The report provides an evaluation of the general characteristics of the Delaware Inlet and its contributing catchment and includes: 1. A compilation of background information relevant to the ecological condition of Delaware Inlet, 2. A digitised historical vegetation map of Delaware Inlet (1983), and 3. A preliminary ranking of the ecological status and values of Delaware Inlet - Decision Matrix. Range of depth: < 1.2 m neap tide to> 4.2 spring tide. Modifications to the Delaware Inlet and its contributing catchment include: Conversion of previously forested land for agriculture post-European settlement; potential enrichment effects from introduced nitrogen-fixing vegetation and addition of pasture fertiliser; conversion of large catchment areas to pine plantation and subsequent harvesting and effect on sediment; effect of the development of roading and flood control; adverse effects related to reduced water quality; the invasion and spread of the exotic bivalve Crassostrea gigas (Pacific oyster). Actions required include: broad-scale habitat mapping and fine-scale assessment of individual reference sites; use of standardised methods for comparison with other estuaries in the region and serve as a point-in-time baseline for future monitoring; need data describing water and shellfish faecal indicator concentrations in Delaware Inlet.

A survey was made of the local environment and flora and fauna of Delaware Inlet, Nelson, during February-April 1976. Extent of site = Delaware Inlet. Measured variables = Five textural surfaces (mud, sand, gravel, cobbles, and shell). Five principal types of macroscopic vegetation (Salicomia ausiralis, eelgrass Zostera muelleri, Sea lettuce Viva lactuca, Enteromorpha). The four dominant genera of molluscs (mud snails Amphibola crenata, cockles Chione stutchburyi, pipis Paphies australe, mussels Mytilus edulis) occupying distinct habitats. Water parameters (salinity, nitrogen). Depth range: 2 m (neap) to 4 m (Spring tide). Sampling protocol = mapping.
