Rue-leaved Saxifrage, new site record for a scarce London plant in Crayford, and Musk Stork`s-bill, possibly new to the Borough of Bexley

A small colony of Rue-leaved Saxifrage (Saxifraga tridactylites),  a small spring-flowering annual, was found by me in Crayford town centre on March 12th, growing between clumps of moss on a pad of concrete, and in bare ground in short grass, inside the curve of the utility company fenceline at the junction of Station Road and Crayford Road.  There are only a handful of previous records from in and around the Borough of Bexley. I am told that the Lesnes Abbey population survives or was at least still extant in 2011. One on the North Cray Road was extirpated. I had a failed attempt to re-find it at Hall Place on March 14th, and St. Mary’s churchyard Old Bexley and Bexley station need to be re-checked. I have also had a look in Christchurch cemetery, Bexleyheath, just in case – but to no avail.

Rodney Burton, author of the last London Flora, produced in 1983, which said the plant had undergone a serious decline in the capital, is now of the view that it has since had a bit of a revival, mostly on railway tracks. He says that he has looked for it in St. Mary’s churchyard and Hall Place many times over a long period without re-finding it there. Since 2011 there have been records from single sites in Greenwich and Bromley. Further out, he has seen it recently in streets in Swanley and Greenhithe. It does seem to be associated with the built equivalent of rocky habitat, and Rodney says “It seems to me that the seeds get carried so far by the wind, and then hit a wall and drop”.

On March 14th I found an Erigeron, which appears to be E. glaucus, a  native of California and Oregon, by the A2 crash barrier between Penn Lane and Bexleyheath Golf Course. I have seen this plant in a number of Bexley gardens, but this is the first occasion I have seen it ‘in the wild’ in our Borough or anywhere else, though the Botanical Society of the British Isles distribution map shows it is a fairly frequent escapee, particularly in the London area.

On March 17th I recorded Barren Strawberry in flower in Danson Park, the first time I’ve seen it here. It’s supposed to be common in and near woodland, and is most frequent on the northern and southern flanks of the capital. But in Bexley the only other places I have found it to date are in a couple of cemeteries and at Martens Grove, where a nice patch was in flower later in the day and, from memory, Lesnes Abbey Woods.  More determined searching will probably reveal more locations for it in the Borough.

Also on the 17th I came across what may well be an entirely new record for Bexley in the shape of Musk Stork`s-bill (Erodium moschatum), a species I was aware of but had never seen anywhere before, with several specimens growing – and already in flower – in grass at the junction of Park View Road and Denham Close, Welling. This is a far larger and more robust relative of the small Erodium cicutarium, which is found chiefly in closely mown or trampled turf in sandy parts of the Borough.  E. moschatum is in some quarters classed as an achaeophyte, which is a non-native plant first introduced prior to 1492, when Christopher Columbus arrived in the New World. It has a Mediterranean-Atlantic distribution, but is widely naturalised outside this range. In Britain it is well-established in the coastal regions of S.W. England, Wales and Ireland, where it is often considered a native. Elsewhere it is encountered as an uncommon casual.

The London biodiversity records centre (GiGL) has no records of it for Bexley and Rodney Burton agrees it is probably new, saying of Musk Stork`s-bill “I saw it in Lewisham on Sunday (13th) and there are a couple of recent records from Bromley and a few further out in Kent as well”. There is also a record from Stonehill Green by Dartford Heath.

Cory ‘Environmental’ doesn’t believe its own propaganda

Cory ‘Environmental’, the company that has submitted to Bexley Council – in the name of its Belvedere incinerator arm – a plan for two four-storey buildings to cover most of the former Borax fields next to Crossness Nature Reserve, has not even bothered to check for the presence of scarce Great Crested Newts and Water Shrews, which its own long-standing signboards claim may colonise the area.

‘BW’ has previously drawn attention to the woeful inadequacy of the ‘ecological survey’ of the fields as a whole, which was funded by the company as part of the formal planning application. In addition to the above-mentioned ‘flaw’, it was only done on one day in each of September and October, and failed to mention that the fields are a breeding site for two species of red-listed birds and another that breeds nowhere else in Bexley, despite this information being in the public domain.

