Bexley RSPB: programme of local bird walks

The Bexley group of the Royal Society for the Protection of Birds is by far and away the largest wildlife/nature group in the Borough, so encouraging its members and other local residents to take a keener interest in the value of local sites and their protection is a key issue. To deliver on that objective, a series of bird walks to a variety of sites and habitats in Bexley has been arranged for the coming months.

RSPB Bexley Group Field Trip – Crayford Marshes Thursday 24th September 2015

Avocet the highlight as rain gives way to sun on Bexley RSPB Crayford marshes visit.

It was raining hard at 8am, raining at 9am, cloudy 10am and brilliant warm sunshine 11am – surprisingly 6 members arrived to join us for the early autumn walk around Crayford Marshes from Moat Lane to the River Thames.

We wandered past Howbury Moat and surrounding meadows also taking in the landfill site – very little bird activity apart from the constant call of ring-necked parakeets. However we soon noticed a slow but almost constant movement of swallows and house martins, a good opportunity to compare like with like on the wing. Alas, no luck with the little owl in the willows, we would try again on the return walk.

Once onto the river wall overlooking the River Darent, Crayford and Dartford marshes – a fabulous 360 degree view with more hirundines moving. The odd small birds flitted amongst the dense scrub, blackbird, dunnock, robin, blackcap, collared doves and a Cetti’s warbler calling. We arrived just as the high tide turned so little to see as we walked down river, one bush held 4 reed buntings but even they disappeared under our gaze. A kestrel hunted and a grey heron rested.

By the time we reached Crayfordness (where the Darent meets the Thames) there was enough mud exposed to show a gathering of black-headed gulls, single great and lesser black-backed gulls – close enough for good comparison. On the Dartford side there were a couple of dunlin hiding amongst around 40 redshank, 7 black-tailed godwit and a single avocet all showing in good light. Avocet is not a common visitor to the Thames this far up but the odd one is being seen fairly regularly during autumn/winter. Another species being seen more frequently and probably the highlight of the walk and not a bird were the two common seals hauled out on the tide-line. We continued our walk almost reaching Erith Yacht Club before time decreed we must return. Seal numbers had doubled by the time we reached the Ness again and we noticed that they must have been resting up against the bank as we could clearly see their trails where they had slithered their way down to the tideline.

Our return walk produced a few teal, mallard, a common sandpiper flying away and two little egrets as we searched once more in vain for the little owl.

All in all an enjoyable three hour walk if a little light on species but we were extremely grateful to remain dry throughout.

Species seen:- Cormorant, little egret, grey heron, mallard, teal, kestrel, black-headed gull, herring gull, great black-backed and lesser black-backed gull, black-tailed godwits, avocet, redshank, dunlin, common sandpiper, wood pigeon, collared dove, ring-necked parakeet, swallow, house martin, dunnock, robin, blackbird, blackcap, chiffchaff, Cetti’s warbler, blue tit, magpie, carrion crow, starling, reed bunting, house sparrow. Four Common Seals.

What do we know about the status of our wildlife? Free lecture series.

Ecology and Conservation Studies Society, Birkbeck Free Lecture series.

Autumn 2015: six Friday evenings, Oct 9th to Nov 13th, 18:30 to 20:00. Birkbeck, University of London, Lecture Theatre B36, downstairs at the Torrington Square entrance.

In Britain we have a long and proud tradition of monitoring the distribution and trend of birds, plants and butterflies, using volunteers from natural history and conservation societies. Recently, modern technology has led to a burgeoning number of these “citizen science” schemes using a wide pool of contributors, on everything from the parasites of the chestnut leaf miner to plants indicative of good habitat, from swifts to stag beetles. Schemes can collect haphazardly or according to a fixed protocol. Some schemes have been so successful that they are used as government indicators, but others may not deliver on expectations, and taxonomic coverage is patchy. In this series our lecturers look at what makes for success.

Oct 9th. The good, the bad and the ugly in UK Biodiversity monitoring. Richard Gregory, Head of Species Monitoring and Research, RSPB.

Oct 16th. Stories from London: the role of local records centres.  Maria Longley and others, Greenspace Information for Greater London.

Oct 23rd. The State of Britain’s Moths. Richard Fox, Butterfly Conservation.

Oct 30th. The Biological Records Centre: valuing wildlife observations in a changing world.  Helen Roy, Centre for Ecology and Hydrology.

Nov 6th. Citizen Science in Action at the Open Air Laboratories (OPAL).  Dr David Slawson & Dr Poppy Lakeman Fraser, Opal, Imperial College London.

