On a hot sunny day at the end of August, I visited two contrasting sites. One was in the middle of a bustling city, the other deep in the countryside. Both are Avon Wildlife Trust nature reserves, providing vital space for wildlife within a less hospitable landscape.
At Brandon Hill Nature Park, in Bristol, the Trust has transformed five acres of city park into a wildlife haven. It is a core part of the My Wild City scheme, which aims to link up green spaces and create wildlife corridors to enable wildlife to move easily around the city and connect to the wider countryside.
It was certainly working for pollinating insects, the edges of the recently mown wildflower meadow were buzzing with bees. Butterflies danced from flower to flower, always one step ahead of the camera.
We climbed to the top of the Cabot Tower to see the city laid out around us, the River Avon a silver ribbon through the landscape. It was easy to see why Brandon Hill is an important stopping off point for migrating birds following the river valley.
After exploring Brandon Hill, we made our way to Folly Farm, about 10 miles to the south. Surrounded by farmland, the traditionally managed wildflower meadows and ancient woodlands of Folly Farm nature reserve provide 250 acres of wildlife habitat. At its heart is the Folly Farm centre, an award winning education, conference and wedding venue. Preparations were underway for a weekend wedding, so we didn’t get to peek at the buildings, but we were more than happy to spend our time out in the sunshine, and set of on a walk around the reserve.
Although it was late August, there were still plenty of flowers around, and blue butterflies flitted across the meadow like living confetti. Skylarks were tiny dark flecks of song in the hot blue sky and at one point I looked up to see five buzzards circling on the thermals above the hill, each one spiralling higher than the last.
It has taken such a long time to finish this series of blog posts about my wildlife journey around Britain. Partly because, once I got back, there was so much to catch up on, at work and at home, the time for writing just dissappeared. But I think that perhaps a part of me didn’t want the adventure to finish.
I had such a lovely time, saw amazing places and wildlife, and met many interesting, knowledgeable and dedicated Wildlife Trust people. I’d like to thank them all for being so kind and generous with their time, as well as for the work they do to ensure that all that wildlife is out there, for everyone to enjoy.
It is often said that most children are interested in nature, given the chance, but this interest gets lost somewhere along the way to adulthood. My daughters certainly became less indulgent as time went on, of my tendency to stop and look at every unusual plant and bug on family walks; teenagers, quite rightly, have different priorities. I sometimes wonder, now that they are leading city-based, millennial lives, how much connection with nature they have retained. Our busy lives rarely lend themselves to the kind of shared outdoor activities we used to enjoy, so when M came to join us for a weekend during our wildlife tour, I jumped at the chance of subjecting her to a bit of old-fashioned, seaside, family fun – rock-pooling.
Devon Wildlife Trust was running an “extreme rock-pool safari” from Wembury Marine Centre, near Plymouth. Extreme in the sense that it was on a particularly low spring tide, so the rocks would be uncovered further down the beach than usual, exposing marine wildlife that usually remains beneath the waves. It was also raining and extremely slippery. Cat, our Devon Wildlife Trust guide, vetoed M’s shoes, so I lent her my new walking boots, after extracting a promise that she wouldn’t go in above her ankles.
Cat led a group of all ages down the beach, scrambling over rocks to the waters edge. She explained the importance of putting everything back exactly where we had found it, including turning back any stones that we decided to search beneath. Some species spend all their lives in one small area and might not survive if randomly re-located.
Seasoned explorers then grabbed a tub and spread out to investigate the nearby pools whilst those of us who were less experienced gathered around whilst Cat pointed out some of the rock pool wildlife and explained how to identify it. Soon, there were cries of discovery, and we peered into the tubs to see the amazing creatures that people were bringing to Cat for identification.
At first, we had trouble finding anything, half-glimpsed shadowy shapes darted under seaweed and into crevices in the rocks as soon as we leant over pools. But we soon got the hang of turning over boulders to find all sorts of creatures clinging to the underside, or amongst the rocks and pebbles below.
Some fish, like these Cornish suckerfish, are well adapted to intertidal life and can survive out of water between tides in the damp conditions under rocks.

