Archive for February, 2018

This is a link to a blog post I wrote for the UC Davis-USDA Delta Region Areawide Aquatic Weed Project website. The Sacramento-San Joaquin Delta Conservancy (the agency I work for) gets funding from the USDA to control Arundo infestations in the Delta.

Arundo (which I have written about previously here) is a highly invasive plant that causes bank destabilization, increased fire hazard, increased water use, and excludes native plants and animals. The Delta Conservancy has been coordinating with a the Sonoma Ecology Center and the USDA to apply treatments of herbicides and/or insects that are specific Arundo parasites to eliminate Arundo from as much of the Delta as possible. This work began last summer/fall at the Brannan Island State Recreation Area, as site that is owned by California State Parks and which has a lot of Arundo.

This year, 2018, I have set up a little challenge for myself. The challenge is to see 100 or more species in Yolo County each month. Now, that does not mean that the 100 species of February have to all be different species from the 100 species in January. Rather it means that the total number of species seen in each month should get to a total of 100 or more. So, if I see a Red-tailed Hawk some time in January it gets added to the January list. If I see a Red-tailed Hawk some time in February it get added to the February list.

I am hoping this will help me to notice more details as I search to find that next species for a given month, encourage me to visit more habitat types each month, and highlight the seasonal differences as species come and go from my monthly list. I am looking forward to it, and will share what I see with you as the months go by.

To get started, below is my species list from January. It has a total of 105 species, so I made my target! It has some fun birds on it. The Cackling Goose that I found at Bridgeway Island Pond, and the Glaucous-winged Gull that I spotted flying over the Yolo Bypass were both very nice and unexpected additions. The Green Heron and White-throated Swifts were both surprisingly hard to track down. The fact that I never did find a Green-winged Teal was very unexpected as I figured that species would be a given in January.

Already, this challenge has been fun, and I have noticed myself checking each bird I see a bit more carefully just to make sure I don’t overlook that Lincoln’s Sparrow as yet another Song Sparrow and so deny myself a species. I think I am going to enjoy the rest of the experiment.

Here is my January species list.
