Effects of restoration practices on biodiversity in temperate and boreal forests.

Native Plants
The mosaic of dead logs, open patches, and scorched ground that forest managers create mirrors the same structural variety that makes old-growth woodlands refuges for rare mosses, beetles, and woodland wildflowers you might spot on a nature walk.
Scientists looked at dozens of studies on how forest managers can help nature recover after heavy logging. They found that techniques like controlled burns, selective tree removal, and leaving dead wood on the ground do help plants and flying insects bounce back — but birds can struggle when too many trees or shrubs are removed, and mosses and lichens can be harmed by fire. The big takeaway is that forests need a mix of different approaches, not one-size-fits-all treatment.
Key Findings
Across 93 studies, restoration practices had an overall positive effect on species richness and abundance, with the strongest benefits seen for plants and flying invertebrates.
Thinning and understory removal negatively affected birds, while prescribed burning had negative effects on bryophytes (mosses) and lichens.
83% of data points came from within 10 years of restoration start, leaving long-term (decade+) outcomes largely unstudied.

A large review of 93 forest studies found that restoration practices like controlled burning, thinning, and adding dead wood generally boost biodiversity, but no single method helps all wildlife equally — and the long-term effects beyond 10 years remain largely unknown.
