Introduction

This is a preliminary checklist for Tamarack, Round and Long Valleys in the San Jacinto Mountains. These valleys contain nearly all of the higher elevations of San Jacinto Mountain on the east of San Jacinto Peak, ranging from 8,240 to 10,000 feet in elevation.

These valleys together are a remnant flattish surface of about 2.3 square miles (5.9 square km) with a maximum extent of about 2.3 miles (3.7 km) east-west and 1.4 miles (2.2 km) north-south. This surface is being gradually destroyed from the edges by erosion due to the much lower elevations to the north and east.

The flora from these three valleys is presented together here, since these valleys are only weakly separated topographically, and the flora is fairly uniform throughout. The very small (0.05 square miles) Hidden Lake drainage basin is not included in this area since its flora is significantly different from the rest of this area; see its separate flora.

This checklist has been compiled from online vouchers, from fieldwork targeted on specific locations within this area, and from the portion of our plant trail guides in this area.

This checklist is very preliminary for at least six reasons:

1. The data from many days of fieldwork have not yet all been processed, and so this list will change significantly in the future.

2. The vouchers are only from online records, which do not yet include all vouchers.

3. Most vouchers have not yet been reviewed for reasonableness.

4. Some observed species (Gayophytum, Juncus, Carex and a few grass species) have not yet been determined, and hence are not stated in the checklist below as being observed. Thus some of the taxa listed here as not having been observed will be recorded as observed in future updates.

5. Some of the species listed as being observed are not yet 100% determinations, and need to be confirmed from further work, primarily from collected specimens.

6. Some portions of this area have not yet been surveyed. In particular, Tamarack and Long Valley Meadows have not been fully surveyed, and Round Valley Meadow has only been surveyed at one time in the year.

Even though this checklist is only a working draft, we've placed this online for three reasons:

1. It will be useful to a number of people;

2. It is interesting; and

3. Lists have to start with something. With even a preliminary list, botanists can check to see if an observed or vouchered taxon is on the list, and if not, it can be added. Please let us know if you run across a voucher, or see a species, in this area that is not on this list!

Location

The following map shows the location of the floral area targeted here:

The heavy solid purple line surrounds the outer boundaries of the union of these three valleys.

The dashed purple lines delineate the boundaries of each individual valley. The western edges of Tamarack and Round Valleys are taken to be the 10,000 foot elevation contour; the flora of the area above 10,000 feet elevation will be given separately. (Until that flora is put online, see Flora of San Jacinto Peak, which includes all but two of the taxa found above 10,000 feet elevation.)

The northern and eastern boundaries are taken as the edge of the lip of the flattish surface, above the precipitous slopes below. The southern boundary is the ridgeline along the Wellman / Hidden Lake Divides that separates this area from the Tahquitz Valley to the south.

Tamarack and Round Valleys are fairly clearly separated by the low ridge the divides the drainages of Tamarack Creek and Round Valley Creek. The boundary between those two valleys and Long Valley is somewhat arbitrary since those two creeks have carved significant east-west canyons into the weak north-south ridge that separates these two higher valleys from the lower Long Valley. Outside of those canyons, the western boundary of Long Valley is fairly unambiguous, following the ridge that divides drainage directly into Long Valley Creek from drainage into its two tributaries. We have somewhat arbitrarily simply joined those ridges by a straight line to complete the western boundary of Long Valley.

With this definition, the elevation extremes for each valley, along with the elevation of the biggest meadow in each valley, are as follows:

Valley	Extreme Elevations (feet)		Meadow Elevation (feet)
	Min	Max
Tamarack	8,500	10,000	9,240
Round	8,500	10,000	9,000
Long	8,240	9,600	8,340

The highest elevation of Long Valley occurs at the peak immediately east of Cornell Peak; its lowest elevation is along Long Valley Creek. The lowest elevations of Tamarack and Round Valleys occur at the junction of those two creeks.

Solid blue lines are trails, most of which have been botanized extensively (see the plant trail guides for each one, but note that many of the guides do not include the latest fieldwork yet). Dashed blue lines are floristic surveys done once each so far that compiled checklists and estimated plant species abundances.

Most of this area is shown in this photograph taken by James Dillane from the trail from Wellman Divide to San Jacinto Peak on 7 August 2007, near the 10,000 foot western border of Tamarack Valley:

See also picture without labels. Note that this picture exaggerates the size of Tamarack Valley since that valley is closest to the photographer.

Procedure For Compiling The Checklist

(To be supplied)

Important Caveats

Please note the following important caveats about this preliminary Checklist:

• We have not looked at any of the vouchers yet, so we cannot vouch for their determinations. We have checked only the names of the taxa to make sure it was not unreasonable for them to occur here.

• This is a very preliminary first draft Checklist, compiled quickly and without review by other knowledgeable botanists, and so well may contain bonehead errors.

Change in Checklist With Time

Date	# Taxa	# Vouchered	# Observed	Comments
4 August 2008	127	84	102	Initial Checklist Created
16 August 2008	144	87	122	Results added from three additional surveys, one additional vouchered species, and one removed taxon

The number of vouchered taxa increased by these three taxa in the 16 August 2008 update:

• We included vouchers of two species which had locations from canyons of the east side:Acer glabrum var. diffusum and Ivesia saxosa, since we found both species in Long Valley.

