Monitoring Biology in Lakes

The following methods have been developed for assessing biological elements in lakes (please note that methods are under development):

 

Quality element

Method

Phytoplankton

<Composition (WFD38) RBPC1 (June 2007)>

<Bloom characteristics RBPC1 (Dec 2007)>

<Phytoplankton biomass [chlor] (WFD38) RBPC1>

Macrophytes

<Taxon composition and (relative) abundance of sensitive to non-sensitive species RBPC1 (Nov 2006) Leafpacs (Nov 2006)>

<Taxon composition and (relative) abundance of sensitive to non-sensitive species Free Index (Dodkins)>

< Taxon composition and (relative) abundance of sensitive to non-sensitive species CBass (ROI only)>

Phytobenthos

<Composition & abundance DALES RBPC1

<micro-algal tool N-S Share Project>

<macro-algal species identification tool N-S Share Project RBPC1>

<accelerated growth RBPC2>

<undesirable disturbance or balance of organisms RBPC1>

<bacterial tufts RBPC1>

Benthic invertebrates

<Composition & abundance RBPC2 N-S Share project>

<Ratio of disturbance sensitive to insensitive taxa RBPC1 N-S Share project>

<Diversity N-S Share project>

<Acidification (WFD60) RBPC1 (method Oct 2006) (classification late 2007-08)>

Chironomid pupal exuviae (CPET) RBPC1

Fish fauna

<Species composition (N-S Share) RBPC1>

<Species abundance (N-S Share) RBPC2>

<Type specific disturbance sensitive species RBPC2>

<Age structure of fish community RBPC2>

Species composition only (HIFI) RBPC2
