The red deer in the Geneva basin live alongside highly-urbanized zones, making use of scattered woods bordered by the large, forested slopes of the Jura mountains. Within this landscape, red deer make daily movements between forest patches within the urbanized lowlands, and longer, seasonal migrations between the lowlands and the Jura mountains. There are two resident subpopulations, one living year round in the lowland and the other in the mountains. Only some individuals, mainly males, make seasonal migrations between those subpopulations. The red deer make two migrations in their annual cycle. The first occurs during the rut. In September, female deer from the lowlands concentrate in one larger forest patch and are joined by males moving down from the Jura mountains. After the rutting season, these males move back to the foot of the Jura mountains where they spend the winter. In March and April they migrate back to the higher elevation areas of the mountains following snowmelt. They spend the summer in these high elevation zones. In the sub-population that remains in the Jura mountains year-round, red deer make shorter migratory movements driven by snow depth.
