The effects of logging and fragmentation on bird diversity
MetadataShow full item record
Deforestation and forest degradation is occurring globally at an alarming rate. The annual net loss of forest cover has been reduced in the past decade through sustainable forest management and conservation measures. Despite this, the remaining forest is becoming increasingly degraded with the total area of primary forest declining. Avian diversity has been shown to decline in degraded and fragmented forests due to logging activities. In this review the impacts of logging on avian communities are assessed by comparing diversity between primary forest and degraded secondary forest, industrial plantations and forest fragment sizes. The major organisations and current initiatives that are involved with reducing the impacts of logging are discussed, which may help to mitigate the threats to avian diversity. The detrimental effects of logging activities are starting to be reduced globally which may limit the decline in avian diversity. Nonetheless many sensitive species reliant on undisturbed forest are still under threat. This highlights the importance of protecting the remaining primary forests from logging activities.
