<strong>Project</strong> <strong>Level</strong> <strong>Watershed</strong> <strong>Analysis</strong><br />

<strong>McBride</strong> <strong>Springs</strong> <strong>Campground</strong> Diseased Trees Removal<br />

<strong>Project</strong><br />

Shasta-McCloud Management Unit<br />

Shasta-Trinity National Forest<br />

Prepared by Heidi George - Hydrologist<br />

Introduction<br />

<strong>Watershed</strong> analysis is expected to yield the contextual information needed to define ecologically<br />

and geomorphically appropriate Riparian Reserves. <strong>Analysis</strong> of site-specific characteristics may<br />

warrant Riparian Reserves that are narrower or wider than the prescribed widths. Thus, it is<br />

possible to meet the objectives of at least the Aquatic Conservation Strategy portion of these<br />

standards and guidelines with post-watershed analysis reserve boundaries for intermittent streams<br />

that are quite different from those conforming to the prescribed widths. Regardless of stream type,<br />

changes to Riparian Reserves must be based on scientifically sound reasoning, and be fully<br />

justified and documented. 1<br />

This <strong>Project</strong> <strong>Level</strong> <strong>Watershed</strong> <strong>Analysis</strong> characterizes the <strong>McBride</strong> <strong>Springs</strong> watershed and<br />

identifies the Desired Future Condition (DFC) for Riparian Reserves to facilitate planning<br />

for the <strong>McBride</strong> <strong>Springs</strong> <strong>Campground</strong> Diseased Trees Removal <strong>Project</strong> (hereinafter<br />

referred to as <strong>Project</strong>). Because this is a project-level watershed analysis it only includes<br />

identifying issues or key questions that are related to the <strong>Project</strong>. While restricted to project<br />

relevant issues or key questions, this analysis does provide an overview of the physical,<br />

biological and human features within public lands in the entire <strong>McBride</strong> <strong>Springs</strong> watershed<br />

and the context of this project within this watershed.<br />

The proposed action for the <strong>Project</strong> is to cut and remove hazardous and diseased trees from<br />

the campground:<br />

1. Immediate hazard tree removal.<br />

The material from the cut trees will be removed from the site or stacked as<br />

firewood for use by campers. Other debris will be chipped and spread on the site,<br />

piled, or piled and burned.<br />

2. Protection and Mitigation Measures including Best Management Practices.<br />

The forest plan for the Shasta-Trinity National Forest allows for falling hazardous trees in<br />

campgrounds within riparian areas when they pose a safety risk. Further direction includes<br />

keeping felled trees on-site when needed to meet coarse woody debris objectives<br />

(LRMP 4-58, 8.b).<br />

<strong>Project</strong> <strong>Level</strong> <strong>Watershed</strong> <strong>Analysis</strong> Description<br />

A project level watershed analysis (PLWA) is deemed necessary for the <strong>Project</strong> because in<br />

order to remove hazard trees it will be necessary to enter the <strong>McBride</strong> <strong>Springs</strong> intermittent<br />

riparian reserves in the absence of a comprehensive basin-scale (5 th field ) watershed<br />

analysis. This PLWA will focus on how the proposed activity could affect attaining<br />

Aquatic Conservation Strategy Objectives as required by the forest plan.<br />

The format for this PLWA follows the same organization as that used to analyze a basinscale<br />

watershed, while excluding analysis on anything not directly related to the project 8 th<br />

field HUC.<br />

3. Description of current condition.<br />

4. Description of reference conditions.<br />

5. Synthesis and Interpretation of Information.<br />

6. Recommendations.<br />

The information in Chapters 1, 3, 4 and 5 is needed to assess the issue within the context of<br />

the physical and biological features, biological processes and human uses in the watershed.<br />

Information in Chapters 2 and 6 is mostly limited to issue recommendations.<br />

Chapter 1: <strong>Project</strong> and <strong>Watershed</strong> Characterization<br />

Chapter 1 briefly characterizes the <strong>Project</strong> area and its relationship to the PLWA area.<br />

Public lands within the <strong>McBride</strong> <strong>Springs</strong> 7 th field watershed are managed under the Mount<br />

Shasta Management Area direction. 2 The management area is 69,282 acres, much larger<br />

than the <strong>McBride</strong> <strong>Springs</strong> watershed (7,803 acres), and is composed of Matrix Prescription<br />

