生態學家計劃於澳洲新南威爾斯州的一個森林，收集長腳長鼻袋鼠捕食者的糞便，並嘗試從中找出其DNA。長腳長鼻袋鼠於該區最後一次記錄已是1990 年代初期。計劃希望收集1000個貓、狐狸、澳洲野犬或袋鼬的糞便樣本；研究結果將有助長腳長鼻袋鼠的復育計劃。

In the South East Forests in Australia, ecologists plan to search for the vulnerable long-footed potoroo’s DNA in their predators’ feces. the long-footed potoroo was last recorded in this area in the early 1990s. The search aims to collect 1000 samples feces of cats, foxes, dingoes and quolls; the result will help to plan for the rewilding project of these potoroo.
