What modification applies to the natural-conditions rule concerning trees in urban areas?

The correct answer highlights that landowners in urban areas have a responsibility to inspect the trees on their property. This aligns with the natural-conditions rule, which generally holds landowners liable for damages caused by natural conditions on their land, including trees. In urban settings, where trees are often in close proximity to human activity and infrastructure, it becomes crucial for landowners to regularly inspect their trees for any potential hazards, such as dead branches or signs of disease.

By ensuring that trees are well maintained and monitored, landowners can minimize the risk of damage to people or property that may result from neglect. This duty to inspect adds an urban-specific modification to the natural-conditions rule, differentiating it from rural areas where landowners may have less interaction with the natural conditions surrounding their properties.
