      Home Page  Conservation designations


The purpose of this page is to explore any issues affecting the conservation of wildlife in our area i.e. from Portchester in the west north to Denmead, west to Chalton and south to the coast around Nutbourne Bay.  If you are concerned about an issue that might interest others send me an e mail (click here).  I will restrict topics to those affecting conservation and exclude those which are more amenity related.

Nutrient pollution


Natural England (NE) has issued guidance on 'Neutral Nutrient' development in southern England i order to prevent more nutrients ending up in and causing damage to the Solent and Dorset coasts.  Havant have produced a position statement and Portsmouth an an interim Nutrient neutral Mitigation Strategy.

Otionsp include site based approaches ( i.e. sewage treatment and infrastructure improvements), managed urban drainage and off-site actions such as purchasing credits by taking land out of intensive agricultural use.

The Wildlife Trust's advice  proposes a nature based solution involving the acquisition and restoration of nature rich habitats on intensively managed farmland.  They have already bought a farm on the Isle of Wight and NE regards this as suitabkle as mitigation for some building of new homes.

Nitrates ( and phosphorus) are the main causes of the algae blooms that are harmful to wildlife.

Portsmouth's  strategy aims to reduce the amount of waste water sent to Budds Farm sewage treatment works and they believe this will create enough credits to build 518 new homes per year.  But they plan to build 584 a year!

Havant have bought Warblington Farm with a view to reducing the nitrate run off from the farm.

If these measures prevent increases that's good but it only goes so far.  It does not  actually improve the water quality.


Havant Thicket Water Storage Reservoir

The plans for a large reservoir north of Havant are being dusted off and reviewed now that approval to build the reservoir is anticipated.  The programme now is as follows

2018 Submission of planning application
2019 Early preparatory work
2021 Site preparation
2023 Embankment Construction
2026 Filling and Commissioning
2028 Completion

The reviews will include an update of the environmental assessment by new contractors.  The reserve is expected to have a range of amenity facilities including a visitor centre and nature 'reserve' area which will probably be managed by Staunton Country Park.
