La Réserve Naturelle du Pinail


Human activity has always changed the environment and in this article in 2014 I took a quick look at an extraordinary area that since 1980 has been the first and only State Nature Reserve in the Vienne departement of France, La Réserve Naturelle du Pinail which is located in the commune of Vouneuil-sur-Vienne, (86210). The Reserve is 30 km north-east from Poitiers and 15 km south from Chatellerault where it sits high on the plains between the river valleys of the Vienne and the Clain, at the north of the state owned Moulière forest. The reserve is well worth a visit, especially for people with an interest in Odonata, (Dragonflies and Damselflies) CONTINIUED HERE.

Thistles and Dandelions

Very few people are neutral when it comes to certain native plants, (or weeds as they are often known as), especially the more robust and common types such as Dandelions and Thistles and I certainly don’t want them in my vegetable or flower beds. However they along with a few other native plants form the most important natural source of nutrition for many of our butterflies, bees, hoverflies and other flying insects growing as they do in a vast range of different habitats and are worth a second thought before trying to chop them down or poison them at every opportunity as is sadly the case in an increasingly tidy and over managed landscape here in France.

Of course I don’t expect for one minute that anyone will suddenly think “Oh, I must grow some thistles or sow a dandelion patch” especially if they live in an urban environment or in very close proximity to their neighbours but I would like to encourage anyone with some land or with larger gardens to leave a few thistles and to perhaps let dandelions flower for a while just to see for themselves just how beneficial they are and how many different creatures use them.  



I also leave the seed heads to stand on all the plants in our fields which provide food for seed eating insects and birds throughout the autumn and winter months as well as providing a depth of ground cover for the birds that require it.




With this in mind I've compiled a simple web page with some photos of thistles and insects that have been mainly taken on our land.     CLICK HERE

Crickets and a few selected photos and other oddments from June / July

A small selection of bits and pieces from the last few weeks with a few photos some of which I’m quite pleased with especially the Libelloides longicornis which I've waited years for, massive thanks to Samuel Ducept of Vienne Nature for making his hand available. 


Click on pictures to enlarge.


Libelloides longicornis is found in South west Europe and frequents sunny open habitats where they hunt flies and other small insects by patrolling at a height of about 2 to 3 metres.


Now a word in your ear about being a bit careful when translating French names to English for creatures which isn't always that simple especially when the dictionaries have it wrong in some cases. A classic example is the French word Sauterelle which will translate to Grasshopper in most major dictionaries when in fact it should translate to Bush cricket.

This may help to avoid confusion.

Sauterelle = Bush cricket – long antennae
Criquet = Grass hopper – short antennae
Grillon = Cricket – long antennae apart from the Mole cricket, Gryllotalpa gryllotalpa which has short antennae.

I’ve seen five different Crickets seen in the last month to share here including a juvenile Mole Cricket discovered under a large stone by a lake. Turning rocks and stones will often produce interesting results exposing creatures that are taking shelter.
  
Some people get confused and think that the Field Cricket is the Mole Cricket because the male Field Cricket uses an angled hole in the ground to hide in and try to attract females to it, however the Mole Cricket actually spends most of its life underground where it tunnels with its powerful front legs that are adapted in a similar fashion to a mole. In this photo they are tucked in by its head.

Mole Cricket – Courtilière - Gryllotalpa gryllotalpa.  Wet or moisture retentive fields and meadows, edges of ponds, lakes, rivers and similar water courses. Up to 5cm


Grillon bordelais (Tartarogryllus burdigalensis) Bordeaux Cricket. Open grassy scrub, cultivated fields and similar habitats. Up to 1.5cm


Grillon des bois (Nemobius sylvestris) Wood Cricket. In all types of woodland and bordering scrub and grassland. Up to 1.25cm


Grillon des marais (Pteronemobius Heydenii) Marsh Cricket.  Along the edges of and in close proximity to lakes, ponds, rivers and similar water courses. Very small Cricket no more than 1cm.


Grillon champêtre (Gryllus campestris) Field Cricket. Almost anywhere but especially different types of grassland. Up to 2.75cm





Moving on to another interesting species that I was shown, a small group of Martagon Lilies in some ancient woodland near to Lussac les Chateaux in Vienne. Although this isn’t a rare species in France they are normally found in mountainous regions, Alpes, Pyrenees, Jura and the Massif Central but here hidden away in these woodlands are some very small pockets following the retreat of the last glaciation.  Remarkably, (or maybe not), they had Scarlet Lily beetles, Lilioceris lilii, on them and had presumably been existing together for many years.



