Treeline in the mirror

Which photo has the treeline?

1. No treeline, the mountain is not high enough.
2. Treeline, the line above which trees no longer grow.

So, what is a tree line?

Well, Wikipedia can tell you; but the mountains I am looking at are in Switzerland so I’ll refer to the Department of Geography at the University of Zurich for the definition of a treeline.

A mountain treeline certainly is not a line in the common sense. The treeline is defined as the high elevation, climate driven limit of tree growth.

The treeline is the edge of the habitat at which trees are capable of growing. It is found at high elevations. Beyond the tree line, trees cannot tolerate the environmental conditions (usually cold temperatures, extreme snowpack, or associated lack of available moisture).

It is easy to get into the weeds discussing the geographical, botanical and topographical details of a treeline. Just look at the images above for a general idea and the graphic below for a summary.

But where does the mirror fit in?

A treeline is natural. It tells about interactions between ecotypes. And that makes me think. Is the treeline a vector or raster. Is it a thin line, a narrow path one pixel wide or is it a broad and wide line with varying gradients, blurs and opacities?

I think the latter. And looking in the mirror at treelines, I wonder…are human cultures like environmental ecotypes? Are they definable on their edges by lines? Raster or vector? Is diversity our strength…or our weakness…or is the effort to define cultural differences a non-sequitur?

In my book, Tangier Gardens, CJ faced incredible cultural challenges.

The Tangier gardens saved that young man from the relentless, brutal challenges issued by the northwest Africa landscape. It’s an intriguing story about culture, design and humans. 

Give it a go.
