  "account": "South African macadamia plantations could benefit from bats and birds as natural pest control, according to a recent study. Labor-intensive harvesting and complex processing make macadamias one of the most expensive nuts globally, making pest protection crucial. An international research team led by the University of Göttingen investigated the impact of natural vegetation, specifically bird and bat populations, on pest infestation. The findings, published in the journal Agriculture, Ecosystems and Environment, demonstrate that higher bat activity correlated with reduced pest infestation, and yields increased in landscapes with more natural vegetation. Excluding bats and birds increased insect-damaged nuts from 6.2% to 10.7%. Higher bat activity was associated with lower insect damage, and natural habitats increased bat abundance and diversity. The study highlights the importance of natural habitats, comprising around 60% of the landscape, for agricultural production and biodiversity.",