Now the reality is that the Great Crested Newt, which has some degree of legal protection, is something of a poster species for conservation, in that a lot of the public have heard about issues around destruction of its habitat for ‘development’,  but it is only recorded from the south of the Borough, way down beyond the Sidcup railway line, and would have huge trouble finding a safe point at which to get across the A2. The Water Shrew is very rare in London and is going to suffer similarly from fragmented habitat. Indeed according to the London biodiversity records centre (GiGL) there are no records from Bexley, with the nearest  having been made 11 years ago at Ruxley Gravel Pits. The chances of either species turning up in the ditch and pool created next to the incinerator – in order to try and give it some ‘green’ credentials – are therefore slim to non-existent, as anyone bothered to study the Borough’s wildlife would quickly conclude.

Great Crested Newts, Water Shrews? We think not. Overblown claims do not enhance credibility. And nor, now, do statements about the importance of mosaic habitat when your own survey admits a large area of it will be completely destroyed if your  planning application for the nearby Borax fields is approved .....

And nor, now, do statements about the importance of mosaic habitat when your own survey admits a large area of it will be completely destroyed if your planning application for the nearby Borax fields is approved ….. (Photo: Chris Rose)

But if you’re going to make extravagant public claims of this sort you should still make the effort to check to at least try and appear to be consistent and honest. There are established survey methods for GCN, including bottle trapping, night-time torching and now even DNA analysis of pond water. None of these were done. Surveying for presence of Water Shrews can involve live trapping, analysing droppings from tubes baited with food, and by using tubes that ‘capture’ hair samples. None of this was done either.

The boards also imply that Common Lizards will be present around the incinerator. Grass Snake is already known to inhabit the adjacent Crossness Nature Reserve. No tins, felts or other credible reptile survey work was done to check for Common Lizard or Slow Worm, despite these species being legally protected from deliberate killing or injury, which ‘development’ operations would be taken to have inflicted if no prior survey, capture and removal had been done.  A single Grass Snake was seen in the affected area, but only through a casual and rather fortuitous observation.

Moreover despite the report stating that

‘The flower rich habitats [of the fields] have the potential to support range of invertebrate species that would be more conspicuous during the spring and summer months. The possibility that the site supports an invertebrate assemblage of conservation significance exists given the flower rich and bare ground habitats present, and the sites location.’

the survey was wholly inadequate to determine whether  the nationally extremely rare Shrill Carder Bee, known to be present on Crossness NR, uses the fields, as seems quite likely.

Readers may wish to decide for themselves whether what’s on these ‘information’ boards is cynical propaganda or just down to plain stupidity, and whether the lamentable inadequacies of the ecological survey are down to arrogance (the company assuming Bexley Council will just wave the application through anyway?)  or incompetence.

Woodlands Farm starts Bee count programme

Woodlands Farm, straddling the Bexley / Greenwich border on Shooters Hill, has signed up to take part in the Bumblebee Conservation Trust bee walk project this year.  This will involve doing a walk round the farm once a month on a set route and recording any bumblebees seen.  This is every month from March to October, so should everyone involved busy!  The first one will be on Monday at 2pm. , meeting in the Farmyard, and will be used to both map the route for the rest of the year and record any sightings, though not much may be seen if it’s  chilly, but hopefully it will be a nice walk anyway.

Marsh Harrier seen over Thames Road Wetland as Peregrine perches on nearby pylon

The Marsh Harrier, once extremely rare in the UK, has made something of a comeback. Following a report of a female in the area on March 10th by Ian Stewart, I also saw a female fly low over the site at just gone 5p.m. on the 12th, heading out onto the marshes. At the same time there was a Peregrine Falcon on the pylon to the south on Stanham Farm, to which my attention had been drawn by repeated mewing calls. Having been perched there for at least 40 minutes, this bird flew off towards Crayford town centre just after the Harrier had gone past.

Earlier there had been 11 teal on a flooded field by Maiden Lane, at a distance from which they would normally have taken flight. But they seemed to understand there was a protective fence between us, so stayed put. There were 11, possibly 14 Teal on the lake at Thames Road Wetland, probably a different set of birds. A Cetti’s Warbler called as usual, and at dusk there were 2, perhaps 3, Song Thrushes singing.

On the 10th Ian had seen the Siberian race of Chiffchaff at the wetland again, plus 5 Common Chiffchaff, and also a Reed Bunting.

