The city's lungs.
Kisumu is Kenya's third largest city, and Old Bonjoge is the only woodland near it. 2,150 hectares, most of it cleared as the population grew. It also drains into Lake Victoria, a basin 45 million people depend on (World Bank, 2025) and one holding over 651 freshwater species (IUCN, 2018). Restoration runs through nurseries raising native seedlings, planted across two windows a year on the long and short rains. Survival is tracked through Veritree's platform, currently estimated at 75%.
