Defining Biodiversity

When initially asked to define biodiversity, I wrote the following: The vast and varying collection of species and the ecosystems they comprise". I did a little digging around online and most of the definitions aren't terribly different than this. The one thing thing I didn't account for in my initial post was that biodiversity is also the INTERACTIONS between the entities I described.

There is a popular (as opposed to peer-reviewed) article about biodiversity and WHY IT MATTERS that's worth a quick read.

invasive and exotic species!

Image
I've just finished reading through hundreds of web pages on exotic species in Florida. It was clearly not enough because Florida has a HUGE invasive species problem. I created a slideshow (embedded below) that I can use when sharing this information in person, but I invite you to click through and see a brief smattering of what some of the heavy duty invasives down here are. Think of it as a dirty dozen of invasive species. If you want some more reading (ok fine, looking at pictures) that you don't have to search for yourself, check out this link that's part of the University of Florida network. If you're feeling particularly sciency, this link will take you to Florida's list of invasive plants that are sorted by how good they are at destroying the world around you  how much of an impact they can cause. If the presentation doesn't make much sense not in person, and you don't care to click the links, at least check out this infographic:

creating a nonprofit for fun! and profit?

Last week I did a post about what a friends group geared towards the Wacissa River might look like. This week I take it a step further and research what it takes to form a nonprofit in Florida. Google searches brought out all sorts of websites. Like any grouping of search results, most weren't helpful or were full of junk. A few, however, actually gave some insight as to what it would take to get this thing up and running! The Florida Department of State, as you might expect, has the official methodology buuuut, it's certainly not the most user friendly of language, websites, or what actually needs to happen. There are two other websites that I stumbled across that, although not official, gave very helpful information as to what would actually need to happen. On that note, I've taken steps from all three sites and put them together into what you see below. At the end of the post, you'll see a smattering of links that will get you to where this information came from. Som...

Study Area Rationale

The Florida National Scenic Trail (FNST) is a nationally designated scenic trail covering over 1,500 miles from Big Cypress National Preserve to Gulf Islands National Seashore. Of the 11 national scenic trails, it's one of only three that is entirely contained within one state. My study area focuses on a portion of the trail running just over 80 miles through St. Marks National Wildlife Refuge and Apalachicola National Forest. Why have I chosen not only this trail but this particular section. My reasoning is two fold. I. Visitor Use and Experiences ====================== It's estimated that over 300,000 people use the trail in some capacity each year ( pdf source ). Most of these visits are day hikers but there is also the occasional through hiker. Inevitably, these visitors take photos or videos and share them in some capacity with family, friends, and the internet in general. For some this is the closest they may get to experiencing the trail for themselves due to physical li...
