I have a terrestrial acoustic monitoring situation that presents two challenges:
Acoustic monitoring is being conducted in an area with limited options for attaching the units (i.e., very few appropriate trees or shrubs to which the units might be affixed).
The sites occur on lands where permitting is required to put anything into the ground (i.e., driving a stake or u-post into the ground with a post pounder would require a time-consuming permitting process that creates admin. burden).
When there are no suitable existing structures, and it's undesirable to put a structure into the ground yourself, how do you deploy a terrestrial acoustic monitoring unit? One idea is to put u-posts/stakes into a concrete block and deploy them that way, but these are liable to tip over in the wind. How have others met this type of challenge?