Nov 13th.  Monitoring hoverflies with digital photographs.  Roger Morris, consultant.

A reading list, will be available later. To receive this, please email

ecssoc@gmail.com, consult the website

http://www.bbk.ac.uk/geds/our-research/ecss/free-public-lectures, or pick up a copy at one of the lectures.

The free public lectures are in a series hosted by GEDS, Birkbeck University of London. They are suitable for those who may be considering, or undertaking, university courses in ecology, biological conservation or related subjects. They will interest environmental and ecological practitioners, natural historians, wildlife organisations and others with similar interests.

The lectures are supported by GEDS, Birkbeck University of London and would not be possible otherwise. They are organised and promoted by the Ecology and Conservation Studies Society.

Thames21 team brave rain to clear river and plan Thames Road Wetland work

Cray River project boss Michael Heath, Chris Rose, Ray,  Ron Pearson and Wren Rose turned out for a planning meeting at Thames Road Wetland on Wednesday 16th, despite the persistent rain, but first cleared a blockage of rubbish in the River by By-way 105.

Having opted to use a grappling hook from the bank, rather than the more time-consuming alternative of rowing the boat down from the yard, it transpired that what we were dealing with was a rather heavy set of fence posts lashed together to make a raft, covered with orange mesh. This and other pieces of wood had got wedged in the river, trapping the usual assortment of beer cans and fizzy drinks bottles. Once out of the river this material had to then be carted up to Thames Road for collection by the Council. The fence posts were cut free and used to augment constructed Lizard basking sites on the wetland.

A wetland walk-around then ensued in order to plan for next week’s working visit by sixth-formers from a nearby school. Michael pointed out a blindingly obvious Marsh Sow-thistle growing by one of the inlet sluices, which I had somehow missed despite beating a path through surrounding vegetation on a number of recent occasions. The significance of the plant is that it is the first self-sown specimen of this nationally scarce plant to have got to any substantial size.

I stayed on to do some site management work,  with the rain finally petering out mid afternoon. Despite the weakness of the ensuing sun and cool air temperatures, 3 baby Lizards came out to bask on tyres, and a Small Copper butterfly was disturbed from some long grass. Shed skin from 2 different Grass Snakes that had been noticed earlier was collected to send off to a project looking at snake genetics.

A mobile Cetti’s Warbler vocalised quite often from various parts of the site, and may have been the same or a different individual to one calling from the opposite bank of the nearby Cray. Two Water Rails were heard making their pig squeal sound from within the reedswamp. Between 18.41 and 19.17 some 86 Carrion Crows flew south/south-west over the wetland.

Dr. Livingstone moment at Danson as early Shoveler plays tricks on the mind

Yesterday’s trip to Danson Park (Sept 18th) was prompted both by news of baby Newts trying to exit the Old English Garden pond (see separate post) and also Ian Stewart’s London Bird Club wiki report of a pair of Gadwall here on 15th September.

The Gadwall, a species familiar down on the Thames at Crossness, but only very occasional at Danson, were both still there. A slightly different duck was preening on a log, but I could only get a three-quarter rear view in indifferent light. The plumage was a bit odd and the bill looked Shoveler-like.  I turned away for a minute or two, and when I trained my bins back on that spot a male Mallard was there, with no sign of any possible Shoveler. I convinced myself my mind had been playing tricks and moved on, occasionally looking back down the lake but with no suspect in sight.

A Little Grebe was seen, and there were 8 Cormorants on the island trees.

A person cycling towards me on the lakeside path looked vaguely familiar, and maybe interested in what I was doing, but as I didn’t recognise them I was avoiding eye contact. ‘Chris Rose, I presume? (or words to that effect), he said. It was Ian Stewart who I’ve never met before, but who provides numerous bird and new Dragonfly site records in the Borough. He was out again trying to maintain his 50-or-more species a day ‘patch list’ record.

Dusk was coming on and large numbers of Ring-necked Parakeets were gathering in trees on the south side of the lake, in preparation for flying over to the roost Poplars. Ian wanted to get on, and as we still haven’t sorted out where all the RNP’s from the south are emanating from, I went outside the park. By now I had missed the main movement, but it seemed that stragglers were only coming in from the south and south-south-east by this time.

When I came back Ian was coming along the dam wall to complete his lap, and pointed out a Kingfisher on the frame of one of the kayak polo nets. Earlier he had drawn my attention to a Yellow-legged Gull, something currently beyond the limits of my bird ID skills. And he had seen the Shoveler, which was an eclipse male. This is unusually early for this species at Danson, as in my experience it tends to only show up – certainly in any numbers – in cold winter weather.

