Have just joined the group to try and get someone to top up the water in the wildlife pond, if anyone knows who does this then can you please contact them and let them know that the goldfish there are struggling in about a bucket of water with nowhere to escape to.

Park ranger tells me it is FOSAP who look after it so will someone please get it filled.  A whole week of rain would probably not do it, someone with access to a tap needs to sort it out.

Can someone post to let me know what's happening about it.

Thank you, Zenia,  for contacting us about the pond water level.

We are aware of the problem and we are looking at ways to get some water into the pond soon.

Jo

Yes sir. Right away sir.

(and those bloody goldfish shouldn't be there anyway!) 

mickey sorted it out

Hi Des

Can you clarify your reply for me? Do you think perhaps I should not have brought it to the attention of Friends?  Must say I totally agree it's not the place for goldfish, or anything else 'introduced'.

Zenia

Hi Zenia,

The pond  level is now fine, thanks, I believe to Mickey our resident park keeper whose work is invaluable in the park.

No, you were right to contact FoSAP about your concern over the water level. However, fluctuating (and in dry summer months, often low water levels) are frequently experienced by pond organisms and most have evolved strategies to cope with and survive the stress of such conditions. Possibly even goldfish. However, these are not a native species and FoSAP wild life group were (and are) not happy with the fact that they were introduced without permission into our pond and furthermore, that they are breeding too successfully!

It may well be that the expanding population of goldfish will be checked and reduced by low water levels and although it may seem a bit 'cruel' to allow natural selection to operate by this means, it is hopefully the most efficient way of keeping their numbers down and preventing them from predating too seriously on the native invertebrate fauna of the pond, such as damsel and dragonfly larvae, whose presence in the pond is much more desirable.

Topping up ponds with tapwater is usually not recommended as it is high in nitrates and leads to excessive growth of algae. Incidentally the best ponds for amphibians are those that dry up every 10 years or so, as they are then fish-free. Otherwise the fish gobble up all the tadpoles!

With present autumn rains, this topic is, I suppose, all water under the bridge now - or evaporated into the air?! But your point about tap water is valid. I would be more concerned at the insidious effects of its chlorine content. Vertebrates would be unlikely to be affected by this, but even the low levels of chlorine in tap water are likely to cause considerable damage to the micro-organism flora and fauna populations and consequently on small invertebrates such as copepods and cladocerans in the next link up the food chain, that depend on these. But of course we aren't aware of these probable repercussions on the pond habitat at the microscopic level.

The trouble is that our pond is likely to dry out more frequently than once every 10 years! Indeed, three of us are now in the process of  trying to prevent this happening again next year by weeding out the reeds (Phragmites) which have so aggressively taken over the pond this season. If this was not done, the pond next year would be more a reed swamp, with little or no open water surviving. And the following year doesn't bear thinking about!

If you or anyone else would like to help out in this essential pond maintenance, please get in touch via the website to sort out a suitable date in the near future. We have had three (weekend) sessions on the reeds so far, and we think one or possibly two more sessions should keep the reeds at bay for another year.
