Invasive species (plants, animals, or diseases) are those intentionally or accidentally introduced by human activity causing ecological or economic damage within a region in which they did not evolve. These species are usually characterized by unrestricted growth with few natural pests or predators. These qualities allow them to spread quickly, and they can aggressively outcompete desired native species causing harm to natural resources, humans, and the local economy.
Here are some ways that invasive species are introduced to new areas: Pathways of Introduction and Spread.

As of January 1, 2023, running bamboo must be contained on an owner's property.
Avoid The Fine, Don't Let Running Bamboo Grow Beyond Your Property Line.
Running bamboo is a fast-growing, invasive grass with a complex, horizontal root system called rhizomes that aggressively spread underground, as much as 15 feet per year. Once planted, running bamboo can eventually take over yards and travel across property lines, creating issues for adjacent property owners and local jurisdictions.
The new ordinance requires property owners to contain running bamboo on their property and prevent it from spreading beyond their property line. Property owners may incur penalties if they allow bamboo to spread beyond their property.
Learn more about the damage it causes, as well as how to contain, remove and dispose of Running Bamboo.

Countywide Strategic Plan - Environment and Energy Outcomes
