Datasets consist of monitoring data on seedling survival and growth, both prior to (i.e., in the nursery) and after outplanting, collected between 2009 and 2016 from the tropical peatland of the Natural Laboratory of Peat-swamp Forest special research zone in Sebangau National Park, Central Kalimantan, Indonesia. The data include four data files, which provide processed summary data on survival and growth of seedling cohorts, plus the data on individual seedling survival and growth from which these summaries were derived, for both seedlings being raised in the nursery and following outplanting. Nursery data include monitoring datasets relating to seedlings acquired both from seeds and as wildlings, and for fertilised vs. unfertilised seedlings. Outplanting data include monitoring datasets from different treatments, including in previously burned vs. unburned areas, with and without fertiliser, and using conventional plastic polybags vs. organic baskets for planting.
