- Ensure
that invasive potential is assessed prior to introducing and
marketing plant species new to North America. Invasive potential
should be assessed by the introducer or qualified experts
using emerging risk assessment methods that consider plant
characteristics and prior observations or experience with
the plant elsewhere in the world. Additional insights may
be gained through extensive monitoring on the nursery site
prior to further distribution.
|
- Work
with regional experts and stakeholders to determine which
species in your region are either currently invasive or will
become invasive. Identify plants that could be suitable alternatives
in your region.
|
- Develop
and promote alternative plant material through plant selection
and breeding.
|
- Where
agreement has been reached among nursery associations, government,
academia and ecology and conservation organizations, phase-out
existing stocks of those specific invasive species in regions
where they are considered to be a threat.
|
- Follow
all laws on importation and quarantine of plant materials
across political boundaries.
|
- Encourage
customers to use, and garden writers to promote, non-invasive
plants.
