WCC SNA Botanical Ground-truthing of the Wellington South Coast 2021/22 - Surveyed by 7(2)(a) – RESTORE
Scope
Wellington City Council (WCC) contracted 7(2)(a)
RESTORE to improve the accuracy and capture of
ecological values within the Wellington’s South Coast - Te Kopahou SNA to support better management of
these sites by WCC officers. In particular to ground truth SNAs and produce a more detailed inventory of
the significant ecological values, identified within the larger sites.
Methodology
The general approach for surveying the area was to start at Sinclair Head at the Western most extent of
the site and work back toward the car park area on the eastern boundary of the site. A transect of sorts was
travelled along recording all species of interest seen as well as recording locations of interest using a GPS
unit. The ‘transect’ is not completely linear as the substrate, vegetation and terrain depicted dictated where
could be surveyed safely and thoroughly. For example, large swathes of gorse were not investigated due
inaccessibility.
The SNA was visited 18 times during this survey from July 2021 to February 2022. Due to weather and
time constraints, a mixture access points and timings was used to complete the survey.
Species were reported according to their Regional Threat Classification (Crisp, 2020), or National Threat
Classification (de Lange
et. al., 2018).
Specific Site Descriptions (Zones)
The SNA was split into various zones based on their geomorphology as illustrated in Map 1. Further details
of each zone are highlighted in the following sections. Each species list was recorded as per zone and can
be seen in the accompanying spreadsheet ‘Te Kopahou South Coast Survey Species Data’.

CLIFF
This only includes the area directly west of the Te Kopahou carpark as it is relatively unique in its steepness
and location. This is a very small zone which did not take much evaluation.
COAST
This includes habitat at the base of the slopes which may been dune, unworked scree, and beach. A couple
of seeps are also present. Scree fans were also included in the ‘coast’ zones due to the general gradual
slope and composition of substrate being weathered greywacke.
STONE STACKS
Any rock stacks seaside of the access road, including any sea surrounded rocks as long as vegetation is
present and able to be identified.
QUARRY
This encompasses the area formally used as a quarry. This area is artificially modified to include steeper
than usual bedrock faces, as well as flat(ish) platforms. This type of habitat is unique in the survey area.
RIPARIAN
These sites are the area directly near and affected by a stream. The likelihood of substrate which may be
affected either positively or negatively by constant water supply. Areas like this can also have a higher
humidity than sites nearby which may allow species to thrive that would not otherwise.
CATCHMENTS
Two catchments (Raurekau Falls and Taumata Patiti Pa) were added to the survey after initial feedback
was given. Both areas have riparian zones at their floors which lead to the sea on the South Coast. Each
catchment is quite unique as their output is very seasonal and remarkably contained compared to the
greater area.
SLOPES
The majority of the site is regarded as slope, yet some differentiation can be made. The slopes have been
divided into three types dependant on orientation; South-West, South, and South-East. The slopes are
steep and are generally composed of rocky outcrops surrounded by either stable or unstable scree.
Pest Animal Sign
14/7/21 – During survey of Sinclair Head a lot of pig routing and scat was noted. Saw a live possum in
SWS1 toward the top edge intersection which ran as soon as it saw me. Some of the lower slope
Aciphylla
squarrosa ssp. squarrosa showed signs of being nibbled by deer/hare/rabbit.
Most of the
Pimelea sp. appeared to be targeted by rabbit/Hare, leaving a small remnant of the plant alive
but in poor health.
23/7/21 - Possum seen on true left of lower section (R4) bank of Raurekau Catchment.
11/8/21 – Live possum seen on Eastern edge of Raurekau Falls Catchment, at top of lower branch to
tributary R2. Two rats ran across my note board as I pushed through some vegetation at the bottom of the
true left tributary of Raurekau Falls catchment.
24/9/21 – Live possum seen sleeping in the rotting remnant of a
Phormium sp.
29/9/21 – Live possum ambled off in front of me at top of eastern edge of SES3.
15/10/21 – Live Hare seen in terraced area above Red Rocks (SWS2). Live possum seen living/sleeping
under
Coprosma propinqua in Northern section of the Taumata Patiti Pa catchment
9/2/22 – SES1/SWS3/SFS - Three live possums seen during this day’s survey. All seemed pretty relaxed
with my presence to the point I managed to take photos. There was lots of rabbit scat present in the SES1
area.
In the zone SWS3 in the upper reaches particularly there was a lot of pig scat, so much so it felt as if the
area was where they might reside. There were a couple of flattened out areas of vegetation.

Riparian Zone – 3 Areas
Surveyed - 12/7/21, 20/7/21, 23/7/21, 15/9/21,
11/12/21.
These three areas all had running water at the
time of survey and were delineated from
surrounds by the eroded environment either side
of the flowing water.
R1 - Hape Stream - This stream is encountered
as soon as you travel into the Te Kopahou
Reserve and was not specified as an area
needing survey as it has been thoroughly
surveyed in the past. The lower section was
surveyed to gather a species list which could be
compared to those from the other two streams
surveyed.
R2, R3, R4 - Un-named Stream to Whare-
Raurekau (Figure 2.) - Running North to South,
a steep un-named waterway utilised by the
baches on the old site of Whare-Raurekau
(Adkins, 1959) nearby as a water supply. The
area has steep cliff-like sides and a series of
waterfalls, which at time of first visit had a
reasonable amount of continuous flow. Several
steps of smaller grade rock material flatten the
span between each side of the waterway. Directly
below the waterfall larger grade rock material is
evident and potentially relatively newly placed.

