Re: stipulation Nc. 5 (Shrub Density Standard} File hlo. C-Ol9-dlv
Dear Idr. 1Ciaer
You have proposed a woody plant density standard of 85G stems per acre for the
Coiowyo (dine. Further, you have proposes that a minimum of 26fo of the
reclaimed slopes less than 5:1 would be designated shruo clump establishment
areas wnere transpranting of mature shrub clumps ono/or direct seeding and
transplanting of shrub seedlings would be employee. Ptesures to enhance
estaolishment of seeding shrubs in the shrub c]ump estaalishment areas will
include the use of direct haul topsoil and/or a moaification of the regular
herbaceous seed mix (so as to reduce the coRyetitien between herbaceous
• species and seedling shrubs).
-he Division has two remaining concerns. First, as you have observed, a
standard of 1,006 woody sterns per acre has been reccncnended by the Division of
Wildlife for reclaimed lands in Northwest Colorado. Given the scmewhat
generalized nature of the shrub estaolisnment clan provided by Coiowyo and th_
lack of specific justification fnr the propose. 850 stem per acre stem density
• standard, the Division does not feel comforta:,:e in approving a woody density
stanaard which is lower than that recemrer.dec by the 7ivision of Wildlife.
Second, the plan indicates t.tct in some instances the regular seedmix will not
b= seeded in order to re•nuce herb aceeus competitien. The Divisidn agrees that
as alternative seed mix is warrantee. Fnformation should be submitted on the
~noaified seed mix ana seeding rate and the criteria which will ne applied in
selecting areas which would not be seeded with the regular seed mix {acreaa?,
slope, erosion control etc.}.
In resolution of Stipulation ~o. 5, the Division sets the woody plant density
standard r"or the Coiowyo ?Ifne at 1000 stews per acre for ail portions of the
reclaimed area exceRt perimeter slopes which are steeper than 5:1.
Shrub reestablisYlment is to be acccr~lished as specified in this letter ana
your letters of November 8, 1983 antl October 25, 1960 (with ;he exception
_ being the objective of LOCO stems per acre rather titian 856 stems per acre;. a
:~;ity standard rril7 not be applie•~ {:o the ;eriireter slopes steeper tl:ar. 5:1
