Spring has finally sprung and there is so much evidence of that on the reserve at the moment. From singing summer migrants to emerging summer wild flowers, there is so much to see. Bring your family to one of the family events and then spend the rest of the day exploring.
Saturday 26th May 10am - 12noon - Wild art and craft
Nature can provide so much inspiration so we will be out on the nature trail looking firstly at patterns and colours and how wildlife makes it's own nature gallery before we start work on our own. We will collect natural materials and we will be making our own masterpiece and creating Tophill Low's first natural art gallery for all to enjoy. Bring appropriate clothing for the ever changing British weather and of course a picnic for afterwards. The event is FREE with standard entry. Please call 01377 270690 to book.
Tuesday 29th May 2 - 4pm - Springwatch at Tophill Low
There are plenty of wildlife stories to tell at Tophill Low so with a bit of research and fact finding we can produce our own version of Springwatch and film it too! We will start by looking around the reserve to make sure we know all about our chosen animal, finding evidence about its life on the reserve. Once we know our "story" then we will put together a script and start filming! Budding presenters here is your chance to star. The event is FREE with standard entry. Please call 01377 270690 to book.

Regardless of the fox we had a great success last weekend with our long term mink issue having not caught any since last February. We use the 'GCT mink raft' design which rely on the natural inquisitiveness of the animals to investigate holes to lure them into a live capture trap. Baiting has never been successful and we have tried many types over the years. Mink are predators rather than scavengers and therefore don't seem to be attracted to carrion (even though they do live on their own cached stores of dismembered prey in their home range of North America during winter). We reckon the mink at Tophill had become trap shy - having possibly escaped in the past from a trap / or just had been selectively bred through our persecution to be naturally wary. In the end we utilised some used pet rodent bedding and droppings pushed into each trap - the strong smell of potential prey was seemingly irresistible and the next day we caught a female.
Removing a wild animal that is just trying to make an honest living (here due to human stupidity in the first place) is never a nice job. However this animal was heavily scarred on the back of the neck from mating - and not recently so quite likely is an experienced breeder from last year. As catches go this is top drawer, and at this time of year the hundreds of native birds and mammals this has saved this summer is undeniable. And predictably the very next morning the male was caught in the same trap. Our experiences are that mink tend to sit on a territory during summer so re-colonising is unlikely until this years young strike out in autumn. Potentially this may have had as big an impact as the fox fence this year. So a good start to spring (unless you're a mink).
Hopefully these guys may stand a chance for the first time in a while - Neil Murray:
Monday 19th - open as normal
Tuesday - upper half of car park being surfaced - lower open as normal
Wednesday - Lower half of car park being surfaced - expect disruption to parking
Thursday - Open as normal

Also - New Membership permits; I very much hope from Saturday the 24th.
A few more wintering specialities - brambling at the feeders still - Roy Lyon:

Martin's gull watching exploits you'll be aware that a glaucous gull is an irregular visitor to the reservoirs - usually only glimpsed in grainy half light amongst thousands of other gulls through gritted teeth and a biting westerly. This 1st going into 2nd year has found the reservoir to its liking now for two months - Brian Colley:
As such it seems only fitting that the new membership cards for Tophill Low are of last years Kingfishers. The winning picture (voted by 25 Yorkshire Water office staff on image merit alone) was kingfisher by Stuart Allen:
Memberships are due from April 1st; please note that new cards are not available just yet - they will be available from later this month - I'll put an announcement out when that is the case.
As ever there are thousands of brilliant images to choose from at Tophill Low - I choose an initial selection that will work for me as a composition with neutral backgrounds for text etc - here were the other contenders:
Cuckoo - Don Davis:
Amazingly the operative managed to get a machine to the rear of south marsh west and clean the whole outlet dyke out and all around the islands - and then all the way along the west and northern shores of the marsh:
here). I apologise for the disturbance - but we want to get it finished and working for these species this year.