Coast Zone – 3 Areas
Surveyed - 20/7/21, 4/8/21, 15/9/21, 18/11/21.
This area has been divided into three sites in the
survey area, (Map 1).
Co1 - Encompasses the area from the carpark
to just beyond the first baches. This area
includes some restoration plantings which make
it somewhat different from Co2 & Co3.
Co2 - Is the zone from just past the first batches
to Pariwhero – Red Rocks and is South-East
facing. It also includes the lower section of a
stable scree fan
Co3 - Includes the zone from Pariwhero – Red
Rocks to the end of the survey site at Sinclair
Head, including the Seal haul out area.
This zone is the most accessible and dynamic.
Tides and human interaction continually shape
and reshape this zone.
• During the visit on 18/11/21 numerous
lizards (skinks) were seen darting away
as I recorded the plants.

29/9/21, 29/10/21, 10/11/21, 18/11/21, 24/11/21,
9/2/22.
In total these 4 areas make up the largest part of
the survey (Map 1).
SES1 – This area is from the Quarry to east of
the first baches below Raurekau Falls.
SES2 – This is the smallest of the 4 areas and
was particularly difficult to survey. It is the slope
above the R4 section of the lower part of the
Raurekau Falls.
SES3 (Figure 5.) – This is the largest single
section of the survey. The area starts at the
western edge of the Raurekau Falls Catchment
and extends to the point formed by Red Rocks.
SES4 – This area is on the eastern slope of
Sinclair head and is bordered by the Taumata
Patiti Pa Catchment.
• A native NZ Falcon was seen speeding
past early in the day of 9/2/22.

Raurekau Falls Catchment
Surveyed - 23/7/21, 31/7/21,
11/8/21, 24/9/21, 29/9/21,
24/11/21, 9/2/22.
This area was a late addition
to the survey area due to its
uniqueness in being a small
catchment
feeding
the
Raurekau Falls. This water
is the supply used by the first
group
of
baches
encountered on the coastal
trail. Figure 6 (next page)
shows the area contains two
tributaries detailed on Map
1, as R2 and R3.
The
eastern
west-facing
slope has dense vegetation
of
mahoe,
gorse,
and
Coprosma propinqua, and is
quite slow to manoeuvre
through.
The
southern

section of the western side
terrain and catchment area.7(2)(a)
of the catchment has a large
area of impenetrable gorse which needed to be detoured below then back up to survey the vegetation on the
other side of it.
The tributaries are well vegetated towards their upper reaches, the lower section is sparsely vegetated before
dropping off into the fall’s valley.
• Numerous skinks were seen on the upper exposed stony slopes of the East-facing Western section
(24/11/21).
Threats
• Pig-sign is relatively common in parts of this catchment, either below the canopy on the east, or in the
open areas of lower section towards the Falls. In the east the understory was lacking due mainly to the
consistent routing. The west section also has large swathes of excavated substrate below the
shrubbery.
• Possums (live) were seen several times during this survey.
• Rats were encountered on one occasion possibly suggesting high numbers.
Species
Exact locations of the species in the following tables can be found in the accompanying document ‘WCC South

Taumata Patiti Pa Catchment
Surveyed – 15/10/21, 21/10/21
This area was a late addition to the survey area
due to its uniqueness in being a small
catchment feeding the historic Taumata Patiti
Pa site west of Waipapa Stream. This water is
the supply used by the last bach encountered
on the coastal trail. The area contains two
tributaries detailed on the map as R5.
A rudimentary track has been formed which is
why I was asked to survey this area as it
provides an entrance point for human
introduced weed species. The eastern west-
facing slope has dense vegetation of gorse and
Coprosma propinqua and is quite slow to
manoeuvre through unless a clear path is
chosen. The tributaries are mostly dry until
towards the steeper walled valley begins below
their confluence.
Threats
• The area appears to have very few
Berberis darwinii, which could be
successfully controlled.
• Gorse in present but mostly in patches
which may be a consideration for
control.
• A single patch of
Polypodium vulgare

South Facing Slopes Zone – 2 Areas
Surveyed – 15/9/21, 24/11/21, 9/2/22.
This zone comprises of two faces either side of
the Raurekau Falls riparian intersection with the
coastline. Both slopes are particularly steep as
can be seen in Figure 7.
Both areas were surveyed mostly from below or
above as the slope terrain was not safe to
traverse.
Threats
•
Coastal erosion is the only likely issue
for these 2 areas, yet both areas are
some height above the high tide mark
for now.
•
Human interaction may prove a
problem in time as they are above
baches.
•
Gorse is present in large volumes and
not safely controllable.

Surveyed - 14/7/21, 15/10/21, 18/11/21, 9/2/22.
Differentiated from the majority of the slope
habitat by the fact these slopes face south-west
which ensures they receive more sunshine hours
than others, especially whilst the sun curvature is
lower during the winter months. (may be
interesting to see what differences there are with
species composition).
SWS1 – This area is represented by the western
most extent of the SNA survey, this is the sunny
side of Sinclair Head (Figure 8.).
SWS2 – The sunny slope above Red Rocks from
the ridgeline to Waipapa Stream’s eroded east-
side.
SWS3 – The small sunny patch above the
Raurekau Falls Riparian area R4.
Threats
