Shocking treatment of Lower Ashley Road trees shows urgent need for Bristol Planning rethink

Bristol has declared a climate emergency. There is an urgent need for all council departments to re-think the way that they work.

At the time of writing, four of the trees in this image have been felled (two Norway Naples and two Indian Bean trees on a different plot).  The value of the five maple trees along Lower Ashley Road was calculated at £200,000 using CAVAT.  Local residents are desperately trying to save the three remaining maples.

This blog discusses six changes that are desperately needed to protect trees on development sites.

  • Planning Decisions regarding important or TPO trees should be considered by committee and not delegated to one officer.
  • It is practically impossible for local residents and other stakeholders to wade through all planning documents online. Planning Officers must highlight important tree issues and have a duty of care to act positively in favour of trees.
  • Bristol should implement policies to retain trees on development sites in the way that has been done in London, Oxford and elsewhere. This includes enforcement and a presumption to retain trees at the edge of development sites.
  • An emergency number to address immediate tree felling issues. 
  • It is a false choice to say that we can either have social housing or trees. With clever designs, we can retain existing trees and have better social housing.
  • Replacing felled trees, even when applying the Bristol Tree Replacement Standard, is second best to retaining existing large urban trees. We get the benefits from existing trees now – we have to wait decades for their replacements to grow.

Over the last six months there have been half a dozen articles in the local press and now one Guardian article about the shocking planning decision to allow removal of five Norway maple trees with Tree Preservation Orders (TPOs) on Lower Ashley Road, one of the most polluted streets in Bristol. There have been two meetings with the mayor who also visited the site and there is now a vigil by protesters on the site: police have been called on several occasions. All this indicates a planning process that has marginalised local residents and failed to take into account the value of the trees.

The Bristol Tree Forum appreciates the efforts by Mayor Marvin Rees to try and resolve the situation after the event. He visited the site and then convened two meetings in City Hall which he chaired. We have been impressed by his serious engagement and the way that he has brought all the interested parties into the room and handled the discussion. But, as we think he would agree, this is the wrong way around. Discussions such as this should happen before the planning decisions are taken so that there is community engagement in the decision making.

Planning Decisions regarding important or TPO trees should be considered by committee and not delegated to one officer

That we have got to this stage shows a serious failure of both Bristol City Council Planning policy and its implementation. The decision to remove the trees was taken in 2015/16 by one planning officer as a reserved decision. It did not go for to the Planning Development committee for a considered decision. Looking over the documents it doesn’t seem that any time or thought was given to the trees. The Arboricultural Report provided by the developer does not even state whether the trees had TPOs, and indeed there is no discussion of the TPOs in any of the documents in that planning application, with the only mention on the “constraints” page. In 2015, The Bristol Tree Forum commented in opposition to the proposal but even the BTF was unaware that the trees had TPOs. Whilst BCC insists that the decision was “valid”, without a mention of the TPOs there was insufficient information to allow intelligent consideration of the proposal, so we question that decision. Sufficient information for intelligent consideration is one of the fundamental principles of a “proper consultation” as decided by Lord Woolf*. The first mention of the TPOs in a document is in the Officer’s Report outlining the delegated decision. 

Unfortunately this is not an isolated failure: trees all over Bristol are being unnecessarily sacrificed as a result of applying ideology from the 1960s. For example a single planning officer gave the green light for the removal of some 25 trees on the Redland Girls School site, in a conservation area, despite the fact that the removal is purely for landscaping.

Redland Green Trees: damage to tree roots caused by driving construction vehicles over them can result in the eventual failure of the trees. In a failure of planning, no root protection zones or Arboricultural Methods Statements were ever established for these trees, despite permission being given for the construction company to store materials on Redland Green.
It is practically impossible for local residents and other stakeholders to wade through all planning documents on line.  Planning Officers must highlight important tree issues and have a duty of care to act positively in favour of trees

Important tree issues need to be highlighted and openly discussed during the planning process. Planning Officers already implement policy regarding flood risk, traffic management and other construction matters. The Bristol Tree Forum is asking that tree protection is included too as is done in other local authorities (Examples are Oxford and Islington, below). In addition, trees on or near active development sites must be properly protected.

We see applications with no information on the Bristol Tree Replacement Standard calculations, or obviously incorrect information being supplied. Documents such as these should be rejected by the planning officer.

