30 Days Wild – Day 23: Priorities

Finally a day when it was cool enough to get out on site with some machinery to get some of the paths trimmed. This is not the most glamorous of reserve management tasks but it has to be done. Managing a nature reserve is full of conflicting demands and dilemmas. No management is without impact and what is positive for one group of species will be negative for others. Trimming the paths often means cutting back nettles, as most will know these are the food plant of peacock and small tortoiseshell butterflies, so I try to avoid cutting the patches in full sun which they prefer and to do larger scale cutting only after they caterpillars have finished feeding.

The clearance of dense nettlebeds promotes patches of grassland and other herbage which is preferred by a wider range of species such as small skipper, which have just started to fly this year.

Over the years I have managed many different sites used for various purposes, ranging from nature reserves, long distance paths, picnic sites and Country Parks and these dilemmas occur at all of them. In truth all land management involves conflicting interests and all land is in multiple use. On a nature reserve wildlife will take precedence over most of the site, but access and safety will be paramount in some areas. I do believe that whatever the land use, it is wrong to deny the multiple interests, land management is about balancing interests not ignoring some entirely. Above all management should be about maintaining and enhancing the possibilities that are available for the future, good management is about increasing potential not applying a full stop.

Following Day 22’s horsefly picture I got another, this time of a male Hybomitra species in flight. This one is Hybomitra distinguenda and they fly very fast indeed, the picture was taken at 1/4000 sec and the wings are still in motion.

It is reputed that a species of this genus, albeit a rather large one from Southern Africa is the fastest flying insect having allegedly been clocked at 90 mph!

I have noted before how Blashford has many species that have come in from elsewhere, often due to the somewhat chequered industrial history. We have a number of coastal species including a very large population of annual beard grass, perhaps the largest in    the county, the natural habitat for it is poached upper saltmarsh, such a scan be found at Farlington Marshes.

30 Days Wild – Day 14: Getting Brown

A hot day and at this time of year one when you need to take care in the full sun. I was in the office for much of the morning, which was at least cooler. At lunchtime I went outside, hoping to see some hoverflies and soldierflies on the hemlock water-dropwort, but all I saw was bees. I think it was too hot for many insects, on these kind of days they often sit out the hottest part of the day in the shade and can be found clinging to the underside of leaves.

A number of people have commented on the lack of butterflies in recent days, it is true there are not a lot, but this is not that unusual at  this time of year. The spring species have mostly finished and the high summer species are just starting, the “gap” is often bridged by lots of white butterflies, but this year they have been quiet scarce. At Blashford the mid-summer butterflies are the browns and the meadow brown are just starting to appear in numbers now. They do not bask with wings open very much once the day has warmed, up so it was no surprise that they were all sitting with wings closed today.

Meadow brown has just one generation a year and they will fly from now until early September. Some species, like small tortoiseshell and comma have two generations, with the second over-wintering as an adult hidden away out of the worst of the frost. Another of the browns, the speckled wood has three overlapping generations so can be seen from late March to early November, it can also over-winter as ether a caterpillar or a pupa.

In other news, I saw the larger of the lapwing chicks today from tern hide and it must be getting close to fledging now, as is the one remaining oystercatcher chick. The three smaller lapwing chicks seem to have been reduced to two, but they at still growing well. Out on the rafts most of the common tern eggs have now hatched and generally they seem to be in broods of three, with lots of small fish being brought in, so they are growing fast. Today many of the chicks were using the shelters to get out of the strong sunshine, over-heating can be a real problem for small chicks, so shade is important.

April Catch-up

April is flying by and we’ve been busy! We’re sorry for the rather long gap between this and the last blog, but hopefully this one explains a little of what we’ve been up to and what’s currently out and about on the reserve.

The sunshine brought plenty of visitors to our local craft event, who enjoyed the excellent refreshments provided by Nigel and Christine’s pop-up café (which will return in November) along with basket making, hurdle making and wood turning demonstrations and the chance to have a go at making bird feeders from willow.

This was swiftly followed by Wildlife Tots, who got into the spirit of Spring by making excellent nests for our cuddly birds.

We then entertained a holiday club visiting from London with den building and fire lighting activities, followed by a night walk. We’ve welcomed new six-month volunteer placement Harry, who is with us now until September and thrown him in at the deep end with a group of beavers who were here to enjoy a river dip. Luckily that didn’t put him off and Emily and the other volunteers have been busy showing him the ropes.

This week we’ve had two wet Wild Days Out, pond and river dipping in search of newts, fish and other monsters, rescuing ducks, floating boats, building dams and enjoying a balloon free water fight. Our most monstrous find was this awesome Great Diving Beetle Larva, which tried to devour anything in its sight:

Our volunteers have been super busy, with the warmer weather bringing with it the start of our butterfly transects and reptile surveys. The butterfly transects have had an excellent start, with Peacock, Orange Tip, Brimstone, Speckled Wood, Comma and Small White all recorded and Holly Blue, Green Veined White and Small Tortoiseshell also seen around. They have already recorded more than they did in the whole of April last year, so fingers crossed numbers will continue to be good!

Grass snakes and adders have started to venture into areas accessible to visitors so if the cloud disappears and the temperature warms up again keep your eyes peeled! Two grass snakes were seen recently from Ivy South hide, but out of the window at the far end rather than their usual basking spot on the log outside the front; whilst the grass verges too and from Lapwing hide are usually good places to try for a basking adder.

In bird news, Lapwing, Common sandpiper, Redshank and Little ringed plover have all been showing nicely in front of Tern Hide, along with the Black headed gulls which are getting more and more vocal! An osprey reportedly flew over the reserve on Wednesday and a Common tern was also seen on Wednesday from Tern Hide.

