To maintain its continuity, a municipal forest should have trees of all ages with a preponderance of them young. Annual plantings ensure that younger trees are in place to replace aging ones, and the benefits of the forest, whether shade, clean air, blossoms, fruit, autumn color, or psychological balm may be enjoyed by city dwellers without interruption. Imagine the reverse: if all trees were the same age, a significant portion of the canopy would be lost by old age alone. Only volunteers would be left to carry on.

What’s the first thing you think of when I say Humboldt? If you’re from California you could be thinking of the county, college, bay, fort, state park or wildlife refuge. If you’re from Nevada you might think of the river, the national forest, wildlife area, sink, saltmarsh, lake, mountain ranges, county or creepy ghost town. Dewy-Humboldt in Arizona, Humboldt Illinois, Humboldt Kansas, Humboldt Iowa, Humboldt Ohio, Humboldt Wisconsin, Humboldt Saskatchewan, it’s hard to escape Humboldt. Humboldt is everywhere. The Humboldt name graces multiple mountains and mountain ranges, forests, national parks, waterfalls, glaciers, an ocean current. and a giant sinkhole Animals and plants including, penguins, squid, bat, monkey(s), skunk, snail, an entire genus of flowering plants, legumes, endangered cactus, a beetle, river dolphins, a carnivorous plant, oak, orchid, lily and mushroom all bear his name. Humboldt is in outer space, the Mare Humboldt on the moon and two asteroids bear the name. That doesn’t even touch the organizations, institutions, monuments and other random things that are all called Humboldt.
The orchid family, Orchidaceae is enormous, containing 28,000 species. That’s just slightly more species than the population of Monterey, California. The species count does not include the 100,000 or so cultivars that have been bred by humans. California has only 31 native orchids (most of them live in the tropics). I didn’t realize that I had seen my first one.