Redland Green Trees. Permission was given for this TPO Ash tree on Redland Hill to be removed (in addition to several others on the site) to allow articulated lorries to enter the building site. In the event, the gateposts were never widened, articulated lorries didn’t enter the site as this would have been extremely difficult even with gate widening and the tree was retained until Aug 2019, when it was removed anyway.

All that remains of the Indian Bean trees which were chainsawed following rejection of an application that was refused because the trees were felt important and merited TPOs.  The trees were removed anyway. We are trying to find out why the trees were not then protected with TPOs.
An emergency 24-hour number to address immediate tree felling issues. 

Bristol is at risk of becoming known as a Mad Max world now that unqualified people are wielding chainsaws from ladders above passing pedestrians with no enforcement consequences, often on public holidays, sometimes in the evenings and even at night. A proper approach for addressing this problem needs to be developed in collaboration with the police. It is unfair to send a single tree officer on their own to deal with issues of public order. Multiple phone calls and sometimes hundreds of emails to numerous council departments very quickly overload already overstretched council officers. It is no good passing the buck to the Health and Safety Executive. Therefore we need one emergency Bristol City Council number.

Lower Ashley Road.  Bristol City Council urgently needs to come up with a procedure to address dangerous activities by unqualified people using chainsaws over pavements and roads.

Bristol should implement policies to retain trees on development sites

Where possible we should build developments around existing trees. There should be a presumption to build around existing trees and particularly to retain trees at the edge of development sites. 

The developer’s arboricultural report for Lower Ashley Road states that “In order to retain the trees within any new scheme, the front of any new building will need to be sited a minimum of ten metres from the existing site boundary”. We have heard this assertion stated by developer and planner as “the ten metre rule”.

There are many examples where mature trees are retained close to new buildings, in London, Oxford and elsewhere. This must become commonplace in Bristol too.  A Trees and Design Action Group article describes the construction of the Angel Building (Islington, London) around existing mature trees. No cowboy chainsawing there. Instead extreme care was taken in a project that was led by landscape architects. For example:

Deliveries needed to be conducted on a daily basis. To enable this, the Tree Protection Plan (TPP) and Arboricultural Method Statement (AMS), developed by appointed tree specialist JCA, in coordination with the project landscape architect and the council tree officer, proposed the use of a porous load-spreading cellular confinement system (Geoweb) braced with timber frames.

All existing trees were irrigated during the two-year construction period following a sporadic pattern imitating rain. Because irrigation was fed with calcium-rich London tap water, the system was fitted with filters to avoid increasing the soil pH.

Aurora Building, Counterslip, Bristol.  Energy efficient, outstanding architecture and built extremely close to an existing plane tree.
It is a false choice to say that we can either have social housing or trees. 

Although the 2015/16 planning approval that is being used to justify removal of the trees was for student accommodation, the current proposal, still under consideration, is for social housing that Bristol desperately needs.  We are surprised that, despite this new undecided application, the developer is still able to undertake work under the old approved application which they no longer intend to pursue.  Shouldn’t the slate be wiped clean so we have a chance to revisit the whole plan with the trees still in place rather than be forced to decide without them?

The developer, planners and others have presented a false choice stating either we retain the trees, keep the site derelict and leave 28 families homeless, or we remove the trees. 

These trees are right on the edge of the development site. With clever designs, led by a landscape architect (not even apparent that one has been engaged for this project), and carefully constructed foundations (e.g. screw piling), the developer could build close to the existing trees. The result? Better social housing which benefits from existing green infrastructure and provides a more pleasant environment with some protection from the noise and pollution of this busy road.

Council no longer manages trees on educational sites

There are some 166 educational sites and 63 playing fields across the city. Together they cover over 560 hectares and form a significant proportion and an important part of the city’s open, green spaces.

Despite this, Bristol City Council no longer manages trees growing on many of these sites and their related playing fields. We are not certain, but we imagine that this situation has come about as a result of the decline in local authority control over state educational provision with the rise of independent Academies.

We issued a Freedom of Information request (FoI) to try to find out which sites remain under the control of the Council, but our request has been refused on the grounds that answering it would impose a significant burden on the council. Our more generic request at the end has also been refused on the same grounds.

The trees at Stoke Lodge Playing Fields

Recent events at Stoke Lodge and the playing fields there perhaps best illustrate our concerns and the potential threats to the many trees growing on land set aside for educational purposes.

The site was leased for 125 years to Cotham School in August 2011. Interestingly, the Council agreed to retain its responsibility for all the trees growing on the site. It also agreed to indemnify the school for any damage the school might cause to the trees and to insure against this risk.

