Prof. Samuel Fitzgerald, Ph.D.People engage in active work during their daily activities, intended to reduce the dispersal of non-native species. Boaters implement Clean-Drain-Dry methods proliferated by the state natural resource departments in between waterways. Gardeners select native plants for their gardens instead of choosing non-native ornamental species or ground covers. Pet owners utilize animal surrender programs instead of releasing animals into the wild. Travelers declare agricultural items when crossing land borders. All of these actions, together, provide an effective barrier against the major pathways of introduction.
Boaters & Anglers
- Clean-Drain-Dry: Remove all mud and plants before leaving access points
- Inspect trailers: Check for hidden snails or plant fragments
- Report sightings: Use USGS Nonindigenous Aquatic Species app
- Certification: Complete state-approved watercraft decontamination training
Home Gardeners
- Plant natives: Choose local species instead of invasive Barberry or Burning Bush
- Soil inspection: Sterilize potting mixes to kill weed seeds
- Disposal: Bag invasive clippings don't compost
- Alternatives: Swap Butterfly Bush for native Buttonbush attracting pollinators
Pet Owners
- Surrender programs: Use rehoming services like Habitattitude
- Never release: Goldfish grow to 16 inches damaging ponds
- Microchipping: Required for high-risk species in 28 states
- Education: Attend responsible pet ownership workshops
While focusing on Everglades restoration programs, I was able to document how public action can lead to a measurable impact. For example, when boaters reported seeing unusual snails, remediation efforts for zebra mussel containment were initiated. Gardeners removed invasive vines and replaced them with native coral honeysuckle, thereby helping to restore bird habitat. Pet surrenders decreased the likelihood of creating new colonies of pythons. Each of these actions is undertaken at the individual level and collectively contributes to the protection of ecosystems.
Reporting tools provide a focus for individuals and communities to engage with rapid response systems. Refer to EDDMapS for terrestrial plant sightings and the USGS NAS database to report aquatic species. I have witnessed reports lead to "containment" on-site within 24 hours, preventing the establishment of the invasive species reported. Encourage travelers to declare fruits and seeds, using the USDA declaration forms. Your observational and reporting skills represent the first line of defense against biological invasions.
