A man-made nestbox put in to observe and mitigate impacts to hazel dormice (Muscardinus avellanarius) and two hazel dormice (inset) discovered throughout considered one 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 seek out and monitor hazel dormice, but additionally used to mitigate the lack of pure habitat attributable to elevated pressures from agriculture, forestry work and concrete enlargement. To maximise the probabilities for these synthetic nestboxes for use by hazel dormice, it’s essential that web site choice is rigorously thought-about. While habitat preferences for this species have been nicely documented, we recognized a lack of information surrounding microhabitat variables round occupied and non-occupied nestboxes and this grew to become the main focus of Joe’s Masters challenge on the College of Studying within the UK.
Our paper makes use of a machine studying method known as Random Forest regression to supply detailed perception into nest field choice by hazel dormice. We spotlight the advantages of this statistical method that may disentangle the results of many potential predictors even with comparatively small numbers of observations, and illustrate steps for good practise on its utility. The code used to analyse the info (within the R programming language) is obtainable 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 assist conservationists to position 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 will enhance inhabitants monitoring for this species and guarantee this stunning creature stays a part of our native fauna.

When animals are discovered throughout survey if potential intercourse and age are recorded, additionally noting any issues relating to situation (Photograph credit score Joe Malyan).