Stoke Lodge Playing Fields are located to the west of the city in Stoke Bishop ward and cover some 8.7 hectares of open space. Historically they were part of the grade II listed lodge (now an adult learning centre) of the same name which covers about two more hectares and contains an arboretum of important trees (the survivors of a collection that formerly spread right across the historic lodge grounds).

Unlike most of the land around it, this part of Stoke Bishop is not in a Conservation Area. For some 70 years, the whole estate, which until recently had never been seen as a divided space, has been used by the local community and is designated an important open space. Nearly all the trees on the Stoke Lodge estate are subject to Tree Preservation Orders (TPO) which were placed on the trees in early 2012.

The TPO trees and canopies

In the summer of 2018 Cotham School announced that it intended to erect a fence along the boundary of its leased land. They stated that they did not require prior planning permission to do so because they were exercising their statutory Permitted Development rights. After an initial dispute about whether the school could indeed use Permitted Development rights, in January 2019 work began to erect the fence.

It was at this point that the Bristol Tree Forum became involved after it became clear that the proposed route of the fence would pass through the root zones of a large number of important trees, many of which were the subject of a TPO.

The original plan – the fence passing through the root zones of many protected trees.

There then followed a protracted period of back and forth representations while we and the local community fought to get the fence relocated to avoid damaging the trees. This was partly successful. Where it was not, we were able to insist that the methodology for erecting the fence where it still passed through tree roots was modified to minimise damage. Even so, it took the constant vigilance of the local community and BTF representatives to ensure that Cotham School did not ignore the conditions placed upon it.

Setting aside the issue of the siting of the fence, our primary argument has always been that TPO law requires a prior planning application to be made (and approved) before any work is undertaken that could cause damage to TPO trees. Initially, the Council rejected this argument, effectively stating the Permitted Development rights trump primary TPO legislation. It also argued that, anyway, it could not proactively prevent damage to TPO trees, but had to wait until the damage has been done, which is, frankly, absurd. We continued to challenge these interpretations and, eventually, the Council conceded our points, though only after the fencing had been completed.

Things then appeared to return to normal,except that the community was now largely confined the unfenced areas around the boundaries of the site. As a result, the trees around the boundary are being exposed to heavier traffic through their root zones. We are concerned that this may have a long-term, adverse impact on their health.

Then, in August of this year, and without any warning, contractors arrived to lay cable ducting across the site so that video surveillance equipment could be installed. Using a mini digger they immediately set about driving over and cutting through the root zone of a TPO Common Ash growing on the boundary of the site. Other non-TPO trees (some privately owned) were similarly damaged.

Digger in amongst the TPO Ash roots

It soon became clear that the contractors had neither been advised of the TPO status of the tree nor of the proper methods to use when working within tree root zones as set out in BS 5837 (Trees in relation to design, demolition and construction – Recommendations), or in the NJUG Guidelines for the Planning, Installation and Maintenance of Utility Apparatus in Proximity to Trees. This was despite the Council being aware of, and engaged with the school’s plans.

We lodged a complaint with the Council’s Planning department. As a result, enforcement proceedings were commenced and the school, whilst narrowly avoiding prosecution, was obliged to take remedial action to try to mitigate the damage caused to the tree. The council also felt obliged to remind the school of its obligations to TPO trees:

And this is a site where the trees are still under the ‘guardianship’ of the Council! What about those sites where the care is vested with the school?

Our concerns remain for the future health of those trees whose root areas had been invaded by the fence installation. We have also continued to express fears about other continuing threats to the trees arising as a result of other activities on the site. So far, our concerns have been ignored.

For example, continuing root compaction and branch damage is being caused to the Persian walnut growing by the gate close to the rear car park and to the trees growing beside the Parrys Lane entrance. This is the result of grass mowers and other service vehicles using these entrances to gain access to the site. We are told the access point has been moved to the Parrys Lane entrance, though that too involves vehicles passing over tree roots.

Driving over the walnut’s roots on the way to mow the playing fields

Historically, it looks like vehicles accessed the site from behind the Children’s Play Ground on the southwest of the site, so did not need to drive over any tree roots. The presence of the fence and lack of any gate there has now closed off that option.

The school’s contractors also continue to mow within the root zones of the two large Turkey oaks (BCC-77025 on the eastern end & BCC-77059 on the western end) that grow inside the playing fields fence.

The eastern Turkey oak

However, the Council and the school decline to address these issues saying that they have made adequate arrangements to safeguard the trees.

