Temporal Development and Regeneration Dynamics of Restored Urban Forests
Temporal Development and Regeneration Dynamics of Restored Urban Forests By Katherine de Silva A thesis submitted to the Victoria University of Wellington in fulfilment of the requirements for the degree of Masters in Ecology & Biodiversity School of Biological Sciences Faculty of Sciences Victoria University of Wellington October 2019 Supervisors: Stephen Hartley. Director of the Centre of Biodiversity & Restoration Ecology, Victoria University of Wellington Kiri Joy Wallace. Postdoctoral Fellow, Environmental Research Institute, University of Waikato. Katherine de Silva: Temporal Development and Regeneration Dynamics of Restored Urban Forests, © October 2019. 2 ABSTRACT Urban forest restoration programmes are a key tool used to initiate, re-create or accelerate the succession of forest species; improving ecosystem services, function, resilience and biodiversity. Succession is a temporal shift in species dominance driven by abiotic and biotic influences, but over decadal timescales the trajectory and success of restoration plantings in degraded urban environments can be hindered. To facilitate the successful reconstruction of forest ecosystems from scratch, an understanding of the temporal patterns in planted forest development, dynamics of seedling regeneration and dominant drivers of seedling diversity is required. Using a chronosequence approach, permanent plots were established at 44 restored urban forests aged 5 to 59 years since initial plantings took place, across five New Zealand cities between Wellington and Invercargill. Vegetation surveys were undertaken and data on micro- climate were collected. This study examined the 1) temporal dynamics of restored urban forest development and seedling regeneration and 2) dominant drivers of seedling regeneration. Data were analysed using linear regression models, breakpoint analysis and mixed-effects modelling. Early forest development (<20 years) exhibited the most changes in canopy composition and structure, forest floor dynamics, seedling community and microclimate. -
Growing Plants in the Wakatipu
The Wakatipu Basin has some of the most unique and adaptive groups of plants found anywhere on the planet. Extensive modification of our landscape has seen these plants all but disappear from large parts of the basin. However, the importance of native species in New Zealand is being gradually recognised, and the importance of plants in the Wakatipu Basin is no exception. Many in the past have considered native plants slow growing and poorly adaptive, but the truth is the complete opposite. Native species found in the basin have had millions of years to adapt to its harsh, but beautiful terrain. It is important for anyone considering planting to determine what plants are right for this area so they can not only thrive, but help increase biodiversity values and bring back the native birds. This practical guide has been written to help anyone who is interested in planting native species within the Wakatipu Basin. It tells the story of the region, and explains how to best enhance one’s garden or patch of land. It includes helpful tips that will improve the success of any native plantings, particularly when considering sites encompassing the challenging micro-climates found throughout the district. It provides helpful advice to the first time gardener or the seasoned pro. It covers all aspects of planting, including maintenance advice and plant lists, so that even the most amateur gardener can soon have a thriving native patch filled with native bird song.

Novel Habitats, Rare Plants and Roots Traits A thesis submitted in partial fulfilment of the requirements for the Degree of Master of Applied Science at Lincoln University by Paula Ann Greer Lincoln University 2017 Abstract of a thesis submitted in partial fulfilment of the requirements for the Degree of Master of Applied Science. Abstract Novel habitats, rare plants and root traits. by Paula Ann Greer The loss of native plant species through habitat loss has been happening in NZ since the arrival of humans. This is especially true in Canterbury where less than 1% of the lowland plains are believed to be covered in remnant native vegetation. Rural land uses are changing and farm intensification is creating novel habitats, including farm irrigation earth dams. Dam engineers prefer not to have plants growing on dams. Earth dams are consented for 100 years, they could be used to support threatened native plants. Within the farm conversion of the present study dams have created an average of 1.7 hectares of ‘new land’ on their outside slope alone, which is the area of my research. -

Patterns of flammability across the vascular plant phylogeny, with special emphasis on the genus Dracophyllum A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of philosophy at Lincoln University by Xinglei Cui Lincoln University 2020 Abstract of a thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of philosophy. Abstract Patterns of flammability across the vascular plant phylogeny, with special emphasis on the genus Dracophyllum by Xinglei Cui Fire has been part of the environment for the entire history of terrestrial plants and is a common disturbance agent in many ecosystems across the world. Fire has a significant role in influencing the structure, pattern and function of many ecosystems. Plant flammability, which is the ability of a plant to burn and sustain a flame, is an important driver of fire in terrestrial ecosystems and thus has a fundamental role in ecosystem dynamics and species evolution. However, the factors that have influenced the evolution of flammability remain unclear. -

