Meet at the Nadder Centre car park on Sat 3rd June at 10.30am or approximately 1 hour 15 minutes later at the Westhay Moor Reserve BA6 9TX. The car park is at OS ST 456 437, just north of the junction between Westhay Moor Drove and Dagg’s Lane Drove, between the villages of Westhay and Godney.
Distance, Difficulty and Footwear: Approximately 5 km/3 miles on flat gravel paths which may be a bit muddy if there has been recent rain. Good stout shoes should suffice rather than wellingtons. Bring a packed lunch and refreshments. This Field Trip has limited numbers. There may still be places if you've not yet signed up and want to come. Equally please let us know if you're on the list, but can no longer make the date. We are now using the email address tisburynathist@gmail.com for organising lists for events, so please contact us there. Congratulations to our committee member Debbie Carter, who has been shortlisted as a finalist in the Green category for BBC Radio Wiltshire’s Make a Difference Awards.
As most of our members are aware, Debbie has been a very active and essential committee member for many years, in addition to other nature-related causes in Tisbury and surrounding area she’s dedicated a lot of time, effort and passion. Woodlands Alive organiser, parish council’s tree warden, WWT’s nature reserve warden, water vole surveyor, dormice surveyor… Debbie was conducting a botanical survey near the community field (which she was instrumental in obtaining for the enjoyment of all the residents of Tisbury!) when she received the call from BBC to let her know about her nomination! So we are very pleased to hear Debbie has been shortlisted. They’ve had more than 200 nominations in total across the eight categories, with finalists being shortlisted by a panel of four, based on anonymous nomination letters. There will be an award ceremony on Saturday 23rd September, where they will be announcing the overall winner for each category. In the meantime, you will be able to hear Debbie’s story, as well as that of other finalists, on interviews BBC Radio Wiltshire will be conducting over the summer. We wish Debbie all the best for this award and thank her for all she does for nature and all of us who value nature. by Inés López-Dóriga On 20th April we had our final evening talk given by Simon Martyn with photos provided by his wife Mandy.
Simon was the European Director of Earthwatch, an International NGO which started out in Boston, USA over 50 years ago but is now worldwide with offices in Australia, UK, India and Japan. Earthwatch sets up projects both for Wildlife and Archaeology with scientists running the projects, helped by a workforce of volunteers. They carry out research and provide essential statistics to establish conservation schemes for threatened species or habitats as they work alongside local people. The talk was ‘Glimpses of Wildlife Behaviour’ and was divided into sections. Firstly, we were shown various habitats and their wildlife such as the much depleted herds of bison in Yellowstone Park, the plains of Africa with the wildebeests and various antelopes, plus the harsh, freezing environment of the Arctic. Secondly, the emphasis was on territory and, especially during the breeding season. Male lions guarding their prides and fighting off the opposition were illustrated. We saw how Roe and Red deer will also become very aggressive fighting off other bucks and male tigers will kill another male tiger’s cubs in order to mate with the female and pass on his genes. We saw a grisly photo of this. (NB. Badgers also do this, as I can witness). The effects of climate change were visible in the photos of droughts in Africa, drying up the rivers and water holes, causing many animals to die and causing mayhem at the water points with competing animals. Thirdly, Simon showed us photos of how many species co-operate with others for the benefit of both. For instance, egrets and finches will hitch rides on buffaloes to eat the ticks and crocodiles will stir up the water and expose the fish for the storks on their backs. In India the Langhur monkeys work as lookouts for the Spotted deer when a tiger is about, shrieking in terror. Finally, we were treated to humorous photos of various animals and birds in compromising and amusing positions including a harassed mother Brown bear trying to control her three naughty cubs. One was up a tree, another near the river and the third heading up the mountain. It was an entertaining and illuminating evening with superb photography and a nice change from all things local. by Debbie Carter Rabbits are renowned as prolific breeders. Females are fertile at 3-8 months old and have a gestation period of around a month. They give birth to a litter of 4-12 kits and may be ready to mate again the next day. This, combined with the fact that they can breed throughout the year, means that in the right conditions, populations can grow rapidly, hence the expression ‘breeding like rabbits’. This proved disastrous when 13 rabbits were introduced into Australia in the 19th century where, in the absence of suitable predators, they spread across the continent in 50 years, devastating crops and the natural environment alike. Rabbits, originally native to