In
this thread Chris K. made a very good point:
Spare blankets, tarps and even space blankets have a second use in sheltermaking. A secondary roof in hot climes will greatly help to reflect and reduce heat from the sun. In all climes a second layer will also create a still air pocket with increased insulation...
This prompted me to post some thoughts I had recently after reading
Peter Kummerfeldt's excellent book on survival. One of Peter's main points is that relying on bushcraft for survival is sketchy because successful bushcraft requires 1) prior knowledge & practice 2) plentiful natural materials 3) hours of time to execute 4) cutting tools and 5) a (relatively) uninjured survivor.
My thought is that while I certainly don't want to rely 100% on bushcraft, I believe that knowing
and practicing bushcraft then combining it with readymade gear (tarps, firestarters, etc) gives the survivor another advantage in the fight to live.
Chris brought up the perfect example: shelters. If all you have is a tarp or 55gal plastic liner, you have no insulation. If all you have is bushcraft, you will have to have lots of materials and time to even approach a wind/waterproof shelter. But, if you know bushcraft AND you have the tarp you can use bushcraft to develop some insulation then add the tarp to thoroughly keep out the wind & water. If due to circumstances (time, injury, etc) you can't execute the bushcraft then your space blanket or bivy bag will give you a chance to get by.
I believe that it is a mistake to completely reject bushcraft, just as it is a mistake to completely reject modern survival gear.
