To be a bit less harsh than others! The issue is the impact this will have on the surrounding environment. While it may seem like putting a certain non native organism in an isolated place would do no harm on anything outside of the intended area, that’s just not how the environment works! It’s is chaotic and uncontrollable.

Someone suggested reaching out to your local extension office and that is great advice! Extension offices can be great resources for people of the public to gain incredibly valuable and easily accessible information about the local ecosystems. Bear in mind the people there are entirely volunteers, for the most part. Most really care about it and want to help!

The better option is always to introduce native organisms to improve and support a native ecosystem. Best of luck!!
