Range and habitat

The range of von der Decken's sifaka has been confused by inconsistent sightings of individuals beyond the species' expected distribution. Most recordings of the species are in agreement of its distribution west of the Mahavavy River and north of the Manambolo River. Anomalous sightings have been attributed to river crossing events as a result of seasonal changes in river directions and sizes.
