Here's why:

* Elevation: Addis Ababa is located at a relatively high elevation (around 2,400 meters or 7,874 feet) which influences its climate and vegetation.

* Climate: The city experiences a temperate highland climate with distinct wet and dry seasons. The temperature remains relatively moderate throughout the year, although it can be quite cold during the winter months.

* Vegetation: The surrounding area is characterized by grasslands interspersed with woodlands and shrublands. You'll find trees like eucalyptus, juniper, and acacia, along with various grasses and flowering plants.

However, it's important to note that Addis Ababa is a densely populated city with significant urbanization. The natural vegetation has been significantly altered and replaced by built environments.
