I'm offered a camping option to spend a night directly in desert and dunes near Dubai (Al Qudra Lake).
Should I have any concern about animals or species (scorpions, ants or other insects) or is there any thing specific, that I should take special care off, when planning such over-night stay there?
You should wear your shoes at all times. There could be scorpions. Problems aren't happening so often with those but you'd better be on the safe side.
This post gives a good overview of all the risks you might be facing there : http://www.thenational.ae/news/uae-news/desert-survival-please-do-not-touch-the-scorpions
