Shrubland and shrubland association (including coastal shrubland) The shrubland category is very broad, and includes diverse vegetation associations that could not be described as forest, wetland or duneland / sandfield. Shrubland areas comprise only 8.7% of the natural areas surveyed in this Ecological District. Manuka and kanuka are the most common shrubland types in the District. In the site reports coastal shrubland if defined as occuring adjacent to or within 1 km of the coast. Twelve shrubland or shrubland associations were identified. The largest area of shrubland is found on the coastal side of the Waipoua Forest (O06/001). Six shrubland types were identified within the large forest tract of O06/001: • Baumea spp.-umbrella fern • Dracophyllum lessonianum-umbrella fern-manuka • Kanuka/manuka • Manuka • Pate-wineberry • Towai Outside the large forest tract, pockets of shrubland/associations occur at O06/030, O07/001 (shrubland type unknown), O07/005, P06/041, and P07/042 and are represented by: • Kanuka/manuka (O06/030), (O07/001), (P07/002) • Kanuka/manuka-towai (P06/042) • Kotukutuku-wheki-wineberry (P06/041) • Manuka (O07/001, O07/005) • Mapou (O07/005) Associations on dunes occur within two sites in the District, Te Kaiatewhetu Shrublands and Arai te Uru Coastal Strip (O06/015) and Waipoua Coastal Strip and Taha Moana Scenic Reserve (O06/027). • Oioi-harakeke-hangehange-knobby association occurs at O06/015 clubrush-manuka-toetoe coastal A diversity of associations occurs at O06/027 including: • Baumea sp. • Manuka-Gleichenia sp. • Harakeke-manuka-toetoe • Toetoe-knobby clubrush • Oioi • Shore bindweed-Spinifex • Carex sp. On the steep coastal bluffs of Maunganui Bluff (O07/009) the vegetation is characterised by strap-shaped leaved plants tolerant of coastal winds and thin soils (Esler and Dobbins 1977). • kowharawhara-Astelia solandri 20 Natural areas of Tutamoe Ecological District
• Astelia solandri-Chionochloa bromoides-harakeke There are two exotic scrubland types recorded on the coast, gorse (O07/008) and Chinese privet (O06/021). Fernland Fernland vegetation types are recorded from two sites. • bracken (O06/001) • wheki (O06/030) Forest Approximately 90.4% of the natural areas of the Tutamoe Ecological District are represented by forest. The large areas of indigenous old growth forest are an outstanding feature of this District. A diversity of forest types were recorded. Undoubtedly there are many other forest types that have not been identified within the limits of this survey. Coastal forest Many habitats in this Ecological District contain canopy species typical of coastal forest such as kohekohe, karaka, pohutukawa, and puriri. However, in this report, only forest directly adjacent to the coast or within 1 km of the coast, are described as coastal forest in the site reports. Forest alongside the coast is represented at O06/001, O06/015, O06/027, and O07/009. Maunganui Bluff Scenic Reserve (O07/009), which was logged around the turn of the century (Esler and Dobbins 1977), contains the most diverse coastal habitat recorded in this survey. Coastal forest types in this District include: • karaka (O06/015) • kohekohe-mapou-Olearia albida-pohutukawa (O07/009) • kohekohe-pohutukawa-puriri-taraire (O07/009) • mamangi (O06/001) • pohutukawa (O06/015), (O06/027), (O07/009) • taraire (O07/009) • taraire-nikau (O07/009) • pohutukawa-towai (O07/001) Broadleaf forest The main broadleaf forest types are: Taraire forest Taraire forest is the most widespread forest type recorded in this survey. Taraire forest has been recorded at 15 sites and two small sites O06/022 and O07/011 are solely defined by taraire. The majority of taraire forest occurs on Waipoua basalt. Fourteen sites contain abundant taraire. Species occurring frequently include northern rata, puriri, karaka, kohekohe, rewarewa, nikau, kahikatea, towai, hinau, tawa, and totara. A diversity of species are occasional, including, kauri, pukatea, miro, matai, mangeao, rimu, houhere and mamaku. PNAP reconnasance survey report 21