Unfortunately we're still working on mink trapping at present with still no takes. We clearly have a very cunning adversary. A tantalising glimpse of a mustelid in the otter holt camera at North Marsh nearly popped the champagne - until it woke up and was a mink...
An added job that has been long in the offing was to clean some areas of East Pond out and try and find out why its been losing water since 2015. Hopefully a success on both fronts:
They may look a bit beaten up now - but being willow they'll have 8 feet on them in a year or two - and allow the hawthorn to get away in the meantime. Unfortunately there is no magic spell which can be woven to get them to the required shape overnight. Like much of the habitat work we do at Tophill we often have to go back to a sub-optimal point from a post optimal - to reach the optimal...
The biggest challenge for the volunteer wardens and I is dealing with the public. People don't read signs. If they do, they ignore them if they don't like them; Then in most cases become aggressive and mouthy if challenged directly courteously or curtly depending on the individual - the result rarely differs. The layout at Tophill Low has been a big problem for a good while and has consistently fed this conflict leading to poor visitor experience and in some cases direct harm to the wildlife or significant confrontations with staff.
One of the biggest conflict areas is the disjointed southern half of the reserve. Prior to 2000 all access to the reserve was undertaken by turning left at the water works main gates - passing the former western entry to the residential properties and entering the car park from D reservoir from which it was all pedestrianised. On expansion of the water works the current circuitous route right at the gate around the lagoons and water works was installed. This has engineered in a lot of problems repeating the same conflicts time and again.
Porosity of the reserve. From the main WTW gates there have been five points to enter the reserve in current or old setups - and indeed the whole of the O reservoir without ever passing the ticket point. The income is important as it helps to run the reserve day to day. It is annoying when people don't want to contribute to the upkeep of the reserve (Listen closely to the conversation in the background of the amur falcon video here...by no means an exception). But ticketing also maintains the exclusivity of the reserve for visitors coming to enjoy wildlife. People walking dogs around the O Reservoir is a regular issue. There is no ambiguity in the signage anymore so it is people simply ignoring the signs. Generally this is cheeky curiosity, but ground nesting birds, the roe deer people delight in seeing at the moment, or our grazing stock on loan can't differentiate this if a dog is coming after them. This can either be the genuine "he's never chased anything before - he wouldn't harm it if he caught it" panting owner running after it, to the dedicated deer poacher running lurchers. This also puts us at odds with the residential properties whom own dogs. Its very difficult to explain to a visitor they can't bring their dog whilst someone is walking theirs along the road in the background. Currently there is an agreement in place that the householders do not walk their dogs along the road in public open hours, but this relies upon goodwill and solicitor back up which is far from ideal. The problem is that the lagoon road route is both an access for the private properties and the approach to the reserve, and yet also inside the reserve. If this could be separated out it would save a lot of argument and ambiguity. Removing the gate from the car park to D res directly has overnight cured much of this same conflict in the car park as part of the reception hide project - it would be great to do the same for O.
Poaching and antisocial behaviour. We've had odd incidences of poaching and obvious beaters seeking to dislodge wildfowl for nearby shooters, but perhaps most disturbing a pick up with three guys with shotguns opening up on birds on the SSSI a couple of years back. We've also thrown youths out of the lagoon hides smoking cannabis, cleared up the beer cans etc. Its no coincidence that the dumped terrapin of south lagoon was outside the first hide you pull up outside in a car. Quite often the first defence of people intercepted is 'its public land I can do what I want’ - because they have not entered a physical boundary they do not believe or respect they are on private land. If we could seal off O res and the lagoons from this access and force everyone past the ticket machine and well placed warden staff it would solve a lot of ills at source and potentially vandalism or damage in future. We've been fortunate with Tophill's remote location - but increasing human population everywhere means this is not going to go away - only grow.
