The abundance of trees that once existed here as part of the ancient Caledonian Forest helped the mussels survive by shading, and thus cooling, the River Dee and its tributaries. These lower temperatures increased the dissolved oxygen available to Atlantic salmon, in whose gills pearl mussel larvae live as they mature. But deforestation ran rampant here in the mid-19th Century, when Queen Victoria moved to Balmoral and made open, unforested estates fashionable. Trees further disappeared because of fuel needs during the two World War efforts.
