DISCLIME
Recovery plans delineate reasonable actions that are believed to be required to recover and/or protect listed species. Plans are published by the u.s. Fish and Wildlife Service, sometimes prepared with the assistance of recovery teams, contractors, state agencies, and others. Objectives will be attained and necessary funds made available subject to budgetary and other constraints affecting the parties involved, as well as represent the need
to address other priorities. Recovery plans do not necessarily
the views nor the official positions or approval of any individuals or agencies involved in the plan formulation, other than the u.S. Fish. and
Wildlife Service. They represent the official position of the U.S. Fish
and Wildlife Service only after they have been signed by the Regional Director or Director as approved. Approved recovery plans are subject to modification as dictated by new findings, changes in species' status, and completion of recovery tasks.

Brief Overview
The sacramento, Mountains thistle (Cirsium vinaceum Wooton & Standley) was listed as a threatened species under the Endangered Species Act of 1973 (Act), as amended, on June 16, 1987 (U.S. Fish and Wildlife Service 1987). This plant is known only from the Sacramento Mountains of south-central New Mexico. It was originally discovered in 1899 by E. o. Wooton near Fresnal,
New Mexico. The population ,at the type locality has since been extirpated
by agricultural activities. The remaining populations are mostly on the Lincoln National Forest in mixed conifer/mountain meadow associations. irrigated areas associated with They always occur in wetlands or sub springs, streams, and seeps. The Sacramento Mountains thistle is threatened by water diversion at spring habitats, direct and indirect
~pacts from 'grazing, competition with exotic plant species, logging, and
recreation. The recovery priority numer for Sacramento Mountains thistle numbers range from 1 to 18, with species ranking 1 is 2. Recovery priority having the highest recovery priority.
Taxonomv
The type specimen for Cirsium vinaceum is in the U.S. National Sacramento Mountains near Fresnal" (wooton and Standley 1913). It was originally named Carduus vinaceus in accordance 'that time. Wooton and Standley (1915) later with generic concepts at comined it with the genus Cirsium where it was maintained by Petrak (1917) in his revision of the North American species of Cirsium. Although cirsium is a common genus in the New Mexico flora, Cirsium vinaceum is a distinctive species with no close relatives within its range of occurrence. Its closest relative ,is the Mexican species, Cirsium

The Sacramento Mountains thistle is a stout biennial, 1-1.8 meters (3.3-5.9 feet) tall, with many ascending, brown-purple branches. The basal leaves are green, not hairy, 30-50 centimeters (12-20 inches) long, up to 20 centimeters (8 inches) wide, ragged edged, and divided nearly to the tipped with slender yellow spines. Flowering heads midrib, the divisions are 5 centimeters (2 inches) in diameter and almost as high, numerous at the ends of branches, naked, and bell-shaped; involucral bracts are of several ranks, deep red-purple, bent back at about the middle, and tipped with short yellowish spines. Flowers are pink~purple; the fruits or achenes are obovate, brown, and glabrous, with a tawny plumose pappus 15-20 millimeters (0.6-0.8 inches) long.

Distribution and Abundance
The Sacramento Mountains thistle occurs mostly on u.s. Forest Service (FOrest service) lands of the Lincoln National Forest in the Sacramento Mountains of south-central New Mexico within a range of approximately 150 square miles or four townships (Figure 1). There are occupied habitats on private and Mescalero Apache lands in the same general area. However, the Forest Service is the principal land management agency within the range of this species.
When the U.S. Fish and Wildlife Service (Service) determined that the Sacramento Mountains thistle was a threatened species (U.S. Fish and Wildlife Service 1987), there were 20 known population areas (within six
that original estimate, 62 sites (mostly subdivisions of the original 20 populations) on a total of 77 acres of suitable habitat have been documented by the Service (U.S. Fish and Wildlife Service 1988). Of the 58 sites located on the Lincoln National Forest, the Forest Service estimates at least 49,000 plants grow on a total of 66 acres. Since this plant is capable of adventitious reproduction by root sprouting, the Forest service density estimate of individual plants is derived from the total numer of rosettes divided by four. Therefore, a total of 196,000 rosettes (juvenile and mature) were counted during the 1990 inventory. populations that have been closely monitored appear to be somewhat stable in terms of mortality and recruitment (Thomson and Huenneke 1990a). Three additional sites occur on Mescalero 'Apache land. One site is on private property.

