However, research has shown that Christmas tree plantations can provide a boost to biodiversity – especially in areas where it has been declining as agriculture becomes more intensified. This is because the plantations tend to have open habitat structures rich in bare ground, which can allow higher accessibility to food resources, while their trees can provide farmland birds with decent nesting conditions. They also tend to be less intensively managed than much industrialised agriculture, which also helps with food availability, while their fences can keep out the disruption from humans and dogs
