DescriptionThe objective of the study was to apply empirically determined hydrology-vegetation models to develop geographic information system (GIS)-based landscape models for three study basins in the New Jersey Pinelands. The landscape models were used to assess the basin-wide distribution of wetland-indicator species and five vegetation types in response to changes in water level as estimated by the various groundwater pumping scenarios. For different groundwater withdrawal rates, "best case" and "worst case" well distribution configurations were implemented. The wetland- indicator modeling suggests that the area dominated by wetland species will decline in area with increased groundwater withdrawal due to the predicted drop in water table.
The landscape modeling suggests that at the higher levels of groundwater withdrawal the decline of wetland area will be especially severe in the upper headwaters of the basins, and that there will be ‘retreat’ of existing wetlands to a narrower streamside corridor. In addition to the predicted decline in area of the various woody wetland vegetation community types, the landscape modeling also suggests that there will be a change in the broader landscape pattern with a simplification of the wetland mosaic with fewer patches.
