Justification
Agathis lanceolata has a history of exploitation for its timber and has undergone a decline in its extent of occurrence (EOO), area of occupancy (AOO) and quality of habitat. Its EOO is estimated to be 5,378 km², based on herbarium specimens and field observations. Overexploitation has led to a significant decline in numbers of individuals, habitat degradation and habitat conversion, extent of occurrence and area of occupancy. The subpopulations are severely fragmented, as more than half the individuals are in small and isolated patches. The estimated total population is less than 10,000 mature trees. Each of the main subpopulations contains much less than 1,000 mature individuals. Taken together, these data indicate an assessment of Vulnerable.

Threats

Major Threats
The species has a history of overexploitation. Although plantations have been established, illegal logging is still a problem. Habitat fragmentation due to the effects of repeated fires and land clearance is another problem with most subpopulations restricted to fragments of primary forest, generally in sheltered valleys.