The Sacramento Mountains thistle is a riparian plant that requires and streams. 'These occupied wetlands
are unique in their calcium carbonate content. As the groundwater reaches the surface, the change ,in pressure and temperature precipitates the calcium carbonate onto organic materials. OVer time, large areas of travertine deposits are created at the spring sources that occasionally become large bluffs or hills (up to 0.8 hectares or 2 acres). These
continuously wet travertine deposits are the most comon habitats of the
Sacramento Mountains thistle (Thomson and Huenneke 1990b). Wet areas are often sparsely inhabited by this downstream from these features thistle. A few valley bottoms with wet calcareous soils, such as Scott Able Canyon and Silver springs canyon, are occupied by very large

In fact, spring habitats often support dense monospecific stands of Sacramento Mountains thistle. occupied travertine soils have re1atively high nitrogen and low phosphorus contents (Thomson and Huenneke 1990b).

population BioloQV
scarcely more than 100
Many of the occupied Sacramento Mountains thistle habitat sites are meters (330 feet) apart and are as small as 5 square
meters (54 square feet). Therefore, they cannot be called "populati.ons" in
understanding of what constitutes a
a reproductive or genetic sense of the term. At present, there is no clear population for this species. Pollen vectors include hummingbirds and numerous species of bees, beetles, flies, and moths. The seed is heavy, but fairly dispersible by wind. Therefore, gene flow from pollen vectors and seed dispersal is probably effective up to about 0.5 mile. If this were used as the minimum distance between populations, then approximately 20 populations occur throughout the current range (U.S. Fish and Wildlife Service 1988). Nèvertheless, groups of plants that densely occupy wet travertine deposits are, hereafter referred to as populations in the management sense of the term, since they occur on a unique and identifiable type of habitat.
Travertine substrates at springs and streams are the most densely occupied habitats. There are numerous examples of. scattered plants that
- -
occur~long streams and wet seeps downstream of and between the larger
populations. The, densities of these peripheral plants fluctuate greatly in
response to yearly precipitation and grazing management practices. These scattered individuals may serve as stepping stones in the flow of genes between larger populations on more suitable habitats.
Some morphological and habitat variation between popUlations has been noted. For instance, at the Silver Springs site there is a large group of plants on calcareous soil in the valley bottom rather than on a travertine
outcrop.
Impacts and Threats
The major threat to the Sacramnto Mountains thistle is
,the potential
appropriation and development of water rights directly from spring habitats. At present, the watershed is unadjudicated and the water rights at these springs are available to anyone wanting to appropriate water for a beneficial use. The Forest Service has some control through special use how springs will be developed on the Lincoln National Forest. permits on Water rights can be acquired without threat to Sacramento Mountains thistle is imediately below the spring. spring habitats if the point of diversion
The Forest Service can stipulate this condition in a special use permit for spring development. At present, New Mexico is one of the few states that

