Nebraska Growing Lands Coalition summer grazing tour called “Resilience and Resurgence: Rejuvenating Landscapes after the Cooksley Complex Wildfire” will be held on June 12, 2024 in Anselmo, Nebraska. Tuesday, June 11, 7 p.m. a special.
The 2019-20 bushfire season impacted a range of ecosystems across Australia, including several coastal vegetation types that have not been subject to burning historically. In the Clyde River estuary of southern New South Wales (NSW), mangrove species Avicennia marina and Aegiceras corniculatum were burnt in the Black Summer bushfires. The slow recovery of these poorly fire adapted species reflects the lasting impacts of the event. This study aimed to quantify the ongoing processes, patterns, and capabilities of post-fire mangrove regeneration for both species in the Clyde River estuary. Assessments of fire-affected mangroves were undertaken through field data collection and analysis of remotely sensed aerial imagery. Long term study site Chinamans Point exhibited limited resprouting of severely impacted A. marina, for the third year of monitoring. At Mays Road and Buckenbowra entrance, change detection analyses suggested only 19 – 28% of the total defoliated mangroves exhibited regr
Aim: Megafire events generate immediate concern for wildlife and human well-being, but their broader ecological impacts likely extend beyond individual species and single fire events. In the first mechanistic study of fire effects focussed on ecosystems, we aimed to assess the sensitivity and exposure of ecosystems to multiple fire-related threats, placing impacts in the context of changing fire regimes and their interactions with other threats. Location: Southern and eastern Australia. Time period: 2019–2020. Major species studied: Australian ecosystems. Methods: We defined 15 fire-related threats to ecosystems based on mechanisms associated with: (a) direct effects of fire regime components; (b) interactions between fire and physical environmental processes; (c) effects of fire on biological interactions; and (d) interactions between fire and human activity. We estimated the sensitivity and exposure of a sample of 92 ecosystem types to each threat type based on published relationsh
