Happy 2022! I wanna find out how can we put our old Christmas trees into our ponds, lakes, streams and rivers to help fish and other aquatic critters for shelter for breeding and protection from predators. I've never done it before in my backyard when I had my pond. I wanna find out which types of Christmas trees are safe for underwater creatures. Please let me know in this forum if you all have anything to add. Out!
I love the idea, but I would have some serious trepidation about it. Alas, most Christmas trees are sprayed with various herbicides and pesticides, the main eight being chlorothalonil, atrazine, simazine, glyphosate, hexazinone, carbaryl, chlorpyrifos and dimethoate. Several of these are known to pose extreme harm to aquatic organisms. Of course, we really have no way to know how much residue from these chemicals remains on the trees. It is known that many of these chemicals cause harm in very small doses. To me, it doesn't feel worth the risk. So I personally choose to err on the side of caution and avoid these trees. Even though it pains me greatly to see all the potential habitat for wildlife laying on the curb, bound for the dump. If it weren't for the chemicals, I would have a grove of old Christmas trees set up in my yard.
Obviously, if you could find trees that were organic or you could be certain had not been sprayed, I would say go for it. They seem to be somewhat tough to find though.