does not have an instream-flow statute. Such a statute would allow appropriation of water rights to maintain minimum flows necessary to support biolçgical values. water for fish, wildlife, and other natural considered a beneficial use under resources has not traditionally been current management; however, it may be possible to establish this use of water in the future. Until instream-flow legislation is adopted by the State and water rights are appropriated for Sacramento Mountains thistle, this plant will always be threatened by spring development and loss of
habitat.
Another land use that has been identified as a threat to this thistle ~s graz~ng. The Sacramento Mountains thistle occurs on four grazing allotments on the Lincoln National Forest. Grazing management over the past decade on the allotment with the majority of Sacramento Mountains has required one complete growing season of rest for every summer thistle of grazing use. Hqwever, during seasonal use, little effort in the past was made to distribute cattle grazing either by herding or constructing smaller pastures. The result has been severe grazing impacts to valley plants where livestock were bottoms, riparian areas, and to individual allowed to congregate for 'long periods. In recent years, permittees have made an effort to spend more time herding.
Some Sacramento Mountains thistle habitats, such as Silver springs, which has 'been severely impacted from past trampling and soil compaction, have since been fenced. The Lucas Canyon populations illustrate a drastic reduction in plant rosette size as an apparent result of grazing impacts (Thomson and Huenneke 1990a). In Scott Able Canyon, cattle have been observed eating the flowering stalks of Sacramento Mountains thistle plants, and there were also signs of grazing on the leaves of the rosettes. Cattle have since been herded away from streamside thistles there. Aside damage to the overall vigor of the plant by reducing from grazing causing the number and size of leaves in the rosettes, damage to or loss of a flowering stem before seed set is very detrimental to the growth of thistle populations. Because these plants flower only once, the loss of a stem means the loss of the entire reproductive output of that plant (Laura Huenneke, Biology Department, New Mexico state University, Las Cruces, New Mexico, pers. comm. 1991).
vulnerability to grazing
Each Sacramento Mountains thistle population has its own level of impacts because of the variable topographic
position of occupied habitats. Fortunately, many of the spring habitats occur on large travertine bluffs too steep for frequent access by grazing livestock. Elk tracks have been observed in the thistle populations- on
some of these slopes, indicating that they are contributing to
the
herbivory as well.
other types of potential land use impacts include logging and road building. The Forest Service has a policy of maintaining a 200-foot buffer area around known populations when trails, roads, and logging operations
are planned (U.S. Forest Service 1989). Indirect impacts
from timber

Recreational impacts arè occasionally observed in areas of high The Bluff springs population has been closed'to foot traffic by building a fence around the travertine bluff trails around this feature. The Forest Service has routed alternative foot

population. Other thistle habitats are occasionally impacted by off-road vehicle traffic.
Many of the valley meadows within the range of the Sacramento Mountains thistle have recently become infested with the exotic teasel (Dipsacus svlvestris). Greenhouse competition studies of teasel and the Sacramento Mountains thistle indicate that the fitness of the native thistle is reduced when the stand is invaded by teasel. Results of thistle seeds are unable to germinate germination trials suggest that beneath a closed teasel canopy, but teasel may be able to germinate beneath dense thistle leaves (Thomson and Huenneke 1990c and 1990d). Therefore, there is potential for the thistle to become excluded from some of its drier habitats by the invasive teasel. At present, there is little evidence in the field that the saturated travertine of spring habitats is suitable for teasel invasion. However, there are some wet meadow habitats that do support both thistle and teasel. Therefore, the Serv ice does not have a complete understanding of the ecological amplitude of teasel and its ability to occupy spring habitats.
Musk thistle (Carduus nutans). another exotic species that is similar in, appearance to thistles, has been increasing in New Mexico and occurs in the Sacramento Mountains. Proposals to introduce biological controls for the musk thistle may pose a threat to similar native species like Sacramento Mountains thistle, and should not be implemented until possible effects on the sacramento Mountains thistle have been determined.

This law prohibits the taking, possession, transportation and. exportation, selling or offering for sale àny listed plant species. Listed species can only be collected under permit from the state of New Mexico for scientific studies and impact mitigation.
A permit is also required
to collect plants from the Mescalero Indian
Reservation and Lincoln National Forest.
Section 7 ReQUirements. Section 7 of the Act requires Federal
agencies to ensure that their actions are not likely to jeopardize the continued existence of endangered or threatened species. Consultation with the Service may be informal (requests for list of species of concern, or proposed action) or formal (when a Federal~ discussion of effects of a agency such as the Forest Service or Bureau of Indian Affairs determines that a project may affect a listed species). Many informal consultations and one formal consultation have taken place between the Service and the Forest Service over the Sacramento Mountains thistle.
Conservation Plannina and Manaaement bv the Forest Service. To mitigàte grazing impacts, the Forest Service has constructed a total of 13 livestock exclosure fences around a total of 294 acres of thistle habitat (Table 1). Most of these exclosures are very small (less than, 2 hectares or S acres) and cannot be treated as management units except for total exclusion of livestock.

