This research aims to investigate forest landscape pattern changes in the Sakaerat Biosphere Reserve
(SBR), and to classify and assess changes of multi-temporal forest landscape types, and analyze
patterns using landscape metrics from 1980-2010. Landscape classification and assessment of
6 landscape types showed the natural forest landscape was the major landscape type and occupied
an area of 46.23% to 44.40%. Landscape changes had occurred mostly in disturbed forest, decreasing
from 10.22% to 3.99%, while forest plantations and urban and built-up landscapes increased from
1.61% to 3.71% and 1.36% to 2.98%, respectively. More importantly, the number of patches, mean
proximity, and interspersion juxtaposition indices assisted in determining the forest landscape
pattern changes. The trends of change in the indices values of forest landscape types were
subsequently used in relation to gains and losses in the context of forest landscape ecology to set up
the priority levels of recommendations on a forest restoration and management plan. Therefore, this
evaluation showed the priority levels of all forest landscape types in each of the management
zones. As a result, recommendations in the core zones of natural forest, disturbed forest, and forest
plantation landscapes were strictly limited to minimum restoration and management, but not
limited to natural regeneration and succession; while in the buffer and transition zones, forest
rehabilitation and reforestation, including regular patrolling and forest fire control were
recommended. In conclusion the integration of remotely sensed data and landscape metrics can
beapplied to quantify landscape pattern characteristics that directly relate to forest landscape
ecology and to obtain important ecological landscape information for a forest resources restoration
and management plan.
