MEGA DIVERSITY COUNTRY

Indonesia : - 11 percent of the world's flowering plants (352 000 spc), - 12 percent of the world's mammals (5 500 spc) - 15 percent of all amphibians and reptiles (25 000 spc) - 17 percent of all birds (10 000 spc) - 37 percent of the world's fish (32 000 spc)

Impact on Species a) Extinction forest specialist

species b) Extinction of core/interior

species c) Species isolation -> lead to

extinction d) Increase edge species e) Increase habitat generalist

Concept of Edge Species & Interior species

Edge

Core/Interior

Edge : under two different micro-climates (bare land & forest) Core/Interior : core/interior part of remnant forest

Case 4 : Second Habitat Sumatran Tiger Conservation ZSL-Indonesia, PHKA & LIPI

Sumatran Tiger was captured GPS collar was set up After several months was released in To new habitat (second habitat)

Sumatran Tiger were spending more time in secondary forest & forest edge (border between forest non forest, disturb forest)

Lead to conflict with community

Lead to extinction due to poaching/hunting

Release Point

Every one hour the GPS information was received

Case 6 : Habitat Suitability : Macrocephalon maleo SAL. MULLER, 1846

Bogani Nani Wartabone

a. Endemic to Sulawesi and Buton Islands

b. Endangered (habitat destruction, fragmentation, small population, rapidly decline)

c. lay their eggs in the ground/sand and let the warm soil do the incubation

Summary Habitat Loss & Fragmentation have been occurring,

Lead to species extinction

Remote Sensing & GIS is powerful tools : understanding distribution of species, changes process, structure & function of the landscape

Need further exploration

Thank you very much !
