5. Features,
objectives and prescriptions
The following important nature
conservation features have been identified and shown on map 2 in
Appendix 6:
1. Unimproved Neutral Grassland (G)
2. Fen (F), Upper Saltmarsh (SM) and Sea Club-rush
Swamp (SCR)
3. Lower reaches of a Chalk River (CR)
4. Woodland/Scrub: Riverine Woodland (RW);
Willow/Alder Scrub (W/AS); Woodland (W).
Feature 1 – Unimproved neutral grassland
Objective 1: To improve the diversity
of grassland and maintain grassland in favourable condition.
Current condition:
The unimproved grassland is in 4 areas: North and Central Meadow most
of which is at the second stage of the restoration process with several
populations of coarse grasses such as False Oatgrass, Tall Fescue,
Cocksfoot, Yorkshire Fog and Perennial Ryegrass still dominating the
sward. Although most of these grasses are good for grazing they also
have considerable wildlife value in that they provide a breeding ground
for Essex and large Skipper, Ringlet and Speckled Wood butterflies.
However, they should not be allowed to dominate quite to the extent
that they do at present since they tend to be invasive to the exclusion
of other more delicate wildflowers and grasses. Other invasive
wildflowers include Creeping Buttercup, White Clover, Hogweed and
Hemlock Water Dropwort.
There are several large patches of Bramble and a large Bramble bank on
the eastern boundary of the South Meadow (indicated on the map with
Br). Although Bramble is very important for wildlife it needs to be
controlled.
Plant communities identified by the HWT 1998 survey are:
MG1 Arrhenatherum elatius (False Oat-grass) grassland is described as
grasslands of high botanical nature conservation value, neutral
grasslands, dry tall-herb grasslands and is characteristic of ungrazed
grasslands and neglected meadows and pastures. This plant community
occurs generally over the site but especially in the North and Central
Meadows.
MG12 Festuca arundinacea (Tall Fescue) grassland described as grass
dominated inundation communities occurs on poorly structured and poorly
drained soils. This plant community occurs generally in all four
grassland areas of the site but especially in the SE corner of the
Central Meadow (Lumley wet area) and in the southern part of the South
Meadow.
Seven old meadow indicators and various indicators of saline influenced
communities including the nationally scarce Divided Sedge have become
established in a few small areas.
However, the distribution of several of the old meadow indicators such
as Pepper Saxifrage is rather spasmodic and can be difficult to
establish. Numbers of Ragged Robin, which likes ground that is moist
for at least part of the year, have fluctuated with quite high numbers
in 2004 but very much reduced in 2005.
Phased cutting as advocated in the second management plan was started
in 2003 with part of the grassland area cut by a contractor in July and
the rest in September. However, it was not until 2005 that the phased
cutting programme was refined even further with only about half of the
North and Central Meadows being cut by a contractor in late July and
the rest cut in late September. Other smaller areas such as the
Community area in CM1 were cut with the power scythe in May, a small
overgrown area of the Central Meadow (within CM2) in September and the
SE corner of the South Meadow was cut in October.
Because of problems with the group’s power scythe, the sedgy area north
of the Causeway had still not been cut in December 2005. Nor had the
Seagull Lane patch which has not been cut since 2003. Future annual
cuts need to continue this phased cutting programme but also need to
develop a mosaic cutting programme which gives a more varied structure
and is better for wildlife.
Prescription list:
1. Annual cutting regime
a) Continue with an annual cutting regime for North
and Central Meadows whereby a maximum of 50% of any one area is cut as
early as possible in July with a second cut in September/October. The
areas selected for early cutting to be varied each year.
b) Patches of uncut vegetation to be left to create a
mosaic effect to provide a food source for invertebrates.
c) Arisings to be left to dry out on the ground for a
few days before being collected up for removal. This gives vertebrates
and invertebrates time to relocate.
d) A hay mower rather than a flail or rotary blades
should be used whenever possible to avoid harming the wildlife.
e) The arisings when collected should in preference
be removed from the site rather than being deposited on predetermined
sacrificial sites on the margins.
f) Areas used for community events to be cut in May
and possibly also in July and
September as the occasion arises but these areas to be restricted to
the so-called Community area within CM1.
g) Seagull Lane patch to be cut every other year if
possible and no less than every 3 years.
h) South Meadow to be left uncut apart from annual
cutting of certain areas such as SE corner (see Feature 2 below).
