The Role of Climate in Shaping the Biodiversity of Iguazu National Park
Introduction
Iguazu National Park, straddling the border between Argentina and Brazil, is renowned for its stunning waterfalls and lush biodiversity. The climatic conditions of the region—characterized by high humidity, significant rainfall, and a warm subtropical climate—play a crucial role in influencing the park's diverse flora and fauna. Understanding this relationship is vital for appreciating the ecological dynamics at play within this UNESCO World Heritage site.
Details
-
Temperature Variability
- Average temperatures usually range from 20°C to 30°C (68°F to 86°F).
- Higher temperatures promote plant growth and the proliferation of life, creating a habitat conducive to various species.
-
Precipitation Patterns
- Annual rainfall varies between 1500 mm to 3000 mm, with the wettest months occurring from October to March.
- Such high humidity levels foster a rich ecosystem, where moisture-dependent plants thrive.
- The dense foliage of trees like the Brazil nut and various ferns provides habitat and food for many animal species.

Microclimates Within the Park
- Topography plays a significant role in creating microclimates, particularly near waterfalls and riverbanks.
- These areas support unique plant species and contribute to a diverse range of habitats for animals, such as certain amphibians and birds.
- For example, the cool mist from waterfalls can support species such as the capuchin monkey that prefer denser vegetation.
