The cOOent rage conditions are explaied under the environmenta baseline section above.
Thus they are not repeated here. Field observations in 1999 indicated range conditions were
poor to fair and were decling (Forest Service 1999). We agree with the Forei;t Service's
conclusion that a downward trend in range condition can be expected from the curent grazg
pressue (Forest Service 2002). We believe their data

The effects of heavy grazng ha reduced herbaceous cover and grass/forb herbaceous ground

effects on MSO prey habitat.
. The BA states that when forage utilzation of35 percent is met on the sumer range, it will provide adequate herbaceous habitat for prey species. The BA also indicates that in meadow

for the followig reasons. First, the Recovery Plan proVides diection for grazg mangement

the MSO. We believe
the curent proposal to establish forage/rage gudelines is consistent with the Recovery Plan and . Forest Plan Anendments, when the stadards and guidelines are implemented and enforced in all
protected and restcted MSO habitat. The Recovery Plan and Forest Plan Amendments reiterate
tht forage/range stadads and guidelines wil expedite attining and maintaining good to of the proposed forage/range conditions. We acknowledge tht attainment excellent rage guidelines may not be possible every year of the permit (e.g.~ see discussion below); however,
over the span of 10 years, we anticipate that the forage/rage guidelines will improve the overall
rage conditions and a,dverse afects to MSO will be reduced.
As noted above, we understad that during some years, the forage/range guidelines may not be will administer the Sacramento
attined. Neverteless, we expect tht the Forest Service
Allotment permt consistent with the Lincoln National Forest Plan, which includes maintanig
the proposed herbaceous ground cover height and forage utilzation, even durng drought conditions. We reached this conclusion based upon the following analyses in the DEIS: 1) allowable uSe guidelines (Le., forage/range guidelines) would require that cattle be moved when the
forage is not sufcient to protect riparan and aquatic system&; i) durg dr periods
allowabie use guidelines (Le., forage/range guidelines) must be followed or the effects from the proposed action would be identical to curent conditions (e.g., overutilization offorage) and not
adhere to the Lincoln National Forest Plan; 3) the variable stocking nite in the permit reflects that
durng dr periods livestock numbers can be reduced when required to meet forage/range
guidelines (Forest Service 2002); and 4) the Forest Service intends to manage and protect longterm range conditions consistent with their range management regulations (e.g., see 36 CFR 222)
We agree with the Forest Service's conclusions in the DEIS that the proposed action will re~ult in a gradual improvement of rage conditions; We expect that MSO prey habitat wil be
maintaed and improved over the life of strve to
the 10-year permit, and that the Forest Service will meet their forage(range guidelines. As provided in 40 CFR 402.16, reinitiation of

Information is available for the Hubble ard Bluf Springs P ACs that indicate forage/range

They believe that such decreases in 1he number of voles could negatively infuence MSO in several recovery unts, are used as alternative food sources when other prey aredimInshed.

It is important to note that Ward (2001) found that grass-forb stubble height had a strong positive Mexican voles and long-tailed voles, two species commonly consumed by MSO in the Sacramento Mountains. .He indicated that voles require herbaceous vegetation for food and cover (e.g., see also Birney et al. 1976; Johnson 1981), and maxmum grass-forb stubble height was a threshold, above which Mexican vole abundance increased with increasing height of both grasses and forbs durng

6.4 in. Beyond this upper threshold rage, increased stubble height of grasses and forbs would .

voles is expected to be diminished as stubble height increases above this rang.e) (Ward et al. In . . prep.). Ward (2001) also found that increasing grass-forb height was positively associated with population abuidance of deer mice. All three species (i.e., Mexican voles, long-tailed voles, and
deer
mice) depend on sufficient grass-forb height to provide for food and/or cover (Johnson
1981; Davis and Schmidly 1994, Ward 2001). On average, no Mexican or long-tailed voles would be expected to occur in key grazing areas when grass-forb height is below 1.6 in, but 4.5 both voles species (Ward 2001). In fact, one method frequently recommended by Cooperative Extension wildlife specialists to

indicated that adaptive management could be used for the puroses of resource protection when monitorig indicates that forage/range guidelines are not being met (L.

