The active cation exchangeand adsorption capacity of peat (e.g., Gorham 1987),macromolecular aggregates, and Sphagnum mosses(e.g., Ciymo 1963) appearto combine with selectiveionic uptake by Chamaecyparis itself to controlthe water's nutrient content.Measurement of all physica! components ofcedar wetlands will be useful in clarifying the functionsthat control life in an unusual environment. Solittle data have been accumulated that virtually everyobservation would be of both theoretical interest andof utility in management. There are great differencesbetween sites; until more is known, it is inappropriateto extrapolate information from one cedar site toanyothers.The scant research on the chemical compositionof soils and vegetation of Atlantic whitecedar wetlands has not yet produced a clear pictureof cause and effect. This is probably due to the intrinsiccomplexity of relationships which are further obscuredby the differing hydrogedogical, lithdogical,biotic, and anthropogenic components of the sitesexamined.4.6 INTERACTIONS; RESEARCH NEEDEDOther factors not yet measured in cedar wetlandsalso probably play roles in the soil and waterCedar wetland soil chemistry appears to differgreatly from its water chemistry. This may provideaclue to the depauperate chemical contents of cedarwaters. The soil's active ion exchange, and adsorptionprocesses that remove cations from the watermay be part of the mechanism for the accumulationof minerals in Chamaecyparis soil and leaves.
