Blewbury Collage

The Natural Environment and Heritage theme aims to raise awareness and promote protection of Blewbury's architecture and special characteristics – including its springs and streams, trees, and downland.

Background

Blewbury can trace its geological history back 350 million years. However, most of its visible features are the product of weathering and erosion in the past 12,000 years, since the last glacial period. There is evidence that people have been living here for about 4,000 years.

The Natural Environment and Heritage theme aims to raise awareness and promote protection of the landscape of the village of Blewbury and surrounding land in the parish. It is a baseline project for sustainable development, and thus focuses primarily on the biodiversity and wildlife of its downland habitats, together with its springs and streams, trees, and village fabric. The theme also includes Blewbury’s architectural heritage, and the skills needed to sustain the special local character of the village. It is linked to other village activities such as the Local History Group and the Archaeology Group.

Poppies and Blewburton Hill

Special projects in the past have included Blewburton Hill, notably the book A View from the Hill, and actions related to the Parish Plan.

We welcome ideas and help for this broad theme. If you would like to get involved, or just want to be kept informed by email, please contact Mike Edmunds:mike e

This page covers a variety of activities:

Background information about Blewbury’s water sources, springs and streams is on a separate page.

 

Downland Project

Red kite

Blewbury is one of several spring-line villages, lying at the foot of a low escarpment forming the northern boundary of the chalk downs within the North Wessex Downs Area of Outstanding Natural Beauty (NWD AONB). There is a zoomable map showing the extent and boundaries of the AONB, which includes the entire village and its surroundings.

The southern part of the parish of Blewbury lies within this area of downland, much of which is given up to arable farming, although patches of land still retain characteristics of the original calcareous grassland which is one of the richest habitats in Europe. These remnants are being identified and studied for their intrinsic biodiversity. The area known as the Chalk Pit is an old chalk quarry with an ancient hollow way, Rubble Pit Lane, leading to it from the village. The quarry and the path contain a mosaic of habitats including lowland calcareous grassland, rank grassland, scrub and wooded areas. These areas together have been made a new Local Wildlife Site on the recommendation of the Berks, Bucks and Oxon Wildlife Trust (BBOWT).

The project was awarded a grant of £6057 by NWD AONB in January 2012. This has allowed the habitats to be managed and significantly improved by reducing the scrub and increasing the areas suitable for wildflowers. Where possible, the long grass has also been cut and removed in the autumn to give further help to the existing wildflower and insect populations.

Current activities

Rubble Pit Lane: This now a much improved scene. The area covered by Rubble Pit Lane, and the Chalk Pit at lower left, is outlined in red on the map below. The scrub has been greatly reduced where it was encroaching on the grass areas. The sections where the scrub and trees had already taken over completely were drastically cut back early in 2013 by Oxfordshire County Council (OCC) under their legal obligation to keep the lane open as a bridleway (photo). OCC collaborated closely with the project management, and the result is a wider, improved public bridleway and footpath with very much thickened hedges on each side giving much improved habitat for birds and other wildlife. The bottom two photos show the path as it was before (left) and after regrading (right).

The Chalk Pit: The dense scrub, mostly hawthorn, has been much reduced by cutting and then poisoning the stumps. The remaining bushes provide some shelter and feeding habitat for birds without shading the grassland too much. The photo at left is an overall view of this former chalk quarry. Autumn grass cutting (photo at right) has allowed a marked increase in many species of wildflowers.

Tickers Folly Field: This is an area of about 2.5 hectares of grass, owned by the village, which in the past has been mown short throughout the summer months. By agreement with the Parish Council, just over a fifth of a hectare is now under care as a wildflower meadow. Getting wildflowers to become established is a slow process, but more than twenty new species are to be found as a result of our efforts. Experiments with different methods of propagation are showing the way to better results. So far the best survival rates have been achieved with strong plants carefully planted and then watered as necessary.

In 2013 a new method was tried in an area of about 550 square metres. This has been scarified by Paul Taylor of ‘Trugreen’ at no charge to the project, so that the top layer of turf is lightly disturbed and ready to receive a mix of wild seed and some additional seeds of yellow rattle to combat the coarse grasses.

Growing plants from wild seed: The previous item is one part of an experiment to propagate downland plants from seed to re-populate areas and corners with downland flowers. The aim now is to work with fewer but stronger plants and to plant them out more carefully. As an example, about 500 one-year-old cowslip plants are ready to plant in the spring of 2014.

The photos show autumn gentian, a large skipper butterfly on field scabious, a meadow pipit’s nest on Rubble Pit Lane, and toadflax.

Living Churchyard: Churchyards are important sanctuaries for wild life. Some, such as St Michael’s Church in Blewbury, are especially valuable, having been reclaimed from ancient meadows or pastures. If they have never been ploughed or treated with artificial chemicals, the soil will be rich in the seeds of wildflowers. This project (supported by BBOWT and the Church and Parish Councils) won an award in 2001. There are four different habitats: hedgerow, wayside, woodland edge and ditch, and chalk meadow. The existing natural floral population has been augmented by other species and a sustainable mowing routine established. Currently, the maintenance routine is continuing and new native species have been planted. Coarse grass is still the main problem and yellow rattle will be introduced to reduce this.

