Question 1

True or false: The Borneo rainforest has over 3,000 species of trees, more than in all of North America combined.

Accepted Answer

True. Borneo hosts around 3,000 tree species, making it a global biodiversity hotspot. By comparison, North America (from Canada to Panama) has roughly 1,200 native tree species, so the statement is accurate.

Question 2

True or false: Some Bornean trees have evolved to grow ‘buttress roots’ that can extend 30 feet from the trunk to stabilize in shallow soil.

Accepted Answer

True. Buttress roots are common in Borneo’s rainforests, helping tall trees stay upright in nutrient-poor, shallow soil by spreading widely.

Question 3

True or false: Borneo’s rainforest is home to the world’s largest flower, Rafflesia arnoldii, which can weigh up to 15 pounds.

Accepted Answer

True. Rafflesia arnoldii, found in Borneo, is the heaviest flower globally, reaching 15 pounds and emitting a rotting flesh smell to attract pollinators.

Question 4

True or false: Borneo’s rainforests produce more oxygen than the Amazon rainforest due to higher tree density.

Accepted Answer

False. The Amazon produces far more oxygen overall because of its massive size. Borneo’s rainforests are significant but not oxygen output leaders.

Question 5

True or false: Borneo’s rainforests have no native freshwater dolphins, only saltwater ones.

Accepted Answer

False. The Irrawaddy dolphin lives in Borneo’s coastal and freshwater rivers, including the Mahakam, making this statement incorrect.

Question 6

True or false: Borneo’s peat swamps are so acidic they can dissolve fallen animal bones within weeks.

Accepted Answer

False. Peat swamps are acidic (pH ~3–4) but not strong enough to dissolve bones quickly. Decay occurs slowly due to low oxygen, not acidity.

Question 7

True or false: Borneo’s rainforests are home to flying snakes that can glide over 100 meters between trees.

Accepted Answer

True. Flying snakes (Chrysopelea) in Southeast Asia, including Borneo, can flatten their bodies to glide. They can cover distances up to 100 meters (330 feet) between trees.

Question 8

True or false: Bornean orangutan offspring often remain with their mothers for up to eight years, a remarkably long childhood dependency for a primate.

Accepted Answer

True. Bornean orangutans have an extended learning period; juveniles stay with their mothers for up to 8 years to learn crucial survival skills.

Question 9

True or false: The Bornean clouded leopard is actually a separate species from the mainland clouded leopard.

Accepted Answer

True. Genetic studies in 2006 confirmed Bornean clouded leopards are a distinct species (Neofelis diardi), not a subspecies of the mainland clouded leopard.
