Day 1

Today we made our ecocolumns with all sorts of stuff in it. The bottom is the aquatic layer with a leach and tadpole along with some aquatic plant. Above that is the decomposition layer where we have several bugs. The next layer up is soil and some plant life. We need to bring in a predator to put in the plant layer so that the ecosystem is not thrown off by too many flys.

In the decomposition layer, there is a millipede from my backyard. I know they eat a lot of plant material so I hope it helps to decompose that layer. I got this material from a pile of leaves that is in the woods at the edge of my yard. We just dumped the leaves there about 2 1/2 months ago, so I was surprised to dee that it was already pretty decomposed underneath the top layer. I was also not expecting to find as many living things in it as I did. There were several little bugs that I noticed after I put it into the ecocolumn. The millipede just happened to be underneath where I grabbed and there were a lot of doodle bugs.
