Resurvey of the Macroscopic Flora and Fauna of the Upper Laguna Madre


During most of the period from 1951 to 1956 the upper Laguna Madre was strongly influenced by drought conditions which prevailed over the entire state. Reports were prepared showing what conditions prevailed during this period of low rainfall. This drought was alleviated by heavy rainfall in 1957 and 1958 and by March, 1958 the are under discussion was no longer hypersaline. The present resurvey was initiated in order to determine the magnitude of change in physical conditions and the effect of these changes on the flora and fauna of the region. It is not intended to be as comprehensive as the previous survey but rather to lay down a foundation for more specialized projects. However any other future projects should be supplemented by a continuation of the basic survey at least on a minor scale.
