  • rodent
  • The porcupine is a caviomorph rodent whose ancestors rafted across the Atlantic from Africa to Brazil over 30 million years ago, and then migrated to North America during the Great American Interchange after the Isthmus of Panama rose 3 million years ago. (wikipedia.org)
  • The largest European and African rodent, the African crested porcupine (Hystrix cristata), attains a length of c. 80cm (31in). (encyclopedia.com)
  • wildlife
  • Porcupine1: NRVP participants Greg Moore, Mike Maulhardt, Charles Brown and Ben Smith volunteered to service and maintain porcupine stations at Red Lake Wildlife Area. (ca.gov)
  • But in her conversations with unit biologists and wildlife officers in some of these areas, Anderson took note that many were reporting a substantial decrease in the number of calls from residents whose property - typically wood structures such as decks and outhouses - had been damaged by porcupines in recent decades. (ca.gov)
  • long
  • Recognizing the need to gather more information, Anderson and Evan King, another CDFW environmental scientist, launched a pilot effort last year to improve surveillance of porcupine, with a long-term goal of determining distribution and population numbers. (ca.gov)
  • Anderson and King were inspired by the work of Uldis Roze, a researcher who has long studied porcupines in the Catskills of New York by using wood soaked in salt brine as a porcupine attractant. (ca.gov)
  • fall
  • Porcupines fall out of trees fairly often because they are highly tempted by the tender buds and twigs at the ends of the branches. (wikipedia.org)
  • begin
  • A female porcupine will begin breeding at 15 months and will have a single precocious offspring each year in late spring. (maryland.gov)
  • show
  • His research indicates that porcupines show a strong seasonality of salt use, which peaks in April through May and August through September. (ca.gov)
  • Seven
  • Perhaps most telling, CDFW's Sierra Nevada monitoring project, which has studied portions of the Sierra for the past nine years, has documented only seven porcupine sightings out of 750 stations surveyed via trail camera. (ca.gov)
  • common
  • By far the most common is E. d. dorsatum , which ranges from Nova Scotia to Alberta and from Virginia to the Yukon. (wikipedia.org)
  • Although
  • Preliminary results indicate that the brined wood appeared to lure porcupines into the area of a camera station -- although most did not approach the wood and fewer still left a distinctive chew mark on the brined wood. (ca.gov)
  • often
  • However, because of the damage caused to property, including trees, crops and car tires, porcupines are often hunted or trapped. (iucnredlist.org)
