30 Days Wild – Day 27

That unusual combination of hot and windy today, the breeze providing some, but not  a lot, of relief from the strong sunshine, although increasing the risk of getting unknowingly burnt. The volunteers were tidying up around the Centre and trimming and pulling nettles from the path edges.

The extra warmth is good for dragonflies, snakes and butterflies, although it makes them very active and so difficult to get close to. There are, at last, dragonflies to be seen in fair numbers, most though seem to be emperor or black-tailed skimmer. One species that I thought I might have missed was downy emerald, typically a late April dragonfly at Blashford, that you see through May and tails off in June. So I was pleasantly surprised to find a female beside Ivy North Hide as I locked up. It was also pleasing to get a picture as this is a species that does not often land within reach, often perching high up.

30 Days Wild – Day 20

A slippery sort of a day, blue sky to start then rain, then warm sun and eventually heavy rain, it was hard to know how many layers and of what type to wear and every time I went out I got it wrong. The wildlife seemed equally confused, at Ivy South Hide as I opened up in thick cloud the grass snakes were “basking” on the tree stump.

By the time I set out with the volunteers at 10:00 to work on the eastern shore of Ibsley Water, the sun was strong and the sun block was out in force. Ten minutes later when we got there, grey clouds were threatening and curtains of rain could be seen falling to the south-west. Luckily, and to my surprise, we got away with it and managed to return still more or less dry. On the return journey I noticed a mullein plant with the telltale tattered leaves caused by munching mullein moth caterpillars.

Our tern rafts have mainly been occupied by gulls again this year, this is to be expected as gulls far outnumber terns. There are about twenty pairs of terns nesting though and many now have chicks.

There are still a few common tern seemingly loafing around on Ibsley Water, I assume off-duty birds whose partners are still sitting on eggs, but perhaps non-breeders.

The picture, with wings open shows a clear identification feature of the species, the darker outer primaries. The reason for this is that the outer four or five of the wing feathers much older than the inner ones and so more worn. The white edges wear away more quickly which means older feathers look darker, forming a definite dark wedge in the outer-wing. The reason this helps with identification because the most similar tern species, the Arctic tern moults all of its wing feathers in one continuous sequence, meaning that there is no such contrast between the newest and oldest wing feather, making the wing look the same all along its length.

Warm wet weather is perfect for slime moulds, the really weird end of nature and a group I have featured a few times before.

This one has various names, one is troll butter, but there are many more.

The bark chippings in the raised beds at the Centre also has some, at first I though just one type but a closer look suggests at least two. A close look is essential as the fruiting bodies are very small indeed.

30 Days Wild – Day 13

As I was wondering if I should put on a fleece under my jacket in an effort to keep both dry and warm, it was good to think back to those balmy days of short-sleeves in February and know that it would be warm again, sometime. Needless to say, despite it being mid-June, it was not a day for insects, or much else.

The stalwarts of Blashford’s Brilliant Volunteers worked through it all though and we made a good job of finally clearing the yard of scrap metal and old tyres. Sadly we are “donated” rather a lot of rubbish, not generally by our visitors, but in the form of fly-tipping. I suppose it is something we should feel “Wild” about, but after years of working in the countryside it, sadly, has becomes an expected part of the job.

Although I have said our reserve visitors are generally very good alt not leaving litter, there have been a few incidents recently of mess being left at the Goosander Hide, probably int he evenings. There is some indication of a degree of general anti-social behaviour as well. If anyone is on the reserve at any time and sees such things going on it is very useful to have such details as it is easy to get. These issues are difficult to tackle so any information is useful, an email to the Blashford Lakes email or if ongoing int he daytime a call to the office or one of our mobiles is very helpful, the contact details are posted in the hides.

One sign of summer at Blashford was in evidence though, although it was necessary to peer through the drizzle to see it, the ponies are back grazing the shore of Ibsley Water.

