Emeritus Professor Harry Frederick Recher RZS (NSW) AM (born 27 March 1938, New York City) is an Australian ecologist, ornithologist and advocate for conservation.

[2] From 1968 he worked for 20 years at the Australian Museum as a Principal Research Scientist, focussing on conservation issues and the biology of forest and woodland birds.

In the 1980s, Recher and his colleagues applied these studies to identify the conservation requirements for native birds and animals in their specific habitats.

In 2003 the statutory management plan, NPWS Nadgee Nature Reserve Plan of Management acknowledged the value of his work:[4][5] Other significant long term studies which are still ongoing include long term monitoring of heathland bird communities by Harry Recher, and long term study of the impact of fire, drought and flood on forest-dependent mammals by NPWS [...].In 1990, Recher stood as a NSW candidate for the Australian Senate as an environmental independent with Irina Dunn, who was formerly a member of the House of Representatives for the Nuclear Disarmament Party.

As an intellectual leader in the field, Recher remained deeply committed to the contribution of science to policy for conservation and public understanding of ecology.
