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.

  1. What an exciting learning opportunity it is to visit the Farallones! Is there a way to see your photographs larger? I click on them and they open to ones the same size. It looks like such an interesting place.

  2. Hi Eric,
    It is an amazing place. We will try to make the pictures larger from now on…we are still working out some of the kinks. I will work on thumbnails that expand to a a larger photo.
    Thanks for your interest and keep checking back, I am about to upload some more photos.

  3. I was thinking of you “guys” out there as I was beachcombing on Ocean Beach today.

    Today’s photos are incredible especially those of the sea creatures in Jewel Cave. I am so envious! ;-)
