  1. Neighborhood Tree Canopy LAND 640 Final Project April29, 2008, Mike Droske Introduction Results Smallest subdivision: Plumtree Condos- 0.19 acres. % Canopy: 40.9% The purpose of this poster is to examine the neighborhoods of College Station, TX to determine which contains the highest percentage of tree canopy: an indicator of biodiversity and human well-being. Top 5 Subdivisions in Percent Canopy Literature Bottom 5 Subdivisions in Percent Canopy Methods • Digital Orthographic Quarter Quadrangle photographs were obtained from the TNRIS website for the area within College Station’s Extra Territorial Jurisdiction (ETJ). • The photographs were mosaicked using ERDAS Imagine software, and a supervised classification was performed to isolate the tree canopy in the photograph • Zonal attributes of the canopy image (canopy=1, all other features=3) were applied to the subdivision boundaries to obtain a percentage of canopy cover for each subdivision. Conclusion All subdivisions within the study area contained at least 20% canopy, and one contained 100%. There does not appear to be a strong correlation between percent canopy and subdivision area. Largest subdivision: Franklin Estates- 1480.46 acres. % Canopy: 71.9% References: Noss, R.F. “Indicators for Monitoring Biodiversity: A Hierarchical approach.” Conservation Biology. Vol. 4 #4.

  2. Neighborhood Tree Canopy LAND 640 Final Project April29, 2008, Mike Droske Correlation With Other Factors As an exploration of the relationship between tree canopy coverage and well-being, I plotted residential tenure against percent tree canopy. However, there was no apparent relationship between the two factors.