The weather has been a problem in lots of ways, one of them is that it is preventing us from colour-ringing our usual sample of young black-headed gull. It seems likely that most will have fledged before we get the weather to go and ring them.

Let’s hope for some more summery conditions next week.

30 Days Wild – Day 11

Following the recent and unseasonable wet and windy weather the volunteer task on Tuesday was first to walk all the paths and check for fallen branches and other hazards. With five miles of paths this takes a while, especially when there is clearance to be done, not exciting work but very necessary.

This same weather has been having quite an impact on nesting birds, it makes food harder to find for some, although rain makes worms easier to find. Open nests can get wet and wet chicks can chill very quickly. Some species with young that leave the nest soon after hatching are especially vulnerable. However many are still doing well, I came across this brood of coot on the Ivy Lake Silt Pond as I was locking  up on Day 11.

Some of the black-headed gull juveniles have fledged, but many are still wandering around their island or on the rafts, they are mostly quite large so should cope with getting wet reasonably well.

The nesting terns are due to start hatching soon, I do worry that very small chick will be at great risk if this period of cool wet weather continues. Very small chicks have fluffy down and a very high surface area to weight ratio. This means if they get wet, the down holds onto the water and they can chill very fast and die. In addition wet, windy conditions make it harder for the adults to find and catch food. Crossed fingers everyone, let’s hope the rain eases and the wind drops soon.

30 Days Wild – Day 6

The Blashford volunteers were out in force today and we were pulling Himalayan balsam along the Dockens Water, I am delighted to say that we found very little until we got down to the very lowest part of the stream, just where it leave the reserve. All the years of work seem to be paying off. This lower part of the stream is an area where we have been allowing the stream “to do its own thing” a little bit of rewilding, if you like. This has been the approach for over ten years now and all we do in there is clear rubbish washed down the stream and control invasive alien species, such as the balsam. It has developed into an amazing area of habitat.

We came across a strange patch of red in the stream at one point, I think it is a red alga presumably exploiting some mineral seepage, but I may very well be wrong about that!

The red stuff!

The reserve was generally quiet, but as I locked up the Tern Hide I noticed a second calendar year Mediterranean gull close to the hide, it had a colour-ring on the left leg and luckily it was showing well enough to read the code.

I think it was ringed in Ireland and I will update when I have found out details form the scheme organiser.

Rafts, Birds and Bees

It’s that time of year again, the tern rafts are going out and the migrant waders are on the move. On Tuesday the volunteers got two rafts out onto Ivy Lake, after wintering on the shore.

They were occupied by common tern within minutes, although black-headed gull also arrived in numbers and by the end of the day were the only species present. This highlights one of the big problems that terns have these days, as their nesting habitats reduce they are competing more and more with gulls and usually lose out to them.

Yesterday’s migrant birds were mainly waders heading to the high Arctic and included a common sandpiper, a bar-tailed godwit,

The waders that nest with us are all displaying but none seem to have really settled down yet. Little ringed plover are especially in evidence near Tern Hide.

Although it has got cooler the spring insects are still in evidence and some of the earlier season species are beginning to disappear for another year. One such is the rare grey-backed mining bee Andrena vaga, there are only a few females to be found now, but as they feed on willow pollen their food will soon run out.

If you look at a solitary bee nesting bank there are usually lots of, what at first, look like wasps, but these are actually parasitic bees. Many are very specific as to their host species, I came across two species yesterday. I found what I think was Lathbury’s nomad bee, which uses grey-backed and  the commoner ashy mining bee as hosts.

I also found lots of painted nomad bee, which visits the nests of the common yellow-legged mining bee.

Work continues on the parking area close to the Education Centre, which means that it will not be available for parking until after the weekend, please take note of any signs to keep safe on your visit whilst we have machinery working on site.

