In grassy woodland uphill / northeast of high conservation site (Wildflower patch 1). Discovered during follow up spraying of Serrated tussock. A patch of about 90square meters mono-culture with some out-layers. Too many tussocks for manual removal; I began to spray about half of the 90m2 patch but run out of herbicide. Mapped with Field Maps Untreated Weeds 2024/25.
