Integrated bracken control and vegetation restoration: ongoing assessment with follow-up treatments (old BD0507) - BD1209

Description
This study involves implementation of a 5-year system of integrated bracken control and re-establishment of appropriate vegetation. The project builds on existing experimental work, which examines effects of experimental treatments on subsequent vegetation development, together with monitoring of both rehabilitation experiments on previously sprayed areas, and bracken-front control experiments. The study will also investigate effects of conventional and novel follow-up treatments on vegetation development and impact of treatments on the bracken rhizome system. Existing experiments currently follow a split-plot design, while the follow-up treatments will be applied at one split level down and will include herbicide application (either by spot spraying from a knapsack or by means of a weed wiper), fertilizer application and grassland re-seeding. Rhizome biomass data will be collected in the autumn of 1998, since the 5 year treatment programme will have produced changes sufficient to produce good divergence between plots. Furthermore, the data produced will allow experimental results to be used as validation for existing models of bracken growth and vegetation development (BRACON and REBRA). These data will also be used to develop and test new statistical models, which will then be employed as predictors of the efficacy of bracken control and vegetation development.
