Sustainable forest management requires understanding landscape dynamics. This study reveals significant forest cover loss and fragmentation in Turkey
Area of Science:
- Forestry
- Ecology
- Landscape Science
Background:
- Understanding historical disturbances is crucial for sustainable forest ecosystem management.
- Landscape dynamics analysis provides insights into forest cover changes over time.
Purpose of the Study:
- To analyze spatial and temporal changes in land use and forest cover patterns in a mountain forest area in Rize, Turkey.
- To evaluate changes in forest conditions and landscape structure between 1984 and 2007.
Main Methods:
- Geographic Information Systems (GIS) and FRAGSTATS software were used for spatial analysis.
- Forest cover type maps from 1984 and 2007 were evaluated for temporal changes.
- Quantitative metrics were employed to assess landscape structure and fragmentation.
Main Results:
- A net decrease of 2.30% in total forested areas was observed between 1984 and 2007.
- Productive forest areas decreased by 12,506 ha, while degraded forest areas increased by 14,805 ha.
- Landscape fragmentation increased, indicated by more numerous and smaller forest patches due to timber extraction and illegal cutting.
Conclusions:
- Despite an increase in medium crown closure and regeneration, overall forest quality is challenged by decreasing total forest area.
- Rural out-migration contributed to land use changes and forest degradation.
- Effective forest management strategies are needed to address fragmentation and degradation in mountain forest ecosystems.
