A gorgeous fall day

These pictures will make office workers everywhere weep with envy at how sweet it is to be a field biologist. Today I was working along Staten Island's South Shore.
Fall foliage isn't limited to the trees. Here bracken fern (Pteridium aquilinum) glows a golden hue. {Most people think of ferns as dew-covered fronds growing lushly on the rich forest soils in the umbrage of canopy trees. Bracken fern laughs in the face of convention. It is a sunshine-embracing, sandy soil inhabiting fern. It is adapted to fire, with its root stock (rhizomes) nestled deep in the earth to avoid the flames. It's also quite common - keep an eye out for it the next time you are in the pine barrens or on Staten Island in Conference House Park or Clay Pit State Park Preserve.}

Here you can see clearly the glacial till sandy soils. The vegetation - trees - gray birch (Betula populifolia) and sassafras (Sassafras albidum) and that's a scrub oak to the right. The pine is short-leaf pine (Pinus echinatus). The shrubs are black chokeberry (Photinia melanocarpa) or if you are old school (Aronia melanocarpa) and the gorgeous reds in the background are highbush blueberry (Vaccinium corymbosum). The cloud-like white puffs are narrow-leaved boneset (Eupatorium hyssopifolium var. laciniatum), a New York State rare plant.
