We started monitoring again at Oak Openings on April 29.
Without Ruta it will be more difficult to identify some of the plants - such as this Lyre-leaved Rock Cress.
At least that's what we think this is (above and below).
It is in the mustard family. Unfortunately, they look quite similar and there are several common ones blooming now.
Here is a plant none of us needs help recognizing. It is Bird Foot Violet and a favorite of us all. The leaves look like birds feet. It likes disturbed sandy soils and is doing well this year.
We don't monitor Wild Oats, but they were growing near the Bird Foot Violet. I don't remember seeing them there before.
