It will provides decision makers, especially those involved in planning with an evidence base to inform decisions about new development. It will also form the basis for funding to enhance biodiversity.
The full document and map can be found at:

Part 1: A description of the strategy area and its biodiversity (PDF) – A concise overview of the LNRS area, outlining its key landscapes, habitats, ecological features, and current biodiversity condition, providing the baseline context for recovery action.

Part 2: A statement of biodiversity priorities and species priority list (PDF) – The definitive list of priorities and potential measures that together will deliver a thriving, connected and wildlife-rich Surrey.

Part 3: The Local Habitat Map – An interactive map showing:

Areas of Particular Importance for Biodiversity (APIB) – Areas already identified as being of particular importance for biodiversity, including nationally and internationally designated sites, local nature reserves, local wildlife sites, and irreplaceable habitats.
Areas that Could become of Importance for Biodiversity (ACIB) – The area outside of the APIB identified as having the potential to deliver the greatest benefits for nature if targeted potential measures are implemented, helping expand and connect existing high‑value habitats.
Potential Measures – Areas where proposed specific nature recovery actions should be delivered to best achieve LNRS priorities, identifying locations where targeted measures can restore or enhance biodiversity.

The Local Habitat Map is of particular importance. It shows areas of highest biodiversity significance and areas which have the potential to become significant for biodiversity. Figure 1 provides an extract from the map for the area covered by the 4Bs Biodiversity Initiative. The most significant areas from a biodiversity perspective are coloured in dark green. In the 4Bs these are ancient woodlands and chalk grasslands of the North Downs, and other fragments of ancient woodland dotted through our landscape there are also a number of veteran tree locations.

Areas with the potential to become significant from a biodiversity perspective are concentrated along the scarp slope of the North Downs, which is currently mostly farmland – arable, pasture and grass crops. Other areas highlighted are along the River Mole and its system of tributaries.

Of particular interest to the 4Bs biodiversity initiative is the area in and around Tranquil Wood which has both a high value ancient woodland and an extensive area which has the potential to become significant for biodiversity.

The first two weeks were fairly typical - cool - but over the last two weeks of May there have been winds, heavy rain and searing heat, which has had a significant impact on my bird records both in terms of bird activity and of course my willingness to go outdoors to survey. During May the numbers of birds recorded singing or spotted during the survey walks were reduced across all four habitats but most significantly on the open farmland and single canopy woodland in the spinney.

Although bird sightings were reduced in our garden and on the riparian walk the impact on bird activity was greatly reduced by the level cover provided by dense scrub, shrubs and trees. The validation of this thought process was reinforced by the fact that those fewer birds recorded on farmland and spinney were clearly linked to hedgerows and small patches of dense understorey. This is ironic in context of National Hedgerow Week at the start of the month… hedgerows are a man-made replica of dense scrub cover once naturally occurring across the English countryside before land was cleared for large scale arable fields.

Although I’ve not yet finished surveying for this season, so far I’ve recorded a total of 55 species of bird across all four of my survey routes, it’s clear that 16 species regularly feature in most surveys… Wood Pigeon, Greater-spotted Woodpecker, Wren, Dunnock, Robin, Blackbird, Blackcap, Chiffchaff, Great Tit, Blue Tit, Magpie, Jackdaws, Carrion Crow, House Sparrow, Pheasant and Ring-necked Parakeet. The key feature of common across our local landscape that supports these birds are the ancient trees, dense scrub habitats and mature hedgerows that provide food, shelter and nest sites.

Here is my data collection sheet for May

Walk any lane in Betchworth or Buckland in May and you will know, even before you see it, that hawthorn is in bloom. The scent arrives first — heavy, sweet, faintly medicinal — and then the hedgerow comes into view, its branches smothered in white blossom so dense it looks, from a distance, like snow lying sideways on the field margins. For a few weeks each spring, our hedges announce themselves to anyone paying the least attention.

This week is National Hedgerow Week, and it feels like an appropriate moment to say something about the hedges that help shape the character our parishes — and to notice, properly, what they do.

Hedges are not just boundaries
It is easy to take hedgerows for granted. They mark field edges, they line the lanes, they have always been there. But the Tree Council — whose National Hedgerow Week initiative draws attention to these remarkable features each year — makes a point worth dwelling on: hedgerows are essentially formed from trees. The hawthorn, blackthorn, field maple, hazel, elder and dogwood that make up our local hedges are not merely hedging plants. They are trees in their own right, with all the ecological significance that implies.

