Persecution and exploitation

Some species in Minnesota are negatively impacted by recreational or commercial overexploitation (e.g., reptiles, orchids, medicinal herbs) or by indiscriminate killing due to some perceived threat or undesirable quality.

The major cause of the timber rattlesnake's decline in Minnesota is its vulnerability to systematic and willful destruction by humans. Snakes at den sites are particularly vulnerable to disturbance and poaching.
