30 Days Wild – Day 15: Trying to Impress

I was out on the eastern side of Ibsley Water with the volunteers this morning to clear the areas we cut and which are grazed by ponies of ragwort. It is toxic to animals, but they will usually not eat when it is growing, however they will if it is cut and gets mixed with grass or hay. At one time it was one of the commonest plants in this area but now it is much reduced and overall the grassland is looking much better, with quite a good range of species. A couple of highlights this morning were several patches of corky-fruited water-dropwort.

Corky-fruited water-dropwort is an Umbellifer, one of the carrot family and is very attractive to insects, this one had lots of pollen beetles on it. It is quiet frequent in unimproved grasslands in a swathe roughly south of the M4, so it is pleasing to see it at Blashford where the grassland is still recovering from the ravages of mineral extraction. Another find was knotted clover, a plant of dry sandy places, often near the coast, I am not sure if I have found it at Blashford previously.

At lunchtime I tried the pheromone lures for clearwing moths again, completely without success. However I did spot a handsome black-and-yellow longhorn beetle.

After doing various odd jobs in the afternoon I went to lock up the hides and found a pair of crab spiders on a hemlock water-dropwort flower head, The male is quite different from the female and a lot smaller so he has to tread carefully if he is not going to get eaten.

It seemed it was not only the spiders that were making plans, on a nearby ox-eye daisy I saw a female hoverfly Eristalis horticola, with a male hovering low over her and darting from side to side. I am not sure if she was impressed but he was trying hard to dazzle her with his advanced hovering skills.

I also found another slime mould, on the same log as the one the other day, although this was clearly a different species.

The only new bird sighting of note today was of a first summer little gull as I locked Tern hide. It was pleasing to see that the single oystercatcher chick from gull island has fledged and that the remaining one near Tern hide is close to doing so. In additions the single large lapwing chick is also close to flying and two of the smaller ones are still going strong. Even better was a sighting of two well grown little ringed plover chicks today. On Ivy Lake the common tern chicks are growing well and most broods seem to still be of three chicks.

30 Days Wild – Day 1: Weird Stuff

Here we are again, another June and another 30 Days Wild, I will try to keep up this year and post something every day.

I was at Blashford today with the volunteers tidying up on the southern shore of Ivy Lake, clearing away some old tern rafts and doing a little Himalayan balsam pulling, actually the volunteers did these things, I cut a few brambles and set up the telescope to count the nesting common tern. I am pretty sure we now have 25 pairs on the rafts with nests and eggs, possibly 26 pairs. So with five pairs on the Pound we have reached thirty pairs for the first time! This has been a really successful project and almost entirely the work of our great volunteer team. Over the last ten years the Blashford terns have consistently produced more flying chicks per pair than any other local colony, with many pairs achieving the magical 100% success rate, laying three eggs and fledging three chicks. Over the last year we have made a whole set of new rafts funded by a grant from Hampshire Ornithological Society (HOS) to a design refined and honed by our volunteer team.

During the course of the work we came across two grass snake, a nest of bank vole and a number of dragonflies including an emperor, scarce chaser and broad-bodies chaser.

The weirdest thing I saw today though was an old favourite of mine, a slime mould, these are strange organisms that usually live as single cells but aggregate to form sporangia and it is this stage that we can see on old wet logs. The one I found today near the Woodland hide was a Stemonitis, possibly Stemonitis axifera. They take less than a day to aggregate, develop and produce spores and then disappear.

Regulars will be pleased to hear that the two lapwing chicks and the two oystercatcher chicks are still doing well outside Tern hide, with an additional and larger, oystercatcher chick in the distance on Gull Island as well.

You can see various 30 Days Wild stuff on Twitter via #30DaysWild and probably lots of other places too and it is still not too late to join the over 45,000 people who have signed up to do something wild on 30 Days. Our environment is vital to our wellbeing, physical and mental health and it is where we live, despite this it is not getting much attention

Bee-flies, Butterflies and a Good Tern

Another very warm spring day at Blashford today and the air was full of all the sights and sounds of the season. There are now chiffchaff and blackcap singing in many parts of the  reserve and there were reports of a willow warbler singing near the Ivy North hide.

