<p>Similar to your concrete block, but what about an umbrella stand with a pole in it? They are meant to not blow over and can come in quite large sizes that can be filled with sand or water.</p>

I would use these, they are also easily transported and do not give the impression of fixed installation.

<p>It may seem like a slightly peculiar option, but on one occasion I used an IKEA wooden (two-tier) step ladder. Since it's quite short, stable and has a good centre of gravity it was less liable to be tipped over by the wind or animals. I strapped an Audiomoth to one of its bracing columns and the recordings didn't appear to have any self-noise from the structure. Bearing in mind I did this in the Australian summer for a couple of weeks, so the risk of damp/rain affecting the structure long-term wasn't so much of an issue.</p>
<p>So if you're looking at something longer-term and more impervious to the elements, I suppose you could investigate a short metal stool or platform with a spot to attach a recorder. Maybe even a plastic stool which you could fasten to the ground with tent pegs or similar?</p>

<p>We have used a concrete block with a post mounted into it that can be carried, deployed, and recovered. You can make something similar using some plywood as a base.</p>

<p>I have a terrestrial acoustic monitoring situation that presents two challenges:</p>
<ol>
<li><p>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).</p>
</li>
<li><p>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).</p>
</li>
</ol>
<p>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?</p>

Where do you put a terrestrial recorder if you have no freestanding structures to attach it to, and also can't put a stake in the ground?

I have a terrestrial acoustic monitoring situation that presents two challenges:
