Donal Hickey: Red squirrel at risk

More tree-planting would help the survival of our native red squirrel, which is under serious threat from the American grey squirrel, a new study suggests. Evidence shows that the pine marten, as predator, is helping to control the population of greys.

The problem is, however, that the greys are often found in parkland areas of towns and cities which distances them from the pine marten, a forest specialist which prefers to stay well away from people and urban areas.
