Dartford Parks - FPCR
The development of the Dartford park site
in East London by Prologis necessitated the
clearance of water voles from a footprint of
over 264 acres. A mitigation strategy was
designed to accord with the likely
requirements of the 2006 Water vole
Handbook and in handbook.
In 2004 130 captured animals were taken into
the captive holding facility of the DGC at Upcott
Grange in Devon. Provision had been made in the
site development plan for the future
establishment of new water bodies and the
retention of already existing water vole habitat.
There was no capacity to allow the water voles to
remain on site while active construction works
were undertaken. The mitigation strategy
therefore focused on trapping out the onsite
population completely to establish a captive
breeding programme which would have the
capacity to restore a significant population of
genetically variable water voles to the Dartford
park site once habitat restoration was complete.
Although habitat restoration was originally
programmed for 2007, delays to the construction
schedule coupled with the slow regeneration of
vegetation delayed this process until 2009. In
2009 150 captive bred voles were released into
the riparian edge habitats of Dartford Park.
The sites chosen for release were all selected
for friable soils and good vegetation cover.
This was followed by further population
reinforcement in 2010 with a further 71 voles
which were late litter juveniles from 2009. A
field sign survey in the Autumn of 2010
confirmed that a water voles population was
well established throughout the suitable
habitats present on site in Dartford Park.
