Despite population growth, mountain gorillas face inbreeding challenges due to their small gene pool, leading to minor genetic defects like webbed digits and crossed eyes. While the population has increased from 250 to 600 in the Virunga area, the risk of devastating disease outbreaks remains a significant conservation concern.
Impact: High. This underscores the delicate balance of conservation, where population recovery must be managed alongside genetic health to ensure long-term species survival.
