Data

Where did the data come from?

The data used for analyzing Barn Swallow abundance as well as insect abundance was taken from various sources (see below). The first source of data was given by the client, GPS points and 11 paper maps for specific agricultural sites in Metro Vancouver were provided from which analysis had to be done. The second source of data included Metro Vancouver ecosystem analysis. This data had classifications of different ecosystem around Metro Vancouver. As well as data on different forest types and vegetation cover. Furthermore, some data was taken from the Simon Fraser University database such as parks and pests infestation.
