The present study reviews the impact of mechanical interventions, and controlled burning combined with grazing in the Mediterranean-climate regions (MCRs) of the world. Relevant studies were searched for in the Web of Science database. Additional studies were located in the citations of these publications, and in a local database. Finally, 26 studies were included in this review. Since 1978, several other relevant studies have emerged at a rate of 24% in a 5-year time step. The studies have focused on the effects of combined grazing with other management tools on vegetation structure (18 publications), biomass productivity (16 publications), and floristic diversity (12 publications). The results were analyzed for (a) sites and treatments and (b) effects on plant structure, productivity and floristic diversity. Herbaceous forage increased after a reduction in shrub cover. Shrubs tended to recover in the grazed pastures. Vegetation height was reduced in almost in all cases according to available data. Despite its potential recovery, shrub biomass was affected by grazing in most cases. The impact of subsequent grazing was mixed regarding floristic diversity. Grazing is a useful tool for landscape management in MCRs, but the proper way to combine it with other interventions depends on the management goals.

Cattle grazing is particularly important to natural and semi-natural ecosystems, having often replaced grazing by smaller domestic ruminants such as goats and sheep. While cattle are mainly considered grazers rather than browsers, the pressures, direct or indirect, they exert on shrub encroachment are significant. Thus, their grazing and browsing activities can often be considered complementary to ecosystem management, especially in landscapes characterized by shrub presence and frequent wildfires. Several factors may influence the impact of cattle browsing, including the stocking rate, the specific breed of cattle, and their adaptation to the respective ecosystem, as well as the particular type of ecosystem. This review examines the impact of cattle browsing on shrubs across various temperate ecosystems. Findings indicate that cattle usually consume only 5–10% of woody forage, but exceptional browsers like Highland cattle can consume up to 45%, making them promising for controlling shrub encroachment. Nevertheless, grazing often negatively impacts shrub richness, especially when combined with management interventions or wildfires, thereby raising concerns about plant regeneration. Future research should prioritize the ecological value of indigenous browsing cattle breeds over productivity-focused goals; however, several studies fail to specify the breeds examined, thereby limiting the ability to draw breed-specific conclusions.
