Recently, it was announced that the California Department of Fish and Wildlife caught folks poaching Dudleya farinosa from coastal Mendocino and Humboldt counties. The tip came in from a Postmaster who noticed dirt spilling from a box being shipped to China. Conversations started, one post office talked to another, and they realized poachers were moving from post office to post office shipping boxes of the charismatic Dudleya farinosa. One of the postal workers then reported the suspicious activity on CalTip and this is now an active international poaching case.
This neatly wrapped Dudleya was confiscated by Game Wardens before it left Humboldt County on its way to Asia’s thriving succulent market. Fifty volunteers soon replanted them on the steep hillside cliffs they call home.
I spoke with Cliff Berkowitz on KHUM’s Happy Trails about places to visit–starting now–to explore spectacular Humboldt County wildflowers. Flowers start flowering early because of the temperate nature of the region. This means that you can find wildflowers starting in January near the coast, all the way to June and July inland in our mountains.
Green plants are considered autotrophs because they photosynthesize—making sugar from water and carbon dioxide. The world of heterotrophic plants is complicated but all have moved away from total energy production from photosynthesis toward obtaining organic carbon either directly from other living beings or through a parasitic relationship with a fungus. Heterotrophic plants include directly parasitic and mycotrophic forms. The conifer forests of the western United States nurture an exceptional diversity of heterotrophic plants.
The main event has been on the calendar for the past eight years. I have heard stories from friends who have actually traveled around the world to see the phenomenon–and from that alone I knew if there was and eclipse practically in our backyard, we needed to go. We selected a spot in the heart of the Ochoco National Forest and literally on the edge of the Mill Creek Wilderness in a meadow complex. The Mill Creek Wilderness Twin Pillars Trail was our hiking destination the day before the eclipse event. The wilderness protects a harsh environment typified by ancient lava flows, fire-prone conifer forests, and the Mill Creek Drainage itself. We found wonderful views across central Oregon and a fire-scared landscape on our way to the Twin Pillars. In addition, western larch (Larix occidentalis), was the conifer highlight on this adventure.
Most botanists are familiar with the ecological similarities between the southern Appalachians and the Klamath Mountains. These two regions are the two most bio-diverse temperate regions in North America. Here is as excerpt from Conifer Country:
I have begun a collaborative mapping and inventorying project for yellow-cedar in California this summer. The species is a CNPS Inventory of Rare and Endangered Plants on list 4.3 (limited distribution) in the state, with only a handful of known locations. The majority of the stands are on the Klamath National Forest but a few are also on the Six Rivers. Over the course of the summer I will be visiting a number of these populations and collecting data on stand health, reproduction, and plant associates. I made the first stop of the summer at the Bear Peak Botanical Area.
This is the last of my four posts about Santa Rosa Island. It is simply a photographic tour of plants that have not yet been highlighted in previous posts including other interesting, rare, endemic, and common Santa Rosa Island plants.
Santa Rosa Island Plant list I generated from CalFlora
The first time Santa Rosa Island landed on my plant exploring radar screen was when I learned about the Torrey pine some time in the early 2000s. I had never even seen this tree until I took a trip to Torrey Pines State Reserve north of San Diego in early 2012. It is the rarest pine in North America with several thousand “mature” trees on both the mainland and island. My bucket list for understanding the ecology of this species is complete now that I have visited the island.
As mentioned in an early post, pigs were first introduced on Santa Rosa in the mid 1800s. By 1888 it is estimated, based on historical records, that there were only 100 Torrey pines on the island. Today, all herbivorous megafauna have been removed (minus 5 sterile horses from the old ranch) and the Torrey pine are thriving–with an estimated 12,300 trees–one-quarter of which are saplings!
Researchers debate the arrival time of the Santa Rosa Torrey pine, estimating anywhere from 6,000 to over 1 million years. Disagreement also exists as to whether these two population represent subspecies or varieties of each other. Some argue the two populations are genetically different enough to be considered a subspecies, others prefer distinction at the variety level. Regardless, it is a beautiful species and well worth seeing in the wild.
We passed five Orcas (Orcinus orca) on the passage to Santa Rosa Island
After a two hour boat ride from Ventura Harbor that included sightings of gray and killer whales, passengers disembarked onto a newly-built pier and subjacent white sand beaches. We had arrived. Once unloaded, the park ranger offered an orientation rejoicing in our good fortunes. The high winds and thick fog which had typified the previous few weeks had now subsided. The forecast for the coming days included sun, low winds, and perfect temperatures.
Fog and wind are omnipresent on Santa Rosa Island and play a major role in shaping the landscape. Any plants with a propensity for upward growth are restricted to canyons, particularly north sloping ones. Here they find refuge from the wind and often more available moisture provided by the meager 15-20 inches of annual rain. However near the highest island peaks–like Black Mountain at 1,300 feet plants have adapted to wind and fog in different ways.
