NR1020 Phenology Blog – Gabby Grzan The Phenology of Centennial Woods

Birds-Eye Map of Phenology Spot

The specific spot which I have chosen for this project lies on a bridge above one of the streams running through Centennial Woods. This area is significantly disturbed- being largely overrun by invasive “Common Reed” (Phragmites australis) and in close proximity to other invasive species such as Japanese barberry (Berberis thunbergii) and Alder buckthorn (Frangula alnus). Some of the native species observed in the area are Devil’s beggarticks (Bidens frondosa), Purple loosestrife (Lythrum salicaria), and Reed canary grass (Phalaris arundinacea). In addition to the presence of invasive species, it is clear that this stream deals with a great amount of stormwater runoff from the surrounding area, as there are recurrent collections of oil along the streambank.