2. Selective removal of invasive plants such as Hemlock Water
Dropwort from the north and central meadows.
3. Control the spread of Bramble which if not
controlled would eventually take over the grassland area. This will to
some extent be included in the regular mowing regime but will have to
be supplemented with additional clearance.
4. Margins – Plants such as Common Nettle and Great
Willowherb to be left on the margins as a valuable nectar source.
Native trees and hedges to be planted at suitable locations in the
marginal areas.
5. Occasional paths - to be cut regularly in the summer
months. This especially applies to the South Meadow particularly the
path along the Bramble hedge. These paths to be cut quite wide at
intervals by cutting bays along the path to provide micro-habitats.
6. Experimental area (1)
Seed a small experimental area of coarse grasses with Yellow Rattle
(Rhinanthus minor). This is an attractive, early-flowering plant with
pale yellow, cowslip-like flowers which is semi-parasitic on grasses
and can be used to suppress the more dominant grasses.
Feature 2 – Fen, Upper Saltmarsh and
Sea-Club Rush Swamp
Objective 2: To maintain and extend
areas of Fen, Upper Saltmarsh and Sea Club-rush Swamp.
Current condition
a) Fen: Great Pond Sedge is found in the boggy areas
along the Lumley Stream. This was identified in the HWT 1998 survey as
plant community S6, Carex riperia Fen. S6 is typical of mineral soils
alongside sluggish rivers or other open areas.
The area along the banks of the Lumley Stream is frequently inundated
with water of varying degrees of salinity since the stream is tidal up
to the cottages further north. The area inundated depends on the height
of the tide, the wind direction and the amount of rainfall.
This small area of Fen had been left largely unmanaged until late
autumn 2004. At this time, a large amount of arisings from the adjacent
grassland was dumped onto this area because of the problem of disposing
of these arisings. As a result of this, the area of Great Pond Sedge
has declined noticeably this year due mainly to the increase in ruderal
herbs such as Common Nettle and Michaelmas Daisy which like rich,
fertile soil.
b) Upper Saltmarsh: Also confined to a small area
north of the causeway. This area is also regularly inundated by
saltwater due to the proximity of the tidal Lumley Stream with a small
area of standing water in the SE corner (Lumley puddle).
This area is therefore damper and hence a rich and diverse range of
wetland plants remain including Ragged Robin, Water Mint, Distant Sedge
(old meadow indicator) and the nationally scarce Divided Sedge and
Saltmarsh Rush (indicators of saline influenced communities).
This area also has a large variety of late flowering plants such as
Fleabane.
Sea Club-rush swamp: a small area of regularly inundated land near the
south entrance with a large area of standing water especially in the
winter. Flora found in this area include Tall Fescue, Silverweed, Sea
Club-rush, Halberd-leaved Orache, Sea Couch and Divided Sedge (the last
4 plants are indicators of saline influenced communities).
Prescription list:
a) Fen
1. The area of Carex riperia Fen (area F on map 2 in
Appendix 6) to be protected and not used as a sacrificial area for
dumping arisings from other parts of the grassland.
2. Any increase in Common Nettle and Michaelmas Daisy
to be controlled by selective cutting/strimming.
b) Saltmarsh
Annual cut - The main Upper Saltmarsh area (area SM on map) north of
the Causeway to be cut at least once a year in October-November and
possibly also selectively in March.
Bramble, Nettle and Hemlock Water-dropwort – to be kept under control
by selective cutting.
Experimental area (2)
Plugs of wildflowers such as Ragged Robin to be planted in areas where
this plant has been recorded in the past to encourage colonisation of
this valuable plant.
c) Sea Club-rush Swamp
1. Annual cut -This area to be cut with a power
scythe in the autumn each year. The arisings to be removed and placed
on a sacrificial area of Nettles.