STOP PRESS – 4th January 2020 – since writing this blog, Cotham School has felled a TPO protected Elder (plus five others) on the Eastern side of the playing fields and poisoned it with Glyphosate. We have informed Bristol Council Parks and Planning Departments and asked them to investigate. They advise:

“The felled Elder trees were not included within or protected by the TPO covering the adjacent Sycamore tree.

It is very unlikely that roots from the Elder trees will have grafted with the roots from the Sycamore tree. Also translocation of herbicide between grafted roots is very unlikely.

We are not aware of any plans to fell the twin stemmed Oak beside the white shed at the eastern end of Stoke Lodge Playing fields.”

But, when we asked Parks if these works were done with their prior knowledge and agreement, or if the department had approved the application of Glyphosate to the tree roots, or if they had seen the School’s Aboricultural Management Scheme, they answered ‘No’.

It seems that the school had complied with their obligation to get consent from the Council, their Landlord, but that the Council’s Education Asset Management team had failed to consult Park’s specialist tree officers about the plans.

More details can be found here.

The aftermath

Cotham School has issued these FAQs – 33 to 38 in response to this issue.

The fate of other educational sites

In the meantime, we have no idea if or how other schools are managing the trees on their sites, or if the Council is consulted when they do.

Even though, in most cases, educational sites are still on Council-owned land, the Council only needs to be told if the trees have a TPO or are growing in one of the city’s 33 conservation zones (or, we assume, if the Council’s lease with the school keeps the management of the trees in the control of the Council – as was the case at Stoke Lodge).

Given that Bristol City Council does not normally issue TPOs for trees on its own land, arguing that it is a good landlord and will look after important trees appropriately, it is unlikely that trees that have been handed over on other educational sites will have been protected by a TPO. Perhaps the council should now review its policy where it no longer manages trees growing on educational sites in light of this history.

Certainly it seems that new tree planting need no longer involve the Council. For example we recently observed that several newly planted trees at Cotham School’s main site had died. It was only when we noted that the dead trees were missing from the Council’s tree stock data for the school that we learned that they were no longer responsible for the trees on the site. We have now been told by the school that the trees were planted as part of a recent development and that the failure of these dead trees will be ‘rectified’ soon. Meanwhile, it seems that these new trees are no longer selected, managed or mapped as part of the Council’s wider tree stock strategies and that the existing trees on the site are no longer the Council’s concern.

Presumably, similar arrangements are happening across the city with other educational sites being left to make their own, ad hoc arrangements to plant trees or not. Given that the One City Plan aims to double tree canopy cover over the next 25 years, it seems a great shame that this important land bank of possible new planting sites might have been excluded from helping to achieve Bristol’s plans.

We are also concerned that school governors (quite apart from lacking the necessary skills to manage the trees growing on their sites) may not yet have realised the full implications of the practical and strategic obligations that taking on such an important part of Bristol’s tree stock places upon them. As a result, they are likely to have to buy in (at our expense) ad hoc expertise, thereby possibly overlooking the wider strategic considerations that are needed when it comes to managing trees across the city.

This, coupled with the distinct possibility that well-meaning but unqualified Council officers may be making critical decisions about the welfare of trees on educational sites, makes for a very worrying situation.

Changes agreed to Bristol Tree Replacement Standard

‘Only when the last tree has died, and the last river has been poisoned and the last fish has been caught, will we realise that we cannot eat money.’ – A Cree Indian speaking in the 19th Century.

Members of the Bristol Tree Forum (BTF) recently met with senior Planning Officers and the two Arboricultural Officers working in the Department. We wanted to raise a number of planning issues that have been concerning us.

The Bristol Tree Replacement Standard (known as BTRS – you can find it at page 21 of the Council’s Planning Obligations Supplementary Planning Document) is a flagship policy copied by other planning authorities. Bristol should be proud of it. We are because it goes a long way towards making sure that trees and tree canopy lost to development is replaced at the expense of the developers.

This is how the BTRS formula is applied (the diameters shown are in centimetres):

However, in the years since its inception about ten years ago it has become apparent to us that the policy could be improved if some changes to the way it is applied were made to it. Two things that have particularly concerned us are:

Firstly, it had become apparent that developers and householders developing land in Conservation Areas were avoiding their obligation to mitigate tree loss by submitting two separate planning applications – the first for the trees to be felled (usually for some spurious reason), then, months later, a substantive application to develop the now tree-free land.

