Mazandaran is located on the southern coast of the
Caspian Sea. It is bordered clockwise by
Golestan,
Semnan, and
Tehran provinces. This province also borders
Qazvin and
Gilan to the west. Mazandaran province is geographically divided into two parts: the coastal plains and the mountainous areas. The
Alborz Mountain Range surrounds the coastal strip and the plains abutting the Caspian Sea like a huge wall. Due to the prevailing sea breeze and local winds of the southern and eastern coasts of the Caspian Sea, sandy hills are formed, causing the appearance of a low natural barrier between the sea and plain. There is often snowfall in the
Alborz regions, which run parallel to the
Caspian Sea's southern coast, dividing the province into many isolated valleys. The province enjoys a moderate, subtropical climate with an average temperature of 25 °C in summer and about 8 °C in winter. Although snow may fall heavily in the mountains in winter, it rarely falls at sea level. File:Noor Caspian sea.jpg|Caspian Sea coast at

Caspian Hyrcanian mixed forests •
Elburz Range forest steppe The total wood production from these forests is estimated at .
Golestan National Park and Shastkolateh forest watershed are located in Golestan Province and Mazandaran Province (the total area of the Hyrcanian forest is estimated at . From these forests, are used commercially, are protected and the rest are regarded as forest lands or over-used forests. The total of the forest woods used in this province is estimated at . The Kojoor, Dohezar and Sehezar forest watersheds are located in Mazandaran Province. The Elburz Range forest steppe
ecoregion is an arid, mountainous 1,000-kilometer arc south of the
Caspian Sea, stretching across northern
Iran from the
Azerbaijan border to near the
Turkmenistan border. It covers and encompasses the southern and eastern slopes of the
Alborz Mountains as well as their summits. The
Caspian Hyrcanian mixed forests ecoregion, with its lush green mountainsides and plains that receive moisture from the Caspian Sea, forms this ecoregion's northern border. The vast Central Persian desert basin ecoregion forms its southern border. The Alborz range is composed of a
granite core overlain with
sedimentary rock including
limestones,
shales,
sandstones, and
tuffs.
Metamorphic rocks such as
schists,
marbles, and
amphibolite are also widely found. The climate is arid with annual precipitation varying from 150 mm to 500 mm, falling mostly as winter snow.
Environment The now-extinct
Caspian tiger and the
Caspian horse are two of the animals of Mazandaran province. The 1971
Ramsar Convention on Wetlands of International Importance especially as Waterfowl Habitat was held in Mazandaran in the city of
Ramsar. Unlike the rest of Iran, Mazandaran is watered by numerous rivers, or mountain torrents, all running from the mountains to the sea. The German traveller
Samuel Gottlieb Gmelin, who visited this country in 1771, says that in the space of eight miles, on the road from Resht to Amot, 250 of such streams are to be seen, many of them being so exceedingly broad and deep, that the passage across is sometimes impracticable for weeks together.
Climate mountain range in Mazandaran Province Mazandaran Province naturally comes under the influence of the geographical latitude, the Alborz mountain range, elevation from sea level, distance from the sea, and the southern barren areas of Turkmenistan, local and regional air currents, and versatile vegetation cover. These conditions result in the climatic division of the province into three types: Moderate Caspian climate with hot, humid summers and mild, humid winters. This climate is found in the western and central plains of the province between the Caspian sea and the foothills the Alborz mountains. Rainfall is significant in this climate zone and is highest in autumn. the annual accumulation decreases from west to east. Frost occasionally occurs during winters. moderate mountainous climate generally in the altitude between meters and is characterized by a decrease in both precipitation and monthly temperatures. winters are long, cold and freezing and summers are mild and short. Cold mountainous climate with long freezing winters with long periods of frost and short cool summers. There is often snowfall during most of the seasons in the latter region, which continues till mid-summer. The climate is mainly found at an altitude above , such as the top of
Mount Damavand and
Alam-Kuh, where the conditions are suitable for
