Conservation benefits of managing island pests - Lachlan Francis

18 February 2019

Lachlan evaluated the consequences of cat management on Bruny Island, Tasmania. Expert opinions informed population models to understand how native species (plovers, shearwaters, pardalote, penguins and quolls) would be impacted by cat control. Field research showed that cat management would not change the rat population on the island. The eradication of cats poses a complex, high risk and expensive option in the Bruny Island context. In the context of investment to return, there are other islands where cat control benefits are similar but the risk and costs are expected to be lower. Lachlan also shared his experience working on Macquarie Island.

Lauren Johnson: Continuing the recovery of the Barred Galaxias - Learning by doing

26 October 2018
The Barred Galaxias Galaxias fuscus, is a small, non-migratory fish species with a limited distribution, and threatened in Victoria and nationally. Its main threats are predation by trout, drought, and loss through fires and isolation. Conservation actions have been implemented for 22 years including annual population monitoring, installing instream barriers for protection from predation, trout removal, fish translocations, captive maintenance after the 2009 fires, and a breeding program. Recent work assessed the effectiveness of the trout control strategy including factors that influence trout incursions and options for improvement.  This found there was a difference in the effectiveness of barrier types in keeping out trout; natural barriers were the most effective, and logs and weirs were able to keep trout out but not completely.  Distance from towns was found to be an important factor, with the likelihood of trout being present above a barrier reducing with each km from a town. The current trout control method was found to be effective, with regular surveys and early trout removal after detection important. Many of the learnings from this long-term conservation effort can be transferred to management of other threatened galaxiid species. Contact Lauren Johnson for more information.

Brad Farmilio: Quantifying effectiveness of weed control in threatened Victorian grasslands

26 October 2018

Native grasslands have long been important ecologically (high flora diversity on a small-scale, and habitat for fauna) and culturally (providing food sources such as starch via tubers and protein via game e.g. kangaroos). Our grasslands have suffered a substantial decline, with <2% remaining in Vic. They are susceptible to weeds, which out- compete native plants, change fauna habitat and alter disturbance regimes. Weed management options are diverse and include herbicides, scalping, selective grazing, fire, hand pulling, vinegar and biological controls.  Surprisingly, the impact and effectiveness of most weed control actions aren't monitored, with area treated often the only type of reporting. This project determined how effective the commonly applied approach of weed control (using herbicides) was for grassland restoration. Flora surveys were conducted and annual spot spraying of herbicide (Glyphosate) targeted exotic perennial grasses. Monitoring began in 2014, with 40  sites (roadsides and rail reserves) surveyed, and then combinations of treated and untreated (control) sites monitored in subsequent years. There were reductions in weed cover when sites were treated with herbicides, however weeds were very difficult to eliminate and once treatment ceased, weed cover increased. In terms of native species richness, treated sites did not accumulate native species like the untreated sites, indicating the effects of three years of herbicides can reduce native plant richness. Brad emphasised the importance of having control sites to assist in interpretation of results, and highlighted how this work was one of the first to monitor the effectiveness of weed control in native grasslands. The results indicate that annual herbicide application should not be considered a universal remedy, and that there may be negative impacts associated with herbicide accumulation on native species richness. Annual spot spraying can reduce the threat of weeds, but asset response is delicate, and further investigation is required on how to eliminate weeds. Contact Brad Farmilo  for more information.

Jason Alexander: Talking to Deakin's ghost about water governance

26 October 2018

There have been significant changes in water resource policy and management since the time of Alfred Deakin. Deakin believed that the state needed to own and control water resources and limit vested interest influence in water management. Today, the once State-owned resource is largely effectively privatised through tradeable water rights. With average rainfall not truly reflecting a system where extremes of wet and dry are common, the social, political and environmental challenges in allocating water add to the management complexity. Historically, water policy reforms have followed drought events and are deeply divisive as they alter power relations and change access to resources. As we transit from a past of economic-centric water policy (focused on irrigation) to hydro-sustainability (which considers social and environmental water values), Jason emphasised the importance of engaging with the community, adaptive governance to manage climate change risks and strong reform foundations to ensure the responsibilities of agencies involved in water management are clear. Contact Jason Alexander for more information.
