Figure 5.1 - UK populations of wild birds
Figure 5.1 shows indices of the populations of woodland birds in the UK since 1970, for generalists, specialists and total. The base year is the year 2000 where the index value is 100. It shows that the index for specialist birds fell from almost 150 in the early 1970s to less than 110 in the early 1990s, with only a limited further decline since then. The index for generalists has fluctuated above and below 100 since 1970.
