Norfolk is considered to be a stronghold for this species.

Ancient semi-natural woodland; species-rich hedgerows; ancient trees and wood-pasture; and riparian habitats

Throughout county but distribution patchy. Main stronghold in Broads.

Dykes, streams and rivers.

Perhaps as numerous in Norfolk as any county, and relatively abundant in some areas such as north Norfolk.

Arable farmland and grazing marshes.

Occurs in most river catchments. Population is showing signs of increase.

Rivers and lakes

Coastal waters

Despite being a species of conservation concern in Norfolk, UK and Europe, the Barn Owl remains an iconic species of Norfolk farmland.

A very few pairs breed along the north Norfolk coast and in the Broads. Some winter visitors.

Large reedbeds

Sparsely distributed throughout the county, with important concentrations in the Fens and the North Norfolk Coast.

Open lowland habitats, such as farmland and grazing marsh

Patchy distribution often associated with light soils. Norfolk has always been an important area

Farmland

Breeds at nine main sites in Norfolk, in the north and east of the county. These sites support one-third of the UK population.

The best nesting sites consist of suitable areas of mixed shingle and sand, with plenty of marram grass or other vegetation nearby where the chicks can hide.

The 2004 national survey found 313 churring males in Norfolk.

Heathland and forestry re-stock areas.

The greatest concentrations are found on the northern, eastern, and south-western peripheries of the county.

Primarily associated with wetland habitats, similar to those used by sedge warbler.

Widespread breeding bird and winter visitor despite likely decline.

Arable farmland and rough grassland.

Nests in scattered locations across Norfolk. There are an estimated 660 pairs in the county.

Open woodland habitats; gardens and churchyards with mature tress.

Majority of UK pairs in Brecks, a handful of pairs in north-west Norfolk

Arable land on light soils and heathland

Relatively high numbers in Norfolk

Farmland, woodland parks and gardens

Summer visitor, across Norfolk. Availability of nest sites in new and older buildings is crucial to breeding success.

Buildings

Patchily distributed across the county, with main concentrations in north and mid-Norfolk and the Brecks.

Farmland.

Widespread, with core areas in the Brecks, north-west, mid and central Norfolk, and the Fens.

Associated with fertile, arable farmland in warm, dry situations.

The 1997 national survey found between 237 and 248 pairs of woodlark in Norfolk.

Heathland and forestry re-stock areas, particularly in Breckland.

Thinly distributed in Breckland, mid, and south Norfolk. Major decline in Broads

Ponds

Confined to five colonies.

Heathland

Rivers Wensum, Tat, Bure, Glaven and Yare

Clean, flowing water

Four sites in Broads, one on North Norfolk coast and STANTA in Brecks

Unpolluted calcareous water in well-vegetated marsh drains

Yare, Wensum, Waveney and in western rivers

Sediments in slow rivers

Broads and Thompson Common

Ponds and drains with unpolluted calcareous water

A few sites in Broads and East Anglian Plain Natural Area

Marshes including saltmarsh

Increasing number of sites in many river systems

Tall swamp vegetation

Numerous in a very few coastal lagoons

Saline lagoons

First described from Norfolk (1782). Seen sporadically since. Now at two or three sites

Roadside verges on light soils

Last recorded at Holme. Possibly extinct.

Unimproved grassland hay meadows

Now only one UK site in Brecks

Grazed Breck heath

Has been recorded at six sites. Now only known from one.

Roadside and parkland trees

Recorded at six or seven sites, but now only known at one

Calcareous flushes on fens

Has declined alarmingly in recent years, but still occurs in approximately 30 tetrads in Norfolk (mainly to the south of the county).

Largely restricted to the clay plateau.  Most often found on the margins of winter cereals.

In recent years, has been present at only two sites in Norfolk.

Semi-aquatic; grows in the muddy margins of shallow waterbodies and ephemeral pools.

Recorded from only five sites since 1950 and at only one site in 1997.

Light, open soil on extensively managed arable land or other disturbed ground, including field edges, tracks and sandy commons.

Now very scarce and recently seen only at Snettisham RSPB Reserve.

Typically occurs on light, chalky soils but at Snettisham is found on a shingle bank.

Occurs in 12 one-km squares in Norfolk; particularly abundant along a disused railway line at Gimingham.

Arable land, waste ground and sandy seashores.

Almost confined to Breckland; found at 17 sites between 1988 and 1999.

Forest rides; light, nutrient-poor, sandy soils.

Discovered in 1972 at Langmere, thought to have been introduced by ducks. Now extinct

Still waters

Three sites

Mown fens

Three populations at Potter Heigham (2008)

Ditches and dykes with quiet, clean water and high levels of light.

A few sites in the Broads, its only UK area.

Broads and newly-created turf ponds

Norfolk remains one of the plant's strongholds, with good populations in Broadland and the Ouse Washes.

Thrives in ditches and wet fens where water is kept open by occasional clearance.

Approximately 70 mature trees survive in Norfolk.

A tree of hedges and open spaces.

Recorded from Cranwich Camp, Gallows Hill (Thetford) and Roydon Common.

Found in grassland and among open scrub on chalk or sandy soils, often under stones.

Confined to the Brecks.

Sandy soils at the margins of agricultural fields.

Last recorded in 1996 at Bodney Camp, part of the Stanford Principal Training Area.

A species of disturbed ground. Appears to be associated only with flixweed (Descurainia sophia), which is believed to act as a food plant for the larvae.

Baltic, Convergent, Intermediate and Starry Stoneworts are all found within the Martham and Blackfleet Broads; the Bearded Stonewort is now believed to be extinct in Norfolk.

Stoneworts favour clean, clear water.

Two recent records from Norfolk (Cantley Marshes and Sculthorpe Fen); a species of alkaline water in pools, canals, ditches and the poached edges of ponds.

Recent research in North Norfolk has suggested a decline of 75% between the 1970s and 2008/9.

Found in freshwater systems, but characteristic of ponds and river backwaters.

Occupies seven river valley systems/waterbody areas in east Norfolk, with the majority in the Norfolk Broads.

Breeds in fen and grazing marsh dyke systems. Requires clean water, a rich aquatic flora and sufficient terrestrial space to hunt.
