Ex situ conservation (where species that
are at risk of extinction in their native
habitat are conserved by growing them in
living collections in botanic gardens or
similar sites) sits within the framework of
the Global Strategy for Plant Conservation
and its 16 Targets, but particularly Target
8 which aims to have 75% of threatened
species held in ex situ collections by
20201. Key factors for success in ex situ
conservation are presence of a range of

Quarterly Operational Report (QOR) for the six months ended 31 December 2019.
The purpose of a QOR is to present a snapshot of the Council progressing through the delivery of the programme of activities
agreed to in that year’s annual plan or long-term plan. It is designed to give a feel for how the Council is progressing and the
forecast for the rest of the year.
This QOR presents the achievement of the programmes of work established by the Council for 2018/2019 in the 2018/2028
the 2015 survey, was not recorded
to have extended beyond the mid-section in the 2018 survey. It has been predicted that hornwort will
eventually become dominant, out-competing E. densa and L. major. While this is not expected to cause
significant impacts on the ecology of Lake Rotorangi or on the hydro-electric scheme, there is now greater
potential for it to spread to nearby lakes, where such impacts could be much more severe, e.g. Lake
Rotokare.

The QOR is structured in the following manner for each activity within each one of the six groups of activity:

The fish populations were sampled using fyke nets (Photo 1) and gee minnow traps. At each site, five gee
minnow traps were set, and baited with Marmite. They were set overnight, among macrophytes or
alongside woody debris. Two fyke nets were also set at each site, a standard mesh (25mm) net and a fine
mesh (13mm). The standard mesh was set downstream, in attempt to intercept any large eels moving up
from downstream. Both fyke nets were baited with fish food pellets. These
confining structures and
aquifer properties below 2000 mm deep were estimated from site visits, the topographic survey
and observation of site staff during construction activities. The influence that aquifer properties
below 2 metres have on groundwater velocities is uncertain, in terms of over and/or under
estimating velocities. For the current groundwater velocity calculations, the aquifer properties were
estimated as 'Silty Clay', with an effective soil porosity of 0. 01 or 1% to the base of the
other KNE's in the
area and is part of the largest block of tall stature vegetation on the
western outskirts of New Plymouth. The site is directly adjacent to
the Upper Mangaotuku KNE.

Sustainability - Positive Key ecological processes still influence the site and with
appropriate management, it can remain resilient to existing or
potential threats.
Other Management Issues
Weeds - High There are very few weed issues in the more mature areas
integrated with the SEM programme to save
duplication of effort and minimise costs. The purpose of annual SEM reports is to
summarise monitoring activity results for the year and provide a brief interpretation
of these results.
Annual SEM reports act as ‘building blocks’ towards the preparation of the regional
state of the environment report every five years. The Council’s first, or baseline, state
of the environment report was prepared in 1996 (TRC, 1996b), summarising the
region’s progress in
context - High Provides well forested cover for tributaries of the Mangapoua
stream as well as additional habitat and greater connectivity with
other Key Native Ecosystems in this area such as the Hickman
Road (Luxton) KNE and Kaipikari Road Forest Remnants KNE.
Sustainability - Positive In good vegetative condition. Key ecological processes still
influence the site. Under appropriate management, it can remain
resilient to existing or potential threats
Representativeness - High Contains
biodiversity.
This leaflet explains why the programme is
needed and how it works, and lists some of
the best ways for land occupiers to maintain
low possum numbers.
Why control possums?
Possums are the predominant pest animal in
Taranaki. They are a major threat because of
the actual or potential harm they do to
agricultural production, animal health and
indigenous biodiversity. They are pests
because they:
Compete directly with livestock
