Leonie and Teresa’s Friendship in the Kehje Sewen Forest

Recently, three members from our PRM team in Nles Mamse Camp – Jani, Usup, and Rizal – located Leonie and Teresa around Transect 7. These two female orangutans were released in September and December 2015 respectively and it was great to have the chance to record behavioural data on them in the Kehje Sewen Forest: Both have covered an extensive range since their release, and have been difficult to track.

New Hope for Land Destroyed by Failed Rice Project

Fire, encroachment, and the clearing of land for agricultural use are the biggest threats to Borneo’s forests and the wildlife that inhabits them. The irreversible damage to the land from the failed Mega Rice Project of the mid ’90s in Central Kalimantan is evidence of the long-term effects of forest clearing on the environment, the local community and wildlife.

Nest-to-nest observations involve documenting the daily activities of one orangutan for a whole day, from dawn until dusk.

Orangutan Friendships: The Power of Numbers

The orangutans from our last release group (Nyaru Menteng 12th Orangutan Release) have settled in at Batikap, and are beginning to go their separate ways. The excitement of freedom has worn off, and most of the orangutans seem to be branching off alone rather than spending time together. But, not all.

Orangutan Food Aplenty in the Kehje Sewen Forest

The biggest challenge in releasing orangutans back to the wild is finding suitable forest habitats for them to live in. In order to determine the viability of a forest as a potential release area, we first need to conduct a thorough phenology survey to ensure the area has a sufficient amount of natural food available all year round.

Dewi and Her New Baby

We quickly picked up transmitter signals for Mardianto and Compost – two of our more recently released orangutans, who had been observed spending time together over the past few weeks.

HOPE (Help Orangutans, Protect Earth)

The recent reclassification of the bornean orangutan from ‘endangered’ to ‘critically endangered’ by the IUCN indicates that the hard work we have been doing is still not enough. Wild orangutans are constantly being pushed out of their natural habitats.

Growing Up in Batikap

When I arrived at Totat Jalu Camp in March, I immediately saw Lesta and Lewis, a mother-and-son pair released to the Batikap Conservation Forest in February 2013. The pair could be seen in and around the camp, and they appeared to be very healthy and active. That day, I joined the PRM team to observe Lesta and Lewis and it was a priceless experience.

Orangutan Rescue Operations

The widespread fires across Kalimantan and Sumatra are devastating forests and peatlands and have resulted in not only human casualties, but also wildlife. As the fires continue to spread, wildlife is displaced from natural habitat and many species, including orangutans and sun bears, are forced out of their natural range and into closer proximity to human settlements or villages.