Velvet swimming crab
The stars of the day were the velvet swimming crabs, so-called because their shells are covered with fine hairs. Cat explained why these two were locked together:
Many of the animals we found were tiny and marvellously delicate. One of my favourites is the blue-rayed limpet. You find this at very low tides, clinging to the thick brown leathery fronds of kelp, a little translucent jewel with neon-blue dashed lines running along the shell.
We could happily have spent hours on the rocks, but the tide turned and eventually we had to head back up the beach. It was a brilliant way to spend an afternoon, and I learned that poking about in rock-pools never loses its charm.
Devon Wildlife Trust runs rock-pooling events at Wembury Marine Centre throughout the summer, many other Wildlife Trusts will run similar events, check their websites for details. You don’t have to wait for next summer, though. At Kent Wildlife Trust, we also have a year-round programme of Shore-search events, where you can come and help us identify and record the marine wildlife around Kent’s coast.
“Where would you like to go?”, Matt Boydell, the Land Manager, had asked when we spoke to arrange a visit to one of Devon Wildlife Trust‘s 50 nature reserves. A difficult choice, but I decided it would be good to see some lowland heathland, a habitat I’d not visited yet on my travels, and one which is in very short supply in Kent and getting rarer everywhere else. So in mid-August this year Matt took us to visit two Devon Wildlife Trust nature reserves, Bystock and Venn Ottery, both of which are part of the East Devon Pebblebed Heaths Special Area of Conservation, an area of lowland heath (named after the rounded pebbles in the sandstone deposits that lie beneath the soil ).
Bystock is a beautiful reserve containing a mixture of habitats. We walked across a rabbit-grazed meadow and through shady green woodland to where the site opened out into a purple sea of heathland, in full bloom in August and alive with the buzzing of bees. Threaded through the grass and heather were yellow tormentil flowers and the occasional golden splash of gorse.
There is a spring line running through the heathland; as we walked down the hill we came across two long ponds. This mix of wet and dry heathland, ponds and woodland is what makes the reserve incredibly rich in wildlife. There are 19 species of dragonflies and damselflies on the reserve, I’m not sure how many different ones we saw as they didn’t sit around waiting to be identified, but we were accompanied by flashes of blue, red and green as they darted across our path.
The site is really important for birds, particularly rare ground-nesting birds such as nightjar and Dartford warbler. Because they nest on the ground they are easily disturbed; Devon Wildlife Trust works hard not only to manage the site but also to help ensure that everyone can enjoy the site without affecting the wildlife. One of the ways they do this is by promoting the Dorset Dogs initiative, which has a membership group and lots of information sharing to encourage responsible dog ownership, including a code for owners to sign up to.
Traditionally, heathlands were kept open by grazing animals, which like to eat young growth including tree seedlings, so the heath didn’t become overgrown with trees and shrubs. Devon Wildlife Trust now uses Exmoor ponies to graze the heathland at Bystock and at Venn Ottery.
The dry open habitat is perfect for lizards and adders to bask in the sun, we saw lots of lizards on our walk round.
These are some of the heathland plants we saw:
Not sure what this fern is, I thought maybe Buckler fern. Any ideas?
Below the heathland we climbed down some steps to the edge of a lily covered lake. This is actually an old reservoir, as the site used to belong South West Water. Devon Wildlife Trust have been managing it for them since the 1990s and now own the site.
Quite a few people asked Matt about terrapins as we walked round the reserve. Terrapins were popular pets in the early 90s, when, inspired by the TV series and film, Teenage Mutant Ninja Turtles, people bought baby terrapins, about the size of a 50p coin. Actual teenage terrapins though, are bigger and feistier, so when they grew to the size of a dinner plate, many people abandoned their pets in local ponds and lakes. Unfortunately for the wildlife that already lives there, terrapins are voracious predators, eating just about anything they can swallow, and here they have a big impact on dragonflies as they eat their aquatic larvae.
As we got to the reservoir we found Ed and Andrew, the reserve wardens, lowering a terrapin trap into the water. The idea is that the terrapins, which like to bask on logs, will climb out to bask on the wooden frame which is mounted on plastic piping to keep it buoyant, and then plop back into the water and find themselves in the cage inside the frame. Any that are caught will be re-homed by a local tortoise collector. The terrapins aren’t the only introduced species found in the lake, Ed said that there are also Koi carp, one of which is called Henry by his fans.
The wet heathlands of the Pebblebed Heaths are fantastic habitats for dragonflies and damselflies including the very rare southern damselfly. This is only found at a few sites, and is very poor at colonising new ones. We went to Venn Ottery to look at the work that had been done to restore habitat so that it would be suitable for reintroducing southern damselflies.
The name Venn Ottery comes from fen, and means a marsh near the River Otter. We scrambled over the tussocky heathland and through a few boggy puddles to the middle of the reserve, where small streams have been dammed with wooden boards. This is to slow the movement of water and create suitable habitats for the damselfly, which lives in runnels – tiny shallow streams – on the heath. We didn’t manage to spot any, but it might have been just a little late in the year for them.
I’m incredibly grateful to Matt, for taking the time to show us around the reserves and to Ed and Andy for sharing their knowledge of the site, even though Ed was standing in leaky waders and quite keen to get some dry socks on. We had such a great time we went back the next day to take some extra photos and admire the wildlife.
Our wildlife tour had taken us right up to page 107 of my Road Atlas of Britain, along the Kyle of Durness and into the awe-inspiring Smoo Cave on the north coast of Scotland. After slowly heading south over a few weeks, we suddenly jumped to page 2, the far south-west of Britain, exploring Cornwall. What better place to search for damsels and dragons?
In truth, spend any bright summer day near freshwater and you will soon be captivated by the jewel-bright flashes of damselflies and dragonflies as they dart across ponds and lakes, or skim along rivers and streams. You don’t even need to be near water to see some species, we often saw hawker dragonflies as we walked along woodland paths. But the days we saw whole rainbow selections of damsels and dragons were those we spent in the West Country and North Wales. I’d like to attribute this to some mythical link, but actually I suspect we were just lucky with the weather.
Making the most of the warm Cornish sunshine, and feeling optimistically energetic, we set out from Devoran on the coast to coast cycle trail. After just a couple of miles I was excited to come across a Cornwall Wildlife Trust reserve sign. Hastily abandoning my bike, I went to investigate Bissoe Valley nature reserve. Noticing my absence after a while (it’s not unusual for me to be lagging a bit behind, I stop to look at things and probably don’t make a very good cycling companion) Geoff cycled back to the reserve, picked up my bike and parked it properly, and came to see what the distraction was this time. Just as well he did, as he took some fantastic photographs. All the images in this post are his, please credit Geoff Woolley if you want to use any.
This common darter dragonfly was very obliging for the camera.

