Porcupine populations may be declining in California. We are interested in any porcupine sightings in California within the past 10 years. Porcupines are generally found in coniferous and mixed forested areas. Porcupines are slow-moving nocturnal herbivores that range from 2-3 ft long and are covered in quills. Porcupines spend most of their time in trees feeding and resting. This information will be used to initiate a study on trends in porcupine populations in and around Humboldt County. Thank you for your participation! If you have any questions about the study, please contact Nadia Sureda (
) MSc student, University of Edinburgh. Tim Bean (
), Assistant Professor of Wildlife at Humboldt State.
