January Newsletter, 2016
New Habitat for threatened butterfly
In the spring of 2015, Nigel Heptinstall discovered a colony of Dingy Skipper at an old car park on the shores of Thruscross Reservoir. Unfortunately a large amount of aggregate, destined for footpath repairs, was deposited on part of the site which the butterflies favoured. Following discussions with Yorkshire Water and the footpath contractor, steps have been taken to avoid further disturbance of the existing areas and a plan has been devised to use some of the aggregate to create two new areas of habitat, to help conserve this threatened butterfly. The Wharfedale Naturalists would like to thank Paul Millard, Yorkshire Water and Fountains Forestry in helping make this happen.
Jeff Davitt has kindly scanned two commemorative publications marking 40 and 50 years of the Society:
Nature Station’s January Newsletter
You may have heard reports of Daffodils out in December and Nature Station’s January Newsletter looks at how our wildlife copes with mild winters such as these. They point out more insects are able to survive the winter which can lead to larger numbers in the spring providing more food for birds and other animals. I was surprised to learn Frog tadpoles can remain in ponds throughout these months and continue their development in the spring, if they stay away from predators. Hedgehogs and other mammals could be in for a more difficult time, however, since they were thought to be having babies much later in 2015 and when the cold conditions do eventually come, they may not have enough body fat to survive the winter. You may contact the British Hedgehog Preservation Society here if you see a hedgehog in distress. Click here to visit Nature Station’s website.
Take part in the Big Garden Birdwatch 2016
This is just a reminder that the Big Garden Birdwatch is due to take place over the weekend of 30 – 31 of January. More than half a million people have already registered to take part. If you wish to find out more click here, or go ahead and register your details here. As well as birds, other wildlife sightings will be recorded throughout the year, providing valuable information on nature in the UK.

BTO Goldfinch Survey
With Goldfinches becoming more popular visitors to people’s gardens the BTO has launched a survey to try and find out why. It is attempting to find answers to questions by studying their feeding habits. If you would like to read more about this please click here. Detailed instructions on how to participate in the survey are available here.

Red Squirrel Appeal
The Wildlife Ark Trust have launched a fundraising appeal on the JustGiving platform for £189,000 to pay for the modification of the Squirrel Pox Vaccine candidate. They are optimistic that if enough people become aware of the appeal their target will be hit. The hope is that if the message about the Wildlife Ark Trust appeal on JustGiving can get enough publicity it will go viral; the only difference being that on this occasion a ‘virus’ will be saving the red squirrels not killing them.
If you would like to help the appeal please let all your friends know about it then tell their friends about it and so on. The link to the justgiving page is http://goo.gl//ttGuBj.

The Wharfedale Naturalists are pleased to be able to continue their support for the Yorkshire Dales Millenium Trust’s ‘Hay Time’ programme, by contributing towards equipment. This will help in assisting them with their vital work to save the remaining species-rich hay meadows in the Yorkshire Dales. Previously, funding was provided for two leaf vacuums which have been well used and are in need of a service. In addition to this, a further petrol blower and vacuum kit will be provided and several replacement parts for the existing equipment.
If you would like to find out more about this project please click here. The Yorkshire Dales Millenium Trust would like to thank all members for this kind contribution.
Gallows Hill Nature Area
For those that aren’t familiar with Gallows Hill, it is situated to the east of Otley, off Pool Road, on the south bank of the river Wharfe (See the site boundary above). The site’s name has rather grizzly origins since it was once used as a site of execution dating back to the Anglo-Saxon period. Today, however, it is a popular spot for the local community to connect with its wildlife.
The site has a variety of different habitats including two ponds which support good amphibian communities. Its keystone species is a healthy population of Common Toad and there has also been a record of a Smooth Newt in recent times. The surrounding trees, scrub and nettle beds also provide good habitat for birds, butterflies and dragonflies.
Currently the Friends of Gallows Hill and Otley Town Council are putting a plan together on how best to manage the site and, as part of this, the Wharfedale Naturalists would like to encourage members to visit so more information can be found out about the wildlife there. If this description is of interest to you and you haven’t already, please consider popping along.
Big Butterfly Count 2015
This year may not have been the best year for butterflies, but more people than ever participated in the ‘big butterfly count’, 2015. Over 52,000 people took part with over 50,000 counts, 5,300 on a single day in August. The average number of individual butterflies seen in each count had a 9% reduction on last years counts, which is thought to be a result of the weather, but the number of target species in this year’s count showed an overall increase. The largest declines in abundance were shown in Northern Ireland (-41%) and Scotland (-37%), who experienced worse conditions than other regions, particularly in July. Out of the species that showed an increase on 2014 numbers; the Holy Blue showed the largest (+151%), followed by the Silver Y moth (+92%) and the Ringlet (+75%). The results for all 20 of the target butterflies and moths are shown below:

