Newt survey log #1

Common or Smooth newt (Triturus vulgaris) – pic taken from Froglife

Last night Alex and I braved the darkness to peer into the depths of the various pools and ponds around Sutton Ecology Center. Armed with some huge, ominous looking survey flashlights we strode into the mild evening,  hoping to find and blind (joking!) as many newts as possible. Any toads, frogs and other beasties would be a nice bonus.
After a larva was found last year, we were really looking to find Great Crested Newt (Triturus cristatus) – arguably the ‘point’ of undertaking these surveys.
The Great Crested Newt (referred to by those in the know as GCN)  is protected by law as it is under threat by, and has greatly declined due to, habitat destruction

We started, lamps blazing, in the small pond to the east of the allotments. Despite only being a meter or so square, and not having much by way of subaquatic vegetation, we found 9 or 10 smooth or common newts (Triturus vulgaris), apparently quite happy floating about in the otherwise seemingly barren pool.

Next up were the two small raised ponds to the south of the main pond. Strangely, in the first we found no newts at all, despite what looked like perfect conditions. A pair of common toads (Bufo bufo) were something to look at, at least, although lack of spawn or tadpoles suggested that they weren’t a breeding pair.  Hopefully our by now slightly dimmer mood lighting will have done something to encourage a bit of Bufo rumpy-pumpy.

The second small pond held a bit more life, with another common toad and 5 or so more common newts hiding in the shadows of the foliage. A damselfly larva also made an appearance, thrashing wildly through the water towards the lamp light (probably not the best idea when you’re in a pond full of potential predators). We left our damsel in distress to whatever grisly end may have befallen it…

Onto the main act of the show and our lamps were unfortunately already beginning to cough and splutter a bit. We started with the small pool by the pond shed and counted a bumper 16 common newts, some flashing their vibrant orange bellies as we scanned through the depths, the males showing off their wavy crests that they grow during the breeding season. We also spotted a couple of large freshwater leeches stretching themselves out of the water onto dry land – behaviour I was previously unaware of!

Unfortunately, by the time we got to the main pond, the torches were really suffering. We managed to spot another 10 or so smooth newts by the pond dipping platform before our lamps flickered and spluttered and died. Switching to a far less effective LED torch we managed to pick up a couple more ‘maybes’ on our way around the perimeter, but ultimately couldn’t properly survey the main pond.

Despite that disappointment, it was an interesting way to spend an evening, and something I can’t wait to repeat.  Assuming we can source some more reliable torches, stay tuned for a (hopefully more successful!) Newt Survey log #2 in the near future!

Marvel at Mosses – a learning opportunity!

Marvel_mosses

Have you ever wondered about the carpet of spongy, wet greenery on the woodland floor, or strange, small cushions poking out of cracks in walls and pavements?

Called Bryophytes (incorporating Mosses, Liverworts and Hornworts), these tiny, insignificant looking plants can be easy to overlook and hard to identify, but their importance cannot be overstated – Bryophytes are the closest modern relatives of the pioneering ancestral plants that first escaped the sea and colonised land.

Their role in the environment remains highly important. Bryophytes are often the first plants to colonise recently disturbed land, allowing other plants to follow, and retain water, acting as mini-flood defences and also affording a supply of water to other organisms during dry spells.

If these wonderful plants sound interesting to you,  why not come along to a free beginner’s session perfect for budding bryophiles? 29th April, 10am-4pm at Stonecourt classroom in Carshalton.

An introduction to the marvellous world of mosses and liverworts.
The day will involve an indoor study session looking at the field characters and life cycles of these fascinating plants, followed by an outdoor session looking at the common species found in the local area. The tutor for the day will be bryologist, Peter Howarth.

Latest Task Programme – Now Out !

The new task programme is now out

March – June 2017

As the weather starts to show signs of improving, so habitat improvement activities are set to exploit the warmer temperatures and increasing day light hours.

With hundreds of plants, seeds and trees set to grace the lighter conditions at Queen Mary’s Woodland, created over the last twelve months or so, now is a great time to help improve this local nature site.

With a number of  mid week and weekend Task Days planned for the next couple of months come and join fellow SNCV volunteers as they continue to celebrate 30 years of ‘Helping Wildlife on Sutton’s Doorstep’.

