Pine Rocklands Mangrove Sawgrass Prairie Hardwood Hammock More than One of the Above If Invasive, which of the following characteristics allowed it to become invasive? _____________________________________________________________________________________ 5
Biological Pollution Lab Worksheet Species: Intentional introduction Efficient reproduction Tolerance of a wide range of conditions Few or no natural enemies in the new ecosystem Ability to out-compete Able to colonize disturbed areas Clarify your above response: As stated above, they were originally brought from Australia to be used as wind breakers. However, they breed quickly and have accelerated their invasiveness in many different types of Floridian environments because of their tolerance for salt. They’re very efficient at reproduction and have to be managed, They tend to out-compete various native pines due to their deep root systems. _____________________________________________________________________________________ 6
