Canarium strictum is a large, 35 m tall, evergreen, canopy tree of the tropical rainforest biome in India, China, Myanmar, Thailand and Bhutan. This tree grows at elevations of 300-1,600 m. The species has an extent of occurrence (EOO) of 3,168,613 km², but this could be an underestimate as it is based on an incomplete map. There are many subpopulations. It has a density of 2.7 -13.8 per ha estimated for the species. The species has ecological importance for its characteristic niche in the canopy tree associations and has relationships with hornbills and ungulates for dispersal. There is a continuing decline in the number of mature individuals due to commercial extraction of its resin leading to die back of mature trees. The species is further threatened by habitat loss due to agro industry plantations, logging, and dams and reservoirs. Due to ongoing habitat loss and resin extraction the total reduction in population is suspected to be at least 50% reduction over the last three generations. Few conservation and monitoring programmes are in place. Hence, the species is assessed as Endangered (EN). 

The species is distributed in India, China (Yunnan) and Myanmar. GBIF also records points of the species in Bhutan and Thailand, which are also included in the distribution of this species for this assessment.

The population estimated for the species is at least 35,360 mature individuals with an abundance of 2.7 -13.8 per ha. The species is one among the most impacted by resin extraction for commercial purposes. Seventy percent of the mature individuals are tapped for resins and continuous and immature tapping has led to the death of 27% percent mature trees (Amitha Bachan and Anitha 2013). Due to ongoing habitat loss and resin extraction the total reduction in population is suspected to be at least 50% over the last three generations (210 years).

Canarium strictum is a large and dominant canopy tree of the tropical rainforest biome. This species is seen in the primary tropical rainforests within an elevation of 300-1,600 m. It is associated with other tropical rainforest canopy trees such as Palaquium ellipticum, Mesua ferrea, Vateria indica etc. The species is seen in good quality primary rainforests but extracted traditionally for its resin. The abundance is 2.7 -13.8 per ha in its available locations and the sapling density is 0.03 per ha. The seeds are dispersed by hornbills and smaller mammals (Amitha Bachan and Anitha 2013).

Apart from the habitat loss due to agro industry plantations, logging, and dams and reservoirs, the major threat is tapping this tree for resin. Seventy percent of the mature individuals are tapped for resins and continuous and immature tapping has led to the death of 27% percent mature trees (Amitha Bachan and Anitha 2013).

Canarium strictum is one of the most exploited evergreen tree species for its resin. The resins are traditionally tapped for commercial value. The resin is extracted traditionally by indigenous communities for fumigation, and has commercial value as Minor Forest Produce. It is also used in traditional medicines.

The tree is impacted by traditional tapping of its resins. There are some awareness and community-based monitoring programmes in place (Amitha Bachan and Anitha 2013). The species has been nationally assessed as threatened in India and possibly threatened in China (BGCI 2023).
