30 Days Wild – Day 4 Far and Wide

A very varied day for me today, I started with a farmland bird survey on the Hampshire chalk, almost on the Wiltshire border, then to Blashford working with the volunteers and finally a guided walk at Hurst Spit.

The farmland survey is always enjoyable as I get to see species that I otherwise rarely come across, in this case yellowhammer, corn bunting and grey partridge. It was a fine, if cloudy morning and it would have been completely enjoyable, if it had not been for getting soaked by the heavy dew as I pushed my way through waist-high goose-grass.

At Blashford we were working on the design of a new tern raft, I think we have more or less cracked it now! I also had to check the fences for the soon to arrive ponies and in doing so I found over 100 bee orchid! They grow in several places around the reserve but typically in small groups.

After a speedy lunch it was off to Hurst Spit to lead a guided walk. I walked the length of the shingle rather than going by ferry, this seemed a mistake as light rain started to fall. Fortunately the rain eased and then stopped allowing us to see at least some of the wildlife of the stabilised shingle at the end of the spit.

The stabilised shingle has a very distinctive flora with zonation from the high tide line back into the grassy areas via damper dips with areas of saltmarsh vegetation. We found a good few broomrape plants, seemingly parasitic on wild carrot, so I assume the coastal version of common broomrape.

Broomrapes are weird plants, they have no chlorophyll so cannot produce their own food, they live parasitically on other plants, tapping into their root systems. There are a number of species and some are very specific about the hosts they exploit, the common broomrape is one of the less fussy ones.

More typical shingle beach plants included some magnificent sea kale, huge, glaucous, leathery leaves and a great froth of white flowers.

We also saw lots of sea beet, and yellow-horned poppy.

As you can see it is a yellow flowered poppy, the “horn” is the seed pod, which can extend to 20cm or more, quite different from the typical, more spherical, seedhead of most other species of poppy.

It was not all plants though, we found three cream-spot tiger moths, a pale form of mullein wave and lots of the small coastal Pyralid moth Platytes cerussella. The area around the castle has lots of rock pipit, I am sure they have become more common  since I was last out there.

Walking back up the beach I came across a jellyfish in the tideline. I have not heard of many along the coast, but perhaps this is going to be a “jellyfish year”, one of those when they arrive in hundreds of thousands. I have always dreamt of seeing a leatherback turtle in such a year, as these huge reptiles will follow their jellyfish prey as far as our shores. Although reptiles, it seems they have the ability to regulate their body temperature, keeping it at around 26 degrees Celsius, allowing them to come into colder waters than their smaller cousins.

A Perfect Day

It was a glorious day at Blashford today, to my mind the perfect balance of sunshine and cool temperatures, the ideal autumn day for getting work done on the reserve. It was also a pretty good day for birds, although many of them have been with us for a while now.

When I first looked from Tern hide as I opened up I saw the two young little gull and thousands of house martin, low over the water, I estimated 3000 at least but they were everywhere low over the trees, lakes with others high in the sky. I could see no sign of the black tern or grey phalarope. A small wader on the gravel island way out near the middle of the lake caught my eye, there was something of a redshank about it but it was not one. This meant wood sandpiper was the most likely candidate and after a little while it was disturbed by a black-headed gull and made a short flight confirming the identification, our second of the autumn.

Later in the day it turned out the phalarope was still present and I got good views of it as I locked up. Other birds included both great white egret, at least one green sandpiper and reports of common sandpiper, I missed that, so did not get the “Sandpiper set”. Locking up the Ivy North hide I saw a pintail, the first for a few days.

I got no pictures of birds, or anything else today (working too hard, obviously!). However I will post a few pictures of recent notable records from the reserve, not great pictures mind you. The first is of a small Tortrix moth Olinida schumacherana, which seems to be the first record for the 10km square that includes the reserve.

The next is the Australian Pyralid moth that we first recorded last year as possibly new for Hampshire. In appears to have been introduced with the tree ferns that the caterpillars eat, although it now seems to be finding local ferns to its liking.

It was first found in the UK in Dorset in 2009.

I will end with a couple of pictures from my garden, two late butterflies bringing  a little colour to the end of their season.

30 Days Wild – Day 24 – Up on the Downs and Down by the Sea

We travelled up to Martin Down in the morning, specifically Kitts Grave the part of the reserve that belongs to the Wildlife Trust. This area of the reserve is a patchwork of chalk grassland and scrub, this type of diverse, herb rich habitat with lots of shelter is preferred by lots of insects, it offers lots of possibilities.

Plants like thistles and knapweeds are very good nectar sources used by lots of insects.

The scrub offers both shelter and an additional variety of flowers, bramble being very important and popular. I found the large hoverfly Volucella inflata feeding on a bramble flower.

As I was photographing it a male flew in and mating took place.

A few years ago when at Old Winchester Hill I found a rare bee-fly, the downland villa Villa cingulata , at the time it was only the second Hampshire record in recent times. It appears it has been spreading as I found several, easily five or more, egg-laying females at Kitts Grave, I am not sure if they are recorded from there before.

We saw a good range of butterflies including very recently emerged silver-washed fritillary and white admiral.

We retired home during the heat of the afternoon so I was briefly in the garden….

What’s in My Meadow Today?

One plant I was keen to establish was lady’s bedstraw, it has tiny yellow flowers unlike most of our bedstraws which have white flowers. It grows on dry chalk soils mainly but also turns up on dry sandy areas even in acid areas.

I seem to have only got one plant to establish but it is spreading to form quiet a significant patch.

Once the day started to cool we ventured down to the coast to Lepe Country Park. Years ago I established another meadow area at this site, although in this case it was from a deep ploughed cereal field, it is now a SINC (Site of Importance for Nature Conservation) for its wildflower community. Creating grasslands of real wildlife value is relatively easy and gets quick results, helping to redress the massive loss of these habitats. Planting trees is much more popular, despite the fact that it will probably take hundreds of years for them to achieve significant value for wildlife. As anyone who manages open habitat will know trees will colonise and grow quite happily without encouragement. In fact colonising trees are one of the threats to herb-rich grasslands.

However we were on the beach, looking at beach species. Stabilised sand and shingle has its own specialist plants, one of which is sea spurge.

Rather more attractive is the yellow-horned poppy.

The long pods which give this poppy its name can be seen in this shot.

It was getting late and there were lots of small moths flying about, in the end I managed to get a picture of one, it was a Pyralid moth, quite a common one found in a variety of dry habitats, called Homoeosoma sinuella.

Off the beach an adult gannet was flying about, quite a regular sight in The Solent these days.

An Alien has Landed

We run a moth trap at Blashford on most nights of the year, we record the species and numbers. Some species are regular and others we see only once every few years and just occasionally we get a new species. When I opened up the trap yesterday morning there was a moth I had never seen before, small but quite distinctive.

When  I looked in the book I could not find it, luckily the internet came to my rescue and I managed to identify it as a Pyralid moth, Musotima nitidalis a species native to Australia and New Zealand and first found in the UK in 2009 near Bournemouth.

So how did it get here? It appears it feeds on tree ferns and is likely to have been introduced with plants imported from Australia. It seems it will feed on some native fern species here, such as black spleenwort and bracken. Now it is here it will probably stay, perhaps as a scarce insect having little impact, or perhaps not. Once alien species establish the consequences will only become clear many years later and certainly there is nothing we can now do about this particular one but wait and see what happens.