Metallic green emerald damselflies with sapphire eyes shimmered across the pools. It is easiest to photograph them when they are “in tandem”, the male clasping the female behind her head. This is part of the mating process, the female will curl her tail round (technically, her abdomen) to the male so that sperm can be transferred.
We saw several other species, but unless they stayed still for a few moments it was impossible to photograph them. You will just have to visit a reserve to see for yourself – it’s not too late, you should see them on any warm day over the next few weeks. Meanwhile, here are a few more from our travels.
Shropshire Wildlife Trust has a fantastic HQ, beautiful old restored abbey buildings surrounded by gardens, that once housed the Cadfael Experience, celebrating the books and TV series about a medieval monk with detective leanings, set in Shrewsbury. The garden still has an old-world, kitchen garden feel, with herbs, vegetables and fruit trees promising an abundant harvest.
I was there to meet Jan Mckelvey, Conservation Manager at Shropshire Wildlife Trust, to find out more about the work of the Trust, especially how it runs behind the scenes. They have a lot of great projects running at the moment. I met the incredibly knowledgeable and enthusiastic team running an extensive landscape restoration scheme, The Meres and Mosses, and had a very interesting chat with Pete Lambert who manages the varied work that the Trust is doing to improve Shropshire’s rivers.
Of course I couldn’t visit Shropshire Wildlife Trust without seeing a nature reserve, so in the afternoon, clutching a map and set of directions, we braved the rain and set off to visit The Ercall, little sister to that more famous Shropshire landmark, the Wrekin.
The changeable weather enhanced our experience of the reserve. The Ercall is covered with ancient oak woodland, with moss covered trees, lush green ferny undergrowth, open grassy glades and small ponds. As we walked through the trees, the rain pattered softly through the leaves and gave everything an emerald glow.

Just as we reached the top of The Ercall, the clouds parted and the sun shone through, lighting up the woods and wet landscape in glorious technicolour.
The Ercall is hugely important geologically, the scars left by quarrying reveal that the area was once under a shallow tropical sea just south of the equator.

