Valerie Vartanian, Horticulture and Landscape Professions Liaison

Valerie Increased global trade and travel are accelerating the spread of invasive species around the world. Invasive species (plants, animals, or pathogens) damage lands and waters, hurt economies and threaten our lives. West Nile virus, kudzu vines, and European starlings are all examples of species that have become established in the U.S. and are causing harm. Government agencies, land managers, businesses, and individual citizens are affected by the presence of invasive species. The cost has been estimated at $138 billion a year in lost productivity in the U.S.

The Nature Conservancy's Global Invasive Species Team works to prevent new invasions while containing established invaders. One of the major pathways for invasion by plants has been through gardens and landscapes. My role with the Global Invasive Species Team is to promote better business practices with the horticulture industry. I work directly with businesses and the private sector to change existing practices through voluntary actions and market incentives through a program called the Voluntary Codes of Conduct.

This program was developed by representatives from the horticulture industry and provides a set of guidelines which promote positive changes in business practices that screen out invasive plants and work to educate the gardening public. We are working with large and small businesses across the country. This voluntary program has been widely accepted as a positive, self-policing, process that the horticulture industry can implement effectively for a "win-win" result.

There is not a simple solution (or "silver bullet") to stop the spread of invasive species, but we believe we can make a difference working together (governments, businesses, NGOs, trade associations, etc.). Nurseries and other businesses can play a big role in how their industry steps up to battle invasive plants.

To achieve The Nature Conservancy's 2015 organizational goal, we must deal with invasive species (#2 global threat behind climate change). The Global Invasive Species Team is in a better position than ever before to help staff deal with invasive issues. We can provide insight, ideas, and tangible strategies that will work for country programs or other operating units. Often it is difficult for programs to figure out how to make a real difference on this global problem with limited resources, but if we work together the Global Invasive Species Team can help you incorporate strategies that will be more effective in achieving the 2015 Goal.

The Global Invasive Species Team has identified two key strategies related to invasive species:
  1. Prevent new invasions (e.g., Global Invasive Species Team staff dealing with policy and business practices), and
  2. Strengthen capacity of The Conservancy programs and partners to prevent and abate invasives (e.g., new strategic planning service and advice, tools and training).
My work as Horticulture Liaison involves both prevention by working directly with businesses to adopt new practices to reduce the spread of invasive plants and capacity building with operating units and country programs to share lessons learned and resource bases.

There are several ways in which I can help with your program.
  • Share what we are learning from other programs in the field.
  • Involve Conservancy staff with regional implementation of Codes.
  • Provide resource materials like alternative plant lists, presentation materials, and other invasive plant brochures.
  • Review plans, documents, or agreements/proposals to make sure they are consistent with current strategies.
  • Help you find a participating business that might help influence businesses in your region.
