“…The practice of producing crops in monoculture systems may be related to the proliferation of specific pest species and decline in the presence of natural predators. This scenario happens when these systems produce an ideal habitat for pest propagation while simultaneously reducing the ability of the same landscapes to sustain populations of natural predators (Altieri & Nicholls, 2002; Egonyu et al., 2022; Nobilly et al., 2023). The destructive impact of herbivorous insect pests on oil palm productivity and yield has been substantiated by both previous empirical studies and reviews (e.g.…”

One of the key ecosystem services offered by avian biodiversity within agricultural landscapes is natural predation. Nonetheless, the current use of biological control agents such as farmland birds in oil palm plantations is relatively limited. This study aimed to assess the potential roles of avian biodiversity, particularly insectivores that provide natural predation against oil palm herbivorous insects. We also investigated the influence of local‐ and landscape‐scale variables on foliage damage (crown or frond). Our data showed that crown damage decreased with increasing farmland bird richness (overall and insectivore), shrub cover, dried biomass and elevation, but increased with epiphyte cover, oil palm height and distance to continuous forest. Frond damage was negatively related to bird richness (overall, insectivore and non‐insectivore) and non‐insectivore abundance, elevation and shrub cover, while increased with insectivorous abundance, epiphyte cover, oil palm height and distance to continuous forest. We also found that plantations (≥50 ha) were more susceptible to foliage damage from pest insects than smallholdings (<50 ha). There was no evidence that indicate the influence of forest patches on foliage damage. Synthesis and applications. Our study highlights the economic value of conserving biodiversity, most notably, farmland birds and continuous forests with respect to biological control of defoliating pests and maintaining yield productivity in oil palm cultivation. Growers, particularly major plantation companies should make oil palm farming more biodiversity‐friendly in order to increase the number of biological control agents such as birds.

Eucalypt monoculture plantations can adversely impact soil properties. However, a thorough assessment of their effects on soil invertebrate communities is lacking, impeding our ability to acquire a deeper understanding about the potential impacts of these intensively managed plantations on soil functioning. To quantify the effects of eucalypt plantations on soil invertebrate communities, and to identify the main moderators driving these effects, we performed a meta‐analysis of studies reporting the effects of eucalypt monoculture plantations in comparison with other land use types involving different potential levels of disturbance to the soil matrix (native forests, other forestry plantations, croplands, grasslands, integrated crop‐livestock‐forestry, and invasive copses). We addressed these effects on the density (26 studies contributing 143 comparisons) and diversity (14 studies contributing 168 comparisons) of soil invertebrates. Density was lower in eucalypt plantations than in other forestry plantations, but higher than in grasslands and integrated crop‐livestock‐forestry. Diversity was lower in eucalypt plantations compared to native forests, yet higher when compared with other forestry plantations. When compared with other forestry plantations, the effects of eucalypt plantations on soil invertebrates depended on the type of other forestry plantation, the mean annual temperature, and the annual precipitation. Accounting for the diverse effects of eucalypt plantations relative to other land uses and climatic factors, along with the integration of data on soil physico‐chemical properties and different management practices, can contribute to a better understanding of how changes in land cover impact soil invertebrates and help managers to make informed decisions about the establishment of eucalypt plantations.
