TOMORROW (Tuesday, 24 February) has been described by environmental campaigners as a defining day for Thurrock's struggling wildlife 

Wildlife charities, Essex Wildlife Trust and Buglife, are worried that planning decisions due to be made on Tuesday (24 February) could mark a tipping point for the borough's unique wildlife, with irreversible losses of species. 

The charities are calling on Thurrock Council's planning committee which meets tomorrow to recognise the national importance of Thurrock wildlife by taking a bold step and preventing further destruction of its network of nature sites. 

They are highlighting the impact work on the planned Tilbury 3 port and the creation of a new quarry and landfill site in East Thurrock will cause. 

Campaigners say, despite its small size, Thurrock is home to nationally important populations of invertebrates and other scarce wildlife. 

These species have thrived on its mosaics of coastal habitats and its unusual, flower-rich brownfield sites created by its industrial history and its location on the south-facing bank of the Thames Estuary. 

They say: "The network of Local Wildlife Sites (LoWS) in the area recognises this and provides the local framework for Essex's recently published Local Nature Recovery Strategy (LNRS). However, despite this, LoWS still have little protection in the planning system. 

"With so much development pressure on this small corner of the historic county of Essex, there has been progressive loss of sites across this network in recent years to both housing and industrial expansion.

"Over half of wildlife-rich brownfield sites in the Thames Estuary identified between 2005 and 2007 were either lost or subject to planning permission in just a six-year period. 

"Since then, pressure on wildlife-rich brownfields has only intensified and this includes high profile habitat losses to the Tilbury 2 port expansion and now, despite local residents' and the Council's objections, more wildlife sites are ear-marked for destruction to make way for the Lower Thames Crossing.

"In Thurrock, the next few months could also see more destructive proposals considered, including for the Google-led Thurrock Data Centre on the Arena Essex Local Wildlife Site, which is the target of a petition signed by over 30,700 supporters to date." 

Tomorrow planning councillors will be asked to make a decision on the latest Port of Tilbury expansion, Tilbury 3, which would see the loss of its unique ash-fields of Pulverised Fuel Ash (PFA), which are part of the West Tilbury Marshes LoWS.

Just three miles up the road, there are plans to fill in and destroy the special flower-rich sand terraces of Buckingham Hill Pit LoWS, as part of wider quarrying plans in the area. 

Despite their protection under the Thurrock Local Plan and their essential role in the future success of Essex's 'Local Nature Re3covery Strategy' both applications are recommended for approval recommended, despite objections to the applications from a range of other organisations, including the RSPB, Essex Field Club and Essex Badger Protection Group, and alongside over 1,100 local objections to Buckingham Hill Pit. Three local councillors have been permitted to speak at the meeting adding their objections on behalf of residents.

Essex Wildlife Trust and Buglife argue that significant changes need to be, and can be, made to both planning applications. 

A statement says: "We ask that the Council's planning committee recognises that this is now the time to act to prevent these completely avoidable losses of sites and to move from last-minute prevention to forward-looking district-wide nature conservation plans to match the increasing pace and scale of development pressures.

The Shrill Carder Bee

"If Thurrock's planning committee decide to follow the recommendation for approval, it would be a bitter blow to Thurrock's wildlife, which includes special species like the Shrill Carder Bee (Bombus sylvarum), the Critically Endangered Stripe-eyed Paragus hoverfly (Paragus albifrons) and the Endangered Wall Butterfly (Lasiommata megera).

"A masterplan for the recovery of Thurrock's unique wildlife is urgently needed, with the Council working collaboratively with wildlife experts and the local community, putting it firmly on the national stage as an example of a Local Nature Recovery Strategy (LNRS) in action."

Dr Jeremy Dagley, Director of Conservation for Essex Wildlife Trust, and Jamie Robins, Programmes Manager for Buglife, have made representations of their views to the planning officers and councillors ahead of tomorrow's meeting.

Dr Jeremy Dagley says: "You cannot keep building on your best wildlife sites and expecting species to survive. 

"Despite responsibilities to enhance biodiversity, written into legislation, losses of unique, nationally important insect populations are being treated as acceptable collateral damage. 

"There is no coherent master planning that addresses the specific needs of this irreplaceable wildlife and no acknowledgment that these species need a network of nature sites. 

"The proven Lawton Principles of 'bigger, better, more joined up', embedded in Essex's Local Nature Recovery Strategy, which has the full support of all local councils, including Thurrock, are not being followed. Now it is the time to act to change this."

Mr Robins adds: "We are seeing so much irreplaceable habitat being lost to short-term thinking and disjointed decision-making. Not only are we losing key sites, but we're relying on unproven habitat creation techniques in the hope of creating suitable habitat down the line. 

"It won't be long until there is nowhere for some of the Thames Estuary's species to go and they are finally pushed over the edge."
