This not only impacts waterways and increases fire severity, but it creates financial burden on taxpayers. In California, over $80 million and countless hours of painstaking labor is spent each year addressing invasive plants. This does not include financial losses from reduced agricultural yields, land values, and recrea onal opportuni es. By Plan ng Right, you are protec ng our natural resources, local ecosystems and our economy.
