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 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.

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.

The Atlas of Pelagic Seabirds off the West Coast of Canada presents maps that display the distribution of 48 species of seabirds and two species pairs (i.e., Red-necked and Red Phalaropes, and Hawaiian and Galapagos Petrels). Seabird surveys were conducted aboard commercial and Canadian federal government ‘ships-of-opportunity’ from 1982-1983 and 1991-2005 within the study area (45° N to 58° N and from the coast to 148° W). Sightings of rare species that came from other sources (including some pre 1982 and post 2005) are also included in order to present as complete a picture as possible. For 33 species and one species pair, the average densities within 5’ latitude by 5’ longitude grid cells are displayed seasonally.

This program is used to track Black Oystercatcher (Haematopus bachmani) population trend, local abundance, and annual survivorship. Bird banding, re-sighting visits and nesting population counts occur annually in the spring, with banding occurring in May to July since 2007, and nesting population counts occurring in late May or early June since 2008. The measurement for this species represents a complete annual census of birds nesting at key nesting locations across the park and is standardized across the three National Parks in the Coastal British Columbia bioregion with links to monitoring programs taking place in Alaska and Washington State. Completely dependent on marine shorelines for its food and nesting, these monogamous and long-lived birds establish well-defined breeding pairs and occupy composite feeding and nesting territories year after year, often along low-sloping gravel or rocky shorelines where intertidal prey are abundant.

The atlas provides maps and datasets representing seabirds at-sea densities in eastern Canada. Data were collected using ships of opportunity surveys and therefore spatial and seasonal coverage varies considerably. Densities are computed using distance sampling to adjust for variation in detection rates among observers and survey conditions. Depending on conditions, seabirds can be difficult to identify at the species level.

The second largest concentration of common terns (Sterna hirundo) in North America is found on Tern Islands, a set of three small barrier islands separated by water at high tide located within Kouchibouguac National Park. These seabirds are indicators for the condition of coastal, marine, as well as estuarine ecosystems due to the use of these nesting and/or breeding grounds, and their reliance on the distribution of small fish populations in lagoons or along the outer beaches of barrier islands throughout the breeding season. The purpose of the common tern colony monitoring program is to determine the annual total number of nests and estimate mean clutch size in order to evaluate long-term breeding population health. The methods for this measure involve an annual systematic census on Tern Islands over a 1-2 day period in mid-to late June during the late incubation stage.

This program captures counts of amphibian egg masses used to measure abundance and distribution trends in the breeding populations of Red-legged Frogs (Rana aurora) and Northwestern Salamanders (Ambystoma gracile) in the Long Beach Unit of the park. It is assumed that one egg-mass represents one breeding female. The Red-legged Frog is listed as a species of Special Concern (COSEWIC 2004). Surveys represent a complete visual census of selected representative lakes and wetlands (representing different wetland types, sizes and at variable distances from roads) and occur annually in the spring.

Monitor variations in seabird numbers and colony size in the St. Lawrence system. Survey of over 20 species of seabirds and herons during the breeding season, in order to monitor population dynamics through time and space. Seabird populations are influenced by food abundance and quality. There is actually more than 1,000,000 birds from more than 20 different species that breed in nearly 1,000 active colonies.

In partnership with ECCC, Gwaii Haanas monitors five Marbled Murrelet colonies by using a radar station located offshore. As birds fly out to the ocean at dawn, and return at dusk, the radar data is used to estimate the number of birds per hectare of suitable nesting habitat. Sampling areas focus on estuarine areas where the watershed or catchment contains old growth stands likely to host nesting birds in June and July. Marbled Murrelets are unique among seabirds because of their nesting habits – non-colonial nesting on thick, moss-covered limbs of large, old growth trees.
