As we come to the end of the year, Caledonian Conservation would like to thank all our clients for their custom. A good year, and much improved on the previous Covid-strewn years for which we can all be thankful.
We’re also thankful for our office dogs, Rufus and Rocket, who have joined the team with their owner Claire (our new administrator as of June).
They’re great therapy and company for everyone, even if they do have a rather vaporous presence at times . . .🤨 But they take Health & Safety very seriously, as you can see!
Talking of H&S, the year has been rounded off with a very well-run and much-enjoyed Outdoor First Aid course with First Aid Cooperative, so you can rest assured that the CalCon team are clued up on emergencies of all kinds, from a splinter to mountain rescue.
Wishing all our clients and network a warm and relaxing Christmas season!

Stop the press! New paper by Director Chris Cathrine and Ecologist Tony Monir about turtles at Glasgow Botanic Gardens. It first came to Chris’s attention on 19th January 2022 that there were several terrapins (a polyphyletic group of freshwater turtles belonging to Order Testudines) present in a greenhouse to the north of The Main Range at GBG. These terrapins seem not to have been recorded previously, although this is likely to be due to the fact the greenhouse in which they are located is not accessible to the general public. It was evident that at least three types were present!
Of the three types found, there were two subspecies of Trachemys scripta and a new species for Scotland - Mauremys reevesii

Back in August we were lucky enough to be invited to assist with bryophyte (moss and liverwort) recording on the Woodland Trust Glen Finglas estate. The recording day was instigated and lead by Jane Jones (Botanical Society of Britain and Ireland) and Gwen Raes (Woodland Trust Estate Ranger). We were also joined by Jack Ravenscroft (Woodland Trust Ecological Research volunteer) and bryophyte expert Gordon Rothero (British Bryological Society).
Gwen skilfully drove us along the long, steep track north east of Glen Finglas reservoir to Creagan nan Sgiath and the lower slopes of Ben Vane, which would otherwise have been a 27km round trip on foot from the Glen Finglas car park! I have experienced this particular walk (otherwise known as the Mell circuit) on a previous jaunt and can vouch it is long and gruelling and would certainly leave limited opportunity to search the upper crags for bryological treasures….although I was treated to spectacular close views of a golden eagle on that occasion…swings and roundabouts!
Getting a lift to the site meant we could focus our efforts on recording our target location…the calcareous montane crags Creagan nan Sgiath, where we recorded 99 species of moss and liverwort at heights of 450m to 650m a.s.l. The most interest was present on the highest calcareous crags where nationally scarce Encalypta ciliata, Scapania cuspiduligera, Scapania degenii and Bryum dixonii were recorded. The bryophytes recorded overall are a distinctive and reasonably diverse group which are localised but fairly typical of this habitat type - upland calcareous crags. There are frequent cushions of Grimmia funalis and occasionally occurring Anoectangium aestivum, Molendoa warburgii, Ditrichum gracile, Orthothecium intricatum, Thuidium delicatulum, Mnium marginatum and Plagiobryum zieri. One species, Racomitrium elongatum, was recognised as being a first for the vice county in which the site occurs (West Perthshire). This was recorded on gravelly soil on the lower slopes.
With a little time to spare on the drive back round the Mell circuit we climbed up towards a small incised ravine on the lower slopes beneath Creag a Mhadaidh north west of Ben Vane. The greatest interest was recorded in flushes below the ravine, not least from a splendid display of dozens of peacock butterflies amongst rushes and devil’s bit scabious, but with the addition of an assemblage of base demanding species including Campylium stellatum, Scorpidium cossonii, Scorpidium revolvens, Sphagnum contortum and Sphagnum inundatum. Their presence which indicates some base rich flushing spurred us on with promise for potentially interesting species in the ravine, but alas it would only be the precipitous climb into the ravine that got my heart going!
A good day of recording thanks to the team. There is still more scope for further recording in the glen with more unexplored crags to conquer!

