Since then, a third edition (Stace, 2010) has been issued containing numerous taxonomic and nomenclatural changes as well as additions and exclusions to taxa listed in the second edition. Consequently, although the objective of this revised guide hast altered and much of the original text has been retained with only minor amendments, many new taxa have been included and there have been substantial alterations to the references listed. We are grateful to A.O. Chater and C.D. Preston for their comments on an earlier draft of these notes, and to the Biological Records Centre at the Centre for Ecology and Hydrology for organising and funding the printing of this booklet.

  • 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.

Common, are increasingly regarded sites for potential development. The Common has been the subject of debate during the last three years. The area has been identified as an urban open space containing highly valued natural and historical_-cultural assets. Significant areas such as this need to be protected from development and managed accordingly. They can be utilised as areas for environmental education, semi-formal recreation or aesthetic enjoyment. The Common typifies management problems that may be experienced in the compromise of using an area of predominantly natural vegetation for an unrestricted semi-formal recreation area. This report summarizes the importance of the Common and identifies the concerns surrounding its present management.

The first feast for bees, in the shrubland short of trees not breeze. Sun’s rays soon last longer in the days: Babianas, Chlorophytums, Geissorhizas, Gladiolius’s, Hesperanthas, Lachenalias, Moraeas and Trachyandras spread their cheerful gaze. Accompanied by annual daisies and bright gladioli filling the air with strong scents of honey - monkey beetles waste no time as they perch upon delicate flowers, lest they are caught in the season’s showers. As if to suggest this is the best nature sends small midge flies to pollinate in jest, and surround mammals to tease their bloody channels. Another month has come and gone - not long now for the raaptol and Micranthus which provide nectar for brown butterflies and painted ladies. Then is the last sequence of bulbs - the fine white-filled fields of chinkerinchees. Grasses’ hour is now soaking up the sun displaying beautifully crafted silhouettes till summers end. As if heaven sent delicate geophytes are still producing their charm, when botanists avoid the midday sun. A brief lapse in displays until the autumn reds begin the seasonal cycles.” Figure a: From left to right: Moraea villosa (Ker Gawl.) Ker Gawl.