Millbrook Project: the Cleve, springs and streams

Silt sampling

The Millbrook stream rises in the village as a series of springs along the chalk escarpment and, along with the downland, gives rise to the special character of the village. We aim to survey the whole stream within the parish boundary for its biodiversity and ecology. This is an ongoing project, since we have been monitoring the hydrology of the springs for 20 years to better understand the flow characteristics and water quality. These were affected by the groundwater abstraction at Blewbury Pumping Station, but with its closure in 2007 there is now the opportunity to restore the health of the stream and its banks. The project focuses initially on restoration of the Cleve, an invertebrate survey, and monitoring of water voles and mink eradication. (Photo: sampling silt from the Cleve to determine its origin, July 2011.)

There is a separate page with more information about Blewbury’s water – the downs, springs and streams.

Restoration of the Cleve

The Cleve is a dynamic spring basin, and was formerly the site of the Blewbury watercress industry. It is fed by over 20 discrete springs, and the location of these is important in design of improved flows and as foci for improving ecology. Over the past 40 years or so the Cleve has been neglected and thick silt has accumulated, greatly reducing its ecological status. It is now agreed to be important to restore flow through the Cleve through a channel network capturing the spring flows, grading into wetlands. As far as possible we wish to restore the Cleve to a near-natural state with attention to landscaping.

First-stage funding was obtained for this project, including the following:

Project status: September 2013

Despite the considerable amount of work so far undertaken, we have decided to call off – at least for the foreseeable future – any new work to restore and improve the Cleve. The current position is that all available data for the hydrology and ecology of the Cleve has been analysed as a basis for any future work. However, grant bodies advise that any funding will depend upon having outline consent from all riparian owners (those bordering the water). This is because the Cleve is a ‘common pool resource’ with multiple ownership. We have such consent, indeed positive support, from all but one of the interested parties. The one objector to the plans means that they must be put on hold, despite the fact that there is wide agreement from consultants and public bodies that the proposals represent the best way forward for restoration. An integrated solution for the Cleve as a whole, in which all village interests are represented, is essential. A wider village consultation would only be taken once owners’ agreement was secured; no further actions or expenditure can be undertaken without acceptance that this is a community project.

An extended summary of the work undertaken is given here (pdf).

Invertebrate surveys

We are beginning a systematic survey of the Millbrook, working with the Environment Agency and the Riverfly Partnership – we are now part of their national river invertebrate monitoring programme that records the numbers of insect larvae present, and therefore the overall health of river systems. In June 2011 a lecture and practical demonstration were given to Blewbury schoolchildren (photos), and public demonstrations of the field technique were given at the 2011 Blewbury Festival.

Water vole surveys and mink eradication

There have been recent sightings of water vole, and also mink, in the Millbrook. We are establishing a monitoring project with a view to restoring the former and eradicating the latter.

Village trees

The village has a diverse landscape with many fine trees. This important heritage should be maintained, and where possible the landscape enhanced by additional tree planting and maintenance. We are working with the Parish Council on issues relating to planning, and programmes to plant new trees as well as to remove or prune trees for health and safety reasons. The start of the project was to establish a good database of the tree population.

From 2007 to 2009 most substantial trees in the public realm within the village, i.e. those along roads, footpaths and other open spaces, were identified and measured. Their girth, spread, height, position, condition, importance and history have been recorded. We have recently surveyed many trees in private gardens. A survey of trees in the wider parish of Blewbury remains to be done. A photographic record is being maintained – the photos show a weeping ash, trees at the edge of the downs, and a 600 year old yew.

Trees are under threat from many sources including disease, vandalism, acts of God, and impending climate and environmental change. This survey provides a baseline against which future changes can be measured.

As part of the 2010 Apple Day (see our photo gallery), a survey of Orchards in and around Blewbury was completed and a booklet published. The photo shows most of the 57 or so apple varieties grown in Blewbury.

Village Skills Project

Blewbury, like many other villages in the Vale of White Horse, has a strong rural tradition and is slowly losing, or is in danger of losing, traditional skills. We are planning to start a re-skilling programme which will address not only the village fabric and buildings, but also encourage other ‘endangered’ crafts and pastimes. These might include bee-keeping and honey making, willow growing and basket making, coppicing, hurdle making and others.

Blewbury Wagon

We have recently supported the refurbishment of the Blewbury Wagon, a project related to Blewbury’s recent past, and its community and agricultural activities.

Together with the Local History Group we are recording the special architectural details of buildings (especially listed ones) and village fabric. A study of about 100 houses has revealed the wealth of beauty in brickwork, windows, doors, engravings, etc. The results have been written up and recorded photographically, and a local artists group will make its own contribution with drawings and sketches. This serves as a baseline study for understanding the skills and crafts upon which the village has depended in the past. It will also help with the next update of the Parish Plan.

It is hoped that this survey will help identify skill shortages for maintenance and repairs of historic buildings. Although most owners have so far had few problems finding skilled craftsmen, everyone is aware that specialist skills may not be available unless we can encourage new trades and apprentices. We will identify these skills shortages and look into how training schemes may be initiated, possibly with other local villages.

 

Dark skies and tranquility

Sky glow

Blewbury is a village which has maintained a policy of having no street lighting. Light pollution is, however, still increasing, leaving less and less countryside where we can enjoy seeing the stars. Much of Blewbury's light pollution is due to sky glow from Didcot and towns even further away. Light pollution is wasted light which also wastes electricity. Outside lights can contribute to sky glow, and can also create glare and light trespass affecting others.

We are working with the Parish Council towards reducing light pollution, by ensuring that any lights shine downwards, are no brighter than necessary for safety, and only come on where necessary. We actively support the British Astronomical Association's Campaign for Dark Skies.

According to the CPRE, tranquility is the quality valued most in the English countryside. They have drawn up criteria for tranquil areas and we fully support their work in this area.
