Dr Tony Whitbread, who retired as Chief Executive of Sussex Wildlife Trust in March 2018, has returned to take a leading role in nature conservation as President of Sussex Wildlife Trust.

He joined the Sussex Wildlife Trust in 1991 as Head of Conservation before taking on the role of Chief Executive Officer in 2006.  During his time, Dr Whitbread played a huge role as a conservation advocate, battling against road building, urban development, the potential expansion of Gatwick Airport and other countryside loss.

Simon Linington Honorary Secretary

Simon Linington

Simon became a trustee of Sussex Wildlife Trust in 2015. Following work as a plant breeder for a Lincolnshire seed company, he moved to Sussex in 1981 to work for the Royal Botanic Gardens, Kew at Wakehurst Place. Here, he helped develop a national and international plant conservation programme using long-term seed storage. This work culminated in the establishment of the Millennium Seed Bank. He retired in 2014 as deputy departmental head.

Though with a wide-ranging interest in natural history, his life-long passion has been birdwatching. This has given him a deep appreciation of the Sussex countryside and the challenges it faces. He has been a member of Sussex Wildlife Trust since 2013.

Alan Stewart Chair of Conservation Committee

Alan Stewart

Alan is Reader in Ecology at the University of Sussex, where he has been teaching and doing ecological research since 1993. Previously, he worked at Cardiff University, Rothamsted Experimental Station and RSPB.

He started bird watching aged eight and wonders why it took him until his late teens to discover his other interests in plants and insects. Locally, he researches ways to restore species-rich grassland habitats, especially for insects.

Alan is also involved in the conservation of glow worms (the South Downs being one of the strongholds for this species), especially the extent that they may be affected by artificial lighting at night. Alan chairs our Conservation Committee. He has been a member of Sussex Wildlife Trust since 1994.

Emma gave up commercial practice and went to volunteer at the Environmental Law Foundation where she was then given her first job in environmental law.

Emma is now married with two small children and left London six years ago to settle in Lewes.