III Roaded Recreation (91%), with the remaining managed for Riparian Reserves and<br />

Heritage Resource Protection as follows:<br />

Desired Future Condition:<br />

The Mount Shasta Management Area is managed<br />

predominantly for Cultural and historic values, visual<br />

quality and recreational values. The forest plan notes that<br />

“With the exception of developed campgrounds, Forest<br />

Service facilities are meeting visitor demand. This need<br />

is balanced by campground facilities in the private<br />

sector.”<br />

Vegetation management activities are consistent with the<br />

above mentioned values in this Management Area.<br />

Riparian Reserves are applied along both sides of rivers,<br />

stream, lakes and wetlands. Riparian Reserves appear as<br />

natural corridors throughout the Matrix. 3<br />

Management activities are evident but subordinate to the<br />

viewer within this area.<br />

Supplemental Management Direction includes:<br />

“Manage for a high level of water quality of important domestic<br />

water sources at …<strong>McBride</strong> <strong>Springs</strong>…” 4<br />

Water samples are taken at all developed recreation sites on the forest and<br />

sent to a water quality laboratory for analysis and approval for culinary use<br />

prior to opening the campground for the public. 5<br />

The upper two-thirds of the watershed is public land while the lower third includes the city<br />

of Mount Shasta and private land ownership. General characteristics for the project and<br />

Hydrologic Location: <strong>McBride</strong> <strong>Campground</strong> lies on the western flanks of Mount<br />

Shasta within a 7 th field hydrologic unit, <strong>McBride</strong> <strong>Springs</strong> (18020005010302). The<br />

<strong>McBride</strong> <strong>Springs</strong> watershed is tributary to Cascade Gulch-Mount Shasta (6 th field), Box<br />

Canyon (5 th field) and Sacramento Headwaters (4 th field) hydrologic units.<br />

The scale selected for this PLWA is based on the smallest watershed that has readily<br />

available information that addresses the proposed activity. <strong>Analysis</strong> of a larger watershed<br />

may not detect any effects from the proposed activities; analysis of a watershed area<br />

smaller than the 8th field HUC may magnify any effects.<br />

Chapter 2: Issues and Key Questions<br />

Issue:<br />

Effects of the proposed activities on riparian habitat and Aquatic Conservation Strategy<br />

objectives.<br />

Key Questions:<br />

Are the proposed activities consistent with the Aquatic Conservation Strategy (ACS)<br />

objectives? How will proposed activities affect the Aquatic Conservation Strategy and the<br />

condition of Riparian Reserves in the analysis watershed? How will the activities proposed<br />

in and adjacent to the <strong>McBride</strong> <strong>Springs</strong> Riparian Reserve affect habitat in the Riparian<br />

Reserves at this site?<br />

Chapter 3: Current Conditions<br />

The purpose of Chapter 3 is to provide a general description of current conditions for<br />

aquatic, terrestrial and human uses in the project area. Only information relevant to the<br />

issues and key questions is presented.<br />

Climate


The project area is located in the extreme northern end of the Mediterranean Highland<br />

Climate Region and is characterized by warm dry summers and cool wet winters. Annual<br />

precipitation in the project area is estimated to be approximately 66 inches with the<br />

majority of this precipitation falling as snow. Additionally, Mt. Shasta provides a strong<br />

orographic influence upon storms approaching from the southeast and creates a deeper<br />

snowpack in the vicinity. Thunderstorms produce occasional summer precipitation events.<br />

The project area lies between 4,480 and 5000 feet in elevation with south-westerly aspect.<br />

A disturbance climatic regime is strongly influenced by the location of the project on the<br />

flanks of Mount Shasta at 14,179 feet summit elevation.<br />

Geology and Geomorphology<br />

Mount Shasta is a stratovolcano with a history of eruptive episodes of lava and pyroclastic<br />

flows. Individual lava flows stand out as buttes on the more gentle flanks of Mount Shasta<br />

immediately above the project area and form the steep ridges in the watershed analysis<br />

area. Deposits of glacial outwash material lie on and adjacent to rock outcrops and fill the<br />

very steep drainages. The dominant processes occurring today within the watershed that<br />

affect the human environment include rockfall, debris flow and avalanches. The history of<br />

debris flow in the 7th field watershed is recent: in 1997 a rain on snow event, with a 100<br />

year recurrence interval, initiated a debris flow in the drainage east of Cascade Gulch<br />

activating 2.5 miles of glacial outwash material that reached the city limits.<br />

