Garden edges: former imperial property borders freeway on one side, harbor on other side

浜離宮恩賜庭園には、長い歴史と面白いカモ猟の場所があります。さらに、都市と湾の端の思いがけない風景があります。

Hamarikyu is an elaborate garden between the office towers of Shiodome and the harbor full of warehouses, garbage incinerators, and the massive immigration office with no cellphone coverage. Inside the garden, you can learn how the Emperor created a special landscape to facilitate duck hunting that used decoy ducks, falcons, and nets. But on the edges of the garden, you can see the messy metropolis with its relentless accumulation of transportation, commerce, and recently new luxury residential development. I like how on the city side, the stone-lined canal has been preserved, and on the harbor side, an older looking flood gate still regulates the garden’s pond.

Live video of falcon nest on downtown San Francisco office tower

Wow! San Francisco’s gas company (Pacific Gas & Electric) has set up a live webcam so you can the peregrine falcon nest on top of their downtown office tower. Four chicks were hatched on April 8 and 10.

What a cool way to support wildlife in the city and the popular interest that sustains urban habitats. The project is a partnership with UC Santa Cruz Predatory Bird Research, and there’s a Yahoo discussion group.

Meeting Yamada Yoriyuki at Kajima

Recently I met with Yamada Yoriyuki (山田順之), Manager of the Office of Global Environment at constructino company Kajima and a leader in bringing biodiversity ideas to Japanese corporations. He showed me the new interactive illustration Kajima created of an integrated sustainable city, where bees pollinate community gardens, school fields are mowed by goats, falcons provide crow control, rivers support animal life, hospitals have healing gardens, and plants and animals contribute to a better environment.

Yamada’s vision for new urbanism is holistic, with the widest variety of wildlife improving human life. Contrary to the government’s minimal regulations, Yamada boldly states, “I am not interested in greening.” Instead of applying green to existing projects, Yamada emphasizes habitat and culture. Habitat requires links between insects and birds, bees and food, trees and birds, clean water and fish. As an anthropologist, I was also pleased to hear Yamada emphasize culture as key to creating social change in cities. Yamada cites the importance of “eight million kami” (ya-o-yorozu no kami or 八百万の神), a Shinto belief in animism and the presence of spirits in an infinite number of natural beings and materials.

In addition to working with Kajima and the Japanese Business Initiative for Biodiversity, Yamada is very hands-on. He explained how he monitors honeybees on Kajima’s Ikebukuro dormitory using GPS and biking along a 2 kilometer radius. From his observations, he sees urban honeybees avoiding park and street trees because pesticides have made them unsafe, and preferring instead small gardens grown by residents.

Yamada also cites the Japanese Pygmy Woodpecker as a key indicator species. Because it travels relatively short distance, urban habitat requires a series of interconnected parks and street trees creating a green web. I find this idea of the ecological connection between large public spaces and individual gardens very inspiring.

I also highly recommend the article he co-authored: Kumagai, Yoichi and Yoriyuki Yamada. “Green Space Relations with Residential Values in Downtown Tokyo: Implications for Urban Biodiversity Conservation.” Local Environment, Routledge Press, Vol. 13, No. 2, 141–157, March 2008.
