Effect of Environmental Variables in the Distribution of Tree Species in the Iguaçu National Park

A study on the Iguaçu National Park reveals that tree species distribution is significantly influenced by environmental variables such as altitude, humidity, soil fertility, aluminum saturation, and clay content. Using Canonical Correspondence Analysis (CCA), researchers identified specific patterns in how these factors shape vegetation across the park's diverse landscapes, ranging from riverbanks to plateau regions at altitudes between 150 and 750 meters. Notably, some species demonstrated tolerance to environmental variations, a trait common among widely distributed species. This finding underscores the importance of considering multiple environmental variables for efficient forest management and conservation efforts in degraded areas.
