“…All three study sites were located in the Kwakuchinja wildlife corridor between Lake Manyara National Parks and Tarangire National Parks in Northern central Tanzania (Figure 1). This corridor is part of Kwakuchinja Open Area which covers about 600 km 2 , bounded by parallels 03 35 0 38 00 and 03 48 0 02 00 S and meridians 35,048 0 21 00 and 35 59 0 25 00 E (Martin et al, 2019) and forms part of the Tarangire -Manyara ecosystem (TME) which has high mammal species diversity (Pittiglio et al, 2012). The corridor was classified as 'critical' by Caro et al (2009) who noted that the high density of human settlements and expansion of croplands were threats affecting the corridors future existence.…”

“…In accordance with the Act, human settlement and the grazing of livestock are unrestricted, and hunting of wildlife is only permitted under licence (Weldemichel, 2020). Twenty-five large mammal species have been recorded within GCA (Martin et al, 2019) including high abundance of game species including zebra (Hippotigris quagga), Grants gazelle (Nanger granti), impala, (Aepyceros melampus) , Hartebeest (Alcelaphus buselaphus) and Buffalo (Syncerus caffer). These mammals provide rich and varied dung resources that are expected within savannah regions and required for supporting robust and diverse dung beetle assemblages.…”

Habitat loss and degradation are the most widely cited drivers of changes in species abundance and diversity. We explored changes in dung beetle species diversity and composition across different land uses in the north west Tanzanian savannah. We expected a negative response gradient in the diversity and composition of the dung beetle community, from land uses that preserve vegetation and hold native mammal diversity to livestock intensive and heavily grazed areas. Dung beetles were sampled in a protected area and two anthropogenically influenced land use types. Species richness and composition of each land use type, including differences in diversity and functional groups were analyzed and indicator species for each land use gradient were identified. As expected, diversity and community composition varied between areas with less environmental change compared to those impacted anthropogenically. We conclude that conservation of protected areas within African savannahs can provide a functionally rich dung beetle community and subsequently rich ecological functions. The dung beetle species identified by this study as eco-indicators can be used as a benchmark for future studies that use rapid monitoring to assess disturbance in African savannas.

“…It is undoubtedly in the realm of policy and socioeconomics where some of the greatest challenges to securing wildlife movements along the drought corridor lie. If these are not addressed we will simply monitor and map land use land cover changes in the wildlife corridors with unprecedented accuracy (for example, Mucova et al, 2017;Martin et al, 2019), together with the wildlife declines that will inevitably follow.…”

Take me to the River along the African drought corridor: Adapting to climate change

This paper brings together a wide range of concepts from climate change predictions, palaeoecology, wildlife ecology and sustainable livelihoods in order to prioritise adaptive management measures that are necessary for the conservation of the African megafauna. Climate change predictions emphasise the severe aridity that will surge into southern Africa later this century and must be contrasted with the relatively wetter conditions in eastern Africa. The evolution of African mammals and their adaptive responses to past episodes of climate change is explained by reference to range shifts and movements along Balinsky’s (1962) ‘drought corridor’ that extends from SW Africa northeastwards to Somalia and then westwards across the Saharan-Sahelian zone. The drought corridor today could potentially extend from Kenya southwestward through to Botswana/South Africa and Namibia, via connectivity corridors linking existing wildlife areas, forming the Kalahari-Rift Valley Transfrontier Conservation Landscape (KALARIVA TFCL). The most promising route along the drought corridor links the Chobe – Linyanti – Kwando river systems of Botswana/Namibia with Luangwa Valley in Northern Zambia, along the Zambezi River via Lake Kariba (Matsudonna and Mana Pools) in Zimbabwe. Malawi poses an absolute barrier to such connectivity and by the turn of this Century runs the risk of confining the area to the south almost entirely to the SW arid adapted fauna and that to the north to water dependent ungulates such as elephants, buffalo and zebra. The key movement corridors are identified in a bid to extend the spatial and temporal scale of conservation planning in order to adapt effectively to climate change. The importance of ‘co-existence’ between wildlife and people is emphasised together with the need for local communities to benefit from sharing the KALARIVA TFCL with African wildlife, via new models of conservation financing and management that reward rural African communities for being the true custodians of the African megafauna.

“…The challenge is to identify management opportunities that preserve ecological functions while minimizing human land-use constraints (DeFries et al 2007). Land cover changes in Europe's protected areas are a frequent research object studied mainly using GIS technologies (e.g., Gabrovec et al 2013;Zafar 2014;Martinez del Castillo et al 2015;Janík and Romportl 2018;Hamad, Kolo and Balzter 2018;Krajewski 2019;Martin et al 2019;Rodríguez-Rodríguez, Martínez-Vega and Echavarría 2019;Ribeiro and Šmid Hribar 2019).…”

As a country with abundant natural resources, Slovakia has legislation to protect significant parts of nature and landscape. The paper aimed to identify the extent and nature of land cover changes in large protected areas in Slovakia and to determine how had these changes impacted the diversity and ecological stability of the landscape. We used the CORINE Land Cover data from 1990 and 2018 to identify landscape changes and analyzed them spatially and statistically. Overall, 21.7% of the total area was changed. In terms of landscape changes, nine dominant sub-processes within five »land cover flows« were identified. In terms of changes in landscape diversity and stability the most significant changes occurred in the NP Nízke Tatry.
