Breeding bird indicator. These official statistics published by Scottish Natural Heritage SNH track the abundance of Scotlands terrestrial breeding birds using results. Since birds are well surveyed through volunteer-based and professional surveys and many are widespread and abundant they are often used as indicators of environmental change. In conjunction with other well-monitored groups such as butterflies and bats these indicators are used as a proxy for the overall state of biodiversity in the UK and to track progress.

To use common birds as indicators of the general state of nature using large-scale and long-term monitoring data on changes in breeding populations across Europe. The all-species index of abundance Figure 1a reveals a steady decline from around 1992 to 2004 with the index in 2004 estimated to be 30 lower than in 1986. Therefore results of this assessment should be viewed as an early warning of changes in the environment.

Species associated with farmland woodland and wetland habitats as well as for seabirds pages 3235 and. Background Bird populations are considered to be a good indicator of the broad state of wildlife and.
