Uplift meadows & parkland

Raised former tideland

On glacially rebounding sites throughout northern Southeast, lush herbaceous meadows of variable width on recently elevated tideland begin just above extreme high water. The meadow surfaces are generally well-drained and eventually succeed to forest. But as long as uplift continues at a more rapid pace than world sea-level rise, new uplift meadow will be created from tidal marsh as fast as it is lost to advancing forest.

During the Juneau Wetlands Management Plan Update Project, 2014-2015, the Bosworth field team assessed forested and floodplain wetlands, fen/marsh, and lush wet meadows, all on former tidelands in this area.
