The parallel_trees function assumes that all trees provided are roots of their respective forests. Within the code, the _arbor_index attribute is accessed, which only exists for trees that are forest roots. A fix for this needs to take care of cases where multiple trees from the same forest are given. If we are not careful, results could overwrite each other when recombined.
