SPECIFICATIONS– All boundaries and/or corners are marked with black and orange striped flagging and orange tags or blue flags and blue tags.

*Some of the units have large areas that don’t have trees. These areas, expressed as percent, shall be within the unit boundary but no work shall be needed there. Approximate number of trees per acre are for treed acres and don’t include these areas.

** All stem densities are an estimated average over units that vary from dense thickets to openings that don’t need treatment. The offeror is advised to visit the work sites to determine average cut trees per acre prior to submitting an offer. The offeror is responsible for determining the amount of work.

Species abbreviations are as follows: DF = Douglas-fir, ES = Englemann Spruce, LPP = Lodgepole Pine, PP = Ponderosa Pine, SAF = Sub-Alpine Fir, WL = Western Larch, WRC = Western Red Cedar.

1/ For All Units

· Cut trees shall be 6.9 inches in DBH and smaller UNLESS OTHERWISE NOTED. All trees not intended for leave trees, larger than 1 foot in height shall be cut. No trees 7”DBH and larger shall be cut.

· No hardwoods shall be cut, unless otherwise specified.

· No cutting shall occur within 15 feet on either side of stream beds, springs or marshy areas (or further if specified).

· No tree shall be left hung up in another tree.

· Stump height shall not exceed 6 inches.

· Slash shall be lopped and scattered unless piling is prescribed. Slash depth shall not exceed 2 feet.

· Pullback slash 5 feet from forest boundaries, hand and machine fire lines, developed springs, troughs, fences or other structures and trees greater than 16 inches in DBH.

· All trees less than the maximum cutting size (see chart) shall be removed for a distance of 25 feet from trees greater than 7 inches in DBH.

2/ For units where spacing is used rather than whipfalling only:

· Space off all trees 7.0 inches in DBH for 25 feet before leaving a leave tree. Smaller trees shall be left at the spacing indicated in the chart.

· Leave trees shall be the biggest and most vigorous, with best crown ratios and without signs of insect, disease or other damage. Do not select leave trees with signs of dwarf mistletoe, root rot, bark beetles, mechanical damage, flat tops or other signs of poor vigor.

· Where tree vigor and size are equal within a 1” size class, species preference is as follows: PP, WL, DF, ES, AF, LPP and WRC (unless otherwise stated).

· Shall not cut any trees marked in orange.

3/ Vegetative screening cover (irregular clumps of small trees and brush that reduce the viewing distance into the unit) shall be left for 10-20 along the FS road 2114 where it currently exists for a distance of 10-20 feet on each side of the road. This is to reduce the ability to spot wildlife from the road and to improve visual quality.

4/ No cutting shall occur within 50 feet of the stream.

5/ Leave (don’t cut) ponderosa pine and space off them.

6/ Whipfall all DF, LPP, SAF, ES less than minimum size (see chart).

7/ Leave (don’t cut) western larch and space off them.

8/ Whipfall all trees less than the designated DBH (see Max DBH Cut Limit in above chart) unless they are marked with orange paint.

9/ Trees shall be spaced at 22x22, except between the 540 and 550 road where spacing shall be 16x16.

10/ WL and PP over 6 feet tall and under 7” DBHshall be thinned to a 16 foot spacing

11/ Handpile existing natural ground fuel and slash. Pile all of the existing ground fuel that is one inch to 12 inches in diameter. Pile size shall not exceed 6x6x8 feet in size. No pile shall be placed within 8 feet from the bole of any leave tree. For unit F, H, and 26 pile only the northern portion. For unit 46 pile 60% of the slash as stated above, leaving the rest in discontinuous concentrations.

12/ Leave all ponderosa pine. PCT WL to stated spacing.

13/ Unit is behind a gate. Contractor shall notify CO for entry.
