Blean Woods

The latest update from Michael Walter:

Keeping databases seems to be a largely male fetish, and I have to admit to my fair share of them (databases and fetishes!), but they aren’t necessarily a sign of an obsessive compulsive disorder, and these rows and columns of figures can have their uses. So, for example, when the press says that this has been the wettest winter on record, I can turn to my weather statistics and…

The latest report from Michael Walter:

It seems to have been an extremely quiet period for most species that usually grace the reserve for at least part of the winter:  two small finches, the siskin and redpoll, are virtually non-existent, at least when I visit the wood;  and our two wintering thrushes – redwing and fieldfare – have been in extremely short supply, even in the orchards locally.  The mild weather…

The latest report from Michael Walter:

One of Blean Wood’s hidden gems is its heathland and, if you’ve visited the reserve, you’ll no doubt have followed a waymarked trail through a two-hectare heath.  Delightful though this is, especially in late summer when all the heather is in drowsy, honey-scented bloom, it is quite a small area.  A second heathy block, six times the size, is tucked away down the…

The British Trust for Ornithology annually mobilises thousands of volunteers to carry out counts in a variety of habitats as part of its Breeding Bird Survey, which monitors the health of the UK’s birds.  There is an inevitable time lag between the data being collected and the results published, but we now have the figures for 2018.  One interesting trend is that for nuthatch;  nationally, the population has been rising…

Unsurprisingly, given that it is our smallest bird, the goldcrest is easily overlooked, but there are actually quite a lot of them in the wood at the moment.  This is because, perhaps even more surprisingly, it is a partial migrant;  that is to say, some goldcrests remain here all year round, but others arrive here in autumn from Scandinavia, along with redwings and fieldfares, which are all escaping the harsh winter climate…

On Saturday 9th November (10am - 12pm) we will be hosting a 'Fungi Foray' at Blean Woods. Our local expert will lead a guided walk, delving into the hidden world of fungi! You will learn how to identify different species and separate the fact from the fiction. 

A magnifying glass will be handy, but is not mandatory.

BOOKING ESSENTIAL.

The latest report by Michael Walter:

Returning from a few days’ holiday in a glorious part of the Lake District in mid-September, I was quite surprised to note that the development of bracken’s autumn hues of yellow, orange and bronze were more advanced in Blean Woods than in the harsher climate of the exposed fells.  I can only assume that the much greater stress from heat and drought down in the soft south…

Last month I touched on the resurgence of the brimstone.  Well, now it’s official:  this has been the best season in 38 years of monitoring for this large and attractive butterfly, as the graph opposite shows indisputably.  The line is now approaching verticality, and it will be interesting to see if it starts to level off next year, as such a meteoric rise is unlikely to be sustained for much longer. 

With just seven…

Michael Walters' latest report:

In the plant world, the flowers with the greatest charisma, panache and pizzazz are undoubtedly the orchids.  While we can’t boast the dramatic epiphytic orchids that grow on trees in the tropics, there are about fifty species to be found on these islands, and we can even claim five of them at Blean Woods, although two (pyramidal and southern marsh) were only ever present as single…

Michael Walters' latest report:

Butterflies have been very much to the fore in recent weeks, starting with a minor invasion of painted ladies;  I qualify the influx as “minor” in order to distinguish it from the 2009 inundation that overwhelmed the countryside, when many millions of painted ladies reached our shores from north Africa.  This migration is achieved by a succession of generation hops – adults…

Michael Walters latest report:

Last month I mentioned the unwelcome find of a clump of Spanish bluebells in the wood;  I am therefore grateful to a reader who drew my attention to a post on the BBC website which suggested that the Spanish bluebell may itself be a hybrid, and is less fertile than our native bluebell, so unlikely to hybridise it out of existence.

