Please Note: This report includes the same summary and background information as the Fall 2002 report, so that it 
can function as a stand-alone report for readers. This report, including Appendices A-D, is included on the compact 
disk that accompanies the report. The disk also contains all of the project photographs, organized into folders for 
each project area with each photograph dated. 

I. Abstract 
Tributaries and side canyons of the Colorado River, and seeps and springs in Grand Canyon 
National Park (GCNP), are among the most pristine watersheds and riparian habitat remaining in 
the coterminous United States. These riparian systems deserve a high level of protection from nonnative 
plant invasion. The encroachment of tamarisk into these tributaries poses a significant threat 
to the integrity of the natural ecosystems. GCNP and the Grand Canyon Wildlands Council 
(GCWC) are committed to the preservation of native plant communities and native ecosystems. 
National Park Service (NPS) Management Policies require park managers to maintain all the 
components and processes of naturally evolving park ecosystems, including the natural abundance, 
diversity, and genetic and ecological integrity of the plant and animal species native to those 
ecosystems (NPS 2001b). Park managers are directed to give high priority to the control and 
management of exotic species that can be easily managed and have substantial impacts on the 
Parks resources (NPS 1985, NPS 2001b). 
The primary objectives of this portion of the overall project are to remove tamarisk from 63 
tributaries of the Colorado River in Grand Canyon National Park, and to monitor the success of the 
tamarisk removal through pre- and post-removal plant monitoring. This project will significantly 
reduce tamarisk distribution within the treated areas, and allow native vegetation to reestablish 
without exotic plant competition. Prior to initiation of the project, park staff completed extensive 
public scoping and prepared an Environmental Assessment / Assessment of Effect (EA/AEF). 
Under the Directors Orders on Compliance (NPS 2001a), staff considered the cumulative effects of 
multiple projects, and included an analysis of tamarisk removal in all of the parks tributaries. After 
review of the public comments, GCNP issued a Finding of No Significant Impact (FONSI) for the 
project in June 2002. Upon completion of the FONSI, GCNP restoration biologist Lori Makarick 
worked with the GCWC to revise the Tamarisk Eradication Plan, budget and contract for this 
project, and then began to plan the logistics for the fall 2002 river trips. 
Project leaders and crew members conducted the first two eradication trips in the fall of 2002, and 
the second two eradication trips in the fall of 2003. GCNP staff, supported the NPS Exotic Plant 
Management Team (EPMT) based in Lake Mead National Recreation Area, completed one 
additional trip in March of 2003. Colorado River Fund monies supported the trip, and participants 
completed work in the 63 areas included in this AWPF funded project. During September 2003, 
volunteers manually removed seedlings in eight of the tributaries included in this AWPF funded 
project; the National Park Services Cooperative Conservation Initiative funded that work. With all 
of these trips combined, crews have removed over 56,000 tamarisk trees in 68 project areas. The 
2003 AWPF funded trips were extremely successful, and this project (Phase I of the parks overall 
tamarisk management project) is nearing completion. This report will summarize all of the work 
completed to date on this project, and will detail the remaining work that will be completed in the 
spring of 2004. 

II. Introduction 
a. Overview of project status. 
The tamarisk eradication portion of this overall project within Grand Canyon National Park (GCNP) 
is nearing completion. The National Park Service (NPS) worked for two years to complete the first 
task listed in the above contract. The task was to obtain all permits and environmental clearances 
necessary to conduct the proposed work. The compliance process was longer than anticipated, due 
to new compliance guidelines, issued in 2001. The new guidelines, Directors Order #12: 
Conservation Planning, Environmental Impact Analysis, and Decision Making, required that NPS 
complete public scoping and documentation prior to the initiation of this project (NPS 2001a). The 
documentation aims to ensure the use of interdisciplinary approaches and principles to decisionmaking, 
and that all decisions are based on technical and scientific information (NPS 2001a). 
Public scoping and interdisciplinary team discussions about tamarisk management had been 
ongoing since 1998. The NPS issued the final Environmental Assessment / Assessment of Effect 
for the project to the public in February 2002. Staff received and analyzed public comments, and 
prepared a Finding of No Significant Impact Statement (FONSI), signed by the regional office on 
June 18, 2002. The park received a written response to the Informal Consultation with the U.S. 