• Apocynum androsaemifolium was excluded from the previous list since the voucher just says Vicinity of Tamarack Valley. However, Hall in his Flora states it was Collected at 8500 ft. alt. in Round Valley, so we have now included it.

The increase in the number of observed species by 17 resulted from the inclusion of the results from three surveys done on 5, 8 and 12 August 2008 of northern Long Valley, the Cornell Peak ridgeline area, and southern Long Valley, respectively.

Checklist for Tamarack, Round and Long Valleys

The Checklist is sorted first by category - ferns, dicots, and monocots - and then by family and scientific name. The Family and Scientific Name are from the Jepson Manual. An asterisk before the Common Name would indicate a non-native taxon, but all of the taxa found so far here are native, an amazing rarity in southern California.

The next columns give the following information:

Column	Meaning
#S	The total number of surveys in which each taxon was found. As of 16 August 2008, we have surveyed 13 separate areas, estimating the plant abundance in each of them. The areas range from narrow transects along trails, to surveys of fairly large areas. See checklist sorted by plant abundance for a histogram of the total number of surveys for each taxon.
#Pl	This is the maximum number of plants and the maximum number of locations for each taxon, separated by a slash, from all the estimates made in each of our field surveys. Maximum values are 99 plants, and 9 locations, recorded below as 99/9. The main intent of this column is to indicate the species for which we found few plants or locations. Taxa recorded as 99/9 are widespread taxa in at least one of the field surveys, but may be absent entirely from others. Check the #S column to see how widespread each taxon is for all surveys.
V	If a taxon has been vouchered from any of these three valleys, a V is given in this column.
O	If we have observed a taxa anywhere in these three valleys, even if the taxon was not in a formally-surveyed area but was found in an adjacent not-formally-surveyed area, an O is given in this column. For example, Salvia pachyphylla was found in lower Tamarack Valley, observed on our way to doing two surveys in upper Tamarack Valley; and also found in an unsurveyed area along the Desert View Trail in Long Valley. But it never appeared in any formally-surveyed area, and hence never had an abundance estimate made for it.
L, T, R	A taxon observed or vouchered from Long Valley (L), Tamarack Valley (T), or Round Valley (R).
W	If a taxon is only found in a wet area such as a seep area or along a moist drainage, a W is given in this column. Note that species which can be found outside of wet areas will not be so marked, even though they may be found almost entirely in wet areas here.

The Checklist contains 144 taxa, 87 of them vouchered and 122 of them observed by us in this area. Of the 122 taxa we have observed, 66 of them (54%) have been vouchered. With very few exceptions, the unvouchered species have vouchers from nearby areas at slightly lower elevation.

We have not yet definitely seen 21 of the 87 vouchered taxa, 24%, as well as one additional species mentioned by Hall as occurring here (Perideridia parishii, but which is not vouchered by anyone.

The final checklist will contain only vouchered specimens. We will be collecting vouchers in the future, under permit from the State Park, to document the taxa that are currently unvouchered in this area.

Some of the species listed as being observed are not yet 100% determinations, and need to be confirmed from further work, primarily from collecting and determining specimens, but also for other reasons as well. For example, here are two species in the latter category:

• We found only a single plant that appeared to be Rhamnus ilicifolia from its leaves. This specimen was only a few inches high, with thick woody stems, but without flowers or fruit.

• We found two occurrences of an Arabis that appears to be Arabis breweri var. pecuniaria, a rare plant that was previously known to occur only near Dollar Lake in the San Bernardino Mountains. Due to the well-known difficulties in Arabis taxonomy, our specimen will be sent for review by an expert.

Taxa present in the Checklist without a voucher or our observation come from reports in Hall (1902).

Some vouchers by Hall, given simply as Round Valley, or Tamarack Valley, or Vicinity of Tamarack Valley, cannot be definitely placed in one of the three valleys here. Hall mostly did not use the name Long Valley at all, and used the names Round Valley and Tamarack Valley as equivalent names for the combined valleys. These vouchers are therefore not given as being in any specific one of the three valleys.

Sometimes the elevations given for the vouchers with locality Vicinity of Tamarack Valley are below any elevation in the combined valleys. Such vouchers were excluded from this checklist.

See also the list of rejected species given below, and the checklist sorted by plant abundance.

This is a working list, about which we make no guarantees at all until we officially release it. Use at your own risk!

Taxa Rejected From The Checklist

Taxa Rejected Due To Uncertain Locations

Dodecatheon redolens, POM19641. The location of this voucher is given as San Jacinto Mountains region Round Valley, Elev. 8000-9000 ft.. All other vouchers of this species are from Deer Springs, on the west side of the mountain below Round Valley. We have found this taxon at only one other location, also on the west side. Hence we feel it is likely that this voucher also came from the west side.

Taxa Rejected Due To Probably-Incorrect Determinations

None so far.

Other taxa rejected from the list

Trifolium longipes var. nevadense. We inadvertently included this taxon in the first version of this checklist from a misreading of Hall's discussion on page 30 of his flora. This species is apparently confined to Tahquitz Valley at lower elevation.

Interesting Taxa Not Present In The Checklist

This section was added to the original checklist, since the original checklist was missing both Heuchera hirsutissima and Selaginella watsonii, yet both species were abundant both above (at San Jacinto Peak and Miller Peak) and below this area (at Chino Canyon and Tahquitz Peak). We have since found both taxa here.
