This link contains the R script used to undertake the analyses in the published manuscript "Not all cover is equal: a multi-material comparison of artificial cover boards for small vertebrate surveys in subtropical Queensland, Australia".

Surveys yielded 1,137 vertebrate detections (950 reptiles, 108 mammals, 79 amphibians). Mean reptile detection was highest under timber (β = 3.54, 95% BCI 2.91–4.20); however, corrugated tin and carpet also exceeded detections over roofing tiles. Tin yielded the highest detection rates for mammals and amphibians, but ACBs overall were less useful for these taxa.

Seasonal variation markedly influenced effectiveness: carpet outperformed other materials during winter, whereas tin and timber were optimal in summer for reptiles, corresponding with temperature changes under the cover boards. Species-specific analyses highlighted some clear material preferences; notably, the threatened <i>Delma torquata,</i> where detection was 6.3 times higher under carpet compared to roofing tiles.

Our results suggest ACBs are an effective tool for surveying reptile communities within subtropical environments. We recommend using a combination of timber, tin, and carpet to maximise reptile detection probabilities, emphasising seasonal variation and deployment duration as critical considerations. Future research should explicitly compare ACBs with traditional methods including active searching to assess trapping efficiency, and use of more environmentally friendly cover boards such as coir.</p>
