I belong to a group of crazy people who goes into a national park to remove environmental weeds. We cover an area slightly over 1,000 hectares. Weeds spread into the park from the surrounding suburban gardens, from abandoned house sites within the park, and from illegal rubbish dumping.
Weeds spreading from surrounding suburbs into the national park is a constant source of annoyance to us. The most invasive is a tree called Pittosporum undulatum, or sweet pittosporum, an Australian native prized for its sweet-smelling flowers and shady habit. BUT it does not belong in my local national park!
The local city council does offer cash payments for removal of weed trees, but there is very little publicity about it. Apathy and inaction abound. It’s heart-breaking to spend years removing pittosporum trees from the national park, only to find them growing profusely along the streets in my neighbourhood.
I think it’s time for a concerted campaign to rid the suburbs surrounding the national park of this highly invasive weed. Any ideas, anyone?