Fish and Wildlife Service (USFWS) on January 25, 2001 and that letter, along with the 
incorporation of their recommended changes, completed the Section 7 consultation that was 
necessary for this project. On April 8, 2002, the State Historic Preservation Officer (SHPO) 
provided the park with written concurrence on the project moving forward. 
By mid-June 2002, all of the necessary permits and clearances for this phase of the overall project 
were in hand. Project leaders revised the Tamarisk Eradication Plan to incorporate the new project 
timeline, which is as follows: 
 October 2000  18-day river trip, transect installation and monitoring 
 October 2002  18-day river trip, eradication trip #1 
 November 2002  18-day river trip, eradication trip #2 
 October 2003  18-day river trip, eradication trip #3 
 November 2003  18-day river trip, eradication trip #4, and post-project monitoring and 
follow-up maintenance 
 Spring 2004  18-day river trip, post-project monitoring and follow-up maintenance 
At this time, this project is right on track and completion is near. Project leaders and crew members 
conducted the first two eradication trips in the fall of 2002, and the second two eradication trips in 
the fall of 2003. With the project initiated, the NPS received additional assistance for this project. 
GCNP staff, along with the NPS Exotic Plant Management Team (EPMT) based in Lake Mead 
National Recreation Area, completed one additional trip in March of 2003. Colorado River Fund 
monies supported the trip, and participants completed work in 14 of the 63 areas included in this 
AWPF funded project. During September 2003, volunteers manually removed seedlings in eight of 
the tributaries included in this AWPF funded project; the National Park Services Cooperative 
Conservation Initiative funded that work. The public and volunteers have also been supportive of 
this project, and the NPS is seeking additional funds to extend this project into the next phases. 
The fall 2002 report included information about the first two eradication trips. This report combines 
that information with the 2003 results and provides a picture of the work completed to date. The 
2003 AWPF funded trips were extremely successful, and this project (Phase I of the parks overall 
tamarisk management project) is nearing completion. This report will summarize all of the work 
completed to date on this project, and will detail the remaining work that will be completed in the 
spring of 2004. 
b. Justification for recent work 
Tamarisk (Tamarix sp.), commonly known as salt cedar, is an invasive, exotic shrub or tree that 
grows in dense stands along rivers and streams in the West. Tamarisk, introduced to the U.S. in the 
19th century as an erosion control agent, spread through the West and caused major changes to 
natural environments. Tamarisk reached the greater Grand Canyon area during the late 1920s and 
early 1930s, and became a dominant riparian zone species along the Colorado River following 
completion of Glen Canyon Dam in 1963. The impacts caused by tamarisk in the Southwest are 
well documented (refer to Reference Section of the EA/AEF and Stevens 2001). These prolific 
nonnative shrubs displace native vegetation and animals, create conditions that are inhospitable for 
the germination of native plant seeds, and increase fire frequency. Salt cedar is an aggressive 
competitor, often developing monoculture stands and altering water tables, which can negatively 
affect wildlife and native vegetative communities (Duncan 1996). In many areas, tamarisk occupies 
previously open spaces and is adapted to a wide range of environmental conditions. Once 
established in an area, it typically spreads and persists. 
Distinctive soil types, vegetation, and hydrologic conditions characterize riparian areas that provide 
biologically diverse and productive ecosystems. In the Southwest, riparian areas account for less 
than 2% of the land, yet over 65% of Southwestern wildlife depend on riparian habitats. Riparian 
habitats are the most productive, most valuable and most threatened habitats in the American 
Southwest (Johnson et al. 1985). Tributaries and side canyons of the Colorado River, and seeps and 
springs in GCNP, are among the most pristine watersheds and desert riparian habitat remaining in 
the coterminous United States. These riparian systems deserve a high level of protection from nonnative 
plant invasion. The recent encroachment of tamarisk into these tributaries poses a significant 
threat to the integrity of the natural ecosystems. GCNP is committed to the preservation of native 
plant communities and native ecosystems (NPS 1995a, NPS 1995b). NPS management policies 
require park managers to maintain all the components and processes of naturally evolving park 
ecosystems, including the natural abundance, diversity, and genetic and ecological integrity of the 
plant and animal species native to those ecosystems (NPS 2001b). Park managers are directed to 
give high priority to the control and management of exotic species that can be easily managed and 
have substantial impacts on the Parks resources (NPS 1985, NPS 2001b). The removal of tamarisk 
from these tributaries will provide this protection, and allow native plant communities to recover, 
with an expected increase in native plant species following tamarisk removal.

