Checklist Comments

As predicted, the on-shore flow increased its influence overnight and the low clouds and fog layer extended further inland today. The fog disappeared pretty quickly (at least at the marsh), but the clouds persisted until Leo Ohtsuki and I were at Mason Regional Park at about 1030 or so. Leo and I did not cross paths at the marsh until about 0900. I looked at the “inside” ponds, of course, but mostly covered the “back 40” willow riparian areas, but also looked at most of the outer ponds (the old red-flowering euc row with myoporum understory at the northeast corner of the “L” shaped pond, but inside the water treatment plant, has been removed along with much of the existing vegetation inside the facility – what the hell?).