Safety. The several pedestrian road crossings aren't ideal, either for youngsters unaware, or dare I say the older birder too focussed on the siskin above. Frequently visitors walk along the road rather than the pavement with the blind corners and the threat of oncoming delivery vehicles. At Yorkshire Water we have to take safety very seriously. If we can engineer out risk - we will. There's also no accounting for stupidity. By routing people via the reception hide they can hopefully absorb the safety signage or be told it directly. Such as the group bringing their dinghy to go in the res the other year, the guy dissuaded whilst stripping off and readying his towel for a swim on in O res last summer, the fishermen on D res:
Visitor experience. Tophill is a very confusing site for humans. Someone once advised me that 'you can't force them somewhere they don't want to go. You need to make them think that's where they want to go.' When queried many visitors go north - not because it’s better for wildlife necessarily - but in many cases simply because its counterintuitive to walk back the way you just drove in. This was a key problem with the old wildlife centre. The new reception hide works really well for northbound traffic as everyone passes the warden staff, sightings books and site maps and can work out how to get the best out of their day. The O res and southern route at present bypasses all of this, and sidelines warden staff helping visitors and protecting wildlife. People in future can make a conscious decision whether to go north or south - rather than just being railroaded north or sneaking south.
So the goal is to link the north lagoon path (hence all the swamp walk and new path spur last year) with the O res. This will mean one point of entry, one point of exit - all past the reception hide. O reservoir and the lagoons will no longer be accessible from the access road and will be gated off for pedestrian access. The access road will become just that - the access road. This was to be a gradual process as time and money allowed - but we have been given the opportunity to progress it this year.
The only potential downside of this is disturbance to birds using the lagoons if not done sensitively. Whilst it’s fair to say they haven’t been in peak form for many years the recent works of 2015 have given them a new lease of life. A lot of work and sacrifice went into this so I certainly don’t want to impact on them. We’ve managed to carefully tuck a route against the hedge largely well under cover and out of sight of birds on the lagoon - particularly at the critical wader season when the trees are fully leaved:
The main and pressing section to mask of is immediately adjacent to the North Lagoon hide.
So that's one big element undertaken this winter. Now for another...
Passing the South Lagoon Inlet hide you may have noticed it is no longer there (after being closed for sometime):
Whilst the hides themselves were well built (often by folks still visiting today) the budget was not made available 30 years ago to provide treated timber. In the air this tends to be OK - but the issue is at ground level were the rot sets in. We've already undertaken several hide repair or replacement projects - North Marsh was replaced in 2009:
This was ultimately a significant factor in the old car park hide demise. We suspected there was some rot in the legs but were a bit horrified when we tried to salvage what were considered solid telegraph poles which turned out to be 90% pulp wood:
This prompted an in depth look at the remaining stilt hides. East hide surprisingly given its exposed location received a clean bill of health:
South marsh west 'L' hide was found to have some rotten supports (We undertook replacement of two legs 4 years ago). So we've had the professionals in underpinning it elsewhere - all that it is readily visible to the keen eyed is this new section of floor:
However the north hide at the top of the D reservoir was found to have six of its 8 legs on their way out:
Coupled with a rotten stair case which needs complete replacement:
Whilst the actual hide is sound at the top, replacing the supports is no simple or DIY task for the volunteers. Whilst work can be done on the cheap and 'by my mate...' we cannot do so within Yorkshire Water - it needs safety qualified and vetted companies working upon it. So we had a serious look at costings and to completely underpin and repair the structure was significant. So significant in fact it is cheaper to start again with a new structure outright. Unfortunately it is the end of the line for this hide and the bat boxes were relocated last year in expectance. I can fully understand that its a shame and many happy memories and recollections go with these structures - but alas I am tasked with making the call on when their time is due.
