Two things were immediately apparent from the old photographs - less forest - tons of fruit trees
Fitting is also this anecdote I heard when visiting a historical mill. They had a huge linden tree in their yard, and they told us that in the olden days this was a symbol of prosperity, because the original owner showed off that they could afford to plant a useless, non-fruit-bearing - a status symbol.
Coming full circle - the best thing would be if we could plant tons of trees that also produce food - something like the baobabs https://en.wikipedia.org/wiki/Adansonia_digitata . E.g. pigs were fed oak's acorns in fall.

This is up from about 2% in the early 1800s, back when ships were built from wood, and firewood was used for heating. Funnily, the slow and steady build-up during those 200 years was partially motivated by the fact that when the British destroyed the fleet in 1807, there was simply not enough wood to build a new one.
People no longer use wood as a fuel, or in very small amounts compared to the past, and some former pastures have been re-colonized by trees.
Czechia is currently 34 per cent forest. Used to be less than 20 per cent in the Theresian cadastre (mid 18-th century).
