Our current home sits on a quarter of an acre. We moved to the property in the summer of 2008. After some early mistakes (before I realized the impact Black Walnuts can have), we have managed to add enough natives to have some real improvements in soil composition, insect activity and diversity of wildlife. Here is a list of what has been incorporated--so far. :) [updated 8/08/2011]
