    Pirri-pirri burr

    Pirri-pirri burr (Acaena novae-zelandiae) was originally introduced to Britain in a wool from New Zealand in 1901. More...

    The current distribution extends from the south coast of England to southern Scotland, particularly coastal areas in southern and north east England. Earlier records were mainly from coastal areas, but more recent records have been from inland and it was recently recorded in Leicestershire for the first time. 

    It prefers sand dunes but is also found on other sandy soils so it's unlikely to be found on clay soils. This species forms dense mats which can prevent native plants from establishing so it's important to monitor this invasive species so that action can be taken if necessary. Please keep your eyes open and if you think you see it, send us your records.
