s in Japan have been built in regions also used for satoyama. Satoyama have been disappearing due to the drastic shift in natural resources from charcoal and firewood to oil and the change from compost to chemical fertilizer. Also, the problem of aging in Japanese society can cause the disappearance of satoyama because there are fewer people who can work in satoyama which are considered as
intermediate disturbance on forests such as coppicing and harvesting trees for
timber and
charcoal, cutting shrubs for
firewood and collecting
litter as
compost. These human impacts can help the success of the forest occur. As the final causality of the disappearing of satoyama, pine dominated secondary forests in satoyama were increasingly destroyed since
pine wilt disease devastated pine forests in the 1970s. The disappearance of satoyama has led to threats in many wildlife that inhabit these areas. For example, the species
Niphanda fusca, a butterfly that can be found in satoyama landscapes, has become endangered partly due to the degradation of this ecosystem. This butterfly inhabits early stages of
succession; without human intervention, some satoyama areas have undergone progression into the later stages of succession, causing a loss of habitat for the butterflies.
N. fusca is listed in the Japan Red List as endangered – there has been around a 39% decrease in their records in prefectures. == Conservation ==