On 17th March 2018, Director Chris Cathrine presented the results of Site Condition Monitoring invertebrate surveys at Sites of Special Scientific Interest (SSSIs) in Tayside, at the Tayside Recorders’ Day, in Perth. Some of the results of these surveys, completed between 2011 and 2017 under contract to Scottish Natural Heritage (SNH), have not been made publicly available before, other than as records on NBN Atlas.
Caledonian Conservation Ltd has completed Site Condition Monitoring of invertebrate features for 56 SSSIs in Scotland between 2011 and 2017 under contract SNH. Of these SSSIs, five were located in Tayside: Barry Links (2011), Black Wood of Rannoch (2013), Den of Airlie (2015), Dollar Glen (2013), and Methven Woods (2015).
Among the stand out finds were the rediscover of the extinct flutter-wing fly Palloptera laetabilis and finding other rare invertebrate such as the lichen running-spider (Philodromus margaritatus).
The conference presentation and article in the Tayside Recorders’ Bulleting which includes the conference proceedings can be downloaded via the Caledonian Conservation Ltd publications page.

A new guidance document for reptile survey and mitigation in peatland habitats has been published by Amphibian & Reptile Groups of the UK (ARG UK), supported by Froglife, the Herpetological Society of Ireland (the HSI), and Amphibian & Reptile Conservation Trust (ARC Trust). The publication of this document is significant, as there has long been a guidance vacuum for reptiles – this goes a small way to filling that gap.
All native reptile species are legally protected in the UK and Ireland, and so consideration should be given to mitigation to avoid committing an offence under the relevant nation-specific legislation (note that wildlife protection law is devolved and varies between individual UK countries).
The document, authored by Caledonian Conservation Ltd Director Chris Cathrine, focuses on Scotland where peatland habitats are extensive. However, it could be applied to England, Wales, Northern Ireland, or Ireland where peatland habitats also occur. The guidance is intended to assist in designing mitigation for impacts on reptiles during peatland restoration works but the methods described may also be suitable for the construction phase of some developments on these habitats. Similarly, some of the approaches described could be adapted, with care, for reptiles occurring on other habitats.
The guidance provides information on peatland reptile ecology, potential impacts, survey methods, and approaches to mitigation to avoid harm to reptiles and construct hibernation features. A decision tree flow chart is also provided, to help site managers to consider reptiles while planning works.
The new Reptile Survey and Mitigation Guidance for Peatland Habitats document can be downloaded at: https://www.arguk.org/info-advice/advice-notes/414-10-advice-note-10-reptile-survey-and-mitigation-guidance-for-peatland-habitats

While surveying for flies and butterflies during Site Condition Monitoring at Morrich More Site of Special Scientific Interest (SSSI) in 2015, Director Chris Cathrine made a surprising discovery when a big female Northern bear sider (Arctosa cinerea) ran on to his sweep net!
This is not only the most northerly record for the Northern bear spider in the UK, but is also the first documented example of the species using sandy habitats – in this case on a stabilised dune system. Although it has been found to use this habitat for some parts of its life cycle in Europe, it is typically found under stones in shingle in the UK.
You can read more about this discovery in an article in the latest issue of the latest issue of the Newsletter of the British Arachnological Society. The article is also available to read here, via the Caledonian Conservation Ltd publications page.

Although Director Chris Cathrine published an article on the implications of Brexit for Devolved Environmental Law in Scotland just three months ago, a lot has moved on since (read the blog on the original article here). Using responses received from UK Government and Scottish Government officials, as well as newly published documents, Chris authored an update article which has been published in the latest issue of Chartered Institute of Ecology and Environmental Management (CIEEM) In Practice. This new article adds clarity to the future of environmental law in Scotland, however there remains much uncertainty, particularly as UK Government responses to queries relating specifically to devolved law made reference to policy which only applies to England. The new article can be downloaded from the Caledonian Conservation publications page.
The politics of Brexit continue at a rapid pace, and since this article was written the UK Parliament has voted on a number of amendments to the EU Withdrawal Bill (formerly known as ‘the Great Repeal Bill’) relating to both the future of environmental law and devolution. Of particular note are the votes which rejected New Clause 67 and the amendments to Clause 11, the implications of which are summarised below:
Unfortunately, these developments since writing the update article have failed to add further clarity to devolved environmental law after Brexit, and instead have increased uncertainty.