. Monkey flower (Mimulus cardinalis) 
. Mequite (Prosopis glandulosa) 
. Emory baccharis (Baccharis emoryi) 
III. Methods 
a. Area of interest in recent analysis 
Under this contract, crews will remove tamarisk from 63 areas within Grand Canyon National Park, 
selected based on the numbers of tamarisk trees found during the preliminary surveys (i.e. feasibility 
of control at this time) and the extent of the seeps, springs, and riparian habitat found within the 
project areas. 
High species diversity, high species density, and high productivity generally characterize riparian 
areas. Continuous interactions occur among riparian, aquatic, and upland terrestrial ecosystems 
through exchanges of energy, nutrients, and species. Warren et. al. (1982) provided the following 
description: 
gRiparian woodlands (or forests) characterized by cottonwood-willow associations are 
primarily restricted to the larger perennial streams and drainages of the Colorado Plateau 
region of northern Arizona. The great biological importance and floristic diversity of these 
cottonwood-willow riparian forests is disproportionate to their limited total areac. Riparian 
scrub usually occurs along ephemeral or intermittent watercourses (such as desert arroyos), 
or in narrow canyons which are periodically scoured by floods. Riparian scrub communities 
are characterized by a broad continuum of vegetative associations that range from mesic 
vegetation types to xeric growth along desert arroyos (Brown et al., 1980). These arroyos 
often contain water only one day or less each year and the resulting vegetation is commonly 
composed of a mixture of facultative riparian species and upland species. This is in contrast 
to mesic species, which are generally absent from the surrounding uplandsc. Side canyons 
throughout the park with perennial water support riparian vegetation characterized by 
cottonwood (Populus fremontii) and willow (Salix spp.) which is generally very similar to 
that found in similar situations throughout northern Arizona (Phillips and Phillips, 1979)c.h 
Each dry wash, spring, seep, or stream has a different association of species, depending on 
environmental features including elevation, permanence of water, substrate, frequency of flooding, 
and colonization (Warren et al., 1982). Riparian vegetation typically occurs in small, discrete stands 
or patches. The floristic diversity in wetland and riparian composition is highly variable, but is 
extremely high when compared to the upland vegetation. Typical stands may consist of broadleaved 
deciduous trees in the overstory, with a mixture of shrubs and grasses in the understory. 
Species typical of drainages with perennial water sources are: 
. Fremont cottonwood (Populus fremontii) 
. Brickellia (Brickellia longifolia) 
. Catclaw acacia (Acacia gregii) 
. Apache plume (Fallugia paradoxa) 

Species typical of drainages with dry washes or intermittent water are: 
. Mormon tea (Ephedra spp.) . Catclaw acacia (Acacia gregii) 
. Four-wing saltbush (Atriplex canescens) . Baccharis (Baccharis spp.) 
. Fremont cottonwood (Populus fremontii) . Snakeweed (Gutierrezia sarothrae) 
. Skunkbush (Rhus trilobata) . Apache plume (Fallugia paradoxa) 
  Red-bud (Cercis occidentalis) . Utah agave (Agave utahensis) 
Upland species, described below, are also present in these dry or intermittent washes. Trees and 
shrubs tend to be scattered, but may also form dense thickets. Species composition varies 
depending on moisture availability, elevation, and geographic location in the canyon. Within the 
park, tamarisk occurs in the many of the side canyon and tributaries; however, the distribution and 
density is highly variable. 
The vegetation surrounding the tributaries is generally from desert scrub communities, which are 
composed of plant species from three of the four North American desert floras. The Sonoran desert 
scrub has the highest diversity of species. A two-season rainfall regime and lack of freezing 
temperatures characterizes the Sonoran desert (Warren, et al. 1982). The Mojave desert scrub has 
higher local species diversity, but is primarily dominated by shrubs; it is characterized by winter 
rains and the absence of freezing temperatures (Warren, et al. 1982). The Great Basin desert 
receives more winter rain than the Mojave, and frequently has severe winter freezes and the lowest 
diversity of the three (Warren, et al. 1982). 
