Catstocks Wood A mature wood on this site was felled in 1961 and replanted. This is fertile ground which will grow top-class broad-leaved trees.There is a 'nurse' crop of Thuja and Norway spruce, but in time only the final crop of oak, beech and ash will remain. Note the belt of scrub purposely left on the lakeshore as a haven for wildlife. This has been designated as a Site of Special Scientific Interest. Bassenthwaite Lake is a National Nature Reserve.
