The main threats to forest ecosystems include deforestation, climate change, invasive species, and urban development. Deforestation directly reduces forest cover, leading to habitat loss for countless species and disrupting ecosystem functions. Climate change affects temperature and precipitation patterns, impacting species survival, forest health, and the overall stability of these ecosystems. Invasive species can outcompete native flora and fauna, leading to declines in biodiversity and altered ecosystem dynamics. Lastly, urban development encroaches upon natural habitats, fragmenting forests and further threatening the biodiversity that relies on these ecosystems.

In contrast, other options mention increased rainfall, biodiversity, greater forest density, and healthy wildlife populations, which are generally positive attributes for forest ecosystems. The mention of only forest fires and storms as threats overlooks the broader spectrum of environmental changes and human impacts that significantly endanger forest ecosystems. Thus, understanding the complexity and interrelation of various threats is crucial for effective forest management and conservation.