Risk Assessments: Keeping Volunteers Safe

bopnoglogIn every task the Sutton Nature Conservation Volunteers undertake, there are varying elements of risk.
From the moment we start loading the van to when we leave a site at the end of the day (even when having a cup of tea!) there’s a chance that someone may get hurt. Fortunately, the only injuries sustained on task days have thus far been minor, and long may that situation remain the same.

It is due to these risks that the Biodiversity team have decided to reevaluate and expand on their risk assessments for each nature site, ensuring that volunteers are aware of any changes or tweaks in the assessment.
Previously, risk assessments have been conveyed through short, casual talks throughout the day depending on the task at hand and the tools being used. This technique has served us well over the years, shown by the very low accident and injury rate. While the volunteers are aware of the risks inherent in various jobs and have been briefed on how to minimise the dangers encountered in the field, as all of the assessments have been delivered orally, there is no written record of it and therefore a liability on the Biodiversity team’s part if someone was to get hurt.

In order to remedy this in future, detailed risk assessments will be available for each site and will be signed by each volunteer before heading out on a task day. Initially at least, the task leader will go through the risk assessment thoroughly with the volunteers to ensure everyone fully appreciates what the day will entail before signing it. This can cost us some time on task days but will be worth it to keep everyone safe. Once the risk assessments become more familiar it may be appropriate to change to a less in depth ‘skim’ of the assessment, with a more conversational aspect. We won’t have to sit through a lecture each morning forever!

Through these talks, everyone involved in task day activities should become more aware of the specific risks involved in different tasks and sites.
A greater understanding of the risks and risk mitigation involved in planning a task day will be another step towards empowering the Sutton Nature Conservation Volunteers, allowing further autonomy and independence.
With the recent(ish) First Aid, Manual Handling and Risk Assessment training for volunteers a large body of communal knowledge is being built.
Knowledge is power, so soon enough we’ll be taking over the world and filling it with wild flowers!

Why did the mushroom go to the party?

Because he was a fungi!

Sorry, I had to get the groaner out of the way, as the temptation would probably be too much to bear later on.

Over the last few months I have been conducting mini fungi surveys, jotting down whatever fungal growth I’ve seen and can identify at our sites on SNCV task days. I’ve been mushroom hunting for years, but I’m certainly no expert – I used to only be interested in those I could eat!

The idea is to build up a bank of information on the species present on our sites to keep a track of our fungal diversity, as we have done with flora and fauna for many years. Hopefully, over time we will see the work of the SNCV and Biodiversity team positively affecting the diversity of fungi in the borough.

Fly Agaric (Amanita muscaria)

So, what constitutes a fungus? Some people reading this may be thinking of a mushroom, perhaps with a large red cap and white spots, much beloved by Mario. Chances are you’re thinking of something very much like the common woodland mushroom Fly Agaric (Amanita muscaria – above).

Alas, it isn’t that simple, fungi come in all shapes, sizes and colours. From classic ‘cap and stem’ mushrooms, to hard woody brackets, to jelly like blobs, to almost invisible wood rotting fungi, to tiny microbial fungi only visible through a microscope, there is an awful lot of variation in form. To make things even more confusing the lines are blurred between fungi, lichens (a symbiotic ‘multiple organism’ made up of fungus and algae) and slime moulds (which are often studied alongside fungi, despite actually being in a different taxonomic kingdom all together – they are Protists).

slime_2

Not a fungus, a slime mold!  Found at Roundshaw woods (Looks like Trichia decipiens – but not sure.)

However, even ignoring these confusions, a fungus is more than meets the eye. What we see as a mushroom, or a bracket on the side of a tree is merely the ‘fruit’ of the organism, basically a reproductive organ that allows spores to mature, be released and germinate elsewhere. These fruiting bodies are mostly quite short lived, and can appear at different times of year – or not appear at all depending on heat, rainfall and other environmental conditions. In order to accurately log species present on a site, year round surveillance is needed, so I’ve got my work cut out!

To use a slightly cheesy cliché, the fruiting body is just the tip of the iceberg. The main bulk of the fungus lives in the soil or wood substrate as a complex network of fibres called hyphae, known collectively as a mycelium. This is where some of the most important roles of fungi take place, as it is where nutrients are transferred.

