Finally, find out if the government agency managing your lakes allows Christmas tree recycling. It is illegal in some states to add artificial habitat of any kind into a waterway. Other states, such as those within the large jurisdiction of the Tennessee Valley Authority, require a permit to place artificial habitat.
There is also another option if you’d rather not do the work yourself. Many state agencies collect donated Christmas trees, and they have processes in place to make the most of the opportunity. Fisheries biologists can weigh in on the best locations for where habitat is most needed, or to create productive areas for specific species. Trees are also bundled to make large fish attractors. The idea is that larger structures attract more and bigger fish. The locations of the attractors are made available to the angling public in the form of GPS coordinates or maps.
In any case, there is a better option for disposing a used and live Christmas tree than the landfill. The fish will appreciate it, and so will you for the fishing success you can share with family and friends.