A surprising sight on 27^th May was of a flock of about 80…

Michael's latest report:

Rewilding is very much in the news these days, with landowners allowing the whim of nature to dictate how a habitat develops, nudging to one side the contractors with chainsaws and bulldozers.  Instead the land managers are livestock, preferably old breeds of cattle, horses and pigs, which eat some of the developing scrub, create a seedbed by churning up the ground and stop ponds from disappearing…

Michael's latest report:

I was listening to Broadcasting House on Radio 4 this morning (14^th April);  a listener had sent in a nice recording of a blackbird singing in his garden and wondered if anyone could identify it for him.  The presenter was unwilling to stick his neck out, having been proved wrong on the programme too many times before, but his co-presenter hazarded a guess at robin.  Later, suggestions from listeners…

Guided walks

Sunday 5th May: Dawn Chorus (5:15 - 7:15am) - Those brave enough to face the early start will be treated to the sounds of nightingale, willow warbler, song thrush and many more! - FULLY BOOKED!

Saturday 8th…

Fieldfares have been more in evidence than usual this winter and, like almost everything at present except perhaps the weather, this may well be Brexit-related!  The Brexit connection is that UK fruit growers had become largely dependent on an annual influx of east Europeans to pick fruit but, amid all the uncertainty about the UK’s future relationship with Europe, that flow of workers has been drying up. Consequently…

My late-January bird count was undertaken on a chilly, misty morning.  The damp air drifted slowly through the tree canopy, mist tangling with the bare branches, and gathering into larger droplets, before finally falling to the ground.  Walking through the wood I heard the apparent sounds of rain on all sides, yet when I emerged onto an open ride, I was back into swirling mist, without the raindrops.  It was as if I had…

Following on from last month’s mention of mistle thrushes and their association with mistletoe, while in Cambridgeshire at Christmas I was interested to see mistletoe growing abundantly on roadside ornamental apple trees in a very suburban setting.  What particularly intrigued me was that several of the globes of greenery had established themselves on the slender trunks only a foot or two above the ground – with…

Michael Walter's latest report:

Approaching the reserve car park the other afternoon I was greeted by the dry rattling call of a mistle thrush.  Noticeably larger and greyer than blackbirds and song thrushes, they have the same penchant for fruit as their cousins at this time of year, and this bird was gorging on the berries of a hybrid whitebeam/rowan tree beside the car park.  The concept of a bird’s territory has…

Michael Walter's latest report:

It sometimes seems as though the wood is in a foreign country, so heavily has it been invaded by alien plants, from the larger sycamore, sweet chestnut and rhododendron right down to humbler species such as feverfew, New Zealand water stonecrop, Pyrenean cranesbill and stinking hellebore.  A fairly recent coloniser from gardens in Rough Common is the pheasant berry (Leycesteria formosa…

The latest report from Michael Walter:

My last routine task of each day is to go outside to take the maximum and minimum temperature readings. On the evening of 12^th October it was still a beautifully beguiling, sultry 20° at 10.15pm and a check the following morning showed that the temperature hadn’t dropped below 18.5°C during the night. With a slight mental shudder, I was instantly put in mind of the night almost…

Late summer has proved an extremely uninspiring end to the butterfly season.  Bread-and-butter species, such as gatekeeper, meadow brown and ringlet, appeared in only moderate numbers, but as they faded away in the second half of August the expected flush of colourful Nymphalid butterflies (peacock, red admiral, comma and the occasional small tortoiseshell) failed to materialise. 

The latest report from Michael Walter:

The territory maps have now been drawn up, so we can see how many birds of each species there were this spring, and compare the results to last year - and what dismal reading it makes!  Wren, nightingale, garden warbler and spotted flycatcher have all performed very poorly, and some others, while not far below the long-term average, have been present in much lower numbers than last…

The latest report from Michael Walter:

How much longer can it last? I have recorded no rain whatsoever since 7^th June, and that was only 2.8mm. The last significant rainfall was on 29^th May, nearly seven weeks ago, which is probably unprecedented in the 37 years that I’ve been keeping records here. Remarkably, most of the vegetation is standing up to the searing weather pretty well, although some of the birches are losing…

Regular visitors to Blean Woods will be aware that, while it may be famous for its nightingales and heath fritillaries, the same cannot be said for its floristic appeal. Yes, bluebells, wood anemones and primroses all occur here, but for the most part not as breathtaking displays. However, there is one plant which, while not drawing botanists from miles around, is quite a feature of the wood at this time of year, and…
