“…The class "other land use types", which includes urban areas, showed a minor increase (around 1 %), suggesting that the decrease in NDVI was most likely caused by forest cover loss and not by urban expansion (Table S9). The same observations on LULC change in Indonesia were also done by Lee et al (2011), Margono et al (2012, 2014 and Luskin et al (2014). Luskin et al (2014) showed that in Jambi, during the period 2000-2010, forests decreased by 17 % while oil palm and rubber area increased by 85 and 19 %, respectively.…”

Given these trends in LULC changes, the observed LST trends were most likely caused by gradual decrease of forest cover loss at the expense of agriculture and croplands.…”

Expansion of oil palm and other cash crops causes an increase of the land surface temperature in the Jambi province in Indonesia

Abstract. Indonesia is currently one of the regions with the highest transformation rate of land surface worldwide related to the expansion of oil palm plantations and other cash crops replacing forests on large scales. Land cover changes, which modify land surface properties, have a direct effect on the land surface temperature (LST), a key driver for many ecological functions. Despite the large historic land transformation in Indonesia toward oil palm and other cash crops and governmental plans for future expansion, this is the first study so far to quantify the impacts of land transformation on the LST in Indonesia. We analyze LST from the thermal band of a Landsat image and produce a highresolution surface temperature map (30 m) for the lowlands of the Jambi province in Sumatra (Indonesia), a region which suffered large land transformation towards oil palm and other cash crops over the past decades. The comparison of LST, albedo, normalized differenced vegetation index (NDVI) and evapotranspiration (ET) between seven different land cover types (forest, urban areas, clear-cut land, young and mature oil palm plantations, acacia and rubber plantations) shows that forests have lower surface temperatures than the other land cover types, indicating a local warming effect after forest conversion. LST differences were up to 10.1 ± 2.6 • C (mean ± SD) between forest and clear-cut land. The differences in surface temperatures are explained by an evaporative cooling effect, which offsets the albedo warming effect.Our analysis of the LST trend of the past 16 years based on MODIS data shows that the average daytime surface temperature in the Jambi province increased by 1.05 • C, which followed the trend of observed land cover changes and exceeded the effects of climate warming. This study provides evidence that the expansion of oil palm plantations and other cash crops leads to changes in biophysical variables, warming the land surface and thus enhancing the increase of the air temperature because of climate change.

“…Modelling with site-specific variables, however, is not encouraged due to the by-catch nature of the data. A different sampling strategy and greater sampling efforts to include data on variables will be required to study the correlation between site-specific variables and occurrence.Bearded Pig and Wild Boar are known to forage in oil palm plantations that lie adjacent to forests (Hone 1995;Maddox et al 2007;Luskin et al 2013).

Camera trap data was used to study occurrence and daily activity patterns in the Endau Rompin Landscape of peninsular Malaysia during 2011, 2013 and 2015 to estimate Malayan Tiger Panthera tigris jacksoni population densities. By-catch data were also collected for seven ungulate species: Barking Deer Muntiacus muntjak, Bearded Pig Sus barbatus, Wild Boar Sus scrofa, Greater Mousedeer Tragulus napu, Lesser Mousedeer Tragulus kanchil, Malayan Tapir Tapirus indicus and Sambar Deer Rusa unicolor. Of these, Bayesian single-season occupancy analysis suggested that Barking Deer were the most widespread and Mousedeer spp. the least widespread during the study period. Bearded Pig, Malayan Tapir and Wild Boar were recorded in more than half of the camera trap area (Sambar Deer was excluded due to small sample size). Daily activity patterns based on independent captures in 2015 suggest that Barking Deer, Bearded Pig and Wild Boar are mostly diurnal, mousedeer species are crepuscular and Malayan Tapir strongly nocturnal.Keywords: Bayesian single-season occupancy, by-catch, camera trap, daily activity pattern, Endau Rompin Landscape, occurrence, peninsular Malaysia, ungulate.

Journal of Threatened 11246 INTRODUCTIONOf the 11 species of ungulates reported from Peninsular Malaysia (Francis 2008), 10 have been reported in the southern Endau Rompin Landscape (ERL). Banteng Bos javanicus, Gaur Bos gaurus and Sumatran Rhinoceros Dicerorhinus sumatrensis were recorded in the past century (Milton 1963; Davison & Kiew 1987; Burhanuddin et al. 1995 Table 1.These ungulates are likely the major prey base for the Critically Endangered Malayan Tiger in peninsular Malaysia (Kawanishi 2002; Goldthorpe & Neo 2011;Kawanishi et al. 2013;Rayan & Linkie 2015). Karanth & Sunquist (1995) found that larger carnivores selectively hunt larger prey when available. A decline in large ungulate prey has been reported to be linked to a decline in a tiger population (Ramakrishnan et al. 1999). Understanding the ecology of large ungulate prey is, therefore, important to predator conservation.Collecting information about these ungulates can be useful to tiger conservation in the ERL.Camera trapping is an effective non-invasive method to study shy and reclusive wild animals (see Ancrenaz et al. 2012;Sunarto et al. 2013; Trolliet et al. 2014). Detection/non-detection information captured by camera traps can be used to study species occurrence (O'Connell & Bailey 2011;Shannon et al. 2014) and activity pattern (Ridout & Linkie 2009). There are, however, some limitations on the use of these data as indicated by Liang (2015), including the fact that setting cameras at certain heights for large mammals sometimes misses smaller animals that pass by undetected.In 2011, 2013 and 2015, Wildlife Conservation Society (WCS) -Malaysia Program conducted intensive camera trapping to estimate Malayan Tiger population densities in the ...

“…Aspects related to human-animal interaction, like human-wildlife conflict and illegal hunting, have been addressed through the production of specific methodological frameworks by conservation organizations (365) or through safeguards that prohibit or regulate hunting within plantations (e.g., 366), but on-the-ground implementation is often poor (111,367,368). On the other hand, initiatives do not provide concrete mechanisms to address off-site impacts related to indirect land use changes, increase pressure due to new infrastructure (e.g.…”
