Panzner Wetland Field B, northern part. Locally dominant, in wooded wetland with carex, typha, sensitive fern. Most trees are juvenile, about 8cm dbh, 10m tall. I was surprised to find this species here, since it was not on the original delineation survey but is quite common.
My options are:
Salix gooddingii
Salix laevigata
Salix lasiolepsis
Too dense a vegetation to get closer for a better shot to ID beyond the genus, for me. The much lighter green of the under part of the leaves is intriguing.
Very tall (~30 feet), single trunk tree along Putah Creek in Winters, CA.
