Higher temperatures and increases in vapor pressure deficit (VPD) can influence fire risk by drying fuels, thus making them more flammable and prone to ignition ( 10, 17, 18).

A third key potential driver is climate change, with observations providing evidence of hotter, drier conditions during summer and a longer fire season ( 12, 15– 17). Concurrently, population growth and housing development have increased, particularly in lower elevation foothills, potentially increasing the frequency of ignition in and around the wildland-urban interface ( 12– 14).

Fire suppression and land-use change have been considered primary drivers as they have led to denser, more flammable vegetation with a more connected landscape for fire spread ( 8, 11). An improved attribution of the recent increase in burned area is needed for better predictions of future fire activity and for the design of forest management strategies but remains challenging given the wide range of possible drivers and the interactions among them. Over the past few decades, fire occurrence and burned area have increased considerably in the Sierra Nevada ecoregion ( 3).
During the 21st century, changing climate is expected to further modify ecosystem structure and function, and a key challenge is to understand how the fire regime of the Sierra Nevada will evolve in response to warming. There is a general consensus that these changes contributed to a new fire regime of infrequent, high-intensity fires that was prevalent during the middle and latter half of the 20th century ( 4, 8– 10). Early and mid-20th century fire suppression policies also shaped the fire regime, causing vegetation composition and structure to shift over time ( 6, 7). settlers and in the mid-19th century by the California Gold Rush, which contributed to deforestation and heavy livestock grazing across the region ( 2). This fire regime was altered by the loss of indigenous peoples caused by waves of Spanish, Mexican, and U.S. During the Holocene, fire management by indigenous peoples led to a fire regime with frequent and low intensity fires, often with a return interval of less than 20 years ( 1) and yielding outcomes that improved the efficiency of resource gathering and other ecosystem services ( 4, 5).
