1. Landscape-level management needs for sharing spatial data
Why are we here?
Landscape-level management needs for sharing spatial data
Doug Johnson, Executive Director, Cal-IPC

2. We’re here because we care about...
Wildlife
Recreation
Infrastructure
Agriculture
Water
Fire
Why do we care about invasive plants? Not only do they degrade wildlife habitat, they also degrade ecosystem services we all depend on, from food and water to roads and recreation.

3. And therefore we care about...
Diseases
Animal pests
Aquatic weeds
Rangeland weeds
Mussels
Forest pests
Why do we care about invasive plants? Not only do they degrade wildlife habitat, they also degrade ecosystem services we all depend on, from food and water to roads and recreation.

4. Management Must be strategic:
Capacity - we need to get the most out of whatever we put our limited resources toward
Effectiveness – only way to get on top of the problem

5. Spatial Data Required in order to be strategic at any scale. Presence
Absence
Suitable range
Spread

6. Sources of Data Where does data come from? Field mapping
Volunteer observations
Remote sensing
Expert knowledge

7. Data-Sharing
Builds on an existing resource to allow strategic management at the landscape level

8. We’re here because… We want to be effective at the landscape level
Mapping and data sharing are critical
We want to strengthen mapping and data sharing by working together

9. Principles we (may) agree on
To be fully effective, invasive species management requires:
landscape-level action, which requires...
landscape-level distribution data, which requires…
aggregation of distribution data.
We may also benefit from more attention to…
collection of expert knowledge distribution data.

10. Our goals today Learn from each other
Synthesize a document with agreed-upon:
- principles
- recommendations

12. The challenge:
200 invasive plant species
Entire state of California (100 million acres)
Need spatial prioritization for early eradication and strategic containment

13. The solution:
Aggregate all existing digital datasets
Collect “expert knowledge” to fill in the gaps
Assess priorities based on distribution
Add range modeling to anticipate spread

15. Landscape-level projects
$400K (state)
$300K (federal)
$150K (foundation)
$100K (federal)
$75K (federal)
$25K (state)
$400K (state)
Regional on-the-ground projects are a top focus. Cal-IPC has worked with local partners to secure funding for early eradication work in several regions of the state, as shown on the map. Most of the weed work on the ground is being implemented by county Agricultural Departments.
We also have funding applications in the pipeline for additional projects, both on-the-ground early eradication projects as well as planning projects to set up on-the-ground projects. Many of these are seeking to use Prop. 1 water bond funds, which brings some particular challenges.
$90K (federal)
$400K (state)
$25K (state)

16. South Central Coast Eradication Project
$400K 5-year WCB grant to RCD
Bond funds - eradication
5 target species:
Canada thistle
Dalmatian toadflax
Algerian sea lavender
Japanese dodder
Russian wheatgrass

18. What mapping features do you use?

…plus ODA models weed habitat suitability.

19. How important is it to plan landscape-level strategy across western states for addressing invasive plants?

20. Conclusions of the 2016 WWCC Meeting:
Everyone is committed to sharing data
EDDMapS is the logical aggregation site
Basic data fields are all that’s needed
Coarse resolution is fine
Sensitive data needs to screened out
Absence data is important
