Comparison of vesicular-arbuscular mycorrhizae in plants from disturbed and adjacent undisturbed regions of a coastal salt marsh in Clinton,Connecticut, USA

Roots of salt marsh plant speciesSpartina alterniflora, S. patens, Distichlis spicata, and others were examined for the presence of vesicular-arbuscular mycorrhizal (VAM) fungi. Samples were taken from introduced planted material in a salt marsh restoration project and from native material in adjacent marsh areas along the Indian River, Clinton, Connecticut, USA. After ten years the replanted area still has sites devoid of vegetation. The salt marsh plants introduced there were devoid of VAM fungi, while high marsh species from the adjacent undisturbed region showed consistent infection, leading the authors to suggest that VAM fungal infection of planting stocks may be a factor in the success of marsh restoration.     

TIME LAPSE AERIAL PHOTO ANALYSIS OF THE CONNECTICUT RIVER FROM 1952 TO 19651

Aerial photogrammetric techniques were developed and tested for identifying and classifying river-based recreation sites. A classification system was designed to describe the nature of the land itself, the land use, or the vegetation on the landscape. The Connecticut, a large river running through four states, was examined and classified using the system. Analysis of two sets of aerial photographs taken with a time lapse of ten to thirteen years enabled determination of past use and development trends. A catalogue of maps classifying strips of land adjacent to the river was prepared and reproduced for use by interested planning agencies. Statistics on land area by types for the river as it now is and as it was ten to thirteen years previously have been prepared by towns, counties, and states. The aerial photographs proved invaluable for analyzing the recreational potential of the Connecticut River.
