The relatively new Evans Bay site (Evans Bay 2) was introduced to the monitoring programme in 2016. It is located in south-west Evans Bay, offshore of Hataitai Beach. This site is unusual among the Wellington Harbour sites in both sediment community diversity and sediment type. Reasons for these differences include: the distance from Te Awa Kairangi / Hutt River, which limits the transport of silt to this area; the shallowness of the site (only 7 metres deep), which makes the area more prone to wind driven resuspension of fine sediments; and the persistent historical sedimentation patterns in Evans Bay following the uplift of the Rongotai Isthmus.
Thirty species found at EB2 are not present at any of the other sites likely reflecting the coarse, diverse nature of the substrate. The dominant animals are worms and small hopper.
