Using new tools, The Freshwater Trust calculates the ecological uplift of restoration projects and communicates the value of our work. Uplift = the quantifiable environmental gain of a project. For example, when we plant trees next to a stream for shade benefit, we calculate the solar load avoided. When we plant the trees for nutrient reduction, we calculate the change in pounds of nitrogen and phosphorus runoff.

Quantifying Ecological Uplift: Why it is Important

T
he Freshwater Trust is a non-profit organization with a mission to preserve and restore
freshwater ecosystems. With nearly 30 years of on-the-ground experience, we have always
looked for innovative ways to fix imperiled rivers and streams.
Hanmi Meyer
What do we mean by ecological uplift? Simply put, “uplift”
refers to the environmental gain of a project — the quantifiable
environmental benefit of the restoration actions we take.
For example, when we plant trees next to a stream, we can
now model the solar radiation that will be blocked by mature
trees and calculate kilocalories per day of solar load avoided.
How do we reflect that in our analysis and reporting of our
projects? First, let’s look at how we might have reported a tree
planting project in the past:
Healthy and functioning
habitat is critical to improving
wild fish populations.
Example from the past: planting project without uplift metricS

Tracking the number of trees planted does not measure or

Quantifying the benefits of restoration
projects in this way can provide a
more robust picture of a project’s
value. In fact, we are now doing
these calculations on projects before
implementation to determine potential
ecological uplift prior to committing
significant resources to a project. We are
doing this to ensure we apply resources
to project sites and restoration actions
that achieve the most benefit.
Measuring the width
of a stream is an important
factor in determining baseline
habitat conditions.
In the future, this new ability to quantify
project benefits can aid conservation groups and funders in better directing grant dollars and other
environmental investments. Traditionally, grant seekers like The Freshwater Trust — submit
—
project proposals to grant makers that describe the actions to be taken, the cost to implement and
a general rationale for why the project is needed. This method makes it challenging to distinguish
between similar projects in a competitive environment where the need is great and the funding is
limited. Using the scientific tools described in this report, we imagine that conservationists will be
able to estimate ecological uplift for projects and improve rationales for project location and design.
Sean O’Connor, Freesolo Collective
Like all groups in this field, The Freshwater Trust has traditionally evaluated and reported
on projects in terms of dollars spent, trees planted, gallons of water restored instream or acres
of floodplain reconnected, etc. In 2012, our approach is evolving, just like the science we use to
measure ecological benefit. Using recently developed — and
in some cases, still developing — tools for calculating the
ecological uplift of restoration projects, we are advancing a
new system for communicating the value of our work.
Uplift from 2012 Projects...........................................................................................................................................10
We have quantified most of our work in 2012 with regard to ecological uplift. We are committed to
doing this every year so that we may begin to understand and evaluate the actual effectiveness of
our actions and their benefits to our rivers and streams.
The Freshwater Trust measured and quantified the ecological uplift of its projects
with powerful tools, built using the best thinking and data available to the various developers and
partners. That said, the underlying science and modeling methods remain iterative. Over time,
as The Freshwater Trust and others use these tools to evaluate project benefits, the monitoring
of ongoing project performance will provide an essential feedback loop for refining the formulas,
calculation methodologies and modeling logic used by the tools. In this way, not only will uplift
calculation continue to improve, but so will restoration practices, project design and our general
understanding of aquatic ecosystem functions.

T
he Salmon Calculator is designed to quantify ecological changes that directly impact
salmon habitat. The Salmon Calculator helps us model, on average, how well a given
stream reach supports salmon. Put a different way, the Salmon Calculator uses data
from a given reach of stream (say 1,000 feet long), and weights the number of feet that
demonstrate ideal habitat function. If 10% of a 1,000 foot reach is optimal, then that reach receives
a score of 100 weighted linear feet. Change is calculated as the difference between pre-project
conditions (baseline) and modeled conditions 20 years after project work.
Aquatic features such as
log jams, pools, riffles,
glides, alcoves, gravel bars &
cascades
Inputs into the Salmon Calculator are physical characteristics of the stream and terrestrial
areas (see sidebar for model inputs). Based on the inputs, the Salmon Calculator measures the
ecological functions of a stream with regard to its ability to create and maintain salmon habitat. The
Salmon Calculator then consolidates those ecological functions into one salmon habitat score.
The score is a percentage of functional habitat per linear foot of stream, which is recorded as
weighted linear feet.

The Salmon Calculator was developed as part of Counting

Shade-a-lator is a module of Heat Source, a stream assessment tool used by Oregon Department
of Environmental Quality (ODEQ). It was developed in 1996 as a Master’s Thesis at Oregon
State University in
the Departments of
Bioresource Engineering
and Civil Engineering.
ODEQ currently
maintains the Heat

Using pre-project data (see sidebar for model inputs), Shade-a-lator calculates the current
amount of solar radiation hitting the surface area of a stream. Once vegetation is planted,
Shade-a-lator models the amount of solar radiation hitting the stream based on the new vegetation’s
maturity. The difference represents that project’s uplift in terms of solar radiation blocked or avoided
by streamside shade. Shade-a-lator expresses this uplift in energy units of kilocalories per day.

iparian shade, provided by streamside trees, blocks the sun’s rays from hitting the surface
of the water, reducing the amount of energy entering the river. In effect, this shade prevents
the water from heating up. Anadromous fish, such as salmon and steelhead, are extremely
sensitive to water temperature. Healthy riparian buffers help ensure healthy fish habitat.

ncreasing flow can buffer water temperature and increase velocity through a stream reach.
This can limit the water’s exposure to the local temperature to keep the water from warming.
Additional temperature benefits can be achieved if the increased flow is cooler than water in
the existing stream reach.

