substrate composition and grazer density influence periphyton growth.
Periphyton is measured by the concentration of chlorophyll-a per square metre (a pigment that plants use
for photosynthesis). Periphyton is also measured visually so that it can be compared to guidelines for
ecological health or aesthetic values. Weighted composite cover measures the combined cover of some of
the less desirable forms of periphyton, such as long filaments and thick mats. Monitoring is carried out
where
response is based on the traffic light system
of Green, Amber or Red and we can qualify the response with commentary if
needed.
• One of the “risks” we identified in the monthly report is time. This project has to be
completed by 30 June 2024 but we are being slowed down by Waka Kotahi
processes.
• We will have to bend the procurement rules to meet this very tight timeline. We do
not have time to go through the traditional procurement processes of tendering and
award, this assumes there
in a number of forms (nitrate, nitrite, ammoniacal nitrogen and organic
nitrogen). The most common sources of nitrogen include leaching and run-off from agriculture and
horticulture or from industrial or wastewater discharges.
Ammonia (toxicity)
Ammoniacal nitrogen (NH4-N), also called ‘ammonium’, is the concentration of nitrogen present as either
ammonia (NH3) or ammonium (NH4) in water. The balance between ammonia and ammonium depends on
the pH and temperature of the

Section 2 | Significant Projects
A significant project is defined as one that, alone or in combination with other
concurrent projects, is anticipated to cause sustained work impacts greater than
what is considered tolerable for delivery within existing TEMO resources.

ecosystem health (Clapcott et al, 2017). They play
an important role in the stream ecosystem food web and are influenced by the physical, chemical, and
biological conditions of the stream. They also respond to changes in variables including, but not exclusive
to, water quality, flow, stream habitat, and invasive species. Thus, they are capable of showing the impacts
of stressors present upstream in the catchment, such as habitat loss or pollution (NEMS, 2022). For example,

Essential
freshwater rules
All you need to know
Many of the regulations around freshwater and how we manage
this precious resource have changed or are changing. These
changes are being driven by the Government’s Essential
Freshwater reform package. This booklet provides a quick
guide to all the rules.
There are more in-depth information and factsheets to download at
25% by 2033.

third.
80% of respondents would like to travel
more actively (through walking, cycling
etc.) as part of their daily lives.
There’s a concern about road safety in
the region, and many people are willing to
trade off faster travel journey times for
improved levels of safety.
Many people would start using the bus,
or use it more, if

high concentrations, ammonia and nitrate can be toxic for aquatic life.
Phosphorus can be present in water in different forms, and is an essential nutrient for instream plant life.
Most phosphorus enters rivers attached to sediment. Phosphorus is naturally elevated in our region’s soils
due to the volcanic geology however, fertiliser application along with the discharge of domestic and animal
waste also contribute to elevated

Schedule 2 – Coastal areas of outstanding value
This schedule identifies eight areas of outstanding natural character and nine areas that are outstanding natural features or landscapes. A values table and map for each area is included
below. Information included within this schedule has been informed by the report Regional landscape study

Overview of Suspended and Deposited Fine Sediment
Sediment is mineral or organic matter that is transported by water, air or ice and is the result of erosive
processes. The magnitude of erosion is a function of climate, vegetation, soil type and topography.
Sediment delivery to aquatic systems can be viewed as a function of the interactions between natural
environmental variability, and land management decisions that
