We generated a total of 2,313,977 16S archaeal raw reads across the 36 replicates (64,277 ± 23,335 SD per replicate). A total of 2,299,955 archaeal sequences (63,888 ± 23,473 SD per replicate) and 1,937 archaeal OTUs (54 ± 20 SD per replicate) remained for further analysis after quality filtering. The OTU data provide information on archaeal flux at an active restoration site at Mt Bold, a water catchment reserve of the Mt Lofty Ranges in South Australia, through a stagger of years and can be used accordingly.

Purpose
This project was conducted as a part of the author's PhD. The OTU data was generated for the manuscript titled "Archaeal community responses to a decade of ecological restoration" that uses eDNA assessment to provide a significant extension to current restoration monitoring practice.
Lineage
eDNA metabarcoding : Three 25 m x 25 m quadrats were randomly selected per site, giving a total of 24 quadrats across the 8 sites. Soil was sampled from the 0-10 cm and 20-30 cm soil horizons at each quadrat. A representative 50 g sample of soil was collected at each of these 24 quadrats by pooling nine soil samples from each soil depth, including soil from open areas and under plants. These nine soil samples were pooled into a sterile plastic bag, and homogenized using a sterilized trowel. All soil samples (n = 48) were frozen on site in sterile 50 mL falcon tubes until DNA extraction, hereafter referred to as technical replicates.