Outside Conservation Area, where there is no protection for trees (unless they have a TPO) at all, the trees were simply being felled, sometimes in large numbers, some time before an application to develop the land was submitted.

In either situation, if the development was permitted, the trees were lost, never to be replaced, because the loss was not considered to be “in association with” the development of the land.

Secondly, if developers or householders were developing land and the BTRS was being applied, we noticed that in some cases, hedging was being approved as a replacement for the lost tree canopy. Whilst grand hedging might indeed be appropriate as part of the planning proposal – say as screening or as a pollution mitigation measure – we do not believe that it can ever be used as an adequate substitute for lost tree canopy.

In particular, we noticed that this option was being proposed by those developers who had filled nearly all of the site so that there was little, or no room left for replacement tree planting on site. In our view this was being done to avoid having to pay the Council (us really) for replacement trees to be planted nearby.

We are pleased to report that, after several meetings with Officers to discuss our concerns, the following has finally been agreed:

  1. Where there is evidence of prior felling, BTRS will be applied retrospectively to include all trees felled within the year before the planning application. In this way any trees felled before the development will be taken into account when considering the application of BTRS.
  2. Other than in exceptional circumstances, hedges will no longer be acceptable as mitigation for tree canopy loss when applying BTRS.
  3. If council officers think it is necessary, these new protocols will be written into the Council’s Planning Practice Note so that there is no possibility of any future misunderstandings by either developers or planning officers how BTRS is the be applied.

BTF has more ideas which we believe will strengthen the application of BTRS (for instance, why should trees under 15 cm not be replaced?; should BTRS be applied in non-development tree felling applications?) . We will continue to advocate for these and other possible changes.

We accept that there is always going to be development, but we must try to ensure that the city’s tree cover is, at the very least, protected and maintained in keeping with SDG 15 – Life on Land of the One City Plan Sustainable Development Goals which commit to doubling tree canopy cover by 2046.

Redland Hill street trees felled by the Council. Why?

Until a few weeks ago there was a lovely informal stand of trees along Redland Hill, which is a busy road that I walk up twice a day to get to the Downs.

As it used to look – Google Street View – July 2018

Rush hour stationary traffic belches out pollution and the trees provided some respite.  I have watched over the years as several of the old beech trees were removed.  They were probably once part of a beech hedge that predates the existing buildings (and the wall): now only one is left.  Instead, an informal collection of ash and other trees grew in their place.  This was a great place to see Broomrape, a parasitic plant that grew at the base of some trees.

How it now looks…All gone – just one lonely beech and some street furniture left to improve the view.

There was no consultation of any kind with the community. One day the trees were there, the next they were gone. Without any involvement from the Bristol Tree Forum, the local councillor or the local community, we can only guess why the trees were removed. Perhaps it was concerns about the nearby wall.  A careful examination shows that there are no obvious cracks, even close to the one remaining beech tree.  Was a proper engineer’s survey done? In days gone by a Bristol City Council Tree Officer defended a tree, similarly close to a garden wall, that the owners wanted to cut down, even obtaining an engineer’s report. Even if there were substantial damage to the wall, other options were possible, such as thinning out the trees (only some were marked with green paint) or laying them as a hedge as was recently done in Redland Green.

…just sawdust, rubbish and some ivy (now hacked down), nothing else.

Of course the removal may be for a different reason. Maybe what the developers really wanted to do was to create views for their flats and successfully put pressure on the council? Perhaps the pavement will be widened?  Or perhaps the area will be dug up for services. I don’t think the removal of trees was in the planning application.

At this time, with the threat of Ash die-back disease we should be looking to keep healthy ash trees in case by chance they turn out to be the ones that are resistant. Cutting down healthy ash trees is misguided.

The money that was spent cutting down these trees should have been used for planting new street trees, something that Bristol City Council says it has no funds to do. I’m guessing more money will now be spent to tarmac over the area where the trees once were. 

Bristol City Council should have thought differently. For example, it should have enforced a root protection area for the last remaining beech tree. This was apparently not done and I guess we will see that last tree fail in the next ten years.

At present, Bristol City Council refuses to consult over tree felling decisions, despite requests from the Bristol Tree Forum for a decade. It is almost as though the council thinks there are no inhabitants in the urban forest and that they always know best. Unilateral decisions such as this show how important the government’s proposal is to require local authorities to properly consult before removing street trees

Bristol has an ambitious plan to double its tree canopy by 2050. Yet all over Bristol, on an almost daily basis, tree canopy is being lost – for multiple reasons. Just in the local area, about half a dozen really large trees have gone and the canopy cover has decreased. We did manage to get one new street tree, in the middle of Redland roundabout but it took a four year battle and the help of our local MP to get it planted. Trees are lost very gradually in our bit of Bristol and are often not replaced.  So the change in canopy is not obvious. Fisheries biologists have coined the term “shifting baselines”, where each generation sees only minor negative changes. But the effect over a long period is substantial.

