Quercus tomentella

I have lived within an hour’s drive of Conejo Valley Botanic Garden for decades. How is it that I never visited until the other day? What a lovely place! What other nearby natural joys am I missing out on?

It was a delight to come upon an unfamiliar, yet local, oak tree, Quercus tomentella. This species is a relict. Though it is now limited to the offshore islands, it was once widespread in mainland California, as evidenced by the many late Tertiary fossils of the species found here. The tree in the gardens is young (planted 1995). All going well, it should grow two and a half times this high. Live long and prosper, Island Oak!

lizard comparison

With our local lizards having such variable colouration, telling them apart is more about shape and behaviour than it is about colour or patterns. Our most commonly-seen reptile is the western fence lizard, who loves to bask in the sun, gripping with long toes or doing pushups. Alligator lizards are seen less frequently. They have long, slightly prehensile tails and a snake-like way of slithering. Now that I’ve journaled the differences, I don’t think I’ll ever get them confused.

Pachygrapsus crassipes

Striped shore crabs (Pachygrapsus crassipes) live along the west coast of North America, from Baja California, Mexico, to central Oregon. Measuring 4 – 5 cm across the carapace, they can be found in estuaries, tide pools, mussel beds, or scuttling along shoreline rocks. These, and hermit crabs, are the most common crustaceans I see at my local tide pools.

Though they feed mostly on algae and phytoplankton, they are opportunistic and will also eat animals including dead fish, limpets, snails, isopods, worms, and mussels. They will even eat recently molted specimens of their own species. They are prey for seagulls, octopuses, rats, raccoons, and humans.

Though most crabs and many shore crabs spend the majority of their time underwater, P. crassipes is an exception. They apparently spend more than half their time on land, though they typically stay close to the water’s edge.

Panulirus interruptus

Spiny lobsters can produce a loud rasping sound by rubbing an extension of their antennae against a rigid part of their body below their eyes. This noise may be used to communicate with other lobsters or to ward off predators.

This was the most intact lobster shell I’ve ever seen at the beach. Sure, it was broken in half and was missing a few legs, but it was mostly there.

Schoenoplectus acutus

The wetlands in Legacy Park are alive with red-winged blackbirds, great-tailed grackles, mallards, coots and egrets. I like to sit by the tules and watch the interactions. Today there were a lot more drakes (9) than ducks (2); the females were getting persistently pursued and didn’t seem too happy about it.
