Survey of hedgerows at Barton Farm, Winchester

0 EXECUTIVE SUMMARY

0.1 Ecoscope Applied Ecologists were commissioned by Cala Homes to carry out a survey of the hedgerows on Barton Farm, near Winchester, to determine whether any of the hedgerows meet the criteria for protection under the 1997 Hedgerow Regulations (i.e. whether they are of national importance).

0.2 Hedgerow 11 is the only hedgerow to qualify as a nationally important hedgerow according to sections 7 & 8 of Part II of the Criteria of the 1997 Hedgerow Regulations.

0.3 Hedgerows 1, 8, 9, 10, 12, 18 and 24, are very likely to be regarded as locally important hedgerows (on at least a district level) on account of their species diversity and associated features.

0.4 Hedgerows 2, 17, 21 and 22 also have a reasonable species diversity but a low number of associated features.

0.5 Whilst other hedgerows around the site are not species-rich, they still provide valuable nesting and feeding habitat for a variety of wildlife species, and navigational corridors for species such as bats. In particular hedgerows 2, 3, 4, 12, 13, 14, 16 and 17 provide habitat for Birds of Conservation Concern Red List bird species. These could be considered to be ‘ecologically important’ and their retention and suitable management is recommended.

0.6 Whilst the species diversity of the hedgerows, in general, is relatively good in local terms, the number of associated features is generally low. In particular, few of the hedgerows support standard trees and the level of connectivity with other hedgerows is generally low. This is because the site consists mainly of large intensively farmed arable fields where some hedgerows have been removed in the past.

Survey of hedgerows at Barton Farm, Winchester

1 INTRODUCTION

1.1 Ecoscope Applied Ecologists were commissioned by Cala Homes to carry out a survey of the hedgerows on Barton Farm, near Winchester, to determine whether any of the hedgerows meet the ecological criteria (ie under sections 6 and 7 of Part II) for protection under the 1997 Hedgerow Regulations (i.e. whether any are of national importance).

1.2 A measure of statutory protection is afforded to hedgerows under the Hedgerow Regulations 1997, where their ecological and archaeological features are shown to be ‘important’. Removal of ‘important’ hedgerows requires consent from the local planning authorities, except in certain prescribed circumstances such as the need to gain access.

1.3 The importance of hedgerows can be assessed according to the criteria identified in Part II of Schedule 1 to the Hedgerows Regulations 1997. A hedgerow is identified as being ‘important’ if it has existed for 30 years or more and satisfies at least one of eight criteria. Five criteria apply to archaeological features and can mostly be addressed by scrutinising historical maps and records. The remaining criteria apply to ecological features and are listed below. This report assesses the ecological importance of hedgerows only.

1.4 A hedgerow is identified as ‘ecologically important’ if it satisfies one of the following three criteria:

• Criteria 6 : contain certain categories of species of birds, animals or plants listed in the Wildlife and Countryside Act 1981 or the British Red Data Books

• Criteria 7: The hedgerow includes:

(a) at least 7 schedule 3 woody species, on average in a 30 metre length;

(b) at least 6 schedule 3 woody species, on average in a 30 metre length and has at least 3 associated features;

(c) at least 6 schedule 3 woody species, on average in a 30 metre length, including a Black Poplar tree, or Large-leaved Lime, or Small-leaved Lime or Wild Service tree;

(d) at least 5 schedule 3 woody species, on average in a 30 metre length and has at least 4 associated features.

The associated features are:

(i) a bank or wall which supports the hedgerow along at least one half of its length;

(ii) gaps which do not exceed 10% of the length of the hedgerow;

(iii) on average, at least one tree per 50 metres;

(iv) at least 3 schedule 2 woodland species within one metre, in any direction, of the outermost edges of the hedgerow;

(v) a ditch along at least one half of the length of the hedgerow;

(vi) connections with other hedgerows, woods or ponds scoring 4 points or more (where a connection to another hedgerow scores 1 and a connection to a broadleaf wood or pond scores 2); or

(vii) a parallel hedgerow within 15 metres of the hedgerow.

• criteria 8: Run alongside a bridleway, footpath, road used as a public path, or a byway open to all traffic and includes at least 4 woody species, on average, in a 30 metre length and has at least 2 of the associated features listed at (i) to (vi) above.

