Effects of extreme rainfall still evident at Hall Place.

A trip to Hall Place on a sunny Sunday 13th shows that this winter’s extreme rainfall is still having an impact locally even several weeks later.

The Sunken Garden lives up to its name ……

Flooded Sunken Garden Hall Place 13th April 2014

Normally one descends a few steps and can walk round the flower beds in this sunken garden. It usually looks great because of the surrounding flowering Camellias. Since the winter this area hasn’t properly drained away.

Many visitors to Hall Place are not aware of the important role the site plays in helping to prevent flooding further down the Cray, in Crayford.

Where the river enters Hall Place grounds here is a bend and located here is an ‘overspill gate’ where the river can overflow its banks safely as the river level rises.

Overflow gate at Hall Place on CrayJust the other side of the gate is a concrete base so that the waterfall from the overspill doesn’t erode around the banks. The diverted water then flows through the channels in the grounds and on into the larger park area (between the river and the railway line).

It is unusual to see water in these channels and they are usually kept mown as vegetation might slow down the removal of any flood water. The bottoms may be damp at times, but to see them with significant amounts of water is rare.

Currently parts of them, two months later, still look like ditches. There is water still in them and an interesting vegetation is growing. Now they look like something of wildlife interest rather than odd mown ditches.

The river still seems high and a great deal of water is till coming over the fall at the former mill site (outside the cafe). We still think this might make a good site for a small hydroelectric power generator – carbon free energy for Hall Place and a useful educational site. Maybe one day.

DSC00913The other project that needs to be done here is a fish pass, particularly one for eels and I know that this is being considered by the Cray Catchment project.

While enjoying the gardens we also took a look at the wildlife area which is used with school parties. A bird hide over looking the river and several feeders and the pond especially designed for pond dipping. We know this is popular with children and schools, today it was also popular with Mallards.

Thames21 at The Old Mill, Bexley Village

Michael Heath and his team working this morning on the River Cray in Bexley Village at The Old Mill.

Passing through the Village I bumped into Michael and his team hard at work.

Work Michael described to me as “a cross between practical conservation and gardening”, reflecting the fact that there is a need for more vegetation management here on the banks than on most stretches of the river so as to keep passers-by happy with a neater appearance than we might want elsewhere.

Unfortunately, I didn’t have my wellies with me….

The bankside vegetation was being cleared of nettles and brambles, the mid-stream weeds cut back so that the stream doesn’t clog and some channels were being cut into the mid-stream island to give a greater variety of habitats and force of flow to benefit aquatic invertebrates.

There are a number of dates in our calendar for work parties on The Cray and the other rivers in the Borough.

St. Paul’s Academy help with conservation work

St. Paul’s Academy and Thames21 on the River Cray

sp8346em

The Thames21 River Cray Project welcomed students from St Pauls Academy Greenwich on Saturday 1st March to Crayford. The school again joined with Thames21 volunteers at the Lower Cray and cleared rubbish, recyclable materials and fly tipping from the River Bank and the Thames Road Wetland at Barnes Cray, This was one of the final opportunities to clear rubbish from the wetland before the onset of spring.

St Pauls Academy have adopted the River Cray as one of their environmental projects and have under the leadership of Geography Teacher Gordon Davis, and his staff Rebecca Hurley and Sean O’Connell, over the last two years completed a number of river habitat improvements at Erith salting’s, Foots Cray Meadows and the Thames Road Wetland,

sp8334em

At the beginning of March, 18 year 10 students worked all Saturday enthusiastically removing litter which filled a large skip with assorted rubbish from the wetland and river banks including 46 bags of recyclables. The river bank footpath here was strewn with empty drinks cans as well as other discarded personal items. The student’s willingness to come along out of school and remove the rubbish with Thames21 as part of their environmental project supports local residents and sends a message that such irresponsible disregard for the river habitat and local communities is unacceptable.

