Invasive species include a variety of plants, insects and animals that have been introduced from other regions/ecosystems and cause, or are likely to cause, harm to the economy, environment or human health.

    Invasive species produce a measurable impact and if left unchecked, can threaten native species, biodiversity, ecosystem services, wildlife, water resources, agricultural and forest production, economics and property values.

    These species are a concern because they grow, reproduce and spread rapidly, establish over large areas and persist in the environment. Species that are invasive succeed because of their ability to thrive in favorable environments, due to the lack of natural predators, competitors and diseases that normally regulate their populations.

    It is important to monitor your property for invasive species and take steps to control them when possible. Visit and contact Texas A&M Forest Service or your county extension agent for more information.

    Native – a species that has evolved and occurs naturally in a region, ecosystem or habitat

    Non-native – a species that does not originate in the area or region in which it was found

    Invasive – a plant, animal or other organism that is non-native to a particular ecosystem and whose introduction causes or is likely to cause harm to the economy, environment or human health

    Naturalized – a non-native species whose introduction into the region can be identified and is reproducing naturally but is not acting aggressive or invasive in the landscape

    Endemic – a native species that is only found in one region or area