Hydrology and Riparian Reserves<br />

<strong>Springs</strong> and channels occur in the project area and flow intermittently. Although snowmelt<br />

and groundwater recharge occurs earlier in the spring, groundwater activates the springs<br />

and flow occurs in the summer. During these periods of surface flow, soils become<br />

saturated and overland flow occurs below the springs and upslope of the campsites making<br />

some campsites unsuitable for camping.<br />

Small drainage ditches can be seen upslope of several campsites from past efforts to<br />

control and intercept overland flow before reaching individual campsites. The current<br />

management practice is to protect soils by closing wet campsites until they dry out.<br />

The riparian reserve within the <strong>McBride</strong> <strong>Springs</strong> <strong>Campground</strong> project area maintains<br />

facultative and obligate riparian vegetation with limited water from the spring source and<br />

short duration flow in the intermittent stream. The intermittent stream carries annual<br />

surface water from the spring down slope through the campground and downstream of the<br />

project area. This occurs primarily in the months of July and August when snowmelt<br />

recharges the groundwater and allows surface flow to occur. It is not known how far this<br />

flow continues down slope; however there is evidence of scouring due to runoff in the road<br />

crossings of Cascade Gulch. The intermittent stream stemming from <strong>McBride</strong> <strong>Springs</strong> is<br />

the only known intermittent stream that conveys this annual water in the upper reaches of<br />

this watershed or supports riparian vegetation.<br />

Most of the intermittent streams in the watershed have such high infiltration that they<br />

infrequently convey water; when they do they function to maintain important connectivity<br />

for terrestrial and aquatic organisms. Other intermittent streams function to deliver large<br />

sediment loads to the reaches at lower elevations and have no riparian vegetation<br />

associated with them. Maintaining the integrity of these channel features is important to<br />

<strong>Project</strong> <strong>Level</strong> <strong>Watershed</strong> <strong>Analysis</strong> <strong>McBride</strong> <strong>Springs</strong> <strong>Campground</strong> Diseased Trees Removal <strong>Project</strong>


maintaining hillslope processes, such as existing natural erosion rates, without accelerating<br />

them.<br />

Episodic flood events are responsible for the large debris flow channels that characterize<br />

the larger drainages. Water flows in these channels in response to snowmelt conditions and<br />

occasional rainfall. Debris flows are associated with these channels, for example, Cascade<br />

Gulch, and carry rock, water and sediment from higher elevations in narrow deep canyons<br />

to lower elevations where sediment is deposited on debris fans that splay out across a wide<br />

swath. Riparian reserves associated with these types of intermittent streams are subject to<br />

large-scale natural disturbance from debris flows as well as avalanches.<br />

Vegetation<br />

Very limited aquatic, riparian and meadow habitats are present within and adjacent to the<br />

<strong>Project</strong>. White fir, ponderosa pine and cedar dominate the overstory vegetation in the<br />

project area. The understory is comprised of a diverse riparian plant community, including<br />

willow providing subdominant plant community structure and many forbs and grasses in<br />

the understory near the ground. Mature willow reaches upwards of twenty feet in height<br />

where some sunlight is able to reach the forest floor. This vegetation provides root strength<br />

to the streambanks which qare in a highly functional condition. The vegetation influenced<br />

by the springs and extended periods of wetting adjacent to the intermittent channel<br />

includes obligate and facultative plants associated with wet soils.<br />

Recreation<br />

The <strong>McBride</strong> <strong>Springs</strong> <strong>Campground</strong> provides opportunities for developed camping, and<br />

is utilized primarily during summer. Users enjoy camping, picnicking, and hiking<br />

along the campground trails.<br />

<strong>McBride</strong> has 11 campsites that are usually full during camping season.<br />

With the current situation from campground closure, users have had to camp at either<br />

Panther Meadows or Bunny Flats. This has caused campers to adjust their plans<br />

accordingly, placing extra pressure on these already well-utilized sites since the<br />

campground was closed for safety reasons.<br />

The campground is closed in the fall, winterized and opened in the spring as conditions<br />

allow.<br />

Equivalent Roaded Area and Soils<br />

The project area is approximately ten acres, approximately 0.1 percent of the 7,803 acre<br />

