Summary edit
| Description |
English: The roads are powerful factors of landscape fragmentation, because they scare away animals and/or because of the inconvenience and the artificial landscape. , In addition, animals are being crushed by vehicles. (roadkill). Propagules of plants or of certain lichens can hardly pass through ou not pass.
Roadside seem to be good as green corridors, but they are polluted by exhaust gas and catalytic materials, and the risk of roadkill and predation is increased (lack of caches) For animals who refuse to cross a road, three or four intersecting roads are the equivalent of an "ecological island" which they can not escape. Millions of these islands were created by road Français : Les routes sont de puissants facteurs de fragmentation du paysage, soit parce qu’elles font fuir les animaux à cause du dérangement et de l’artificialisation du paysage, soit parce que les animaux s’y font écraser (roadkill). Les propagules de plantes ou de certains lichens peuvent aussi difficilement les traverser. Les bords de routes semblent être de bons corridors, mais ils sont pollués par les gaz d’échappements et matériaux catalytiques, et le risque de roadkill et de prédation y est accru (manque de cachettes) Pour les animaux qui refusent de traverser une route, 3 ou 4 routes qui se croisent forment l'équivalent d'une "île écologique" dont ils ne peuvent pas s'échapper. Des millions de ces îles ont été créée par le réseau routier |
