Some countries produce their own bird indicators. Are these indicators similar to the PECBMS indicators?
AnswerNot necessarily. Apart from indicators produced under coordination of PECBMS, countries produce their own wild bird indicators according to specific national needs (e.g. national legislation). Links to some national indicators also can be found on the PECBMS web site. They may deviate slightly from PECBMS indicators because of different methods of species selection and classification, computation procedure etc., that are tailored to the specific national purpose.
Learn more about national monitoring schemes in Europe in the country reports or about types of indicators that PECBMS produce in Methods, in chapter 3. Multispecies indicators.
