Johnson Grass
"Johnson Grass – Check your backyard Johnson Grass (Sorghum halepense) is an extremely invasive grass. It has been a big problem in New Zealand before. New Zealand was Johnson Grass-free for 14 years. But in 2021 Johnson Grass was found in a South Auckland backyard. It looks like a strong grass or maize plant. If you find it, please take photos and report it. It has a distinctive whitish midrib on the underside of the leaf. It flowers from January to March. #CheckYourBackyard

"Red-eared sliders are sold as pets. These turtles grow to about 30cm and live for as long as 50 years. Many escape or are released to our waterways − and that’s not good. This species is very invasive: they can produce around 400 offspring, have a broad diet and are hard to catch. There’s concern they will harm native aquatic plants, isects, eels, small fish species, and ground-nesting birds. Auckland Council is banning sale of these turtles by pet stores. Please beware of taking on such a long-lived creature as a pet. Don’t dump unwanted pets like red-eared sliders into the environment. Instead, contact your local pet shop, SPCA or animal rescue organisation.

"The Central plateau is well looked after by a supreme good sort in Dave Cade. Working to protect our freshwater and the wonderful wild places special to NZ Dave heads up the Horizons Check Clean Dry programme. A fisher, outdoors person as well as an ex dairy farmer and employee of DOC, Dave has unique perspective on messaging and interacting with the public; it is is innovative and constantly evolving. Evolving, as unfortunately he is constantly disappointed many people don’t take steps to look after the wonderful places we have and treat them selfishly, rather than leaving them in a better state for the next generation. From a poem about the blue duck to talkback radio calls, and alter egos Dame Didymo Davina and Victor the Viking; Daves use of all media platforms and memorable personalities to get cut-through knows no bounds.

Pete Profile
"Pete is a professional gardener but when he's not hard at work tidying other people's gardens he tends to be pulling weeds from our parks and reserves in the Coromandel. He is always prepared to go the extra mile and believes in making a change for good for all New Zealanders.
