02 9385 2111 david.keith@unsw.edu.au The Upland Heath Swamps Plot Network Soil Properties Data Package contains detailed soil analysis from 60 established swamp monitoring sites in upland swamps scattered throughout the study area (Keith and Myerscough 1993). Each site is sampled in nine combinations of moisture-by-vegetation structure strata. The Upland Heath Swamps Plot Network research plots commenced in 1983 and have been revisited in 2004, 2009 and again in 2014. A synopsis of related data packages which have been collected as part of the Upland Heath Swamps Plot Network’s full program is provided at http://www.ltern.org.au/index.php/ltern-plot-networks/upland-heath-swamps.

Sampling of soil is stratified along the soil moisture gradient and across the range of structural variability in the vegetation. Thus three categories of soil moisture and three categories of vegetation structure (based on the height and form of shrubs) are sampled in a factorial design at 60 sites in upland swamps scattered throughout the study area (Keith and Myerscough 1993). Each permanent swamp monitoring site consists of a belt transect of 30 contiguous 0.5x0.5 metre quadrats. Quadrats 1 and 30 are marked with steel star pickets, extending approximately 1. 5 m above ground surface, and located on the Map Grid of Australia (Geodectic Datum of Australia) using a global positioning system.

Duplicate samples of surface soils (0-7 cm depth) are collected from a stratified random subsample of transects from the nine combinations of the moisture-by-vegetation structure strata using an auger 2.5 cm in diameter. All samples were collected on the same day, homogenised and stored in sealed clip-lock plastic bags for transport to the laboratory for analysis of exchangeable cations (K, Na, Mg, Ca, Al), pH, electrical conductivity (EC), water content, loss on ignition (LOI), total phosphorus (P), total iron (Fe) and nitrate (NO3). Cation exchange capacity was determined by the Silver Thiourea method, pH was determined using 1:2 CaCl2 extract, electrical conductivity and nitrate are determined in 1:5 water solution, total P and Fe are determined using HCl digests, LOI is gravimetrically determined at 55C and water content is determined by moisture lost on drying the sample (Keith and Myerscough 1993).

•2.5 cm pipe auger •plastic bags •soil analytical laboratory During 2014, soils were sampled at all 54 sites. In previous surveys (only year recorded, not date), they were sampled at a random sample of 20 sites stratified by the soil moistire gradient and vegetation structure. Additionally, the exchangable manganese (Mn), total organic carbon (TOC) and moisture content were not measured in the years before 2014. The next census is scheduled for 2019 or within 12 months of the next bushfire, whichever occured first. Surface litter was removed from samples prior to collection. Originally each sample site was a belt transect of 60 contiguous 0.5x0.5 m quadrats, in which presence/absence of all vascular plant taxa were recorded (based on whether they were overhanging the quadrats) and tallied to give a frequency out of 60. The sites were originally sampled in 1983, marked in the field by two wooden stakes at either end of the transect, and plotted on a 1:10 000 aerial photograph. By 2004, it was possible to relocate 54 of the 60 original transects and of these, at least one of the original markers was found for 20 transects. During the intervening years, some of the wooden markers had been consumed by fires, but based on the annotated aerial photograph, field notes and detailed recollections of the original observer (David Keith), transects were confidently reestablished within approximately 10 m of their original location. These formed the basis for establishing permanent swamp monitoring sites, which are now marked in the field at the positions of quadrats 1 and 30 with steel star pickets, extending approximately 1.5 m above ground surface, and located on the Map Grid of Australia (Geodectic Datum of Australia) using a global positioning system. 1408532875740 Data Owner 1416448970563 Plot Network Contact 1416440473965 Plot Network Contact 1416440539634 Plot Network Contact 1416440643143 Plot Network Contact 1416440710772 Plot Network Contact Since 2012 this project has been part of the Long Term Ecological Research Network (LTERN).
