Writtle Wildlife Watch, June 2015

One of the joys of being a lecturer on the Conservation scheme here at Writtle is that you get to visit some wonderful places. And this year we took our first and second year students away for a week to the glorious area of the south coast, the New Forest. 

 

Maiden Castle, Dorchester

During what the Two Ronnies might have called ‘a packed programme’, (goodness, that makes me feel positively antediluvian!) we went all over Hampshire, Dorset and Wiltshire, visiting some great sites and talking to people working in a huge variety of Conservation jobs. 

 

For me though, the mini-highlight was on the Thursday when we stopped off to have a look at Maiden Castle, a magnificent Iron Age hillfort just south of Dorchester. Always impressive and giving beautiful views over the surrounding countryside, it is a particularly good spot for finding various birds such as Linnet, Skylark and Corn Bunting. And I thought that was all we were going to find but on the way down, student Jimmy suddenly stopped and said ‘Alan, what’s this funny beetle?’. 

 

Oil Beetle at Maiden Castle

Now, many species of insect are special but then there are others which really have the ‘wow’ factor. And Jimmy had found one of the latter – an Oil Beetle. 

 

Oil Beetles are peculiar and charming in equal measure. They are rather odd to look at, with an elongated body and narrow head, but have an exquisitely glossy sheen of black, violet and blue. They are totally reliant on solitary bees for the completion of their lifecycle, with the beetle larvae climbing flower-stems and waiting in flowers in order to hitch a ride on a passing bee. Back in the bee’s nest the larvae of the beetle feeds on its eggs, as well as the stores of nectar and pollen before emerging as an adult. 

 

We have lost three of our species in recent years and now only five are left. They favour flower-rich grasslands of the type found at Maiden Castle but sadly, we have lost many of these sites in recent decades, making an encounter with an Oil Beetle even more special.

 

Yes, we did see a Corn Bunting as we left but somehow it wasn’t the best wildlife sighting that day.

Writtle Wildlife Watch (June 2014)

Writtle Wildlife Watch returns for June! Alan Roscoe is at it again and once more keeps track of the fascinating wildlife on campus! 

--------------------------------------------------------------------------------------------------------------

I hope most of you caught up with the recent Springwatch programmes from Minsmere. Apparently the visitor numbers were up a staggering 50% as a result of the TV coverage although you do have to wonder whether the additional visitors were more excited about seeing Chris Packham than the wildlife!

It is good to see the BBC committing so much resource to programmes like this although (curmudgeonly grouch face on) just occasionally I wonder whether there is an overemphasis on the birds and the mammals – which, of course, the public enjoy – at the expense of the plants and other groups such as lichens and mosses. These are just as fascinating as the popular animal groups but, perhaps because they do not move, they are less appealing to the general public.

We monitor a range of animal species on our own College estate but we also keep an eye open for unusual plants and now is the best time of year for many orchid species. We are lucky enough to have both Bee Orchid and Pyramidal Orchid on our estate and, due to the sharp eyes of a colleague (well spotted Roy), we have found a new site for them this year. Pyramidal is pollinated by moths and butterflies which visit the plant not for nectar, but for a watery liquid which is found inside the ‘spur’ part of the flower. Grains of pollen are then picked up on the insect’s tongue and the perfect symbiosis of this particular species and its pollinating insects was even remarked upon by Charles Darwin himself.

Writtle Wildlife Watch (February 2014)

Writtle Conservation lecturer, Alan Roscoe, updates us on his latest 'Writtle Wildlife Watch'.

"A couple of months back I mentioned the recent storms and flooding but such has been their impact I feel I have to mention them again before Spring arrives.

Clearly you don’t have to live on the Somerset Levels to be aware of the potential for damage and even here, in warm and sheltered Essex (where the sun shines every day!) we have had some clearing up to do. This week we were out with our first years clearing away some trees which had come down across the green lane which crosses our estate just to let local residents and horses through.

UK floods in 2014

There has been much debate on comments pages attached to BBC website news stories with many contributors. And, yes, I am among them – see if you can spot my comments! Unfortunately, to paraphrase Mrs Merton (c.1997), many people seem to have taken the story as an excuse for a ‘heated debate’. But apart from the rather predictable ‘I blame the farmers / RSPB / Environment Agency / insert name of enemy here’ comments, there have also been some really interesting observations about the root causes of flooding, the nature of our countryside, what we expect from it and how to mitigate – and I cannot, hand on heart, say ‘avoid’ – such significant floods in the future. The most recent piece on the subject is at:

http://www.bbc.co.uk/news/science-environment-26466653

Perhaps now is the moment when we have that national (unheated) debate about our competing demands on our countryside, its aesthetics, its purpose and its future."

