I'd like to follow-up with Greg or anyone else who has made artificial "trees" out of PVC or other materials. I have a perch population in my pond and was told they need a structure off from the bottom to string their eggs. Since we are in the doldrums of winter, it might be a good time for us members to work on projects such as this to install in the spring and enjoy the summer. So, any digital PHOTOS of "trees" or other easy and inexpensive artificial habitats to make would probably be most appreciated. There have been some fantastic ideas shared in this forum.
