After the seedlings emerge, they are thinned to a spacing of 10 to 12 inches (Cahn 2014; Smith et al.
In 2014, seven sites were established in which half the field was manually thinned and the other half was thinned with an automated thinner (table 1).
At both the thinned and unthinned sites, a thermometer probe (Li-6400 system) was used to measure soil temperature at a depth of 5 cm at the same time as soil respiration measurements were taken.
gmelinii), birch (Betula platyphylla), and ash (Fraxinus mandshurica) was carried out at both the thinned and unthinned sites.
In this study, mean plant density for thinned rows was 68 000 plants/ha, while the mean plant density for non-thinned rows was 78 500 plants/ha with a maximum of 87 700 plants/ha (Table 1).
On first glance, it appears the latter may be the case since hybrid rank (i.e., I through 10) in the thinned and non-thinned treatments were significantly correlated (R = 0.72, P [is greater than] |R| = 0.0186); however, this preliminary conclusion does not stand up to closer scrutiny.
They showed that in the Biscuit fire, 80 to 100 percent of the trees died in forests that had only been thinned
, while 5 percent of the trees died in forests that had been thinned
They have thinned
200 acres of national forest land and implemented three Forest Service thinning contracts in the Ranger District.
The Barrows expect to hire four people and produce 2,500 bags of bedding each day-about 40 cords of wood or between 5 and 15 acres of thinned
The smaller thinned
wood will go for energy production or paper; some of the larger trees will become lumber, some will be holding up telephone lines next year.
