One of the main drivers of extinction is habitat loss that arises when tropical rainforests are converted to farms -- a trend that is escalating at a dramatic rate. But are some farming practices less harmful to local birds and other wild animals? This was the question asked in a study recently published the journal Current Biology.
In this study, the authors recorded the overall diversity of bird species living on land-sharing cattle farms -- these appear to be wildlife-friendly because they include isolated trees and forest patches -- and compared it to land-sparing cattle farms that lack trees and forest patches and to neighbouring contiguous forest. The researchers found that land-sharing cattle farms retain less total bird biodiversity than do more intensive land-sparing cattle farms -- but only if the neighbouring contiguous forest is protected from human exploitation. Additionally, they found that overall avian biodiversity drops off faster for land-sharing cattle farms that are located farther away from contiguous forest.