Substitutes and Declines

It was feeling very spring-like today, I got very warm as I worked with the volunteers felling some grey alder beside the path to Lapwing Hide. These trees were planted as a “substitute” for native alder, which is not a hard tree to source, when the restoration planting was done after the gravel working ceased. Sadly truly native trees are not always specified in planting schemes, even when they are supposedly done for nature conservation and even when they are, substitutes are often allowed. Often even if the tree species is native they are not from a UK source, importing trees has brought us several diseases that have significantly impacted upon native woodland. These imports are also often adapted to a different climate so will flower or leaf earlier out of sync with native insects. Let’s have more native trees that are really native, ideally grown from the seed of trees as local to the planting site as possible.

Wild daffodil just coming into flower, a good indicator of remaining ancient woodland at Blashford Lakes.

Having said all this planting trees is an often seriously over rated activity, if they establish well we end up with secondary woodland that will not be more than a pale shadow of an ancient woodland in even a thousand years. The best way to extend woodland cover is to allow existing ancient woods to grow outwards, letting them seed into neighbouring open ground, something that will happen naturally in most places if grazing or mowing are stopped. This way we will get locally adapted trees establishing where they will do best and other species can move out from the old wood into the new. It will also serve to buffer the older woodland and reduce the distance to the nearest neighbouring wood. I am prepared to make an exception for hedges though, so many of these have been lost that replanting is the only practical way to get them back, but the need for locally plant stock remains important.

There has been a good bit of coverage of the severe global decline in insect numbers in the media over the last few days and it is very alarming. A series of studies are now coming to very similar conclusions and these are that insects are in trouble globally with significant declines not just in developed western Europe but in tropical forests as well. Insects may be small but their abundance and diversity mean they are vital to the effective functioning of almost all terrestrial ecosystems. They are predators and prey, decomposers, pollinators and grazers, in fact they are almost everywhere and everywhere they are, they perform essential functions. I have run a moth trap for many years monitoring the species caught before releasing them and I can attest to a great drop in numbers over the years, I see as many species but none in great abundance as I used to.

Pale brindled beauty, a typical late winter species, there were two in the trap last night.

Over the last few weeks things have been a bit hectic on the reserve with work going on all over the place, the new pond is being dug behind the Education Centre and preparations continuing for the installation of the new Tern hide next month. We are doing our best to keep the reserve up and running in the meantime, but there will be occasional interruptions to normal service, such as temporary closure of the main car park or limitations on the use of parts of the car parks.

Out on the reserve two bittern have been seen a number of times recently at Ivy North hide as have two great white egret. I am especially keen to try to record the last sighting of “Walter” our colour-ringed great white egret, he usually heads off back to France around this time of year so any definite sightings gratefully received. At the weekend an otter was seen at Ivy North hide and this morning I have very, very, brief views of one near Ivy South hide, so it is well worth keeping an eye out.

Tern(ed) Down

Well the deed is done, today we took down the Tern Hide, after a bit of a slow start we got into our stride and it came down more or less in sections as planned. It was in pretty good condition for the most part, until we took up the floor, the supports were in a poor state. It will be about two months until the new hide is up and ready, this might seem a long time, but I had only a couple of days each week when there are enough of our brilliant volunteers to tackle this scale of job and it could not have been done if the day had been windy, so I decided to allow a two week window to get it done. Before the new hide can go up we have to remove a large slab of concrete, which will take a while, so extra days might prove useful later on.

Meanwhile, back at the Education Centre, progress on the pond has been slower, but hopefully will pick up tomorrow. The car park there is now usable again, the surface is not the finished article yet, the final layer will have to wait until all the other works are complete, but it is fine to park on. There is still fencing up in places with some restrictions on access but the paths are open as is the Centre and hides. I am still hopeful that the path from the main car park to Goosander hide will be opened up soon, now that all the works have been finished.

I did not hear many reports of wildlife today, although the yellow-browed warbler was apparently seen in the brambles right in front of Ivy South hide. Locking up I had good views of water rail at Ivy North hide, I also heard a Cetti’s warbler singing and saw a great white egret roosting in the trees. The two first winter Caspian gull were again in the roost on Ibsley Water along with at least one Mediterranean gull.

