Widespread deforestation has impacted biodiversity patterns globally, but the potential for forest plantations to restore remains unclear. Here we used environmental DNA (eDNA) analysis compare freshwater insect assemblages between native and exotic forests in New Zealand, a region that experienced heavy over recent centuries. Our of mayfly, stonefly, caddisfly (Ephemeroptera, Plecoptera, Trichoptera [EPT]) eDNA from 15 plantation streams southern Zealand yielded 85 taxa, most which were shared across these habitat types. Assemblages structured primarily by rather than type. Although taxonomic diversity EPT was lower relative forest, highly similar those streams. These findings suggest can broadly previously deforested aquatic communities resemble forest.

ABSTRACT Understanding the geographic distributions of rare species can be crucial for conservation management. New environmental DNA (eDNA) technologies offer potential to efficiently document endangered species, but date, such screening has focused largely on vertebrate taxa. Here we use freshwater eDNA assess distribution Maungatua stonefly, Zelandoperla maungatuaensis , a flightless insect previously known from only handful streams draining 4‐km section mountain range in southern Zealand. We analyzed 12 stream localities across range. Screening with commercial COI primers failed detect focal Z. . However, newly designed species‐specific detected this taxon four adjacent east‐flowing contain and two which it had not been detected. Subsequent manual surveys confirmed presence discovered populations, barcoding revealing that they together represent unknown, genetically divergent subclade. Our results illustrate metabarcoding help delineate ranges taxa, highlight importance primer specificity when These findings also have considerable implications companies offering biodiversity health services targeting invertebrates.
