Mountain fire revisited

I returned to a small wash area I visited twice earlier this summer, once about a week before the Mountain fire, and again about a week after. Some rain fell in the area in July and early August; not enough to wash the abundant ash back into the soil. Nonetheless there are many signs of recovery. Most of the chaparral shrubs are adapted to fire and showing excellent signs of recovery. No annual seedlings were present with a possible exception of these small sennas; they may also be sprouts from perennial roots, though. Hard to call. I suspect they are S. bauhinioides though S. covesii is also found in the area.

One interesting note: Aristolochia watsonii seemed positively abundant. More likely, it was just more visible due to the loss of all ground cover.

I specifically looked for this single individual Thelypodium wrightii, but there's no sign of it. It was growing within a dense copse of mixed chaparral species and not easy to get to for the photos. The copse is much easier to navigate now.

This wash area, though included within the perimeter of the 2005 Bart fire, did not burn at that time. The plants were quite mature prior to the Mountain fire.

List of chaparral perennial species showing good signs of recovery:

Amsonia palmeri
Cercocarpus montanus
Krameria erecta
Nolina microcarpa
Quercus turbinella
Rhamnus ilicifolia
Simmondsia chinensis
Tragia ramosa
