According to responsible environmental management practices, what must occur if native acreage decreases on a golf course?

When considering responsible environmental management practices on a golf course, maintaining ecological balance is key. If native acreage decreases, a proportional decrease in managed turfgrass is necessary to ensure that the ecosystem remains sustainable and that biodiversity is preserved. This approach helps to mitigate negative impacts on local flora and fauna, as reducing turfgrass can enable the restoration of natural habitats and promote the growth of native species.

By managing the proportion of managed turfgrass in relation to native acreage, golf courses can foster a healthier environment, as turfgrass can often compete with native plants for resources. This method not only supports environmental sustainability but also aligns with modern practices that emphasize the importance of conservation and responsible land management in the maintenance of golf courses.

In contrast, other options suggest either no change or adjustments in areas not directly aligned with reinstating ecological balance. For example, increasing native species without addressing managed turfgrass could lead to an imbalance, and focusing solely on water usage does not directly address the core issue of native habitat loss.
