Be Your Own Brain Advocate: Why Older People Should Request Routine Cognitive Testing, Josey M. Batura, Elizabeth B. Fauth

All Current Publications

Your primary care physician can conduct regular screenings and track cognitive changes; however, patients may need to advocate for and request testing. If there is noticeable loss in cognitive function, you may benefit from a more accurate diagnosis and a treatment plan or care plan from a medical specialist. Detecting cognitive changes early is better than knowing too late.

Reeds Run Amok: A Practical Guide To Managing Phragmites-Invaded Wetlands, Christine Rohal, Keith Hambrecht, Chad Cranney, Karin M. Kettenring

All Current Publications

Phragmites australis (common reed or simply “phragmites”) is a tall-statured, highly productive wetland grass. It spreads rapidly, often displacing native plants and degrading critical habitat for shorebirds and waterfowl by reducing the availability of nesting, loafing, and foraging areas. Phragmites also consumes large amounts of water, adding pressure to already scarce water resources. Additionally, the accumulation of standing dead biomass can be a fire hazard. Phragmites makes large areas of wetlands inaccessible to both wildlife and humans. This guide provides guidance on managing phragmites.
