Habitats

TVERC has mapped habitats in Berkshire and Oxfordshire using a mixture of field survey data and aerial photograph interpretation. Habitats have been mapped to identify S41 Habitats of Principal Importance (previously called UKBAP priority habitats) and JNCC Phase One habitats.

In Berkshire the whole county was mapped with funding provided by our Local Authority partners. New data has then been added to the dataset.

In Oxfordshire habitats have been mapped in designated sites and Conservation Target Areas plus mapping of woodland in the Wychwood Project area and all habitats in Cherwell District.

We have partnered with Bosqmap to allow us to use Bosqmap forms within MapInfo to allow easy and standard updating of habitat data and other attributes.

Natural England Single Habitats Layer Dataset (Priority Habitat Inventory)

Our data on some NERC Act S41 Habitats of Principal Importance (previously called UKBAP priority habitats) was updated and fed into national habitat inventories held by Natural England. Natural England have recently replaced these inventories with a Single Habitats Layer Dataset (Priority Habitat Inventory). While this incorporates some of our data this dataset is far less accurate than the TVERC habitats dataset for Berkshire and Oxfordshire and is not suitable for making decisions at a local level.

We strongly recommend that people contact TVERC for habitats information in Berkshire and Oxfordshire, by submitting a data request form , rather than using Single Habitats Layer from Natural England.

How do TVERC know what habitat is present?

TVERC have used aerial photographs and field surveys to identify and map habitats. The data also tells you how certain we are that the habitat has been correctly identified, using determination and interpretation descriptions.

What is S41 Habitat of Principal Importance?
(previously called BAP priority habitat)

UK Biodiversity Action Plan (BAP) Priority Habitats were those that were identified as being the most threatened and requiring conservation action under the UK Biodiversity Action Plan (UK BAP). These habitats are now listed in section 41 of the Natural Environment and Rural Communities (NERC) Act and are called 'Habitats of Principal Importance'. They are the most important habitats for wildlife.

They are protected from harmful development by the NERC Act and the National Planning Policy Framework.

What is Phase 1 habitat?

The JNCC Phase 1 habitat classification and associated field survey technique provides a relatively rapid, but crude, system to record semi-natural vegetation and other wildlife habitats. The system has been widely used and continues to act as the standard ‘phase 1’ technique for habitat survey across the UK.

What is IHS?

Integrated Habitats System (IHS) integrates existing classifications in use in the UK with particular emphasis on BAP Broad Habitat Types, S41 Habitats of Principal Importance (previously called BAP Priority Habitat Types), Annex 1 of the Habitats Directive and Phase 1. Standard habitat definitions from these classifications are combined into a hierarchy starting at the level of Broad Habitat Types, through vegetation communities to habitat-specific features, such as management practices.
