Kalimantan within Borneo
Pongo pygmaeus lives on Borneo, an island extending beyond Indonesian Kalimantan. BOS Foundation describes three subspecies with different distributions. Orangutan maps should distinguish biological and geographical boundaries; a place name or resemblance in a photograph alone cannot reliably establish a subspecies.
Peat swamps are important forests
Peat-swamp forests provide important Bornean orangutan habitat alongside other lowland forests. Drainage and fire can change those conditions. Protecting trees and maintaining the water system are connected tasks; replanting alone does not establish that a swamp’s ecological functions have recovered.
Learning to read behaviour
Orangutans make resting nests and communicate through varied sounds and movements. BOS explains that some calls can indicate discomfort. People should not interpret proximity or apparently calm movement as an invitation to interact. Good observation leaves the animal the choice to move away.
Rehabilitation and habitat protection
Caring for rescued orangutans and protecting wild orangutans address different needs. Rehabilitation does not make every individual suitable for release. Distinguish animals in care, animals released, and monitored wild populations in reports; these figures cannot simply be added together without context.
Helping through everyday choices
Support work explaining forest protection and trade prevention through verifiable outcomes. Avoid paid photographs involving contact with orangutans. Continue to the Sumatran and Tapanuli profiles to understand species differences; all need attention without combining their distribution or population data.
