One of the aims of our work is to identify which species best support agroforest in the Amazon. There are well over 25 native Inga species in our study area. From our knowledge of these species elsewhere in South America we know that some are small-leaved or slow-growing species that would not be much use in soil rehabilitation whilst others do not respond well to pollarding. This leaves ten or so species that we would like to include in our experimental plots. The logistics of including additional species is, however, a challenge as trees produce fruit for a short period and when they do there is stiff competition for them from birds and monkeys. Also seed has to be planted within hours of being removed from the fruit. The result is that we are currently trialling only three Inga vareties: wild Inga edulis, domesticated Inga edulis and a species new to science. We lost out to monkeys over Inga ingoides fruit in March but were fortunate enough to collect fruit of Inga velutina (see image above) this April. Quick planting by Rolman and Rodrígo has ensured that we now have a batch of seedlings that should be ready for planting in a few months!
