A number of prominent mounds in the pan area supported a distinct assemblage of taxa (Figure 6) which included Carex paleacea. Potent ilia anserina'' (Silverweed), Triglochin mari- tima (Arrow-grass), Galium labradoricum (Bed- straw), and Festuca rubra (Red Fescue). Third-ridge vegetation on the south transect was more diversified. Scattered shrubs (Salix) were pres- ent and the associated herbaceous vegetation con- sisted primarily of Carex paleacea, Triglochin mari- tima. Potent ilia anserina, and Calamagrostis (C inexpansa, C. neglect a) (Reed-bentgrass). The salt pans were located about 200 m inland from the drift- 'Includes Poientilla egedii.

Evidently tidal water reaches this part of the marsh by flowing through the interridge from the river and creek, possibly during the spring freshet. Many of the pans, particularly those towards the base of the third ridge, were asso- ciated with marginal pools or were flooded entirely. As a result, the vegetation associated with the salt pans was less developed compared to the north tran- sect. Expectedly, Salicornia europaea was rare and A triplex pa tula absent on the south transect. The interridge was relatively dry and surface water was for the most part confined to localized pools.
