I . INTRODUCTION

This report summarizes the results from three years of
demographic monitoring studies in populations of Penstemon
lemhiensis. a sensitive plant species that occurs on the
Beaverhead and Bitterroot National Forests in Montana.
Three permanent transects were established in 1989 on the
Beaverhead National Forest. The monitoring results from
1989 and 1990 are discussed in earlier reports (Shelly 1990,
Achuf f and Shelly 1991) .

II. SPECIES INFORMATION

A. REVIEW OF PRESENT STATUS

1. FEDERAL STATUS: Penstemon lemhiensis is currently
designated as a Category 2 candidate for federal
listing by the U.S. Fish and Wildlife Service
(U.S. Department of Interior 1990) . Category 2
taxa are those "for which there is some evidence
of vulnerability, but for which there are not
enough data to support listing proposals at this
time. "

Penstemon lemhiensis is also currently on the U.S.
Forest Service Region 1 sensitive species list
(U.S. Department of Agriculture 1988; Reel gt al.
1989) . Sensitive species are "plant and animal
species identified by the Regional Forester for
which population viability is a concern, as
evidenced by: a.) significant current or
predicted downward trends in population numbers or
density, and/or b.) significant current or
predicted downward trends in habitat capability
that would reduce a species' existing
distribution" (Reel gt al* 1989) .

2. STATE STATUS: In Montana, Penstemon lemhiensis is
currently ranked as S2 ("very rare and local
throughout its range") by the Montana Natural
Heritage Program (Achuff 1991) . It is also
currently categorized as "threatened" in a recent
evaluation of rare plants in Montana (Lesica and
Shelly 1991) . A "threatened" species is one which
is "likely to become endangered throughout all or
a significant part of its range in Montana in the
foreseeable future. Specific threats to known
populations of these plants have been identified"
(Lesica and Shelly 1991) . These state rankings do
not currently provide any legal protection for P.
lemhiensis.

B. UPDATE OF GEOGRAPHICAL DISTRIBUTION (MONTANA)

No additional populations of Penstenon lemhiensis were
newly discovered in Montana in 1991. Thus, the total
number of known element occurrences in the state
remains at 44. Of these, 42 have been recently
documented (1983-1990), one recent report (1987,
Medicine Lodge Cree)c) has not been relocated, and one
is an unverified historical record (1947) (Montana
Natural Heritage Program database, Helena) .

C. POPULATION DEMOGRAPHY AND MONITORING STUDIES

1. DEMOGRAPHIC STUDIES

The three permanent monitoring transects
established in 1989 were re-read on 29-30 July
1991, using the methods described in a previous
report (Shelly 1990) . The population and
fecundity data are summarized in Table 1. The
numbers of plants and the numbers of fruiting
individuals, for each transect over the three-year
study period, are displayed in Figures 1-3, pp. 4-
6.

In 1991, the total number of plants in the three
transects was 115. This total represents a severe
continuing decline, from 240 plants in 1989 and
215 plants in 1990. Once again, further decreases
occurred in the French Creek - Park Mine and
Badger Pass North transects. Total population
size decreased from the 1990 level at the French
Creek - Discovery Mine transect, but equalled the
original total present in 1989.

The total number of plants in the French Creek -
Park Mine transect decreased by 31 from the 1990
total, resulting in a population decline of 52%.
Extensive sheet erosion appears to be continuing
at the site, and may have been a contributing
factor in the loss of the 55 established plants
that have not survived from 1989 to 1991. The
fecundity and vigor of the surviving individuals
in this transect was drastically lower in 1991; no
plants flowered or fruited. Additionally, no
fruiting plants were found in the vicinity of the
transect, so we were unable to collect data on
seed production for this site.

The total number of plants at the French Creek -
Discovery Mine transect decreased by 12 in 1991,
resulting in a -25.5% population growth rate.

Thirteen established plants have died since 1989.
As at the Park Mine transect, the plants at
Discovery Mine showed no reproduction in 1991.
This represents an even moresevere reproductive
decline in this case, as 24 of the 47 plants
present in the transect in 1990 had flowered and
produced fruit (see Fig. 2) . As at the French
Creek - Park Mine site, no fruits could be
collected in order to determine seed production.
Of the populations in the three study transects,
the French Creek - Discovery Mine population has
been the most stable over the three-year study
period in terms of total numbers. However, until
1991 it had the lowest density of plants per m^.

The total number of plants in the Badger Pass
North transect decreased by 57 in 1991, resulting
in a 53.3% population decline from 1990. Sixty-
seven established plants died between 1989 and
1991. This transect contained the only fruiting
plants found in 1991, but the percentage of such
plants was much reduced from 1990 levels (18%,
compared to 45.8% fruiting in 1990) (see Figure
3) . Other measures of fecundity, including the
mean number of fruits per fruiting plant, the mean
number of fruits per inflorescence, and the mean
number of seeds per fruit, were also reduced from
1990 levels. The percentage of aborted flowers
increased to its highest level to date in this
transect for the three-year study period. Lastly,
the percentage of flowering stems browsed in this
transect increased from 2.9% in 1990 to 20.0% in
1991.

