ReplyDeletehistory of climbing (in) switzerland
nature in the mountains - seems redundant
history of hiking (in the) alps
picnicking in the alps - too narrow
mountainous flora and fauna - finesse wording

endangered species - doesn't work with your icons
alpine colonization (man and other animals) - loose this last part