ob;ective and criteria
The main objective of this recovery plan is to protect and manage the habitats necessary to sustain healt~y populations of Sacramento Mountains The following actions are required to meet this objective and to thistle. allow the removal of the Sacramento Mountains thistle from the Federal list of threatened and endangered species.
1. Acquire water rights specifica~ly for the maintenance of travertine percent of the occupied spring spring habitats at a minLmum of 30
localities, including at least 1 occupied spring locality in each of the 20 known canyons of occurrence.
2. Develop habitat management plans to alleviate threats to the species and ensure permanent protection of at least 75 percent of the knoWn occupied habitats according to steps outlined in the plans. Sites should include both core populations at springs as well as other occupied riparian habitats. Unoccupied stream habitat downstream of occupied springs should be protected for future colonization by the
thistle.
3. Establish a ia-year monitoring and research program to demonstrate the effectiveness of management implemented under the plans.
There are 20 main canyon systems that have suitable habitat occupied by the Sacramento Mountains thistle. The iarqest and best representative spring habitat in each canyon system should have the water rights acquired for habitat maintenance by the land management agency. At present, there is no mechanism to, acquire these rights without a developed point of diversion and stated beneficial use. Therefore, until the State of New Mexico adopts instream-flow or similar legislation, the Sacramento Mountains thistle must remain listed as thr~atened under the Act.

These laws include the Endangered Species Act, the New Mexico Endangered plant Species Act, the Lacey Act, the National' Forest Management Act, and the National Environmental Policy Act. The service should also encourage the Mescalero Apache Tribe to include protection of this species in the Tribal code. All Federal agencies should conduct required consultations with
the Service under Section '7 of the Act.

This will require dispersing livestock from riparian areas or creating small pastures to divert cattle from these areas when necessary. No livestock facilities or holding traps should be constructed on or near occupied
habitat.
142. Timber harvest and road construction. Present Forest Service policy to avoid known populations in timer harvest and road construction operations by using a
200-foot buffer area should be continued. Nothing is
known, however, about the indirect hydrologic and erosional' effects of these activities on the Sacramento Mountains thistle. populations of Sacramento Mountains thistle in the vicinity of timer sale areas should be monitored during harvest.

research has already been carried out on this species. However, additional searches, monitoring, and research on population genetics, exotic species competition, and the effects of land use impacts on habitats is still needed to prevent decline of this species.
21. ~ocate all populations of sacramento Mountains thistle. Conduct surveys of unexplored springs on the Mescalero Apache Reservation to determine the complete range of this species.
22. Monitor population trends. Monitor all known populations on
public land to determine if management plans are accompliShing the desired goals. In most cases, long-term monitoring can be accomplished with Annual photographs from fixed photo points, in combination with recording the number of rosettes, flowering stalks, and life stage classification (including flowering,
non-flowering, and juvenile stages).

23. Beoin exoerimental orazino treatments. The effect of managed
grazing should be assessed on valley bottoms that contain streamside and spring habitats. Grazing intensity and duration should be controlled by either herding operations or manageable units of pasture. constructing a fence around Grazing treatments should include periods of use when teasel is somewhat palatable. These treatments should be compared to adjacent ,populations that are completely exclosed from
livestock.
24. Develop a hvdroloaic model for occupied habitat. Develop a
hydrologic model that identifies the groundwater recharge areas for occupied surface water habitats. Use this model to determine the effects of logging or other large area disturbance operations on the perennial flow of water in springs and streams.
25.
Develop sediment delivery model for vallev bottom habitats. The limits of total watershed disturbance (logging, grazing, and roads) should be determined on the basis of a model that describes erosion and/or sediment delivery to valley bottom populations of Sacramento Mountains thistle.