Three butterflies that might be of interest for UK residents as they aren't to be found there. Otherwise it’s been a very poor year for butterflies around here so far other than for the commonest of species and very few of some of them. On the bright side there has been an apparent increase in the number of Small Tortoiseshells, Aglais urticae, a species that has become rare in the region in recent years. I saw four individuals earlier this year here!

Mallow skipper Carcharodus alceae (L'Hespérie).


Weavers fritillary  Clossiana dia (La Petite violette)


 Ilex hairstreak  Satyrium ilicis (Le Thécla de l'yeuse)
  


On the bee front it’s been mixed to say the least of it. The Sweet Chestnut started to flower and for a few days it was hot and the bees were working hard, then as in recent years it took a turn for the worse with cold and rain on and off finally culminating in half the trees with spoiled flowers before they even opened. The first of the Sunflowers started to open about a week ago and right now it’s hot and sunny – I hope it lasts, the next four or five weeks will determine the honey yield.

Had a call to a small colony the other week that was built behind shutters in a doorway which took about 30 minutes to remove and put in a ruchette, I wish they were all that simple and then yesterday I had a really, really small swarm in my apiary which I’ve popped in a Warré and today they appear to be behaving like bees with a purpose! If they do have a Queen they will need some syrup to get them anywhere near strength for winter.


Earthnut pea, Lathyrus tuberosus, is an amazing and little known plant, a real all rounder being very attractive with a super perfume and importantly honey bees love it  A perennial that once introduced and established will form dense clumps and can be used to climb fences or through bushes.
  


I can’t help but admire, if that’s the right word, how the Crab Spiders have developed over time with their hosts, the plants and their flowers and their prey which visits the flowers, mainly it seems to be bees, butterflies and hoverflies that succumb to their fangs.

Off to check the bees now,

In our fields recently.

It’s fair to say that our fields aren't the most exciting habitat in the region although they probably are the most species rich as a whole for the immediate area albeit most of the species are common, but then common doesn't mean there aren't increasingly reduced numbers at a local level – it all adds up and ours is probably the only decent size bit of proper grassland for many kilometres, everything else is cultivated or so called improved pasture which is really only one step up from a wheat field in terms of species usefulness.

Anyway this isn't about the surrounding area but just a small selection from some idle wandering here and there in our own fields recently with the camera just taking photos of anything that caught my eye and hopefully draw a little attention to the simple plants that can make all the difference.

Starting with a couple of plants that once introduced to grassland will soon establish and sort themselves out, Crown Vetch and Birds Foot Trefoil. These two along with other vetches and tares provide food for a large number of species in both the adult and larval stages. In the last week or so I have seen 6 Spot Burnet moth, (Zygaena filipendulae), 5 Spot Burnet moth, (Zygaena trifolii), Reverdin's Blue butterfly (Plebejus argyrognomon), and large numbers of Burnet Companion moth, (Euclidia glyphica), so called rather obviously because it is invariably found where there are Burnet moths.

Four different orchids, Greater Butterfly, Loose Flowered, Pyramidal and Bee have all been flowering in the grasses and although they are native species and quite pretty I’m never sure what other value they have. Contrary to popular belief bees and other insects rarely visit most species of French wild orchid and as far as I know they aren't used as a food plant by anything. Having said that I did manage to catch a honey bee on a Pyramidal Orchid in a time of desperation when there was little else available to forage although it quickly flew on and ignored the others.






Marbled White butterflies are out and about in their hundreds, uncut grassland is their number one habitat for successful breeding.



Meadow Clary and Rampion Bellflower are great providers of nectar for insects as is Ragwort; the latter is more or less the only plant that is used by the Cinnabar moth for its caterpillars. We have quite a large number of Ragwort plants and although it has a somewhat bad press from some quarters it's really a rather useful plant provided it doesn't form part of cut hay for animals. The Roe Deer do their usual trick of biting off the tops and then presumably don't eat them - let's face it most animals don't eat things that are bad for them if they have evolved alongside them. 






