Impact of crop type on biodiversity globally

The negative impact of agricultural land on biodiversity is widely recognized. However, there remains a knowledge gap regarding the role of different crop types in maintaining biodiversity within the agricultural landscape. By extracting biodiversity data from global datasets and classifying different crop types, we quantified the contribution of different crop types to biodiversity. Our results indicate that biodiversity levels vary widely among crop types. We found a general loss of biodiversity when natural vegetation is converted to agricultural land, and highest losses in fiber crops, cereals and oil crops, and least in other crops (such as coffee or cocoa) and in mixed crops. In general, perennial crops retain more biodiversity than annual crops. Losses of biodiversity can be mitigated through mixed cropping of multiple crop types, especially by combining annual and perennial crops. The negative impact of converting natural vegetation to agriculture is greater in tropical than in ..., , , # Impact of crop type on biodiversity globally

## Description of the data and file structure

The data are extracted from PREDICTS dataset ([https://data.nhm.ac.uk/dataset/the-2016-release-of-the-predicts-database-v1-1](https://data.nhm.ac.uk/dataset/the-2016-release-of-the-predicts-database-v1-1)). 

Data is extracted from PREDICTS database (https://data.nhm.ac.uk/dataset/the-2016-release-of-the-predicts-database-v1-1). Detail information can be found in method section or reference (Hudson et al., 2014) .
