Press Release: Elkhorn Slough Researchers Link Salt Marsh Dieback to Algal Blooms Generated by Increased Nutrients

In Press, Research, Salt Marsh by Administrator

The study reveals that piles of green algae form mats along bank edges that leads to dieback of the salt marsh below. When the marsh plants die, the roots no longer help to hold the bank together causing large pieces of the bank to fall into the channel in response to strong tidal currents or wind-driven waves in the slough.
