Bill, christmas trees are only good as fish cover for 1-2 years (research I read about from Georgia when I was putting together my proposal). Once they lose their needles, the fish no longer use them. The best kinds of long term habitat cover is rubber tires, plastic items, or tree limbs. I suggested that Welland use tree limbs, because at the time I presented my proposal Welland was having a major die-off of ash trees, and their would have been lots of limbs available. I also suggested tires, and plastics that were being dropped off at Welland’s land fill site (e.g., old lawn furniture), as they make good long-term cover habitat.
