Fire History of the Region
Human-caused wildland fires occur annually in Guam and the inhabited Northern Mariana Islands - Rota, Saipan, and Tinian. Fire has been identified as a key threat to communities, forest resources and watershed integrity in the 2010-2015 Statewide Resource Assessment and Strategies for both regions. Fire records on Guam from 1979-2000 show that an average of 730 fires per year burned 4,800 acres (1,942 ha), or c. 4% of the island's total land area. Annual fire number and area burned increased in years following El Niño events.
The cause of the majority of fires is attributed to intentional burning, typically related to hunting activities. In addition, fire-prone savanna vegetation accounts for 17-23% of the main islands in the Marianas chain. Fire occurrence is most frequent during the pronounced dry season from December to June.
Guam & CNMI Fires
The US Forest Service’s Pacific Island Research Center’s Julian Dendy has mapped the extent of wildfires from 2015 – 2022.
Recent Resources for the Western Pacific
In this joint webinar hosted by the Pacific Fire Exchange and the Pacific Regional Invasive Species Climate Change, we tackle the climate crisis in Hawai`i and how this affects the risk of wildfire as well as the impacts to people and the archipelago’s unique resources.
Talk Story Tuesdays: Informing Contemporary Wildfire Science from Historical Hawaiian Language Newspapers
In this Pacific Fire Exchange talk story Q&A session, we speak with Dr. Clay Trauernicht and Dr. Alyssa Anderson, University of Hawai`i at Mānoa about wildfire in Hawai`i in the context of Hawaiian language newspapers as well as the historical landscape changes of the 20th century.
In this Pacific Fire Exchange talk story Q&A session, we round up the latest research, past and present for managers and landowners wanting to understand more about how our four-legged friends (goats, sheep, cows, etc.) if managed properly can help reduce blazing and wildland fire. This month’s science share out and conversation was with Dr. Clay Trauernicht, University of Hawai`i at Mānoa Ecosystems and Fire Specialist; Raia Olsen of O‘ahu Grazers and Dr. Elliott Parsons, formerly with the Department of Land and Natural Resources. They presented the how-tos on hiring island professional grazers and lessons learned for contract grazing.
