News of wildlife and other issues
Don't say I didn't warn ya!
There it was – gone. Just like the view from Aldersbrook Road, opposite the shops at the Parade, the view from the south side of the Shoulder of Mutton Pond will – I predict – go the same way.
On a visit on 21st April 2015 to what I think is one of the nicest locations in Wanstead Park – the south side of the Shoulder of Mutton pond looking across towards Wanstead – I realised just how much willow had grown up along the shore-line. Much more – and it won't take long – and in-leaf, the view will soon be all-but gone.
Just a few metres further on – on either side of the fence that separates the Park from the Park-lands – all the insect-favoured bramble scrub has been removed. All of it. Just like most has been removed from the other insect-favoured scrub near the top of the Glade, from just behind the Grotto, from what will be the bicycle/pedestrian Roding Valley Way at Whiskers Island, and of course- not scrub but herbs – annually by the east end of Perch Pond. And why was all the scrub and trees removed by Epping Forest Conservation Volunteers from the crater just south of the keeper's lodges. Surely that was only doing harm by acting as a nesting place for birds and a resting place for insects?
see here) others have been in there and changed things a bit. Desire-line paths have been blocked, particularly that which runs between a sward of Wood Anemones. Though this may have been done with the intention of enhancing those delicate flowers, I fear it will have the opposite effect, as the desire to use the path – and indeed to look at the flowers either side of it – may just encourage people to walk over them. There are signs this is already happening.One more. Chalet Wood is looking good right now with its becoming-famous bluebells. I do think the path-edging that I have been suggesting for years has been successful and most people who I speak top agree. There are aspects of the way it has been done that I am not fully happy with – too much scrub has been cut down on the east edge, for example. And since Gill and Alan James and myself – primarily – laid out its pattern in 2014 (
So – back to the Shoulder of Mutton and its willows. I mention that now like I mentioned the potential problems with Floating Pennywort in Perch Pond and New-Zealand Pygmyweed in Alexandra Lake years ago. Both those issues were ignored, now the problems are extreme. Something could be done about willow encroachment now, perhaps, but if not – well, don't say I didn't warn ya.

Bats of the Wanstead area - a status summary
by Tim Harris
A qualifier with these observations is that I typically record bats in our area on 6-8 evenings per season. Lots will inevitably be missed.
Daubenton’s Bat (Myotis daubentoni)
A regular species in small numbers over and around the lakes in Wanstead Park and probably in larger numbers at Hollow Pond although, ironically, not positively picked up on the two waterways transects along the River Roding in August 2013. In 2014 several individuals were detected over Heronry Lake on 30/7 and over Perch Pond on 31/7 and 4/9 (Wren bat evenings).
Serotine (Eptesicus serotinus)
1 near Whiskers Island on 22/8/2013 was detected while on a waterways bat transect for BCT (TH/SP).
Common Noctule (Nyctalus noctula)
A species regularly recorded in small numbers over Wanstead Park, Wanstead Flats and Hollow Pond. Alexandra Lake seems to be a popular foraging area for the species in midsummer, when individuals can be seen at or even just before sunset, and also just before dawn. I have never seen more than 8 together in our area and most observations are of singles.
Leisler’s Bat (Nyctalus leisleri)
1 was detected near Perch Pond on the evening of 26/7/2009 and there was a probable there on the evening of 17/7/2009 (PF/TH).
Common Pipistrelle (Pipistrellus pipistrellus)
A common species in summer in Wanstead Park, Wanstead Flats, Hollow Pond etc. Favoured foraging areas include all the waters in Wanstead Park, and Alexandra Lake. My feeling is that the species may be a little less common than Soprano Pipistrelle, which seems to emerge a little earlier in the evening. In 2014 good numbers foraged on suitable evenings around and over Heronry Lake and Perch Pond.
Soprano Pipistrelle (Pipistrellus pygmaeus)
Common locally in Wanstead Park, Wanstead Flats, Hollow Pond etc. Favoured foraging areas include all the waters in Wanstead Park and Alexandra Lake. My feeling is that the species may be a little more common than Common Pipistrelle in our area, and it seems to emerge a little earlier in the evening. In 2014, good numbers foraged on suitable evenings over and around Heronry Lake and Perch Pond. This is the species that most often come over my garden in Belgrave Road.
Nathusius’ Pipistrelle (Pipistrellus nathusii)
Two transects specifically for this species were conducted for the BCT in September 2013, around Heronry Lake. On the second of these transects on 22/9/2013, recordings were made and 1 individual was identified (TH/MH). This species is probably under-recorded.
Brown Long-eared Bat (Plecotus auritus)
Never recorded by me locally, but it probably should be around. This is a harder species to pick up due to its different feeding technique and quiet echolocation calls. Worthy of further investigation!