Big sagebrush (Artemisia tridentata), rabbitbrush (Chrysothamnus spp.), Mormon tea (Ephedra 
spp.) and a variety of perennial grasses dominate the Great Basin desert scrub. These associations 
are typically found in the lower portion of the canyon and comprise the vegetation surrounding 
some of the middle and lower tributaries. Typical Mojave desert species include blackbrush 
(Coleogyne ramosissima), turpentine broom (Thamnosma montana), bladder sage (Salazaria 
mexicana), and other species. The Sonoran desert species include brittle bush (Encelia farinosa), 
catclaw acacia (Acacia greggii), ocotillo (Fouquieria splendens) and desert willow (Chilopsis 
linearis). Sonoran associations occur in the lower portion of the canyons, and many of these species 
can grow directly in infrequently scoured drainages. 
Please refer to the next sections for the complete list of areas in which work crews completed work 
under this project. 
b. Dates, times and conditions under which work was completed 
Crews completed the tamarisk eradication work was completed in October and November 2002 and 
2003; trees are still actively transporting nutrients and water through the phloem and xylem during 
these months, and the insertion of herbicide into the tree yields effective control results. Crews 
completed one additional trip in March 2003, and the work provided good results. 

On each trip, the workdays were long, with coffee served between 6:00 and 6:30 a.m., and dinner 
often not ready until long after dark, yet once again, the participants enjoyed the project. Due to the 
remoteness of the terrain, it is necessary to access the majority of the project areas from the river. 
Each of the fall trips launched from Lees Ferry and took out at Diamond Creek. On each of the fall 
trips, there were 16 participants and 5 rafts, and on the March 2003 trip, there were 18 participants 
(including two archeologists) and 6 rafts. On each trip, there was an exchange at Phantom Ranch, 
and new, invigorated volunteers arrived to assist with the project while the upper half volunteers 
told horror stories about the long days and blisters. The dedication and perseverance of all of the 
crew members was amazing and contributed to the overall success of the project. The volunteers 
were crucial to the project accomplishments. Volunteers donated 1620 hours in October 2003 and 
959 in November 2003. The total hours spent on the two fall 2003 trips was 6149; therefore, 
volunteers supplied about 42% of the total hours in 2003. Please refer to Appendix D for complete 
project hour data for 2003.

The project leader prepared itineraries, reviewed and approved by park management, prior to each 
trip (please refer to Table 1 and Table 2 for the final itineraries for the trips). Poor weather 
conditions and additional time needed at specific sites necessitated alteration of the itinerary on 
several occasions. During all trips to date, there were a few days of rain. Many of the project areas 
are in narrow side canyons, which are subject to flash flooding. On rainy days, crews only worked 
in wide open canyons that would be safe during a flood event. On those days, crews did not use the 
cut stump method since the rain could cause herbicide runoff. The weather on the October 2003 
trip was remarkable, with rain only on the first day, causing the crews to pass by Soap Creek to 
make time on the river. During the November 2003 trip, the boatmen rowed the rafts down to 
Phantom empty since the project areas were all on the lower half of the river. The NPS provided a 
wildlife biologist for the upper half of the trip (as the NPS representative), and he was able to get 
raptor surveys completed during the 4 days of transit. The boatmen arrived on time, but regaled us 
with stories of the windiest river days they had ever seen. Two of the boatmen had blisters on their 
hands that were wide open and raw, yet, to these dedicated folks sawed tamarisk trees the next day.

Each fall river trip was 18 days long and consisted of 16 people, although the March 2003 trip 
had 18 people. The trip length allowed for sufficient time to access and work in canyons on the 
itinerary. The goal of the control work was to target 15 tributaries per trip, totally the 63 canyons 
over the 4 control trips during the project period. The October 2003 trip focused on canyons 
along the upper half of the river (Lees Ferry to Phantom Ranch) and the November 2003 trip 
focused on canyons along the lower half of the river, and participants hiked in to this trip at 
Phantom Ranch. Some project areas required repeated visits to complete the initial control of the 
entire tamarisk populations, and some of these areas still require additional work on the 
upcoming March 2004 trip (funded by the Grand Canyon National Park Foundation). 
