Criteria |
|
|
|
|
Likelihood of transfer |
Not likely, due to extensive testing and
surveillance and strict protocols to prevent transfer |
Low, several
management practices and disease testing and surveillance is done |
Moderate, some risk reduction measures, but testing is incomplete (i.e.
not on all bait species) |
High, no routine testing of bait species, not
able to be detected visually |
Prevalence in bait supply |
Has not been found in MN bait supply |
Low
prevalence in bait supply, 1-33% |
Moderate prevalence in bait supply,
34-66% |
High prevalence in bait supply, 67-100% |
Colonization potential |
Not likely, organism will not be established
due to climate mismatch, life cycle limitation or lack of suitable hosts |
organism has a low probability of becoming established on the basis of
climatic, life cycle, or host requirements |
Organism has a medium
probability of becoming established on the basis of climatic, life
cycle, or host requirements |
Organism has a high probability of
becoming established on the basis of climatic, life cycle, or host
requirements, or has been introduced in some areas of MN |
Current distribution in MN |
Common, frequently encountered, widespread |
Fairly common, either widespread but not abundant in any location or
abundant in some areas |
Uncommon, not widespread or abundant in any
location |
Not Detected, surveys have been conducted but the organism
has never been found |
Economic impact |
No known impact on any game species, fishery, tourism
or species of interest |
Mild impact on economic contribution of game
species, fishery, tourism or species of interest |
Moderate impact on
economic contribution of game species, fishery, tourism or species of
interest |
Severe impact on economic contribution of game species,
fishery, tourism, or species of interest |
Ecological impact if established |
No or negligible impact on
population, community, or ecosystem ecology |
Mild ecological impact
(e.g. minor shift in food web) |
Moderate ecological impact (e.g. some
habitat degradation, some food web impact, etc.) |
Severe ecological
impact (e.g. fishery collapse, cascading effects, habitat degradation,
etc.) |
Host species |
No known hosts in MN or single non-game, non-threatened
& endangered (T&E) or management-relevant species affected |
Single
game, T&E, or management-relevant species affected |
More than one
game, T&E or management-relevant species affected |
Several game, T&E
or management-relevant species greatly affected (i.e. high
mortality) |
