Evidence

Peer-reviewed

Geography

Friuli Venezia Giulia lowlands, northeastern Italy

System

Ecological networks / woodland / meadows

## WHAT THE EVIDENCE SAYS

Sampling 219 plots across 87 nodes in a 298-km² ecological network, researchers counted 443 plant species, 47 alien. Peripheral, less-connected nodes supported high native richness and uniqueness; alien richness depended strongly on land-cover composition and edges, especially within fragmented woods.

## WHY IT MATTERS / OUR READ

A green corridor is not automatically a complete conservation gain. Plans should evaluate native and introduced communities, landscape edges and patch position, rather than relying only on structural connectivity scores.

## CAVEATS / UNCERTAINTY

Correlational landscape study, not an experiment in adding or removing corridors. Patterns are habitat-dependent and alien-community similarity does not alone prove entire floras homogenized.
