Twelve Mile Spring

FOMS Fixes Faulty Fencing

In the early 1980s, the State Environment agency commissioned studies to document the features and importance of mound springs in South Australia. Eleven springs were identified as being of particular significance and were fenced by the Department in the period 1984 to 1988. These springs were Blanche Cup, the Bubbler, Coward Spring (all now within Wabma Kadarbu Mound Springs Conservation Park), Strangways Spring (on Anna Creek), Tarlton, Outside, Twelve Mile, Fountain and Big Perry springs (all on the Peake Pastoral Lease), Nilpinna Spring on Nilpinna Pastoral Lease and Big Cadna-Owie Spring on Allandale Pastoral Lease. The Department monitored the condition of these fenced springs from 1984 to 2005. With the exception of occasional fence repairs by Peake station personnel at Twelve Mile and some work to strengthen weak points and install bayonet gates in the early 1990s, the fencing has not been actively maintained.  It has lasted well, but is now at a stage where attention is needed.

Maintenance and repair work on the fencing around those springs outside of Wabma Kadarbu Mound Springs Conservation Park was one of the main tasks for FOMS volunteers in their trip to the springs in late July 2016. The fenced spring at Strangways did not require attention as this is within the much larger area at Strangways fenced by S Kidman and Co in the mid-1990s. The fencing group in the July 2016 trip comprised Brenton Arnold and Brendan Lay, with support from Bruce Gotch, Bernice Cohen, Colin Harris, Simon Lewis, Elizabeth Lay, Claire Bockner and Arabana elder Dean Stuart. Brenton, still in recovery from a bout of the ‘flu, brought with him a trailer load of fencing materials from Port Augusta.

The most arduous fencing work was at Twelve Mile Spring, where there have been problems in the past with cattle breaching a weak section of fence and gaining access to the springs. There, a section of fence needed to be realigned to avoid the vulnerable section.

Significant fence work was also needed at the Fountain. Here the spring tail passes through the fence and the fence has become weakened as a result of cattle pugging and eroding the wetland area just outside the fence. Brenton and Bren reinforced this section with star-droppers and additional wiring. At nearby Outside Spring one section of fence needed re-straining.

After completing the fencing work on the Peake, the group moved on to Nilpinna Spring, on Nilpinna Station. It was expected that significant repair work might be needed here as the spring area had been burnt three to four years ago – in an attempt to control bamboo growing at the spring – and this burn had damaged part of the fence. However, the singed fence-posts were in reasonable condition, so the task was not quite as great as anticipated. Vegetation was cleared away from the damaged section, the fence was re-strained and a number of spacers replaced.

Dean Stuart and Bruce Gotch check the bayonet gate at Twelve Mile Spring

Bayonet gates at each of the above springs were also serviced, with Bruce Gotch taking charge of this work. The bayonet gates were installed in the early 1990s after a particular problem with cattle gaining access through the fence to the Fountain. The design of the bayonet gates is such that cattle cannot get through them from outside but can get through them from inside the fenced area: thus if cattle do gain access through the fence in some way, they do have an opportunity to exit the fenced area via the bayonet gate.

While the above work may secure the fenced springs for the next few years, FOMS is concerned that ongoing reliance on volunteers to maintain the fencing is not necessarily the best option. FOMS will be promoting discussions aimed at looking at other partnership approaches that may provide better security for these areas into the longer term.
