Oh, was it so? From a story one former city official wrote about Citizen Forests


Many seniors of Lovers of Niiharu told me there is a book written by a retired city official who was actually in charge of the establishment of Niiharu Citizen Forest. But, as usual, not many people remembered the title. It took about 6 months for me to figure out which book it is. One weekend in May, I finally met it in one of the city libraries. Its title is “The Story of Making SatoyamaPark and Citizen Forest: Yokohama Maioka Park and Niiharu Citizen Forest,” written by Yoshikazu Asaba浅羽良和(あさばよしかず)「里山公園と『市民の森』づくりの物語」. (Tokyo: Haru-shoboh はる書房, September 2003, ISBN 4-89984-042-X) To know how the frontline of the City approached for Citizen Forest scheme, the book is very informative. Mr. Asaba started his working life as a landscaping architect for the city of Yokohama in 1963 and retired in March 31, 2000, 5 days after Niiharu joined the Citizen Forest Family. He stayed in one job for his entire life, to create and conserve greenery in the city of Yokohama. He wrote in 1963 the city office building was a neighbor of many vacant spaces that were occupied by American Occupation Army until recently. Since then, Japan went through rapid economic growth, Yokohama had a population explosion, and the acreage of city park grew from 197 ha in 1963 to 1576 ha in 2000 (; these numbers do not include Citizen Forests or the other conserved greenery). One of Mr. Asaba’s retirement parties was organized by the citizen volunteers who worked with him to establish Maioka Park. The volunteers celebrated his “graduation” by tossing him into the air, i.e. Do-age 胴上げ (; an example is here) … er, it’s difficult to explain … it is the most affectionate way in Japan to applaud somebody’s achievement by a group of people.


Satoyama rice paddies next to Maioka Park in May.
They have completed rice planting already.

When in 1853 Commodore Mathew Perry visited Japan to prize open the closed Japanese door for the Western world, the current downtown area of Yokohama was in the middleof reclamation process of swamps dotted along the coast. Closed Japanese economy constantly required more land for rice cultivation. Nearby Edo (Tokyo)had already 1 million population in 1721. People intended to plant rice along the Yokohama coast. On the other hand, samurais in 1853 did not want to have much contact with foreigners anyway and tried to contain gaijin’s movement without provoking cannons of Commodore Perry. Yokohama’s now-downtown area was a loch surrounded tiny but steep hills, many swamps which were under construction for filling, a sandbank, and rivers. The geography was ideal to lock-up strangers who wanted to stay near Tokyo. Moreover, the land reclamation was completed in 1856 that provided the places for foreigners to build western style buildings, including gardens and parks. The new town for Westerners was born with the first western style gardens /parks in Japan, which is the downtown of Yokohama. Yamate Park was the first Japanese public park built in 1870. Mr. Asaba suggests the history provided a background for the municipal office to think greenery in the city, i.e. a variation of Western approach for Regent’s Park, Central Park, Champs-Elysees, or Unter den Linden. Large well-manicured parks are “in,” like Yamashita Park or Minato-no-Mieruoka Park, and trees lining boulevards are must-haves, such as Ohdori Park and roads in Minato-Mirai area. All of those parks and boulevards are public and maintained by the City. The downtown area of Yokohama is almost entirely reclaimed lands, and the work is still going on. (Do you know there is a plan to reconfigure the mouth of Katabira River and Aratama River next to Yokohama Station?) To see the evolution of Yokohama’s “coast,” I recommend you to go to the south underground corridor connecting JR East ticket gates and Tokyu Toyoko gates in Yokohama Station. The walls there is a mini-museum explaining the construction process of the vicinity of Yokohama Station from the 19th century to the present. When I first saw the photos there, I was frankly flabbergasted … no wonder some call the area around Yokohama Station is Japanese version of Sagrada Familia, i.e. a perpetual large construction process. I guess 150 years of modern city planning this way was good for tourism business. When you ask any (non-Yokohama-local) Japanese about Yokohama, they would say “Ah, that port city with lots of western style park and fashionable streets, isn’t it?”

