But in fact….

Descriptor 2: NIS introductions
“The tens rule” (Holdgate 1986, Williamson 1996).
“Beaufort Scale” for bioinvasion impacts?

Biopollution assessment – the concept
![Page 9: Anastasija Zaiko Anastasija.Zaiko@cawthron.org,nz · 2017. 11. 21. · Anastasija.Zaiko@cawthron.org,nz . Personal profile Background: PhD in ecology and environmental research Specialization:](https://reader035.fdocuments.us/reader035/viewer/2022062610/610e1b887c58ca56be596cef/html5/thumbnails/9.jpg)
Impact comparisons among species
![Page 10: Anastasija Zaiko Anastasija.Zaiko@cawthron.org,nz · 2017. 11. 21. · Anastasija.Zaiko@cawthron.org,nz . Personal profile Background: PhD in ecology and environmental research Specialization:](https://reader035.fdocuments.us/reader035/viewer/2022062610/610e1b887c58ca56be596cef/html5/thumbnails/10.jpg)
Impact comparisons among ecosystems
• BPL ranged from
“moderate” (BPL=2) to
“strong” (BPL=3)
• The highest scores - in
the coastal lagoons,
inlets and gulfs
• The highest number of
impacting alien species
(BPL>0, i.e. weak,
moderate and strong
impacts) - in the coastal
lagoons and inlets too

Challenge #2: test the response
![Page 12: Anastasija Zaiko Anastasija.Zaiko@cawthron.org,nz · 2017. 11. 21. · Anastasija.Zaiko@cawthron.org,nz . Personal profile Background: PhD in ecology and environmental research Specialization:](https://reader035.fdocuments.us/reader035/viewer/2022062610/610e1b887c58ca56be596cef/html5/thumbnails/12.jpg)
BQI response to eutrophication
Environment parameters BQI response
(coastal area)
BQI response
(plume zone)
Chl-a concentrations 0.75 (Acceptable) 0.56 (Poor)
(TP) concentrations 0.74 (Acceptable) 0.56 (Poor)
(TN) concentrations 0.70 (Acceptable) 0.87 (Excellent)
The steps denote proposed threshold values (strict
– 2.45, the most accurate – 2.56 and lenient – 3.05).
Numbers in brackets indicate specificity and
sensitivity values respectively.

Benthic quality and invasive species

Suggested index corrections
• Exclude species found
exclusively with zebra
mussels
• Exclude samples with
extremely high zm
abundances (>1000
ind/m2)
• Apply abundance
corrections for species
highly correlating with
zm

Challenge #4: set the targets

Framework for setting targets
Rossberg et al., submitted
• Define the natural
(pressure-free) range
of the indicator
• Define R: largest
acceptable time to
recovery (e.g. human
generation time)
THEN:
The target range – is the range of values from where
the mean time to reach the natural range (if all
pressures are removed) is <R