26.
teasel plant encroachment on occupied habitats. Teasel encroachment on saturated travertine habitats has not occurred to any great extent at this time. This situation should be monitored, since teasel can compete with the Sacramento Mountains thistle if it can invade these travertine spring
habitats.
27.
Bioloaical controls. Biological controls may also threaten the Sacramento Mountains thistle. Proposals to introduce biological controls for the exotic musk thistle may pose a threat to similar native species like Sacramento Mountains thistle, and should not be Lfplemented until possible effects on the Sacramento Mountains thistle have been determined.
Studv the oenetic relatedness within and between populations. Génetic studies should be conducted to determine the extent of asexual reproduction within populations. Studies should also be conducted to determine relatedness between populations and the role of scattered streamside plants in genetic transfer betweèn larger populations. These studies should include seed dispersal, 'pollen flow, and the movement of genetic material between populations.

Prîncîpal Comments Received on the Draft Sacramento Mountains Thistle Recovery Plan and Service Responses
Availability of a Draft Recovery Plan for the Sacramento Mountains thistle
,-
for review and coment was published in the Federal Reoister (Vol. 57
No. 155) on Augu~t 11, 1992. The public comment period ended septemer 25, 1992. The comment period was extended upon request from the Forest Service until October 23, 1992.
There were twelve requests for copies of the Sacramento Mountains Thistle Draft Recovery Plan. Four letters were received: two from Federal agencies, one from a grazing association, and one from a professional botanist. Comments of a similar nature are grouped together. Substantive 'comments that questioned approach" methodology, or financial needs called for in the draft plan, or suggested changes to the plan, are discussed below. Comm~nts related to the original decision, or regarding the Act and not related to the Sacramento Mountains thistle, were not included. comments were also received. Supportive
All comments received were considered when revising the draft plan, and retained as a part of the Aaministrative Record for the Sacramento Mountains thistle at the New Mexico Ecological Services state Office.
Comment: Generally, the draft plan
is well written and reasonable. It

be recovered through the implementation of management actions outlined in the recovery
Service Response: The Service believes this species can
plan.
Comment: This document falsely states that the Sacramento Mountains thistle is threatened by improper livestock management.
Service Response: Over the past decade, both direct and indirect impacts
of grazing have been observed by the Forest Service in the Sacramento Mountains thistle populations. Fencing and herding of livestock away from the thistle have occurred only in recent years. The effects of grazing on the thistle ~ill continue to be monitored and evaluated by the Forest
Service.
Comment: The document states that in one valley, the
plants were severely
impacted by livestock grazing. Except in riparian areas, the thistles are
not found i~ valleys.
Service Response: Although travertine substrates at springs and streams more densely occupied, the thistles have been documented in one valley. are These plants are less palatable, spinier and tougher than other populations
studied.

Comment: The plan falsely states that little effort was made to evenly distribute livestock grazing by herding or fencing, and thus, resulted in severe grazing impacts of valley bottoms.
Service Response: The Service recognizes that in recent years permittees
have made an effort to reduce grazing impacts through herding. The Forest Service has also fenced several plots. These joint efforts have helped riparian areas. This is noted in the final recovery reduce impacts in
plan.
Comment: There is concern that portions of the draft plan may be more specific than is needed. For instance, the Forest Service completed a formal consultation on grazing that explores the compatibility of various grazing systems with Cirsium vinaceum. and small pastures may not be optimal for the recovery of the species.
Service Response: ~f small pastures are not beneficial to the recovery of
the Sacramento Mountains thistle, theft a different approach
'should be used.
This change has been incorporated into the final recovery plan.
Coment: The Sacramento Grazing Association has also monitored the thistle plants closely, and page four of this document states that monitored populations are, somewhat stable. A close inspection of the plants show that they are more than "somewhat stable," they are thriving.
--
Service Response: It was determined that mortality and reèruitment were populations. However, this is "somewhat stable" in the monitored thistle not true for all extant populations of the thistle.
Comment: According to this document, there are 293.53 acres exclosed. The Sacramento Grazing Association had a letter from the Forest Service stating there are 417 acres of exclosures for the thistle, with plans for only two additionäl exclosures ia Lucas Canyon. However, listed in the recovery plan were exclosures in Hubbell, Mauldin, Lower Mauldin, and several more in Water Canyon.
Service Response
i The number of acres with grazing exclosures is from information provided by the Forest Service.
task. .
Comment: Because of significant improvement in grazing management and habitat conditions, the Forest Service proposed the Service reconsider the implementation Table, which places livestock management as a "Priority 1"
Service Response: Data on effects of grazing on the plants are
conflicting. Some thistle populations have improved, while others declined in fenced and unfenced populations. The Forest service should continue monitoring and evaluating grazing impacts on the thistle. Because the habitat of the species is critical to its recovery, and the thistle will not revegetate in heavily disturbed areas, the task remains
"Prior ity 1."