This is how tourists perceive greenery
in Yokohama.
Woooooooo, it’s very Yokohama (for visitors), isn’t it?

Underground mini-museum

When Mr. Asaba became a city architect, Yokohama was in the middle of population explosion. The provision for public spaces could not keep up with the change. As of 1982, we Yokohama people had the least park acreage per capita, 2 m2, among the largest cities in Japan. In the same year, the top was occupied by the people in Kobe who had more than 7 m2 (… well, it’s still not much). So, Mr. Asaba was busy building municipal playparks for kids in the newly developed residential areas. I remember when I was in elementary school, our playfields was swamps and rice paddies that were surrounded by small forests. Due to untreated household effluent, contaminated stinky river ran nearby, and the rice paddies hosted strong (and definitely not indigenous) American crayfishes. The forests housed rhinoceros beetles and stag beetles that made our summer recess gorgeous. Soon the rice paddies became condos and supermarkets. The swamps were reclaimed to be community parks with swings and picnic benches under the newly planted cherry trees. Decades later the coverage ratio of sewer in Yokohama became 99.99%, which brought back sweetfish to rivers. Next to the former stinking river is our now decades old local parks with pretty cherry blossoms and pansies surrounded by houses and condos. … Where are the beetles?

Meanwhile, according to Mr. Asaba, his next cubicle colleagues for agricultural policy division were probably in a crisis mode because of the loss of traditional scenery in the inland area of Yokohama. Beyond the hills surrounding the downtown for foreigners, an ancient highway, Tokaido aka Route 1, runs between Tokyo and Kyoto. Many routes are spreading from Tokaido, including the road of ironmongers in the Enkaisan area to Kamakura. There were many agricultural villages connected by the road network where the traditional Satoyama life thrived for more than millennia, but was brutally destroyed by housing developments with bursting population. (… er, well, our family moved from Tokyo when I was a kid). When in 1969 new City Planning National Act 新都市計画法 became effective, the officers in agriculture policy division of Yokohama took an initiative to establish unique criterion for zoning and managed to set aside at least 25% of the city for greenery as urbanization control area. In 1971, the City merged agriculture bureau and park division in order to establish Green Policy Bureau 緑政局 as a one-stop-shop for greenery policy, which was the first governmental experiment in Japan. In the same year, zoning and industrial policy for agriculture in the City was codified 「農業専用地区」制度・要綱 and Outlines of Special Measures to Preserve Greenery in Yokohama 緑地保存特別対策要綱 was established. They were followed by the City Ordinance for Create and Nurture Greenery 緑の環境をつくり育てる条例 in 1973. These 3 policies became the administrative foundation for Citizen Forests. In those early days, the city office which was in charge of Citizen Forests was the agriculture division, not the park division, though they were in the same Green Policy Bureau. So, from the beginning the Citizen Forest program was based on the agreement between the city and the landlords whose ancestors are farmers of Satoyama villages, and the spirit of the policy was for preserving Japanese agricultural tradition, which was very collective. Idea for involving community and partnership between the local government and civil societies were “inevitable,” Mr. Asaba wrote. The borderline case was the forests of Enkaisan around Kanazawa Zoo. In 1969, Kamariya, Mine, Hitorizawa, Segami, Kanazawa, and Nature Sanctuary Forests were designated as a special green space by the Act on the Conservation of Suburban Green Zones in the National Capital Region 首都圏近郊緑地保全法. The city of Yokohama allocated the job to take care of them to the park division, not the ag division. I had a kind of a-ha moment. That’s why Rokkokutoge Hiking Route is surrounded by houses, and very little professional agricultural land nearby. It would be due to “difference in policy priority” between the ag and the park divisions in the city office.