Although Attchment A provides some information related to monitoring, additional detals relat~d to monitoring and subsequent management actions are vague in the BA
and DEIS. For example, the Lincoln National Forest did not indicate how the monitoring data

The curent proposal establishes a monitoring-management theshold based on a 4-in herbaceous ground cover height not being met or maintained in key areas (Le., when monitorig demonstrates that the 4-in herbaceous ground cover height has not been maintained in key areas in the pastue, management adjustments will be made so that forage/range guidelines wil be
attined). Based on ths scenario, adjustments wil be made when non-compliance occurs in key
areas withn a pastue. Excessive forage utilzation has been a continual concern on the
Sacramento Allotment since 1991 (Forest Service 2002). Present management is not consistent the Lincoln National Forest Plan (Forest Service 2002). Currently, riparan conditions on the allotment do not meet Regional Plan criteria, the ecological conditionofthe range is nofsatisfactory, and many key areas have not met or maintained leaf . lengt herbaceous ground cover height or utilzation guidelines (Forest Service 2000d, 2001, 2002, 2002b, 2002c, 2003a, 2003b, 2003c, 2003d).Curent rage conditions do not meet the

. Interdependent and Interrelated Actions
We also must consider indirect effects and the effects of interdependent and interrelated actions this proposed project to the MSO. Indirect effects arethose.that are caused by, or result from, the proposed action, and are later in time, but are reasonably certn to occur. Interrelated actions larger action, and are dependent on the larger action for their justification. Interdependent actions are actions that have no independent utilty apar from the
of are actions that are par of a
action under consideration. The livestock projects, including exclosures, livestock trps, and the
use of salt blocks and other livestock management activities (e.g,. vehicle use) are interrelated and interdependent with the implementation of the proposed p'roject. Many of
considered these
activities relate to grazing criteria number 1, which applies to limiting disturbances to MSO
P ACs durg the breeding season. . .
.. The proposed 70 percent forage utilzation stadard for the livestock traps is double what is being. proposed across the allotment. The significance of forage utilzation (e.g., currently
measured using leaflength) guidelines, monitoring, and their relationship to range health and
production are described in the 2003 annual operating instrctions; leaf length has been used as the metrc to describe the lower threshold to avoid damage and possible mortlity to individual the
forage plants The Forest Service documented in 2001 and 2002 that over 50 percent of
monitored key areas had leaf lengths at the end of the grazng season that exceeded establÎshed
guidelines, indicating over-use and the potential for resource daage. They concluded that the
combination of extreme forage use and drought conditions resulted in significant reductions in
forage production across the allotment. Neverteless, the proposed action is for livestock use to occur within traps durng pasture moves in early spring, mid;.sumer, and late fall. The Forest

Trampling
Trapling of individual poppies is unavoidable when livestock graz in occupied habitat. The BA states that light traipling of adult plants is not likely to kill them, as they have a substatial
underground root mass. Neverteless, damage to poppies periods of
from trpling could occur during
low forage availabilty, and could have significant impacts on futue poppy
recruitment. For example, seedling poppies are most vulnerable to mortity while they are in
the process of establishing a taproot Trapling. of fragile seedlings could easily cause the loss .ofindividuas. In addition, grazing may affectriparan vegetation and indirectly result in daage to poppies from lack of soil moistue retention abilty.
It is believed that poppies germinate as early as Februar at lower elevations (Forest Service
1989).. In the first 2 year of
the permt, the absence oflivestock durng late spring and sumer
wil allow vulnerable seedlings and young plants that may be present to put on growt and root
storage, paricularly durng sumer rains, without damage. Removal of livestock prior to the . poppy seedlings as they develop their taproot. emergence of seedlings will avoid impacts to
After the first two winter grazng seasons, seedlings may be utilzed by livestock and mortlity

numbers accordingly, to reduce or avoid adverse effects to

At a tie of low population levels, low seed production, and. drought conditions, the
estblishment of new plants is criticà. Heightened concern exist for diect and indirect effects of livestock grg on germation habitat and seedlings. Seedlings are especially vunerable to
daage by trpling. Seedlings are most likely to germnate and succeed in moister sites in
swales on low benches that also support grses and forbs that green up early in the spring and
attct livestock, rasing the possibilty for hoof damage to young. poppy plants~ Livestock use
in riparan areas, and of riparan shade, creates physical distubances and alteration of habitat
needed to support the vuhierable seedling life stage
of the species. Rest from liye~tock use
durng the fist two years of the permt may allow the poppy some abilty to respond with
recrutment of adults into the population. In futue years, the success of seedling estblishment will depend on good management of livestock withn the pastues and adequate the permit, livestock use in Alamo Pastue will be