The volunteers were working near the main car park today, where we were buzzed by bees as butterflies floated by. As were headed back for cake, we also saw a bee-fly, it turned out not to be the usual Bombylius major or dark-edged bee-fly, but the much rarer Bombylius discolor  or dotted bee-fly, a new species for the reserve.

And so onto cake, cake is not a rarity at Blashford, less common than biscuits, but not rare. In this case it was to honour the departure of Katherine, an Apprentice Ranger with The New Forest National Park scheme run as part of the Our Past, Our Future Heritage Lottery Project. But it was not for this reason alone, but also to mark the last day of our own Volunteer Trainee, Emily, who also made the cakes, a valuable extra skill. Katherine had spent three months with us and Emily six, remarkable staying power by any standards. In fact Emily has volunteered to stay on, so is not going to be lost to the reserve yet. Katherine has moved on to spend a time with the Forestry Commission team locally.

After cake we headed out to look at the changes to the butterfly transect routes, it was a shame that it was still March, the transect counts don’t start until the 1st April and it is often hard to find many butterflies in the first few weeks. Today they were everywhere and altogether we saw seven species between us. There were lots of peacock, a few brimstone and at least 3 speckled wood, but also singles of comma, small tortoiseshell, red admiral and orange-tip.

A rather battered red admiral, probably one that has hibernated here and so is perhaps five or six months old.

Of the seven species five are ones that hibernate as adults, just the speckled wood and orange-tip will have emerged from pupae this spring. There is a small chance that the red admiral was a recent immigrant as they do also arrive from the south each spring, although usually later than this.

A different sort of life form is also in evidence on the reserve at present and I do mean a very different life form, slime mould. These are a bit of a favourite of mine and the one on a log towards the Ivy South hide is certainly living up to the name and is now oozing slime.

Locking up at the end of the day there was one last surprise, looking over Ibsley Water I saw a tern amongst the many black-headed gull, not as I expected an early common tern but a very fine sandwich tern, something of a rarity away from the coast.

30 Days Wild – Day 5

Continuing to catch-up. On day five I was back at work at Blashford Lakes and with the volunteers clearing around the main car park and path leading towards it. It was hot work and everyone was pleased when we called it a day and returned to the Centre for a drink and early lunch. As we were sitting at the picnic tables I noticed a large soldierfly nectaring on the hemlock water dropwort. It was a, ornate brigadier Odontomyia ornate, a species found in Hampshire only at Blashford Lakes and not seen for a couple of years.

After lunch I went for a walk around the reserve to see what might need doing after being away for the week. On the way I came across a brood of newly fledged robin.

As I was locking up at the end of the day I found one of my favourite organisms, a slime mould, growing on a log under trees near the Woodland hide.

Animal, Vegetable, Mineral? ( or Fungus?)

Those of a certain age may remember a TV programme , having (nearly) the same title as this posting, in which a panel of ‘experts’ were challenged to identify an object from a museum collection.   It sometimes feels like I’m on the panel when a visitor asks questions about something they have seen on the Reserve.  Fortunately, for the most part, I’m usually able to give a plausible (if not invariably correct) answer or direct them to somewhere or someone who can.  I don’t pretend to be an oracle and mis-identifications are always possible. (Thanks to those who pointed out that the long-tailed tit’s nest of last week is almost certainly that of a wren)

For the most part these questions concern the animal or vegetable (fauna and flora) on the reserve, not too many people are concerned with the minerals,  the extraction of which (sand and gravel) created what we have today.   One such question, from a conservation volunteer the other day, concerned a plant/fungus that he’d seen. From the description given both Jim and I concluded that he’d been looking at the young, emergent stage of the Horsetail or Marestail. Just like these on the reserve…

Horsetail - looking rather like an alien invader

Horsetail – looking rather like an alien invader

 I believe these are variously known as Common Horsetail, Giant Horsetail or Field Horsetail or sometimes Marestail – probably Equisetum arvense ( or perhaps you know different??).  More interesting than the name is that they are among the few remaining species of a genus which for more than 100 million years was the predominant type of land based plant life, some of which reached over 30 metres tall and eventually formed the coal measures.  So they certainly have ‘staying power’ which is probably why they are a persistent weed and are much un-loved by gardeners .

