The influence of fire frequency on the abundance of Maerua subcordata in the Serengeti National Park, Tanzania

Invasive woody shrubs, such as Maerua subcordata, pose significant threats to the Serengeti National Park's ecosystem by altering vegetation composition and providing little nutritional value while potentially being toxic to wildlife. Research reveals that increased fire frequency in the park correlates with higher abundance of M. subcordata, with burned transects showing significantly greater presence compared to unburned ones. The study, utilizing seven years of MODIS imagery (2000–2006), found a positive relationship between burn frequency and shrub abundance, while the number of years since the last fire had a negative effect on abundance. These findings highlight the ecological risks posed by invasive species in protected areas, emphasizing the need for further research to mitigate potential expansion and its consequences.
