Hello, Sbpollock, and welcome to Wikipedia! My name is Ian and I work with the Wiki Education Foundation; I help support students who are editing as part of a class assignment.
I hope you enjoy editing here. If you haven't already done so, please check out the student training library, which introduces you to editing and Wikipedia's core principles. You may also want to check out the Teahouse, a community of Wikipedia editors dedicated to helping new users. Below are some resources to help you get started editing.
Your additions to the The Trust for Public Land article include passages copied verbatim or nearly verbatim from their website. This was detected by automatic plagiarism detection software. For copyright reasons, your entire contribution was deleted. Please review the Plagiarism and Copyright training module before proceeding further.
Also keep in mind that Wikipedia articles are supposed to be written using sources written by independent third parties. You shouldn't use the Trust's own website as a source - it isn't an independent source. You also cannot use phrases like『We’ve helped pass more than 527 ballot measures』- the "we" in that sentence appears to be Wikipedia, which is deeply misleading.

One other item Sbpollock, if indeed you were the one making the changes on The Trust for Public Land's Wiki article -- all the edits were done via an IP address, and not you (unless you did them without being logged on). Mentioning this in part as I also teach and use Wikipedia with my students and need to make sure they know this in case this is a requirement of your course.