As Professor Corinne Le Quere has said, “actions to tackle climate change have to penetrate all the decisions that we take in society”. We are hoping that we can get this point across to the decision makers in Bristol City Council.

The Bristol Tree Forum will now be campaigning for these trees to be replaced.

Ancient and Veteran Trees explained

These two terms are in common use, but they have specific meanings when it comes to their conservation. All ancient trees are veterans, but a tree may qualify as a veteran without being ancient.  Most British trees increase in girth over their lifetimes by 2.5 cm a year. They grow faster when young, when in the open as opposed to woodland, and when in good soil rather than bad. They grow slower as they get older. Some species grow faster than average, such as Black Poplar, Plane, and Wellingtonia, and some more slowly, especially Limes and Hawthorns.

Trees are very good at vegetative reproduction, so that they are effectively eternal. Some create their own clumps, each tree being a clone. They do this by branches that arch down to the ground, root, and send up new vertical trees. The Tortworth Chestnut, which was regarded as ancient in King Johns reign, is a good example, but some of the limes on the Downs are doing this. Some trees send up new shoots from the base of the trunk which eventually replace the original tree. Many trees if cut to the ground, by storm or men, will promptly create new shoots, and this is the basis of coppicing which was a standard woodland management tool from at least Roman times. There is a Small-leaved Lime at Westonbirt Arboretum that now consists of a ring of clones about forty metres in diameter.

Ancient trees should be at least two hundred years old, and hence have a girth of more than five metres. I have measured 120 trees in Bristol with this girth, and there are many more in Ashton Court that I have not checked.   They matter because they provide a range of habitats to a range of species. They are always hollow, often squat,  having long since lost their upper branches, their hearts eaten out by fungi and beetles, full of nooks and crannies, and often clothed in lichens and ferns. They are most frequently Oaks, Sweet Chestnuts, Planes and Cedars.

Veteran trees are defined by their individuality. They will be mature, around 140/150 years old, about three metres in girth, mostly still standing tall. Fine, significant specimens of their species both in form and biodiversity. They are candidates to become Ancient, they may be starting to go hollow, and hence be of concern. They may need management to avoid their becoming top heavy, or developing a dangerous lean. They will stand out from other trees in their particular locality and may have planning protection as a consequence. They may also have special features of note, such as being multi-trunked.

Trees and Planning

The National Policy Planning Framework document (issued in July 2018) has the following definitions at Appendix 2: Glossary.

Ancient or veteran tree: A tree which, because of its age, size and condition, is of exceptional biodiversity, cultural or heritage value. All ancient trees are veteran trees. Not all veteran trees are old enough to be ancient, but are old relative to other trees of the same species. Very few trees of any species reach the ancient life-stage.

Ancient Woodland. An area of woodland that has been wooded continuously since at least 1600 AD. It includes ancient semi-natural woodland and plantations on ancient woodland sites.

Irreplaceable habitat: Habitats which would be technically very difficult (or take a very significant time) to restore, recreate or replace once destroyed, taking into account their
age, uniqueness, species diversity or rarity. They include…ancient woodland and ancient and veteran trees….

Paragraph 175 (at page 51) of the framework states:

When determining planning applications, local planning authorities should apply the following principles:

c) development resulting in the loss or deterioration of irreplaceable habitats (such as ancient woodland and ancient or veteran trees) should be refused, unless there are wholly exceptional reasons and a suitable compensation strategy exists;

Paragraph 2.17.6 of DM17: Development Involving Existing Green Infrastructure – part of the Bristol Local Plan echoes this:

Due to their characteristics and value, Aged and Veteran trees are considered to be of relatively greater importance than other trees and even trees of a similar species. Aged trees, by definition, have developed characteristics associated with great age and often have particular landscape and townscape value. Veteran trees are considered to have particularly important nature conservation value. Both will often have significant visual amenity, and potentially historic and cultural importance. As such their loss or harm will not be permitted, and the design and layout of development will be expected to integrate them into development.

These guidelines apply whether the tree or woodland grows in a public or a private place.
