Flashcards in Abbotswood housing proposal Deck (13):


on edge of romsey, hampshire

land is former gravel workings

has had informal public access and has developed some conservation value

800 houses

raods and junctions

infrastructure- water, energy, flood control

shops, sports facilities, bus links



category of infrastructure projects

sechduel 2 under section 10b which gives threshold area for consideration of 0.5 ha the site is 52.4 ha

test valley borough council requested EIA


Zone of influence

abbotswood site

river test SSSI
mottisfont SAC

fishlake arboretum

cupernham and woodley

ganger farm


desk study

Natrual england contacted for details o fSSSI and hampishire biodiversity information centre (HBIC) consulted for any existing data help, incl designated sites and protected species records

old aerial photographs and easy ordinance survey maps were consulted to examine the historical land use of the site



statutory nature conservation organisation (1999): natural england, hampshire county council, EA

hampshier wildlife trust

great crested newts and development of a conservation area

SINC resulted from collection of ecological data for this proposal

nature conservation area


Site characteristics

rough grassland

hedge boundaries on banks with ditches some boundaries on banks with ditches, come boundaries residential and a cemetery

come mature oak woodlands

2 ephemeral ponds plus other ephemeral we areas

170 plants species (ore nationally scored)
small numbers of reptiles
no dormice


ground nesting birds
great crested newts



hampshire bat groups have 28 recorded roosts within 2km of the site

surveyors with bat detectors near potential bat roosts

6 species foraging on site or on boundaries 3 small pipistrelle reposts in oak trees site considered of local conservation value

destruction of some boundary areas for road access considered to be a significant adverse effect on feature of local value

no impacts on roosts other than temporary disturbance

minor term impacts possible from traffic and lighting



61 species on site

barn owl: protected on schedule 1 of wildlife and countryside act 1981, red data book species and an amber bird of conservation concern. only a single bird has been recorded and single bed recorded; no suitable breeding habitat on site

BoCC species recorded breeding on site include red species; skylark, linnet, song thrush, reed bunting, bullfinch and amber species: green woodpecker, dunk nightingale, stonechat, blackbird, lapwing, willow warbler, gold crest hawfinch


Birds: mitigation

trees and boundary features mostly retained

light pollution restricted at boundaries and by conservation area

nature conservation area to include an area of short grassland with limited public access from ground nesting birds


Great crested newts

protected under habitats regulation

leglisaltion prevents intentional killing or injury to individuals and deliberate damage or disturbance to their habitat

present in pond on site peak counts entering pond over 200 (over 100 is a large population according to NE guidelines)

probably of "county conservation value"


Newts impact

unmitigated: sever adverse effects few to :
habitat loss
predation by domestic animals
potential damage or pollution of breeding pong


Newts mitigation

designated SINC retained, with buffer zone and fencing
pond creation within conservation area, plus managed by local conservation wardens
on site ecologist to oversee some development phases
within developed area- vegetal wildlife corridors and amphibian tunnels under roads


Summary of ecological mitigation

protecting the most important habitats and protected species on site;
enhancing the biodiversity on site;
maintaining and improving the ecological connectivity across the site;
minimising the potential impacts from the proposed development upon wildlife.
