Next on our lengthy itinerary for today was Drumlanrig Castle. By now it was well past closing time, but we cheekily drove up the driveway anyway to take a quick picture of this magnificent 17th century Renaissance palace, now part of the Duke of Buccleuchâs estates.
Grass Patches... and a Few Trees. The savanna is characterized by its variety of grasses. However, it is not the lush grasses of grasslands that extend as far as the eye can see.

Grass-dominated ecosystems that contain a significant number of widely spaced trees are termed savannas. Trees may make up as little as 5 percent or as much as 30 percent of the cover of all plants in savannas, but grasses and grasslike plants form a continuous ground cover. Originally, savanna was a term used to describe primarily tropical and subtropical grasslands, which usually have more woody plants than temperate grasslands. These tropical and subtropical savannas occupy large land areas. Almost 65 percent of Africa is covered by savanna, much of the northern region of Australia has savanna vegetation and South America has extensive savannas. Worldwide, estimated land cover by savanna is nearly 20 percent.