Britain's hedgerows collectively run to hundreds of thousands of miles. They form the largest semi-natural habitat network in the country — a web of woody corridors connecting woodland fragments, farmland and urban green space across the landscape. For the wildlife that depends on them, they are simultaneously shelter, food source, nesting site and safe passage through an otherwise fragmented countryside.

What our hedges are doing right now
In the 4Bs our hedges are working hard. The lanes and roads between the village and the North Downs carry some of the oldest hedgerow fabric in the area — mixed species hedges with field maple, hazel, spindle and dogwood alongside the hawthorn and blackthorn, their species diversity a rough indicator of their age. The rule of thumb among ecologists is that each additional woody species in a thirty-metre stretch represents roughly a century of hedgerow history. By that measure, some of our parish hedges are medieval.

Those hedges are doing something measurable and important right now. They are capturing carbon in their woody biomass and roots. They are slowing surface water run-off across the slopes of the Downs, reducing the flood risk to the village below. They are providing the dense, thorny nesting cover that species like yellowhammer, whitethroat and linnet — all of them in long-term national decline — still find in well-managed mixed hedges. And in the week or two either side of hawthorn blossom, they are among the most important insect habitats in the landscape, supporting the early-season pollinators on which our fruit trees and wildflowers depend.

Hawthorn: this year's focus
The Tree Council has a particular focus on hawthorn for 2026 — and it is easy to see why. Hawthorn is the backbone of the British hedgerow. It is also one of our most ecologically generous native trees: its blossom feeds hundreds of insect species in spring; its dense, spiny growth provides some of the most secure nesting cover available to birds; its berries — the haws — sustain fieldfares, redwings and thrushes through the winter months when little else is available.

But hawthorn faces real pressures. Climate change is altering the timing of its flowering, creating mismatches with the insects that depend on it. Disease pressure is increasing. And decades of hedge removal, flailing at the wrong time of year, and the gradual loss of traditional hedge management have reduced both the extent and the quality of hawthorn habitat across the country.

The Tree Council is running free online talks this season to help people understand the threats hawthorn faces and how communities can contribute to knowledge about its resilience. If hawthorn matters to you — and after a walk down any Betchworth lane in May, it is hard to see how it could not — it is worth joining one.

What we can do
Our hedges are in reasonable condition compared to many parts of lowland England — but reasonable is not the same as thriving. The pressures on farmland hedgerows are real: intensive cutting regimes that prevent flowering and fruiting, the gradual loss of hedgerow trees as old specimens are not replaced, and the incremental narrowing of hedge bases through repeated cultivation.

As a community, there are things we can do. If you manage a garden boundary or an orchard hedge, consider cutting only once every two or three years and leaving the berries for winter birds. If you are planting a new boundary, choose native mixed species — hawthorn, blackthorn, field maple, hazel — rather than the laurel or leylandii that dominate so many suburban edges. And if you are a farmer or landowner with hedgerows on your land, the Sustainable Farming Incentive now includes well-funded options for hedge management and restoration that are worth exploring.

The Betchworth and Buckland Nature Trail passes through and alongside some of our best local hedgerow habitat. In National Hedgerow Week, it is worth walking it slowly, looking at what is in the hedges rather than past them, and thinking about what those woody tangles of hawthorn, blackthorn and field maple are quietly doing for this landscape — and for us. This photo of the of the hawthorn and blackthorn hedge along the path north of the Betchworth Post Office is a great example. It leads to older and more mature hedges along the A25.

This Sunday, May 3rd, something extraordinary will happen at 5am in the fields and lanes around Betchworth and Buckland — and almost nobody will be awake to hear it.

It's International Dawn Chorus Day once again, the one morning in the year when people around the world are invited to step outside before sunrise and listen. What they hear is one of the most astonishing natural performances on earth: the dawn chorus, the great collective outpouring of birdsong that erupts in the half-light of an early May morning and builds, layer by layer, into a full orchestral spectacle before most of us have even opened our eyes.

It begins in near-darkness. Song thrushes, blackbirds and robins are the opening soloists, staking their claims in the still, cool air when sound carries furthest and rivals are listening hardest. Then the wrens add their improbably loud rattle, the chiffchaffs start their rhythmic two-note call, the blackcaps deliver their rich, accelerating warble, and gradually — tit by tit, warbler by warbler — the whole neighbourhood joins in. By 6am, if you are standing in the right spot, the air around you is alive with the overlapping songs of a dozen or more species singing simultaneously at full intensity. There is nothing quite like it.