7th field hydrologic unit. The threshold of concern for the <strong>McBride</strong> <strong>Springs</strong> hydrologic<br />

unit is adopted from the larger 5 th field Box Canyon <strong>Watershed</strong> which has a threshold of<br />

concern equivalent roaded area of 18%.<br />

The current ERA for the <strong>McBride</strong> <strong>Springs</strong> hydrologic unit is 3.4% primarily from roads.<br />

A large portion of the lower portion of the watershed is urban and urban interface. The<br />

upper watershed is mixed-conifer with manzanita and ceanothus brushfields.<br />

Approximately half of the upper watershed upslope of the urban area is in plantations.<br />

Timber harvest activity from the Mountain Thin and Fuels Management <strong>Project</strong> is<br />

ongoing. No recent fires have occurred in the watershed.<br />

Chapter 4: Reference Conditions<br />

The purpose of Chapter 4 is to focus in on the historical activities that have affected<br />

watershed condition and are relevant to the proposed project.<br />

Historical accounts were made by visitors traveling as early as 1854. 6 First ascents of<br />

Mount Shasta describe the vegetation from the lower elevations near the City of Mount<br />

Shasta, up Cascade Gulch and continuing beyond <strong>McBride</strong> <strong>Springs</strong>. From these accounts,<br />

the vegetation is described as being expansive and impenetrable shrub fields interrupting<br />

large stands of sugar pine and ponderosa pine, with little understory.<br />

“Our road lay through dark heavy forest of pine, cedar, fir, and thickets of<br />

underbrush which were, in places, almost impenetrable… An hour and a<br />

half’s ride brought us to Cedar Seat Camp – a cozy little retreat hid away in<br />

the “deep tangled wildwood” by a little mountain rivulet of sparkling water<br />

which coursed its way from the frozen snows of Mount Shasta.” Source –<br />

Fires were regularly observed during 1854 to 1884 according to these historical accounts,<br />

with smoke or haze from forest fires annually obscuring the sky after July until the fall<br />

rains. After 1886 fires and timber cutting, forested stands were recorded as being replaced<br />

by extensive brush fields.<br />

The 8th field watershed (2,642 acres) that surrounds the <strong>McBride</strong> <strong>Springs</strong> <strong>Campground</strong><br />

project area has had road construction since the early 1900’s. Trails followed by roads<br />

with narrow widths were replaced with paving and proper road drainage. Road access on<br />

the Everitt Memorial Highway has always been dependent on the snow conditions and are<br />

usually plowed to keep the road open for recreation beyond <strong>McBride</strong> <strong>Springs</strong> at Bunny<br />

Flat. Road closure due to abundant snow can sometimes keep the roads closed from<br />

December until late May. The <strong>McBride</strong> <strong>Springs</strong> <strong>Campground</strong> is typically gated closed in<br />

October, opening when ground conditions and maintenance allow.<br />

Chapter 5: Interpretations<br />

Chapter 5 of this analysis addresses the key question for the proposed project.<br />

The Effects of Proposed Management Activities in Riparian Reserves:<br />

The proposed <strong>McBride</strong> <strong>Springs</strong> <strong>Campground</strong> Diseased Trees Removal <strong>Project</strong> is consistent<br />

with the ACS objectives. On a watershed scale, activities from the implementation of the<br />

<strong>Project</strong> are expected to be negligible and unmeasurable. On a project scale, because<br />

activities are proposed for Riparian Reserves the proposed project may have a temporary<br />

effect from minimal ground disturbance on the existing hydrologic processes and function<br />

within the reserve. No effects from the project are anticipated outside of the campground<br />

boundary.<br />

Very wet periods such as rain on snow events allows surface water to flow in the<br />

intermittent channels in the campground and sometimes throughout the watershed as well<br />

as in the steep drainages that parallel the project area. These events are more episodic in<br />

nature and may produce debris flows in the drainages that have reached the alluvial fan<br />

upslope of the City of Mount Shasta. This is a natural geomorphic process that is not<br />

affected by the project.<br />

<strong>Project</strong> <strong>Level</strong> <strong>Watershed</strong> <strong>Analysis</strong> <strong>McBride</strong> <strong>Springs</strong> <strong>Campground</strong> Diseased Trees Removal <strong>Project</strong>


