Estimates of Grazing and Erosion

Notes Grazing is 4 in watershed, but 2 near stream. Site is covered by seeps of tannic acid, a sping, ponds, effluent, and a stream. Great site. Horses, cattle and sheep went through seep areas to drink(?). Some grazing but good habitat still above ridge (outside stream/seep spring channel). Heavy grazing. Several gers, sheep, cattle, yaks, goats, but stream looks good.  Large green male found in tall grass far from stream. New roads above some runoff, logging above Alpine stream w/some herds of yaks and horses above site. Rocky, high gradient stream. Hard to tell the difference b/t grazing erosion and alpine hard scrable. Herdspeople said their montane valley has changed in the last 10-20 years. Birch has disappeared and stream has dried in places. Park like with trees (Populus salix) and grasses and forbs. We collected along a small, meandering braid with nice riffle, run, pool sequences and good riparian habitat. Site appears relatively unmodified. It is composed of rocky (volcanic) substrate and marshy areas and seeps. Yaks, goats everywhere! Series of pools connected by small stream. Sandy bottom stream with shrubs, some new growth larch stands. Grazed but not too mcuh recent grazing. Drier climate, more dryland plants.
NA=Not Applicable
ND=No Data
* Code = Selenge River Project (SRP) followed by two digits for year, two digits for month and two digits for day and two digits for site number sequence for that day.
**Grazing Codes: 0=no grazing evident; 1=slight grazing; 2=moderate grazing; 3=heavy/mixed grazing; 4=heavy grazing.
***Erosion in Watershed Codes: 0=no erosion evident; 1=slight erosion; 2=moderate erosion; 3=heavy/mixed erosion; 4=heavy erosion.
****Erosion in Stream Channel Codes: 0=no erosion evident; 1=slight erosion; 2=moderate erosion; 3=heavy/mixed erosion; 4=heavy erosion.
