Citizen Scientists Publish Sea Otter Discovery

In Biological Monitoring, Featured, Research, Salt Marsh, Sea Otter, volunteering by Administrator

Citizen scientists at Elkhorn Slough Reserve have discovered that sea otters spend a surprising amount of time napping on salt marshes. Most research on southern sea otters comes from the rugged open coast of California, because they recovered from a tiny population off Big Sur.  Elkhorn Slough is the first estuary to be thoroughly colonized by sea otters, and volunteer researchers found they behave quite …

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.

Shorebird Waterfowl and Waders Monitoring Research

In Biological Monitoring, Bird Monitoring, Birds, Research by Administrator

Description of monitoring Twice each spring and fall during peak migration, volunteers identify and count shorebirds, waterfowl, and waders at low tide during timed watches at four defined areas of Reserve wetlands and adjacent areas. Surveys are carried out by boat (from the main channel) and land.  (An additional site is also surveyed at high tide). The experience is challenging …

Shorebird and Waterfowl Monitoring Research

In Biological Monitoring, Bird Monitoring, Birds, Research by Administrator

Past shorebirds and waterfowl monitoring in and around Elkhorn Slough (1989-2000) Over the last several decades, various shorebird and waterfowl monitoring has been carried in and around Elkhorn Slough. From 1989-2000, for example, Sue Shaw faithfully recorded all shorebird and waterfowl seen during her regular visits to measure water quality at 24 stations. The stations were located along the entire …

Raptor Monitoring Research

In Biological Monitoring, Bird Monitoring, Birds, Research by Administrator

Elkhorn Slough Reserve hosts a variety of breeding raptors. In a typical year, there may be 2 pairs of white-tailed kites, 1 pair of red-tailed hawks, 1 pair of red-shouldered hawks, and 4 pairs of barn owls. These top carnivores are often good indicators of ecosystem health: if they fail to reproduce successfully, this may be the result of pesticide accumulation …