At lunchtime I saw a common toad swim past the camera on Pondcam, my first of the year, although I am not sure if I can count “seen on Pondcam”.

Thinning

Not a reference to the effects of advancing age but to today’s volunteer task on the reserve, which was felling some sycamore trees to open up some space. In places we have dense stands of very tall, thin sycamores which tend to over-top and then shade out other species. To reduce the negative effects of this we are thinning out a lot of the smaller trees, especially where they are growing amongst other species such as oak. It was the perfect day for felling, at least until the rain started, being cool, so I did not overheat in the protective chainsaw gear and calm, so the trees would hopefully fall where I intended them to.

By the end of the day we had cleared quite a few trees, but the more we took down the more there seemed to be! At the same time there was a more open feel to the area so we must have done something. We did come across quiet a few small, self-sown hazel and even one covered in honeysuckle and these should benefit from some more sunlight.

I left a number of the stumps fairly high, this allows me to ring-bark the stump reducing the chance of it growing back, without using pesticide and also gives the opportunity to make some cut slots and holes to allow rot to get a hold and make habitat for various invertebrates.

Chainsawing for most of the day does reduce the chance of seeing wildlife somewhat, but not completely. Locking up the hides at dusk I was lucky enough to see both great white egret and bittern at Ivy North hide. I understand the yellow-browed warbler was again near Ivy South hide and out on Ibsley Water there were peregrine, Mediterranean gullyellow-legged gull and black-necked grebe, but no sign of the lesser scaup, perhaps it has moved to Blashford Lake where it spent much of its time last winter when it was here. At Woodland hide there was also a brambling reported, perhaps the same bird that Tracy saw yesterday.

A Fine Day on the Reserve

Thursday dawned calm and slightly misty with a promise of sunshine to come.

Misty morning at Ivy North

Early morning over Ivy Lake

I am not sure if they were doing the Wildlife Trust’s 7 Days of Wild Christmas, checkout #7DaysofWildChristmas for more on this, but there were lots of visitors on the reserve on Wednesday and they certainly saw a lot of wildlife.

From Ivy North hide the bittern was seen by most who were willing to spend a little time looking and some had excellent views. The picture below was sent in by John Parr after he took it on Saturday from Ivy North hide.

As well as the bittern, water rail and Cetti’s warbler were also frequently on show from Ivy North hide. Further out on Ivy Lake a good variety of ducks were on view, there remains an unusually large number of pochard around, with up to 100 on Ivy Lake alone at times. At dusk a single great white egret roosted in the trees.

At the Woodland hide the usual common woodland birds have now been joined by a few reed bunting, attracted by the seed spread on the ground, we have still yet to see any brambling though.

On Ibsley Water the flock of linnet was again feeding on the shore near Tern hide whilst out on the lake up to a dozen goldeneye, over 40 pintail, 200 or so wigeon and the single black-necked grebe. In the late afternoon the gull roost included a Caspian gull, but there was still no sign fop the ring-billed gull, which looks increasingly likely to have moved on somewhere.

As it was Thursday there was a volunteer task on the reserve and six volunteers joined me in doing some willow scrub clearance and pollarding in the reedbed area between Goosander and Lapwing hides. The area is a former silt pond and had grown up with a very uniform cover of closely spaced and rather weakly growing willows, not a habitat with great wildlife value. By opening up clearings and making pollards of the stronger growing willows we can diversify the habitat, making it suitable for a much wider range of wildlife. In particular the open clearings have proved very popular with the areas strong adder population.

The mild weather continues and there are signs of this all around the reserve. On the path to Ivy North hide I found a red campion still in flower.

The mild conditions, along with the damp conditions are proving good for fungi, with many particularly small species to be found if you look closely. One of the commonest species on well rotted wet logs is the candle snuff fungus.
