A rainforest is an area of tall, mostly evergreen trees and a high amount of rainfall.
Rainforests are Earth’s oldest living ecosystems, with some surviving in their present form for at least 70 million years. They are incredibly diverse and complex, home to more than half of the world’s plant and animal species—even though they cover just six percent of Earth’s surface. This makes rainforests astoundingly dense with flora and fauna; a 10-square-kilometer (four-square-mile) patch can contain as many as 1,500 flowering plants, 750 species of trees, 400 species of birds and 150 species of butterflies.
Rainforests thrive on every continent except Antarctica. The largest rainforests on Earth surround the Amazon River in South America and the Congo River in Africa. The tropical islands of Southeast Asia and parts of Australia support dense rainforest habitats. Even the cool evergreen forests of North America’s Pacific Northwest and Northern Europe are a type of rainforest.
Rain forests’ rich biodiversity is incredibly important to our well-being and the well-being of our planet. Rainforests help regulate our climate and provide us with everyday products.
Unsustainable industrial and agricultural development, however, has severely degraded the health of the world’s rainforests. Citizens, governments, intergovernmental organisations, and conservation groups are working together to protect these invaluable but fragile ecosystems.

Continents and countries where they are found.
Named examples
Tropical rainforests are characterised by their unique spatial patterns and dimensions, encompassing a range of features such as location, altitude, latitude, size, shape, and continuity. Here are some key aspects to consider:
Location:
Tropical rainforests are typically found in equatorial regions, situated between the Tropics of Cancer and Capricorn. They are distributed around the globe in countries near the equator, such as Brazil, Indonesia, Congo, and Malaysia.
Altitude:
Tropical rainforests are generally located at low altitudes, with the majority occurring below 1,000 meters (3,280 feet). They thrive in warm, lowland areas where temperatures remain relatively consistent throughout the year.
Latitude:
Tropical rainforests are concentrated near the equator, where there is a consistent amount of sunlight year-round. The equatorial climate contributes to the high biodiversity and productivity of these ecosystems.
Size:
Tropical rainforests are extensive, covering large areas of land. The Amazon Rainforest, for example, is the largest tropical rainforest and spans multiple countries in South America. The size of these rainforests contributes to their ecological significance and the vast array of species they support.
Shape:
The shape of tropical rainforests can vary, influenced by factors such as topography, river systems, and historical climate conditions. The Amazon Rainforest, for instance, has a complex and irregular shape shaped by the Amazon River and its tributaries.
Continuity:
Tropical rainforests often exhibit a continuous and dense canopy, providing a seamless layer of vegetation. This continuity contributes to the unique microclimates within the forest and facilitates the complex interactions between different species.
Understanding the spatial patterns and dimensions of tropical rainforests is crucial for both scientific research and conservation efforts. These ecosystems play a vital role in global biodiversity, carbon sequestration, and climate regulation, making it important to monitor and protect them from various threats such as deforestation and climate change.
In the context of rainforests, continuity generally refers to the uninterrupted and sustained presence of certain ecological processes, species, or habitats over time. It emphasises the persistence and interconnectedness of various elements within the rainforest ecosystem.
For example, forest continuity may refer to the uninterrupted presence of a dense and diverse canopy cover, which is a characteristic feature of healthy rainforests. This continuity is important for maintaining the complex interactions between different species, including plants, animals, and microorganisms, which contribute to the overall biodiversity and ecological balance of the rainforest.
Additionally, continuity may also be used to describe the ongoing existence of specific plant or animal species within the rainforest. The continuous presence of key species is crucial for ecosystem functioning, as they often play vital roles in processes such as pollination, seed dispersal, and nutrient cycling.
Human activities, such as logging, agriculture, and urbanisation, can disrupt the continuity of rainforest ecosystems, leading to habitat fragmentation, loss of biodiversity, and changes in ecosystem dynamics. Conservation efforts often aim to preserve the continuity of rainforest ecosystems to ensure their long-term health and sustainability.
