The newest edition of Great Lakes Botanist has an item about two native species newly found in Leelanau County, Michigan. Liana May found horsebalm and highbush blueberry roughly a hundred miles north of their previously known range. Is this global warming at work? The impacts of increasing human activity on plants are a serious concern. But one impact is that more and more of us are out there collecting specimens. Collections like these are often just because of this increased activity. And modern information systems can immediately alert a collector that they've found something of interest. You can look it up on your phone. Highbush blueberry grows in AL, AR, CT, DE, GA, IL(E), IN, KY, LA, MA, MD, ME, MI, MS, NC, NH, NJ, NY, OH, OK(E), PA, RI, SC, TN, TX, VA, VT, WA, WI, WV, BC, NB, NS, ON, and QC(V).