2. Bramble hedge on southern boundary to be kept
under control.
3. Experimental area (3) Bank in SE corner to be
scarified and planted/sown with suitable wildflowers.
Individual trees, e.g. Osier and other Willow sp. to be coppiced to
rejuvenate them.
Feature 3 – Lower reaches of Chalk River
Objectives for feature 3:
a) To maintain river
courses in favourable condition and to create new water bodies where
appropriate.
Current condition:
The River Ems is a reasonably clean chalk river according to a survey
carried out by Portsmouth University in 2005. Most of the flora and
fauna of the river and riverbanks are typical of a chalk river,
including a healthy population of Water Voles. Japanese Knotweed, an
invasive alien species, is increasing on the western riverbank near the
gasholder. Litter and other obstacles are regularly removed from the
river by volunteers.
The riverbanks are vulnerable to erosion by people and dogs. A fence
has been put up to restrict access to the western riverbank and a dead
hedge has been created at the back of the industrial estate to restrict
access onto the western riverbank further north.
The Lumley Stream is also thought to be reasonably clean although no
official surveys have been carried out. This watercourse is susceptible
to residential pollution since it runs along the western side of Lumley
Road through the front gardens of numerous residential properties.
Litter and other objects are regularly removed by volunteers.
Volunteers monitor fishing which is not permitted here. Kingfishers are
regular visitors to this area. Fish reported in the Lumley Stream are:
Brown Trout, Eels, Sea Trout, Flounder and Grey Mullet.
Prescription list:
1. Litter and other obstacles to be removed regularly
by volunteers.
2. Invasive plants such as Japanese Knotweed to be
eradicated by the Environment Agency.
3. Branches which fall across the river to be removed
by the Environment Agency.
4. In-stream vegetation (approx. 60%) to be removed
from the River Ems by the Environment Agency as part of their annual
river clearance and flood prevention programme. This is to be carried
out in August-September each year.
5. Felling of any dead Elms to be done according to a
tree management programme agreed with the arborist at HBC.
6. Suitable fencing and/or hedges to be erected to
protect vulnerable riverbank areas.
7. Unauthorised tree felling on the banks of the
Lumley Stream to be prevented by putting up notices and suitable
fencing.
b) To protect
habitats of endangered mammals
Current condition:
Both banks of the lower sections of the River Ems is home to a healthy
population of Water Vole (UK and Hampshire BAP species). The Mature
Crack Willows and other trees along both banks of the River Ems and in
Palmers Road copse provide a feeding and possibly a roosting habitat
for the Pipistrelle Bat and Serotine Bat (UK and Hampshire BAP species).
The ideal riverbank cutting programme, as advised by Debbie Miller and
Clare Bishop in their management plans is to cut short sections (30-50
metres) of riverbank on alternate sides on a rotational basis. The
Environment Agency carries out a green cut of the riverbanks each year
as part of their flood prevention programme with the aim of protecting
the Water Vole habitat.
This cut has been carried out in consultation with BMCG between 2000
and 2005 and as yet we have not succeeded in getting the optimum green
cut as outlined above.
A dedicated Water Vole signcase on the western riverbank in Palmers
Road copse informs dog owners that it is an offence under the CROW Act
to destroy the habitat of protected species such as the Water Vole. Dog
owners are also asked not to let their dogs go in the river during the
Water Vole breeding season.
Prescription list:
1. Only one of the riverbanks to be cut each year by
the Environment Agency according to a green cut programme agreed
beforehand between the EA and BMCG.
2. A metre of vegetation to be left along the water’s
edge of the riverbank to provide protection to Water Voles.
Access to the riverbank to be restricted by building dead hedges using
fallen and coppiced branches from other areas of the site.
Any trees in Palmers Road copse which have to be felled or pollarded
because they are a hazard to be kept to a minimum to protect the bats
that might be roosting there.
Feature 4 – Woodland/scrub
Objectives feature 4:
To maintain the diversity of native
woodland and scrub habitats and retain landscape and boundary diversity.
a) Riverine woodland
Current condition:
The line of mature Crack Willows, along both banks of the River Ems,
form part of the industrial heritage of the site. The management of
these trees has been neglected for many years. A number of these trees
are along the main path through the site and so constitute a safety
hazard. In addition to the Crack Willows along the riverbanks, there
are also several mature Ash, Alder, Sycamore and Hawthorn.