Writtle Wildlife Watch (January 2014)

Conservation Lecturer, Alan Roscoe, is back to provide us with a captivating update about wildlife around the Writtle College campus. Read Alan's discoveries for the start of 2014!

--------------------------------------------------------------------------------------------------------------

"When I was a lad (as they say) nothing was quite as thrilling as seeing a Kestrel hovering by the side of a motorway, its elegant wings braced against the wind as its finely-tuned eyes scanned for prey below, and its tail working furiously to keep its head stock-still in the breeze. The species was all the more meaningful to this young birder as it was also the emblem of the Young Ornithologists’ Club, the junior section of the RSPB at that time. (Goodness, who uses the word ‘ornithologist’ nowadays?)

Whilst many birds of prey have prospered in recent years though, the Kestrel has, for reasons which are not quite clear, declined at a rather unpleasant rate. Help is at hand however, as its plight has already been recognised and conservation groups are taking action.

Working with Essex Birdwatching Society and our colleagues on the College farm, we are now installing Kestrel boxes on our estate to help encourage the local population. 

This will supplement the Barn Owl boxes we put up a couple of years ago (see below).

With any luck, we shall have some student volunteers this year to help monitor the nests. Which means that at least I will be spared climbing up those high ladders…."

Writtle Wildlife Watch (December 2013)

Writtle conservation expert, Alan Roscoe, has once again been observing the wildlife on campus at Writtle. Here, Alan reviews his December findings.

--------------------------------------------------------------------------------------------------------------

"I am sure you have seen the recent pictures from around the country of the devastation caused by high winds, surge tides and heavy rain. Our human infrastructure can seem very frail when confronted with these challenges.

But have you ever thought about the impact on wildlife – and do you always assume it will be bad…?

One of the things which has been lacking in the British countryside in recent decades is dead wood – a great habitat for numerous species, especially beetles. But because we are such a tidy nation, we have been obsessed with clearing up any tree which falls over in high wind. Consequently there has not been much dead wood around, until recently, that is. But now we have plenty of it!

One of the insects which needs dead wood is the Stag Beetle. This wonderful creature is found in parts of Essex and to help it out, some of students this year used buried dead wood to create ‘Stag Beetle Pits’ on the Writtle College estate.

I see there is more rough weather to come but, as far as nature is concerned, it might not all be bad news."

Writtle Wildlife Watch (October 2013)

‘Delicious autumn!’ said George Eliot and with the leaves now turning to golds and reds after a blazing summer, we probably all agree with her.

But winter brings its own rewards and we are all now on the lookout for the arrival of winter thrushes on our College estate. For the past seven years the Writtle Conservation staff and students have been doing their own little bit of ‘citizen science’ by monitoring the first occurrence of various seasonal indicators, such as the first Red-tailed Bumblebee and first House Martin of spring.

So, looking back, did spring arrive early or late this year? Well, quite late actually! This graph shows when the House Martins have arrived at Writtle College over the last few years. The number of the left hand axis is the so-called Julian Day i.e. the higher the number, the later the birds arrived. So we can see that for the past two years, our House Martins have delayed their arrival, perhaps due to colder conditions hanging on longer into the year.

In autumn however, we look to the north for the first Redwings and Fieldfares. These birds will be arriving any day now and if you see any on the Writtle College estate, please join in our citizen science experiment and tell us which one of the two species it was, how many you saw, when and where.

Writtle Wildlife Watch (September 2013)

September is a month for both our ever-faithful resident birds and for those just passing through on migration to other countries. The most stylish bird at the College this month was undoubtedly a Wheatear visiting Writtle on its way to sub-Saharan Africa. This elegant little bird stayed long enough to be snapped.

The College’s new-ish reservoir continues to attract many waterfowl but we also managed to bring in a small group of Grey Wagtails (of all the British wagtail species, this is the one with the longest tail).

And for years people in Essex have wondered why we never found Buzzards in our county! Well, we now have plenty of them and two were seen soaring over our farm late in the month. Not just a big brown bird, but a clever raptor which has hugely expanded its range in recent years. And one of our longest-lived as well – the oldest wild bird on record reached 26 years, 6 months and 26 days!