Brimstone seen as Braeburn bids to launch butterfly transect counts

Leslie Williams, of the London Natural History Society, who is leading the group’s project to update the mapping of butterflies in London during 2016, came over to Crayford on 12th March to meet London Wildlife Trust’s Braeburn Park Manager, Shaun Marriott, in order to discuss the best options for setting up butterfly counts at the site.

Transect counts involve walking a set route several times during the year in weather suitable for butterfly flight, and making a count of the numbers of individuals of each species seen within 5 metres of each side of the path taken. This will build a picture of numbers at the site and, when aggregated with other such data from sites elsewhere in London, a picture of trends across the capital can be derived. Obviously the more transects are monitored, the more accurate a reflection of what is really going on can be achieved from which to determine appropriate conservation actions.

As if to give an early thumbs-up to the plan, we were treated to the sight of a Brimstone butterfly in flight.

Anyone interested in helping with this valuable project should contact Shaun Marriott <smarriott@wildlondon.org.uk>  You don’t need to be a butterfly expert to get involved, and species identification help will be provided.  Some flexibility in terms of being able to go out and do a count during a break in otherwise unsuitable weather would be an advantage, but if there are enough volunteers, then between them enough counts should get done.

‘Bexley Wildlife’ welcomes 500th Facebook page ‘like’

‘Bexley Wildlife’ website’s sister Facebook page took two years to reach 400 ‘likes’, but in the last two months has accrued another 100 followers to reach a total of 501.

Jonathan Rooks, co-founder of the ‘Bexley Wildlife’ web platforms said “We’re really pleased at the way these sites are developing and helping to get more people involved.  A key aim of the sites is to use information to increase the level of interest and expertise in nature in the Borough of Bexley, and people’s enjoyment of it, in turn encouraging more people to get active in hands-on local wildlife conservation work. On the basis that information can also be power, we have also been working to mobilise people in support of campaigns for protecting and enhancing wildlife and open spaces in Bexley, and against the increasing number of threats that seek to diminish and impoverish these things that we value so much.”

Jonathan Rooks runs the 'Greener Bexley' charity.

He added “We would like to thank all those who have contributed to the content and success of our sites so far. We welcome new written and photographic material for publication. Anyone can post to the Facebook page, or post comments on the website, and we have been gradually growing the ‘BW’ team by granting full posting rights to a number of people willing and able to make a greater contribution.”

382 ‘likes’ to date are from people in London, with most appearing to be from in or near Bexley, whilst additional followers have been more specific about their locations, citing Bexleyheath, Sidcup, Dartford and Gravesend. We also have a few followers from further afield, including the USA, Australia, the Phillipines, Spain and Russia.

At present women outnumber men by almost 2 to 1. Half of all ‘likes’ are from the 35-54 age group, whilst the numbers under 25 and those over 55 are evenly balanced.

How long will it take to get to 1,000 ?????

Circling Buzzard is highlight of Thames Road Wetland visit

A Buzzard seen very high over Stanham Farm as I walked along RiverCray By-way 105 towards Thames Road Wetland, was the avian highlight of a visit to the site yesterday afternoon (March 3rd). After slowly circling for a while, and apparently moving towards the wetland, it then drifted off in the other direction towards Crayford town centre and into the sun. Perhaps it’s the bird seen at Hall Place recently.

I was also delighted to see 3, perhaps 4 or even 5 Snipe burst out of the area of cut Reed at the wetland. They hadn’t moved when I’d walked by earlier, so I was somewhat taken by surprise when I flushed them on wading out to do some more cutting and consequently failed to get a precise count as they quickly disappeared over the ‘horizon’ of tall plant stems.

Water Rails called in agitated fashion from either side of the west pool, before more squealing was heard from a bit further north. This confirms there are definitely at least two birds present still, maybe a third.

Once again a Chiffchaff was forging amongst the dry Reedmace stems, which a pair of Blue Tits were also chipping away at looking for grubs.

Chaffinches have been in short supply here this winter, and only a single female was seen.

A Grey Heron had flown over on my arrival at the site, and a Little Egret flew over towards dusk, heading south west alongside the modest stream of commuting Carrion Crows on their way to roost.

Two baby and one adult Lizards were out basking on old car tyres.

GLA election an opportunity to press case for parks and open spaces

The London Parks and Green Spaces Forum, in conjunction with the London Green Spaces Friends Groups Network, is calling on Friends groups and the wider public to use the upcoming London elections to speak out for London’s parks and green spaces.

