In page Geography of Latvia:

"

About 10% of Latvian territory consists of peat bogs, swamps, and marshes, some of which are covered by stunted forest growth.[1] Forests are the outstanding feature of Latvia, claiming 42% of the territory.[1] Over the past 100 years the amount of forest territories in Latvia has doubled, and the process is still ongoing.[2] Forest territories are expanding naturally, as well as due to intentional afforestation of barren land and land that cannot be used for agricultural purposes.[citation needed] More than half of the forests consist of Scots pine or Norway spruce.[3][1]
