coastal land situated on reworked dune
fields. The predominant soil type has been identified as black loamy sand, and
vegetation growth is primarily a mixture of pasture and dune grasses. Average annual
rainfall for the site is 1122 mm (taken from the nearby Glenn Road monitoring station).
Two significant surface water bodies run adjacent to the spreading areas. The Waimate
Stream flanks the north-western side of the main western site, whilst the Rawa Stream
runs adjacent to the north-western
and
rats are increasingly subject to co-ordinated management
by landowners through Council programmes and by other
agencies and organisations. Rabbits, hares and hedgehogs
are also common in the agricultural landscape and while
they can thrive in drier conditions, such as well-drained
sandy soils on the coast, their populations are variable
across the years owing to the region’s relatively high
rainfall climate.

The focus of the strategy however was the establishment of a flood prediction and warning system to
provide warnings to the local community. An automated warning system was subsequently developed
and an additional telemetered rainfall site installed in the Ngutawera sub-catchment to assist with these
warnings.
In regard to river channel management, the Strategy recommended that arrangements be made in

(a) stormwater runoff is prevented from
estuaries such as the Tongaporutu, Waitara
and Pātea rivers, and the confines of Port Taranaki.
The Taranaki region has a temperate climate with
generally abundant rainfall. The incised nature of
ring plain streams means that flooding is not a
major problem. However, occasional intense rainfall
events can lead to rapid rises in river levels and
flooding in hill country valleys and elsewhere.