Michael Heath Thames21 project officer for the River Cray said ‘It’s great to again work with St Pauls Academy, the students seem to have adopted the Cray and they turn up out of school whatever the weather get stuck in and again they made a difference to the Wetland and the Barnes Cray River Bank which needed attention’

Gordon Davis Teacher said “The students have benefited from working with Thames21 as it equips them with workable skills ranging from team-building, collaboration and independent learning, which are easily transferable to the classroom environment. It benefits our students by making them stand out from other applicants to colleges, apprenticeships and universities. It also supports internal schemes, such as the Jack Petchey Award, and externally through initiatives such as the Duke of Edinburgh Award. It supports students working together across different year groups and so enhances community cohesion in the school. Potentially it makes the students aware of environmental issues whilst being stewards of their communities. The transformation of these students into adults is one of the rewarding experiences of completing volunteering.”

Patrick Winston, Principal of St Paul’s Academy states “I am delighted that our students have had the opportunity to be involved in this programme. Congratulations to Gordon Davis and his team of leaders.”

Thames21 is an environmental charity (registered number 1103997) which works with thousands of volunteers each year to improve London’s rivers, canals and ponds.

The Thames Road Wetland in Crayford was created in 2007 by the London Borough of Bexley. This compact site of 2.4 ha (6 acre) presents a number of management challenges. Never-the-less it packs a large and impressive punch in terms of the species to be found here. Noted for a list of plants that are uncommon in London and Kent, it hosts twelve species of odonata, seven species of reptile and amphibian, and a growing suite of breeding and visiting birds, including one of the few Bittern’s recorded in Bexley. Being an urban wetland the site needs to be tended during the winter months to remove existing and new rubbish and to retain its wetland and variety of habitat when wildlife disturbance will be at a minimum.

Spring Summer events at Crossness Nature Reserve

Dear Friends of Crossness Nature Reserve,

I hope this finds you all well and geared up for Spring/Summer. The bird
hide at Crossness is now complete and looking amazing. Although it hasn’t
had the official ribbon-cutting opening ceremony yet, it is indeed open
and I would urge you to come and take a look. You can’t fail to be
impressed as it is such an amazing building (two-story, octagonal in
shape), and what’s more, it is dry, warm and draught-free, unlike our
previous hide for those of you that were familiar with it. A wildlife log
book (ring binder) is located on the table of the ground floor, so please
be sure to record your wildlife sightings; I can’t stress enough how just
important your records are for the reserve.

We have a few events coming up that you may be interested in attending:

10am Weds 2nd April  – VOLUNTEER WORK DAY: Litter pick of the Crossness
Nature Reserve southern boundary path. As many of you know, this path gets
heavily littered as it gets windblown from the adjacent dual carriageway.
Come along and help us give this lovely path a spring clean. Norman Road
gates will be open for vehicular access to the reserve. Refreshments
provided

10am Weds 30th April  – VOLUNTEER WORK DAY: Vegetation raking of Long
Meadow. This large area will have been cut ahead of the work day, but if
the vegetation is left it will put too much nutrient into the soil and
promote the growth of thistles and nettle in an area that we are trying to
establish as a wild flower meadow, so please come along and help us rake
and remove the vegetation, giving the insect-friendly plants a chance to
thrive. Meet at the vehicle entrance to the Crossness Southern Marsh
(under the red fly-over on Belvedere Road; park on Belvedere Road or at
Southmere Lake). Refreshments provided

9am Thurs 1st May – MIDWEEK BIRD WALK with Ralph and Brenda Todd. Join us
for a morning bird watching walk of the nature reserve, identifying birds
by sight and sound, and taking full advantage of the new bird hide. Meet
on the nature reserve where the Norman Road gates will be open for
vehicular access. Refreshments provided

9.30pm Fri 30th May – AMPHIBIAN TORCH SURVEY of Crossness Nature Reserve
water bodies (some areas will be inaccessible due to bird breeding).
Several pairs of eyes are better than one, and torch surveys of water
bodies are fascinating; not only will we see newts in the ponds/ditches,
but it is a fantastic opportunity to see all sorts of other aquatic
creatures. The last time we did this, we were armed with nets and sampling
trays and probably spent more time enjoying the drama of water scorpions
and cased caddis-fly larvae, than we did identifying newts! It’s great
fun; guaranteed to bring out the child in you as well as helping the
reserve to gather more amphibian/aquatic invertebrate records. Bring a
good strong torch if you have one, or whatever you have to hand if not.
Norman Road gates open for vehicular access onto the reserve. No
refreshments provided for this event

