I'm not sure that matters. If you're holding your land to cash out on it in the future, it's going to get developed regardless. Whether the land remains undeveloped for an extra few decades seems like it makes little difference either way. Plus, not every property will be paved over edge to edge. Suboptimal locations will probably get developed into something which doesn't turn the land into something that completely destroys its ecological value.
