Mosquitoes are vectors for pathogens such as the West Nile Virus, Dengue (DV), Zika (ZIKV), and Malaria. Determining the abiotic factors that contribute to the spread of these diseases and the conditions under which mosquito habitats thrive is essential to mitigating mosquito populations and mosquitos as a public health threat. This study aims to assess the effect of tree density and land cover on mosquito populations and the correlation between tree density and mosquito species composition. Using photos collected from NASA GLOBE Observer, we investigated three different three-by-three-kilometer areas of interest (AOI) representing various ecological settings within the surrounding Houston, Texas area. These photos were then analyzed using a GitHub machine-learning model that assessed both tree density and land cover percentages within each region. This data was then compared to an ArcGIS database representative of the mosquito population dataset of Houston, Texas. From this data, we found no clear correlation between either tree density or concentration with mosquito populations, but previously published works from other authors support the idea of a positive relationship between mosquito populations and urbanized areas with fewer trees.