I loved this poem carved into stone, reflecting the site’s geological history.
Upon my shore you stand
A mark in time I am
And older yet than that
And under the sea I’ve seen
The birthing of this land
By pick and blast made now
It ripples on through me
A scar reclaimed by green
My secrets held in folds
Of quiet eternity
On that reflective note, I have to leave you with a gorgeous Shrewsbury sunset, one of the most fiery skies I saw on the whole trip.
Keen to try out another top UK wildlife experience, we headed to Cemlyn Bay, a North Wales Wildlife Trust reserve, seeking out one of the UK’s largest nesting tern colonies. Wear a hat for terns, the Wildlife Trusts’ website suggests, as terns are very protective of their nests and will dive bomb suspected intruders. No hats were needed, however, as the terns had just finished a busy summer of raising chicks, and most of the birds had dispersed.
Even one tern is worth watching though, and we stood spellbound on the beach as the few terns that were left wheeled and turned effortlessly, their finely pointed wings slicing through the air. Every now and then they paused to hover before folding back their wings and plunging into the water.
There were still plenty of birds to see on the islands in the lagoon that lies behind the long shingle spit, including a few more terns, oyster catchers and ringed plovers. A heron stood like a statue in the shallow water whilst a little egret stalked through the water. On the way round the circular walk that we explored, we saw a heron, possibly the same one, flying low over a field with long slow beats of its huge wings. The hedgerows were glowing with red campion, which seemed to grow more thickly along Anglesey lanes than anywhere else, intermingled with the softer purples of black knapweed and devilsbit scabious.

Another place to add to my list of reserves to revisit then, but next time I’ll come a little earlier in the summer.
I was struck by how many of the sites I’ve visited during this trip have been reclaimed from industry. Of course most Wildlife Trust nature reserves are habitats that have taken hundreds of years to establish and are now saved for the future, but something the Trusts are very good at is bringing wildlife back to areas that have been used for quite different purposes.
Gwaith Powdwr, at Penrhyndeudraeth, is one such site. In the 1970s it was the most sophisticated nitroglycerin manufacturing plant of its kind in the world. Production stopped in 1995, and it was decontaminated before being donated by ICI to North Wales Wildlife Trust, Ymddiriedolaeth Natur Gogledd Cymru, in 1998.
Due to the security requirements of the site, nature survived undisturbed in parts of the site, the heathland in particular has remained mostly ungrazed and is a haven for species such as adder and nightjar.
Wildlife started to reclaim the rest of the site once the factory was closed, bats moved into the buildings and structures and the site is now designated as a Site of Special Scientific Interest because of its importance for bats, especially the rare lesser horseshoe bat.
At the end of July, we joined Rob Booth, Living Landscapes Officer at NWWT, and his volunteers for their lunch break. They were busy getting ready for Party Penrhyn, an annual event at the site. Rob told us about the wildlife on the reserve and the work that is being done to encourage more wildlife.
The reserve provides ideal conditions for four kinds of reptiles. We saw lizards basking on old wood and bare patches of ground amongst the heather, and were given permission to peak under some reptile monitoring sheets, where bronze-sheened slow worms glinted in the sun before slipping further into the thatch of grass and old bracken. Adders are also to be found in the heathy parts of the site, but sadly not by us, although we searched carefully. In the midday heat they are far too quick for mere humans and would have been off as soon as they heard us coming. (Although snakes don’t appear to have ears, they can in fact hear, by sensing vibrations, including sound waves, which are passed through their jaw to an inner ear.)
As the reserve is so important for bats, much of the management is aimed at improving conditions for them. Lesser horseshoe bats use the tunnels and there are up to 30 hibernating on site but they don’t seem to breed there. The Trust managed to get a grant to re-roof one of the explosive storage sheds, and are hoping it will become a maternity roost. Since the work was done, brown long-eared bats have bred in there and Rob said that lesser horseshoe bats are already checking it out. The Trust is also working to make the bunkers more homely for bats, putting new doors on to prevent disturbance, reduce light levels and draughts and make them safer from predators.
The woodland on the reserve is particularly good for moths, the Trust found 130 species in just one night. Where a stream runs through the woodland, the damp, shady conditions are ideal for ferns and mosses.

Ponds were part of the industrial legacy, providing water to help keep the explosives cool (and therefore stable) and also allowing contaminants to settle out of the water. These settling ponds are now a wildlife haven, we saw lots of tiny toadlets setting off on their journey into the big world of dry land, stragglers from the great toadlet exodus that happens during July. The grass snakes that have been seen around the ponds proved elusive, which is probably fortunate for the toadlets. Dragonflies and damselflies darted across the water, rarely settling long enough to have their photographs taken, except by the most patient of photographers. Fortunately I had one with me.

We had such a brilliant time exploring Gwaith Powdwr, everywhere we looked there was interesting wildlife. It is a fantastic example of how a site can be restored after such intense industrial use.
