Question 1

How many acres per timber sale will require marking? What is the retention percentage specified in the prescriptions (e.g., 20% retention)?

Answer:

500 acres of individual Tree Mark. See updated table.

More detailed prescriptions will be provided after Contract is awarded.

Question 2

How many skips and gaps will be designated, and what is their typical size?

Answer:

There are 35 skips totaling 68 acres. Most Skips act as dropped areas from Planning Unit. Skips that are adjacent to the boundary will be marked as Boundary. There is only one skip that will need to be marked as Skip separate from Boundary in 25-9 Scholfield Unit 2. It is 0.6 acres.

There are 64 total Gaps, only in Restoration Thinning Units. One center tree is marked with either Yellow or White paint depending on if it is a cut center tree or leave center tree prescription. 51 Cut Trees and 13 Leave Tree Gaps.

See updated table.

Question 3

DSL indicated that the contractor is responsible for orange and black paint — is it correct that DSL will supply all other paint, flagging, and tags?

Answer:

Yes.

Question 4

In the marking specifications for “Designate beginning and end points of ELZs,” it states, “If directed, Equipment Limitation Zones will be marked.” Should the proposal assume that all mapped ELZs on the project maps will be marked?
