Title: River to River CWMA: Addressing the Issue of Invasive Plants in Southern Illinois


1
River to River CWMAAddressing the Issue of
Invasive Plants in Southern Illinois
  • Christopher Evans,
  • River to River CWMA Coordinator

2
Outline
  • What is a CWMA
  • River to River CWMA
  • Area
  • Members
  • Goals
  • Invasive Plants
  • Definitions
  • Problems
  • CWMA species
  • Solutions

3
What is a CWMA?
  • Cooperative Weed Management Area
  • Collaborative effort between multiple agencies
    and organizations to coordinate efforts and
    programs for managing invasive plants
  • Well-defined area counties, watersheds, regions
    etc.
  • Different scopes one species, suite of species,
    habitats, etc.

4
Cooperation is Key
  • Conservation can be achieved only be the
    cooperative efforts of agencies, organizations,
    and individuals across the nation.
  • - Natural Resource Conservation Service
    Strategic Plan 2005-2010

5
River to River CWMA
  • Formally established in 2006
  • Coordinator hired in April, 2007
  • Address terrestrial and aquatic non-native
    invasive plants in Southern Illinois

6
11 Southernmost Counties in Illinois
  • Alexander
  • Gallatin
  • Hardin
  • Jackson
  • Johnson
  • Massac
  • Pope
  • Pulaski
  • Saline
  • Williamson
  • Union

River to River CWMA Goal
  • Work cooperatively in inventorying, monitoring,
    controlling, and preventing the spread of
    non-native invasive plants across jurisdictional
    boundaries in the 11 southern counties in
    Illinois.
  • - RTR CWMA Memorandum of Understanding, 2006

10
River to River CWMA Goal
  • By coordinating our efforts, we can
  • Reduce the costs and time of management
    activities
  • Manage across boundaries
  • Pool available resources
  • Increase the chances of success
  • Better detect/prevent new introductions
  • Better raise public awareness about invasive
    plants
  • Prioritize issues

Need for Cooperation
  • There is a bountiful seed source of many of the
    exotic/invasive species on the lands surrounding
    the Refuge, thus in order to be effective in our
    management plans, we must bring together a
    complex set of interests including private
    landowner, commercial, and public agencies.
  • - Crab Orchard National Wildlife Refuge
    Comprehensive Conservation Plan, page 24

16
Invasive Species
  • Not native to Southern Illinois
  • Introduced
  • Ability to reproduce in the wild
  • Potential to spread and cause economic or
    ecological damage
  • Loss of species diversity
  • Loss of ecosystem functions
  • Loss of productivity
  • Loss of wildlife habitat

17
Loss of productivity
  • Bush honeysuckle invasion leads to a decline in
    the growth rate of trees by over 50
  • - Hartman and McCarthy 2007

Troy Evans, EKU
18
Invasive Species
  • New habitat is free of natural predators,
    parasites, and diseases
  • Often gives exotic plants a competitive edge over
    native species
  • Can readily invade disturbed areas due to
  • High seed production
  • Quick maturation time
  • Efficient methods of seed dispersal
  • Allelopathic effects of some invasives?

19
Allelopathy
  • Some plants give off chemicals through their
    roots that kill/inhibit other plants

20
Allelopathy
  • Garlic Mustard release chemicals from its roots
    that kills the native micorrhizal community
  • Native plants depend upon micorrhizae to help
    absorb nutrients from the soil
  • Even after garlic mustard control, recolonization
    of the site by micorrhizae may be slow
  • Restoration efforts hampered

21
Invasive Species Damage
  • Invade and occupy space before native species can
    colonize
  • Grow over, crowd, or girdle native species
  • Cast heavy shade and form dense monocultures,
    limiting the ability of native plants to grow
  • Close-in open areas
  • Limit animal and human movement through an area
  • Limit recreational activities
  • Overwhelm seedbanks
  • Once the invasive is cleared, only new invasives
    come back

22
Invade and occupy space before native species can
colonize
Autumn olive and sericea lespedeza invading old
roadbed
23
Grow over, crowd, or girdle native species
Kudzu overwhelming a hardwood forest
24
Cast heavy shade and form dense monocultures
Japanese stiltgrass forming a solid mat of
vegetation
25
Close-in open areas
Bush honeysuckle invading an opening in a savanna
restoration
26
Limit animal and human movement through an area
Multiflora rose thorns a serious deterrent to
anything trying to travel through an infested area
27
Limit Recreational Activities
Curly leaf pondweed infestation, reducing the
ability of anglers to fish
28
Overwhelm seedbanks
Rosettes of garlic mustard, showing domination of

Other species we do not know about?
Abundance
Time
31
Other species we do not know about?
  • Need for an Early Detection and Rapid Response
    (EDRR) System
  • Any new or suspected invasive species is reported
  • Identification/threat is verified
  • If so, necessary steps are taken to eradicate or
    contain infestation

32
Which is Easier to Control?
33
Need for Control and Management
  • Exotic and invasive plant species pose one of
    the greatest threats to the maintenance and
    restoration of the diverse habitats found on the
    Refuge.
  • - Crab Orchard National Wildlife Refuge
    Comprehensive Conservation Plan, page 24
  • Eradicate, control, and prevent the introduction
    of invasive exotic species
  • - One of six primary challenges set forth at the
    beginning of the Illinois Department of Natural
    Resources State Wildlife Action Plan

34
Need for Control and Management
  • Non-native invasive species must be controlled
    or eradicated.
  • - Shawnee National Forest, Land and Resource
    Management Plan
  • We control invasive species because they are
    harming the native plants and animals we care so
    much about protecting.
  • - The Nature Conservancy Global Invasive
    Species Initiative website http//tncweeds.ucdavi

37
Prevention
  • First line of defense and the most cost
    effective strategy against invasive species
