env_field_note:
buried organic horizon 12-13cm suggests that has alternated between fbraf and fboa, presently fbraf; 48-64 cm coarse and gravel;  dead standing alder is larger size class, also tall shrub is lsrger salala and alnten, the buried organic layer likely related to peod of more stability and overbank flooding when shrubs got large, more recently surface is channel deposit and a flooding or ice event led toresetting succession to early willow-alder phase when larger shrubs were killed; dead standing is alnten

This has been happening all over in these floodplains.  Coarser sands and gravelly horizons have too low a water holding capacity to allow for anaerobic soil conditions.  The water table must be elevated in the early growing season and/or frost in the upper fine provides moisture into the system.  From 2-7cm, C hor.

I am reserving the "ds" micro-topo code for the deep incised channels we've seen on the inactive and abandoned overbank surfaces.  These are mini-scour chanels with some ripples on the surface.

Fbop. Plot area is pretty variable & there is a circular more open shrubby area to the west (in middle) so we changed the plot size to 5X10 to take in more of the fbop. I was expecting more of closed-ish popbal pole stand but it is more open. There are a few timber-size popbal in plot but by far most is pole  sapling.

veg_field_note:
5x10 plot. Stoa found alongside a tributary that HDR is mapping. Carutr & equpal border the tributary. The shrub is on the high end of open - there is enough open space for matst to be growing well. Just beside plot,there alot more matstr (6ft tall matstr) - this would go hfmc if the area is big enough to map. Very doubtful that the hfmc is big enough to take out.


veg_field_note:
very similar to T42_05 with exception of picgla absent, and higher popbal cover; dead standing is popbal and alnten


veg_field_note:
odd, even-aged picgla; cabin ruins 100m toward t26_02 maybe explain


veg_field_note:
A lot of dead standing alder. Stow w/ cutpoint of hgmbs. This is a better cutpoint than stoaw. Not much alder. Serious willow browsing in plot & moose beds & moose diarrhea seen.


veg_field_note:
Sloa. Cutpoint hfmc. Here is a case where the general mapable area would he fbwp...but the plot and at least 1 acre seems much more sloa or hfmc. Well site 128_26. 5x10. Some popbal is outside of plot. is some willow but not enough for sloaw.

Sddt - but not tundra. Fix veg call? Nice dryas patch. Larger signature & less shrubby than T09_02. There is less live dryas & more dryas litterhere than at T09_02. Also a lot less bare soil. No obvious signs of recent flooding but some ice rafted rocks & small driftwood.

Fbwp with cutpoint of fbop. Few betpap in plot. Large timber size popbal & betpap.


veg_field_note:
Major tablet issues...see els app for veg notes.

Odd microsites w/ hydrophytic veg;seasonally flooded?


veg_field_note:
Fbop with cutpoint of fmosp. Looking in the distance outside our actual plot, there is more spruce & this would go to Fmosp. Overall, would probably be mapped as Fmosp. A lot of dead standing alder in plot. A fair bit of dead down popbal - not windthrow though.


veg_field_note:
Well 128_4_W1. Fbwp. Located plot about 50m from well. Some of the popbal has broken tops- some kind of wind event maybe? Despite being broken at top, it appears to be growing rather well - in a weird contorted manner.


veg_field_note:
Some windthrow on plot of large timber popbal. Plot flooded this year. All fresh sediment with somepopbal seedlings. Some alder has been mowed down by ice. .


veg_field_note:
Fmcpws. Some dead standing alder in plot. Also some dead down popbal.


veg_field_note:
Lots of balpop saplings - if they grew up this would be heavily forested.

Nice fmosp with thick understory of tall & low shrub. Windthrow on plot of both popbal & picgla. Also, some large dead down popbal on plot.


veg_field_note:
Plot in the tributary. The source of the tributary is most likely a spring. The sedges & grass are quite thick. Veg class is hgw. HDR are mapping this for habitat purposed. We talked with them.

Stoa. 5x10 plot near actual well site (128_3_W1). Needed to do a 5x10 to catch the stoa. We managed to find an area that wasn't too trampled. Just northeast of well site about 10-20m, veg class turns into more of a stca but well is on stoa.

Young cottonwood with some willow, slightly elevated sandy bar deposited recently, few large alnten in area,


veg_field_note:
Lovely dryas dwarf shrub plot. sddt but NOT tundra. Older bear & moose tracks in plot. Both saplings and pole-size popbal in plot. Moss in some parts of plot. Almost all litter is dryas . litter mixed in with live dryas. Soil is very dry. Deposition is only on dryas litter - not fresh leaves...suggesting it only flooded in spring 2013.


veg_field_note:
Fbop. Large timber size popbal. Standing dead alder in plot. Some picgla outside of plot (in looking at a distance) but not enough for a mixed forest call.


veg_field_note:
Fmwsp. Outside the plot there is a fair bit more picgla. Dead standing alder in plot. Picgla is slightly intermediate in height to popbal. 30% mounds in plot - mounds about 1m tall with predominantly rosaci/calcan on them. Cause of mounds ???


veg_field_note:
Veg class Stoa. Cutpoint Hgmbs. Switch this in the els form. Also , a lot of dead standing alder.


veg_field_note:

old tall alnten snags throughout;no scour marks on huge popbal's


veg_field_note:
vegclass4 of sdbt. Most bearberry is 1m tall - not dwarf. Animal haven - def animals disturbance. Bear & moose scat & moose tracks. Outside of plot about 20m there is a lot more lichen (stere) & dryas- maybe reason for white signature on imagery??


veg_field_note:
Similar species as T42_04 but different proportions, higher productivity here due to grpund water differences and more recent floding here as indicated by buried O-horizon near soil surface?


veg_field_note:
Fbcp. Mix of pole & timber in plot but most is pole . size. Fl3ooded in 2013. Some pole size rafted trees laying in plot.


veg_field_note:
Fbop. Fair bit of dead standing alder in plot -about 2%. Some dead down popbal.multiple drainage channels in plot. A lot of calcan in these. Lots of microtopo.

veg_field_note:
needleleaf borderline intermediate with broadleaf dominant

Nice fmosb with very robust, thick and diverse shrub community (mix of tall & low shrub) in understory. The tall alder forms a nice closed strip (nly about 10-20m wide) in the open forested area.


veg_field_note:
Plot paired w/ R2 well site ESGFA128-25; heavy sand deposition spring 2013. Plot in untrampled area 25m N of well site


veg_field_note:
Drainage. Stoaw..high end of open. The clearing south of point T01_03 looks to be stca. Could be stcaw. Not enough time to sample this unfortunately.


veg_field_note:
Active gravelly bar, small patches of are sands and gravel intermixed with more vegetated areas; poplar saplings smaller size class, 0.3-100 cm tall


veg_field_note:
Fobp call. Popbal, picgla & betpap all large timber size. All ribgla on line points should be changed to Ribtri. There is ribgla as a trace in plot though.Moose & bear scat in plot. Lots of animal trails. Not enough picgla for mixed forest call.

veg_field_note:
Looks like old wind disturbance or JJ's pathogen theory?? A lot of old dead standing alder-snapped at top.


veg_field_note:
Thickest willow plot ever. All salix1 hits should be salbar1. Change this.


veg_field_note:
if you counted overlapping hits of matstr you would likely have 310% cover of forms in this plot
