Isn't that what rain and rivers are for? I mean, the trees you cut down were alive somehow, right? Or, are they planting them in places there never were trees?

- bell-cot 1y agoTrees vary considerably in their water needs. And even if you're planting species which fairly recently grew in the area - it's easy for a year or few of drought to kill off young trees, if those are not watered correctly and encouraged to establish large, deep root systems.
- moralestapia 1y agoWith that said ... it's completely possible to have trees within a city, even in arid places. I've seen it with my eyes!
- ac29 1y agoI live in a climate with a 6 month dry season. Established trees are fine with only rain, but new trees need 10-15 gallons a week of watering when its dry. Las Vegas only gets 4 inches of rain a year, so I imagine supplemental water is likely needed nearly every week for several years.
- defrost 1y agoIn some parts of the world clearing trees results in conditions that make it very hard to grow trees again for a considerable length of time. Large established trees with deep roots draw up large volumes of water from deep down. Once those trees go the water table rises, bringing salts from deeper down up to near ground leavel, the increased salt near surface inhabits young tree growth. eg: https://www.uwa.edu.au/news/article/2024/march/even-far-from-the-ocean-australias-drylands-are-riddled-with-salty-groundwater-what-can-land-managers-do https://www.uwa.edu.au/news/article/2024/march/even-far-from...