After incorporation of public comments into the Environmental Assessment / Assessment of Effect 
(EA/AEF) document, which is required under the National Environmental Policy Act (NEPA) and 
the National Historic Preservation Act (NHPA), project managers selected the final control 
methods. For this project, staff use a combination of methods including mechanical, chemical, and 
cultural (i.e. seeding). The restoration biologist / project leader selected the methods for each 
project location based on site characteristics and weather conditions; a brief description of each 
method follows: 
Manual Removal 
This is the method used for seedlings (and sometimes larger trees) in washes, streambeds, and nonsensitive 
areas. Hand tools (i.e. picks, pulaskis, and shovels) are used to loosen the soil surrounding 
the larger plants and then the entire root system, or at least below the root crown, is removed. 
Garlon Lance Injection 
The lance injector is a three- to four-foot long tool with four chambers. Small herbicide capsules 
(approximately  long by  in diameter) are placed inside the chambers, the lance is placed 
against the trunk of the tree, and as the top of the lance is pushed, the chamber opens and a capsule 
is inserted into the tree. The trunks diameter determines the number of capsules inserted. 
Girdle Method (a.k.a. Hack and Squirt) 
With this method, crews use a hatchet, tree girdler, or hand saw to cut downward into the waterconducting 
tissue (phloem) of standing trees then apply the herbicide mixture directly into the cut 
with a hand-pressurized sprayer (and coarse spray nozzle). On larger trees, two or more cuts are 
necessary. 
Cut Stump Method 
Crews cut the tree trunks near ground level with handsaws and then spray with Garlon4 mixed with 
a penetrating oil (JLB oil) at a rate of 25% herbicide to 75% oil. The trees phloem absorbs the 
mixture and transports it to the roots, with quick application increasing the effectiveness. 
Pressurized hand sprayers allow precision herbicide application with minimum overspray or drift 
risk. Crews now extensively use this method along, and in combination with girdling, since the 
control results have been high. 

Basal Bark Application 
With this method, crews treat the entire stem with Garlon4 (same mixture as above) from near 
ground level up several inches. Crews apply the chemical with hand held pressurized sprayers, 
which have small nozzles with coarse spray settings that allow for direct spraying with minimal drift 
or overspray. This method is much less labor intensive, but is less effective on mature trees so 
limited use on smaller saplings and seedlings occurs. 
Mitigation Measures 
The following specific measures apply to all methods used for the project: 
 Debris is disposed of to minimize visual impact (i.e. off trail, out of the drainage). 
 Empty herbicide capsules are removed from trees in the year following treatment. 
 Cut stumps are hidden from view to the extent possible. 
 Soil is tamped where manual removal is used to help minimize establishment of other 
invasive exotic species and to minimize visual impact. 
 Tree cuts are made on tree sides least visible to backcountry users. 
 When pruning, a minimal number of branches are cut to minimize visual impact. 
Much of the debris remains on site to decompose and provide habitat for wildlife. Crews minimize 
the visual impacts of the project through carefully placed cuts and girdles and the combination of 
control methods employed at each project site. 
Herbicide Use 
The herbicide used for control was Garlon4 (triclopyr based), which is a general use herbicide, in a 
mixture of 25% Garlon4 and 75% JLB oil. Stainless steel sprayers, pressurized with bicycle pumps, 
are the application tool. 
Pesticide certification is not required for Garlon application; however, the park vegetation staff 
adopted the policy of having trained and certified application on site during application. During 
these trips, the project leader, all field crew leaders, and some of the volunteers had Arizona State 
pesticide certification. All project participants received herbicide orientation and training from the 
project leader. Project participants understood and abided by the established Personal Protective 
Equipment (PPE) requirements and rules outlined in the safety plan for the project. Rubber gloves, 
long sleeve shirts, long pants, and eye protection were part of the PPE necessary for this project. All 
project participants reviewed the job hazard analyses (JHAs) for exotic plant removal and herbicide 
application. 
Project participants followed all information and instructions on the herbicide label. All herbicide 
containers were leak- and spill resistant. All application equipment and chemicals were stored in 
sealed ammunition cans or large silver boxes during transport on rafts, and all storage containers 
had the product's specimen label and the Material Safety Data Sheet (MSDS) clearly displayed 
underneath a waterproof plastic sheet. The MSDS contains fire and explosive hazard data, 
environmental and disposal information, health hazard data, handling precautions, and first aid 
information. All trip participants reviewed the MSDS with the project leader and understood the 
first aid instructions described on the MSDS. One boat contained all herbicide and application 
equipment, herbicide containers, and PPE disposal containers, isolated from food and personal 
items. 
d. Analysis of methods and tests 
Although current scientific literature documents successful control methods for tamarisk, refinement 
to the methods occurred during the work in Grand Canyon. Please refer to Appendix A for 
examples of methods and sample photographs, and to the fall 2002 report for preliminary discussion 
of methods. 
