I’m having one of those expat moments today, and find myself feeling a little homesick for my own native habitat of the California coast, so I thought I’d write about one of my favorite trees that grows only there. The rarest known wild pine tree in the North America is the Torrey Pine (Pinus torreyana), which grows exclusively on a small area of the coast north of San Diego, and in a small grove on one Santa Rosa Island, one of the Channel Islands.

Although it has been theorized that the tree’s range once extended up the coast as far north as Oregon, by the time the tree was described in 1858 by botanist John Torrey (for whom the tree is named), there were less than 300 individual trees found during the course of the Mexican-American Boundary Survey which had gathered the samples.

It’s a tree adapted to very harsh conditions in the wild. Slow-growing, it sends its tap roots exploring through the clefts and cracks of cliffs where there is very little dirt. A small seedling can have a 2-foot (60 cm) root, an adult tree of 60 feet (19 m) can have a tap root three or four times that length. The large pine cones take years to mature, and the tough pine nuts dropped on to the ground only gradually and over a period of years – these are too indestructible to be eaten by most birds,  can be viable for up to ten years, and in an unprotected habitat, would best burst into germination only after being cracked by a  fire. The tenacious adaptations of this tree to a dry, coastal environment are part of what make it so fragile in the wild.

The tree was named the Solitary Pine by early Spanish explorers, but during the course of the late 19th and early 20th centuries, the pine rooted itself in local lore. Rather than being commercially and residentially developed as all of the neighboring lands were, this small coastal area found supporters who wanted to preserve the tree and its habitat. I have little doubt that without this intervention, the Torrey pine would be another extinct species we would read about but never see in the wild.

The Torrey pine is widely planted in southern California, but the ornamental and cultivated trees often look quite different from the preserved wild ones found in Torrey Pines State Natural Reserve. The cultivated trees are tall, straight and have rounded heads, while the wild trees are smaller, with the crooked, windswept forms that make them so memorable. At least, for me.

Chula Vista means something like ‘cool view’ and that’s what San Diego Port authorities and environmentalists had in mind when they fought for the demolition of the 1950s power plant relic located on the shores of Chula Vista, California. The eyesore was taking up prime bayside real estate, and was blocking the cool view, both of the wetlands area on the California coastline, and of the real estate and development potential of the land. The plant pumped out 700 megawatts of power an estimated 5800 tons of emissions into the air every year. It started out using oil as fuel, and later switched to natural gas, supplying power to 40% of San Diego County.

“Demolishing the power plant with a single implosion will expedite creation of an unobstructed view corridor for the residents of Chula Vista and moves us closer to creating a world-class resort and residential destination on our portion of San Diego Bay as outlined in the Chula Vista Bayfront Plan,” said Mayor Cheryl Cox, quoted in a local newspaper article. The project, costing about $60 million, will generate an estimated 21,000 tons of recyclable metals, and another 3,400 tons of non-hazardous waste, such as wood and plastic. I was unable to find any mention of the amount of hazardous waste removed, although some articles mentioned asbestos.

A large wetlands renovation project is underway to try and undo some of the damage caused by the power plant, as well as other long-term human impact. After all, this power plant is located near a large military installation, one of California’s largest cities, and a large port.

I’m sure when it was built, it was seen as an indispensable boon, both in terms of power supply and employment – a large stride into the future, powering a modern city from the shores of a bay that was already under heavy development. With the exception of a few beachcombers and birdwatchers, I’m sure few people would have argued its value or relevance. Fifty years later, it’s a poorly placed, outdated, inefficient toxic eyesore.

So, when I think about the ongoing development of criteria for sustainable power generation that are (in theory) more environmentally sensitive while still being both efficient and profitable, I wonder this: Which of these criteria that we currently consider acceptable, or relevant, or indispensable will, in fifty years, be judged with the same critical eye and dismay we now cast upon the defunct Chula Vista plant?