Newt rescue at Danson Park

Thanks to an alert from John Arnold, I was able to rescue 50 baby – almost certainly Smooth (and not Palmate) –  newts from the pond in the Danson Park Old English Garden yesterday (Sept 18th). I have looked for adults here previously, but never seen any. This would appear to be a new site record. Over the course of last summer several people took turns at rescuing Froglets, but there were no Frog tadpoles this year, and Toads (a Biodiversity action Plan species in decline) were seen mating in the pond a few years ago.

Unfortunately, the overhanging edge slabs prevent these animals from getting out, which is necessary for them to go and find food and winter hibernation sites. Friends of the Shuttle had gone some way towards making an exit ramp of large rocks, but this has either been interfered with or was for some other reason below the water line and too far below the rim. A solution might be to remove some of the slabs and bevel back the edges at these points, since the newly-metamorphosed ‘babies’ can to some extent climb the zinc(?)-lined part of the vertical sides through suction when wet, though this won’t help any much heavier adults.

In any event, there needs to be a permanent physical fix so that the pond becomes a net contributor to amphibian populations in the park, to which it is well-suited on account of being free of any fish which would eat frog and newt tadpoles, or it will continue to be a death trap and a net drain as both post-breeding adults and their young fail to escape and drown trying, or starve first.

Joanne left a great legacy from her earlier role in the shape of the Friends of the Shuttle group,  which has recently expanded operations to fill the void in environmental action at Danson Park, and serves on its committee.

She will be running a water quality monitoring training event at Erith Yacht club in October. Details as follows:

Thames River Watch – Water Quality Monitoring Training at Erith Yacht club. October 17th.

As a Thames River Watch volunteer, you will spend just a couple of hours each month to help us build a better picture of the health of the tidal Thames.
This day-long training session will provide non-experts with the knowledge and tools to become a Thames River Watch surveyor.
The session will include:
An introduction to Thames River Watch
The story of London’s River
The tidal foreshore environment
How to undertake water quality tests
How to report your findings
The session involves indoor learning and a practical session on the foreshore.
Please note: you must register with the training programme before you can book onto this event: http://www.thames21.org.uk/thames21-training-registration/

Next ‘Bexley Wildlife’ social to be held Wednesday October 14th

After the success of our first event, the ‘Bexley Wildlife’ team (a web platform collaboration between Bexley Natural Environment Forum and the Greener Bexley Charity) are pleased to invite ‘followers’ and other interested people to join us at another social on Wednesday October 14th from 7p.m. at Bexley Village Library. The library is situated at the junction of Bourne Road and Albert Road, near to Bexley railway station and various bus routes.

Light refreshments will be available for purchase from the library cafe, but attendees are welcome to bring their own, including alcoholic beverages. Some of us may repair to a local hostelry afterwards, and people will – of course – be free to come and go as they please.

The evening will be largely informal, but we are again lining up three short talks of up to 10 minutes duration each to provide a bit of focus. We have decided this time to have them all grouped together early on rather than spread out during the evening, so as to provide a prompt for further discussion and to avoid breaking up everyone’s conversations later. The talks will probably start sometime between 7.30 and 8.00 p.m. Precise details will be furnished nearer the time.

Our friends from just over the border at Ruxley Gravel Pits, a Site of Special Scientific Interest, and the Lesnes Abbey Woods Conservation Volunteers have agreed to speak about their sites, the wildlife on them and their management work. We are awaiting confirmation on the third slot, but have several potential subjects we can fill it with.

The event is open to anyone with an interest in wildlife and sustainability issues in the Borough, whatever their current level of expertise or involvement. Our aim is send everyone home a little bit better informed and more enthusiastic about the subject, as well as with some new friends and useful contacts!

The event will end at about 10.00 p.m.

Last chance to save the parks?

Last chance to object to park sell off if you haven’t already.

Large park at risk of development. Houses or open space?

Large park at risk of development. Houses or open space?

https://www.surveymonkey.com/r/openspaces2015

What I said. Jonathan Rooks.

I put this same comment in all four boxes (each site) as none of them should be sold off.

I object.

Public Open Space, whatever its size plays an important role in the welfare of the local residents.

1. Research after research shows the association of access to green space with improved physical and mental health.

2. The proper management of public open space allows local authorities the opportunity to mitigate against climate change.

3. In addition, the proper management of public open space can play a significant role in the preservation of wildlife

The three above all fall in one way or another under the responsibilites of a local authority.

Further, the proximity of public open space has been demonstrated to increase the value of property.

