In addition to the 6-acre Wigeon Ponds property acquired in 2010, SEAL Trust has acquired 8 other properties along the Mendenhall Peninsula through 2015 (see map below). All of these properties are accreted wetland marsh that were once part of the Mendenhall Wetlands State Game Refuge. The properties provide both high and low marsh habitats that are critical for waterbirds, songbirds, and raptors. Designated as a globally significant “Important Bird Area,” the Mendenhall Wetlands support 255 bird species with the majority being migrants. In addition to habitat for birds, the wetlands on these properties provide a) groundwater recharge and discharge, (b) sediment and toxicant retention, (c) nutrient transformation and transport. All three properties are adjacent to Casa del Sol Creek, which is an anadromous stream supporting Coho, Chum, and Dolly Varden salmon.

Excellent walking and birding is available on these properties, but under a CBJ ordinance, hunting is not allowed. The properties can be accessed from a public trail off Mendenhall Peninsula Road.