Through the mycelium, fungi can break down matter and intake and excrete nutrients. For  decaying or ‘saprotrophic’ fungi, this enables rotting and decomposition in organic matter such as wood, dead leaves and dung, making these fungi incredibly important for any healthy ecosystem.
While there are bacteria that can also decay organic material, fungi are known as ‘the great recyclers’. An absence of fungus would cause the world to quickly fill up with dead plant and animal matter. Being buried under trees and dead bodies isn’t a particularly pleasant thought, so hooray for the mushies breaking it all down!

It isn’t all destruction though. The fungi break down and transport materials that would otherwise be unavailable to other organisms, increasing soil fertility and balancing nutrient deposits in soil.

Many fungi, particularly cap and stem mushrooms, form symbiotic relationships with plants and animals. In plants, the fungus will absorb nutrients such as sugars from the plant’s roots and in turn release nutrients like phosphorus and water, that the plant needs to survive.

Almost all terrestrial plants have been known to build these relationships with fungi, intertwining roots and mycelium. These mutually beneficial relationships are known as mycorrhizae, and are vitally important to the survival of many plants. Many orchids, for instance, cannot germinate at all without receiving nutrients from a fungal partner, and all orchids form mycorrhizal relationships at some point in their life cycle.

So fungi is both responsible for promoting plant growth, and plant decomposition – like a bizarre doting yet cannibalistic mother.

Of course, the mushrooms, toadstools and bracket-like fruiting bodies of fungi are an invaluable food source not only for us humans, but for a whole host of fungivore animals including mammals, molluscs and insects. Some insects such as fungal gnats (Mycetophilidae) use certain types of fungus as their larval host and main food source.

Unfortunately, despite their many beautiful forms and myriad ecological uses, the kingdom fungi is still not regarded with the same gravitas as animals and plants. In fact, it’s only relatively recently that fungi was formally recognised as it’s own taxonomic kingdom, finally being split from plants in 1969.

Fungi have had a bad press in general, too. With people assuming all toadstools are poisonous, or eradicating fungi from their gardens for ruining their lawns (to be fair, some fungi is incredibly poisonous, and some can cause widespread problems like food shortages by infecting crops – but I’m hardly going to mention that in a pro-fungi post, am I?). And the number of times my mere mention of fungi has caused people to collapse into a fervour of nudging, winking and cracking jokes about hippies is ridiculous.

Attitudes are changing, though. Over the past few decades, as ecology and biodiversity have by necessity become more widely discussed, so too has interest in fungal diversity increased.

Organisations such as the British Mycological Society and Plantlife along with local fungi groups and larger groups worldwide have long been encouraging awareness of fungi and educating people about their vital roles in our ecosystems. Due to these efforts people are starting to appreciate the beauty and importance of these organisms, with various species being identified as priority at risk species by the UK Biodiversity Action Plan and via the IUCN’s RED list. There are even protected species of fungi and lichen covered by law in the UK’s Wildlife and Countryside Act (even though they’re still bunged in with the plants – but you can’t have everything).

So far I have found many very common, almost ubiquitous species on all the sites that I have checked, plus a handful of unusual types that were new to me. One of the joys of these searches is finding something bizarre or beautiful but very common, like Jelly Ear (Auricularia auricula-judae, above) or Dead Man’s Fingers (Xylaria polymorpha) and seeing other volunteers regard them with wonder as I did when I first found them.

A sentiment that I found true when I first became interested in fungi and one that I hear echoed every time I show someone something new is that once you open your eyes to the world of fungi, there’s a heck of a lot to see.

I hope this little introduction has done something to get people interested in fungi in the London Borough of Sutton – I’ll be sure to update you all on what I find in the coming months.

Thanks for reading, now go and find some fungi!

Job Advert for Biodiversity Assistant. Why you should apply – a Biodiversity Assistant’s perspective!

Sutton Nature Conservation Volunteers and London Borough of Sutton’s Biodiversity team are looking for a second Biodiversity Assistant.

I have been in the role for a good few months now and am enjoying it immensely. Here’s why you should join me…

Since October I have been helping the Biodiversity team in their duties from leading volunteer task days to admin and paperwork in the office. The second part may sound a little boring but it has opened my eyes to the ‘behind the scenes’ work that accompanies the practical conservation that Sutton Nature Conservation Volunteers help to carry out.

