Map of the KAL estate in West Kalimantan, Indonesia using the Tropical Moist Forest (TMF) baseline dataset produced by the European Commission’s Joint Research Centre (EC JRC) [7].
TMF data were generated under studies funded by the Directorate-General for Climate Action through the Roadless-For pilot project and the ForMonPol project. Data are provided free of charge under the Copernicus Regulation. Proper attribution follows JRC requirements (forobs.jrc.ec.europa.eu/TMF/data). TMF dataset described in Vancutsem et al. [7].

Fig 4.
Comparison of key statistics between different models.
(A) Mean detection (± se; backtransformed intercept; see text) and (B) mean occupancy (± SE) in 2020–2024 of 23 species. Each bar represents a different dataset. Asterisk indicates significant difference with standard dataset (paired t-test; P < 0.05; n = 23).
