Invasive plants represent a major threat to the Delaware River watershed, displacing native plant communities, destroying wildlife habitat, degrading the wild and scenic beauty of the landscape, altering natural processes, and disrupting recreational activities.


In August 2000, representatives of a number of private organizations and government agencies met to discuss strategies for reducing the negative economic and ecological effects of invasive plant species in the Delaware River watershed. The Delaware River Invasive Plant Partnership (DRIPP) was formed to increase public awareness and understanding of invasive plants and their impacts, facilitate the exchange of information regarding invasive plant management, and help coordinate public and private efforts to control these weeds in the Delaware River watershed.


The major goals of DRIPP are:

1)     to unite private citizens, organizations, and academic institutions with local, state, and federal agencies working to control invasive plants in the watershed;

2)     to develop an overview of what is known and what is being done about invasive plants in the watershed;

3)     to create a comprehensive invasive plant management plan that includes thorough inventories of invasive plant species, identification and prioritization of the most problematic invasive plants, and best practices for control and management of these weeds;

4)     to coordinate watershed-wide invasive plant control efforts, train volunteers in inventory and control techniques, and develop a rapid response system to combat new invasions, and

5)     to increase public awareness and understanding of the impacts, prevention and management of invasive plants.


Freeing the Delaware River watershed from the burden of invasive plants will help maintain its healthy and diverse native plant and animal communities and permit it once again to boast the finest views and recreational opportunities.