Comment: The plan states that impacts from wildlife grazing and predatioa are less than those observed from livestock.
Service Response: studies have been inconclusive. Therefore, it was not included in the final plan.
Comment: If plants must live in saturated lands, the potential threat from logging is preposterous. No logging ever occurs in riparian areas.
Service Response: Indirect effects from logging, such as road construction, siltation, alteration of hydrologic flows, increased surface water runoff, decreased infiltration, and higher sediment loads in streams,
can occur.
Comment: The Forest Service asked for a reconsideration of the Implementation Table, which place.s "logging practice impacts" as a "Priority 1" task.
Service Response: More monitoring studies need to be done to determine
consider reducing this task priority number.

Coment: The recovery goals identified in the plan are defined in terms of
a percentage of' the total known populations rather than what is biologically needed to recover the species, suggesting that all populations are not needed for recovery, and raising ~estions about the threatened status of the species.
Service Response: The preservation and management of habitat are important to recovery of this species. Water rights must be acquired for the conservation of spring habitats for at least 30 percent of the occupied spring localities, including at least 1 occupied spring locality in each of the 20 canyons in which it occurs. Additional biological studies, including research on exotic species competition and biological controls, are also essential for recovery.
comment: The Implementation Schedule includes cost_ estimates that do not
accurately reflect what the Lincoln National Forest believes is needed to implement the tasks identified.
Service Response: We have incorporated cost estimates provided by t~e
Lincoln National Forest in the final plan.
Comment: Is the policy of water diversion to be implemented for all
suitable habitat whether it is occupied or unoccupied?
Service Response: case-by-case based habitat, and total In the largest and system, a point of
point of water diversion will be determined on the numer of plants at the site, Buitability of Sacramento Mountains thistle occupancy in the canyon. best, representative spring habitat in each' canyon diversion should be prohibited within suitable habitat.

The Forest service, as the land management agency, should determine where the point of diver~ion would be least likely to affect the Sacramento Mountains thistle or its habitat.
Comment: If the point of diversion policy is an effective means of ensuring continued availability of spring habitat for the species, then why would water rights also need to be obtained?
Se~vice Response: The unauthorized development of a spring near Bluff Springs resulted in a net loss of 84 percent (300 in 1984 to 47 in 1991) of one population and demonstrates the importance of acquiring water rights
within spring habitat.
Comment: How can recreationalists impact the Sacramento Mountains thistle? This species is so thorny and dense that a person could not walk through
it.
Service Response: Habitat and plants are destroyed in areas of
off-road vehicle traffLc, or indirectly by
concent,rated human use. This c.an be done directly, for instance,' by diverting water from suitable
habitat.
Comment: The Forest Service recommended the priority number assigned to recreation be changed from Priority 2 to a lower number.
Service Respdnse: Running water attracts a large number of forest users, campers, and sightseers who directly and indirectly impact the thistle. Based on the current. and best available information, recreation is a potential threat to the species, and therefore, the Service believes that regulation of recreational activities should remain a Priority 2 task.
Comment: Why does the Forest Service need to "close unne,cessary roads?"
Service Response: Roads attract people and increase recreational use,
inciuding off-road vehicle traffic.
