Invasive Species

• 1) alien to the ecosystem under consideration and
  
• 2) whose introduction causes or is likely to
  cause economic or environmental harm or harm to
  human health. (NISC 1999)

The IM Focus
Early Detection
To monitor each of 10 sites of ecological
significance in KLMN that are currently weed-free
every year for the next 15 years to detect
incursions of the Networks top 10 invasive
plants.

Portland Meeting (PWR)

• Early detection protocol status of the science
• 8 key steps
• RFPUSGS Status and Trends
• Pilot projectKLMN
• (with broader application).

8 Steps to Optimum Early Detection

• Step 1. Develop a list of target species
  resources. Prioritize.
• Step 2. Assemble known information.
• Step 3. GIS risk of occurrence model (using Step
  2).

10
8 Steps to Optimum Early Detection (cont.)

• Step 4. Develop an optimal search strategy
  (survey design).
• Step 5. Use search model to direct search
  efforts.
• Step 6. Record results and provide feedback.

11
8 Steps to Optimum Early Detection (cont.)

• Step 7. Analyze and report results.
• Step 8. If one of the target species is found and
  cannot be controlled immediately, make
  arrangements for control efforts.

12
Selected USGS Proposal

• Edwards et al. (Utah State)
• (1) Develop statistical models linked to a GIS
• (2) Identify the micro-site characteristics
  necessary for the establishment of an invasive
  species and

13
Selected USGS Proposal

• Edwards et al. (Utah State)
• (3) Examine the adequacy of the models for
  predicting the likelihood of occurrence of
  invasives.
• Covers steps 2-6.
• April 2005-September 2006

14
Coordinating the Other Steps

• Prioritization process
• Rapid response system coordination IM, EPMTs,
  Fire, Maintenance, Interpretation, etc.
• Latham, Geissler, Sarr, Welch, et al.

15
Thoughts to Ponder

• How can we adapt the current IM Data Management
  Plan to address rapid response issues (e.g.,
  invasive species)?
• Whats the IM role in a reporting network?

16
What You Can Do Now!

• Inventory / survey IS
• Define objectives
• Gather ancillary information
• Prioritize species
• Prioritize conservation issues
• Relevant to ALL IS monitoring!

17
Other USGS Early Detection Efforts

• Dorazio et al. imperfect detection
• Smith et al. adaptive sampling / incidental
  reports
• Caldwell et al. remote sensing

18
Other NPS Efforts

• GLKN GIS-based predictive model
• COPL early det., efficacy, etc.
• LAME
• GOGA
• SFAN
