Data of the repasturisation experiment: Phase 1 - Bracken control

Dataset ID:	446
Last updated:	2012-09-26
Dataset creators:	Kristin Roos Erwin Beck
Contact:	Kristin Roos
Temporal coverage:	2004-12-01 00:00:00 - 2007-12-25 00:00:00 - time zone: -5
Geographic coverage:	Llashipa site
Abstract:	Conclusion of the control experiment: -Spraying ... Abstract: Conclusion of the control experiment: -Spraying with Combo is the most efficient, low cost- and least manpower-requiring treatment. -On the other hand, the commonly used concentrations of this herbicide resulted in high mortality rates of all other components of the vegetation. -Half of the application rate of Combo in combination with cutting reduces the impact on other vegetation dramatically, but is still highly efficient with respect to bracken. -Black-foil & cutting, or cutting alone proved as the best method for bracken control if herbicides are not allowed and other vegetation should be preserved.
