Brenda Howard (CEH)
Centre for Ecology & Hydrology - Lancaster
27th – 29thJune 2012
Why are we giving these
courses?

Assessments are being done – little formal
training available

- so we don't assume much prior knowledge
We are being asked for advice on use of
assessment tools
 The tools are only recently developed and
there are various complexities and
assumptions which need to be understood


Assessment Tools


Some tools freely available and usable by others
Focus here on ERICA Tool (and its Integrated
Approach) developed by EC consortium
EPIC

RESRAD-BIOTA and R&D 128 mentioned when they
have features not present in ERICA Tool

Tiered Assessments

Many approaches use a tiered assessment
structure (in common with other areas of risk
assessments)


simple initial screening progressing to more
refined assessments if needed
Also referred to as:

staged or graded approaches
