4.1. Landscape structure and configuration
Table 2 shows the comparison between the two mon-
tane evergreen landscapes selected for more detailed
study in the two sanctuaries. The two landscapes are
approximately the same size (20,481ha OK, 18,530 MT)
and do not differ appreciably in the total amount of
evergreen forest remaining in 1996 with 3403 ha, in OK,
and 2475 in MT. However, they do differ in two
important respects. The first is the change over time.
Between 1954 and 1996, OK lost 5% of its montane
evergreen and MT 50%. Secondly, not only did MT
lose about 10 times as much forest, the remaining forest
is also much more highly fragmented than OK. One
critical indicator of the difference in fragmentation
between the sanctuaries is the largest patch index (LPI)
representing the percentage of the landscape occupied
by the largest patch. In OK this comprises almost 17%
of the landscape, but in MT only 4%. In 1954 the cor-
responding figure for MT was 23%. There are a larger
number of smaller patches of more uniform size in MT
than in OK. The total core area is also significantly
lower in MT, with only 35% of its extent in 1954,
whereas OK retained some 86% of total core area
since 1954.
