If you're running into these maybe you need to see an eye doctor. In woods near here we wouldn't run into nearly as many native species, only a handful of species in each category (conifers and broad-leaves).

Yesterday I was looking at a sort of revegetation menu at Half Price Books, were it was tagged at nearly 100 dollars - I didn't jump on it. In addition to the comparatively high numbers of tree species listed for areas down your way the Mesophytic Forest of Appalachia was loaded with taxa. The Siskiyou-Klamath region and the southern Appalachians are the analogs to Chinese forests in North America, refuges where numbers of species are concentrated.

I walk around my neighborhood and the local quiet country roads and there are a ton of beautiful conifers planted all over. Many are indigenous(douglas fir, noble fir, hemlock?), but there are also a lot of human planted beauties including serbian spruce, korean firs, atlantic cedars and ginko trees. I feel very lucky to be able to gaze at such beautiful trees on a regular basis. Mature serbian spruce in particular are just stunning. 10' wide and 30' tall with branches all the way down, curving up.

This is James Dean country. You can see that image of the rebel kickin' up dirt as he walks on gravel roads, lighting up his smoke with corn on flat land and valleys and streams winding around but mostly flat. Some folk here would probably rather be in Hollywood, however, not I! I'm way too cool for that;-). Rebel without a cause...

Dax

Lots of Norfolk Island Pines. Some dying (they always look like they're dying to me) and hideous London Plane trees. Tall and skinny coast redwoods. A giant SEquoia or two. Many Canary Island Palms. Monterey Pine. Acacia trees (invasive). Coyote Bush. Eucalyptus trees in the trainyard. A few old coast live oaks. Winos. Cop cars. Yuppies "slumming it" after blowing eighty dollars on sushi.

Moss forms a soft carpet in turf here - a mawn. Carpet of green with no mowing, watering or fertilization.

I have walking trails around my property and I see:

Hey, Pinetree!
I know that we're in a similar environment, so I'll just borrow your list:

Grey (Digger) pine
Incense cedar
Douglas fir

California black oak
Valley oak
Blue oak
Canyon live oak
Interior live oak
Bigleaf maple
California buckeye
Fremont cottonwood
California bay laurel
Madrone

And, of course:
Ailanthus and camphor, which both do quite well.

Josh

Natives behind the house and down the street a little:
In order of numbers
Sugar maple
Wild Black Cherry (Prunus serotina)
Slippery elm
Red oak
Red Maple
Black Locust (robinia pseudoacacia)
some kind of leaf miner is wiping the locust out from any spot where it has any competition. It gets it leaves late in the season and is stripped clean my mid august, so it has a hard time making it.
Sycamore
White ash
Cotton wood
American Beech
Shagbark hickory
Flowering dogwood (cornus florida)
Yellow birch
Black birch
Eastern Red Cedar
White oak

Not as common
Black walnut
Chestnut oak
Butternut
Canadian Hemlock
Paper birch
Canadian yew- the deer have nearly elliminated this one.
Tulip tree
Honey Locust
White Pine

Sometime ago I tried to ID my woods according to the Wisconsin DNR classification of forest communities, but of course the natural environment is not quite that tidy or simple. NORTHERN DRY FOREST probably comes closest to describing it, but it also contains elements of NORTHERN DRY-MESIC and NORTHERN MESIC. We've got a ridge (Tower Ridge) running through the woods, and I've always found it interesting how plant life changes depending on which side of ridge you're on. The slightest difference in soil temps seems to make all the difference.

Here is a link that might be useful: Forest Communities

Hi. Or the exposure. A nursery-friend of ours was saying this about Pinus cembra and P. uncinata. First one grows only on the N. face of a particular mountain,the second one on the S. side. Apparently,the ridge is the dividing line,with no individuals of either sp. found on the 'wrong' side.T.
