Morning Day Two-12 November 2009

The low tides are in the afternoon this week, so we spent our morning on a steep granite hillside helping the refuge management get rid of the invasive New Zealand Spinach.  The spinach is a non-native plant that competes with the native Farallon weed (with yellow blooms above). The hundreds of thousands of seabirds that breed on the Farallones use the endemic (found only here) Farallon weed as nesting material.  The roots of the spinach hold on to more soil than the native plants and compact the soil, making it harder for seabirds, that lay their eggs in burrows.  We climbed as high as we could and enjoyed the spectacular views.
