A wetland margin in a highland valley
Kuk lies around 1,600 meters above sea level in New Guinea’s Wahgi Valley, among slopes, forests and wetlands. Residents used plants and altered land through clearance, fire and digging. Around 5000–4400 BCE, mounded cultivation developed along wetland margins, elevating planting surfaces above wetter ground. Soil, rain and vegetation shaped both available food and the maintenance required. Repeated work gradually established cultivated areas within a landscape that continued supplying materials and other resources.

Mounds and the propagation of food plants
Mounds allowed cultivators to adjust soil and moisture around plants with differing needs. Microscopic remains record food resources including taro and bananas. Propagation depended on moving plants or retaining material for subsequent planting. Preparing ground and selecting edible plants connected harvests with the next cycle. These tasks accumulated practical experience over time. Cleared ground required continuing maintenance, and seasonal work helped keep cultivated spaces productive within the valley’s varied environments.

Land management recorded in the ground
Cultivation reduced some forest cover and expanded disturbed vegetation, changes preserved in wetland sediments. Later ditch systems created different field arrangements and required clearing and alteration. Mounds, channels, pollen and plant residues allow comparison among these successive forms of production. Kuk records highland communities combining plant propagation, soil preparation and water management. Their continuing adjustments turned repeated household and communal labor into a long history of food production on land shaped by generations of use.