Caledonian Conservation has been working to satisfy ecology planning conditions for RES at Freasdail Wind Farm in Kintyre since 2014, involving developing and delivering mitigation for a range of birds, mammals, reptiles and habitats, as well as providing Ecological Clerk of Works (ECoW) services. The final step in this process was the deployment of nest rafts to encourage red-throated divers – rare birds protected under Schedule 1 of the Wildlife and Countryside Act 1981 (as amended in Scotland) – to breed.
Red-throated divers spend winter at sea, and return to breeding territories (usually small lochans in open moorland) in spring. The nest consists of a small scrape, normally located at the water’s edge, or on an island. As nests are often located within easy access of predators such as foxes, otters and gulls, disturbance and predation can cause breeding failure. Nests are also vulnerable to flooding during incubation – an increasingly common problem as summers become wetter as a result of climate change.
Artificial nest rafts have been found to greatly improve the success of breeding divers. These rafts are not susceptible to flooding, as they adjust automatically with the water level, and also limit access to land-based predators.
To avoid disturbance, nest rafts were installed after the major elements of construction were complete. Locations for rafts were carefully chosen to avoid risk of collision with wind turbines while red-throated divers commute between nesting lochans and feeding habitat (the sea and larger waterbodies), and to ensure there would be no human-caused disturbance during operational maintenance activities.
Working with Simon Lawrence (Lawrence Environmental Consultants), the nest rafts were successfully installed by Caledonian Conservation in April 2017, and will hopefully improve the breeding success of red-throated divers in the area in future years.

A rare flutter-wing fly, Palloptera laetabilis, not seen in the UK for over 100 years has been found at Den of Airlie Site of Special Scientific Interest (SSSI), a woodland in Angus. This is also the first time this fly has ever been found in Scotland.
The rare fly was presumed to be extinct, but was found during site condition monitoring surveys completed by Caledonian Conservation under contract to Scottish Natural Heritage (SNH) in 2015. The discovery has since been confirmed and published by Steven Falk (the fly expert on the project team) in the most recent issue of Dipterists Digest.
Den of Airlie SSSI is only the fifth site that this species has been recorded at in the UK, and the only one in Scotland. The other four sites are all located in England, with the last record being from Oxfordshire in 1907.
Chris Cathrine, Director of Caledonian Conservation and project leader for the 2015 invertebrate site condition monitoring project said: “Finding a species last recorded over a century ago is very exciting. That this is also the first record for the species in Scotland makes this all the more special. We found a great number of rare species during our surveys across Scotland. While Palloptera laetabilis is undoubtedly the most exciting, we hope to publish records from all 25 sites, including the Isle of Rum, in the future.”
The invertebrate records collected by Caledonian Conservation during these surveys (including Den of Airlie SSSI) are available on NBN Atlas at: https://registry.nbnatlas.org/public/show/dp4

The winners of the Amazing Animals, Brilliant Science competition have been presented with their awards at Edinburgh Zoo, including Caledonian Conservation beanie hats!
Young artists and writers from across Scotland attended the event on 21st October, organised by the Amphibian and Reptile Conservation (ARC) Trust and hosted by the Royal Zoological Society of Scotland (RZSS). Children aged 8-18 were asked to paint, draw or write about 15 iconic Scottish species, ranging from Scottish wildcats and red deer to great crested newts. According to ARC's patron and TV presenter Chris Packham: "There are some very striking, imaginative and colourful artworks... and some tremendous essays describing these wonderful animals."
Caledonian Conservation were proud to sponsor the event, with Director Chris Cathrine saying: “Young people are losing their connection to the natural world. If people don’t care about wildlife, they won’t want to protect it. It is therefore essential to ensure that the next generation have the opportunity to explore and share in the wonder of Scotland’s wildlife. It’s an honour and a privilege to help young people build their connection with nature. Who knows, maybe some of the winners will go on to become the ecologists of the future.”
The creative work done by the children will now be used to help illustrate a new book called "Amazing Animals, Brilliant Science: how DNA technology is being used to help save Scotland's wildlife". The book is being compiled by Dr Pete Minting of ARC.
The Amazing Animals, Brilliant Science competition is part of ARC's Great Crested Newt Detectives project in Scotland, which started in April 2016 and runs until March 2018, funded by the Heritage Lottery Fund (HLF), Scottish Natural Heritage (SNH), the Royal Zoological Society of Scotland (RZSS) and ARC.
