Re: Scottish Forests

[original_aj]

The commercial driver is for monoculture fast growing softwood, hence why Scottish Forestry are using the grant schemes to leverage the inclusion of slower growing hardwoods and a variety of softwood types.

Trees are planted in rows here too, but that's because it's all done by machine now. Interesting (to me, anyway) cunning technique used to establish how many saplings have been planted in an area, and to what density: Put a stake in the ground in a randomly chosen point in the enormous and very uneven bit of land that's been planted. Attach a piece of string which is SQRT(20/PI) metres long - about 2.5m. Walk in a circle at the extent of the string counting how many saplings the string passes over. Repeat in a few different places until you are confident you have a consistent average. That's how many are in 20 square metres, multiply up to the size of the plantation. Saves trying to count a huge hillside, but only works until the saplings are too tall to get the string over them!
