The easiest way to tell us where any trees, blackberries, nettles or any other Oxford abundance is by zooming in on the map, moving the marker or writing an address. It won't show up on the map as we will keep it private, but we will need to contact you. Simply type in the address of the Tree; or grab the marker and drag it to the location you want it to be placed; or clear the map, click on the pointer icon and then you add it to the map in your desired location. You can also zoom into the map, and move it around by holding down your mouse button while moving it. Or you can use the arrows. Thank you!!
