Lithuania

Relief

Underlying rock structures are of little significance for the contemporary Lithuanian terrain, which basically is a low-lying plain scraped by Ice Age glaciers that left behind thick, ridgelike terminal deposits known as moraines. The Baltic coastal area is fringed by a region characterized by geographers as the maritime depression, which rises gradually eastward. Sand dunes line an attractive coast; the Curonian Lagoon (Lithuanian: Kuršiu Marios), almost cut off from the sea by the Curonian Spit, a thin 60-mile (100-km) sandspit, forms a distinctive feature. It is bounded by the Žemaičiai Upland to the east, which gives way to the flat expanses of the Middle Lithuanian Lowland.

The lowland, consisting of glacial lake clays and boulder-studded loams, stretches in a wide band across the country from north to south; some portions of it are heavily waterlogged. The elevated Baltic Highlands, adjacent to the central lowland, thrust into the eastern and southeastern portions of the country; their rumpled glacial relief includes a host of small hills and numerous small lakes. The Švenčioniai and the Ašmena highlands—the latter containing Mount Juozapinė, at 957 feet (292 metres) above sea level the highest point in Lithuania—are located in the extreme east and southeast.

Drainage

Lithuanian rivers drain to the Baltic and generally have the slow, meandering characteristics of lowland rivers. The Neman River (Nemunas), cutting north and then west through the heart of the country, is the largest. Its main tributaries are the Merkys, Neris, Nevėžis, Dubysa, Jūra, Minija, and Šešupė. A distinctive feature of the Lithuanian landscape is the presence of about 3,000 lakes, mostly in the east and southeast. The boggy regions produce large quantities of peat that, dried by air, is used in both industry and agriculture.

Soils

Lithuanian soils range from sands to heavy clays. In the northwest the soil is either loamy or sandy (and sometimes marshy) and is quite heavily podzolized, or leached out. In the central region, weakly podzolized loamy peats predominate, and it is there that the most fertile, and hence most cultivated, soils are found. In the southeast there are sandy soils, somewhat loamy and moderately podzolized. Sandy soils in fact cover one-fourth of Lithuania, and most of these are blanketed by woodlands.

Climate

The climate of the country is transitional between the maritime type of western Europe and the continental type found farther east. As a result, damp air masses of Atlantic origin predominate, alternating with continental Eurasian and, more rarely, colder Arctic air or air with a southern, tropical origin. Baltic Sea influences dominate a comparatively narrow coastal zone. The mean temperature for January, the coldest month, is in the low 20s F (about −5 °C), while July, the warmest month, has an average temperature in the 60s F (about 17 °C). Average annual rainfall usually exceeds 30 inches (about 800 mm), diminishing inland. Rainfall reaches a peak in August, except in the maritime strip, where the maximum is reached two to three months later.

Plant and animal life

Lithuanian vegetation falls into three separate regions. In the maritime regions, pine forests predominate, and wild rye and various bushy plants grow on the sand dunes. Spruce trees are prevalent in the hilly eastern portion. The central region is characterized by large tracts of oak trees, with elegant birch forests in the northern portions, as well as distinctive black alder and aspen groves. Pine forests prevail in the south. Indeed, about one-third of the country is forested, and about another one-fifth is taken up by meadowlands. Swamps and marshlands account for only a small percentage of the total land.

Wildlife is very diverse and includes numerous mammalian species. There are wolves, foxes, otters, badgers, ermine, wild boars, and many rodents. The deep forests harbour elk, stags, deer, beavers, mink, and water rats. Lithuania is also home to hundreds of species of birds, including white storks, ducks, geese, swans, cormorants, herons, hawks, and even an occasional bald eagle. There are many types of grouse and partridge as well.

Ethnic groups, languages, and religion

Ethnic Lithuanians make up more than four-fifths of the country’s population; there are also Russians and Poles and lesser numbers of Belarusians, Ukrainians, Latvians, Tatars, Roma (Gypsies), and others. There was a significant Jewish community in Lithuania prior to World War II, and an influx of Jews from German-controlled Poland in 1941 boosted this population to nearly 250,000. By 1944, however, the majority of the population had been murdered, deported, or sent to concentration camps (see Holocaust).

The official language of Lithuania is Lithuanian. Russian, Polish, Belarusian, Ukrainian, and other languages are spoken in the larger cities. Yiddish is commonly spoken by members of the tiny remaining Jewish community in Lithuania.

Lithuania was the last pagan country in Europe, accepting Roman Catholicism in the late 14th century. About four-fifths of the population is Roman Catholic; there are smaller groups of Evangelical Lutherans and other Protestants, as well as people of other faiths. Elements of the pagan religion have survived in the countryside.
