The Tree Improvement Program Cooperative is located on the North Carolina State University campus in Raleigh, NC, the mission of the Cooperative is to economically increase forest productivity through the genetic manipulation of loblolly pine populations.
The cooperative is working with temperate pines. However this is a good model to follow if we want to do tree improvement in our tropical trees. Nicaragua has 4 pine species. Several Nicaraguan natural populations or provenances are very important. This has been proved in several international genetic tests conducted by the Oxford Forestry Institute (OFI - http://www.plants.ox.ac.uk/ofi/) and the Tree Improvement and Conservation Cooperative (Camcore - http://www.camcore.org/), where Nicaraguan pines gave outstanding values of DBH, growing, and wood quality.
