Monitoring

Present schemes
  • Point count routes, free choice, in summer since 1975 (267 routes counted 2009).

  • Point count routes, free choice, in winter since 1975/76 (309 routes counted in 2008/09).

  • Line transects ('Fixed routes') in summer since 1996. There are 716 routes distributed systematically, giving a semi-random distribution (519 of the routes counted in 2009).

Previous schemes
  • Census plots in summer 1969-1999.

Atlas work


Latest atlas
Census period: 1974-1984. Method: Breeding criteria 1-20 in 5 x 5 km squares.
No densities estimated. Atlas published in 1999 (Svensson et al. 1999).

Previous atlases
None.

Ongoing atlases
From 2003 onwards, some regions in southern Sweden repeat the work with the same methodology as in 1974-1984, but there is no national coordination.
