In Italy, the red squirrels live in any kind of forest, if there is a sufficient number of trees that can produce seeds (starting from 20-30 years of age, depending on the species of tree) necessary for their nutrition. Therefore we can find them in mixed deciduous forests, coniferous and deciduous woods or conifers only. Generally, the best forest habitats are composed of multiple species of trees, so that every year there are some tree species that produce enough seeds.
