Introduction: Where have all the squirrels gone?

Squirrels are a common sight in many backyards across the world. They are known for their playful and energetic behavior and their ability to store food for the winter months. However, in recent years, many homeowners have noticed a decline in the number of squirrels visiting their yards. This decline has led to concerns about the health of squirrel populations and the impact on local ecosystems.

Climate change and its impact on squirrel populations

Climate change is one of the major factors contributing to the decline in squirrel populations. As temperatures rise, many squirrel species are finding it harder to survive. Some species are being forced to move to cooler areas, while others are experiencing changes in their food sources. For example, the red squirrel in the UK has suffered from a decline in the availability of spruce cones, which are a key food source. This has led to a decrease in their population and an increase in the population of the grey squirrel, which is better adapted to a wider range of food sources.
