about 95% State owned, unroaded, and designated the Pine Creek Gorge Natural Area. It is a place of unique geologic history and contains some rare plant communities, an old growth hemlock stand, ... active bald eagle nest[s] ... and is a major site of river otter reintroduction. Departmental policy is protection of the natural values of the Canyon from development and overuse, and restoration of the area to as near a natural condition as possible.
Fishers, medium-sized weasels, were reintroduced to Pine Creek Gorge as part of an effort to establish a healthy population of fishers in Pennsylvania. Prior to the lumber era, fishers were numerous throughout the forests of Pennsylvania. They are generalized predators and will hunt any smaller creatures in their territory, including porcupines. Elk have been reintroduced west of the gorge in Clinton County and occasionally wander near the west rim of the canyon. Coyotes have come back on their own. Invasive insect species in the gorge include gypsy moth larvae, which eat all the leaves off trees, especially oaks, and hemlock woolly adelgids, which weaken and kill hemlocks. Invasive plant species include purple loosestrife and Japanese knotweed.
What type of animal is a generalized predator that will hunt any smaller creature in their territory?
