An Alternative Natural History of Sussex.
This blog shows the highlights of my day to day findings as a naturalist and ecologist living and working in Sussex. Delivered with a pinch of nihilism, a dash of sarcasm and absolutely no tweeness, here is my attempt to show natural history as it really is: Brutal, beautiful, uncompromising and fascinating...and occasionally ridiculous.
I have been studying natural history for some thirty years, nineteen in a professional capacity. I currently work in Sussex as a freelance entomologist, ecologist and botanist and specialise in nature reserve and rewilding management advice based on the interpretation of the surveys I carry out. I also run a number of identification courses. An advocate of the pan-species listing approach. My main areas of interest are birds, plants and invertebrates and a lot of my spare time is spent in the field. I am the county recorder for spiders and bugs.
On Sunday, I breached the 1,000 species mark on a fantastic and rather unplanned trip out with the local British Bryological Society to Sullington Manor Farm, all down to bumping into Ben Benatt at Pulborough Brooks RSPB Reserve the day before. So let's call the 1,000th species I have seen this year Golden-eye Lichen Teloschistes chrysophthalmus. I am actually on 1,025 species as of Sunday, that's 17.1% of the challenge completed.
Saturday saw my attempt to go bird watching on a bird reserve with a telescope for like, the first time in about 15 years. So, Pulborough is a huge lake at the moment but boy did I find it hard work. The restrictive nature of being in a hide, scanning back and forth along a single plain used to be something I loved 20 to 30 years ago. Now, I just couldn't concentrate! I really think its PSL that's changed this for me, the chances of me finding something new or rare here were really low, while out on the heath sieving moss or vaccuming heather would have the potential to generate something really exciting. I did tick off most of the common wintering ducks, as well as finally seeing a Greenfinch (I saw a fifth of the UK's spiders before I saw one this year - bonkers). A distant Marsh Harrier was welcome. I still haven't seen Greylag though, and I proper dipped on the White-fronted Goose and Little Gull by not being able to figure out what end of my 'scope to look down, whilst day dreaming about sieving moss for tiny rare money spiders.
The RSPB staff were really really helpful, and let me do a bit of pond dipping at the centre. This got me a few nice species in return for the records. The Nationally Scarce Peltodytes caesus was a nice water beetle record, and it was good to tick off some common aquatic snails like this Giant Ramshorn. Why do I look so sinister here? I was actually trying to smile (that's a Giant Ramshorn and not an Oreo by the way). Also, that's the same telescope I have had since I was 11. And there were two Great White Egrets about 1.5 mile behind me that I ticked, thanks to the RSPB!
I then spent a few hours on Wiggonholt Common with Karen looking for spiders and other inverts. Seeing three Jack Snipe, five Snipe and two Woodock was much more like my kind of birding. I beat this Rhopalus rufus off some Gorse, this is a Nationally Rare bug that seems to be doing well on the West Sussex heaths but I don't think I have had it this far east yet.
And I sieved this Heather Shieldbug from some moss.
We headed to some very old pine stumps and Karen spotted this odd resupinate fungi under a few logs. I am pretty sure this is quite a rare fungus - Orange Netcrust Pseudomerulius aureus. The literature states it is rarely recorded on very old pine timber in the south east, almost always on heaths. Might it be a county first? There are no records on the NBN, or in the SxBRC. I am waiting for confirmation from the county recorder. Exciting!
EDIT: Not that exciting, it's not that species. Thanks to Stewart Wright, I believe this is likely to be Serpula himantioides. Still a lifer though.
Well done to Karen for finding this and thanks for remembering to take some action shots! And thanks to the RSPB for allowing access in exchange for the records, as this is not a publicly accessible heathland.
Then, I took a gamble on Sunday and it payed off. The forecast was no way near as bad as predicted and I ended up with some lifers! Three lichens and three mosses, thanks to Ben Benatt, Sue Rubenstein, Brad Scott and Sim Elliot. Yet the rarest thing I found was a spider. When we got to the chalk, I spotted a sub adult male Eratigena picta. An entirely new site for this Nationally Rare and Vulnerable spider (but also it would seem, very close to where I have found them on the Norfolk Estate in the last two years). Here's my map with the new record being the most north easterly one, still in TQ01 but very close to TQ11 now. I bet it's already there. Here are my records for the species now, with the western-most record the known site of Amberley Chalk Pit. I reckon I might have doubled the number of people who have seen this spider on Sunday!
