Rangitoto is a shallow marine basaltic shield volcano, with gently sloping fragmented lava flanks topped by a central scoria cone. Invasive weed control aims to protect the native plant communities and the unique plant successional processes from bare lava to forest. There are 72 species of invasive weeds destined for control or eradication, many of which are not managed as weeds elsewhere in New Zealand. A draft plan was devised in 1995 that considered distribution, impact on the native vegetation, and efficiency of propagule dispersal in setting priorities for control. The result was a strategy with a top priority of controlling around 20 species that had the potential to drastically alter the natural vegetation, but still had very limited populations. The second stage of the strategy was to control the remaining 50 species on a geographical basis, proceeding from the least-infested areas to the most densely infested, generally dictated by the distribution of the widely-distributed alien invasive Rhamnus alaternus (Rhamnaceae). The weed management plan has evolved over five years with improving control techniques, new herbicides, new weed finds, and better mapping and relocation systems.

Vegetation change after artificial disturbance in an alpine Chionochloa pallens grassland in New Zeland / Kelvin M. Llyod (2003) 

Public Citation est un tiré à part de 27 (1) - 2003 (New Zealand journal of ecology) Titre : Vegetation change after artificial disturbance in an alpine Chionochloa pallens grassland in New Zeland Type de document : Tiré à part de revue Auteurs : Kelvin M.

Twelve years after their creation, the 50 cm _ 50 cm gaps supported a distinctive vegetation composed of a mixture of perennial forbs, grasses and mosses. Three species (Bryum sp., Epilobium alsinoides and Plantago novae-zelandiae) were recorded only in the gaps. Plantago novae-zelandiae and Polytrichum juniperinum had their highest frequency in the centres of the gaps, while Celmisia gracilenta and Geranium microphyllum were most frequent at the edges. The distinctive species composition of the gap plots indicates that they are still in an early stage of succession, assuming an eventual reversion to the surrounding climax grassland Permalink : https://biblio.cbnpmp.fr/index.php?lvl=notice_display&id=133800 Llyod, Kelvin M., Lee, William George (1950-), Fenner, Michael (1949-), Loughnan, Abi E. 2003 Vegetation change after artificial disturbance in an alpine Chionochloa pallens grassland in New Zeland.
