Loss of canopy cover can also expose the forest floor to higher temperatures and faster drying.<\/p>\n<p>The November-December disaster killed large numbers of trees across parts of Batang Toru. Meijaard warned that the resulting dead and drying vegetation could leave the damaged forest more vulnerable to wildfire.<\/p>\n<p>That concern is heightened by the onset of a strong El Ni\u00f1o, which is already supercharging fires in other parts of Indonesia.<\/p>\n<p>\u201cWith a severe El Ni\u00f1o predicted, we are very concerned about droughts and the risk of fires escaping into the landscape already degraded by landslides,\u201d Meijaard said.<\/p>\n<p>Aikman of Mighty Earth expressed similar concerns, saying the combination of landslide damage, continued habitat disturbance, and prolonged drought could place additional pressure on the already fragmented Batang Toru ecosystem.<\/p>\n<p>Indonesia\u2019s weather agency, the BMKG, announced on July 30 that the country had officially entered a strong El Ni\u00f1o phase. It said the phenomenon is expected to further suppress rainfall across much of Indonesia and warned of increasing drought and forest-fire risks during the coming months.<\/p>\n<p>Early indicators suggest the national fire season is already unusually active.<\/p>\n<p>Data from <a href=\"https:\/\/nusantara-atlas.org\/monthly-burn-scars-and-fire-season-progress-now-live-on-nusantara-atlas\/\" data-wpel-link=\"external\" target=\"_blank\" rel=\"external\">FireWatch<\/a>, a new satellite monitoring platform developed by the forest monitoring platform Nusantara Atlas, shows that there were more than 637,000 hotspots across Indonesia as of Sept. 17, far higher than during the same time in 2019, which was the worst fire year in the platform\u2019s record.<\/p>\n<p>For Aikman, the concern is not that Batang Toru will necessarily burn, but whether the ecosystem is still healthy enough to prevent burning during the dry season, and to sustain the Tapanuli orangutan habitat.<\/p>\n<p>\u201cWe\u2019re at red alert now,\u201d Aikman said.<\/p>\n<p><strong>Citations:<\/strong><\/p>\n<p>Meijaard, E., Wafiy, M., Ni\u2019Mattulah, S., Dennis, R., Hadisiswoyo, P., Sheil, D., . . .
