Interactions between vegetation and climate over extended periods establish a particular pattern of wildfire recurrence in a defined ecosystem, known as its fire regime. Deviations from the prevailing fire regime – the timing, frequency, size and intensity of wildfires – can drive significant ecological changes in both fire-dependent ecosystems that need fires to thrive and fire-sensitive ecosystems where fires bring more negative than positive effects.Full report is available at: https://wedocs.unep.org/handle/20.500.11822/38059 NO https://www.unep.org/resources/frontiers-2022-noise-blazes-and-mismatches DS UN Environment Document Repository RD Sep 19, 2026
