DESCRIPTION:Just over the past half year\, the field of remote sensing for
  forest monitoring has witnessed a number of revolutionary developments\; 
 we are now navigating an exciting era of space-based forest monitoring in 
 which free\, moderate-resolution images of our entire planet have become i
 ncreasingly accessible to the public at large. In this presentation\, I fi
 rst explore three different land classification-based approaches to forest
  monitoring in order to demonstrate a range of methodologies currently in 
 practice that employ remotely sensed satellite images to inform forest con
 servation efforts. I then apply one of these methodologies to quantify spa
 tial patterns in deforestation across a representative global network of t
 ropical forest protected areas and\, further\, relate these spatial defore
 station patterns with ecosystem health indices associated with each reserv
 e. I find that\, globally\, deforestation rates outside of tropical forest
  protected areas since 2000 have exceeded those inside their administrativ
 e boundaries\, an indication of the relative efficacy of tropical forest r
 eserves in at least tempering drastic land-cover changes within the areas 
 that they enclose. However\, I also find that\, globally\, positive defore
 station rates both inside and outside tropical forest protected areas sign
 ificantly correlate with declining ecosystem health. Overall\, my research
  offers insight into the general performance of protected areas in tropica
 l forests worldwide\, while simultaneously demonstrating the utility in ap
 plying recently developed satellite imagery analysis technologies to condu
 ct tropical forest conservation studies on a global scale.
