On April 24th
Activity at Hiroshima Prefectural Central Park

Takuya Shimada

★My impression
greengreengreengreengreenIn this lecture, Professor Nakagoshi talked about the importance of biodiversity conservation in the Chugoku region based on several concrete research results, therefore I think all the participants including citizens were able to understand the content easily. Such an open-type lecture must be very important for creating a more ecological society in the near future, because people will be more and more interested in the biodiversity conservation.


greengreengreengreengreenI went to Hiroshima Prefecture Central Forest Park to participate in the open Lecture on Forest event. Professor Nakagoshi lecture titled "Biodiversity maintenance activity". The attendees in total 40 participated consisted of 17landscape ecology students and 23 members of public.
greengreengreengreengreenThe lecture’s subject was on national biodiversity strategy. From the Rio de Janeiro Earth Convention was adopted in 1992, then national biodiversity strategy was formulated, and proposals for how to overcoming the biodiversity crisis. The first is the proposal to protect biodiversity from development, and second is conservation of abandoned Satoyama, the third is to establish a good ecosystem with exotic species. Landscape preservation will lead to biodiversity conservation in the Chugoku region. The Satoyama initiative was adopted in COP10 (Conference of the Parties) held in Nagoya in 2010. The Satoyama concept promotes 2 important aspects “Symbiosis in nature" and "Sustainable use of natural resource".
greengreengreengreengreenNext, Professor Nakagoshi lectured about terrestrial ecosystems and biodiversity in the Chugoku region. Hiroshima Prefecture still has rare species in a few primary forests and secondary forests. However, many species become extinct due to abandonment of Satoyama in recent years. Therefore the establishment of a management is necessary for aforestation.
greengreengreengreengreenNext the attempt of biodiversity in Satoyama was mentioned conservation. In Japan the international environmental policy consists of “a recycling society established, global warming prevention construction of low carbon society" and "Conservation of biodiversity and sustainable use". However Satoyama is largely abandoned due to the lack of economic benefits. Regarding to the management of Satoyama, I would like to introduce what Professor Nakagoshi is doing in Higashi Hiroshima city. First, he examines how much wood biomass in Mt. Namitaki is possible to use it as fuel. Second, he used wood biomass from Satoyama management in Mt. Ryuou Higashi Hiroshima Ikoino Mori Park to purify river water, to produce charcoal and organic fertilizer for Sake rice. Both of these efforts relate to the creation of a circulating society and the establishment of a low carbon society.
greengreengreengreengreenThe last content is biodiversity conservation activity to conserve terrestrial ecosystems and biodiversity in the Chugoku region, we have to protect high quality natural ecosystem and promote the sustainable use of Satoyama natural resource and utilize new natural resources to coexist to nature.
greengreengreengreengreenCOP10 has introduced some NPO (Not-for-Profit Organization)/NGO (Non-Governmental Organizations)’s activities of Chugoku region. In the future, forest volunteers and CSR activities of private companies will be important in the conservation of biodiversity.
greengreengreengreengreenIn the afternoon, we observed Iris rossii in Hiroshima Prefecture Central Forest Park. The grand of Iris rossii habitat is limited, so it is designated as a natural monument in Japan. 200 Iris rossii clones were planted in this park and bloom from the end of April or the beginning of May. Iris rossii is investigated by lab students every May and we have found the number is decreasing year by year.

Iris rossii blooming at the Central Park

greengreengreengreengreenThere are five plots of Iris rossii, and we were split into 3 groups on that day. Professor Nakagoshi observed with the public. I, Mr. Masuda and Mr. Horii observed with landscape ecology students. We could find only 1 plot of Iris rossii blooming due to this spring low temperature of this year. That plot locates in an open area, which received enough sunlight therefore Iris rossii could bloom earlier.
