Autumn 4

Wandered around the high school campus again on a foggy-dewy morning while my son refereed.  Lots is going on, some new since I was here two weeks ago, and I took over 200 photos in less than two hours.  Don't worry: I DID edit them down, a little!

 Things fall apart....

..but there can be beauty in decay and death
Red maple (Acer rubrum) can be the brightest of fall trees, but they vary tremendously. 

 The progression by which leaves change varies.
This European buckthorn has red veins, and red around a wound.

Here, I think, is a little scarlet oak (Quercus coccinea) living up to its name.

Black cherry is one of the earliest trees to leaf out in spring, 
but doesn't really get going turning until now.


Tupelo (Nyssa sylvatica) puts on a vivid display, with all its anthocyanin.
It is the brightest of the trees in the lowest image.

This is either flowering dogwood (Cornus florida), or a close relative.

Staghorn sumac (Rhus tomentosa).

 Virginia creeper (Parthenocissus quinquefolia) is a native vine 
that begins turning a little early, attracting migrating birds to its fatty berries.
Alas, this vine lies: the berries are low-quality rose hips of neighboring multiflora rose.

 From one side the leaf shines in the morning sun,
from the other side it glows.

 Oriental bittersweet (Celastrus orbiculatus) is a noxious alien vine 
that nevertheless puts on a display in fall, as the yellow exterior of the fruit 
peels back to uncover the bright red interior, which birds gobble up.

Bullbriar turns a soft yellow that gives no hint of the harm its stout thorns do
to any who wade through it.

 Silverberry (Eleagnus umbellata) is an alien, but still a favorite of mine:
its leaves and fruit are covered with tiny umbrella-tipped hairs that give the entire plant
a silvery sheet.  Its leaves turn yellow before they fall.


Some plants linger to photosynthesize a little longer.  Here are gray birch
(Betula populifolia), elderberry (Sambucus canadensis), speckled alder 
(Alnus racemosa), multiflora rose (Rosa multiflora) and the alien invasive
European buckthorn (Rhamnus frangula).


Not only are some plants still green, a few are even in flower.
Besides the buckthorn immediately above, a lot of weedy little
Aster vimineus (peeking between deer tongue leaves) 
are still blooming, as well as scattered rough goldenrod
(Solidago rugosa) and the odd chicory (Chicorium intybus).

The stream and pond wwere my last stops.  Colored leaves
drifting downstream dress-up even an urban brook like this one.  

Some aliens are obvious in their disregard of seaons.

A good camera angle obscures the fact that this pond lies close between
a large parking lot and the high school football stadium.

Both mallards and Canada geese call the pond home.  
Overhead, a honking flock of geese head southward.

Autumn 2

No calendar-worthy photos, just the nature around the high school where my son was refereeing soccer last Saturday.

Red maple (Acer rubrum) tends to mix its reds with remaining green.
 
 

Some relative of dogwood (Cornus) with blue fruit.

Staghorn sumac (Rhus tomentosa) is a large shrub/small tree with fuzzy stems and large, many-parted leaves.
 


Virginia creeper (Parthenocissus quinquefolia) is a pretty vine
that is even more striking when it turns.


The quaking aspen (Populus tremuloides) nearby had a few leaves turning,
but this gave a distinct yellow cast to trees in the distance.


Speckled alder (Alnus rugosa) basically turns brown in fall.
It's a valuable small tree though, because it has root nodules in which bacteria live
and "fix" atmospheric nitrogen for the plant.  This ends up enriching the soil.
The catkins that will bloom next spring are already present.


Japanese knotweed (Polygonum cuspidatum) is a serious alien invasive.
It produces enormous numbers of offspring, and it's all over the place.


Poison ivy (Toxicodendron radicans), a good, card-carrying native,is mainly invasive
(not to mention annoying) because it is our shadow: it like the habitat "edges"
we create when we clear, build, etc.  But at least it's pretty in the fall!

At the pond edge, cattail (Typha latifolia) leaves are beginning
to die, but leaving their iconic fruits.


Just now in bloom, this aster seems a little incongruous.

Taking the large view, you can see that there's still a lot of color ahead.
