Grow Native! Don’t Plant a
PestA public outreach campaign from the Arizona Native Plant Society
The Arizona Native Plant Society is a statewide nonprofit organization devoted to Arizona's native plants. Its mission is to promote knowledge, appreciation, conservation, and restoration of Arizona native plants and their habitats.
1. Are not from other ecosystems.
2. Cause economic or environmental harm as they spread!
INVASIVE, NON-NATIVE SPECIES
Animals and Microbes can be Invasive Non-Native Species,
too!

IMPACTS of INVASIVES
•FIRE
•Crowding out of native vegetation
•Sense of place, economic values
Saguaros & other
desert plants and
animals are not
fire-adapted

TAKE HOME MESSAGES
1. Proportion of ornamental exotics doubled in 22 years as they spread from the nearby housing developments.
2. Longer a species is present, the more likely it will become invasive
Natural areas are becoming increasingly vulnerable to urban landscaping
Grow Native! Don’t Plant a
Pest• Identify ornamental plant species that are invasive in southeastern Arizona wildlands
• Present native alternative species (alterNATIVES)
Featured invasive ornamentals were chosen based on:known impacts to wildlands
transparent scientific assessments
use in southeastern Arizona landscapes
Featured AlterNATIVES were chosen based on:
Current availability in the nursery trade
Similar in:– Appearance– Function– Life history
