Mountain Watch plant monitoring field guides and data sheets are in an Adobe pdf format. The field guide pages are first with every other page flipped so that when print it double sided on your printer it will line up when folded in half to form an  booklet (5.5" by 8.5"). The last 2 pages in the document are the field data sheet which also should be printed double sided.  You should take both the field guide and data sheet on your hike.  Please email us at AMCMtnwatch@outdoors.org if you are having difficulties printing these documents and would like us to mail you a copy.  Be sure to tell us which document you would like us to send.  Thank you for participating in Mountain Watch!