The Water Temperature Transaction Tool (W3T) uses river and landscape characteristics to

tributary inputs and meteorological information. From these inputs, W3T calculates temperature
changes in a river reach.

Tributary inputs
W3T is based on a steady flow approach requiring baseline data (see sidebar for model inputs); W3T
models water temperature based on energy transfer to and from the water across the air-water
interface and bed-water interface. It
also accounts for transport of heat
energy in the downstream direction.
River velocity

Water temperature reduction from
increased flow can be determined
by comparing baseline conditions
with modeled conditions after flow
has been restored. The difference in
water temperature represents the
temperature uplift from restoring
flow to that reach.

Large sediment loads that carry these nutrients can also harm aquatic systems. They can settle
into streambeds and fill in the spaces between the rocks and gravel — spaces that are essential for
salmonid spawning. Sediment-filled streambeds also cut streams off from groundwater, a valuable
source of cold water essential to creating refugia for many fish species.
Nationwide, farming and ranching operations represent large inputs of nitrogen and phosphorus.
The Freshwater Trust is working to measure the benefit of conservation actions that limit these
inputs while maintaining productive agricultural lands.

The Nutrient Tracking Tool (NTT) is a sophisticated modeling tool that allows the user to create a
detailed scenario of on-field agricultural practices (see sidebar for model inputs). NTT models the
agricultural practices and then estimates the annual nutrient and sediment loads that occur as a
result of these actions. NTT can model a wide assortment of conservation actions from riparian
—
restoration actions to changed practices on farms.

The retention parameter (s)
is variable and is dependent
on a number of site-specific

NTT calculates uplift in terms of nitrogen, phosphorus and
sediment load reductions by comparing baseline conditions of
a field to modeled conditions after restoration. The difference
represents the uplift from conservation actions.
The Nutrient Tracking Tool was designed and developed by
the United States Department of Agriculture (USDA) Natural

Case Study: Rudio Creek
Uplift from 2012 Project
n ecologically significant tributary of the North Fork John Day River, Rudio Creek provides
important habitat for federally-listed summer steelhead and spring Chinook. During the
early and mid-1900s, a portion of Rudio Creek that runs through a ranch was straightened
and channelized, draining wet meadow floodplain habitat to create livestock pasture. This
channelization, coupled with agricultural development of the floodplain throughout the mid-1900s,
led to the loss of riparian vegetation and beaver dam complexes. This resulted in a faster flowing
stream system with reduced habitat diversity and reduced cold-water storage capabilities.
Sean O’Connor, Freesolo Collective
Collecting thorough
baseline data allows scientists
to more precisely design a
restoration project.
The Freshwater Trust has restored Rudio Creek to mimic historic conditions to the greatest extent
possible. The illustration below details how habitat restoration actions were implemented on a
section of the Rudio Creek project.
1 Reconstruct historic channel: Reactivation of flow to the historic
channel provides habitat diversity and floodplain connectivity
and reverses the effects of straightening and channelizing the stream.
Restoring the stream to near-historic conditions increases its length
and offers greater potential habitat complexity. Creating bends and
wood structures allows for varying water velocities and for different
sizes of gravel and cobble — important for native fish — to be naturally
sorted and deposited.
2 Increase floodplain connectivity: Reconnecting the stream to its
floodplain allows water to spill over and facilitate the growth and
diversity of streamside vegetation. A connected floodplain also reduces
the stream’s speed during a flood event, preventing banks from eroding and creating opportunities
for secondary side channels to form.

4 Construct large wood structures: In undisturbed systems, dead wood naturally accumulates
in rivers and streams, adding to habitat complexity. During high flow periods, water carves
around and beneath these pieces of wood, creating deep pools where water stays cool. Structures
are constructed where they would be expected to occur under natural conditions and are designed
to be self-sustaining.
5 Restore native riparian vegetation: Native vegetation is planted along the banks of the creek,
providing channel stability, shade for the river, food for insects and fish, and materials for beavers,
birds and other animals to build shelter. While beavers are present in the system, their numbers and
influence on the river and floodplain have been greatly reduced. It is anticipated that this project and
its restored habitat conditions will support a larger beaver population and perennial dam complexes.
To restore Rudio Creek holistically, The Freshwater Trust also worked with private landowners
upstream and downstream of its on-the-ground project site to address instream flow issues.
An upstream water leasing agreement and a change to a downstream point of diversion restored
2.0 cubic feet per second (1.3 million gallons per day) of streamflow to Rudio Creek, increasing water
quality, lowering temperature in Rudio Creek and contributing cold water to the North Fork John Day.
3 Increase pool/pool-glide habitat: Pools provide slow water habitat,
spawning sized gravels and shelter for both adults and juvenile fish.

NOTES
* Soil data are not available for the project area in Grant County, therefore, a nearby proxy was used to calculate the uplift, making them rough estimates,
not exact numbers. The uplift is a result of the removal of grazing livestock from a single field in the project area. The modeled area is 2.3 acres.
** These numbers are from the Phase 1 planting of Rogue River. Additional planting will occur in the spring which will change the estimated uplift. The
uplift is a result of planting riparian vegetation. The modeled area is 1.3 acres.
