New Zealand Tea Tree Leptospermum scoparium; Myrtaceae Planting Zone : 14-24 (Sunset) Size of plant : height 6-15 feet; spread 3-6 feet Bloom description and season : ½-1” single or double showy flowers in red, pink or white petals surround a hard center cone that matures into a woody capsule that remains on tree long after petals drop. Profuse blooms in spring, some visible into summer. Exposure : Full sun Pruning needs : Minimal. Thin growth to shape while young; avoid pruning bare wood as new growth is unlikely. Older, bare-based or overgrown shrubs can be trimmed into small trees. Water needs : Minimal once established, depending on soil, sun, wind conditions and winter rainfall. Water to a depth of two inches in summer for the first two years. Description : Long-lived evergreen ornamental shrub originally from Australia and New Zealand, used by natives as a source of Vitamin C (brewed tea, beer), medicine, essential oils and honey. Thrives in coastal conditions; tolerates poor soil but well-drained soil that is slightly acidic. Feed annually with 12-12-12 fertilizer (half-strength to prevent root burn) in early spring before new growth appears; water in thoroughly. Add mulch to suppress weeds and decrease water evaporation. The Tea Tree works well in containers, coastal and rock gardens, and as a border, while considering the space needed for a full-grown tree. Bees, butterflies and birds are attracted to the slightly fragrant foliage, and it is deer resistant. Overall, the plant is pest- resistant, but may be susceptible to scale and thrips.

Kirkpatrick (with two tables, four text-figures and one appendix) KIRKPATRICK, J.B., 1999 (31:x): The characteristics and management problems of the vegetation and flora of the Huntingfield area, southern Tasmania. Pap. Proc. R. Soc. Tasm. 133(1): 103-113. ISSN 0080-4703. School of Geography and Environmental Studies, University ofTasmania, GPO Box 252-78, Hobart, Tasmania, Australia 7001. The Huntingfield area has a varied vegetation, including substantial areas ofEucalyptus amygdalina heathy woodland, heath, buttongrass moorland and E. amygdalina shrubbyforest, with smaller areas ofwetland, grassland and E. ovata shrubbyforest. Six floristic communities are described for the area. Two hundred and one native vascular plant taxa, 26 moss species and ten liverworts are known from the area, which is particularly rich in orchids, two ofwhich are rare in Tasmania. Four other plant species are known to be rare and/or unreserved inTasmania. Sixty-four exotic plantspecies have been observed in the area, most ofwhich do not threaten the native biodiversity. However, a group offire-adapted shrubs are potentially serious invaders. Management problems in the area include the maintenance ofopen areas, weed invasion, pathogen invasion, introduced animals, fire, mechanised recreation, drainage from houses and roads, rubbish dumping and the gathering offirewood, sand and plants. Key Words: flora, forest, heath, Huntingfield, management, Tasmania, vegetation, wetland, woodland. INTRODUCTION species with the most cover in the shrub stratum (dominant species) was noted.

Is Kanuka and Manuka Establishment in Grassland Constrained by Mycorrhizal Abundance?
172 AvailableNew on-lineZealand at: Journal http://www.newzealandecology.org/nzje/ of Ecology, Vol. 37, No. 2, 2013 Is kanuka and manuka establishment in grassland constrained by mycorrhizal abundance?

The aim of this study was to determine if establishment of kanuka and manuka from seed in grassland distant from stands of these species might be constrained by lack of appropriate mycorrhizal fungi. Both species were grown in an unsterilised grassland soil from a low- productivity montane site assumed to be devoid of appropriate mycorrhizal fungi and inoculated with sterilised or unsterilised O-horizon or mineral soil from beneath three kanuka and three manuka communities expected to contain such fungi. Inoculation with unsterilised O-horizon soil improved kanuka biomass by 36–92%, depending on the source of the inoculant. Inoculation did not improve manuka biomass. No ectomycorrhizal infection was observed on either kanuka or manuka in samples examined under binocular microscope. The biomass response by kanuka to inoculation may be due to introduction of more effective arbuscular mycorrhizal fungi from kanuka communities or possibly to the introduction of soil microorganisms.

The Application of Stem Analysis Methods to Estimate Carbon Sequestration in Arboreal Shrubs from a Single Measurement of Field Plots
Forests 2014, 5, 919-935; doi:10.3390/f5050919 OPEN ACCESS forests ISSN 1999-4907 www.mdpi.com/journal/forests Article The Application of Stem Analysis Methods to Estimate Carbon Sequestration in Arboreal Shrubs from a Single Measurement of Field Plots Peter N. Beets *, Mark O. Kimberley, Graeme R. Oliver and Stephen H. Pearce New Zealand Forest Research Institute Ltd., 49 Sala Street, Rotorua 3010, New Zealand; E-Mails: [email protected] (M.O.K.); [email protected] (G.R.O.); [email protected] (S.H.P.) * Author to whom correspondence should be addressed; E-Mail: [email protected]; Tel.: +64-7-343-5899; Fax: +64-7-348-0952. Received: 14 January 2014; in revised form: 2 May 2014 / Accepted: 5 May 2014 / Published: 16 May 2014 Abstract: Repeated measurements of plots are usually made to directly determine carbon stock changes over time. However, it is sometimes only practical or feasible to inventory plots at the end of a period of interest, and stock changes need to be predicted retrospectively from supplementary information on growth rate. This situation applied to the natural stratum of post-1989 forest in New Zealand, for which carbon sequestration over Commitment Period 1 (2008–2012) of the Kyoto Protocol needed to be estimated from inventory data acquired in 2012. A pilot study was undertaken to test and refine methods that could be applied in the national inventory, utilizing plots that had been installed in eligible post-1989 natural forest in 2008. The plots had actual measurements and shrub biomass sampling to directly estimate carbon stocks in 2008.

Leptospermum — A New Image 55 Leptospermum — A New Image© John Seelye, Bev Hofmann, Garry Burge, and Ed Morgan New Zealand Institute for Crop & Food Research Ltd, Private Bag 11600, Palmerston North Ross Bicknell New Zealand Institute for Crop & Food Research Ltd, Private Bag 4704, Christchurch INTRODUCTION The genus Leptospermum contains more than 70 species that are endemic to Southeast Asia, Australia, and New Zealand. The majority of species are endemic to Australia (Thompson, 1983; 1989). New Zealand has only one species, L. scoparium, which is also endemic to New South Wales, Victoria, and Tasmania. Selected forms of several species are sold in the nursery trade. However, only L. scoparium has been extensively bred as a garden plant (Dawson, 1990). More than 100 cultivars of L. scoparium have been named, but less than 30 cultivars have been bred from all the other species (Harris et al., 1995). Flower colour of L. scoparium ranges from white to pink, to crimson, with both single- and double-flowered types, and plant forms from upright to prostrate. The genetic base of these L. scoparium cultivars is quite narrow. The red petal colour of most cultivars appears to have been derived from 2 or 3 wild accessions (Harrison, 1974). Most of the original breeding of L. scoparium was conducted by Lammerts (1945) in California. He crossed a red-petaled cultivar, L. scoparium ‘Nichollsii’, with a pale-pink double-flowered cultivar, L. scoparium ‘Rose Double’, and subsequent populations of this breeding were generated by selfing or intercross- ing their progeny. This possibly explains why there is little variation in many characteristics, such as cold tolerance, in the main cultivars despite this variation in wild ecotypes (Harris and Decourtye, 1991).
