Which environment would wildlife prefer, actively farmed and managed land, or untended natural land that to us might appear unkempt? Turns out that parts of the farm landscape that look overgrown and 'scruffy' are more important in supporting wildlife than they first appear, according to new research published today in Ecology Letters. The findings stem from an intensive study of an organic farm in Somerset by a team of scientists focussing on the complex ways in which animals and plants interact. First, the team of researchers from the University of Hull, the University of Bristol and the Centre for Ecology & Hydrology, created one of the world's largest terrestrial food-webs – a what-eats-what guide to the food-chain, and then developed a method of predicting what would happen to the whole food-web when habitats were lost.

Turns out that parts of the farm landscape that look overgrown and 'scruffy' are more important in supporting wildlife than they first appear, according to new research published today in Ecology Letters.
The findings stem from an intensive study of an organic farm in Somerset by a team of scientists focussing on the complex ways in which animals and plants interact.
First, the team of researchers from the University of Hull, the University of Bristol and the Centre for Ecology & Hydrology, created one of the world's largest terrestrial food-webs – a what-eats-what guide to the food-chain, and then developed a method of predicting what would happen to the whole food-web when habitats were lost.
They found that many types of insects and other animals have food sources in the apparently 'scruffier' parts of the farm such as field corners, the edges of farmyards and bits of 'wasteland' where old tractors and broken machinery slowly rust away.
The research, funded by the Biotechnology and Biological Sciences Research Council (BBSRC) and the Department for Environment, Food and Rural Affairs (Defra), also allowed the team to identify when different animal species would be made extinct by the loss of particular habitats, and which plants are the most critical in sustaining animal life.
Dr Darren Evans from the University of Hull, the lead-author of the paper, said: "This research has shown us how the biodiversity of a particular area can be affected by changes to its habitat. We discovered that the small patches of unkempt and weedy areas on a farm are actually hugely beneficial in supporting local ecosystems. Indeed, they even benefit animals that could benefit farmers by providing pollination and natural pest control."
