UK red squirrel populations have been on steady decline primarily due to foregin, grey squirrel invasion and insufficiencies of habitat and food sources.
Locations with high populations of red squirrels are shared with an abundance of pine martens, as they prey on the less nimble, foregin grey squirrels.
Grey squirrels struggling to prosper in these areas leave habitats and food sources open for red squirrels to thrive.
Marten populations have struggled in the UK because of declining red squirrel numbers, but their main threats are from human impact and poaching.
By integrating protective dens into domestic and public gardens, marten populations will be encouraged to grow.
With a strong external skeleton and a durable inner mesh that's grown over by its surrounding environment, the den is pegged into the ground to protect from both human impact and predators.
