I visited on a warm, clear day in March to enjoy all the new green growth and buzzing and humming of insects everywhere. This is the first of three posts showing what I saw.
Turkey vultures were enjoying the thermals above Blue Ridge:
California poppies had started to adorn the hillsides in February, but were carpeting them in March, especially on the southwest facing slopes:
Regrowth was lush at the base of the California buckeye at marker A07 (map):
I’ve been watching the new stalks of California laurel at B03 get progressively taller:
New, though, was this interesting growth of stalks at the base of a much larger California laurel (not at a CA Phenology Project at Stebbins marker):
Cold Creek clear and full:
Although the reserve remains closed to the public until May, there have been large numbers of trespassers. Evidence comes in the form of paths blazed down to the creek off the main trail:
This activity directly interferes with the reserve’s ability to fully recover from the fire by increasing erosion and damaging newly regrown plants. Plenty of other evidence of trespass too:
I returned to the reserve in February excited to see how much greener it would be and whether any wildflowers were starting to appear. This drawing of Blue Ridge shows a dramatic difference from a month and a half prior:
All along the creek trail, I enjoyed the new greens, as seen in the new growth below in a California buckeye and the Toyon at marker A02 (markers are used by the CA Phenology Project at Stebbins; here is a map of the marker locations).
Cold Creek was running higher, and the water and the sediment both look cleaner than they did on my December and January visits.
And there were wildflowers! Not all that many yet, but I did see Henderson’s shooting star (Dodecatheon hendersonii), Henbit (Lamium amplexicaule), Large-leaved hound’s tongue (Cynoglossum grande), Blue dicks (Dichelostemma capitatum), Miner’s lettuce (Claytonia perfoliata), and Wild cucumber (Marah fabaceus).
High-intensity chaparral fires cause increased erosion and sediment transport into streams, and this can be seen in the thick black sludge filling the Cold Creek channel. On my December visit, with no recent rain, the creek bed was pretty dramatically full of sludge.
December 30, 2015:
By my January visit, several small storms had contributed to small flows in the creek. As water washes the runoff from the burned hillsides through the system, ash from the fire as well as contaminants that were present on the hillsides will move through Cold Creek and into Putah Creek. This creates water quality concerns which will be addressed by future water quality monitoring to be conducted by the Solano County Water Agency.
