Update! Read this article from the Austin American Statesman on plans to help native trees and plants by removing invasive (non-native) trees, plants, etc.


Inasive Species - in this case, Ligustrum and Chinaberry
that Bull Creek Foundation volunteers cut during workdays.

Invasive Species - What are they?

Invasive Species are simply well adapted plants and animals that have been planted or moved to an area where they don't naturally occur. Due to a lack of constraints, such as fire, predators, human controls, etc - these plants and animals can grow and prosper unchecked. The down side to this is they outcompete or crowd out other native plants and animals.


Invasive Species - What does the foundation do?

We have put together a web page that describes the activities that the Bull Creek Foundation has undertaken in the Bull Creek Greenbelt and District park to control invasive species.


Invasive Species - Learning More

- We have an epidemic of non-native trees that we cut in the last year during volunteer trail workdays to let our native species grow back. Nearly all of these are Ligustrum, which really takes over. More on invasive species below. [9-Dec-03]

Here is a page of invasive species - trees and plants - that we remove when doing trail work - you should avoid planting these and remove any that you currently have - they overtake and crowd out our many native plants and trees.
Find out how to identify two of the invasive (non-native) trees that we remove the most: Chinaberry Tree and the Ligustrum. Find out more about other non-native, invasive plants and trees here.

The Union of Concerned Scientists has a excellent overview of Texas Invasive Species Issues - both plants and animals, on its website. [25-Sep-03]

Here are the non-native (invasive) species to the Central Texas area and their introduction crowds out native plants - trees and plants that we remove when we are doing trail and greenbelt work