Light campground recreational activities associated with camping, walking on the short<br />

trails, and campsite maintenance such as clearing winter debris from paved roads and<br />

campsites occur near and within the campground. Soils are saturated each year below the<br />

springs and ditches that were constructed to divert surface flow away from campsites<br />

interupt wetland function. Closing campsites due to wet soils eliminates camping<br />

opportunites at the campground, and as the ditches are still somewhat functional reduces<br />

connectivity of the hillslope to the intermittent channels. This situation does not occur<br />

elsewhere in the watershed and is limited to the <strong>McBride</strong> <strong>Campground</strong>.<br />

Landings are required to stage the large logs and any biomass. Potential landings were<br />

identified in the field and were located in existing openings outside of the riparian area in<br />

uplands surrounded by upland vegetation. Such minimal ground disturbance is not<br />

expected to disrupt forest soil building processes and should be difficult to detect after<br />

several seasons of litter-fall and snowfall.<br />

A description of how the project will or may affect each ACS objective is presented in<br />

Table 2.<br />

Table 2: Effects of Proposed Activities on ACS Objectives.<br />

Aquatic Conservation Strategy Objectives Effects of Proposed Management Activity<br />

1. Maintain and restore the distribution, diversity, and<br />

complexity of watershed and landscape-scale features to<br />

ensure protection of the aquatic systems to which species,<br />

populations and communities are uniquely adapted.<br />

2. Maintain and restore spatial and temporal connectivity<br />

within and between watersheds. Lateral, longitudinal, and<br />

drainage network connections include floodplains,<br />

wetlands, upslope areas, headwater tributaries, and intact<br />

refugia. These network connections must provide<br />

chemically and physically unobstructed routes to areas<br />

critical for fulfilling life history requirements of aquatic<br />

and riparian-dependent species.<br />

3. Maintain and restore the physical integrity of the<br />

aquatic system, including shorelines, banks, and bottom<br />

configurations.<br />

4. Maintain and restore water quality necessary to support<br />

healthy riparian, aquatic, and wetland ecosystems. Water<br />

quality must remain within the range that maintains the<br />

biological, physical, and chemical integrity of the system<br />

and benefits survival, growth, reproduction, and migration<br />

of individual composing aquatic and riparian<br />

communities.<br />

5. Maintain and restore the sediment regime under which<br />

aquatic ecosystems evolved. Elements of the sediment<br />

regime include the timing, volume, rate, and character of<br />

sediment input, storage, and transport.<br />

6. Maintain and restore instream flows sufficient to create<br />

and sustain riparian, aquatic, and wetland habitats and to<br />

retain patterns of sediment, nutrient, and wood routing.<br />

By removing the hazard trees in the campground, the<br />

distribution, diversity and complexity of the watershed<br />

will be maintained and incrementally improved as more<br />

light will benefit riparian vegetation vigor.<br />

The proposed action will maintain spatial and temporal<br />

connectivity of meadow habitats within the <strong>McBride</strong><br />

<strong>Springs</strong> <strong>Campground</strong>.<br />

The proposed action will have an overall neutral effect on<br />

the physical integrity of the aquatic system. Some short<br />

term negative impacts could occur due to removal of<br />

vegetation in near streamside areas, however these<br />

impacts are expected to be offset by improved vigor of the<br />

riparian vegetation.<br />

The proposed action will have a neutral effect on water<br />

quality. Best management practices and resource<br />

protection measures will be in place to avoid impacts to<br />

water quality from the activity.<br />

The proposed action will have a neutral effect on the<br />

sediment regime. Slopes within the riparian reserve are<br />

primarily less than 2% with steeper slopes approaching<br />

10% primarily outside of the proposed action activity.<br />

The potential for runoff from the surrounding slopes into<br />

the intermittent creek is low.<br />

The removal of conifers may reduce evapotranspiration<br />

enough to have a limited, albeit immeasurable, increase in<br />

duration and volume of instream flows in the intermittent<br />

The timing, magnitude, duration, and spatial distribution<br />

of peak, high and low flows must be protected.<br />

7. Maintain and restore the timing, variability, and<br />

duration of floodplain inundation and water table<br />

elevation in meadows and wetlands.<br />

8. Maintain and restore the species composition and<br />

