We argue that all three species are indigenous and arrived on their respective islands within the last 200years by natural processes, most likely from warmer neighbouring islands, where these species have more extensive distributions. communities. Three tree species, Cabbage Tree, Kahikatea and Manuka, emerged in the field but did not survive beyond 6 months. Since germination requirements of M. parvifolia have not yet been described, an understanding of the effects of low and high temperatures on seed germination of this native tree is vital to developing successful coastal plain restoration strategies. There was rapid germination of Sophora prostrata seeds with 100% of the seed germinating in the light and dark. Air‐dried seed also germinated we11 (>80%) Once transferred to a moist incubation environment. H. glabrata is an early seral tree on recently disturbed sites. Restoration of Hebe cupressoides populations in the wild will require control of this introduced grass sward. Resistance is an attribute that this genus demonstrates admirably; whether standing up in the face of biting, salt-laden winds on our coastlines, or weaving their way through the exposed surface of braided riverbeds. At the time of our visit to Cape Campbell, two different species of copper butterfly (Lycaena salustius and L. feredayi, as far as I can tell) appeared to be sharing the habitat, as our native ‘Coppers’ often do. The response of both species to treatments which break physical dormancy may indicate an ecological role for high heat events such as fire. The present paper examines the germination requirements of the seeds of two woody species (Koelreuteria paniculata and Mahonia aquifolium). Germination is more rapid at temperatures of 12-25°C, in darkness or low light intensity, and high water potential, but many seeds eventually germinate at temperatures from 5-30°C, under high light (295 μmol m-2sec-1) or very low water potential (1.5 mPa). 2002). The ability of an insect to choose a plant for food and/or oviposition site is referred to as ''preference'' (Singer 1986). Seeds that were incubated immediately after extraction from mature fruits germinated readi1y (87%), and leaching did not further enhance germination. Dans le cadre de la dynamique mondiale de conservation, de protection et de restauration de la biodiversité, il convient de caractériser au mieux la flore néo-calédonienne foisonnante de plantes uniques. Although low viability may be responsible for this, there is increasing recent evidence that low germination in a range of native species may be because of seed dormancy (Hampton & Hill 2002; ... Hampton & Hill (2002) reported the dry weight of a P. tenax seed as 0.005 g. Phormium tenax has an orthodox seed that tolerates drying, remaining viable when desiccated to a moisture content of <20%. The genus Carex, with its wide distribution and large number of species yet with a rather uniform life history, is a very convenient group for comparative studies of germination ecology at the generic level. Effects of red light (R) and far-red light (FR), and selected photon flux The effects were studied of scarification (concentrated sulphuric acid for UP to 5 min), hching (for up to 2 h), stratification, and storage environment on germination of seed of the New Zealand endemic tree Melicytus ramflorus. than that of R required to induce initial germination. 8.2 - Ground Cover Plants for Restoration of Backdunes POHUEHUE Wire vine (Muehlenbeckia complexa) Description: A wiry creeping vine forming dense springy mats up to 1m high; climbs over other vegetation and any obstacles such as fencing. Thus, it can be concluded that the Carex species tested have broadly similar germination response patterns.