Personally it has thus far been a valuable learning experience. I had a little insight of the work I would be undertaking from talking to the Biodiversity team and my previous volunteering with SNCV, but was not aware of the immensity of the work undertaken by them.

I came to be the Biodiversity Assistant after over a year of volunteering experience with SNCV, so I was already familiar with the types of practical work done throughout the year and it has been thoroughly rewarding to get more involved with the organisation and leading of task days with the volunteers, learning new skills along the way.

Our task days involve a variety of activities, changing with the seasons. Since October we have of course been doing more ‘wintery’ work (which you can mentally exchange with ‘hard’ work) such as reed pulling, coppicing and felling. These jobs may well be hard, but they are certainly satisfying. Looking back at a newly created laund reduced from thick foliage, or an icy pond once dense with reeds at the end of the day is a great feeling.

While I have enjoyed these jobs very much, there’s a part of me (my back, mainly) that is looking forward to the survey season of spring and early summer! Just don’t remind me about the heavy raking work when it’s time for the meadows to be cut.

Speaking of surveys, my first job in the office was to draw maps for the Phase 1 botanical surveys we had undertaken in the preceding year, or ‘a bit of colouring’ as Dave Warburton the Biodiversity Officer described it. I had assisted with the surveying in the past but was unaware of this extra step, creating an easily recognisable and standardised map to show an overview of a site’s habitat. Just one example of the ‘behind the scenes’ work I hadn’t foreseen, but a job which while being interesting is also quite relaxing – mindfulness drawing, eat your heart out!

My days in the office are often spent doing admin work, managing the website and emails,  data entry/analysis, or writing and researching blog posts. I really do enjoy all of it, particularly the latter. Could you tell from this rambling blog post?
The work I am undertaking here is paving the way towards a job in Ecology, picking up new skills all the time and being challenged in new ways.

Being a Biodiversity Assistant is a joy, I’d highly reccommend it.

If you’d like to be one too, click here to view the job specification, and apply as instructed.

Hope to see you soon!

Tough decisions : The cost of cuts

Some of you may have seen the post that we shared on Facebook earlier today regarding the funding arrangement between Surrey County Council and Surrey Wildlife Trust. Whilst we have removed the post, as we have been made aware that there were some inaccuracies in the information we shared, the case does raise cause for concern.

Surrey Wildlife Trust announced last week the restructuring of its countryside management team, following budget cuts by Surrey County Council. Government cuts mean the council can no longer afford to pay for its countryside estate and SCC wants it to become self-financing by 2021.

With many local authorities facing unprecedented budget cuts, local councillors are making difficult decisions about where money should be spent. As there are many services which councils have a statutory obligation to provide, cuts and reductions are invariably being felt in services which are not mandatory. Regrettably such cuts are most likely to be felt by silent services which may not have a large number of users but which we probably all enjoy and cherish, either directly or indirectly.

In the case that was highlighted it is clear that Surrey Wildlife Trust is having to take tough decisions about how it continues to manage the natural habitats it looks after, in face of the reduced budget it is receiving.

As wildlife doesn’t respect administrative boundaries what happens in Surrey could have an impact in Sutton or other neighbouring areas. Where Sutton’s nature sites enjoy the benefit of proximity to populations of species in Surrey’s habitat, any changes over the border could have an impact on Sutton’s sites.

As budget cuts have the potential to impact upon areas of everyday life far beyond the frequency of bin collections, the need to know what decisions are being taken is vital. Petitions are one way of being made aware and recording your opinion, but it is important that all the information is considered. There are other ways of finding out about local issues and changes that may be planned. Charities and other interest groups will often highlight things that are expected to impact their area of activity, but councils and other authorities will also have a way of briefing local people as well as enabling them to share views and opinions.

Whilst there may be no way of avoiding the need for cuts to services, engaging with decision makers at an early stage of the process will provide the best chance for the public’s views and opinions to influence the final decisions.

Sutton has not been immune from it’s own budget cuts and for the last few years Sutton Council has been embarking on changes which will shape Sutton’s Future. You may not have given much thought to the services that the Council provides, and the impact of changes to the way they are funded or how the Local Plan may affect the green spaces and places we enjoy.

In order to ensure that the things we cherish and value are given the utmost consideration by those who influence their future we urge you to investigate how to get your opinions known.
