 Being abundant throughout its significant range , the noisy miner is considered of least concern for conservation , and its extreme population densities in some areas actually constitute a threat to other species . The strong correlation between the presence of noisy miners and the absence of avian diversity has been well documented . The role played by the noisy miner in the steep decline of many woodland birds , its impact on endangered species with similar foraging requirements , and the level of leaf damage leading to die @-@ back that accompanies the exclusion of insectivorous birds from remnant woodlands , means that any strategy to restore avian diversity will need to take account of the management of noisy miner populations . Some habitat restoration and <unk> projects have inadvertently increased the problem of the noisy miner by establishing the open eucalypt habit that they prefer . A focus of many regeneration projects has been the establishing of habitat corridors that connect patches of remnant forest , and the use of eucalypts as fast @-@ growing nurse species . Both practices have sound ecological value , but allow the noisy miner to <unk> , so conservation efforts are being modified by planting a shrubby understory with the eucalypts , and avoiding the creation of narrow <unk> , corners or clumps of trees in vegetation corridors . A field study conducted in the Southern Highlands found that noisy miners tended to avoid areas dominated by <unk> , species of which in the study area had <unk> leaves . Hence the authors proposed <unk> projects include at least 15 % <unk> species with <unk> leaves if possible , as well as shrubby understory plants .