Yorkshire Mammal Group January Newsletter
The Yorkshire Mammal Group’s January Newsletter is available here. It lists their upcoming talks and other events for the month. If you haven’t done already you can also visit their website which has a calendar of events for 2016 here.
Butterfly Conservation’s Autumn Newsletter from Dave Hatton
Dave Hatton has published the Autumn Newsletter for the Yorkshire branch of Butterfly Conservation. The first half of the year was a quite dismal, which he puts down three very dry springs and two consecutive damp autumn / winter periods. The second half of the year saw an improvement with an increase in Peacock, Comma and Red Admiral counts. Some of the browns like the Gatekeeper, Marbled White, Meadow Brown and Ringlet also appeared to fare quite well.
To view the full report click here. Remember to send your 2015 records into Diane Morris and she will make sure BC receives them, after adding them to the Society’s database.
There are approximately 7000 species of amphibian in the world. That’s a lot of species to remember! Luckily the British Isles is home only 7, which makes things a lot easier. So roll up your sleeves and let’s get frog hunting as David explores how to identify British Amphibians in this video:
Yorkshire Red Kite Newsletter – Issue 16
Please find the Yorkshire Red Kite Newsletter (Issue 16) here. Red Kites have continued to thrive in Yorkshire and breeding pairs have now reached treble figures for the first time since their reintroduction in 1999. They can be quite a distraction when travelling through some regions. One breeding pair have reportedly raised nine young, which has given numbers an extra boost.

Since David Howson’s retirement, Diane Morris and Paul Millard have kindly offered to take over as butterfly recorders. As part of their new recording system, they have a new form, which they would like to encourage Wharfedale Naturalist members to use. This can be downloaded here along with some useful notes here. If you wish to print out a form and fill it in by hand, a suitable template is available here.
Diane would like to add that the butterfly recording should be a pleasure, and not a chore, so if you’re in doubt about anything on the spreadsheet please let her know, using the contact form below, or leave the entry blank.
Clicking send will forward your message to Diane.
Big Garden Birdwatch 2015
The Big Garden Birdwatch 2015 had over half a million participants and 8.5 million birds counted. In addition, people were asked to record other garden visitors such as slow worms, grass snakes, squirrels, deer, badgers and hedgehogs. The top ten birds seen this year were:
- House sparrow
- Blue tit
- Wood pigeon
- Great tit
- Collared dove
Out of the birds on the increase, Blackbirds were the most widely spotted garden bird, visiting more than 90 percent of people’s gardens. Robins have increased in popularity, jumping from 10th most popular in 2014, to 7th in 2015. Twice as many people saw Wrens this year than last and were spotted by 35 percent of participants.
Birds on the decline include the Song thrush, Greenfinch and Starling. Song thrushes are at an all-time low and have dropped to 22nd in the rankings and continue to remain on the red list of species. Greenfinches have plummeted to 25th place, which is the result of Trichomonosis, a parasitic disease, that has spread throughout the bird population, since it was first recognised, in 2005. It is thought the parasite may have jumped from Wood pigeon’s, who are carriers, to finches, at shared feeding stations. To help reduce further spread of the disease, the RSPB recommends giving bird feeders and bird baths a regular clean.
The next Big Garden Birdwatch takes place over the weekend of 30 and 31 January 2016. More information can be found by visiting the RSPB website here.
