Phytoremediation of microbial contamination in soil by New Zealand native plants

About 110 introduced aphid species (Hemiptera Aphididae) have been recorded in New Zealand Only 12 indigenous species have been recorded On average there has been about one new aphid incursion into New Zealand per year over the last 130 years although this rate has declined dramatically in recent years The origins of introduced aphids appear to include most parts of the globe Many introduced aphids damage economically important plants through their feeding and transmitting plant viruses Less quantifiable environmental impacts include injury to native plants and the displacement of native aphids on their host plants Aspects of aphid biology such as small size parthenogenetic reproduction high reproductive rates short generation time rapid dispersal and eruptive population dynamics pose particularly difficult challenges for aphid biosecurity in New Zealand

Successional Vegetation

Despite the concern of some nineteenth- and early twentieth-century biologists, relatively few alien species have become established in undisturbed forests of Australia, Madagascar or New Zealand. All three countries have large 'naturalized' floras adapted to frequent disturbance. The short-term advantages of these alien plants - short life cycles, fast growth, abundant seed and plasticity of habit - have allowed them to cover large areas of disturbed ground and to coexist with native plants in early successional vegetation. Very few persist in mature forest. The threat to the austral forests is human disturbance, and there is need for research on the native plants which perform the specialized role of repairing canopy after disturbance.

Tradescantia Fluminensis

Tradescantia fluminensis Plectranthus ciliatus Asparagus scandens Hedera helix Lamium galeobdolon and Selaginella kraussiana are all matforming invasive species that limit regeneration of native plants in forest remnants in New Zealand Experiments using potted specimens of these weeds showed that low rates (338675 g/ha) of the herbicide triclopyr gave >90 defoliation of T fluminensis A scandens and L galeobdolon but a higher rate of 1350 g/ha only gave 85 defoliation of H helix Diquat gave 85 defoliation of P ciliatus Aminopyralid was effective against S kraussiana but was very slow acting These experiments have identified herbicides and application rates for effective forest weed management to facilitate native plant regeneration in New Zealand temperate forests

Future Work

Context Invasive mammals have been removed from at least 100 offshore islands around New Zealand, covering a total area of around 45 000 ha. Aims To review the outcomes of eradications, the statutory and social environment in which the eradications were conducted, and the lessons provided for future work. Methods Native species to benefit from the eradications were identified, as were the reasons for the eradications and the agencies responsible. Examples are provided using case studies. Key results Three loosely linked work streams were revealed: research into efficient baits and baiting methods, threatened species-led projects nested within priorities for species recovery and supported by legislation, and community-led projects instigated by restoration societies. At least 180 populations of 14 species of invasive mammals were removed. Numerous species of native plants, invertebrates and more than 70 species of terrestrial vertebrates are recovering or are likely to recover as a result of the eradications. Partnerships have been formed with Māori and innovative projects developed with community groups. Conclusions Eradications of invasive mammals are aggressive conservation actions that can have wide benefits for biodiversity but can also be controversial, technically demanding and expensive. Implications Eradications are multi-scale problems. If they are to gain public acceptance, evidence is needed in support. This evidence can include understanding the detrimental effects of invasive species, the likely responses of native biodiversity, and the benefits ensuing from their recovery. However, the way this evidence is gained and communicated will also require deep understanding of nuances in regional political and cultural environments.
