To me it seems more likely that this person is misreporting their motive than that they really oppose this allocation of a patch of grass on biodiversity grounds. I would expect grounds like “I want to use it myself” or slightly more general “it should be available for a wider group” to be very much more common, for example if I had to rank likelihood of motives after hearing that someone objects, but before hearing their reasons. I’d end up with more weight on “playing social games” than on “earnestly believes this”.
On the other hand it would not surprise me very much that at least one person somewhere might truly hold this position. Just my weight for any particular person would be very low.