Talking of strange organisms, I’m sure many of you will have spotted strange excrescences, often white or yellow though sometimes pink, on logs and tree trunks in the woods. One such caught our eyes the other day and we went back to investigate, and take a picture of this rather magnificent slime mould   

Slime mould

Looking superficially like a fungal growth, I’d always bracketed them in with this group of organisms.  I did, however, know that the lump you see is really a sort of super ‘love-in’ where millions ( billions?) of single-celled organisms had grouped together to form this fruiting body.  They normally live thinly spread in the forest floor and at some signal migrate to one spot to swap DNA and reproduce via spores.  Quite how this is organised or triggered is still a bit of a mystery and the things themselves are, I believe, no longer classified as fungi – probably more like amoeba, feeding on algae and bacteria in the soil.   Also nearby was one of the resultant spore masses ….

Truly the more one sees the more mysterious are some of the things around us and just to round off this section I’ll include a picture of an outgrowth on the branches of a tree close to the small car-park near the entrance. I think they’re called ‘Witch’s Broom‘ and I believe they’re caused by insects or a virus – but perhaps someone out there knows better.

 On a more prosaic level the warblers reported last week have been augmented by at least two garden warblers, one of which was bold enough to perch out on the side of  a bush, giving reasonable views and a so-so image was possible at extreme range..

Although not a spectacular breeding site for wading birds we do get our fair share through the winter and it’s always nice to see some at this time of year. From the Tern Hide there were little ringed plover, redshank common sandpiper,  lapwing  and  a snipe has been seen.

As well as many black-headed gulls, tufted duck  and thirteen mute swan , Ibsley Water was hosting at least six common tern and little grebe nesting close by the Goosander Hide.   At the Woodland Hide a lone brambling (doesn;t he know it’s time to go?)  was still in evidence  and we still have some magnificent siskin on display.

A Chick Against the Odds and One Lost

The big news today was that as I scanned up Ibsley Water first thing this morning I saw a large redshank chick on the shore, they do not breed successfully very often so this was a great sight in a year that has been very difficult for waders. It was close to where the oystercatcher pair had their large youngster. I also noticed that there was still one of the adult oystercatchers nearby and it really went for a jackdaw that landed on the bank. Possibly the oystercatchers have still not come to terms with the loss of their chick and are still defending the area, if they continue it cannot but be good for the redshank chick.

Parking beside the Centre I noticed that there seem to be even more scorpionflies than before on the nettles beside the car park, they are always quite common but do seem exceptionally so this year.

At the Ivy North hide there were once again 2 grey squirrels on the tree to the right of the hide, mostly just grooming themselves in the morning sunshine.

I had a day of doing lots of small tasks and so was left with the vague feeling of not having got anything of any substance done, such is the way I suppose. At least the weather was good by recent standards, it even felt warm in the sunshine at lunchtime and the warmth brought out some insects and I got another picture of the large hoverfly Volucella pellucens.

I was briefly in the wet woodland just beside the Dockens Water in the afternoon where I came across what I think is yet another type of slime mold, although I am not certain as it is one I have never seen before, but that seems the most likely life form for it to be to my eyes. I will have to do a web search and see what I can find, unless of course someone reading this knows what it is. The picture is not great as it was in very deep shade and each was no more than about 7mm across at most.

slime mold, maybe

The common terns are still doing well although I see from the Ivy South logbook that one was taken by a large gull yesterday, although seems it dropped it under attack from the adult terns, unfortunately it was too small to fly and so got wet and drowned. The larger chicks often get lifted off the rafts when wing flapping but they are usually fine on our refuge rafts and usually fly well enough within a day to get back home. It is a perilous life as a small bird.

Stop press: It looks as though it is a slime mold and probably Lycogala epidendrum known as wolf’s milk slime mold.
