“…The core forests include three different types (1) Core 1: forest patches area < 250 acres (1.012 km 2 ), (2) Core 2: medium core (forest patches area between 250 and 500 acres (1.01–2.2 km 2 ), and Core 3: large core (forest patches area > 500 acres (> 2.2 km 2 ) 91 . The peripheral forest was further classified into perforated (1) inner edge: forest pixels on the edge of small interior non-forest, and (2) edge forest or outer edge: pixels that are between forest and large non-forest areas 105 .…”

Forest cover is the primary determinant of elephant distribution, thus, understanding forest loss and fragmentation is crucial for elephant conservation. We assessed deforestation and patterns of forest fragmentation between 1930 and 2020 in Chure Terai Madhesh Lanscape (CTML) which covers the entire elephant range in Nepal. Forest cover maps and fragmentation matrices were generated using multi-source data (Topographic maps and Landsat satellite images of 1930, 1975, 2000, and 2020) and spatiotemporal change was quantified. At present, 19,069 km2 forest cover in CTML is available as the elephant habitat in Nepal. Overall, 21.5% of elephant habitat was lost between 1930 and 2020, with a larger (12.3%) forest cover loss between 1930 and 1975. Area of the large forests (Core 3) has decreased by 43.08% whereas smaller patches (Core 2, Core 1, edge and patch forests) has increased multifold between 1930 and 2020. The continued habitat loss and fragmentation probably fragmented elephant populations during the last century and made them insular with long-term ramifications for elephant conservation and human-elephant conflict. Given the substantial loss in forest cover and high levels of fragmentation, improving the resilience of elephant populations in Nepal would urgently require habitat and corridor restoration to enable the movement of elephants.

“…Natural and human‐ignited fires have a defining impact on Earth’s ecosystems. Fires are a major source of global greenhouse gases and aerosols (Maraseni et al., 2016; Van Der Werf et al., 2010), and modify nutrient and water fluxes that shape ecosystem productivity (Beringer et al., 2004; Frost & Robertson, 1987). They moreover alter vegetation biomass and structure (Van Langevelde et al., 2003), transforming ecological communities through direct killing, and through their impacts on growth and reproduction rates as well as on species interactions (Frost & Robertson, 1987).…”

Fires play an important role in savannah ecosystems, shaping among other things vegetation structure and altering species composition. As direct and indirect anthropogenic pressures on these ecosystems increase, fire dynamics in savannahs are expected to change in the coming decades, with potential impacts on ecosystem functioning. Although the ecological impacts of fires are relatively well-known, the factors that shape fire dynamics in these ecosystems have received less research attention. Using Pendjari National Park (Benin) as a case study, we assessed the importance of different biotic and abiotic factors in shaping fire size and spread in the region. Our results show that fires spread faster (1) in the middle of the dry season compared to the early or late dry season, (2) in areas that are far away from natural and anthropogenic firebreaks, and (3) in areas that are covered with highly flammable vegetation. By contrast, most vegetation types had little influence on fire size, which seems to depend instead on rainfall. Our approach and results highlight new avenues for satellite data to improve our understanding of fire dynamics in large, remote savannah ecosystems and to improve our ability to predict how fires spread, a key variable for wildlife management in the face of rapidly changing environmental conditions.

“…Today, there are now over 70 registered savanna burning projects in northern Australia (Commonwealth of Australia 2018a). These registered savanna burning projects cover a broad range of land tenures, and all utilise the methods developed in western Arnhem Land to produce carbon credits (Maraseni et al 2016; Commonwealth of Australia 2017). Currently accounting for 10% of Australian carbon credit issuance, the savanna burning projects constitute a sizeable reduction in Australia's carbon emissions (Commonwealth of Australia 2018a).…”

The growth of the carbon industry in Australia over the last decade has seen an increase in the number of eligible offsets projects utilising the savanna burning methods in northern Australia. Many of these projects are operated by Aboriginal people on Aboriginal lands utilising local Aboriginal knowledge and customary burning practice. The present paper reviews existing land management planning documents to describe the aspirations of Traditional Owners in relation to fire management at a regional scale in Arnhem Land. Available data collected in the course of savanna burning operations are then utilised to examine the extent to which the savanna burning projects are meeting these goals. There were six clear goals in relation to fire management within the planning documents across Arnhem Land. Traditional Owners want to: (1) continue the healthy fire management of their country; (2) see fewer wildfires; (3) protect biodiversity; (4) protect culturally important sites; (5) maintain and transfer knowledge; and (6) create a carbon abatement. The results from this paper suggest that although the savanna burning projects are annually variable, these goals are being met. Importantly, the present paper clearly communicates a description of contemporary fire management from the perspective of Traditional Owners at a broad regional scale.
