The expectation is simple: give nature more space, and biodiversity will increase. But reality is often not so simple. Across Europe, researchers and policymakers have repeatedly observed the same puzzling pattern.
Measures designed to benefit biodiversity can produce impressive results in one landscape while having only limited effects in another. Sometimes, the same intervention can even lead to contrasting outcomes depending on where it is implemented. For years, researchers have documented this inconsistency, but explaining it has been far more difficult.
Now a team of researchers from the Department of Agroecology at Aarhus University, led by professor Christopher John Topping, believes it may have found part of the answer. In a paper published in npj Sustainable Agriculture, the researchers introduce a concept called Functional Trait Capacity, or FTC for short. Rather than focusing solely on the biodiversity observed today, FTC estimates the range of life strategies that a landscape can support under specific environmental and management conditions.
The paper, "Functional Trait Capacity: from observing biodiversity to predicting landscape capacity" is written by Christopher John Topping, Tommy Dalgaard, Claus Rasmussen and Yoko Luise Dupont. The idea may sound technical, but its implications are straightforward: a landscape can hold far more ecological potential than current biodiversity surveys reveal. Most biodiversity indicators are based on observation.
Researchers count species, assess habitats or examine the functional traits of plants and animals already present in a landscape. These approaches have become increasingly sophisticated and remain essential for understanding the state of nature. Yet researchers argue that all these methods share a common limitation.