A Great spotted woodpecker has been busy excavating a hole in a tree trunk near Ivy Lake and best viewed from the far right hand window in Ivy North hide. Brambling were also still being spotted from the Woodland Hide this week, looking very smart as they develop their summer plumage and our first fledglings have been seen too – Robin and Dunnock – so keep an eye out for parent birds feeding their young.

Thanks to Lyn Miller and Steve Michelle for also sending in some great photos from recent visits to the reserve:

Finally thank you to everyone who’s popped in to tell us what they’ve seen, Jim and I have unfortunately been slightly office bound when not out and about leading events and group visits, so it’s great to know what’s going on out on the reserve!

We will try not to leave such a long gap between this and next blog, Bob’s back from leave soon so fingers crossed!

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 27

Up and out early today to do my final breeding bird survey of the year, in fact not quite as early as I had hoped as it was rather drizzly at dawn, but still in the field by 05:40. I am surveying a site about 40 minutes from home so there is always a risk that conditions are okay at home but not at the site.  As it is now quite late in the season a lot of birds have stopped singing and some have completely finished nesting and are wandering around in flocks. In this regard the rather wet conditions of late are an advantage as this enables many resident species to have an extra brood, species like song thrush and blackbird, will give up in June in a dry season but can often have an extra brood if worms are still easy to come by in a wet season.

I did have quite a few singing thrushes and also a lot of wren and the summer visitors are still mostly singing so chiffchaff and blackcap were in good numbers. I also had several young birds, some being fed by their parents, confirming breeding. The survey involves mapping the location of every bird seen or heard on eight to twelve visits. This can then be analysed to give a fair estimate of the number of territories of each species present. All I have to do now is transfer all the data to species maps and work out how many territories of each species I have found, it could take a while!

For almost the whole of my four hours on site it was grey with low cloud, but just as I finished the sun came out and with it lots of insects. I saw meadow brown, marbled white, large skipper and small tortoiseshell in just a couple of minutes.

Almost next to the butterfly on the same bramble there was a very smart longhorn beetle, with a very long-winded name, it is the golden-bloomed grey longhorn beetle Agapanthia villosoviridescens.

My afternoon was spent in a meeting at County Hall, Chichester, a pretty wildlife free zone, but as I left the building it was great to hear the cries of the peregrine on the cathedral, probably the young ones after food from their parents. It is amazing to think that about forty years ago these birds were restricted to western cliffs and that they were plagued by the twin ills of egg collectors and pesticides to the point where it seemed we might lose them altogether.

 

30 Days Wild – Day 18

When I checked my back garden moth trap in the morning I found the catch included a mottled beauty, a very common moth, but still worth a second, or third look.

I had a day in the garden, or perhaps more accurately gardens. I started in my own with the moths and then visited a rather larger one. As well as the plants there were quite a few insects about, despite the overcast conditions. I saw my first summer brood small tortoiseshell.

There were also quite a few hoverflies, although this summer does seem to have been very poor for these insects in general. One I did find was a very smart Volucella bombylans, one of the better bumblebee mimics.

Back at home in the late afternoon I went to check out my “Bee hotel”, actually just a large block of wood with lots of holes of different sizes drilled into it. Many of the holes were occupied, some sealed up and some with occupiers at home.

First Flowering

I was acting as substitute Jim today as he is on leave, it made a change to be on the reserve on a Saturday and a very pleasant one, in the fine spring sunshine. After a morning spent tying up various loose ends from the year end, I took the chance to get out tin the sun after lunch. I wanted to check out a few of the projects we have done over the years and see how they have worked. First I went to an area we cleared of rhododendron some five years ago, it had been one of the few areas not dug for gravel and still had a few large, old hazel stools growing up through it. We cleared the rhododendron and planted  a few hazel in their place. The ground flora had all been killed off by decades of deep shade from the rhododendron, so we decided to try collecting some wild daffodil seed from near the Woodland hide and spreading it on the bare ground, to see if we could establish some new plants. The seedlings came up and today I found the first flower!first daffodil

Wild daffodil are a feature of the reserve, or at least the areas that were not destroyed by gravel extraction, so re-establishing them to places they would once have been and removing planted garden daffodils is a thing we have been to do for some time.

I then went to the western side of Ellingham Lake to look at the hedge we laid last winter. It has suffered somewhat from being nibbled by rabbits, but is not looking too bad on the whole.hedge

The sunshine had brought out lots of butterflies, I saw good numbers of brimstone, a few peacock and a single small tortoiseshell.small tortoiseshell

Most of the butterflies were nectaring, as this small tortoiseshell was, on ground ivy, one of the best sources of food for butterflies and bees at this time of year.ground ivy

I also found a fine grass snake enjoying the sunshine, it was on very open ground so rather than slip off to cover it reared up in threat and then froze, allowing me to get some shots.grass snake

With a little effort I managed to creep really close and get some headshots, when I did it became apparent that it had some sort of damage around the upper jaw, it looks quite nasty, but the snake seemed to be in otherwise good shape.snake head

There had evidently been some arrival of migrants overnight, with a couple of willow warbler singing near the main gate as I opened up and there were noticeably more chiffchaff and blackcap. The highlight though, was a male wheatear on the lichen heath near Ivy North hide.

As I ate my lunch I watched a pair of long-tailed tit collecting spider’s web for their nest from under the eaves of the Education Centre and the resident pair of robin were courtship feeding on the picnic tables.

Closing up the Tern hide a sudden commotion flushed all the shoveler from the south-east part of Ibsley Water out into the centre of the lake, allowing me to get a good count, the total was 283, pretty good for April. There was little else to report, although the Slavonian grebe was still there somewhere apparently, although I failed to see it myself.
