NZ Transport Agency and Tauranga City Council Mangatawa Drain Flood Bypass and TEM Stormwater AEE The mown grass areas were generally dominated by tall fescue. On the seaward side of the cabbage tree scrub there was a large damp open area of this grass that contained a few cabbage trees and large clumps of pampas grass. The limited diversity of this scrub vegetation, and also the near absence of weeds such as Chinese privet and honeysuckle, indicate that (except for some of the larger cabbage trees) the vegetation that surrounds the pond is mostly a planted one. [The only historical information located was the topographical sheet NZMS 1 “Tauranga”, 3rd edn, 1965. This (Figure 2.1) shows the site (and beyond) as a rectangular block of scrub. Possibly however there was some subsequent clearance of all but the cabbage trees, before the pond was formed]. b) Avifauna The avifauna was assessed in a walkover of these areas and at various locations their avifaunal characteristics noted. Recorded calls were played of spotless crake, fernbird and banded rail using a Johnny Stewart MS512 Wildlife Caller with an S2500 15 watt speaker and amplifier. Calls for spotless crake were played at several points beside the aquatic habitat of the Stormwater Treatment Wetland and the SES while; fernbird and banded rail calls were played within the rushmarsh and mangrove habitat of the SES. Species of birds observed utilising the site and their principal habitats are shown in Table 6. A total of 15 species was recorded with the higher diversity applying to the stormwater treatment area as a result of its abundant and flowering flax together with cabbage trees and native shrubs. Of the fifteen species, six were native, one endemic and eight introduced. One species that is considered to be of conservation concern was recorded. North Island fernbird was present in the SES – it is rated as “sparse” (at risk) on a national basis. A total of 13 species was recorded in these areas, a diversity that may have been enhanced as a result of abundant flax flowers that were being utilised as a food source by several species. All the birds recorded in this area were common or abundant species as follows: Status: Final Page 53 April 2009 Project Number: 3932036 NZ1-1552092-Mangatawa Drain Flood Bypass and TEM Stormwater AEE
NZ Transport Agency and Tauranga City Council Mangatawa Drain Flood Bypass and TEM Stormwater AEE Table 6: Species of Birds Observed utilising the wetland and their Principal Habitats c) Herpetofauna The availability of native reptile habitat was visually assessed within the stormwater treatment wetland on 28 November 2008. The available habitat within the wetland was relatively open, with flax (Phormium tenax), Coprosma spp., pampas and rank grassland patchily abundant. These characteristics provide ideal habitat for terrestrial skinks, and some gecko species. Thirty sampling stations were laid throughout Te Maunga wetland on 26 November 2008, in areas most likely to provide lizard habitat (e.g. bush edges, alongside vegetation, log piles etc.). Sampling stations consisted of 5-clustered (n = 150) artificial refuges (ARs). ARs used in this survey were 500 mm x 500 mm corrugated Onduline© sheets (distributed by GBS Group Ltd). Onduline© is an organic, bitumen-saturated material used in reptile surveys throughout New Zealand, due to its light weight and suitable thermal properties (Lettink & Cree 2007, Wilson et. al 2007). ARs were placed out one month prior to inspection to allow time for colonisation by target species. All sampling stations were checked four times (9th, 20th, and 29th January, and 4th February) during the survey period. Site visits for AR checks were under warm (sunny or cloudy) conditions, between 10 am and 12:30 pm.
