A few recent Mushrooms...

A few young chanterelles. These were the best I found. The only bigger ones tougher, and worm-eaten. Saw many more that were too far gone for me to even think about picking. Note to self: go earlier next year.





I saw a bunch of these. I haven't looked them up yet. There were more than I had seen before.



The final haul. It was rather pitiful. I went ahead and grabbed the few young puffballs to add a little to what I had to cook.

Rosebay Rhododendron on Mill Creek



Rhododendron "(from the Greek: rhodos, "rose", and dendron, "tree") is a genus of flowering plants in the family Ericaceae. It is a large genus with over 1000 species and most have showy flower displays..."

Rhododendron maximum, also called Great Rhododendron, Great Laurel, Rose Bay, American Rhododendron or Big Rhododendron, is a species of Rhododendron native to eastern North America, from Nova Scotia south to northern Alabama.

Approximately 12,000 square kilometers in the southern Appalachians are occupied by this species (Dobbs 1995) where it dominates the understory. This species has historically been confined to riparian areas and other mesic sites but takes advantage of disturbed areas where it is present to advance onto sub-mesic sites.

It prefers deep well-drained acid soils high in organic matter where it produces a thick, peat-like humus. It prefers low to medium light conditions for optimum carbon gain, and has a tremendous capacity for avoiding cavitation during freeze-thaw cycles (Lipp and Nilsen 1997).

Where extensive overstory mortality has eliminated most of the overstory, this species forms a thick and continuous subcanopy known locally as ‘laurel slicks’ or ‘laurel hells’. Rosebay rhododendron is an important structural and functional component of southern Appalachian forest ecosystems.

What isn’t clear is whether or not we are in a period of advancement or retreat for this species. For example, on poorly drained sites on ridge or upper slope positions, large areas of rosebay rhododendron, particularly at the high elevations, have recently died out presumably due to the phytophthora fugus, or due to recent prolonged periods of below-average precipitation.


A few definitions:

riparian A riparian zone is the interface between land and a stream. Plant communities along the river margins are called riparian vegetation, characterized by hydrophilic plants.

mesic "in ecology, a mesic habitat is a type of habitat with a moderate or well-balanced supply of moisture, i.e. a mesic forest, a temperate hardwood forest, or dry-mesic prairie. The opposite of mesic is xeric.

cavitation occurs in the xylem (transport tissue) of vascular plants when the water potential becomes so great that dissolved air within the water expands to fill the plant cell
phytophthora (from Greek phytón, “plant” and phthorá, “destruction, destruction”; “the plant-destroyer”) is a genus of plant-damaging Protists of the Oomycetes (water molds).

Rocky Fork Information (video)

David Ramsey talks about the potential of the 10,000 acre Rocky Fork track. The "number one land acquisition priority of the U.S. Forest Service in the entire United States" and "the largest remaining unprotected tract of land left in the Eastern United States".
