Alien Owlet Calls

Moonlight bouncing off fog banks between Butano Ridge and Long Ridge.

Owlet with your silly call, some type of cross between a tweet, a whistle and a screech.  When your parents patiently coach you with their hooo hooo ho-hoo ho-hoo, I can usually find them in the dark.

Scales on My Sleeve

A California mountain kingsnake in hand.

I found a California mountain kingsnake while checking the main springbox at the ranch.  As the rainy season ends, we've unclogged pipes, replaced filters and sealed a leaking water tank.  The spring slows down to a trickle in the summer, so its unnerving to start the dry season without a full water tank.  When we found a valve mistakenly closed in our water system, I started systematically checking all the essential parts.

Sierra Azul Open Space Preserve - Wildflower Hotspot #4

Sierra Azul Open Space Preserve - Woods Trail and Barlow Road

Above the town of Los Gatos, my favorite trails in the 17,600-acre Sierra Azul Open Space Preserve are Woods Trail and Barlow Road.  These connected trails are interesting and botanically diverse because together, they carve a 360-degree circle below Mt. Umunhum in open grassland, chaparral and shady forests with rocky outcrops and small headwater streams.  You get to see many different types of vegetation and most wildflowers are presented to you right alongside the trail, even at eye level.  There is one location along Barlow Road where I often see  red larksur (Delphinium nudicaule, shown above) growing shoulder to shoulder with a deep purple larkspur.

Moving in Straight Lines

Handsome thighs of a California red-legged frog

I took a workshop last week on the California red-legged frog.  The classroom portion covered biology and behavior, and the day and nighttime field portions covered habitat, life stages and pouncing on frogs under the careful guidance of the certified instructors.  By 10:00 pm of the nighttime training, we were all basically returned to our childhoods. The boys were counting up how many frogs they'd captured, and the girls were wondering why they were following boys around in the woods at night.  Once I took my gloves off, my frog capture rate went up to about 80%, but I preferred the spotlighting duty of being the first to detect the alien-eye-rays bouncing from the willow thicket back to our strategically aimed flashlights.

Almaden Quicksilver County Park - Wildflower Hotspot #3

Almaden Quicksilver County Park

Almaden Quicksilver County Park is located in south San Jose around the former mining town of New Almaden.  Here you get a view of nature reclaiming the mined lands with several of the park entrances right out of residential neighborhoods.  A dreamy afternoon can be spent reading about the wild ways of the New Almaden mining days in the first chapters of Wallace Stegner's Pulitzer Prize winning book, Angle of Repose, and then hiking further into these very same hills.  Or you can just go the Almaden Quicksilver Mining Museum after your hike.

Trails wind through open stands of valley oak and blue oak trees with Chinese houses, farewell-to-spring and other colorfully-named wildflowers waving in dappled light, and California quails calling from mossy rocks and crumbled brick foundations.

Edgewood Park and Natural Preserve - Wildflower Hotspot #2

Edgewood Park and Natural Preserve, Redwood City, California

Edgewood Park and Natural Preserve balances on the edge of San Francisco's suburbs and the rugged, undeveloped mountain valley that stores water for the 2.5 million humans living along the Golden Gate and San Francisco Bay.  Once it was scarred by motorcycle trails and destined to become another golf course.  But a stubborn group of local botanists kept finding small, unusual plant treasures there and reversed the fate of this county park.

Edgewood Park is the most consistent and reliable place to see the spring wildflower display in the Santa Cruz Mountains and it can be easily reached from any city between San Francisco and San Jose by taking Edgewood Road east from Highway 280.  Highway 280 is sometimes described as one of the most beautiful highways in the world, and in addition to the darkly forested slopes to the west often crowned by great banks of cascading fog, the bright patches of Edgewood wildflowers to the east are likewise visible from the highway each spring and subtly remind the speeding motorists that they are following the course of a major faultline between two giant sliding landforms.

Coyote Ridge - Wildflower Hotspot #1

As you travel on Highway 101 between San Jose and Morgan Hill, you may have noticed bright patches of spring color on the hills to the east - this is Coyote Ridge.  Serpentine rock, part of our unique California fault-shaped geology, forms Coyote Ridge and soil high in some minerals and low in plant nutrients.  Some California plants have evolved to be tolerant of these conditions.

Poor soils often make for good wildflowers.  Coyote Ridge supports a colorful spring bloom of wildflowers including more than a dozen rare species.  It is also one of the few remaining habitats for the threatened bay checkerspot butterfly (Euphydryas editha bayensis) which is dependent on a few small native plant species for adult nectar and caterpillar forage.  Increased deposition of nitrogen from the air, probably primarily from automobile exhaust, is changing the unique soil conditions that create the serpentine grasslands and is allowing European annual grasses to spread on Coyote Ridge and outcompete the colorful native color that also supports the rare butterfly.

Wildflower Hotspots of the Santa Cruz Mountains

On cloudy days, some flowers stay closed.

I will be making a presentation Wildflower Hotspots of the Santa Cruz Mountains on Sunday, April 24, 2011 from 11:00 to noon at Mission College in Santa Clara, California for the 39th Annual Wildflower Show of the California Native Plant Society - Santa Clara Valley Chapter. Below is my list of 20 wildflower hotspots. Each has a link to the park website with directions, trails and other logistics.

Many generous local plant people have nominated their favorite hikes and allowed me to use their wonderful photographs which I will be sharing at the show.  Over the next few weeks, I will be posting some of those photos here with more details on spring hikes, giving you tips on how to find and enjoy wildflowers and providing links to some of these great photographers.  Go to the "Search This Blog" window in the middle of the right-hand column and enter "wildflowers" or "hikes" to find the updated posts about wildflower hikes.  Please add your observations and check the comments for the most recent information.
