On Wednesday, Thursday and Friday there will be some of the highest tides of the year in San Francisco Bay, so I’m going to look for the northern ssp. of saltmarsh harvest mouse and the black ssp. of ornate shrew at Lower Tubbs Island on Friday. Vagrant shrew and San Pablo Bay ssp. of California vole have been seen there during the previous king tide, and other interesting mammals and birds (such as Ridgeway’s and black rails) are possible. If you’d like to meet there and look together, you are welcome. The high tide will be at noon, but it takes more than an hour for the water to fill the marshes, so plan to stay at least until 1 pm. The trail description is here; it’s usually better to use a bicycle, but the trail might be too muddy this time. Walking from the trailhead to the marsh (the loop part of the trail on the map) takes a bit over an hour. The weather forecast is fairly good so far.
UPD: I’ll be going there on Friday, not Wednesday. Sorry, family obligations.