This year we are establishing a Betchworth and Buckland Nature Trail, to help connect people to nature and encourage us to appreciate the biodiversity that surrounds us. Our first project is to record the dawn chorus at 12 locations along the route and using the Merlin bird identification app reveal exactly who is singing and where. The result is a dawn chorus sound map of our local landscape. There is no substitute for being immersed in the dawn call but if Sunday's alarm feels like a step too far, our Nature Trail Dawn Chorus Sound Map sound map is waiting for you.

NB It looks like it will rain early Sunday morning but don't worry you can experience the Dawn Chorus on a dry morning any time this week.

This last week has been one of significant change on my daily bird surveys as the landscape and climate go through a significant change. Firstly, the farmer has ploughed the fields, which initially brought earthworms to the surface that provided a glut for corvids (crows, jackdaw & magpie) and buzzard but now seeded and rolled the fields leaving a barren brown wasteland. The skylark have retreated to short grassland covering the restored quarry and landfill site in front of the Post Office. This has caused a significant drop in records for the field habitat.

The second event of the end of April is the return of winter migrants, various species of warblers, closely followed yesterday by a Cuckoo (Cuculus canorus) that lays her eggs in their nests calling for a mate. The warblers and their allies are well represented in my surveys with records of five of the 13 species of warbler that regularly visit South East England – Garden Warbler, Blackcap, Lesser Whitethroat, Willow Warbler & Chiffchaff love the dense scrub of the River Mole Valley. Of their allies I’ve recorded Goldcrest & Firecrest in our garden, as well as the woodland and riparian sections of the walk. As yet I’ve not managed to record any flycatchers in this area. My updated species list is shown below.

Right the cuckoo my bird of the week.

]]><![CDATA[April without the showers Paul Ritchie]]>Tue, 21 Apr 2026 23:00:00 GMThttps://www.biodiversitypark.uk/blog/april-showers

We've experienced a significantly drier-than-usual spring. Broadly speaking the weather was milder during April, although we have had a couple of late frosts and a few blustery days but not so many showers. I added 3 more species to my list of wild bird species with Moorhen calling from the River Mole on the riparian walk and a Serin heard and seen in the large sallow growing in our ancient hedgerow. The highlight however, was hearing and seeing a Gray Wagtail (left) at our garden pond, which I recently cut back some of the over-mature vegetation to reveal open water making it more attractive to aquatic insect species such as pond skaters, diving beetles and midges.

The finches are well represented in my records with Chaffinch, Linnet, Redpoll, Goldfinch, Greenfinch, Siskin and Serin all being sighted and recorded across a range of habitats in the 4Bs area. I chose the Goldfinch (Carduelis carduelis) as my bird of the month (right), not just because it’s such a beautiful bird to photograph and draw but also it exemplifies the value of gardening for wildlife. We do not dead-head our wildflowers and other plants at the end of the flowering season but let them form seedheads. As a consequence, we get regular visits from feeding goldfinch over winter and early spring.

I have now added Sparrowhawk, Marsh Tit and Siskin to my garden survey, recorded Mallard on the riparian walk and Tawny Owl in the woodland. So far I have recorded a total of 47 native species and 5 naturalised species of bird across the four transect walks.

My bird of the week is the Tawny Owl (Strix aluco), an owl that favours woodland and wooded areas with tall hedges and trees, such as the spinney near the barns and Betchworth church where I heard it hooting this week. This medium-sized owl is primarily nocturnal feeding on voles, mice, rats, small birds, frogs, beetles and earthworms but can sometimes be seen roosting in the mature oak tree near my garden during daylight hours. I have been drawing this impressive and beautiful bird since I was a young child and it has always been one of my favourite species.

