Ecological Effects of Cannbis


Many states in the western U.S. are decriminalizing recreational cannabis, but the effects of this policy change on the environment are largely unknown. Because cannabis is often grown in rural regions, particularly in Northern California, there are concerns about its impact on wildlife, especially from the rapid rise in greenhouse cultivation.

Research is underway at HREC that examines the effects of greenhouse lighting and noise pollution on multiple wildlife taxa including mammals, birds, and invertebrates. Experimental noise and light simulators have been erected across the site, allowing for data collection on the direct and indirect impacts to the surrounding ecological communities. Results will help to bring an environmental perspective to the discussions around best management practices for cannabis.
