Same for myself. I will admit that I had no idea this is what was happening to trees even I first began my journey. After being well into my journey and deciding I wanted to source muy own material,  I began researching on how to do so, which lead me to Acacian's and others posts about sustainable and alternative harvesting to protect these trees. After that, as well as the complexities of harvesting in public where I live,  I decided the best thing to do way establish a private ethnobotanical collection that could be properly maintained and cared for, as well as properly harvested.
