Cyclops Landscape Research Programme

A living laboratory from reef to ridge to lake

The Cyclops landscape spans the Cyclops Mountains, Lake Sentani, Tanahmerah Bay and Youtefa Bay, creating an extraordinary transition from coral reefs and mangroves to lowland and montane rainforest within a compact geographic area. The landscape supports globally significant biodiversity, Indigenous communities, protected areas and some of YAPPENDA’s most active long-term research and conservation programmes.

A Landscape Built for Long-Term Research

Camera-Trap Network
Existing survey transects extend from near sea level to almost 2,000 m across different habitats and disturbance levels.

Long-Term Monitoring
Multiple permanent forest plots and expanding monitoring stations provide a foundation for longitudinal ecological research.

Restoration Sites
YAPPENDA maintains rainforest and mangrove restoration sites that can support research into restoration ecology and ecosystem recovery.

Research Infrastructure
Accommodation, vehicles, field equipment, reliable internet, workspace and logistical support are available through YAPPENDA’s Sentani facilities.

Collecting Data in the Forest

In this video, Jeff Wonda explains how YAPPENDA’s field team retrieves and records camera-trap data to monitor wildlife and strengthen biodiversity research in the forests of Papua.

Three women are engaging in a water activity near a waterfront with tropical trees and houses in the background. Two women are in the water holding a stick, and one woman, standing on a platform, is holding a stick or pole, possibly involved in a traditional activity or fishing. The women are dressed in casual clothing and head wraps, with one wearing a striped top.
