 There are many, but one of the ones we are concerned about is maintaining the genetic resources of trees, which means they're genetic diversity. This is particularly important because of climate change, because trees that grow in different areas, even of the same species, may be adapted to wetter or drier conditions or cooler or hotter or different pests, and if we don't retain that diversity, the trees may lose their capacity to adapt. There's very little research on forest genetic resources. We know very little about the genetic diversity of trees. Maintenance of genetic diversity of trees is not part of forest management guidelines. So we don't know what we've lost and what we could gain by knowing about that and being able to harness it. So for example, choosing the right seed sources that will be adapted for future conditions or that will give us the best wood quality or the best fruit quality. We would like to see forest management guidelines include factors that relate to retaining forest genetic resources, which means guidelines for regeneration, for maintaining seed trees, for the distance between seed trees, for considering pollination and dispersal of seeds, making sure that protected areas also consider trees. Currently protected areas are established for many reasons, but none of those reasons is the protection of tree resources. So in both forest management and conservation, we'd like to see forest genetic resources considered and included. C4 is the lead center of the CGIR program on forest trees and agroforestry. Bioversity works in the context of that program. We collaborate closely with C4 researchers. We work together. For example, our project here in Cameroon, Gabel, and Congo DRC called Beyond Timber, which includes a component on understanding the genetic diversity of trees and how they're affected by logging, is carried out in collaboration with our colleagues here in Yaounde and C4. We have another project in collaboration with C4 in Burkina Faso, and we hope to work with C4 in many other places.
