High grade timber can be removed from forests with no disturbance to the infrastructure. Selected trees could be felled, timber converted into planking using modern light mobile band mills and the valuable wood carried out by mono-rail transport. Mono-rails only require a 2 metre wide passage. This is supported on hydraulic jacked support chairs every 4 to 6 metres. The only contact required with the forest floor. Industry could meet the demand for this system from proven technology. Butts on steep hillsides could be carried to the saw by high lead logging systems which have been in use for 100 years.
The mono-rail could be laid at a rate of 1kl per day easily. I worked with these systems which carried 2 tons of concrete using a 10hp engine 50 years ago.

Phil Pullinger, why would anyone take any notice ???
(Can you)  match the specialist knowledge and experience of the scientists, managers, and trained foresters who work in conjunction with competent engineers and trades people who make up the modern forest industry?
