Carter-Robb, said: “The map is shocking. It makes the reality impossible to ignore.
“This is not theoretical, without action we will lose our red squirrels.”
She said the “urgent actions that need to be brought together” were “fragmented” and “we are simply managing decline”.
The campaign called for a national plan to humanely manage grey squirrel populations and urgent investment in squirrelpox vaccine development.
It also wants support for fertility control research and deployment, and protection and enforcement of red squirrel habitat.
“We need government, conservation bodies, landowners, scientists and campaigners around the same table. The tools exist or are being developed.
“What is missing is coordination, funding and urgency,” Carter-Robb added.
The organisation suggested that while it was illegal to kill red squirrels, their habitats were being destroyed.