LIZARD GARDENS ‒ a Planting Guide
LIZARD GARDENS – A Planting Guide New Zealand’s skinks and geckos have experienced chronic decline in the face of introduced pests, namely rats, pet cats, mice, hedgehogs and mustelids (stoats, ferrets and weasels). These days most peoples’ experience of lizards is via the one their cat brought in. This will continue to be the norm, unless we do something about it! The three main things you can do to help skinks and geckos in your backyard are to provide food, shelter and undertake pest control. Food: berries and nectar from fruiting and flowering native plants, insects and moisture i.e. lots of mulch. Shelter: rock piles, rotting logs, driftwood, stacks of timber, retaining walls, don’t throw out your prunings, dump them in a pile out of the way, skinks will thank you for it. Pest control: get trapping! Trapping rats and mice is a start but hedgehogs are actually a real problem for lizards in urban settings. Consider getting a DOC200 to trap those spiny pests. You can bury them under your native plants to provide an excellent source of fertiliser. Bait is effective for rodents in particular, and means you don’t have to deal with dead bodies. Also, keep your cat inside at night and consider not replacing it when it dies. To help you get started, this planting guide has been developed by gardeners and conservationists from the Kāpiti Coast. We live in a harsh coastal sand environment battered by salt spray, high wind and regular droughts. The following plant list has been developed with that in mind. -

Breeding systems and reproduction of indigenous shrubs in fragmented ecosystems A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy III Plant Ecology at Massey University by Merilyn F Merrett .. � ... : -- �. � Massey University Palrnerston North, New Zealand 2006 Abstract Sixteen native shrub species with various breeding systems and pollination syndromes were investigated in geographically separated populations to determine breeding systems, reproductive success, population structure, and habitat characteristics. Of the sixteen species, seven are hermaphroditic, seven dioecious, and two gynodioecious. Two of the dioecious species are cryptically dioecious, producing what appear to be perfect, hermaphroditic flowers,but that functionas either male or female. One of the study species, Raukauaanomalus, was thought to be dioecious, but proved to be hermaphroditic. Teucridium parvifolium, was thought to be hermaphroditic, but some populations are gynodioecious. There was variation in self-compatibility among the fo ur AIseuosmia species; two are self-compatible and two are self-incompatible. Self incompatibility was consistent amongst individuals only in A. quercifolia at both study sites, whereas individuals in A. macrophylia ranged from highly self-incompatible to self-compatible amongst fo ur study sites. The remainder of the hermaphroditic study species are self-compatible. Five of the species appear to have dual pollination syndromes, e.g., bird-moth, wind-insect, wind-animal. High levels of pollen limitation were identified in three species at fo ur of the 34 study sites. -

Accepted: July 10, 2019 Data deposition: This project has been deposited at EMBL/GenBank/DDBJ under the accession PRJEB19438 - PRJEB19449. Abstract Frankia strains induce the formation of nitrogen-fixing nodules on roots of actinorhizal plants. Phylogenetically, Frankia strains can be grouped in four clusters. The earliest divergent cluster, cluster-2, has a particularly wide host range. The analysis of cluster-2 strains has been hampered by the fact that with two exceptions, they could never be cultured. In this study, 12 Frankia-enriched meta- genomes of Frankia cluster-2 strains or strain assemblages were sequenced based on seven inoculum sources. Sequences obtained via DNA isolated from whole nodules were compared with those of DNA isolated from fractionated preparations enhanced in the Frankia symbiotic structures. -

Friends of the Christchurch Botanic Gardens Newsletter 76
Newsletter For Friends of the Christchurch Botanic Gardens Inc To Promote, Protect, & Preserve No 76, Autumn 2009 President’s Report Preparations for the Ellerslie International Flower Show are already underway in Hagley Park. Many of us who are interested in horticulture and gardening are looking forward to this major event to be opened to the public during the second week of March. There will no doubt be a certain amount of glitz and glamour associated with such an event. However, looking beyond Ellerslie 2009, I really hope that this event will reinforce the greater need to maintain and enhance the city’s public garden areas so as to keep Christchurch as the country’s leading garden city. In regards to our own Botanic Gardens I am also hopeful that the Ellerslie Flower Show will have some spin-off benefits. What a wonderful opportunity we have to show off our gardens to the visitors going to the Ellerslie Show and within such a short walking distance from it. The architectural competition for the design of the new Botanic Gardens Centre is currently being considered by the Council and a decision should be made soon. This will be great asset for the gardens and is long overdue. Without doubt, a facility of this standard will help raise the gardens international rating. It goes without saying of course, that the staff especially will appreciate the new building as well as the Friends plus the numerous visitors who come to the gardens throughout the whole year. Please make sure you visit the Friends exhibit at the Ellerslie Show.
