Piri-Piri Burr
Piri-Piri Burr / acaena novae-zelandiae. Suffolk. 28/06/18.
A close-up view of Piri-Piri Burr, a non-native problematic plant in the UK :-
*highly invasive
*widespread from S.England to S.Scotland
*favours coastal areas like dunes, sandy heathland/fields
*spreading inland increasingly
*forms dense mats smothering native plants
*has sharp, backward pointing barbs
*barbs attach easily to animal fur and bird feathers
*poses a serious threat to wildlife/threatened UK flora
*proven cases of injury or death of bird species
BEST VIEWED LARGE in order to see detail of the formidable white barbs on each flowerhead. A highly efficient method of seed dispersal by animals and birds......but often at an appalling cost to unsuspecting victims.