Mr. Asaba wrote for some time city officials were aware of such uncomfortableness in the green policy. So, the staff started a project to reorganize the Green Policy Bureau. (Oh yeah, it’s not some outside management consultants who did it.) In 1987, they completed the sorting of the Bureau’s job into ag policy, urban park issues, creation of greenery, and coordination of the above 3 within the Bureau. They decided to let the office in charge of greenery creation, greenery policy division, take care of all the Citizen Forests. At the same time, the city began to organize the system to connect forests that desperately needed maintenance jobs, and ordinary Yokohama people who wanted to be engaged in conservation of local greenery. The city officials defined their job as a coordinator between the forests and the volunteers, i.e. they decided not to monopolize forestry in the city. In 1994, the city began organizing formal support system for volunteers. The project included calls for volunteer participants, town hall meeting for local community to explain the idea of forest conservation by civic partnership, coordination between volunteers and ward offices, lectures of environmental science by college professors, lab sessions for thinning trees, how-to for democratic group formation (you know, planning for a fair organizational structure, deciding quorum system, making a rule of the group … that kind of things), and volunteer-wide networking conferences. The networking was culminated in 1998 when Yokohama hosted the 6th Congress for the Coppice of Japan. Mr. Asaba wrote he moved to Greenery Policy Division in 1996 and organized lots of those programs. He never experienced a shortage of citizen participants, and concluded people in Yokohama really wanted to have a direct and daily connection with green environment, not just pass through a tree-lined road. By then, Mr. Asaba has accumulated professional experience of partnership with civic organization in Maioka Forest. There is a story. I write it in the next post. J

In search for lost butterflies: Yokohama Citizen Forestry Guideline and Conservation / Management Plan 横浜市森づくりガイドラインと保全管理計画


The creation of the Niiharu Conservation and Management Plan 新治保全管理計画 was, it seems to me, a kind of a pilot project in Yokohama Green Up Plan. In Yokohama Citizen ForestryGuideline and Conservation / Management Plan 横浜市森づくりガイドラインと保全管理計画, they discuss the experience when Niiharu was creating the Conservation and Mangement Plan. Oiwake and Yasashi Citizen Forests are also the topic in the Guideline so that these north forests in Yokohama are the pioneers of forest management with strong volunteer participation in Yokohama. Measuring the success in terms of biodiversity, the pilot forests are very successful and no wonder the replication continues now with the other forests in Yokohama.


Could you figure out a female pheasant in the middle?
It’s a wild bird I found the other day
in a farm land in Niiharu.

The Guideline consists of 3 parts. First they introduce us the overall feature of greenery in Yokohama and the necessity of a tailor-made Conservation and Management Plan (CMP). Then, the Guideline explains the method to create a CMP, really in step-by-step. The third part is a very practical and comprehensive guide for actual forestry works based on ecology for each of the environments the forests in Yokohama contain, including the area immediately next to the housing development. The third section of the Guideline was the most popular among the budding forest volunteers who attended the introductory forestry course last fall. It leaded to excited discussions about obtaining the license for chainsaws. Anyway, before unleashing our inner desire to wield a chainsaw, we need CMP. “Don’t cut trees randomly!” Yeah.


The trees are coppiced in Maruyama of Niiharu
last February … though they are still too tall.

The Guideline tells us as of 2012, only 29.8% (12,972ha) of Yokohama is covered by green where 58% of it are forests. The 2000 research done by the Ministry of the Environment found only 0.2% of Yokohama’s greenery is the original biota of the area, i.e. 99.8% of 12,972ha is Satoyama with very long-term human interventions. For Yokohama, Satoyama provides more biodiversity so that the key to achieve rich environment in the city is slow and controlled human intervention. In the 21st century urban life, people do not have immediate incentive to recreate traditional Satoyama life. In order to attain environmentally friendly Yokohama, it is necessary for the urbanites to have a CMP with a clearly defined image for the future of a forest in 20 years ahead. The future vision is the first thing CMP shall have. For Niiharu’s case, it is the Niiharu Charter. Second, when we visualize scenery of Forest A in 2035 Yokohama, it will have a community of living creatures that is for a target vegetation in the CMP. To make the goal realistic, we have to think the current condition of the forest with respect to its geology, biology, and relationship with the urban human life. Inevitably we cannot ignore the history between the place and the humans in addition to the natural biota of the area. Adding possible resources the management can mobilize now, the objective becomes very specific for a small zone within Forest A. As one forest can have numerous zones, it will also have a variety of target vegetation. Finally, in order to achieve a target by the volunteers who are basically city dwellers without previous experience in forestry, people do need step-by-step instructions for the job in terms of timing, the method of intervention, resource allocation, and monitoring and evaluation. Moreover, if a forest has many zones with different targets, the work required for each aim will differ. It is the reason why we have a bulky volume for Niiharu Conservation and Management Plan with detailed work plans for dissected zones with specific target vegetation each.