Prescription list:
1. An annual programme of pollarding to be agreed
between HBC’s arborist and BMCG with the aim of rejuvenating the trees,
removing the hazard of trees falling over the footpath and allowing
light to reach the woodland floor, thus enabling woodland flora to
flourish.
b) Scrub
Current condition:
There is a dense area of Willow scrub on northeastern boundary (Lumley
copse) which has never been managed and which provides the only really
wild area on the site. Roe Deer are known to go into this area and a
rare moss has been identified. This area is in West Sussex and for this
reason has not been included in the site’s SINC status.
Other areas of willow regeneration are found on the eastern banks of
the Lumley Stream and on the western boundary of the South Meadow along
the River Ems. In addition, occasional Willows have regenerated in the
North and South Meadow. Several of these trees are affected by
bacterial canker and the affected branches tend to break off during
stormy weather.
Prescription list:
1. Lumley copse to be left largely unmanaged apart
from some small-scale coppicing on the margins with the open grassland
area.
2. Other areas of Willow scrub to be controlled by
either coppicing or thinning. And by removing diseased branches when
they break off.
3. New areas of Willow regeneration within the open
grassland area to be controlled by removing the saplings.
4. Ash saplings, which grow within the open grassland
area to be removed.
5. Existing Ash saplings on the edges of the meadow
area to be pruned formatively and selectively.
c) Woodland
Current condition:
The main areas of woodland are in Palmers Road copse, in various
plantations (approx. 10-15 years old), newly planted areas and
individual tress (existing and new plantings) and are marked on the map
accordingly. A system of rotational coppicing is suggested for woodland
management to create a diversity of height structure within the canopy,
allowing light to penetrate the woodland floor. This would enable
woodland flora to develop and create a diverse habitat for many birds,
small mammals and invertebrates.
A smaller wooded area of mainly Elms on the banks of Lumley Stream is
infected with Dutch Elm disease.
Prescription list:
1. The large trees in Palmers Road copse to be
managed by HBC.
2. BMCG to advise HBC of any known trees or fallen
branches that may contribute to a hazard.
3. Large individual trees such as Silver Birch and
Oak to be pruned where necessary, if possible by BMCG. Any other
tree management work to be carried out by HBC.
4. Groups of Willows to be coppiced or thinned on a
rotational basis in the autumn/winter by both HBC and BMCG.
5. Newly planted trees to be mulched in winter and
excess vegetation removed in the summer.
6. Any new plantings to be native trees of local
provenance.
7. Restrict any future tree plantings to edges of
meadow or marginal areas such as Seagull Lane patch.
Consider the possibility of planting, for example a Hawthorn hedge,
and/or specimen tree to improve the attractiveness of this entrance.
Discuss the management of the dead Elm trees with HBC and devise a plan
to protect this wildlife area and improve its appearance.
Feature 5 – Attractiveness to visitors
Objective 5:
To maintain and develop the attractiveness
of the site for visitors insofar as this is compatible with the other
site objectives, the requirements of the law and other constraints.
Current condition:
After a period of intensive management and interpretation by BMCG with
support from HBC, the site is now very attractive to visitors.
· Interpretation boards with a pictorial map
painted by a local wildlife artist at two entrances and signcases at
three entrances with up-to-date information and photos about the
wildlife and conservation work carried out on the site. Leaflet boxes
have been fitted to these signcases containing free Visitors Guide
leaflets and leaflets about the group including a membership
application form. There is an additional signcase on the banks of the
River Ems near the new fence with information dedicated to the Water
Vole.
· Three sets of steps and a ramp have been
built to improve access onto the grassland area. All the main paths
have been laid with path gravel which has greatly improved access
especially for children and the elderly. The occasional paths are
always kept open during the summer and overhanging branches removed.
· Litterbins and doggy bins at the main
entrances and a seat on the causeway path in the centre of the meadow.
