fireweed

Good follow-on stuff John. A valuable way of monitoring, for us all to see.
Was the bracken sprayed?

Bracken

Hi derek,

No, we didn't spray the Bracken on this occasion; once we had raked last season's dead material from the site, we trampled or cut down any new growth on each subsequent visit. Unfortunately, it has only been done at monthly intervals so far - other employment has "got in the way" - but to date, we seem to have significantly restricted new growth within the control area, whilst outside that area it has grown aggressively. We hope, as more enthusiastic manpower becomes available to "grow" the control area and then to plant native trees and other flora - but we shall see.

dieback

Yes, many years ago, I 'bossed' 8 plots of experiments (with student labour). Some chemicals, digging (rotovating), cutting, liming and trampling. Trampling kept it down but produced very gnarly and tough remnants - back with a vengeance the next year. Liming worked for the following year.
I once saw a whole untreated dieback - some sort of invert creature, might you about that? I never did find out.
