Appendix to a report on vegetation succession and wildlife use of dredged material islands in New Jersey containing historical wildlife data for the the New Jersey study area.

From abstract: Geologic and aeromagnetic data show that a major tectonic unit underlies rocks of the Musconetcong nappe in the Great Valley of eastern Pennsylvania and New Jersey. This structure, the Lyon Station-Paulins Kill nappe, can be traced from Lyon Station, Pa., at least to Branchville, N.J., a distance of about 120 km. The nappe has a core of Precambrian crystalline rocks as shown by an aeromagnetic anomaly that has the same signature as the outcropping Precambrian rocks of the Musconetcong nappe. This core extends at least 70 km east from Lyon Station to Bangor, Pa., the eastern limit of the aeromagnetic survey. This report details the frontal structure of this system.

Abstract: Chemical and microbiological data from four characteristically acidic streams in southern New Jersey were used to evaluate seven factors related to the proclivity of each stream to nitrify under the influence of secondary sewage effluent. pH, water temperature, and dissolved oxygen were used as indicators of a stream conditions while neutralization of alkalinity, nitrogen species trends, BOD/NOD incubations, and nitrifying bacteria densities served as actual nitrification indicators. Hay Stack Brook showed strong evidence for nitrification on the basis of all four nitrification indicators while Landing Creek was nitrifying little if at all. Hammonton Creek is apparently nitrifying, but because of uncertainty in the downstream trends of the nitrogen species, and a lower level of alkalinity neutralization, it is nitrifying less than Hay Stack Brook. Squankum Branch showed some evidence for nitrification on the basis of the BOD/NOD incubations. The acidic character of these streams does not appear to be an exclusive factor in determining whether the stream will undergo nitrification.

This study was funded by NAPEN to aid in evaluating proposed modifications. Plans of improvement for New Jersey inlets and beaches were presented by NAPEN in a Navigation and Cooperative Beach Erosion Control Study.

This report summarizes the results of investigations of the distribution of colonial seabirds and wading birds on New Jersey dredged material islands, of vegetation distribution and succession on dredged material islands, and of the interactions of vegetation and birds on dredged material islands.
