What is one of the ecological benefits of planting native species?

1. Reduced maintenance requirements

2. Increased dependency on fertilizers

3. Support for local wildlife and pollinators

4. Higher water usage

The correct answer is: Support for local wildlife and pollinators

Planting native species offers significant ecological benefits, particularly in supporting local wildlife and pollinators. Native plants are well-adapted to the local environmental conditions and have evolved alongside native insect populations, birds, and other fauna. This creates a mutually beneficial relationship where the plants provide essential resources, such as food and habitat, for local wildlife. For example, many native plants produce nectar that is crucial for pollinators like bees and butterflies, while their seeds and foliage serve as food sources for various birds and small mammals. Moreover, native plant communities promote biodiversity by supporting a range of species, which can lead to healthier ecosystems. They often require fewer resources than non-native species, as they are adapted to the local soil types, pest pressures, and climate, which enhances the overall resilience of the ecosystem. In contrast, options that suggest increased dependency on fertilizers or higher water usage do not align with the ecological philosophy of promoting native plants, which typically thrive on natural soil nutrients and moisture levels. Additionally, the idea of reduced maintenance is a benefit but is more of a management consideration rather than a core ecological advantage compared to the vital support native species provide to local wildlife.
