Saving local forest

Hi everybody. Im from Portugal, and on case you haven’t heard about the wildfires here, just know we have One of the smallest countries In Europe, yet the biggest percentage of land burned in the continent.

I have been growing saplins from seeds Im my balcony and I have about 12 trees in my first year doing it (not great but I was a beginner), oaks, pines, chestnut. I want to ask you some tips for planting them, how I can protect them from the sun if everything else is burned ( animals are not a problem because they all probably died ), I fear i might plant them on the wrong spot or smth.

I would also like to get some tips on how to create a nursery for Young trees, because this year im planing on having 50+ new saplings. Thanks
