The width of each corridor The length of each corridor The number of plants counted The quality of the corridor vegetation

Question 3What objection do critics raise against green corridors?

They cost more than building new parks They can spread disease and invasive species They attract too many visitors to cities They block railway lines and roads

Corridors were almost never used at night Narrow corridors were used surprisingly often Hedgehogs avoided urban areas entirely Wide corridors confused the animals
