Summary of survey effort and detection of tigers in five landcover types in Riau Province, central Sumatra.
<p>*number of sites where the species was detected divided by total number of sites surveyed.</p
Top models (<i>w</i><sub>i</sub>>0) for tiger probability of habitat use (ψ<sub>1-km</sub>) in central Sumatra across all landcover types in the landscape based on detection history data collected at transect sites (n = 1857, 1-km transects) in six landcover types.
<p>Note: Psi = probability of site occupancy/habitat use; p = probability of detection; thta0 = spatial dependence parameter - probability that the species is present locally, given the species was not present in the previous site; thta1 = spatial dependence parameter -probability that a species is present locally, given it was present at the previous site. LCCode = landcover code; AltDEM = Altitude; Precip = Precipitation; dtwater = distance to freshwater; Dtfedge07 = distance to forest edge; dtf05cr = Distance to nearest centroid of forest block greater than 50,000 ha; dtpacr = distance to centroid of protected area; Dtmprd = Distance to major public road; LCFor = forest(1) or nonforest(0).</p
Top models (<i>w</i><sub>i</sub>>0) for probability of habitat use (ψ<sub>1-km</sub>) by tigers based on detection history data collected at transect sites within acacia plantations (n = 268, at 1-km transect scale) in central Sumatra.
<p>Notes: Psi = probability of site occupancy/habitat use; p = probability of detection; thta0 = spatial dependence parameter representing the probability that the species is present locally, given the species was not present in the previous site; thta1 = spatial dependence parameter representing the probability that a species is present locally, given it was present at the previous site. Dtwater = distance to freshwater; Dtmprd = distance to major public road; dtfedge07 = distance to forest edge; dtpacr = distance to centroid of protected areas; dtf05cr = Distance to nearest centroid of forest block greater than 50,000 ha; Precip = precipitation.</p

Estimated probability of habitat use (ψ<sub>1-km</sub>) by tigers in six land cover types.
<p>These estimates were produced from the best model for each landcover (bars) and ratio of plantation's probability of use (diamonds) relative to forest based on a) landscape covariates and b) manual covariates.</p
