The Forests

These forests are found in Canada, Europe, Asia, and the United States. So it is clear that coniferous forests are not found in Amazonia (Brazil). Rather, tropical evergreen forests are found in Amazonia (Brazil).

Types of Coniferous Forest:

• Northern Coniferous Forests (Taiga): Found in the northern regions of North America, Europe, and Asia, including Canada, Scandinavia, and Siberia. The taiga is the world's largest terrestrial biome, known for its cold winters, short growing seasons, and primarily coniferous tree species, such as spruce, fir, and pine.
• Montane Coniferous Forests: These forests are found at high altitudes, often in mountainous
  regions around the world. Montane coniferous forests have cooler temperatures and shorter growing seasons. They contain conifer species like subalpine fir, Engelmann spruce, and mountain pine.
• Temperate Coniferous Forests: Located in temperate regions with milder climates, such as the
  Pacific Northwest of North America and parts of Europe and Asia. These forests have a mix of coniferous and broadleaf trees, including species like Douglas fir, western red cedar, and Sitka spruce.
• Tropical Coniferous Forests: Found in some high-elevation regions of the tropics, like the Sierra
  Madre Oriental in Mexico. These forests are unique because they occur in tropical regions, but the elevation brings cooler temperatures. They often feature conifer species adapted to these conditions.
• Sclerophyllous Coniferous Forests: Found in regions with a Mediterranean climate, including parts
  of California, Chile, and parts of Australia. These forests have conifers like Monterey pine and cypress, along with drought-resistant shrubs and hard-leaved plants.
• Alpine Coniferous Forests: These forests are located at high altitudes in alpine or subalpine zones around the world. These forests are adapted to extremely harsh conditions, with stunted, wind-sculpted coniferous trees like the whitebark pine and alpine fir.

The country experiences a warm and humid climate, with temperatures ranging from the low 60s to the low 100s Fahrenheit (mid-10s to upper 30s Celsius) and high relative humidity.

Forests:

A broad belt of dense forest covers nearly one-third of the country, extending north of the lagoon region in the east and reaching down to the coastline in the west between the Sassandra River and the mouth of the Cavally River.

The Taï National Park, located in the southwest, protects the largest area of forest remaining in the Upper Guinean rainforest belt of West Africa.

The vegetation is predominantly dense evergreen ombrophilous forest with emergent trees up to 60 m (200 ft) tall, with massive trunks and large buttresses or stilt roots. Ivory Coast is a major producer of cocoa, a major national cash crop.

So, Assertion (A) is wrong. Primary productivity of tropical rainforest (2200 gram biomass per square meter/year) is greater than all other types of forests. It is greater than temperate forests (1320 gram biomass/square meter/year) also. Thus reason (R) is true.

When rainforests are cleared, the soil is exposed to intense rainfall and sunlight, leading to erosion and further nutrient loss. The combination of nutrient-poor soil and the difficulty of establishing new trees in such conditions makes regeneration of a tropical rainforest much slower than that of a tropical deciduous forest.

Tropical deciduous forests, which experience a distinct dry season, tend to have more fertile soils, and the trees are adapted to survive and regenerate more readily in such conditions.

Notably, tropical rainforests have higher temperatures and more moisture than the other regions, which accelerates the decomposition of dead organic matter in the soil and releases nutrients more rapidly.

According to the World Food and Agriculture Statistical Yearbook-2023 (Data-2021) United States is the top wood pulp producing country with 49,685 Million Tonnes in 2021. Brazil, China, Canada, Sweden and Finland were at second, third, fourth, fifth and sixth place respectively.
