Ecological Systems and Opportunities
April 2019

Project planning: how do we incorporate ecological values and issues?
1. Identifying regulatory issues: Fisheries Act, Species at RiskAct, Wildlife Act, Migratory Bird Convention Act, WaterSustainability Act.
2. Identifying important habitats or values that may not bespecifically addressed by regulation: rare ecologicalcommunities, freshwater wetlands, etc.
3. Identifying opportunities for creating or enhancing ecologicalvalues: from restoring ecological processes/systems to small-scale habitat improvements.
4. Identifying information gaps: Western painted turtle? Highwater line? Barn swallows nesting?
5. Listening to the community: sources of information,concerns, ideas.
Iona Island: summary of ecological values1. Iona Island is at the intersection of freshwater, marine, and
terrestrial ecosystems: intertidal marshes, mudflats,freshwater ponds, and coastal sand ecosystems.
2. River management and industrial use has disruptedecological processes but also created unique / novelecosystems.
3. Iona Island provides important habitat for migratory birds(freshwater & marine wetlands, shrub thickets, grasslands,forest).
4. Iona Island provides unique opportunities for to restorehabitat connectivity and ecological processes in the FraserEstuary.
5. Access to nature (birding) and recreation are also importantcultural values at Iona Island.
Historical vegetation (1860s) of the Iona Island area (from North et al., 1977). The light green colour (“g”) was indicated in the legend as ‘prairie: grasses’.

Interpreted ecological value (relative) of the Sensitive Ecosystems in Iona Beach Regional Park. All coloured areas are Sensitive Ecosystems; darker colours represent ecosystems of higher ecological value or sensitivity (map provided by Metro Vancouver Parks).
Iona Island is surrounded by critical intertidal habitats: marshes, mudflats, and tidal channels
