This is an announcement for the paper "Finitely fibered Rosenthal compacta and trees" by Wieslaw Kubis. Abstract: We study some topological properties of trees with the interval topology. In particular, we characterize trees which admit a $2$-fibered compactification and we present two examples of trees whose one-point compactifications are Rosenthal compact with certain renorming properties of their spaces of continuous functions.