Volunteers and local residents regularly pick up litter and the river
is also regularly cleared of any litter or obstacles.
· Public events take place in the meadow
including a Wildlife Funday in May.
· Local and not so local schools make regular
visits to the site as part of their curriculum studies.
· Local natural history groups are also
regular visitors to the meadow.
· A kissing gate has been erected (December
2005) at the Seagull Lane entrance to improve access and the
attractiveness of the site.
These improvements encourage more people to visit the site as witnessed
by the visitor surveys the group has carried out.
The main problems now are dog fouling and occasional vandalism to the
signcases and doggy bins. The first is a source of conflict between the
various users. Not all dog owners clean up after their dogs and are
perhaps not aware that children use the site regularly and consider the
meadow part of their classroom.
This needs to be tackled creatively to avoid conflicts in the future.
The group plans to organise a competition for the local schools to
design a suitable notice to encourage dog owners to “Skoop their dog’s
Poop”. The winning notices will be put up at the main entrances to the
site.
Prescription list:
- Organise a competition for local schools to design a ‘doggy
notice’ to avoid conflicts between users.
- Extend the group’s policy of ‘zero tolerance to litter and
vandalism’ by finding a creative solution to the problem.
- Continue to monitor visitors to the site by organising Visitor
Surveys each year.
- Continue the programme of path and step maintenance.
- Continue to strim the edges of the main paths (by HBC) but only
at certain times of year after consultation with BMCG to limit damage
to wildlife.
- Continue to provide up-to-date information and photos of wildlife
and conservation work in the four signcases, annual report, bi-monthly
newsletters, fortnightly email notes and website.
- Continue to provide support for schools to make educational
visits to the meadow.
Long-term objectives
- Disabled access
There is no proper disabled access onto the site. The possibility of
creating disabled access from the south entrance is under consideration
by HBC. A key requirement here is that such an access must be in
keeping with the rural nature of the site.
- Wetland habitat
Enhance the variety of habitats and biodiversity of the site by
creating a wetland area in the South Meadow with a boardwalk to allow
wildlife observation.
- Valued landholding
Continue to improve the site as a valued part of the Borough’s
landholding with general appeal to visitors and widely recognised value
to the community.
The site is designated as a Site of Importance for Nature Conservation
making the future of this valuable wildlife habitat reasonably secure
but success on the ground depends upon the support of local people. The
potential of the wildlife resource to generate real added value to the
life of the local community and of the Borough as a whole needs to gain
general acceptance if it is to be truly secured. To help achieve this,
the very successful programme of activities such as walks, talks,
exhibitions, displays and workshops already initiated and organised by
the Brook Meadow Conservation Group forms an integral part of this
management plan.

work plan with details of work to be done at different times of the year
5.2.2 Work
programme over a 6-year period
5.3 Monitoring
5.3.1 Project
recording system
Systematic wildlife surveys carried out regularly each year are
necessary to provide a record of the wildlife in Brook Meadow. To
assess the effectiveness of management, e.g. grassland cutting regime,
changes in plant populations need to be recorded according to area. To
assess the effects of external factors, such as population cycles and
climate change, the data needs to be passed on to national and/or local
wildlife agencies such as Hbic, HWT, etc. Wildlife agencies require
records in a specific format, i.e. name of recorder, date, place and
details of what is recorded, to enable comparisons to be made.
Details
5.3.2
Progress reports
Reports to be made of all work sessions. Tasks to be carried out on
future work sessions, based on the Annual Work Schedule (Table Ia 2005
and Ib 2006), to be agreed at the committee meeting preceding these
work sessions. The tasks actually carried out to be recorded on the
Annual Work Schedule. A draft Work Schedule for the following year to
be drawn up and agreed each December. In addition, the work programme
over a 6-year period (Table II) to be adjusted and modified each
December.
A Tree Management report to be drawn up each year in December/January
after a site visit with the arborist at HBC and the work schedules
adjusted accordingly. The tree management report for 2005 is included
as Table III below.
5.3.3
Management Plan review
The current Management Plan to be updated annually and reviewed after 5
years, therefore in 2010.
