Which of the following is NOT a restriction under conservation restriction?

A conservation restriction, often established to protect natural resources and promote environmental stewardship, places limits on specific activities to preserve the ecological integrity of a property. The correct choice indicates that planting trees is typically not restricted under these regulations. In fact, planting trees can be encouraged as it can enhance habitat, promote biodiversity, and contribute positively to the ecosystem.

On the other hand, construction of buildings, dumping of soil, and excavating or dredging are generally activities that could disrupt the intended conservation goals. These actions can lead to habitat destruction, pollution, and other forms of environmental degradation, which are precisely what conservation restrictions aim to prevent. Therefore, the focus of conservation restrictions is to limit these kinds of harmful activities rather than activities that contribute positively to the environment, such as tree planting.
