About Denis J Vickers

Denis' expertise includes the study of vascular plants, Odonata (dragonflies and damselflies), Lepidoptera (butterflies) and birds. He is a specialist in conducting habitat surveys, ecological impact assessments, habitat creation projects, biodiversity action plans and formulating management plans, particularly for urban sites.  He also has a great interest in ancient woodland history and ecology particularly in lowland England. Denis has undertaken a variety of ecological work accomodating a wide-range of clients and participating in a variety of projects.

Denis provided ecological expertise regarding the development of a Green Grid for the London Borough of Harrow (in north-west London) on behalf of Harrow Council; the linking of key green spaces is envisaged via a network of green routes, including tree-lined roadways, wildlife corridors, cycleways and walking routes. Other work for Harrow Council includes the formulation of ten management plans for Local Wildlife Sites in the borough and the production of a new Biodiversity Action Plan.

Prior to this Denis worked for the multinational green design company EDAW plc (now AECOM Planning + Design) between 2007-9 as Senior Ecologist having been involved with ecology and nature conservation for more than 20 years.


Whilst at EDAW Denis worked on Bedford River Valley Park Design Guidance for the Forest of Marston Vale The plan proposes a new 2.3 km long and 100m wide Olympic-sized rowing lake, supporting development and what will be England's largest new floodplain forest, as well as new multi-user paths, cycle trails, canoe courses and green energy projects like short rotation coppice.

Previously Denis worked for the London Wildlife Trust (LWT) as Habitat Survey Manager supervising and carrying out habitat surveys for the Greater London Authority. Whilst working in this capacity Habitat Surveys of the L B Hackney, part of Havering, Barking & Dagenham, Camden, Waltham Forest, Lewisham, Merton and part of Enfield were conducted over the summer periods of 2001-7.  Supervision/coordination of surveys of other London boroughs, canals and breeding birds of the capital's squares and gardens were also undertaken.

Between 1994-2003 Denis managed the Ripple Nature Reserve and Dagenham Parish Churchyard in L B Barking and Dagenham for the Trust. In 1999 he elevated the status of the Churchyard from a local dumping ground to a community asset - the vicar of the Church described the transformation as "from a jungle to a gem." That year the site achieved 3rd place in the prestigious 'London in Bloom' awards. In 2003 the site was awarded the Green Flag Award the first LWT site to do so!

1996 Denis kick-started work on 'biodiversity' in London when he produced the Regional Biodiversity Audit: Habitats in London for the London Biodiversity Partnership. This information was used in compiling the Partnership's London Biodiversity Audit vol. 1 (published in 2000). In 1994 he co-designed the Natural History Museum's Wildlife Garden (with Gary Grant and Mark Loxton) and subsequently formulated a management plan for the site's first three years.
