Bio–controls for NZ farming
Farming pests that costs millions of dollars in control and lost production every year are about to find life a lot tougher.
Several new bio–controls have been released at sites throughout New Zealand by scientist Hugh Gourlay to try and control invasive weds including Scotch broom and Californian thistle. He says the releases are not a “quick fix”, instead their introduction will need to coincide with ongoing and wider on–farm management practices.
Furthermore, a bio–control introduced a decade ago to help control a pest plant in the Central North Island appears to have finally taken hold.

Embracing nature in a redeveloped Christchurch
Our 'Transitions' exhibition garden at the Ellerslie Show showcases some possibilities - including pocket parks, living walls, green roofs and natural water treatment. It shows how we can intergrate people, nature and functionality, and restore some of the plants and wildlife that have been lost. Follow Landcare Research

Christchurch's residents have expressed a strong desire for a greener central city. 
Science in Focus - Biosystematics
The Biosystematics Team brings together over 40 science staff researching New Zealand's most diverse groups of life on land and in freshwater. Research addresses our native and introduced plants, insects and other arthropods, fungi, and plant–associated bacteria, to describe New Zealand's biodiversity and species interrelationships and to make that information readily accessible. Currently, less than 50% of New Zealand's estimated total biodiversity in these groups has been recorded. Research is supported by Landcare Research's five national and international collections of these organisms, along with specialised databases and libraries. The biological collections also hold voucher specimens that authenticate biological studies in diverse branches of science. Biosystematists link with colleagues in ecology, conservation, genetics, weed and pest control, plant pathology, bioprospecting, and biosecurity to provide authoritative names and specimen–linked information integral to the applied sciences. Increasingly, species identification and determination of species relationships involves DNA analyses in addition to morphological and biochemical approaches. Holdings of the national collections are a key source of DNA for these studies.
