Every year, the Northcoast Marine MammalÂ Center responds to hundreds of distressed animal reports along the coastline of Humboldt and Del Norte counties. Most of the reports come from members of the public who share our concern about the wellbeing of marine mammals in our area. The NMMC has dedicated volunteers who are trained to assess the health of stranded marine mammals. After assessment, most frequently animals are rescued and transported to the NMMC for rehabilitation. However, sometimes animals are put on 24-hour watch and volunteers return the next day to assess the animalâ€™s condition. During harbor seal pup season, volunteers return every few hours to monitor the condition of pups and whether the pup has been reunited with its mother.
