Addressing Invasive Plant Species in California
Why are we here?
Landscape-level management
needs for sharing spatial data
Doug Johnson
, Executive Director, Cal-IPC
We’re here because we care about...
Wildlife
Recreation
Infrastructure
Agriculture
Water
Fire
And therefore we care about...
Diseases
Animal pests
Aquatic weeds
Rangeland weeds
Mussels
Forest pests
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
Spatial Data
Required in order to be strategic at any
scale.
Presence
Absence
Suitable range
Spread
Sources of Data
Where does data come from?
Field mapping
Volunteer observations
Remote sensing
Expert knowledge
Data-Sharing
Builds on an existing resource to
allow strategic management at the
landscape level
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
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.
Our goals today
Learn from each other
Synthesize a
document
with agreed-upon:
- principles
- recommendations
The challenge:
•
200 invasive plant species
•
Entire state of California (100 million acres)
•
Need spatial prioritization for early eradication
and strategic containment
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

How important is it to plan landscape-level
strategy across western states for
addressing invasive plants?
Conclusions of the 2016
WWCC Meeting:
1.
Everyone is committed to sharing data
2.
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

Executive Director Doug Johnson of Cal-IPC discusses the challenge of 200 invasive plant species across California's vast land, requiring spatial prioritization for eradication and containment. The solution involves aggregating digital datasets, collecting expert knowledge, assessing priorities based on distribution, and using range modeling to predict spread. Funding sources and strategies for utilizing phone apps, email alerts, prioritization, management tracking, and more are also outlined.