The rosettes of most of the surviving plants in
the three transects were much reduced in vigor in
1991. They were much smaller in size, and the
majority of the green leaves appeared to have been
damaged by insects. Thus, it is possible that
many plants will continue to perish in future
seasons, owing to their severely weakened
condition.

The reasons for the severe population declines are
currently unknown. Ongoing drought conditions in
Montana, possibly coupled with extremely cold
weather during the winter of 1990-91, may be
contributing factors. No evidence of severe
direct disturbance, i.e., from grazing or other
vegetation-disturbing activities, has been
observed in the three transect locations over the
last three years. A weather data recording

station has been established at the Badger Pass
site (BLM land) , and may provide some insights
regarding possibly influential climate patterns.

Additional demographic monitoring studies were
established in 1991, for two populations on Bureau
of Land Management lands in southwestern Montana
(Achuf f 1992) . These additional monitoring data
should further advance an understanding of the
overall population trends.

2. POPULATION NOMITORIHO

Two previously documented populations were
revisited in 1991. The Red Butte population
(012), which contained 142 plants when it was
first documented in 1986, consisted of fewer than
five living plants in 1991. Similarly, the Kearns
Creek population, which consisted of 52 plants
when it was documented in 1987, contained only
three living plants in 1991. These results, along
with the observations from the monitoring
transects, indicate that numerous populations of
£. lemhiensis in Montana are experiencing severe
declines.

III. ASSESSMENT AND MANAGEMENT RECOMMENDATIONS

A. MANAGEMENT RECOMMENDATIONS t The drastic declines in
population numbers and fecundity over the last three
years indicate that £. lemhiensis populations are
experiencing a severe "bottleneck" in southwestern
Montana. These declines are undoubtedly placing many
populations in increased jeopardy, and rendering then
even more vulnerable to management activities that nay
disturb occupied habitats. For this reason, extreme
caution should be exercised in the vicinity of all
known populations. It will be especially inportant to
maintain the larger populations occurring in natural
habitats, as these will provide the most likely sources
for future population reestablishment and recovery.

The recent, severe population declines, coupled with a
vulnerability to management activities, indicate that
Penstenon lemhiensis should remain on the sensitive
species list for Region 1 of the U.S. Forest Service.

Preparation of a U.S. Forest Service species
conservation strategy has been initiated. This
strategy will provide detailed, population-specific
nanagenent and conservation guidelines for £.
lemhiensis.

B. PROPOSALS FOR FUTURE STUDIES

The first three studies listed below are recommended
for continuation during the next two field seasons. In
addition, other detailed studies regarding the biology
and ecology of p. lemhiensis are suggested.

1. Demographic monitoring studies in the permanent
transects should be continued in 1992 and 1993.
Upon evaluation of population trends after the
1993 season, a plan for continued periodic
monitoring should be developed.

2. Field checks of known populations should be
continued, especially in those that have declined
recently, such as Badger Pass (005) , Red Butte
(012), Erroont Gulch (014), and Kearns Creek (018).
These population surveys, coupled with the
demographic studies, will provide an ongoing
measure of population levels in Montana.

3. Continue field surveys for new populations in
areas of potential habitat in southwestern
Montana.

4. Detailed, sophisticated studies are needed
regarding the life history and ecological
requirements of £. lemhiensis. Such information
is required for the development of sound
conservation strategies (Massey and Whitson 1980) .
In conjunction with the Center for Plant
Conservation and the Denver Botanic Gardens,
aspects of seed germination behavior and seed bank
dynamics could be studied. These organizations
are actively pursuing studies of threatened and
endangered plants in the northern Rocky Mountain
region, and are collecting seeds of such species
for inclusion in the national endangered plant
seed bank. Owing to the recent, severe population
declines, it is recommended that P. lemhiensis be
included in these efforts.

5. Recent field surveys in Idaho (Moseley et al.
1990) suggest that an additional factor
contributing to population declines may be
advancing vegetation succession, i.e., as a result
of ongoing fire suppression. Further studies
addressing this hypothesis, perhaps coupled with
some experimental burns in occupied habitats, may
provide further information regarding the
influence of plant community dynamics on known
populations of £. lemhiensis.

APPENDIX - DEMOGRAPHIC MONITORING TRANSECT DATA

The performance of individual Penstemon lemhiensis plants in the
permanent monitoring transects, from 1989 to 1991, is detailed
below. The following codes are used:

A - aborted flowers (no fruit development apparent)

B - browsed flowering stem

C - established immature plants (rosette with <4 leaves)

D - dead

F - fruit

I - inflorescence (flowering stem)

P - predated fruit

R - rosette (basal tuft of leaves on mature plant)

S - seedlings (cotyledons evident or rosette <15 mm in
diameter) .

The codes form a formula describing the state of each plant. For
example, R5-I2-F17-A25 is a plant with 5 basal rosettes, 2
inflorescences, 17 fruits, and 25 aborted flowers.
