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

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.

Yama = mountain/forest

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

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.

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.
