The Desert Jewels project conducted by the Department of Environment, Water and Natural Resources (DEWNR) covers many aspects of mound springs management, some of which are described in other items in this newsletter. One particular area of interest is the effect of controlled or pulse grazing on mound springs. Following consultation between DEWNR and FOMS personnel and Colin Greenfield at Billa Kalina Station, a spring is to be fenced on Billa Kalina in a configuration that will allow controlled grazing in part of the fenced area and complete exclusion of stock in another section. Another part of the spring wetland will be permanently open to grazing so, in effect, there will be three management regimes to monitor at the spring.
During FOMS’ trip to the mound springs in July 2016. Brendan and Elizabeth Lay and Bernice Cohen visited Billa Kalina. They met with Colin Greenfield to discuss arrangements for the fencing, then drove on to the spring to be fenced to check the alignment for the fencing and to collect baseline vegetation data. The data will provide a useful comparison for future measurements when the fencing is in place.
Ongoing consultation with Colin Greenfield will be needed to keep records of grazing patterns around the spring and within the exclosure which will be stocked from time to time.
As can be seen from the photo, the spring has a fairly uniform coverage of low sedges, in this case the bore-drain sedge Cyperus laevigatus. There are currently no reeds, Phragmites, at the site.
