Refreezing is fine for safety (if you thawed it correctly). The main reason not to freeze and thaw things multiple times is that tiny ice crystals do damage to the structure of the food each time freezing happens.
In meat, that damage makes your meat dry out easier when cooking. That’s normally a bad thing, bit it might actually be a good idea for making jerky.
In short, I would have no hesitation using refrozen meat to make jerky
You can look at wildlife/pollinator gardening. There are different focuses like rewilding or even restoration. There are also a lot of companies willing to sell incredibly invasive plants while calling them nice things, so buy from a reputable source if you do buy plants or seeds.