Indirect effects-plant community chanl!es
Because of the preponderace of heavy forest, dense woodland, steep slopes, and rock and cliff,
only about 29,000 ac of
the allotment are usable for grazng. Livestock grng would afect the
vegetation on the approximate 29,000 ac usable by livestock. Out of
the approximately 11,000 ac on the Alamo winter pase, only about 3,000 ac are usable. Improper stocking rates wil result in negative impacts to the existing upland and riparian plant communties. Livestock
grazng can afect vegetation species composition, plant density, and plant vigor (Forest Service
2003a). Recruitment of seedlings into the adult population is also afected by any actions that

Concern ha been expressed in the varous sources cited above for the loss of plants due to flash
floods in the canyons; parcularly in Alamo Canyon (Servce 1987). . However, rebounds in the
number of poppy plants have ben observed in year subsequent to daagig floods. Poppy ha been lightly nicked (Sivinki are believed to receive ths mechancal scacation though tubling
see show. the highest germtion rates when the see coat 1992). In the wild, seeds
along a stream bed with water flows.- Flash floods ffayprovide the distbances that f~ciltate
prepartion of a seedbed ard seed scarfication in natual systems. The damaging effects from
flash floods can be exacerbated, however, by chages in vegetative composition and cover in
riparan zones, parcularly in those canyons whete livestock grg has reduced many of the
grses and elimnated many forbs. Significant changes in flood frquency or intensity may not allow poppy populations to recover and re-establish between flood events.
The amount and duration of livestock use plays a significan role in vegetation composition in
th riparan bottoms. As stated in the BA, repeated use of new photosynthetic tissue produced
durg the sprig drought period puts a strn on roots and reduces energy storage abilty for
forage plants that
can eventully afect plant communty composition, riparan health, soil
stbilty and water-holding capacity. Overutilzation of forage has been occurng on the
Sacramento Allotment since 1991, and curent livestock use has resulted in adverse afects to the
poppy (Forest Service 2003a). Any impacts to the plant community that result in decreased
abilty for poppies to withtad and recover from flooding will have significant and long-term
effects on poppy sustaabilty and recovery.
The poppy has shown relatively wide fluctutions in the number of adult plants though the
year. It ha shown the abilty, at leas in years of normal or above normal rainfall, to maintain
. stable populations or recover. A certn level of distubance is therefore believed to be needed
for the species. Biological concerns relate more to indirect effects in the canyons at a time when the number of adults is fewer, and when the seed ban in the soil could be reduced. Curently,
adult plants appear tobe at their lowest numbers~
Indirect effects-population viabilty
Poppy populations in Alamo and Caballero Canyons decreased by approximately 43 percent the poppy decreased from 10 canyons to 5
between 1987 and 2003. Additionally, distrbution of
(Forest Service 2003a). Durg periods of low plant numbers of plants, the combination of several theats occurg concurently becomes more significant. Small population sizes are of concern because of decreaed opportities for out-crossing, resulting in in-breeding that may
lead to higher possibilties for
the fixation and expression of adverse genetic mutations. Lower levels of out-crossing also result in lower frt set and seed production (Tepedino 1992). Periods
of
prolonged drought may result in geraination without establishment, depleting the seed ban
in the soiL. Adult plants may die without sùccessfully replacing themselves if drought periods
extend longer than their approximately 7 to 9-year lifespan. Monitoring observations in 2001
indicate that seedling establishment may bea critical, or bottleneck stage in the life cycle of ths
species (Guaderrama and Barker 2001).

TheForest Service has documented placement of
habitat as the result of minera placement and water development will impact poppies though increased trampling and herbivory.
Other potential actions include fenc.e and water development maintenance. These actions may
result in short term impacts to poppies if constrction activities occur in occupied habitat while
poppies are present.
The Mule Pasture has not been grazd for the last several seasons because there are curently no
fuctionig water sources (Forest Service 2003a). The Service believes that maintenance and
restoration of water sources on the Mule Pastue would reduce some of
the use on the Alamo
Pastue by allowing use of the Mule Pastue containing 2,826 ac of livestock-useable land,

