Have you found yourself working on a grant application or preparing a public presentation trying to figure out how to show what has happened to a space over time? Maybe you want to show the effects of invasive species and what an area might look like if brought back to pre-invasion status.
Google Earth’s Historical Imagery feature can help if the area is larger and viewable from above.
I recently worked with a fellow trustee of Littleton Conservation Trust to show the before and after views of 20 years of vegetation and development in an area. He was working on a grant application to try to secure some funds to restore this area to a true natural state, sans invasive species.
