Summary:  View help for Summary This data publication includes tree height, diameter and performance data for Polyscias bisattenuata, a critically endangered Hawaiian tree species, as a part of an experimental planting study that tests how site variables and founder populations affect success. Seeds from 19 wild founders from three wild populations were selected to be genetically represented in translocation efforts. Seeds were germinated and propagated on the South Shore of Kauaʻi and 3,700 P. bisattenuata saplings were prepared for outplanting by late 2017. Saplings were approximately one year old and 20-40 centimeters (cm) in height upon planting across 11 translocation sites on Kauaʻi Island in Hawaiʻi. Selected translocation sites were both within and beyond the climate conditions represented by remnant populations. Survivorship, growth, and vigor of the translocated populations were monitored at two-years post-planting (2019) and four-years post-planting (2021 through early 2022). Additional data include understory measurements for each individual tree as well as soil, climate, and topographic data for each site.
