Relocating a well established frog colony
Long story short we have an old 1980's fibreglass pond smack in the middle of our garden. It's teeming with frogs (12 adults counted last summer, and hundreds of spawn) and recently active again as they kick into life to breed.
The issue is the area immediately surrounding it is being redesigned, so the shelter the pond was afforded has gone - and I know for a fact they've been preyed upon by something (I suspect a heron from the local canal). Secondarily, I have a 1yr old who by this summer will likely want to have a toddle around and explore the garden. So, the pond has to go.
I'm reluctant to disturb the frogs, and really don't want to harm them in any way. I'd actually consider moving them to another part of the garden temporarily until a more suitable time to rehome them.
Can anyone offer advice on a) re-siting them into a new area without causing harm and b) the best time of year to make a permanent move?
All the best,
