Grey seals (Halichoerus grypus) are distributed along the entire northern Murman coast in Russia. Breeding sites are located mainly on the Ainov and Seven islands, which belong to the Kandalaksha Nature Reserve. The annual pup production was estimated to be around 800 pups in the early 1990s, and the pup mortality has been observed to be relatively high. The population was estimated to be approximately 3,500 individuals in 1994. Grey seals migrate in small numbers into the White Sea during summer. The grey seal is protected and registered in the Red Books of Russia, Murmansk region and Fennoscandia. The main results of grey seals investigations from 1986 to 2000 are briefly reviewed. There are no recent studies on abundance, seasonal distribution, growth, moulting and feeding of the species.

Pup Mortality

During the period September-December in 2001-2003, ship based surveys of grey seal (Halichoerus grypus) pups, including tagging, counting and staging of pups, were conducted along the Norwegian coast. All known and other potential breeding areas were surveyed from Rogaland county in the south to Finnmark county in the north. Most of the breeding sites were surveyed only once, but some sites were surveyed 2-4 times. The investigations resulted in a total minimum estimate of 1,159 grey seal pups born in Norwegian waters. Nordland county was the most important breeding area where about 50% of the pups were born. Total population estimates were derived from the recorded number of pups born using a range of multipliers (4.0-4.7), based on observed annual growth rates of approximately 7-12% in other grey seal populations. This gave a total estimate of about 5,800-6,600 grey seals including pups in Norwegian waters. However, the total pup production was probably underestimated due to only one pup count in most of the breeding sites. Observed mean pup mortality was 1.1% during the breeding season along the Norwegian coast.

Harbour Seals

Grey seals (Halichoerus grypus Fabricius) and harbour seals (Phoca vitulina L.) have been surveyed on the coasts of Iceland since 1980. During the period 1980-2012, both seal species have declined markedly in numbers at the Icelandic coast. The grey seal has established a considerable breeding site on the northern spit of the Surtsey island. This is at present one of the biggest grey seal rookeries on the southern shores of Iceland, with estimated about 60 pups born there in the autumn of 2012. On the other hand, the harbour seal has not been numerous on Surtsey during breeding time in the summer. Breeding sites of harbour seals on the south coast of Iceland closest to Surtsey are in the estuaries of the glacial rivers Ölfusá, Þjórsá, Markarfljót and Kúðafljót. Harbour seals, however, haul-out in great numbers on the northern shores of Surtsey during the winter, presumably using the island as a resting place after foraging in the adjacent waters.

The first annotated list of mosses of the planned Kaita Nature Reserve with 139 species and 1 variety was compiled. Rare species (Leucodon sciuroides, Philonotis caespitosa, Schistidium apocarpum, Sphagnum annulatum, Sphagnum inundatum, Splachnum rubrum et al.) have been found. One species (Orthotrichum speciosum) is listed in Red Data Book of the Murmansk Region (Krasnaya…, 2003). Half of the recorded moss species often occur throughout the Murmansk Region. The lists of mosses of the planned Kaita Nature Reserve and two neighboring protected areas (Lapland and White Sea part of Kandalaksha Strict Nature Reserves) were compared.

The Atlantic Grey Seal, Halichoerus grypus, is one of the world's rarer mammals. In 1954 R. M. Lockley estimated its total population as 33,500 and there is no reason to suppose there has since been an increase. About 20,000 of these seals live in colonies around the coasts of the British Isles, all on the north and west, except for one colony which inhabits the Fame Islands, a National Trust nature reserve off the Northumberland coast.
