Landscape and setting

The site lies within the River Mole Biodiversity Opportunity Area (BOA). BOAs identify the most important areas for wildlife conservation remaining in Surrey and each include a variety of habitats, providing for an ‘ecosystem approach’ to nature conservation across and beyond the county.

Habitat distinctiveness

Medium distinctiveness grassland and scrub (option of medium distinctiveness ponds and woodland or high distinctiveness grassland, subject to demand).

Management plans (what we intend to add):

Majority of the site is semi-improved species poor wet grassland (Other Neutral Grassland in poor condition) which will be enhanced to species rich wet grassland (Other Neutral Grassland in good condition).

An area of improved species poor grassland (Modified Grassland in poor condition) can be transformed into a woody habitat, subject to demand from customers.

Hedgerows onsite will be enhanced by improving the species diversity of the shrubby species and plant standard trees along its length.

The river Mole riverbank will see an increase of natural features and diversity of features along its riparian zone. This will include creation of temporary pools, species rich grassland, trees, and shrubs.

Habitats are the measurement of biodiversity for a Biodiversity Gain Site, and we agree that they underpin the framework for nature recovery in the UK. We see habitats as a canvas to paint a vision of nature which truly embraces the local environment. To do this we deep dive into the species which are the building blocks defining these habitats and try to focus the habitat creation, enhancement, and management on furthering locally important species.

One of the target priority species within the BOA is Greater Water-parsnip which is locally extinct and declining rapidly across the UK. This Biodiversity Gain Site brings with it opportunities to re-introduce this locally extinct species of principal importance (priority species) to deliver the BOA objectives in Surrey.

Other priority species which the project will be benefiting, and which are of local importance include;

1. Barn Owls.
2. Stag beetles.
3. Reed Buntings.
4. Grass snakes.
5. Round fruited rush.
6. Striped Mayfly.

Nunthorpe, Middlesbrough

The site is currently an arable desert on poorly draining soils adjacent to a heavily canalised stream. The site will be taken out of agricultural production transformed to a scrub grassland mosaic. The scrub will comprise mixed native species and will eventually mature and be managed to have different age categories with areas of open space within it.

The scheme will create opportunities for new species to move in such as Reed Buntings and Sedge Warblers. It will also measurably reduce the amount of nutrients, micro plastics and other artificial chemicals entering the Solent.
