Pond Boss Forums Thread Like Summary - Are sycamore logs in pond OK?

I am planning on adding some large hollow sycamore logs to a pond as future catfish spawning structures. I know certain tree species can cause fish toxicity and am wondering if anyone knows if this is an issue with sycamore? The logs were recently cut from a live tree. Thank you in advance for your help.

I cannot vouch for the lack of toxicity , but I can add is...Sycamore wood is on the less dense side of the chart. They are not the worst choice. Cottonwood is a very light wood and has a pretty fast decomposition rate, for example. And, you cannot necessarily judge decomp on density alone. Western Cedar is less dense than Sycamore, but has other attributes that make its decomp rate much longer. I wouldn't give a cottonwood log but a few years in a pond and would not add them to my pond. The sycamore should go twice as long IMO.

Everything I've found says they're ok. If you want to be super safe, I'd just dry them out a bit before adding them to the pond.
