>>867315I'm going to add a very specific thing related to this!
You can gather twigs, branches, pine cones etc. if they have fallen off a tree (that someone owns).
You can not take a single twig still attached to a tree because it is considered damaging the forest you are visiting.
>>868664How about one of those wood gas stoves + a Trangia burner? Stove can burn small wood pieces a bit more easily and in a controlled fashion while using the Trangia burner is still possible if wood isn't available and/or is too wet to use.
Or just use a gas burner, it's very effective and light.
