Sarah - Nice job. I do think this might be a first. We've certainly created a lot of presentations and facilitated a lot of workshops, but I don't know that we've ever created a poster.
What you have included is great. My biggest concern is that there's a lot to read and some of the text seems small (at least on my computer). I might think about taking out one of the sample Guidelines in Practice pages and I might take out one of the Sample Guidelines pages - just to provide an opportunity to make the font size a bit bigger and provide a bit more white space. In reality, I don't think most people will read these pages. My guess is that they will skim the formatting. If you are going to be hosting the poster, you could have a copy of the guidelines to show anyone who seems particularly interested and/or hang a couple of same pages next to the poster (obviously, this all depends on the set up and you don't want the samples to walk away).
Although I always like having background on the project (and appreciate that you did), I might think about cutting the introductory paragraphs down a bit - perhaps deleting the first sentence of the second paragraph and leading with ... Quality environmental education programs...
That might allow you to increase the font a bit. In particular, if you can increase the font, I'd try to increase the font on the sentence: The Community Engagement Guidelines focus on ... I might even bold it. It's kind of the theme sentence.
Finally, you probably know this audience. But, I wonder if they think of themselves as environmental educators? We did a workshop on the Community Engagement Guidelines with forest professionals last year. We edited some of the language to talk about 'educators' and 'professionals.' We wanted to make sure the group thought of this as applying to their work and not just something an "environmental educator" might do.
It will be great to hear how this goes. The poster is a great idea and looks quite professional.
