Animals from a variety of elevations and habitats can be observed in
the park.
On the Pacific coast, and especially near the mouth of the Nalychevo River,
one can observe seals, most often larga seals (or motley seals) during
salmon spawning season, as well as Steller's sea lions and sea otters.
In the central part of the park, situated 340 meters above sea level,
visitors will greatly appreciate sightings of the Kamchatka brown bear.
The bear population in the park has remained stable as of 2004, numbering
124 individuals. One to five bears can be observed right from the cabins
of the central camp during the berry season almost daily from August 10
to September 20. The animals feed in the tundra, most often in the morning
and evening, in their customary places along the right bank of the Goryachaya
River. Bears rarely visit the left bank of the river, where the visitor
cabins are located (though 2005 was an exception when, because of poor
salmon runs, bears behaved abnormally all over Kamchatka). From the end
of September through October, bears fish on the river, often under cover
of flooded groves of thickets.
The Kamchatka sable is observed less frequently than bears, but it can
be seen all the same during the day, both in the forest and in dwarf pine
thickets. Females raise their young in summer, and hunt even in daylight.
More than 300 sables reside in the park, and that number has increased
in recent years.
In twilight hours in summertime, the Brandt bat can be observed near the
cabins and hot springs as it hunts for insects.
The river otter and American mink are rather numerous in park and can
be observed any time of the year.
The Eastern Siberian lynx came to Kamchatka relatively recently, having
dispersed onto the peninsula from the continent. The lynx first appeared
in Nalychevo Park around 1960. Usually hares are the lynx's main prey,
but as with many animals on Kamchatka, the lynx has learned to hunt salmon,
and can successfully catch fish in the water after spawning. Unlike many
cats, lynx are good swimmers. Lynx can be observed in Nalychevo Park in
winter and in early spring, albeit infrequently; however, their tracks
on the snow in winter are often noted along the banks of small spawning
streams.
While searching for fish, lynx often use trails laid by wolverines along
the rivers. The wolverine prefers to spend the summer (the breeding season)
in the mountain tundra or elfin woods, but as winter approaches, it descends
to the forests and tirelessly explores large distances scavenging for
food.
Kamchatka wolves can also fish in shallow water and therefore visit small
spawning streams. Tracks of individual wolves near the cabins of the park's
central camp and on the floodplain of the Goryachaya River can be found
in October or November.
The fox does not breed in dens in the central part of park, but comes
here only for short periods in late autumn and in spring each year.
In the mountains, at an elevation of 600-1,500 m above sea level, visitors
often observe the amusing and not timid Kamchatka ground squirrel.
Permanent colonies of black-capped marmots are found in the park in the
crater of the Dzendzur Volcano, in the spurs of the Kupol Volcano, and
at the foot of Avacha Volcano.
The snow sheep inhabits the park in two isolated populations. One group
inhabits the environs of the Dzendzur-Zhupanovsky volcanic massif, and
the other lives by the sea on the cliffs of Cape Nalychevo. While successful
breeding of snow sheep has been documented, the overall numbers of sheep
have decreased in recent years.
According to available information, a herd of fewer than 20 wild reindeer
deer inhabits the territory of the park.
The English names of mammals in the park can be found in "The Catalogue
of Vertebrates of Kamchatka and Adjacent Waters".
