The NEOFire team has now finished another experimental fire campaign at Serra das Araras! This is the 8th consecutive year we burn savanna plots to investigate the effects of altered fire regimes on the Cerrado

10) Finally, @manumachadoeco.bsky.social closed the symposium by talking about developing a new Cerrado degradation framework. Because degradation is typically addressed as loss of biomass in forest ecosystems, her aim is to redefine and quantify degradation within the open landscapes of the Cerrado

9) More broadly, Vera Arruda from @ipam-amazonia.bsky.social presented her work analysing fire regime changes in the Cerrado biome from 1985 to 2022 (using Landsat satellite imagery from the @mapbiomas.bsky.social Fire Collection 2). She focused on recurrence, land-use distribution and area of fires
July 7, 2025 at 11:27 PM
8) Paulo Bernardino then talked about the use of multispectral and thermal drone imagery to map Cerrado wetlands, focusing on identifying the optimal spatial resolution for accurate classification at Chapada dos Veadeiros. He highlighted the potential of upscaling wetland mapping with satellite data
July 7, 2025 at 11:27 PM
7) @tashlutz.bsky.social then talked about her work developing a novel method to estimate fuel loads across the Cerrado using a multi-scale data fusion approach. She is quantifying structure and accumulation of surface, herbaceous and woody fuels, providing insights into fire impacts and probability
July 7, 2025 at 11:27 PM
6) After lunch, @alefidelis.bsky.social re-opened the session by talking about the history of fire management in Brazil. She described the fire experiment at Serra do Trombador and its many cool results, highlighting the importance of long-term collaboration and integration with non-academic actors
July 7, 2025 at 11:27 PM
5) Prof Vânia Pivello from USP closed our morning session. She spoke about the use of fire as a management tool to stimulate the flowering of Eriocaulaceae by traditional harvesters at Sempre-Vivas National Park, where late-season fires result in slow recovery of plant cover, composition and height
July 7, 2025 at 11:27 PM
4) Prof Reuber Brandão from the UnB presented his team’s research on the role of termite mounds as wildlife fire refuges in the Cerrado. Because temperature and humidity in termite mounds remain constant during fire, they can hold up to 71 individuals from 14 species of reptiles and amphibians!

3) I then presented the results of my second PhD chapter investigating how the fire regimes at Serra das Araras influence woody productivity of Cerrado trees; and how productivity responses are explained by bark protection and photosynthetic functional traits at high fire intensity @biology.ox.ac.uk
July 7, 2025 at 11:27 PM
2) Wesley Cruz then presented the research he has led within the CERFogo Team, looking at ecological strategies of trees in response to experimental burning (focusing on resprouting dynamics across regimes and traits influence on tree fire tolerance, recently published at doi.org/10.1002/ajb2...)
July 7, 2025 at 11:27 PM
1) The symposium was opened by @ioliverasmenor.bsky.social who introduced the conservation challenges of altered fire regimes in the Cerrado and presented an overview of the CERFogo project at Serra das Araras (aiming to monitor the long-term use of fire as a strategy for biodiversity conservation)

Last week, the @oxfordecosystems.bsky.social team and I participated in the ATBC2025 meeting in Oaxaca, México. It was great to see so many cool research presentations! During the event, @manumachadoeco.bsky.social and I organised a symposium about Cerrado fire ecology and conservation (see thread):

Finally, I would like to thank my coauthors/collaborators, especially #ICMBio and #UNEMAT for their support in fieldwork and burning (6/6)

Third, fire affected the total ecosystem balance by reducing aboveground flux allocation and carbon use efficiency. Our results suggest reintroducing fire causes encroached plots to release carbon as open structure is restored. We find burning is a successful strategy for savanna conservation (5/6)
June 4, 2025 at 9:27 PM
Second, trends of change as a result of fire varied across the different ecosystem components. Patterns of change were linked either with fire frequency or fire intensity. In other cases, fire effects were hard to identify, warranting research into below-ground and ecophysiological dynamics (4/6)
June 4, 2025 at 9:27 PM
First, we found that fire reduced woody vegetation cover and density. Trends in ecosystem structure were supported by reduced carbon fluxes associated with trees. Burnt areas are transitioning towards grass-dominated systems, reverting the woody encroachment caused by past fire suppression (3/6)
June 4, 2025 at 9:27 PM
For the first time, we were able to provide detailed estimates of canopy, stem, herb, root and soil carbon fluxes within cerrado sensu stricto. We compared fluxes unburnt plots with those in plots burnt at one, two and three year intervals. This allowed us to obtain three main findings (2/6):

Some cool flowers spotted during last weekend’s walks along the Torrente de Picapedreros and Finca La Soledad near Córdoba, Spain:

- Tuberaria guttata (Cistaceae)
- Sedum andegavense (Crassulaceae)
- Briza maxima (Poaceae)
- Cytinus hypocistis (Cytinaceae)

I would like to thank my colleagues @manumachadoeco.bsky.social, Wesley, Flavio, Edouard, Maria Antonia and the ICMBio for all their help whilst also taking care of their own activities. And I am grateful to the Cerrado for giving me the chance of experiencing magic moments such as this one:

The NEOFIRE team led by @ioliverasmenor.bsky.social has just returned from a 6-week functional traits campaign at Serra das Araras, Brazil! There, I measured photosynthetic and leaf traits of 102 Cerrado trees under different fire regimes @umramap.bsky.social @ecioxford.bsky.social @biology.ox.ac.uk

These could be outlined as:

A) fire as an ecosystem process to be introduced through rewilding

B) fire as a socioecological risk to be averted by rewilding

C) fire as a potential hazard brought by rewilding requiring management

D) fire as a beneficial management strategy put at risk by rewilding
March 9, 2025 at 7:42 PM
Understanding the role of fire in the context of rewilding is critical for effective scaling up of nature recovery. In this new paper, @chloestrevens.bsky.social, @ioliverasmenor.bsky.social and I review and synthesise the literature to find four main discourses:
