Hieracium Sample Clauses

Hieracium. Hieracium can be controlled by converting the land to more intensive use, for example through activities such as cultivation, over-sowing, topdressing and/or irrigation. Where this is not an economic option, or where conservation objectives (A) or (B) above are the preferred land use, other strategies will be needed. In such cases, as noted above, it is accepted that Hieracium is likely to remain part of the conserved landscape to some degree. • Biological controls have been introduced and are expected, over time, to reduce the competitiveness of Hieracium. In addition, there is evidence that the taller species of Hieracium can be controlled by light grazing. Grazing may therefore be appropriate to achieve conservation objectives in specific locations, but it does not assist the control of the main species of Hieracium present in the Mackenzie, Hieracium pilosella.
