The largely undisturbed upper catchment is in excellent condition and managed as State Forest, with control of weeds being the main concern. In contrast, the floodplain has been extensively cleared for grazing and is generally in poor condition.

The Nicholson River has an extensive estuary reach that extends from the Great Alpine Road bridge at Sarsfield to where the river enters the Gippsland Lakes at Jones Bay. There are several important wetlands on both sides of the river, the largest being Bosses Swamp and Nebbor Swamp.

These wetlands are part of the Gippsland Lakes Ramsar site which is listed as internationally important under the Convention on Wetlands (Ramsar, Iran, 1971).

The Nicholson River is relatively short, so the potential to link the Gippsland Lakes with the forested areas in the upper catchment is greater than for other rivers.
