comment Ecological geospatial conundrum
KDEs might be inappropriate here since change in tree location and numbers will change the bandwidth and therefore the results. Have you considered creating a zonal raster of arbitrary size (say 100m x 100m) and getting trees / cell and tree area / cell for each time and then calculating a difference between times?

comment I'm having trouble with getting a shapefile in the right projection. What am I doing wrong?
Are you sure you're mapping the x & y fields correctly? A straight line would indicate you're mapping both to the same field, regardless of what else is happening.
