There's more to NIMBYism than saying "not in my back yard" in opposition to any development for any reason. A position isn't meaningfully NIMBY unless it is in opposition to an arguably good development for bad reasons. For example, it is NIMBYism to oppose the construction of affordable housing because you don't want to attract poor minorities to your neighborhood. In this case, a PV solar power plant might arguably be a good thing, but the reasons for opposing it, including the destruction of a rare ecosystem and a specific type of dangerous construction pollution, are more than fair.
