Further exploration of the Cockscomb Basin did not transpire until 1927, when further British expeditions were launched to assess timber reserves; subsequently, logging began to occur until the year 1984, primarily with extraction of cedar ("Cedrela odorata") and mahogany ("Swietenia macrophylla"). At about the same time as exploitation of these resources was virtually complete, a nationwide study of the jaguar was initiated. This scientific investigation led by Alan Rabinowitz, a recent recipient of the PhD degree from the University of Tennessee, found that the Cockscomb Basin was a particularly important habitat for the jaguar, not only in Belize, but from a Central America perspective.
