Hawaiian Monk Seal Research

The Hawaiian Monk Seal Research Program (HMSRP) works to enhance the recovery of the Hawaiian monk seal by studying their biology, ecology and natural history. The HMSRP monitors and assesses the six main monk seal reproductive subpopulations in the Northwestern Hawaiian Islands (NWHI) as well as the increasing subpopulation in the main Hawaiian Islands (MHI). In addition, the HMSRP investigates threats to Hawaiian monk seal survival and works to mitigate factors impeding the species recovery. More...
