Hi there,

i am am very concerned about a small lake near where I live for the past 5 years and as long as I can remember it has been alive with spawn and tadpoles but this year absoulutlely  nothing.I looks neatly enough plenty of fish etc.I do recall last year seeing quite a few dead frogs in the long grass nearby.The place in question is Cotefield Resovoir in Bodicote near Banbury.

Can you help thro some light on this for me.

Many thanks,


almost impossible to say. time will tell whether they are delayed by a few weeks or whether there has been some local environmental change to account for the absence.
