Adding excess nitrogen to natural aquatic environments can have detrimental effects. Detrimental effects include impairing animal survival, growth, reproduction, and excessive plant growth.
The dataset - What is it?
View details on the minimal standard required in various water bodies, set by government policy. In respect to these policies see the current degree of compliance. You can view the total nitrogen load (TN) and exceeding the maximum allowable load (MAL) on a map of New Zealand.
Why it's important
Freshwater policy sets maximum allowable loads for nitrogen in catchments. While policy and associated limits may change over time, it is generally accepted that many regions across Aotearoa (43% in 2023) are currently operating in excess of the maximum allowable load. Therefore, either changes in land use or land management practice are required in order to bring total nitrogen loads down.

Caveats
The study has used all the available data. Therefore, it would be difficult in most catchments to improve on the analysis. However, because the models were all national in extent, there may be a degree of model bias when the results are applied at fine scales.

Please note:
You can use this information to help form an understanding of the nitrogen pressures within your region and your catchment. This may help you when assessing land use options in the context of kaitiaki responsibilities.
