State of the Environment Five Yearly Reports
State of the Environment Report 2009 - 2013
The five yearly State of the Environment summary report 'Hawke's Bay Trends’ is produced by Hawke’s Bay Regional Council so that people have a useful means of assessing longer term changes in their environment and the effect these may have on their lives and businesses.
Underpinning each section of the summary are technical reports which have more detail and data - these can be requested by contacting HBRC's science manager.
This scientific information assists Council with policy and planning, resource investigations and research directions. The summary is also useful for business, other councils, farmers, schools and people involved in environmental work to better understand and plan for their resource care and use.
The printed Hawke’s Bay Trends 2009-13 150 page report is available from HBRC - please contact us on 06 835 9200 for a copy for you, your school or business.
Graphical summary of key points, Chairman’s Introduction and Contents list.
This index will make it easy to find subjects in the Trends report; page numbers are provided for each section to help you cross-reference.
Climate and Air quality – Climate & case studies (p 3-15)
We take a look at circulation patterns and climate trends and how these affect Hawke’s Bay’s weather. Rainfall, temperature, wind and case studies on the drought of 2012/13 and the April 2011 storm (also see the related storm case study under Land p 149.)
Climate and Air quality – air quality & case studies (p 16-35)
What affects our air quality? Find out about air quality in Hawke’s Bay and how we monitor these, plus case studies on the Awatoto industrial airshed, rural PM10 and our 2014 mobile monitoring.
Surface water quality (p 36 – 55)
We take a look at the ecology and water quality in our streams, rivers and lakes and what this means for insects, fish and other habitats. Turbidity/clarity, phosphorus, nitrogen and macroinvertebrate community index investigations are highlighted with case studies.
Surface water – fish and river flows (p 56 -69)
There are 19 species of native fish in Hawke’s Bay streams and lakes – and we can help them out! Find out what our native fish like in a healthy habitat. We look at five years of data on river flows, which were mostly average/above average except the drought summer of 2012/13.
Surface water - recreational water quality & case study (p 70-75)
We look at the results of our long term and summer monitoring of water quality at your favourite beaches. The case study focuses on the causes of poorer water quality at Waipuka Stream at Ocean Beach.
Surface water - lakes & case study (p 76-79)
We look at our lakes and the pest plants and sedimentation that affects them, plus a case study about investigations into Lake Tūtira’s water quality.
Groundwater and monitoring (p 80 – 84)
We monitor groundwater resources, particularly on the Heretaunga and Ruataniwha plains, and are developing geological modelling to increase knowledge in the region.
Long term and seasonal groundwater quantity (p 85-89)
Find out about trends and the interaction of groundwater with surface water.
Groundwater quality & case study (p 90-95)
We monitor groundwater quarterly at key catchments, and the case study looks at nitrogen trends in the Taharua catchment near Taupō.
Land science (p 96-99)
This introduction looks at the way land is used in the region.
Soil quality monitoring & case study (p 100-109)
Learn about our soil quality monitoring programme and the results for Olsen phosphorus, total carbon, anaerobically mineralisable nitrogen, macroporosity, aggregate stability and cadmium. The case study looks at sediment loss on the Tukituki catchment. .
Our riparian environment (p 110-113)
Find out why the riparian – stream side – zone is critical for habitats and water quality. The case study looks at riparian condition in the Tukituki and Heretaunga catchments.
Hawke’s Bay biodiversity (p 114-117)
We look at the state of our region’s biodiversity and threatened species.
The coast, water quality & case study (p 118-127)
Discover more about your coastal environment, and the offshore monitoring we do. The case study explains the data gathered from the HAWQi buoy offshore of Tangoio.
Intertidal reef and sandy beach ecology (p 128 -131)
We monitor the condition of these special coastal areas, so take a close look at the species that live there.
Estuaries & case study (p 132-137)
We monitor estuarine water quality at the Tukituki, Ahuriri, Waitangi and Mohaka estuaries. The case study looks more closely at the estuarine habitat mapping project at Waitangi.
Coastal processes & case studies (p 138-147)
Our coastline and beaches are constantly on the move. Find out about our laser survey of the coastal cliffs, a review of gravel resources and our planning for coastal hazards. Case studies look at the bathymetry survey at Cape Kidnappers, Clifton erosion and the April 2011 storm impacts on the coast.