Replacement is simple enough. However this prompts the question; Is it worth replacing this hide like for like? Asking around regulars on the reserve the general view is that the hide is occasionally handy for a bird at the north of the reservoir, but it is seldom used for prolonged observation as quite simply it looks straight into the sun all day long and in any kind of sunlight the birds are unobservable. Though its fair to say it does deliver the best sunset shots on site:
With its substantially set back position it also loses a lot of view under the walls. Quite often the route march to get that close up of a grebe sp. is fruitless as its disappeared below the wall. Some favour it for barn owl photography or passerine watching behind the hide in better light, but its a lot of structure for the purpose. Perhaps its most regular usage is simply as a half way stop off and shelter on the walk around the D res.
In many case the purpose of this hide could be much better met by a simple low level screen much like the O reservoir - and this is the way we hope to go here. Better for identifying problematic 'top end of res' birds and better for photography.
However this means we effectively lose a 'proper' hide at Tophill. Yorkshire Water have kindly given us the option to think about keeping the same number - but considering a different location, and also the thought of doing something a bit 'out there' for the serious enthusiast. Initially the obvious thought was simply another better placed tower hide perhaps on the western side of the D res in better light. I have no doubt it would be stoically welcomed as 'a good solid proper birder's hide.' The reality is that it again would be woefully underused, and not offer any new benefit over the reception and east hides on the res.
So we've gone back to the drawing board and considered which hides are packed and favoured at the reserve. And generally it is those with close in and particularly photographic opportunities. North Marsh and Hempholme have both been standing room only much of summer. If we could do something that replicated and bettered these it is sure to be a hit. After a lot of consultation with regulars and volunteers we have centred upon the installation of a photographic hide on South Marsh East overlooking 'sandpiper bay' where the lagoon outfall delta's and hold the attention of sandpipers, egrets and kingfishers close in.
Since the construction of the sandpiper bay its become obvious SME 1 hide is a little mis-orientated now with cameras competing to try and shoot through the extreme left flap:
Initially thoughts were a dog leg on the existing hide (which is remaining indefinitely as its on a concrete slab). But instead we've looked back at previous Tophill hides and gone for something low level. As some of you perhaps notice on the drive in to Tophill there is what appears to be a piece of plywood sluice board banged into south lagoon:
This is in fact the first photographic hide at Tophill - overlooking exactly the same habitat and waters we are proposing further down. Siltation, vegetation and site changes meant it was long since abandoned. But we are looking at v.2 further down the site...
So full details will follow in due course... Whether it will get installed in time for this breeding season is still up in the air at the moment - but it hopefully explains some of the workings present:
And finally back up to the car park for a finishing flourish... We will be retarmacing the broken and worn surface on the week commencing the 19th of March Monday to Friday So an advance warning; the car park to Tophill Low Will be closed for the duration. Currently we're working on alternative parking options - but if you can tailor your visits around this it will certainly help to ease pressure on the limited space we will have.
If I'm still standing at the end of all this - I hope I and everyone else can look forward to an excellent breeding season - with the oystercatchers already present and correct - Sue Murray:
And the roe deer readying for the rut - Josh Harrison
So thanks to everyone for their patience - not just for this winter bit the last three. A huge amount of work has been undertaken; and whilst at times its difficult to see the purpose beyond all the mud and modifications, I see this as being the close out of the biggest spell of investment in the future of the reserve since its opening in 1993. The crucial thing I hope everyone can recognise is that after a period of uncertainty on the future a few years ago, it can now progress firmly established as a nature reserve with the best habitats for wildlife and the best facilities for people keen to experience it.
Tophill is an amazing place - the diversity of wildlife is perhaps only topped by the diversity of dedicated people who visit and volunteer on it. It is my hope going forward from this summer we can explore these to the full as there is a wealth of knowledge to tap and wildlife to find. And hopefully this blog will return to a more wildlife orientated slant than the current construction journal! I can get back to the things that float my boat like this aerial crown-gall taken by Doug Fairweather:
He reports it is a gall caused by an agent on willow trees. Normally these agents are wasps or fungi - but in this case it is a bacterium and growing on a pollard we cut 5 years ago. Proof as ever there is never nothing to see and never nothing left to learn...
