A3.2-1a. Eelgrass Habitat Mapping and Distribution The data provided in the following table was collected in July and August 2003. Polygon numbers are listed in the first column. Zostera marina is checked under the heading Species Composition when the density equalled or exceeded 1 shoot per metre squared. Z. japonica is checked whenever the cover by this species exceeded 1%. An * is used to note presence of either species below these limits. The distribution of a species was considered continuous in cases where that species was distributed throughout the polygon, and patchy when the plants were confined to islands surrounded by either bare substrate or the other eelgrass species. The abundance of Z. japonica was classified as; present <1%, sparse <40%, moderate 41-75%, or dense >75%.

Residual Impact Assessment Evaluation criteria used for assessing the significance of the adverse environmental impacts of the project: Severity Rating for VECs (excluding marine mammals - partial matrix):

Magnitude Extent Frequency Duration Reversibility Severity Significance High Any Any Any Any High Significant* Moderate Regional or

Local Any Any Reversible

Low or Moderate

Regional, Local or Immediate

Any Any Irreversible

Moderate Non Significant

Moderate Immediate Isolated or Periodic

Short term Reversible

Low Regional, Local or Immediate

Any Any Reversible

Low Non Significant

*Impact significant if proper compensation and/or mitigation measures are not enforced Severity Rating for Marine Mammal VECs (partial matrix):

Magnitude Extent Frequency Duration Reversibility Likelihood Severity Significance High, Moderate or Low

Any Any Any Any High or Moderate

High or Moderate

Significant*

Moderate Regional or Local

Any Any Reversible Low

Low or Moderate

Regional, Local or Immediate

Any Any Irreversible Low

Moderate Non Significant

Moderate Immediate Isolated or Periodic

Short term Reversible Low

Low Regional, Local or Immediate

Any Any Reversible Low

Low Non Significant

*Impact significant if proper compensation and/or mitigation measures are not enforced

Appendix A4.1-1. Evaluation criteria for assessing significance ii

Severity Rating Definitions: Magnitude

High > 10% change in the amount of available habitat. Moderate > 5 – 10% change in the amount of available habitat. Low > 0 - 5% change in the amount of available habitat. Nil No change in fish habitat.

Extent

Provincial Effects extend outside of the regional surroundings, but within provincial setting.

Regional Effects extending outside of project boundary to regional. Local Effects occurring mainly within or in close proximity to the proposed

development area. Immediate Effects limited to the vicinity of the project.

Frequency

Continuous Effects continuous. Periodic Effects intermittent, but repeated. Isolated Effects confined to a specified period.

Duration

Residual Effects persisting indefinitely. Long-term Effects occurring after development of project, but diminishing with time. Short-Term Effects occurring within project development phase.

Reversibility

Irreversible Effects are not reversible and do not diminish with time. Reversible Effects are reversible and diminish with time.

Likelihood (Marine mammals only)

High Impact likely Moderate Possibility of impact Low Impact not likely

VEC: Marine mammals Marine mammals will not be affected by the footprint per se, and the effects of construction and operations are best summarized by impact source during these phases. Likelihood was also used as an evaluation criterion for marine mammals, as they are transient animals that may or may not be affected by impacts, depending on their location or presence within the local project area.