Elections for Mayor of London and London Assembly Members will be held on May 5th. In a statement, they say ‘We urge you to take this opportunity to contact (by letter or e-mail) your local candidates and parties standing for election, to lobby for issues that are important to you in relation to London’s parks and green spaces.

Please remind them that parks and green spaces are an essential resource for all our communities, providing numerous benefits and services: health, sports, leisure, education, play, social cohesion, local economy and biodiversity, to name just a few. They are used by virtually everyone and as such they should receive the resources they need to ensure they can fulfil their vital functions. Please ask candidates to support the recommendations of the London Green Infrastructure Task Force report (see: https://www.london.gov.uk/what-we-do/environment/environment-publications/green-infrastructure-task-force-report ), in particular to appoint a Green Infrastructure Commissioner.

The heavily mown 'amenity grassland' of the former Pitch and Putt course by Bursted Wood, Barnehurst, quite unnecessarily leaves far too little for our declining Bees to feed on

Bursted Woods Open Space, Barnehurst

All the key Mayoral candidates have expressed support for London being declared a National Park City. Now they and their parties must commit to real action to protect greenspace.

In spite of the essential role London’s parks and green spaces play we are entering a local and national greenspace crisis, due to continued cuts to parks budgets, mainly a result of central government cuts to Local Authorities’ overall budgets. London Councils warned last year that cuts to local government funding mean money for parks simply isn’t there [1] Park lovers need to speak out now.[2] Past experience of revenue cuts has shown that if local spaces are poorly resourced they are very likely to become problem spaces with negative effects on our communities.

Furthermore, with London’s population rising, we need more green space. Instead, on top of cuts there is a growing pressure on greenspace in every Borough, which is leading more and more to inappropriate urban development, commercialism and even sell-offs of green space.

Your local parks/green spaces have their own specific issues and needs which ought to be heard and addressed.  With nearly 600 local Friends Groups in London, this is a growing and powerful grassroots force – we encourage London’s residents to publicly raise the profile of local parks and the benefits that they afford local communities.  Your group can influence future Assembly Members and political parties who will make funding and other decisions that will impact on your local park. Please consider writing to all kinds of networks and your local newspaper too. This is your opportunity to make our local parks a priority.

Thank you for your support.

Yours sincerely, Tony Leach, CE, London Parks & Green Spaces Forum. c/o 18 City Hall, The Queen’s Walk, London, SE1 2AA

_________________________________

Facts & figures

Research in 2010 showed: 87% of people have used their park or green space in the past year, more than any other public service, and 95% of people thought it was very or fairly important to have green spaces near to where they live. If people are satisfied with their local park they tend to be satisfied with their council.[3]

  • Obesity and inactivity are impairing & shortening the lives of millions of people in Britain. Almost 25% of British adults are clinically obese with a further 40%[4] overweight and in danger of becoming obese. 18.9% of 10-11 year olds are obese[5] – if not tackled this will be a drain on the NHS for years to come.
  • Obese and overweight patients cost the NHS £4.2bn per year with a further £11.6bn lost to the economy[6] through lost work days etc. A major cause of obesity, and other health problems, is inactivity – 23% of adults are classified as inactive, reducing this to 22% would save the NHS an estimated £1.44bn[7]. A brisk walk every day, in a local park, can reduce the risk of heart attacks by 50%, strokes by 50%, diabetes by 50%, fracture of the femur by 30%, colon cancer by 30%, breast cancer by 30% and Alzheimer’s by 25%[8].
  • Almost 25% of Britons are classified as obese – compared with a European average of 16.7%.[9]
  • Type 2 diabetes accounted for less than 3% of all diabetes cases in adolescents in 1990, but that share had risen to 45% in 2005[10].
  • Physical inactivity affects 60–70% of the adult population and increases the risk of obesity, type II diabetes, cardiovascular disease, cancer, hypertension and overall bad health[11].
  • MIND recommends that green exercise be seen as a clinically valid treatment for mental distress[12]. The treatment of mental illness in England requires annual NHS expenditure of £3.8 billion[13].
  • Simply being outside in a green space can promote mental well-being, relieve stress, overcome isolation, improve social cohesion and alleviate physical problems[14].
  • Unlike antidepressant drugs that cost £750 million a year, green exercise is free and does not carry the potential for negative side effects[15].