The Apiaceae (or Umbelliferae), which form the celery, carrot and parsley family are wonderful insect plants, many are the wild plants that have been selectively breed over time to produce the cultivated varieties we grow and eat or use in cooking and indeed many of the wild species are edible although great care needs to be shown with identification as some such as Hemlock are highly toxic and many can produce reactions on tender or sensitive skin when brushed against but of course this no reason not to have them on your land. With the right soil it's possible to have one species or another flowering from April until September. A couple of examples here, more later when I post something about the wider subject of pollinators.




None of these species, (and many, many more), were present here when we first purchased the property which shows a little of what can be achieved with a bit of wilding.

Winter work 2013 - 2014

Perhaps understandably many people I meet often have the strange idea that managing land for wildlife means doing nothing, just letting everything go and take its “natural” course. If only that was the case, which I suppose it could be if the objective was to allow everything to revert to woodland, but even there it would require managing in one form or another to maximise its benefits. Anyway there’s no shortage of trees in the general sense here – yet !!!

Where we live certain habitats have all but disappeared in recent years, the final nail in the coffin was the removal in 2008 of the requirement to put 10% of land out of production, a process known in English as “Set Aside”, (to leave fallow / en jachère). This has lead to just about every last piece of land that isn’t woodland and that can be used for cereals to be ploughed up as mentioned elsewhere. Even in 1996 when we purchased our house and three hectares things were bad enough leaving little choice for us but to at least try and create a little oasis of decent habitat and manage the bulk of it, (about 80%), as “rough meadow or natural grassland”. The remaining 20% was already trees or woodland which I have also been slowly changing aided by a couple of serious storms that helped with the thinning process.

This winter I’m trying to catch up on one particular section that has been neglected for a couple of years more than it should have been with a danger of some species being temporarily lost due to brambles, scrub and small trees swamping them.  




In particular there are quite a large number of Greater Butterfly Orchids that started to show after we had been here about 8 or 9 years on this part of the land and it’s a tricky balancing act with them. It’s quite strange that I haven’t found this Orchid anywhere else remotely near our property or the Loose Flowered Orchids that we have a couple of although they must have been around here historically. Bee, Pyramidal and Lizard Orchids that have also popped up on the land are to be seen locally in the area so not a surprise, but it does show what can happen even on land that has been intensively cultivated given a little time.




It’s also an area with a few different species of violet that need to be given a bit of light and space, all common species but important for the Fritillary butterflies we have here that use them - Weavers, Queen of Spain and Silver washed, all fairly common species as well but starting to struggle with the steady reduction of available plants. Many of the violet plants that do manage to survive are often by the roadsides that are constantly cut to the ground giving little chance for any eggs or caterpillars.





Masses of Lung wort, Pulmonaria, flourishes in this section as well and again although a common plant it’s just so important as a long flowering early insect food source, especially for Bumble bees when there is little else around in February. 



More of this later, Chris

Mistletoe everywhere

France is quite well known in Europe for its Mistletoe and exports large quantities every year to the UK for the Christmas celebrations, something it has been doing for well over 100 years.  Although its abundance here varies greatly from region to region where it does grow it really grows with a vengeance especially on poplar trees that have grown in the wetlands of France since before the second world war. However they have been planted in increasingly large numbers in recent years as a fast growing crop making use of boggy areas and places that are regularly inundated such as riversides. They are almost exclusively hybrids and there have been trials in France with Genetically Modified varieties, (GM or OGM). 

Environmentally these poplar plantations are a catastrophe destroying wetland habitat on a vast scale with a corresponding loss of species BUT money talks everywhere and nowhere more than in France where leaving a piece of land without it producing something is a cardinal sin.

I suppose, (grudgingly), I would have to concede that they have been a bonus for Golden Oriole that are particularly attracted to them to make their high nests but this doesn't even begin to compensate for the harm done. 



Mistletoe is a parasitic or semi parasitic plant with separate female plants that bear the fruits or berries and male plants that don't. It depends entirely on birds for propagation and I always thought of the Mistle thrush in this respect, never questioned it really, especially with the name association and the fact that it's one of the birds that will eat the seeds. However it seems in reality that the Blackcap is the best bird in this respect.



I found this really good web site all about Mistletoe so rather than crib from it, here's the link.
