Southwest Environmental Limited was instructed by a planning consultancy to prepare a Preliminary Ecological Appraisal (PEA) for a proposed residential development in Wickford, Essex[cite: 4]. The site is located within the jurisdiction of the local planning authority in Essex[cite: 4]. The proposed development encompasses the erection of two chalet bungalows, alongside associated amenity space and parking facilities[cite: 4]. This ecological assessment was completed with a short lead time to facilitate the applicant’s planning submission schedule.

Methodology and Baseline Habitat Survey

A desktop review and field survey were conducted by a Project Ecologist[cite: 4]. The habitat classification was mapped following the standard methodology set out by the UK Habitat Classification (UKHab)[cite: 4]. The survey identified the site primarily as modified grassland featuring a heavily maintained, short sward[cite: 4]. Additional habitat features recorded on the site include a small area of sparsely vegetated land, a sealed surface paving area, and a line of trees situated along the northern boundary[cite: 4].

Protected Species Assessment and Statutory Compliance

The site was assessed for its potential to support protected species in accordance with the Wildlife and Countryside Act 1981 and the Conservation of Habitats and Species Regulations 2017[cite: 4]. The appraisal concluded that the site has a low likelihood of supporting bats, reptiles, mammals, and amphibians[cite: 4]. This is primarily due to the heavily managed nature of the grassland, the open exposure of the site, and a lack of suitable microhabitats or roosting features within the small trees[cite: 4].

The line of trees does present a high likelihood for supporting breeding birds and common invertebrates during appropriate seasons[cite: 4]. To ensure compliance with national legislation protecting nesting birds, any vegetation clearance or tree felling must be undertaken outside the typical bird breeding season of March to August, unless preceded by a nesting bird check conducted by a qualified ecologist[cite: 4].

Site Evaluation and SSSI Proximity

Desk studies indicated that the site is located within the Impact Risk Zone of Influence for the Crouch and Roach Estuaries Site of Special Scientific Interest (SSSI)[cite: 4]. This SSSI is designated for its intertidal mud, saltmarsh, and grazing marshes, which support internationally important numbers of Dark-bellied Brent Geese[cite: 4]. Due to the low biodiversity value of the proposed development site, its former agricultural nature, and poor habitat quality, the project is anticipated to have a negligible effect on the SSSI[cite: 4].

Ecological Recommendations and Conclusion

The site is evaluated as having low nature conservation value at a county or district level[cite: 4]. Consequently, no further Phase 2 protected species surveys are recommended for this project[cite: 4]. To achieve localized biodiversity enhancements, the implementation of native pollinator plant species, bat boxes, and bird boxes has been formally advised within the site plan[cite: 4].

How many BNG Credits per Acre?

How many BNG Credits per Acre?

If you are considering giving up some of you farm land for BNG credits, then of course you will need to know how many BNG credits you will get per acre. The land you are giving up for BNG will be out of use for many years and as such it is only right to investigate the returns you might expect.

BNG Credits are created by changing land from one use to another. For example a field to woodland, or some low lying meadows in to wetlands.

Not Just “How Many”

The first thing to realize is that it is not just a case of “how many”. As with wine or stamps the price of credits varies based on “distinctiveness“. Grassland may have quite low “distinctiveness”, whilst a lake would have very high distinctiveness. This can affect the price of each credit by 400%. (£40,000 to £200,000 or more).

Wetlands are a Very Good Option for BNG

But. How Many BNG Credits per Acre?

The short answer might be about 1 BNG Credit per Acre. Or 2 BNG Credits per Hectare.

This is based a few real world examples we have worked on where say 4 hectares of marginal land yielded around 7 BNG Credits.

But of course it is not that simple. The credits come from improvements in biodiversity. So if you start with good bio diversity (say scrub) then you will gain less when you “upgrade” to woodland.

Your best possible “yield” would be to upgrade mono-cultural farmland to something like a swamp or lake. But in terms of profit (especially in the long term) perhaps it is better to use scruffy marginal land and make fewer credits.

A last word. If you are think perhaps you could “tidy up” an area and then re-wild it in a year of two remember that what you do is all being recorded by satellites (google earth), and part of the process if proving that the land has not recently been changed.

Prices Can Vary Per Unit