water. Additionally the Mule Pastue is sitUated in Restoring waters here would allow shorter and/or which curently receives increased forage utilzation and
impacts to the poppy.
The recovery rate for a species is considered to be the time needed for populations to retur to
equilibrium after distubance. For individual poppy plants, recovery may be considered to be
the time needed to produce a matue, seed-producing adult from seed. This period is believed to
be two years at minimum, given sufcient rainfall, but could be three years in times of moistue
stress. Impacts to seedlings from the proposed action may occur thoughout the 1 O-year period
of
the permt. This yearly impact could hamper the poppy's abilty to recover from year to year, paricularly at a time of low population levels. In the short term, direct effects on seedlings and recrutment in the spring are of immediate concern. Indirect effects on the riparan plant communty, vegetative cover, soil moistue-retention abilty, and soil stabilty as it relates to
destction from flash floods, are of concern in
the long term.

from livestock use and trplig.
The suer pastues and thstle oCcurnces in the upper Rio Peñaco, including those in
exclosures, are subject to entr by livestock drfting from the witer unt well before the tu-on May 15. It ha been diffcult to keep exclosure fences intat for varous reasons. The
date of thstle is curently found with two of
the trps used to gather livestock. Newexclosures in
Wils and PeñascolWater Canyon will exclude more of the thstle plants, but. some plants will still be subject to livestock impaCts in the Peñasco trp.
Monitorig of the thstle has shown a simple and direct relationship between water availabilty in
suitable habitat and numbers and extent of plants in occurences (Forest Service 2003a). As
water flow.has been observed to decline at sprigs, decreases in plant numbers and the size of
the
sites have occured. The sitution reverses when increased water is available.
With the sumer pastues, the majority of sites providing water for livestock are the natual streams dry up, livestock are forced to sprigs and streams. Durng drought conditions when seek springs for water which puts them more frequently in occupied thistle habitat. Concern
exist at these sites for both trverte and soft-substrate habitats because of impacts created by
livestock use. As stated in the BA, compaction and down-cutting of soft-substrate streambeds
and bans cause water tables to lower resulting in drer sites that may not be suitable for thistles.
Damage to travertine in hard-substraÜ6 sites causes pulverization of the calcium carbonate and
alteration of seedbed chaacteristics for the thistle, thus affecting suitabilty of habitat. Durg supply, impacts at springs can be parcularly heavy. Early drft of livestock onto sumer pastues contributes to impacts. Penods of drought in the fall when the thistle appears to be especially palatable also increase the . likelihood of impacts to individual plants and their habitat.

Indirect effects-population viabilty
To the extent that herbivory, trpling, or hapitat degradation may reduce the density of plants,
seedlings are more exposed to adverse temperatues. . Reduced thstle density also puts the thistle. at a disadvantage in competition with invading weeds such as teasel (Huenneke and Thomson 1995). Thstles in traps will also experience higher levels of competition with weeds and seedling recruitment may be reduced as a result of this competition.
As described in the 1994 Fore.st Service Monitoring Report, small thistle sites may be more
vunerable and at higher risk from the impacts of grazg. To the extent
that growth, vigor,
reproductive output and recrutment are afected by impacts to plants and th~ir habitats, small
sites are of special concern. Expanion at these sites can be affected.by the impacts to habitat
described above, as well as by the loss of seedlings. The abilty to attact pollnators relates
directly to the size of

Afer reviewing the curent statu of the poppy, the environmenta baseline for the action area,
the effects of proposed livestock grang on the Sacramento Allotment and the cumulative
effects, it is our biological opinion that the project, as proposed, is not likely to jeopardize the . the poppy. Critical habitat for ths species has not been designated; thus continued existence of none will be affected. We make this finding for the following reasons:
1. The proposed forage/range guidelines, monitoring and enforcement, development of an
AMP, reduced stocking levels, and deferred-rotation strategy will allow overall range conditions to improve over the i O-years considered in ths consultation.
2. The removal of livestock from the Alamo Pastue, where the majority of known
poppies exist, by Februar i will allow for germination and growth of seedlings without
the theat of trampling or herbivory. Also, this management action will reduce
herbivory and trampling of poppies for much ofthe year. After the first two years,
monitoring of livestock effects to poppies is expected to guide management such that negative impacts. resulting from any documented trampling or herbivory of seedlings
will be elimnated or minimized through managem~nt changes.
3. We anticipate that when the Forest Service determines tht impacts are occuring to the poppy as the result of livestock grazng, they will manage and protect poppy
