A synthetic nestbox put in to observe and mitigate impacts to hazel dormice (Muscardinus avellanarius) and two hazel dormice (inset) discovered throughout one in every of our monitoring surveys (picture credit Clara Prieto and Joe Malyan).
Hazel dormice are one of many UK’s rarest mammal species, their inhabitants dwindling since 2000. Synthetic nestboxes are primarily used to search out and monitor hazel dormice, but additionally used to mitigate the lack of pure habitat brought on by elevated pressures from agriculture, forestry work and concrete growth. To maximise the possibilities for these synthetic nestboxes for use by hazel dormice, it’s essential that website choice is fastidiously thought of. While habitat preferences for this species have been effectively documented, we recognized a lack of awareness surrounding microhabitat variables round occupied and non-occupied nestboxes and this turned the main focus of Joe’s Masters challenge on the College of Studying within the UK.
Our paper makes use of a machine studying strategy known as Random Forest regression to supply detailed perception into nest field choice by hazel dormice. We spotlight the advantages of this statistical strategy that may disentangle the results of many potential predictors even with comparatively small numbers of observations, and illustrate steps for good practise on its software. The code used to analyse the info (within the R programming language) is offered on-line, and we hope could also be helpful to these wanting to use Random Forest modelling.

Understanding microhabitat options that would have an effect on nestbox occupancy can help conservationists to put and handle nestbox websites. If extra dormice use and profit from supplied synthetic nestboxes, particularly in habitats the place discovering pure nests is low, we can enhance inhabitants monitoring for this species and guarantee this stunning creature stays a part of our native fauna.
