What types of ecosystems can be found in New Zealand?

New Zealand boasts a diverse range of ecosystems that reflect its unique geographical and climatic conditions. Coastal ecosystems, found along New Zealand's extensive shoreline, support a variety of flora and fauna adapted to marine environments. Forest ecosystems cover a significant portion of the land, including temperate rainforests that are home to a rich array of plant species and wildlife, such as the iconic kiwi.

Alpine ecosystems are prevalent in the Southern Alps, characterized by rugged mountains and specialized plant and animal life that thrive in high-altitude conditions. Wetland ecosystems play a crucial role in biodiversity, providing habitat for numerous species and acting as natural water filtration systems.

This combination of coastal, forest, alpine, and wetland ecosystems underlines the ecological richness of New Zealand, making it a destination with varied landscapes and organism interactions. Other options mentioned do not accurately represent the primary ecosystems found in New Zealand; for instance, deserts and tundras are not significant features of this region's environment, and the presence of specific ecosystems such as savannahs or taiga is not applicable to New Zealand’s ecological character.