Iberia, spread around the continent in Antiquity and were introduced into the British Isles first by the Romans and then the Normans, as a source of meat and fur. In places, artificially built warrens were looked after by warreners, so landowners had a constant supply. Warren and coney (the old name for rabbits) crop up in numerous place names around the country as a result. Of course, rabbits are perfectly capable of making their own burrows, using their sharp claws to dig into the ground, often under sheltering scrub. From there they will venture out to feed. They have virtually 360% vision, as befits a prey species, and are always on the lookout for threats. Their white tail, or scut, provides a flashing warning sign to others when running for cover. A sizeable colony can have quite an impact on the grassland in vicinity of the burrows, creating a closely-cropped turf, benefiting mining bees and wasps as well as herbs that cannot compete in a longer sward. Rabbits provide food for a number of species that prey upon them, including stoats, buzzards, polecats and foxes. When we moved to Tisbury, we were struck by the absence of rabbits in the surrounding countryside. Although rabbit numbers have been increasing each spring, populations keep getting knocked back by autumn, perhaps due to diseases: myxomatosis and viral haemorrhagic disease. When the former was first introduced to this country in the 1950s, it wiped out most of the population, since then its impact has reduced but stays active. What impact the dearth of rabbits in this area has on the breeding success of its predators? I am afraid that for the immediate future, the rabbits we are most likely to see locally are the Easter Bunnies on Easter cards (how rabbits became associated with this is an entirely different question!). P.S. In Weymouth we were encouraged to use the term bunny in deference to Portland superstitions about use of the R word. I hope any readers from Portland have not been too traumatised by this article. by Andrew Graham [editor - with apologies for the late upload this month] Now is the time when we think of Mad March Hares: seeing the animals chasing around in a field, jumping over each other and “boxing”. This behaviour, which is actually not restricted to this month, is all about courtship or partly, the refusal of courtship. Male hares – bucks - are more numerous, so females – does - that are unreceptive to amorous mates may vigorously fight them off. A female leading a potential mate on a chase across a field may be testing his speed so she can select the fastest male to father her offspring. She can produce three or four broods of young a year. These are called leverets and are born fully furred and ready to run. They will keep themselves hidden during the day returning to the doe at sunset for a daily feed and are weaned in a month.
Brown hares are preyed upon by foxes, stoats and buzzards but also subject to poaching and illegal hare coursing. They do not burrow like rabbits but live above ground and so rely on their speed to evade predators and escape to cover. They are the fastest British land mammal and can reach 40 mph at full pelt. Its long back legs provide this speed and results in a distinctive loping gait very different to that of the rabbit which is about half the size and weight. Rabbits have black eyes, very different to those of the hare which are a wonderful amber. Its ears are much longer than the rabbit with distinct black tips. Their fur is golden brown with a white belly. The other hare seen in the mainland UK is the mountain or blue hare which is mainly found on Scottish heather moorlands. The best time to see Hares is early or late in the day. During the day they may lie up in a depression on the ground called a form. They will sit tight when approached before hurtling off at the last moment, often stopping after a while to look back then loping off at a more sedate pace. If you are lucky enough to spot them before they speed off, you can have a staring match and see how inconspicuous they make themselves, hunkered down with their ears lying along their back. You are most likely to see them in arable farmland and wide-open grasslands, woodland edges and hedgerows – places which provide shelter. So they benefit from a mixed agricultural landscape rather than one devoted to a single crop. The downs along the Shaston Ridge and the arable fields adjacent are a favourite place to see them and they can be seen in vicinity of Tisbury although dogs running off leads scare them away before most people see them. Unfortunately, hare’s numbers are estimated to have declined by 80% in the last 100 years. Some are now suffering from rabbit haemorrhagic disease which further threatens them. We are fortunate to still have these beautiful animals in the countryside around us. by Andrew Graham This cosy nest was photographed by Andrew Graham and shown to Inés and Debbie who concluded it belonged to a Wood mouse. Having the ruler for scale and its location in a wood pile, helped to identify the animal who'd made it. We're always happy to assist with any identification queries, so if you want to use the contact form first of all, we'll send you the email address for submission.
