History timeline

  • The PBMS was started 50 years ago by the Nature Conservancy.
  • In the 1960s there were serious concerns over the effects of organochlorine insecticides and organomercury fungicides on birds and mammals.
  • PBMS monitoring and experimental and ecological studies demonstrated adverse effects of organochlorine insecticides (particularly dieldrin and DDT) on predatory bird populations in Britain.
  • Our work contributed to the scientific evidence that led to bans on agricultural use of these insecticides in Britain and elsewhere.
  • The PBMS has measured levels of these compounds in predatory and fish-eating birds ever since.
  • The PBMS is the longest running scheme of its kind anywhere in the world.