structural diversity of plant communities in riparian areas<br />

and wetlands to provide adequate summer and winter<br />

thermal regulation, nutrient filtering, appropriate rates of<br />

surface erosion, bank erosion, and channel migration and<br />

to supply amounts and distributions of coarse woody<br />

debris sufficient to sustain physical complexity and<br />

stability.<br />

9. Maintain and restore habitat to support well-distributed<br />

populations of native plant, invertebrate, and vertebrate<br />

riparian-dependent species.<br />

Chapter 6: Recommendations<br />

channel and because of the small scale of the project, are<br />

expected to occur for a very limited duration.<br />

The removal of conifers could have a small effect on the<br />

timing, variability, and duration of floodplain inundation<br />

within the project area. It is also possible that the conifer<br />

removal could have a more sustained effect on the<br />

meadow hydrology by raising water table levels during<br />

periods of runoff.<br />

Removal of conifers will maintain the small meadow<br />

habitats and stream-side riparian vegetation. Mature<br />

willow provides abundant woody debris recruitment for<br />

maintaining channel structure.<br />

The proposed action will have a positive effect in<br />

maintaining and restoring habitat to support populations of<br />

native plant, invertebrate, and vertebrate ripariandependent<br />

species.<br />

Appropriate management activities for Riparian Reserves include those activities that<br />

restore and preserve Riparian Reserves, are consistent with the Aquatic Conservation<br />

Strategy and move the reserves towards a Desired Future Condition.<br />

Plan and implement vegetation management activities that restore and/or preserve the<br />

aquatic, riparian and meadow habitats unique to the <strong>McBride</strong> <strong>Springs</strong> landscape.<br />

Manage Riparian Reserves to meet Aquatic Conservation Strategy Objectives and to<br />

move Reserves towards desired future conditions. 8<br />

No adjustments to the Riparian Reserve widths are recommended from this <strong>McBride</strong><br />

<strong>Springs</strong> PLWA.<br />

To harvest the true fir hosts of the annosus disease, heavy equipment is required to<br />

enter the riparian reserves at the <strong>McBride</strong> <strong>Springs</strong> <strong>Campground</strong>. To protect the<br />

immediate floodplains and banks of the channels and springs, an Equipment Exclusion<br />

Zone (EEZ) should be designated.<br />

Twenty feet out from any spring, intermittent stream or ditch except for stream<br />

crossings a 20 foot EEZ, measured from the channel banks outward on each side, will<br />

be designed to avoid impacts to hydrologic and riparian vegetative features. 9<br />

No ground disturbance within this zone should occur from equipment capable of<br />

reaching in from outside the zone. Where this is not possible, as in the stream<br />

crossings, minimal ground disturbance may occur within the EEZ where directional<br />

hand-falling conifer requires the log to be dragged out by a grapple line attached to<br />

heavy equipment such as a skidder.<br />

Examples of management activities that are consistent with the desired future condtion<br />

include camping, commercial or noncommercial harvest of diseased and disease-prone<br />

conifers, prescribed or natural fire, and returning slopes to near-original contours<br />

disturbed from past flood control efforts.<br />

Improving connectivity of surface water within the campground by returning hillslopes<br />

to pre-drainage contours is recommended.<br />

During development of the project specific watershed analysis it was found that<br />

campground users have been displaced during the <strong>McBride</strong> campground safety<br />

closures. A comprehensive watershed analysis would evaluate the use at the alternative<br />

sites that campers chose to go to and address issues and opportunities found there.<br />

Conduct a comprehensive <strong>Watershed</strong> <strong>Analysis</strong> for the Shasta SW Planning <strong>Watershed</strong><br />

within the Box Canyon <strong>Watershed</strong> (HUC 5).<br />

Plan and implement management activities to reduce impacts to meadow, aquatic and<br />

riparian habitats camping use at <strong>McBride</strong> <strong>Springs</strong> <strong>Campground</strong>.<br />

Evaluate potential for completing a basin scale <strong>Watershed</strong> <strong>Analysis</strong> and a<br />

comprehensive Roads <strong>Analysis</strong> for the Mount Shasta <strong>Watershed</strong>s. Not having these<br />

<strong>Watershed</strong> and Roads Analyses greatly limits opportunities for doing beneficial<br />

projects in some Riparian Reserves. With these analyses, restoration opportunities,<br />

including road decommissioning and restoration projects in Riparian Reserves, are<br />

more fully considered within a watershed context.<br />
