Biomes Are To Some Extent Subjective

It is important to emphasize once again that one biome does not suddenly give way to another over just a few meters, as we might expect from looking at a biome map. Instead of any sudden boundary, biomes tend to fade into one another over hundreds of kilometers. For example, as one moves over a long distance the trees in the forest may become on average more deciduous, or boreal conifers become more common in the vegetation. Patches of grassland mixed in with forest may become more and more frequent, or the trees may become more widely spaced. Biomes are at least in part an abstract human construct, something we use as part of our need to categorize the world around us so that we can work with it. As well as the fact that biomes tend to fade into one another, there is not even a clear and generally agreed definition of what each biome should "look like'' in any ideal sense. While there have been many attempts to try to pin the usage of biome categories down more precisely, none has succeeded because ecologists can have differing opinions on where one biome ends and another begins (especially if the ecologists come from separate continents).

Usually, they are loathe to give up using the definition they are familiar with, for one that someone else is trying to impose!