9.30pm Fri 27th June – AMPHIBIAN TORCH SURVEY of Crossness Southern Marsh
water bodies (some areas will be inaccessible due to bird breeding). For
all the same reasons as above, feel free to join us for some nocturnal
activity on the marshes. We will be looking at recently-created water
bodies, so it’s anybody’s guess what will be revealed. Bring a good strong
torch if you have one. Meet at the vehicle entrance to the Crossness
Southern Marsh (under the red fly-over on Belvedere Road where you can
also park your car). No refreshments provided for this event

Jun/Jul (date and times to be confirmed) – CREATURES OF THE NIGHT Join us
for all things nocturnal on Crossness Nature Reserve. We’ll be setting up
moth traps and wine ropes with a lepidopterist, using bat detectors to
find bats, and having our eyes peeled in search of barn owl activity. This
is weather dependent with a warm, overcast evening being ideal for
mothing, so time and date will be confirmed nearer the time, but it is
worth registering your interest if you think you would like to attend.

10am Weds 2nd Jul – VOLUNTEER WORK DAY: Ragwort pulling on Crossness
Southern Marsh. Come and join us for some fun in the sun as we do our
annual ragwort pulling. Ragwort is the food plant of the Cinnabar Moth, so
we ensure that we retain plenty of this plant in the non-grazed areas, but
it is also toxic to livestock – and horses particularly – so we have a
duty to control it in the paddocks. The best way to do that is to pull it
up from the root by hand, and it needs as many pairs of hands as possible
to do this, so please join us at the vehicle entrance to the Crossness
Southern Marsh (under the red fly-over on Belvedere Road; park on
Belvedere Road or at Southmere Lake). Refreshments provided

Aug (date and times to be confirmed) – BAT WALK at Southmere Lake and
Crossness Southern Marsh. This is a lovely time to see bats out hunting,
and Southmere Lake provides great spotting opportunities with close views
of hunting Pipistrelles and Daubenton’s bats guaranteed. Meet at Southmere
Lake car park. Time and date to be confirmed as I am trying to get a venue
to do a presentation before we go out on the hunt. This event will also be
suitable for children; hopefully they’ll get away with a late night since
it will be the school holidays. Bring a torch. No refreshments for this
event.

Although it means that you are in no way committed to attend either way,
it would help me to have a rough idea of numbers that may come along to
these events, because it helps with the parking and catering arrangements.
So, even if you change your mind down the line, if you think you might
like to come along, please do drop me a line to let me know – thank you.

I look forward to seeing some of you at forthcoming events, or indeed
wondering around the reserve.

With kind regards

Karen

Mammal survey 2014

Hedgehog scavengingNational charity PTES are conducting another annual mammal survey asking people to observe mammals in their local area.

The survey starts on Monday 31st March and all you have to do is spend some time observing a chosen site (such as your garden or allotment, a churchyard or local park) each week, noting any mammals you see or the signs they leave behind.

Details on the project on the Peoples’ Trust for Endangered Species website at: http://ptes.org/index.php?page=441

They have an excellent guide to spotting mammals which you can access from their website or here: https://app.box.com/s/mt2uje00qfl2cdzzu3jv

Also a very interesting report showing the results of last year’s survey at: https://app.box.com/s/q7dqhosh73bnfk21lawk

And hopefully we will see more than just foxes!

Bumblebees out early

David Rea of Ruxley Beekeepers reports that he and a colleague were called to a primary school where a colony of buff tail bumbles is in full operation, in a flower bed right in the middle of the reception class playground.

Buff-tailed Bumble Bee

Of course there are plenty of queens about now, feeding and searching for nest sites, but this colony must have broken all records for starting early. Lots of workers were charging in with loads of pollen, so there is plenty of brood down below, and the teacher said they had been at it for at least a month.

Our ‘no need to panic’ advice turned into a class lesson for the kids, and then a mass gathering whilst I released the sample I’d caught for close inspection. Good start to the season, and means its bound to be 2ft deep in snow by Easter.
