Choose up to four. The comparisons that teach you something are between organizations of similar size doing similar work, so put a city nonprofit beside another city nonprofit rather than beside a national program.
One Acre Fund counts tree seedlings that farmers received and planted, not surviving trees; its 2025 report says it 'conservatively expects about half of these trees to survive to maturity'. The cumulative total of 250 million is counted from 2019 only, while the older impact page still says '100 million trees to date'. Adding the 134 million planted in 2025 to the 250 million reached by end-2024 gives roughly 384 million since 2019, a figure the organization has not itself published.
