The conservationists shared a portion of the revenue from the park with the adjacent villages. This helped create a symbiotic relationship between the gorillas and villages.

Not saying that this solution will work with poachers but there is probably a combination of approaches needed to preserve the biodiversity. One national park in India has given legal protection to park rangers if they were to kill to poachers and that has had a dramatic impact on the population of single horned rhinos. In 2015 park rangers shot dead more poachers than poachers killing rhinos for Chinese medicine.
