Banham Zoo Banham Zoo News

If
Had a great visit today. Pretty much everything showed itself, including a couple of the wolf pups.

Penguin area remains closed due to Avian Flu, as does the Flamingo walk in area.
The Water Buffalo have returned to Watatunga, the sign says they have exciting plans for the paddock.
A lot of the species signage has been replaced with a new style, and there is a new map with the zoo split up into zones relating to the types of animals held or the location in the zoo, plus a miscellaneous zone. Every zone has a sign with a map of that zone and how it relates to surrounding zones. I have a put a copy in the media gallery:

Banham Zoo New Map - ZooChat
If my inference from the map is correct, their enclosure is being temporarily occupied by the zebu?
 
The Zebu are in the farm barn so that part of the map appears to be incorrect/out of date
Either that or they’re yet to move them. Thank you, I thought it odd that they’d put a “coming soon” sign in an occupied enclosure. Hoping they take advantage of that paddock’s size and bring in another large ungulate species.
 
News that Kash the Amur tiger will be moving to a new collection.

“We wanted to let you know that Kash, our beloved young Amur tiger, will soon be moving to a new home in Denmark as part of the international breeding programme (EEP).

He’ll be joining female tiger Layla, from Highland Wildlife Park in Scotland, as they begin an exciting new chapter together at Knuthenborg Safari Park.”

I've only just noticed something rather interesting on the page of Banham Zoo's conservation programmes - they are, in partnership with Natural England, establishing a breeding programme that aims to reintroduce the large copper butterfly back to Norfolk. The species became extinct there in 1851.

The page mentions that there are already 150 caterpillars hibernating on-site (the hibernating part makes me wonder if this information has been available since winter, and I just hadn't noticed it yet), which will be released after they have been studied post-emergence.

I would assume that they are not the only zoo involved - Hamerton Zoo's new website mentions the species as an invertebrate housed at the collection, but has no further information.

The Large Copper is extinct in the UK and was last seen in Bottisham in Cambridgeshire in 1851 - and not Norfolk as stated.

The Dutch race was introduced to Woodwalton Fen just a few miles from Hamerton from 1969 to 1973 in a project undertaken by the Monks Wood Research Station which was just down the road from the zoo.
The species is now formally extinct and cannot be released legally. No release programme has been approved.
If caterpillars are hibernating, the news must be old. They would be pupating or growing larvae at this time of year.

Hamerton's new guide book gives more detail of their work. They have been breeding this butterfly for some time, seeing the full life cycle over many generations (1500 individuals last year alone) along with cultivating its food plant the Great Water Dock. The species became extinct in the UK, and the last populations and reintroduction attempts took place just a few miles from Hamerton.

edit - as my time had expired.
The re-introduction of the Large Copper to Woodwalton Fen subsequently failed due to poor management of winter water levels on surrounding farmland, and the tiny size of the reserve which was not large enough to hold sufficient food-plant. There is a re-wilding project in-hand (which Hamerton raises funds for) called the Great Fen Project Home | The Great Fen aimed reinstating a large area of the Huntingdonshire Fens between Huntingdon and Peterborough, which will transform the prospects for an approved re-introduction of this beautiful butterfly. Current releases are illegal.
 
I believe the very last colony of the Large Copper was obliterated by the over-collection of Victorian butterfly collectors, who waded or even swam into the fenland reed beds where they were found, in order to claim their prize. Other species suffered similar treatment, notably the Purple Emperor, which survived, and the English Large Blue, which didn't.

Yes - absolutely. At the end they were worth a huge amount of money. The Dutch race (L.d.batavaus) locally know as the Giant Fire Butterfly, which the breeding programmes and past re-introduction attempts in Cambridgeshire/Huntingdonshire (one of which was not continually assisted and was successful for many decades) is identical in habits, feed requirements and appearance. There is debate as to whether the two should have ever been separated at all. A smaller darker sub-species of Copper with different breeding habits and habitat requirement is found across much of mainland Europe.
I am pretty sure the Large Blue has been re-introduced into Norfolk under a fully approved introduction scheme, although this was nothing to do with Banham Zoo.

I think it is another of the 'blues', the Silver Studded, that was recently re-introduced to Norfolk? To be fairer to the Victorian collectors I mentioned above, while they certainly didn't help in the demise of the Large Blue, I think it was actually the arrival of Myxomatosis that actually did for them. No rabbits meant longer grass growth, unsuitable for the field ant colonies that form a big part of their lifecycle.
 
I knew it was one of the blues, as I found out about the research needed before the programme was approved when looking into the Coppers - which as their story is quite local to me was my main area of interest, along with the local zoos involved. Sorry if I remember the wrong one.

Its interesting how a species like Silver Studded Blue needs a reintroduction in one part of the country- while in others e.g. on the Dorset heathlands at some sites there are myriads of them in a good year. Then on Portland (an island in name but not quite) there is another distinct subspecies which is adapted to a different habitat, calcareous grassland, though this subspecies is now in trouble I think. A lot of these butterflies seem to require meta-populations- a number of colonies spread around an area- in order to survive longterm. When these go, and only isolated colonies remain, they are in trouble. Perhaps how the Large Copper went too, apart from over-collection that is.
 
I'm sure you are right.
The fens around here were drained by Dutch technology driven by wind-pumps to produce the wonderful, ferlile, farmland that resulted, which in many cases was able to grow two crops each year. This was encouraged and subsidised by Governments whose first priority was to feed the population after the shortages and rationing of war-time.
The result was an unstable landscape that produced a huge amount of food. The erosion of the peat soils was dramatic, and is now especially noticeable at Holme Fen. Drainage caused changes in water tables of surrounding farmland, and heavy fragmentation and loss of habitat, and food plants. There is no doubt that habitat loss and fragmentation led to the loss of the re-introduced Large Copper populations, but contributing factors of poor winter flood control and a series of especially cold winters (much colder than we experience now) played large parts too. It can be argued with some justification that now these latter issues are solved by management and climate change(!) that this butterfly could re-establish itself in the current reserves.
BUT - the current small fen nature reserves at Monks Wood, Holme, Woodwalton and Whittlesey form the boundaries of this new Great Fen Project, and if this takes off in the way planned, the habitat fragmentation issue will be solved too. The Great Water Dock is very vigorous in the right conditions and easy to propagate, and Hamerton are growing this from seed, their own collected seed and plugs and older plants, alongside their work with the butterflies themselves. It is great to see such a small zoo with limited resources, but situated right on the edge of this historic and current area, get involved with such work; and it is hoped that the authorities support a re-introduction project when it is eventually proposed.

I have re-checked my notes and it was indeed the re-introduction of the Large Blue as I correctly remembered, though not in Norfolk.

For information - the UK Centre for Ecology & Hydrology encompasses the Institute of Terrestrial Ecology which ran the now closed Monks Wood Research Station referred to above. This was where the most recent Large Copper re-introduction work at near-by Woodwalton Fen was based, and where at the time my aunt was the secretary to its director, and where I visited its laboratories as a child - hence my on-going interest.

Sad news from the zoo today that their two South American fur seals have sadly died. This is a tragic loss, not least due to their species not being very well represented in UK collections and on a personal level, my thoughts are with their keepers and all those who knew them.

That's sad news. Toro born 2007 and Pablo 2009 I believe. Feel lucky to have seen them. A sad time for their old Keepers at Bristol and the Banham team and a shame the pool will be empty again.
