The living landscapes Program is dedicated to
develop wildlife-based strategies for the
conservation of large, wild ecosystems that are
integrated in wider landscape of human influence
9
5 criteria for selecting landscape species
10
MAIN HABITAT TYPES
  • Hill evergreen forest
  • Dry evergreen forest
  • Mixed deciduous and bamboo forest
  • Dry dipterocarp forest
  • Savanna
  • Riparian

Landscape species for HKK-TY
Cover all habitat types threats

MAJOR THREATS TO HKK-TY
  • Local poaching main targets are tiger prey such
    as gaurs, bantengs,
  • sambars, wild pigs, muntjacs.
  • Habitat conversion to agriculture caused by
    villages living inside
  • the area and along the bufferzone.
  • Disturbance due to presence of Non-timber forest
    product collectors
  • during the mushroom season thousand people
    searching for
  • mushrooms.
  • Local fishing Overfishing in some streams and
    by-catches can
  • threaten species such as otters.
  • Disturbance due to increase traffic on roads and
    tourist sites.
  • Competition and diseases to wild ungulates
    from domestic cattles.
  • Pollutions from mining sites near the area.
  • Large development project proposals such as
    highways,
  • hydro-power dams.

CONCEPTUAL MODEL
GOAL Conserve wildlife and their habitat in the
world heritage site
Conservation Objective Maintain wildlife
Direct Threat Habitat loss
Indirect Threat Ineffective law enforcement
Intervention Systematic patrol

How do we measure threats?
Sitthichai Jinamoy (WCS) Thailand
25
Analyze Threat Distribution
7 themes
Stream DEM Village Ranger Road Slope Salt lick
Weight score into 3 levels
Convert to grid standardize
GPS Points of Threat (Poaching) (Illegal
logging) (NTFP collection) (Camps) (Agar-wood) (Ot
hers)
7 Threat Risk Factors (TRF)
Assume radius 3 km. from threat occurrences
Threat density (D)
Ranging Risk Score into 3 levels

Correlation
From these 2 maps, if we can control threat
distribution especially in the red zone, gaur may
return to utilize this area increasingly.
NEED !!!!!! Long term monitoring system
