  3. 3. 2019-10-04 3 Background: Forest in Japan Forest cover: 68.5% (FAO, 2015)  Second highest percentage cover next to Finland in the developed countries  Remained stable for more than 150 years However, composition and locality change in recent 60 years  Forest increase = Forestation by rural population decrease  Forest decrease = Deforestation by urban concentration Human-modified landscapes that respond to change in human involvement > Typical example in Japan: Agricultural forest Satoyama
  4. 4. 2019-10-04 4 Background: Agricultural forests as a modified landscape -Satoyama  Human-modified landscape based on traditional, sustainable use for natural resources.  Japanese government is putting its efforts in conserving Satoyama landscapes > Represents nature-culture linkage & biodiversity However, it is questioned whether conservation of present state Satoyama remnants can play a similar role after the change in human involvement. > We will show how change in involvement to a human-modified landscape can affect its conservation values by focusing on wildlife presence. Sato = village Yama = mountain/forest Forestation Deforestation In recent 60 years… OR
  5. 5. 2019-10-04 5 Objective & Method Objective:Clarify the relationship between human involvement and the historical change of land use & wildlife presence. Method: Analysis of historical records Land Use Pattern  Land use & land cover survey maps (1884, 2016)  Aerial photographs (1947-1948, 2008-2017) Wildlife Presence  Interview survey to local communities  Road-kill reports  Museum research archives  Camera trap survey Case Study: Tsukuba City 50 km north east ofTokyo

  12. 12. 2019-10-04 12 Discussion: Human involvement to forest in the study area  Current Satoyama remnants have undergone functional change, which resulted in structural and compositional change.  It is questionable whether the human-nature coexistence conservation value of Satoyama remains unchanged.
  13. 13. 2019-10-04 13 Conclusion  We found that many Satoyama remnants have undergone functional changes in its land use and have equally affected wildlife presence.  Largely changed forests may retain wildlife conservation value through provision of habitats in general, although its ecosystem may have changed to a large degree.  While we agree that human-modified forests are important for conservation, change in usage patterns result in varied environmental outcomes.  This study provides an example that traditional human-nature coexistence should not necessarily be the primary conservation value in secondary natural environments which are subject to change in human involvement.
