Assisted Migration (AM) is generally defined as the practice of manually moving plant populations to allow for quicker climate change adaptation. In theory, moving plants to more suitable ranges as we continue to experience various climate anomalies may decrease the threat of species extinction while supporting biodiversity and ecological resilience. However, steady implementation is limited by the lack of research and various ecological risks associated with the practice. The aim of this study was to evaluate local perception and awareness of AM tactics, as well as identifying possible ways to safely implement them considering the current boundaries in doing so. I worked with Friends of Lincoln Park to remove invasive blackberry and English Ivy cover and restore native vegetation in West Seattle while collecting survey data pertaining to local perception of AM practices. Additionally, I conducted a literature review to decipher common methodology used for AM policy, as well as what debate surrounds the practice. Based on my literature review and survey data, there is a high urgency for climate change adaptation, yet increasing opposition exists with the lack of research and potential ecological risks associated with more drastic forms of implementation. Thus, it is vital AM research continues to be prioritized as climate change becomes increasingly imminent. Including various types of knowledge and stakeholders in the decision-making process may account for diverse interests and avoid the equally-plausible threat of inaction.