2 METHODS

2.1 The hedgerows at Barton Farm were surveyed on the 16th of August 2002 to determine whether they are ‘ecologically important’ under the 1997 Hedgerow Regulations.

2.2 Woody species, field layer species, associated features and the average number of woody species per hedgerow were recorded on hedgerow recording forms. The recording form has been devised to record all features relevant to determining whether hedgerows conform to the 1997 Hedgerow Regulations Criteria.

2.3 In accordance with these regulations, regular 30m sections of each hedgerow were sampled i.e. woody species were recorded for 30m out of every 100m in order to sample the hedgerow in a systematic way. The average number of species for each hedgerow was derived by totalling the number of species recorded and dividing by the number of sections. This gives an average to compare with the Hedgerow Regulations criteria.

2.4 Only when the average number of species is 5 or more are associated features taken into account. An average of 5 woody species and 4 associated features are needed for a nationally important hedgerow. The only exception to this is when the hedgerow runs alongside a footpath or bridleway. In this case only 4 woody species and 2 associated features are needed. Hedgerows failing to meet national criteria may still have local importance.

2.5 Scientific names for plant species are not recorded in the main text but are included in the target notes for each hedgerow (Appendix 1).

3 RESULTS

3.1 Hedgerow 11 (see Figure 1 for location) alongside the public footpath is the only hedgerow which qualifies as a nationally important hedgerow. It meets the minimum requirement (for hedgerows running alongside footpaths) of an average of four woody species per 30m length and two associated features (Table 3.1). The associated features were: less than 10% gaps, three connections with other hedgerows and two connections with small woods (copses) at either end (i.e. good connectivity). The total number of native woody species was eight (see target notes). However it only just narrowly qualifies by virtue of its association with the footpath, and there are other hedgerows on the site which have an equal or greater diversity of species and associated features but do not run alongside footpaths. As a result they do not qualify as nationally important.

3.2 Hedgerow 12, in particular, has five species per 30m section and two associated features (four associated features needed for national importance when not alongside a footpath) but fails the national criteria because it does not run alongside a footpath. The total number of woody species was nine.

3.3 Hedgerow 24 also has four species per 30m and two associated features. The total number of woody species was seven.

3.4 Other hedgerows may also have a high number of species overall but the diversity is not always represented well in the 30m sections sampled, reflecting the limitations of the methodology.

3.5 Hedgerow 1, for example, has at least 13 native species overall, but has been heavily invaded by non-native species such as Norway Maple and Sycamore which outcompete other species and reduce the diversity of the hedgerow. The average number of species per 30m section (three) seems low considering that the overall species diversity is good. The hedgerow is a long one, running alongside a large arable field. It is possible that intervening field boundaries which would normally divide the length of the hedgerow have been removed giving a misleadingly high number of species because the hedgerow is so long. The hedgerow has only two associated features.

3.6 Hedgerows 9 and 10 alongside the small Beech wood also have good diversity. Nine and seven species were recorded in total (respectively) with an average of three species for both. The number of associated features was high (four) in both cases. These include: standard trees in the hedgerow, good connectivity to other hedgerows and the adjacent woodland, and less than 10% gaps. The footpath also runs alongside hedgerow 9.

3.7 Hedgerow 18, alongside the Council Yard, has a good species diversity, with eight species in a relatively short length (average of three species). Its value is increased by the fact that it runs alongside a footpath and also by the presence of an adjacent strip of species-rich calcareous grassland. It also has two other associated features – less than 10% gaps and good connectivity with other hedgerows and small woodlands.

3.8 Hedgerow 8 has a high number of species overall (seven) considering its short length (average 3-4) and two associated features: less than 10% gaps and good connectivity with other hedgerows and small woods.

2) Connections with 3 hedgerows and 2 woods

3.9 Hedgerow 2 has a good species mix - ten species overall and an average of three species. However, it becomes very gappy towards its eastern end and only has one associated feature.

3.10 Hedgerow 17 has a reasonable species mix, with six species in total (average of three per 30m section) but has only one associated feature.

3.11 Hedgerows 21 and 22 have four and six species in total respectively with an average of three species each. There are no features associated with either hedgerow.

