Rarely to be taken seriously

I was being jokey... but one could well make the case that within the range of auropectoralis alone the highland dry grassland and low coastal plain grassland represent different types of grassland habitat, and there may be others I'm not familiar with. And then you can contrast that with the true Chihuahuan semi-desert habitat and then the pastureland that ssp. lilianae is commonly found in.Is there a justification for writing 'grasslands' in the plural ?