]]><![CDATA[Mad March Paul Ritchie]]>Sun, 29 Mar 2026 00:00:00 GMThttps://www.biodiversitypark.uk/blog/mad-march

Since starting the survey on first day of March I have been able to add Mallard, Sparrowhawk, Kestrel (my bird of the week), Stock Dove, Tawny Owl, Garden Warbler, Marsh Tit and Siskin to my list of sightings and hearings. I was recording a total of 46 native species and 5 naturalised species of bird across the four transect walks but the cold spell at the end of the month meant that records were down 46% on previous weeks. The sheltered conditions in our wildlife garden and the mature scrub and woodland of the riparian walk helped keep the sightings up for those two semi-natural habitats. Left a kestrel on the look out for its next meal

]]><![CDATA[Habitats for singing Paul Ritchie]]>Sun, 22 Mar 2026 00:00:00 GMThttps://www.biodiversitypark.uk/blog/habitats-for-singing

Since the arrival of spring, both in terms of calendar March and physically warmer days, the bird song in our wildlife garden has risen to a crescendo morning and evening as resident and visiting species establish new territories, select breeding pairs and build nest sites. Last week I was able to add Stock Dove and Garden Warbler to the survey and this week I recorded Sparrowhawk, Marsh Tit and Siskin for the first time. I am now recording a total of 50 species across the four transect walks.

The most sightings of songbirds occur in our wildlife garden (30%) and the riverine habitat (30%), which is a consequence of mature and extensive hedgerows and scrub habitat that provides food, shelter and secure nest sites. The farmland and woodland walks register slightly lower sightings (20%) but both support larger species of birds such as birds of prey, owls, woodpeckers and wetland species. There are some species that are seen frequently across all four walks, including Wood Pigeon, Wren, Robin, Blackbird, Chiffchaff, Great Tit, Blue Tit, Jackdaw, Carrion Crow, House Sparrow and Ring-necked Parakeet.

My bird of the week is Redpoll (Carduelis flammea), a finch that favours treetops where it feeds on the seeds of birch and alder. Our house backs onto the River Mole valley and the riverine survey walk and it is characterised by mature willow and alder woodland and riparian thorny scrub. Redpoll often feed in flocks alongside Linnet (open farmland species) and Siskin (riparian woodland species), both of which are recorded in my surveys. We have been lucky to see and hear all three species on the trees in our wildlife garden as they move through the local area feeding.

]]><![CDATA[BIRD SURVEYS 2026 Paul Ritchie, Sorbus Learning]]>Sun, 15 Mar 2026 00:00:00 GMThttps://www.biodiversitypark.uk/blog/bird-surveys-2026-paul-ritchie-sorbus-learning

My interest in bird watching started as a young child staying with grandparents every summer. During breaks from picking fruit and vegetables with my grandad I would spend happy hours with my nanny on the wild open heath at the end of their road Corfe Mullen, Dorset. She shared the delights of tiger beetles, bumblebees, sand lizard, smooth snake and Dartford Warbler. So began a lifelong journey as a biologist and wildlife illustrator.

In later years, as a countryside ranger, I used wildlife surveys to help me monitor the impact of our ecology and conservation work improving the habitats on our nature reserves. I was actively involved in butterfly transects and the Common Birds Census (CBC), a pioneering UK scheme coordinated by the British Trust for Ornithology, using volunteer-based territory mapping to monitor breeding bird populations, particularly on farmland and nature reserves.

After retirement, during the dark days of Covid 19, I found distraction and solace surveying the wild plants and animals found in our garden, which we have managed as a haven for wildlife since 2010. This was an opportunity to renew my interest in bird watching and started to record annually wild birds that I saw in and around our garden. This year a friend introduced me to the Merlin Bird ID app that I downloaded onto my smartphone and this simple tool has enhanced my ability to record local bird populations.

New project
In February 2026, I decided to start surveying local bird populations in a more consistent way. I wanted an approach that was sustainable in the context of my other commitments. A daily dog walk takes me through two different but linked habitats, farmland along the Greensand Way from our garden to the graveyard at Betchworth and small spinney next to the barns. Regular trips from our house to the Spar and Reading Room Café on Brockham Green offered a third, riparian habitat to include in surveys.

During these daily walking surveys, my visual observations are enhanced by using the Merlin app created by Cornell University, to record birds by songs and calls. This information complements daily sitting surveys in our garden, primarily at dawn and dusk. All in all this amounts to a substantial data base.

I collate the bird sightings on a spreadsheet recording presence or absence for each week. My intention is to continue this survey for a complete annual cycle.

A few weeks after I began my survey I am discovering interesting data about local bird populations I attach my survey so far. I am slowly learning bird songs and calls and I find the activity very relaxing as well as intellectually stimulating.

Over the coming year I will be sharing some of my survey results through a 'bird of the week' post.