Mammal Survey in Aldersbrook Exchange Lands
On Friday 29th August 2014, Darren Tansley, Water for Wildlife Officer for the Essex Wildlife Trust, and Tim Harris, from the Wren Wildlife and Conservation Group, set out 30 small mammal traps in the Aldersbrook Exchange Lands. This is the site of the old Redbridge Southern Sewage Works and now is mostly part of Epping Forest, with a central area belonging to Thames Water Authority. (for more information on the site, click here)
The traps used were Longworth Traps, which are designed to trap small mammals live so that they may be examined. Even when the trap is sprung there is a small hole for very small mammals to escape; Shrews need to eat continually, or they will die.
This operation was on behalf of our local Wren Wildlife and Conservation Group, and the following morning Darren gave ten Wren Group members some fascinating insights into the behaviour of voles, mice and shrews. The catch was four Wood Mice (2 males, 1 female and 1 that escaped before being sexed!) and a single Field Vole. There was also plenty of evidence of shrew activity, with both Common Shrew and Pygmy Shrew likely to be on site.
Darren raised a number of possibilities regarding the Exchange Lands. He thought there was a reasonable chance of Harvest Mice being present on the site. Apparently this species can colonise in only a few years of changed habitat status, and the site has been changing since it was closed as a sewage works in 1978 and later redeveloped to become part of Epping Forest in the 1990s. He also thought the Roding margins were worth checking for Water Shrews. And then, of course, there are Water Voles and Otters to look out for. Water Voles used to be a common inhabitant of the Roding adjacent to this site as well as through Wanstead Park. They became scarce by the early 1990s, although one was seen in 1998 and again in mid July, 2004. Since then, I have not heard of any being present. This may well be due to the presence of American Mink. Otters, however, are now not far upstream, and there have been one or two unconfirmed reports of sighting in the Roding by Wanstead Park, so surely it is only a matter of time?

Ringlets in Wanstead Park – and in Aldersbrook Exchange Lands
Last year (2013) the first Ringlet butterfly to be recorded in the area was spotted by Kathy Hartnett and myself just to the east of the Shoulder of Mutton Pond in Wanstead Park. (see article here)
This year, on July 9th, Jennifer Charter was walking her dog when she saw what she thought may have been a Ringlet in exactly the same location, on the same patch of Rosebay Willowherb. She told me of this, but said that she couldn't be positive about the identification.
Today, though (11th July), again while walking Grace, a butterfly unexpectedly flew past her in dullish weather, landed on a small oak and waited while she photographed it. It was most certainly a Ringlet, and a little further east than the other sightings, but it seems that they are in that area.
Another local wildlife-enthusiast – Rose Stephens – saw what she thought may have been a Ringlet on Wanstead Flats yesterday (10th). It seems she posted the information on Facebook, but I don't use that, so received the information second-hand. I looked at her photograph, but am not convinced it is other than the much more likely Meadow Brown. It would have been lovely if it were a Ringlet, but the butterfly is not typically found in open areas such as grassland or heathland, preferring damp and sheltered places.
This damp and sheltered habitat is more in line with where it was seen in Wanstead Park last year and this, and on 13th July during a Wren Group walk in the Aldersbrook Exchange Lands (the Old Sewage Works site) Mark Thomas, spotted a Ringlet amongst vegetation near the pylon towards the cemetery end. Then Kathy Hartnett found another on the lower path beside the Roding.
It was great news that we have Ringlets in the Park, and it seems that they are present further afield in our area too. This brings the total number of butterfly species in our area to 28.
