00:00Sekurang-kurangnya 58 ekor orang hutan Tapanuli yang dianggarkan sekitar 7% daripada populasinya mati akibat banjir dan tanah runtuh
00:09di Sumatera, Indonesia tahun lalu.
00:12Kajian oleh Borneo Futures World Weather Attribution dan Liverpool John Moores University mendapati kematian berlaku di hutan Batang Toru, Sumatera
00:21Utara yang menjadi habitat utama spesies berkenaan dengan populasi sekitar 800 ekor.
00:30It's a critically endangered great ape. It only occurs in the Batang Toru region at the moment, but it used
00:37to occur like 100 or 150 years ago in a much larger area.
00:42So the area where we look at is really our last refuge, if you like. And the reason that it's
00:49only there is because of historical deforestation, historical killing and hunting by people,
00:57combined with a very slow life history. For anything to reproduce at a rate of maybe an offspring every seven
01:05years or so.
01:07So they're very vulnerable for any changes.
01:12Ujarnya jumlah sebenar mungkin lebih tinggi kerana kajian hanya meliputi sebahagian kawasan hutan tersebut.
01:18Extreme rainfall leading to saturation in soils, at least to a large extent in primary forests, where entire hill slopes
01:28just came down and in very, very rapid landslides.
01:34And it kind of, it fitted the picture of what we saw in Indonesian newspapers, on television, of vast amounts
01:42of timber being swept down these rivers.
01:45And then if you started picturing, well, if you get caught as an orangutan or any wildlife, and it's a
01:52very steep, dissected area.
01:55So if anything comes down, it comes down at great speed. Survival chances are going to be very minimal.
02:01So that's all.
02:02So we got hit, I thought about it.
