This dataset covers the census of pinnipeds (harbour and grey seals) that frequent the waters of Forillon National Park. Grey and harbour seals are two top predators in the food chain of the park's coastal ecosystems; hence the importance of monitoring these populations. Surveys are conducted by boat along the coasts of Forillon National Park and on the periphery in calm weather and at low tide when seals are present in large numbers on resting and calving grounds.
A first dataset covers inventories from 2007 to 2015. The inventory covers three specific periods: during the calving and nursing period for harbour seals (May-June), during the moulting period for harbour seals (late July - early August) and when grey seals are present in large numbers (mid-August). At least two boat trips are planned during each inventory period. The stage of maturity of the individuals surveyed is recorded, as is the type of activity observed (on the beach or in the water).
A second dataset covers inventories from 1977 to 2000. Depending on the year, the inventory can last a few days or even several weeks, from spring to fall. The stage of maturity of the individuals surveyed is recorded, as is the type of activity observed (on the beach or in the water).