Crews used the Garlon lance injection method in 2002. Some benefits are that it is safer for the 
applicators, since there is less likelihood of contact with herbicide, and rainy conditions do not 
preclude the use of this method. When crews revisited Clear Creek in March 2003, the injected 
trees were still alive. Crews removed the capsules, and cut the trees. During 2003, 75 mile canyon 
flash flooded hard, and during the fall revisit, some of the injected trees were not locatable and 
likely had washed down the canyon. This was a significant concern since crews could not retrieve 
the empty capsules. Overall, crews found that the control effectiveness was low with this method 
and did not use it in 2003. However, park staff will further test this method in a controlled and 
easily visited setting and make a final determination about future use. 
Crews used the hack and squirt method in 2002, but based on the control results and input from the 
Lake Mead EPMT on the March 2003 trip, project leaders altered the technique prior to 2003 and 
renamed it the girdle methods. Crews determined that it is necessary to cut into the outer bark 
(about  deep) all the way around the tree trunk, leaving no section uncut. The cut can be lower to 
the ground that initially planned. Another key to the success is but to also spray the tree trunk from 
the cut to the ground in addition to application into the cut. Crews still use this method on scattered 
individual trees, but it remains difficult to use as the sole method in dense stands. 
Crews now extensively use the cut stump method alone, and in combination with girdling, since the 
control results have been the highest. It is also easiest to retreat those areas. Crews did notice that 
on previously cut mature trees, the regrowth tended to be a basal cluster affectionately named an 
afro. The retreatment method for the afros was basal application and no additional cutting was 
necessary.

IV. Results 
a. Results of recent data collection 
 2nd Redbud Alcove (quick re-check) 
During the fall 2003 river trips, crews controlled 19572 tamarisk trees including 12596 seedlings, 
4854 saplings, and 2122 mature trees (Refer to Figure 1). The total tamarisk canopy cover removed 
from the project sites was 9991 square meters. During the March 2003 river trip, crews completed 
work in 14 project areas, removing 10800 tamarisk trees including 6549 seedlings, 3008 saplings 
and 1243 mature trees for a total canopy cover of 8868 sq. meters. 
On each trip and at each project site, the project leader analyzed the site and determined which 
control methods to use. Refer to Table 3 for complete control data for all of the project areas to 
date. Figure 2 summarized the methods used on all of the tamarisk control trips combined. 
The amount of herbicide used, a mixture of 75% JLB Oil to 25% Garlon 4, was surprisingly low 
during 2003. A total of 42.5 mixed gallons were used on the March, October and November 2003 
trips; this is equivalent to 10.62 gallons of Garlon4 concentrate and 31.97 gallons of JLB Oil. 
Crews completed at 68 project areas (Monument Spring, Salt Creek Spring, and Ledges Spring are 
listed as separate sites in the data), a few of which are not on the AWPF list and were done in 
addition to the 63 on the list. These are Upper Redbud, Saddle Canyon, 91 Mile Canyon (R), 105 
Mile Canyon (R), and Mohawk Canyon. 
Crews completed follow-up control work in many areas, yet in several areas, the work required 
much more labor than predicted. The following sites, due to extensive populations, weather, or lack 
of time, will require additional visits and control implementation, scheduled for March 2004: 
 Fossil Canyon 
 128 Mile Creek 
 Bedrock Canyon 
 142 Mile Springs 
 Kwagunt Creek 
 Carbon Creek 
 75 Mile Creek (quick re-check) 
 Monument Creek 
 94 Mile Creek (1 small patch remains) 
 Boucher Creek 
 Tuna Creek 
Work has not yet begun at the following project sites: 
 Lower Bright Angel Creek  South Bass Canyon 
 Pipe Creek  133 Mile Creek 
 Hermit Creek  150 Mile Canyon 
We anticipate that crews will initiate work in these sites in February 2004. The 133 Mile Creek and 
150 Mile Canyon sites are only accessible from the river and are included in the itinerary for March 
2004 Colorado River Fund trip. Crews will access the other areas listed above, and Mounment 
Creek, by hiking. 
