Expedition: Rezanof Lake

SCS traveled with Forest Service personnel investigating the decommissioned cabins in Maksoutoff and Rezanof lakes. We conducted invasive and sensitive plant surveys on both Rezanof and Khostof lakes, including the main creek valley at the head of Rezanof Lake and up the northwestern slope of Mt. Hagemeister.

We did not locate any invasive plant species in the area.

The most unique vegetation type encountered on this trip was the grass dominated meadows on the eastern shore. The grasslands may be maintained by episodic flooding and/or browse of invading shrubs and trees.

Also at the upper lake shore were less frequently encountered species such as Symphotrichum subspicatum. An infrequently encountered orchid (on Baranof Island), Goodyera oblongifolia, was found in the peninsula between the Khostof and Rezanof lake.

We did relocate populations of Mimulus lewisii (on the Alaska Natural Heritage Vascular Tracking List) on the eastern shore of Rezanof Lake.

We found one adult boreal toad in the sloughs of Rezanof Creek.

Rarely documented lichen (for Baranof Island) on Tsuga mertensiana on Mt. Hagemeister: Nephroma arcticum

Historical: Located USGS markers related to hydrological project in late 1960's.

Range extension of a bryophyte, Pseudolescurea patens, previously known from Yakutat area in Southeastern Alaska.

Notable bird sightings: Great Blue Heron nest, Red Tail hawk, Lesser sandpiper, and Red throated loons.
