    Abstract This report presents the findings of habitat mapping undertaken throughout the Hutt Estuary in January 2016. This mapping exercise documents the key habitats and substrate types within the estuary with a view to monitoring the changes to their areal extent over time. Results of the 2016 mapping indicate there is a high risk of adverse impacts to the estuary ecology due to loss of important habitats such as saltmarsh and a degraded subtidal habitat.
