How can roads and cleared land make travel between forest patches dangerous for wildlife?

Roads and cleared land create habitat fragmentation, which divides large forest blocks into smaller, isolated patches. This process poses significant dangers to wildlife attempting to travel between these areas:

• Increased Predation: As the distance between habitat patches grows, animals are at a higher risk of encountering predators while traversing the exposed, non-forested terrain.1
• Vehicle Collisions: Roads built to facilitate logging and other land-clearing activities introduce the risk of animals being struck by vehicles.12
• Exposure to Inhospitable Conditions: Animals may be forced to spend too much time in environments that lack the necessary cover or resources, leaving them vulnerable to harsh conditions.1
• Isolation and Genetic Bottlenecks: When patches are separated by long distances, it becomes difficult for individuals to meet and reproduce. This isolation can lead to genetic bottlenecks and may make fragments too small to support large or territorial species.12
• Edge Effects: The creation of new boundaries between forest and cleared land increases the extent of ecotones. These zones can expose interior-dwelling species to increased threats, such as higher rates of nest parasitism.3
