Each Fall I create a unique limited-edition calendar containing some of my favorite images captured during the past year. I try to include a mixture of landscapes, plants, and animals and also try to match the image with the season as best I can. The calendar is printed single-sided on 8.5×11″ cover stock and is spiral bound at the top. I only print a small number of these unique calendars.
The 2017 calendar includes images from Florida and many special places around California, including Death Valley, Yosemite and the Eastern Sierra, and of course, the wild places on and around Mount Diablo.
Until a few years ago, the diminutive Mount Diablo Buckwheat wildflower (Eriogonum truncatum) was thought to be extinct. It had last been seen in 1936 by botanist and co-founder of Save Mount Diablo, Dr. Mary Bowerman, but hadn't been observed for the subsequent 69 years. Then in 2005 graduate student, Michael Park, discovered a small population of approximately 20 plants in Mount Diablo State Park. For the next 11 years, efforts to find additional populations in similar habitat were unsuccessful. In the spring of 2016 while performing a survey in the East Bay Regional Park District's Black Diamond Mines Regional Preserve, botanists Heath Bartosh and Brian Peterson noticed a steep hillside covered in pink. It turned out to be a second population of the Mount Diablo Buckwheat. The habitat was very different than the original site, and instead of 20 plants, they estimated 1.8 million plants present in this new location! I had the good fortune to photograph some of the plants in this new population - click the image below to view a small gallery.
Black-bellied Whistling Duck
Another trip to South Florida brought another visit to the Wakodahatchee Wetlands (see the January 2016 image of the month). Not surprisingly, things had changed in the six months since our last visit. Gone were the Palm Warblers that seemed to be in every shrub and tree. Purple Gallinules were also scarce. However, the Black-bellied Whistling Ducks were literally hanging out on the rails of the boardwalk allowing for close views (and photos) of their subtly beautiful plumage.
One of my favorite late spring hikes is the Mary Bowerman Trail near the summit of Mount Diablo. The hike is not challenging by any means - less than a mile in length and and level. However, the trail circles the summit and provides spectacular 360-degree views. Even better are the wildflowers that continue to bloom as the lower slopes of the mountain are entering their dry summer dormancy. While some of the flowers you find along the trail could have been observed in the lowlands earlier in the spring, others like this Bitterroot (Lewisia rediviva), are only found at the highest elevations of the mountain - Eagle Peak, North Peak, and the chert slopes along the Mary Bowerman Trail at the summit.
Mary Bowerman was a botanist who performed the pioneering studies of the flora of Mount Diablo starting in the 1930s. This trail that now bears her name was originally named the "Fire Interpretive Trail". It was constructed after fires in the late 1970s to educate visitors about fire ecology on the mountain. Mary was instrumental in ensuring that impacts to the habitat along the trail, especially these talus slopes and rock outcrops, were minimized during construction. She was also a co-founder of the conservation organization, Save Mount Diablo, and remained actively involved with the organization until passing away in 2005 at the age of 97. The trail was renamed in her honor in 2007.
After 4 years of drought the winter of 2015-2016, fueled by "El Nino"storms, brought abundant rainfall to Mount Diablo. The mountain responded with a spectacular Spring wildflower display. I captured this image of a Goldenbush, Lupine, and Paintbrush extravaganza on the slopes of North Peak during Save Mount Diablo's BioBlitz event.
