Many of the weedy species that are invading and damaging our natural areas are ornamental plants that have ‘jumped the fence’ from gardens and gone wild. It costs councils, government departments and private landowners millions of dollars, and volunteers and community groups thousands of unpaid hours, to control these weeds every year.
If left to grow they smother native bush, take over back yards and de-stabilise our native ecology. They can also harbour rats and some can be a health issue for us. Are these pest weeds taking over your backyard or neighbourhood? It’s time to flush ‘em out! Actually spring and autumn are best, but NOW is always better than NEVER.
Auckland Council’s Regional Pest Management Plan (RPMP) requires people in some areas to remove defined pest plants from their property. Urban Ark wants to take the lead and start freeing neighbourhoods of invasive pest plants right away. Talk to your neighbours about getting a team together to clear your street of our worst offenders (see below). Your local group may already be keen weeders, and if not you could start their weed removal wing. Check out our main weeding groups below.