Within a forest, Niiharu hides many large cherry trees.
People were picnicking under the flowering trees.

I guess it is probably something of “lessons learned” after rampant deforestation and impoverished urban environment in the decades of almost unchecked housing development … The Guideline emphasizes the importance of continuous monitoring and evaluation by the citizen forestry. All the tailored CMPs shall have indicator fauna and/or flora for target vegetation each that tell(s) volunteers our work has achieved an original objective, and we will maintain the environment as such in perpetuity. Here fauna includes urbanites who visit the forest for weekend relaxation. The forest volunteers are expected to watch continuously and carefully the soil, the winds, the sunshine, the composition of plant / animal community, and the usage by visitors in the forest. The information from monitoring will be evaluated among all the concerned parties promptly to be utilized for a timely modification in coordinated activities. I realized why the lecturers in the Introductory for Forest Volunteers in Yokohama emphasized the forte of volunteers … as detailed and continuous eyes of the protectors of forest. When we consider the glacial pace of eternally understaffed bureaucracy, and the vegetation could be in threat of bulldozers any time, it would be effective to station willing people who care continuous human cohabitation with the terroir. Otherwise … I am shocked to know beautiful sasakia charonda that was so familiar when I was in kindergarten is now near extinct in my home city. The caterpillars eat leaves of celtis sinensis and the adults drink sap from quercus acutissima and quercus serrata. All the trees are of Satoyama, and they were destroyed massively for houses and condos … The absolutely practical Guideline recommends not to make sasakia charonda as an indicator for volunteer activities, but choose hestina persimilis japonica instead. Sad. Very sad.


Table manner of a bird of prey

After listing the necessary contents in a CMP, the Guideline talks how to make a CMP. Though the process explained is in detail, the summary is simple: coordination. In order for a CMP to be useful for a forest, everybody who engages in conservation and management understands and consents with the contents. The Guideline says a CMP must be an agreement from the beginning among the people who care the forest. So, during the course of drafting a CMP, people must decide who does what, and an institutionalized way to harmonize the activities after the CMP becomes operational. It is a kind of natural for a council to be born. At the beginning the parties who have a stake for the forest meet regularly to draft the CMP. During the discussion the division of labor gets clearer. People could imagine possible contingencies in a practical sense, and arrange the way how to deal with probable “matters.” What if when the Lovers of the Forest realizes that a work is more dangerous than it is expected in the CMP? Let’s make such incidents to be in the possible agenda for the council meeting. Bounty Community Association may spot strangers who could be thieves for the area. Well, we establish lines of communication for the issue to be informed swiftly among the council members and the police. How about a new task that is not in the CMP but realized as necessary later? We predetermine how to deal with such cases before the CMP becomes operational. Hey, who’s gonna coordinate all of these? The Guideline recommends to choosing somebody who has a good communication skill with broader basic knowledge for the forest, rather than a geeky expert. (Wooo …) The Guideline shows us an interesting experience with the Niiharu’s CMP. I’ll tell you in my next post how my senior volunteers did it.

Oh, by the way, as of April 3, there remain only 3 logs of 20m long Japanese cypress and chamaecyparis pisifera in the Mukebara of the Niiharu Citizen Forest. We are still working as a human crane. My BMI is improving. Yayyyyyyy!
