WHAT THE EVIDENCE SAYS
A Peru Amazonas farm chronosequence compared silvopastoral stands aged one, four and seven years with a ten-year open pasture. Silvopastoral plots generally had higher richness and pasture production, with marked soil-property contrasts; organic matter and nutrients did not increase steadily with system age.
WHY IT MATTERS / OUR READ
Retained trees can help reconcile forage and heterogeneous vegetation; monitoring must also catch declining soil nutrients as grazing histories lengthen.
CAVEATS / UNCERTAINTY
Observational single-farm comparison with no direct tree-cover quantification, differing histories and sampling; not a replicated causal trial.
