1.2 Objectives
In this review, we discuss the current incorporation of invertebrates
and microbes into rewilding and restoration projects and how their use
can be improved in the future. First, we explore how invertebrates and
microbes have been used in ecosystem restoration to date and provide a
summary table that highlights significant knowledge gaps in our approach
to invertebrate and microbial rewilding so far. Next, as rewilding has
significant ecosystem ramifications (both intentional and
unintentional), we discuss scenarios in which invertebrate and microbial
rewilding is justified during restoration. Finally, we discuss how
invertebrate and microbial rewilding can move forward in the future by
utilising their unique characteristics. This includes specific examples
of empirical invertebrate and microbial rewilding projects that land
managers can use during restoration to improve the recovery of ecosystem
functions and biodiversity. Our goal is to challenge the current
plant-focussed view of restoration and provide the foundations for a
more holistic approach that better values the role of invertebrates and
microbes during ecosystem recovery.