A large component of this project is the long-term monitoring, included with the control work. 
On the first river trip (October 2000), participants installed the majority of the monitoring 
components. The components include vegetation transects and photopoints. On the fall 2002 
and 2003 trips, crews installed photopoints in additional project areas. Please refer to the 
monitoring plan for the overall design and implementation scheme. Appendix B contains 
representative samples of the photodocumentation and Appendix C includes the summary data 
for all installed photopoints for the project. The compact disk included with this report also 
contains all of the photographs taken for this project to date, organized by project area and date 
taken. The disk also included photographs of the crews working and examples of the various 
techniques used.

V. Discussion and Conclusions 
a. Discussions and conclusions about results comparing current, and past control 
results 
After working with the professional EPMT crew from Lake Mead, project crews realized that they 
were applying an insufficient amount of herbicide to the cut stumps, and increased the amount used. 
This explains some of the high rates of retreatment necessary in 2003. Overall, crews have only 
retreated 6.33% of the total number of tamarisk initially treated (refer to Figure 3 and Table 4). 
However, upon removal of the large seedling component from the data summaries, 11.9% of the 
saplings and 25.2% of the mature trees controlled in 2002 were retreated in 2003. Project leaders 
feel that project success rates will be much higher in the future with the implemented changes. The 
final monitoring trip will be from May 26 through June 14, 2004; the subsequent final report for this 
project will contain control conclusions and discussion. 
b. Discussion and conclusions about results with relation to related literature. 
This report contains the control data from the control trips to date and information about preliminary 
project results. The final monitoring trip will be from May 26 through June 14, 2004; the 
subsequent final report for this project will contain control conclusions and discussion. 
VI. Management Recommendations 
a. Overview of management options. 
During the implementation of this project, crews implemented tamarisk control methods in 68 areas 
within GCNP. The monitoring results of this project will help further refine the control methods 
and management options. The National Park Service has an affirmative responsibility to protect and 
preserve the resources located within its units. National Park Service (NPS) Management Policies 
require park managers to maintain all the components and processes of naturally evolving park 
ecosystems, including the natural abundance, diversity, and genetic and ecological integrity of the 
plant and animal species native to those ecosystems (NPS 2001b). Park managers are directed to 
give high priority to the control and management of exotic species that can be easily managed and 
have substantial impacts on the Parks resources (NPS 1985, NPS 2001b). 
This project has verified that the control of tamarisk in the parks side canyons and tributaries is 
indeed feasible. A vast body of literature documents the impacts that tamarisk has on southwestern 
ecosystems, and Stevens (2001) summarized the impacts and ecology of the species. Since the 
control is feasible and tamarisk posed a substantial impact on the resources located within GCNP, 
the continuation of this project to include the other phases should occur. Park management have 
been supportive of this project, and with continued documentation and successful implementation, 
the support should remain strong. 
b. Management recommendations and justification. 
The EA/AEF for this overall project included three phases of tamarisk management and tributary 
restoration. The work completed under this contract is Phase I of the overall project. The first five 
control trips were very successful and crews worked out the overall logistics of the project and 
transportation to project sites, and can now more accurately plan trip itineraries. The final 
monitoring trip will be in the spring of 2004. Project leaders anticipate that the control methods will 
lead to successful management of tamarisk populations in the project areas. Park staff are seeking 
additional funding for Phase II and Phase III of the project, and this valuable work should be 
continued. The EA/AEF for this project states that the park will commit to the follow up control 
necessary for Phase I project sites, and project leaders recommend integration of this project into the 
overall resource and vegetation management plans. 
After completion of the final monitoring trip, project leaders should prepare articles for both internal 
NPS publications and peer-reviewed journals. The AWPF funding and flexibility with project 
implementation has been essential to getting this project off the ground, and protecting and restoring 
the parks valuable riparian ecosystems. The partnership between GCNP and the GCWC has also 
been integral to the success of the project. The primary recommendation at this point is to continue 
the work, and to expand the project to include all of the tamarisk populations in the side canyons 
and tributaries of the park.
