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.

This program is used to determine juvenile salmonid population status and trends for Pacific Rim National Park Reserve. Surveys occur annually during the first two weeks of August and are focused on Coho salmon (Oncorhynchus kisutch) and Cutthroat trout (Oncorhynchus clarkii). Data are derived from in-stream salmon fry sampling by use of minnow trap at select streams in the Long Beach and West Coast Trail units of the Park with historical runs of salmon. Salmonid fishes act as an ecological process vector, connecting and transporting energy and nutrients between the freshwater environments, coastal forests and marine ecosystems.

Terra Nova National Park monitors intertidal invertebrate communities using a line transect and quadrat sampling method. The survey focusses on invertebrate community composition and diversity, and should detect presence of invasive marine species.

This program measures kelp density from annual dive transects during August and September at a number of sites in the Broken Group Islands of Pacific Rim National Park Reserve. Kelp species assessed include Agarum spp., Macrocystis pyrifera, Eisenia arborea, Pterygophora californica, Saccharina spp. and Desmarestia spp. Kelp forests are phyletically diverse, structurally complex and highly productive ecosystems in temperate rocky marine coastlines, thereby providing a suitable suite of measures indicative of subtidal ecosystem health.

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 aims to capture the extent of eradicated English Ivy (Hedera helix) and two species of invasive beachgrasses (European beachgrass/European marram grass (Ammophila arenaria) and American beachgrass (Ammophila breviligulata) relative to the total extent mapped in the Pacific Rim National Park Reserve. Areas of known or suspected distribution of invasive plants are mapped and treated as resources allow. The projects generally follow four phases: discovery, mapping, initial treatment (removal), followed by monitoring and additional treatments until the patch is free of the invasives. Our measure is assessed by comparing the area from which invasive plants have been removed to the sum of the area of occurrences mapped to date.

This project monitors water quality at 14 sites (streams and lakes) within the Long Beach Unit of the Park. A total of 46 water quality parameters are recorded at each site twice per year (spring and fall), including concentrations of nutrients, metals, and physical properties. The thresholds applied to the data are standards prescribed by the federal or provincial government for freshwater aquatic life and overall water quality is ranked based on the annual average CCME WQI (Canadian Council of Ministers of the Environment Water Quality Index). This measure is used to report and act on issues related to water quality and water pollution in the park from external sources, answering the important questions of: (1) Is water quality, in selected streams or lakes of the Long Beach Unit, within set water quality limits for aquatic wildlife as determined from concentrations of anthropogenically generated contaminants and (2) Is the overall water quality within the specified quality bounds?

This program aims to monitor migratory shorebird abundance, distribution and use on sandy beaches of the Long Beach Unit as an Ecological Integrity condition measure and to monitor the effectiveness of management activities directed at increasing the rate of compliance with domestic animal (leash) regulations as a management effectiveness measure. These datasets result from annual migratory shorebird surveys, during which birds passing through a 100 m section of beach over the course of 30 minutes are counted as are the disturbance events affecting them. Sites (n=20) are surveyed throughout the day (between 6am and 6pm) during the height of spring (20 April to 25 May) and fall (15 July to 1 Oct) migrations and are surveyed 4 to 8 times per migration period per year. It is well-established that migratory shorebirds operate on very tight time and energy budgets and that unexpected loss of time and/or energy reserves can compromise both survival and breeding success of these birds.

From the point of view of ecological integrity and the responsibility of the park to protect and maintain a biotic community naturally associated with the ecoregion, we are primarily interested in the extent of two land cover classes, the old-growth forest, which should not decrease in the park, and the artificially cleared areas or the anthropogenic footprint, which should not increase. This program measures the extent of old-growth forest and tracks changes in the land cover class (measured in 30x30m grid cells) to the baseline year (1990). We use land cover datasets derived from remotely-sensed satellite imagery of the park to capture forest-stand replacement events, which in our case are due to construction-related clearing or natural stand-replacing events (e.g. windthrow from storms).

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.
