Researchers studying Singapore's forests have documented thousands of insects and assessed the loss of mature trees in the city-state's reserves [1].
These findings are critical for understanding biodiversity loss and shaping future conservation strategies to protect the remaining natural habitats in Singapore. The data provides a baseline for how the ecosystem responds to the disappearance of large, old-growth trees.
The results were announced this week at the Festival of Biodiversity 2026 [3]. The research team, which included scientists from the National Parks Board (NParks), focused on the relationship between mature forest structures and the variety of life they support [1], [2].
According to the findings, the study documented thousands of individual insects across various forest sites [1]. This research contributes to a broader understanding of the region's ecology, with estimates suggesting there are over 100,000 insect species in Singapore [2].
The study specifically examined the loss of large trees in older forests. Mature trees often serve as keystone structures that provide nesting sites, food, and shelter for a wide array of organisms. The decline of these trees can lead to a cascading effect on the insect populations that depend on them [1], [2].
By recording these losses and documenting the current insect populations, the researchers aim to provide the necessary evidence to inform urban planning and environmental protection efforts. The goal is to ensure that future conservation work is based on current biological data, rather than historical assumptions [1], [2].
“The study documented thousands of individual insects across various forest sites.”
The documentation of over 100,000 estimated insect species alongside the loss of mature trees underscores a precarious ecological balance in Singapore. Because mature forests provide specialized niches that young forests cannot replicate, the loss of large trees may lead to a permanent decline in biodiversity. This data likely signals a shift toward more aggressive preservation of old-growth stands to prevent the collapse of local insect populations.