3.12 All other hedgerows are relatively species-poor and / or very gappy. There are also garden edge hedgerows which are mainly ornamental and therefore comprise mostly non-native species. Other field boundaries either small woods or open edges have been target noted. The woods are described in the Phase 1 survey.

3.13 Evaluation of the hedgerows with respect to criteria 6 of the Hedgerow Regulations (1997) suggests that some of the hedgerows may be ecologically important as a result of the presence of declining bird species. No bird species listed on Schedule 1 of the Wildlife and Countryside Act 1981 were recorded on the hedgerows during the breeding bird surveys. However, a number of Red List (Birds of Conservation

Concern, BoCC, Gregory et al., 2002) bird species have been recorded on or near hedgerows within the site (Hedgerows H2, H3, H4, H12, H13, H14, H16 and H17; see Ecoscope, 2002 for further details). These are species whose breeding population or whose breeding range has contracted by 50% or more in the preceding 25 years. The Hedgerow Regulations criteria refer to the 1990 Red Data Birds in Britain which is now out of date and consequently the BoCC criteria may be more applicable in this situation. Consequently, hedgerows supporting BoCC Red List species could be considered to be ‘ecologically important’ and their retention and suitable management recommended.

3.14 Due to the nature of the surrounding habitat, it is thought unlikely that any of the hedgerows provide habitat for any species listed on Schedule 5 or 8 of the Wildlife and Countryside Act (Ecoscope, 2001). Although bats (listed on Schedule 5) were recorded flying along several of the hedgerows, none of the hedgerows is considered likely to support bat roosts

4 EVALUATION

4.1 Hedgerow 11 is the only hedgerow to qualify as a nationally important hedgerow according to the 1997 Hedgerow Regulations.

4.2 Hedgerows 1, 8, 9, 10, 12, 18 and 24 are likely to be locally important hedgerows (on at least a district level) on account of their species diversity and associated features.

4.3 Hedgerows 2, 17, 21 and 22 also have a reasonable species diversity but a low number of associated features.

4.4 Hedgerows 2, 3, 4, 12, 13, 14, 16 and 17 currently provide habitat for BoCC Red List bird species.

4.5 Whilst other hedgerows around the site are not species-rich, they still provide valuable nesting and feeding habitat for a variety of wildlife species, and navigational corridors for species such as bats.

4.6 Whilst the species diversity of the hedgerows, in general, is relatively good in local terms, the number of associated features is generally low. In particular, few of the hedgerows support standard trees and the level of connectivity with other hedgerows is generally low. This is because the site consists mainly of large intensively farmed arable fields and it is likely that some hedgerows have been removed in the past.

4.7 Species such as Beech, Dogwood, Spindle, Privet and Buckthorn, all of which were common in these hedgerows, reflect the calcareous soils.

5 RECOMMENDATIONS

5.1 Hedgerow 11, which is nationally important, and runs alongside the footpath, should be retained. Permission is needed from the Local Authority for the removal of hedgerows deemed important under the Hedgerow Regulations 1997.

5.2 Hedgerows 1, 8, 9, 10, 12, 18 and 24 are also relatively good hedgerows (of at least district value) and are strongly recommended for retention. Hedgerows 9 and 10, in particular, run alongside a bridleway and mature Beech wood. These hedgerows are not species-rich but provide valuable wildlife foraging and habitat.

5.3 Hedgerows 2, 3, 4, 12, 13, 14, 16 and 17 currently provide habitat for BoCC Red List bird species and therefore should be retained.

5.4 As far as possible, all other hedgerows should be retained as they have value as habitat for wildlife. In addition, their value could be enhanced by suitable management (e.g. replanting of gaps, reduced cutting frequency, rotational cycle of laying / trimming, etc.) and additional planting. In particular, standard trees are currently lacking from the hedgerows and would be beneficial.

H11

This hedgerow just meets the criteria for national importance by virtue of its proximity to the footpath which runs parallel to the hedgerow. Such hedgerows which have at least 4 species on average in a 30 metre length and at least 2 associated features qualify for national importance. This hedgerow meets the minimum criteria of 4 species per 30m and 2 associated features – namely less than 10% gaps, three connections with other hedgerows and two connections with small woods (copses) either end. However, it only just narrowly qualifies.