Our AGM will start at 7.00pm for a brief run through of the minutes of last year’s meeting and the 2022 accounts. We urge as many members as possible to come along. The hall should be open half an hour before we start, so this year you can even enjoy the proceedings with a glass of wine in hand. ![]() The talk will start at 7:30pm and we shall hear from Sarah Barnsley on 'Why hedgerows matter'. Sarah is Hedgerow Officer for the People’s Trust for Endangered Species, and a huge hedgerow enthusiast, working to promote these humble countryside heroes. Hedgerows form a key component of our natural heritage and provide many vital ecosystem services and functions. They connect up our countryside and provide essential food and shelter for much of our wildlife. From nesting birds to hibernating hedgehogs, well-managed hedges can provide abundant resources for animals, birds and all manner of insects. Yet, to maintain a healthy hedgerow network into the future, we need to manage hedgerows according to their natural lifecycle. Bats can live up to 30 years. After spending the winter hibernating, bats will now be fully active and feeding. At first light or dusk, on warm dry days, is the best time to look out for them. Some hunt high in the sky while others swoop low over water. The females, which will have been pregnant since the autumn mating season, will set up nursery colonies in May and then give birth to a single pup, usually in June. These pups are very small and, as bats are mammals, will be suckled until they learn to fly and hunt insects for themselves by August.
Although different species frequent different areas, a landscape generally favourable to bats includes varied sites to roost in, such as old buildings, caves, and hollow trees; hedgerows along which to commute to and from foraging areas, woods, copses, lakes, and ponds. This seems to be a rather good description of the Nadder Valley, and it seems to suit bats. Last year, the South Wiltshire Greater Horseshoe Bat Project carried out a programme of acoustic surveys using bat detectors across 40 locations in the Nadder Valley. Of the 18 bat species found in the UK, they detected 13 species, both common and rare. At the same time, a small stone mine was monitored, and this confirmed that it is used by several rarer bats, including the greater horseshoe bat. These data contribute significantly to the knowledge of bats in the area. Unfortunately, bat populations declined severely during the last century. In common with most bat species, those found in the UK feed on insects. Given that even a single tiny pipistrelle bat can eat more than 3000 insects in a night, the well documented fall in insect numbers in our countryside is likely to be contributing to this decline. If they cannot get sufficient food in autumn, when they are building up fat reserves to get them through the torpor and hibernation of winter, they will perish. They are also vulnerable to a range of other factors such as loss and fragmentation of habitat, destruction of roosts, and predation. Bats and their roosts are protected by law, but are still under threat from building and development work that affect the old buildings and trees where they roost or set up maternity colonies. by Andrew Graham Peter Shallcross will be leading a river walk from Wylye to Fisherton de la Mere this coming Thursday, starting at 7pm. The distance along the footpath beside the river is around a mile each way, pretty flat and sound along its length, so not particularly onerous.
Members don't need to register but if you'd like to come as a guest please let us know via the contact form. To share car spaces and conserve fuel, meet at the Nadder Centre car park at 6:30PM or alternatively make your own way to Wylye for 7:00PM. The rendezvous point is a layby immediately after the river bridge on the main road north of Wylye, after passing the Bell pub on your right: see https://goo.gl/maps/9jAP7xYZqvhWn3Qp6 And you may care to bring with you a picnic to enjoy in the churchyard before heading home again. Gareth Harris of the Wiltshire Bat Group has sent us an update on The South Wiltshire Greater Horseshoe Bat Project which was launched in October 2020. As Gareth remarks in his update, “a considerable volume of work has been achieved” including the enhancement of roosting sites, hibernation counts and large-scale bat detector & dung beetle surveys.
Further information from Gareth “During 2021, over 50 locations were surveyed for bats using static bat detectors, recording around 700,000 sound files, over 376 nights of survey, generating records of 13 species of bat. Notably this included many new records of foraging Greater horseshoe bat, as well as other rarer species of bat such as Barbastelle bat, Leisler’s bat and Lesser horseshoe. The map below illustrates the spread of locations surveyed in 2021, and then specifically which of these recorded Greater horseshoe bat. Given the importance of the Nadder valley, hosting Chilmark Quarries SSSI for example, it is unsurprising to see this area recorded such a high activity of Greater horseshoe bat. The project also initiated landscape-scale surveys for dung beetles; dung beetles are a major food source for adult and juvenile Greater horseshoe bats throughout the year (including during the winter months). Surveys were undertaken close to roosting sites of greater horseshoes as well as the wider landscape. This work feeds into partnership working with local farmers, promoting the importance of dung beetles in soil health, carbon sequestration, and also in managing livestock endoparasites. There is growing evidence that a diverse dung beetle assemblage may reduce the requirement to use livestock worming products which decimate the wider soil invertebrate community, including dung beetles.” The Wiltshire Bat Group will be releasing further updates on their website in due course, so you’ll be able to find out more about the impacts of their bat and dung beetle surveys there. |
