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. -

Desiccation response of seed of Clianthus spp., Carmichaelia muritai, Pittosporum crassifolium and Pittosporum eugenioides A thesis presented in partial fulfilment of the requirements for the degree of Master of AgriScience in Horticulture at Massey University, Palmerston North, New Zealand Kai Yu 2015 ABSTRACT New Zealand has a rich, diverse and unique of plant life. However, the conservation status of the New Zealand indigenous vascular flora is deteriorating, with 7.6% of this flora regarded as threatened with extinction. A series of conservation approaches are required to protect species against further loss. Developing ex-situ conservation of these species requires basic information such as seed storage behaviour and seed germination requirements to be determined. However, for many species this information is missing or incomplete. The objective of this study was to determine seed storage behaviour (response to desiccation), and/or seed coat characteristics in selected New Zealand native species. Five native tree and shrub species were studied: Carmichaelia muritai, Clianthus puniceus, Clianthus maximus, Pittosporum eugenioides, and Pittosporum crassifolium. Seeds of Clianthus maximus, Clianthus puniceus, and Carmichaelia muritai were found desiccation tolerant at low moisture content (down to ~2.5%), suggesting the storage behaviour is orthodox; storage trials need to be conducted to confirm this. In contrast, the storage behaviour of Pittosporum eugenioides and Pittosporum crassifolium appears to be non-orthodox since there was some loss of viability upon drying to low moisture contents. -

RESTORATION PLAN FOR THE SPENCER ROAD PART OF THE LAKE TARAWERA CATCHMENT R4152c RESTORATION PLAN FOR THE SPENCER ROAD PART OF THE LAKE TARAWERA CATCHMENT Contract Report No. 4152c February 2017 Updated February 2019 Project Team: Richard Gillies - Fieldwork, report author Jennifer Murray - Fieldwork, report author Sarah Beadel - Field assessment, project management, report author, peer review Prepared for: Lake Tarawera Ratepayers Association and Tarawera Landcare 2115 99 SALA STREET, WHAKAREWAREWA, 3010, P.O. BOX 7137, TE NGAE, ROTORUA 3042 Ph 07-343-9017; Fax 07-343-9018, email [email protected], www.wildlands.co.nz EXECUTIVE SUMMARY Tarawera Landcare 2115, via the Lake Tarawera Ratepayers Association, has signed a MoU with Rotorua Lakes Council regarding the management of Council land along the margins of Lake Tarawera between Otumutu Lagoon and Te Toroa Point. The site is c.6.5 km long and covers 24 ha. The Lake Tarawera Ratepayers Association has commissioned this plan to guide ecological management there. A separate plan has been developed for Māori land on Kariri Point. A review of background information and ecological surveys and assessments of the study area were undertaken during October-December 2016. Indigenous forest dominated by māhoe, mamaku, kāmahi, fivefinger and, in places, pōhutukawa and kānuka, occupies around 40% of the study area, and is representative of the vegetation regenerating after the 1886 Tarawera eruption. A distinctive feature is the presence of healthy numbers of the mistletoe Tupeia antarctica, an At Risk species, from Cliff Road Reserve northwards, attributable to ongoing possum control by the Tarawera community. Lakeshore vegetation provides roosting and nesting habitat for waterbirds, particularly dabchick, a Threatened endemic waterbird present along the entire shoreline. -
The Mistletoes a Literature Review
THE MISTLETOES A LITERATURE REVIEW Technical Bulletin No. 1242 June 1961 U.S. DEi>ARTMENT OF AGRICULTURE FOREST SERVICE THE MISTLETOES A LITERATURE REVIEW by Lake S. Gill and Frank G. Hawksworth Rocky Mountain Forest and Range Experiment Station Forest Service Growth Through Agricultural Progress Technical Bulletin No. 1242 June 1961 UNITED STATES DEPARTMENT OF AGRICULTURE WASHINGTON, D.C For sale by the Superintendent of Documents, U.S. Government Printing Office Washington 25, D.C. - Price 35 cents Preface striking advances have been made in recent years in the field of plant pathology, but most of these investigations have dealt with diseases caused by fungi, bacteria, or viruses. In contrast, progress toward an understanding of diseases caused by phanerogamic parasites has been relatively slow. Dodder (Cuscuta spp.) and broom rape {Orohanche spp.) are well-known parasites of agri- cultural crops and are serious pests in certain localities. The recent introduction of witchweed (Striga sp.) a potentially serious pest for corn-growing areas, into the United States (Gariss and Wells 1956) emphasizes the need for more knowledge of phanerogamic parasites. The mistletoes, because of their unusual growth habits, have been the object of curiosity for thousands of years. Not until the present century, however, has their role as damaging pests to forest, park, orchard, and ornamental trees become apparent. The mistletoes are most abundant in tropical areas, but they are also widely distributed in the temperate zone. The peak of destructive- ness of this family seems to be reached in western North America where several species of the highly parasitic dwarfmistletoes (Arceuthobium spp,) occur. -

DEVELOPMENT, TAXONOMIC SIGNIFICANCE and ECOLOGICAL ROLE of the CUTICULAR EPITHELIUM in the SANTALALES Carol A. Wilson & Clyd
IAWA Journal, Vol. 24 (2), 2003: 129–138 DEVELOPMENT, TAXONOMIC SIGNIFICANCE AND ECOLOGICAL ROLE OF THE CUTICULAR EPITHELIUM IN THE SANTALALES by Carol A. Wilson & Clyde L. Calvin Department of Biology, Portland State University, Portland OR 97207, U.S.A. SUMMARY All genera in the mistletoe family Viscaceae develop a secondary protec- tive covering, the cuticular epithelium, that replaces the epidermis. The cuticular epithelium also occurs in the Eremolepidaceae and some genera within the related family Santalaceae. This secondary covering, unlike the periderm, lacks lenticels or their functional equivalent. We suggest that the cuticular epithelium provides a greater degree of control over tran- spirational water loss in older plant parts. The cuticular epithelium may arise in the epidermis, subepidermal layer, or in deeper tissues of the stem. Bark strands of the endophytic system, where they are in contact with either nonliving host tissues or the external environment, also form a cu- ticular epithelium. The epidermal feature, stomatal orientation, was also studied. All genera in the Viscaceae and Eremolepidaceae have stomata with a transverse orientation. The presence or absence of a cuticular epi- thelium and stomatal orientation are vegetative characters with potential taxonomic value. Key words: Cuticular epithelium, parasitic angiosperm, periderm, San- talales, stomatal orientation, transpiration, Viscaceae. INTRODUCTION In the vast majority of plants having secondary growth, the epidermis is replaced by a covering of secondary origin, the periderm. The first periderm may arise in the epi- dermis, the subepidermal layer, or in deeper tissues of the stem (Esau 1977). The roots of woody plants also form a periderm, although its origin is typically from pericyclic derivatives rather than from cortex or epidermis.
