Corridors can exacerbate fragmentation
|
Detailed explanation-1: -Another concern about corridors is that they may increase predation rates. If prey are dispersing through corridors, this may provide the perfect bottleneck of which a predator can take advantage. This, also, is a valid concern that is not strongly supported by scientific evidence.
Detailed explanation-2: -Corridors are not always beneficial to maintaining biodiversity because they can aid the spread of pests, disease and fire. They can also sometimes be too narrow to provide valuable habitat.
Detailed explanation-3: -Corridors help increase survival for many species by; increasing food sources, providing valuable cover, decreasing the chance of predation, and by reconnecting fragmented and isolated populations.
Detailed explanation-4: -Negative edge effects include increased risk of parasitism or disease, increased risk of predation, adverse microclimate conditions, and competition from invasive species. These factors should be considered when designing corridors.
