Planting density inconsistency #20

Closed kessl closed 4 years ago

kessl commented 5 years ago

I stumbled upon an inconsistency in the planting density fields - I couldn't figure out how the values in acres and square meters relate.

Take for example the American Hornbeam (https://trefle.io/api/plants/117252): planting_density_minimum: sqm: 2832802, acre: 700

700 trees per acre amount to 5.78 square meters per tree. 2 832 802 per square meter is obviously too many. If I assume 'sqm' refers to a square kilometer, I get 35.3 square meters per tree.

What am I missing?

Hey @kessl , seems to be an issue indeed. We'll dig into it