All four of these points should be of concern to a local authority and quite apart from any moral concerns should be sufficient to ensure the protection of public open space.

With the increased development of the borough, intensification of development and increasing number of homes without gardens, the Council by any serious measure of public welfare, should be trying to increase access to public open space, not reduce it.

Bexley as a borough is quite well endowed with public open space. This is not a happy accident. It is the result of former Councillors and Council Officers (of a number of authorities) taking the effort to protect their community, particularly during the inter-war years when there was extensive development in Bexley borough.

This Council is going to betray the efforts of 80+ years of civic pride because they have failed to make adequate provision to protect the borough. This is shameful.

Failure to ensure adequate financial resources by keeping a Council Tax that was too low to meet costs simply for political reasons so as to ensure the re-election of a Conservative council. Shameful.

Failure to adequately investigate alternative ways of managing public open space so as to substantially reduce costs. Very disapointing.

With Bexley Council’s contractors regularly doing uneccessary work and no serious consideration of alternative methods of site management Bexley Council is showing a failure of leadership and will bring disgrace on itself by developing public open space by demonstrating that it cannot be trusted to look after its assets.

The proposal to dispose of public open space of any size should be dismissed and the Council should work with local experts and groups to reduce the costs of management of sites.

Page 2.

Selected. Substantial reduction in grounds maintenance option as this actually does offer the opportunity to reduce costs and improve the sites in many ways, and not just for wildlife.

I made the comment.

False alternatives.

You could have avoided all of this if you hadn’t artificially held down Council Tax for political reasons.

The Council has not seriously reviewd how the sites could be alternatively managed and should do this before it even begins to think about disposals.

Don’t forget to click the Done button at the end.

GLA committee seeks views on ‘growth’ vz environment – by 18th September

The Greater London Assembly Environment Committee is seeking evidence on the environmental pressures of London’s growth, focussing on:

  1. Energy supply, demand and distribution
  2. Water management
  3. Green infrastructure

Deadline Friday 18th September.

For details see:

http://www.london.gov.uk/mayor-assembly/london-assembly/investigations/environmental-pressures-of-londons-growth

There are already several examples of the negative consequences of this in Bexley. These include:

  • Bexley Council agreeing it will have to bin the ‘Core Strategy’ (its central strategic planning document) because it has decided to jack the proposed house building target for the next 15 years from the 4,500 agreed only 4 years ago to 22,000, which suggests a 20% increase in the Borough’s total population over the 2011 census.
  • Allied with this is the rest of the Council’s 20th century ‘Growth’ strategy, laughably called a ‘vision’. We are told its supporters are the people we should trust to deliver this bright new future without destroying the things we value (and these are not spelt out, of course). There is no plan to tackle resource consumption so that this major population hike does not deliver a net increase, despite the UK signing an international treaty to get usage within sustainable limits by 2020 in order to preserve biodiversity, and the core strategy being riddled with the word ‘sustainable’. What they really mean, of course, is ‘sustained development’.
  • Support for a Belvedere road bridge over the Thames and what is tantamount to support for another at Gallions Reach, both of which will pour traffic into Bexley despite this blindingly obvious problem being the reason the Council objected to the previous bridge proposal.
  • Open space sell-off plans, now explicitly linked to the Council’s ‘growth’ agenda, which is also in part responsible for the more than 18 month hold up in approving the Sites of Importance for Nature Conservation review.
  • The refusal to countenance turning over brownfield adjacent to Erith Marshes to nature conservation use, so as to deliver a modest increase in size for this SINC of London importance, despite allowing erosion elsewhere in the shape of the Veridion Park development, and knowing that a big chunk of Crayford Marshes SINC still has a ‘development’ axe hanging over it.
  • Unanimously approving building on nearly three quarters of the Erith Quarry Grade 1 SINC, with ‘mitigation’ limited to leaving a strip of woodland (which was already protected by saved UDP policies), and a small fragment in one corner, which is too small for the density of reptiles already found on the site. No attempt is being made to try and make up for this major loss of important scrub habitat by changing management regimes at other sites of lower wildlife value or by utilising other brownfield land.
This view from Hollyhill across to Erith Quarry will soon be ruined by a major 'development'. The 'developer's' glossy document about impact on views avoided showing any of the several panoramic views and just gave the impression trees blocked any decent vista. (Photo: Chris Rose)

Frankly, this is all stable door after the horse has bolted stuff from the committee,  given the lack of opposition to Boris’s overt support for increasing London’s population from 8 to 11 million, lots more concrete and his associated ‘densification’ agenda, leavened as it is with pages of greenwash (because not legally enforceable) about ‘green infrastructure’.
