As global carbon emissions continue to rise, effective strategies for enhancing forest productivity and accelerating carbon sequestration are crucial. Plant growth-promoting rhizobacteria (PGPR) are one of the biological approaches that stimulate plant growth, improve nutrient uptake, enhance disease resistance, and promote soil health, offering an eco-friendly and sustainable measure to boost forest establishment and development. Studies have demonstrated that PGPR may increase root biomass, facilitate efficient nutrient cycling, and promote plant stress tolerance, thereby contributing to enhanced carbon fixation in forest ecosystems. Additionally, the symbiotic relationships between PGPRs and tree species improve soil carbon storage by influencing microbial communities and soil organic matter dynamics. This chapter examines the role of PGPRs in enhancing the growth and carbon sequestration capacity of forestry species, highlighting the need for further research into their application in forest management practices. Moreover, this chapter inferred that utilising PGPRs could provide an innovative and cost-effective solution for enhancing the carbon sequestration potential of forests, contributing to climate change mitigation efforts.