The team found some Neckera smithii (was Leptodon) in Sullington Church Yard. I am on 85 species of bryophyte for the year now, that's 85% of my bryophyte target reached - I don't think I will fail to achieve this one now. Good to see, as it appears to have gone from Woods Mill now.
And this Nationally Scarce pink dust (now called Ingaderia vandenboomii because, why not?! - Llimonaea sorediata just wasn't exotic enough sounding for it), that grows on the north faces of old churches was one I have wanted to see for some time, as the late Simon Davey used to often talk about this species. If you imagine you had some pink wafers in a biscuit tin, but when you went to eat one, they'd all been snaffled by your greedy relatives, bar some crumbs in the bottom of the barrel - this is what this lichen looks like. Here it is responding strongly and rapidly to C+. Thanks to Ben and Sim for this one.
A lovely old track with old Ash and Field Maple was a real treat, I added Yellowhammer on call finally. I finally caught up with Ocypus olens under a stone and Nanogona polydesmoides under a log. The ludicrously small moss Seligeria calycina is always nice to 'see'. Here it is fruiting well on a lump of chalk.
Once we got to the chalk grassland, I had a fly over Corn Bunting new for the year. It was here I found the Eratigena picta.
There's plenty of Juniper here, this produced the Juniper Shiedlbug on demand for those that had never seen one. The diminutive Microbryum rectum made one very immature member of the group make some childish jokes, something I would never do. Anyways, after Brad bent down to show me his diminutive rectum, we headed on up the hill just as the rain started.
Ben found a significant patch of the Nationally Scarce Tortella squarrosa, a nice plant! Time to head back before we got proper soaked. I absolutely loved this day, lots of different complementary skill sets, with all of us learning from, and teaching, each other. A perfect day of natural history.
So, I ended the weekend on 1,025 species. Here's the exciting thing, of these 1,025 species, 519 (more than half) are invertebrates. I am very keen to use this challenge to show people that invertebrates do not disappear over the winter, there is lots to be found (and not just spiders). But also, this is a reminder that cutting everything all at once, or grazing really hard everywhere over the winter is bad for invertebrates, you need to leave some overwintering habitat. Otherwise, where are they going to go? Invertebrates don't just disappear in the winter, many overwinter as adults too.
Many thank to everyone who has sponsored me so far, please do consider sponsoring me if you can, I am fund raising for Sussex Wildlife Trust's reserves here.
You can sign up to the pan-species listing website here, it's totally free (although donations to the team are welcome).
And finally, my book is due to be released on the 26th Feb, less than a month to go!!! You can pre-order it here, directly from Pelagic.
Next up, I will be heading to East Sussex for some vegetated shingle...
I had a great (although very hot) week at Amberley last week with Mark Gurney and Sarah Fisk from the RSPB. We were finishing off an aquatic plant survey of the ditches that we started this time last year. I had a few new species including Whorl-grass but the real excitement came in the form of this sedge. True Fox Sedge Carex vulpina is much, much rarer than False Fox Sedge Carex otrubae. We left the ditches that True Fox Sedge was last recorded in, by James Cadbury, until the last day. Sarah spotted this sedge and I thought it looked quite different with a darker and broader inflorescence, shorter bract and more winged stem. We called Mark over and he began to get quite animated. Well, for Mark! He was keen to take some specimens to clinch the ID and it's the epidermis of the utricles at magnification which confirmed it. Here is True Fox Sedge with roughly square cells:
And False Fox Sedge with its elongated cells. A big thank you to Mark for sending the photos over.
So it's simple. We had True Fox Sedge. But how can we be sure that it wasn't just False Fox Sedge lying? You could just watch this and make your own mind up...
Sea kayaking at Coral Bay in Connemara was awesome. Arctic Terns were flying overhead and we even had a go at a bit of snorkeling. I am thinking I might have to get into diving. On the way back from Connemara to Castlebar, we stopped by some rather impressive bogs and found these amazing Water Lobelias which were a new one for me. We did get seriously attacked by midges and ticks though which wasn't much fun. Even the plants in Ireland are carnivorous but fortunately they eat the midges and not tourists. In the week we recordered all three sundews, all three butterworts and Lesser Bladderwort too.
Earlier that day we had a look around Connemra National Park, where the showy St Dabeoc's Heath could be found.
This little hoverfly was a new one for me, being the north-western species of Chrysotoxum, Chrysotoxum arcuatum.
I got my eye in too for these really cool black and green cushion-forming acrocarps that I was seeing in the bogs, it's Campylopus atrovirens.
Connemara really is a beautiful place (despite the midges). Next up, I go further west than I have ever been before...
