Rare mustard

The ghosts of Junes past reminded me of a walk near the beach in the Asilomar state park of California. This is a nature reserve on a lovely beach near Pacific Grove in Monterey county. My attention was caught by a straggling little plant covered in wire mesh (featured photo). That led me to the discovery that this area was a protected micro-ecology, and that this tiny plant was a rare species on which protection effort is focused.

The four-petaled flowers belong to the Menzies wallflower (Erysimum menziesii). I saw it in its typical habitat: bare beach sand over which the salt sea spray would land now and then. I was lucky to see the flowers; they usually flower earlier. I could already see the fruits; the long flat bean-like things that surround the flowers. There are a lot of seeds there, so it is not clear why it is endangered. The answer comes in two parts. Most of the seeds are unable to grow into mature plants, and therefore they are out-competed by invasive plants. The conservation effort focuses on removing trampling hazard (for example by placing wire mesh over it) and by removing invasive plants by hand.

This is an enormous human effort, and brought home to me how skewed the global conservation effort is. A few hectares of California coastline probably get more economic and human help than parts of the Amazon basin which went up in flames last year. There are structural factors at play, and we should perhaps think about that as we decide which charity to donate to.
