Final answer:
TDR programs are used in the Pinelands to control invasive species and preserve biodiversity.
Step-by-step explanation:
The TDR programs are used in the Pinelands to control and mitigate the expansion of invasive species such as Caulerpa webbiana. While the program may not completely eradicate the algae, it plays a crucial role in preserving local biodiversity and biotopes. The methods used in the program include the use of chemicals like chlorine and copper sulfide, and if the program continues, it would be necessary to monitor the potential contamination and ecological impact of these chemicals.
