Do the Girl Scouts get the same sort of survival skills that Boy Scouts offer?
Hardly. Boy Scouts is far more outdoors/wildlife/survival oriented.
It's important to note that the Girl Scouts generally cap around the age of 14. If they wish to stay in the "scout" program, there's the Explorer/Venture programs which are indeed more survival/outdoor focused, and have been co-ed for at least the past the 20-someodd years.
I can't find the actual announcement on Scouting, but I'm reading as this change will allow girls into the Cub Scouts, which is the direct equivalent of girl scouts -- generally reserved for kids kindergarten age through 5th grade. After 5th grade, cub scouts can join into Boy Scouts, where girls will be split off into Girl Scout troops or merge into Explorer/Venture troops. And, notably, the Girl Scouts and female Explorers/Venturers will have the opportunity to earn the eagle scout rank within those organizations. Right now there's something that's similar in effort/requirements but has way less notoriety to it.
Cynically, this is more in wake of declining membership, so they're consolidating smaller clusters to maintain support and viability.
Girl scouts have one or two ranks that include theb14-18 year old range. Also, some one beat me to the Cub Scouts not Boy Scouts difference. As a dad of two cubs and a little girl who has fun at all the meetings, I look forward to this. ---
