This set of data contains the results of the various breeding seabird inventories conducted at Forillon National Park. Seabirds are recognized as good indicators of the quality of marine ecosystems and more particularly of the abundance of prey species on which they depend. Monitoring of seabird populations is therefore part of Forillon National Park's ecological integrity monitoring program. The abundance of different seabird species is determined by a total nest count in the cliffs during the nesting period.

This program captures the relative abundance and distribution of five common seabirds occurring in the waters of Pacific Rim National Park Reserve including the Marbled Murrelet (Brachyramphus marmoratus), Common Murre (Uria aalge), Rhinoceros Auklet (Cerorhinca monocerata), Pigeon Guillemot (Cepphus columba), and Pelagic Cormorant (Phalacrocorax pelagicus). The at-sea surveys are done approximately every two weeks from May to September and use standardized fixed-route strip transects to estimate annual variations in the population of seabirds using the near-shore waters of the park. Seabirds are prominent members of the inshore marine ecosystems and are considered to be sentinels of both local and broad environmental change. The demographic stability of seabird populations may serve as an integrated measure of health of the shoreline ecosystem.

This program assesses demographic parameters and breeding abundance of 5 species of ground (burrow) nesting seabirds: Pigeon Guillemot (Cepphus columba), Rhinoceros Auklet (Cerorhinca monocerata), Glaucous-winged Gull (Larus glaucescens), Leach's Storm-Petrel (Oceanodroma leucorhoa) and Fork-tailed Storm-Petrel (Oceanodroma furcata) at the Seabird Rocks Colony through population counts and capture-mark-recapture techniques. Counts of individuals at the colony are done 3-4 times throughout a breeding season (May-July) to estimate the size of the breeding populations. A banding (capture-mark-recapture) program to estimate annual survivorship of the two storm-petrel species is done via mist-net arrays on two consecutive nights in early May and/or mid-to-late July. This project seeks to track the present status of the ground and burrrow-nesting seabirds on Seabird Rocks and any recovery that may occur due to future habitat restoration and/or predator-control measures.

Study area is a polygon feature class showing the extent of where most of the bird sightings were recorded and then used in the atlas. A few rare species have been included as well that go beyond this area.

Grids surveyed is a polygon feature class containing the 5’ latitude by 5’ longitude grid cells surveyed for all seasons combined including the grids that were surveyed but where no species were seen. In order to produce maps for a specific season a selection for these grids must be performed.

Gwaii Haanas has partnered with ECCC to monitor a set of permanent plots mapping colony structure and burrow occupancy rate by excavating samples of burrows of Ancient Murrelet and Cassin’s Auklet. The data are used to determine if the breeding population areas are changing at specific key nesting colonies and if the change signifies an increasing or decreasing population trend. An estimated 1.5 million seabirds breed colonially on the 200+ islands, islets and rocks of Haida Gwaii, including globally and nationally significant proportions of 5 seabird species. A significant threat to breeding seabirds is predation by non-native mammals, notably raccoons and rats.

Polygons denoting concentrations of sea pens, small and large gorgonian corals and sponges on the east coast of Canada have been identified through spatial analysis of research vessel survey by-catch data following an approach used by the Northwest Atlantic Fisheries Organization (NAFO) in the Regulatory Area (NRA) on Flemish Cap and southeast Grand Banks. Kernel density analysis was used to identify high concentrations and the area occupied by successive catch weight thresholds was used to identify aggregations. These analyses were performed for each of the five biogeographic zones of eastern Canada. The largest sea pen fields were found in the Laurentian Channel as it cuts through the Gulf of St. Lawrence, while large gorgonian coral forests were found in the Eastern Arctic and on the northern Labrador continental slope.
