than 24 average native CPUE was 6.2. In sites with water depth lower than 0.91m average CPUE was 2.3 and those between 0.91m and 0.26m had average CPUE of 5.9. Figure 59 Classification and Regression Tree of native fish CPUE abundance Exotic fish The proportion of the wetland inundated had a significant effect on the abundance of exotic species, with exotic fish species more abundant in wetlands that were only partially inundated (less than 0.8) (Figure Of these wetlands with higher exotic fish 60). CPUE, deeper wetlands had higher CPUE than did wetlands less than 0.24m, broadly reflecting the response of all fish species to wetland inundation. Figure 60 Classification and Regression Tree of exotic fish CPUE abundance Frogs and tadpoles Overall, 2,212 adult frogs (seen and heard) and 1,100 tadpoles of six species were recorded between September 2014 and May 2015 across 10 LTIM monitoring sites, with two sites remaining dry throughout 2014-15. Adult barking marsh frogs (Limnodynastes fletcheri), spotted marsh frogs (Limnodynastes tasmaniensis), plains froglets (Crinia parinsignifera) were recorded in all three zones. Peron’s tree frogs (Litoria peronii), inland banjo frogs (Limnodynastes interioris) were less widespread, while the vulnerable southern bell frog (Litoria raniformis) had the most restricted distribution, only occurring across the four Nimmie-Caira sites. Commonwealth environmental watering targeted known habitats of the southern bell frog (Litoria raniformis) in the Nimmie-Caira zone (Action 6). Calling and tadpoles of southern bell frogs and other frog species were recorded at all four LTIM monitoring wetlands in the Nimmie-Caira, indicating that these flows were successful
