I just went to the Conservation Department's website, to try to look up ordering information for the book and saw they have it there available in PDF by "chapter" (they're not exactly chapters, but short sections about each type of plant). FREE
But still, I like having the book in hand. It's nice to be able to take it out on a hike. It does have color drawings of some of the plants about two-thirds into the book, but there is a sketch line-drawing throughout the book as it presents each plant.
