Not really woodWORKING as such, but wondered if anyone on here had ideas to explain a rather strange site (deliberate spelling!). On the open hill up above Stonehaven, altitude about 200m, there are two stonewalled enclosures each about 20m square. Inside the enclosures are some 8 to a dozen overmature laburnum trees. Guessing they are 70-100 years old. But WHY would anyone plant laburnum in such a situation? They are toxic, or certainly unpalatable, to livestock as well as humans and the site is too isolated for them to be there for decoration. Wouldn't think there could ever have been enough demand for the timber to justify planting, especially somewhere inaccessible. Any thoughts?
