Considering Soil Biota and Symbioses in Forest Management and Ecosystem Restoration

Abstract

At the 16th Biennial Conference of Science & Management on the Colorado Plateau & Southwest Region on 12–15 September 2022, the authors hosted a symposium on the topic of “Considering host-microbial interactions in ecosystem restoration”. The goal of this symposium was to showcase studies that demonstrate how soil biota and symbioses can be used to promote forest restoration. Two key principles emerging from the symposium and research on this topic include the following: (1) diverse, native mixes of appropriate soil biota can meaningfully shift forests and plantings towards more successful and ecologically appropriate conditions; (2) context is important to consider in determining the appropriateness of plant and microbial pairings, including the similarity of source material and work sites across a variety of factors. To summarize the literature and discussion on this topic, we offer a graphical depiction of several of the factors to consider.
