Steller sea lions jump from haulout -2

Steller sea lions jump into the Lynn Canal waters from the Gran Point haulout (second photo of three photo sequence). Steller sea lions often jump into water as a reaction to noise or movement.

Among the concerns related to the proposed Juneau Access Improvements Project is the Steller sea lion haulout at Gran Point (pictured). The haulout at Gran Point is a designated Steller sea lion Critical Habitat Area. According to the Alaska Department of Transportation’s 2014 Juneau Access Improvements Project: Draft Supplementary Environmental Impact Statement, more than one hundred Steller sea lions (Eumetopias jubatus) have been counted at the haulout during the spring and fall. As currently proposed the proposed highway would be built just uphill from the haulout area.

Highway plans near the haulout includes blasting steep rock-cut embankments and several tunnels with one tunnel entrance only 550 feet away from the haulout. There is concern for haulout abandonment by the sea lions during highway construction as studies have shown Steller sea lions are very sensitive to noise, both in and out of water. Because Steller sea lions frequent Gran Point nearly year round, the use of explosives and helicopters will be challenging during construction.

There are two distinct populations of Steller sea lions in Alaska. The majority of Stellar sea lions that frequent the Lynn Canal are part of the eastern population of Steller sea lions which are not listed as endangered under the Endangered Species Act; unlike the western population of Steller sea lions which are listed as endangered. That said however, there have been confirmed sightings of the western population Steller sea lions at Gran Point.

The Juneau Access Improvements Project is a proposed $570-million highway project to extend Glacier Highway out of Juneau for closer road access to the southeast Alaska towns of Haines and Skagway. Juneau’s roads do not connect with the continental road network.
