**

The Tualatin 8-Digit Hydrologic Unit Code (HUC) subbasin is comprised of
453,300 acres, most of which is in Washington County. Forty-nine percent
of the subbasin is forestland. Twenty-three percent is under hay and
pasture, which includes dairy and beef operations and most of the small
farms. Other areas are used for small grain, grass seed, orchards,
vineyards, nursery stock, caneberries, blueberries, strawberries,
cannery crops, and nuts. Resource concerns associated with these land
uses include streambank erosion, surface water contamination,
undesirable odors from CAFOs, and increasing land use restrictions.
There are 27 permitted CAFOs in the subbasin.

There are 2,163 farms in the subbasin and 3,473 operators. Three-fourths
of the operations are relatively small, commonly less than 50 acres. The
greatest obstacle to the diffusion of conservation among small acreage
landowners is that they have little experience implementing conservation
and managing natural resources

One NRCS service center, the Tualatin Soil and Water Conservation
District, the Northwest Resource Conservation & Development (RC&D)
office, and other local conservation organizations provide conservation
assistance in the Tualatin subbasin.

-   Sheet and rill erosion by water on the croplands and pasturelands
    have been reduced more than 36,000 tons of soil per year from 1982
    to 1997.

```{=html}
<!-- -->
```
-   NRI estimates indicate that 11,400 acres of the agricultural lands
    still had water erosion rates above a sustainable level in 1997.

```{=html}
<!-- -->
```
-   Controlling erosion not only sustains the long-term productivity of
    the land, but it also affects the amount of soil, pesticides,
    fertilizer, and other substances that move into the Nation's waters.

-   More than 80 percent of the listed stream miles exceed State water
    quality standards for temperature. Elevated stream temperatures may
    be due to inadequate riparian shade, stream channel widening, and
    other anthropogenic or natural causes.

-   Fecal coliform and E coli can be indications of livestock waste
    runoff, but they also are typical of poorly functioning onsite
    sewage disposal systems and urban runoff.

-   Phosphorus may be related to agriculture or residential use, and the
    area is known to have high background levels.

-   Conservation practices that can be used to address these water
    quality issues include grazing management, nutrient and pest
    management, and use of riparian buffers.

  ----------------- --------------------------------- ------------------ --------- --------- ------------------ ----------------- ------------

**Pasture/Hay**

-   Forage and grazing management on pastureland on small farms and
    ranches sometimes is inadequate, resulting in resource concerns of
    streambank erosion and water quality.

-   Proper waste management is needed for livestock operations to
    maintain water quality and avoid soil contamination associated with
    nutrients and pathogens, especially around the livestock
    headquarters.

-   Odor is commonly a problem around CAFO headquarters or fields where
    manure is being applied.

**Grass Seed\\Grain**

-   Grass seed is commonly produced under contract and in rotation with
    grain. Erosion is the primary concern, especially during the years
    when the grass seed is becoming established.

-   Smoke from burning stubble after harvesting sometimes creates issues
    for health and safety.

**Row & Perennial Crops**

-   Management of residue, nutrients, and pests and use of filter strips
    and buffers are needed to control erosion and maintain water
    quality. Irrigation water management is an issue for irrigated
    crops.

-   Filberts and Christmas trees can be difficult to manage to avoid
    erosion.

**Forest**

-   Non-industrial forestland owners commonly are concerned with
    aesthetic value, not timber production.

-   Concentrated flow erosion from roads and landings and overstocking
    are the main issues in areas of private forestland that is used for
    timber production.

**General**

-   Land use constraints and pressure to develop hinder investment in
    conservation. Viable production agriculture in the watershed is
    diminishing.

-   Increasing land values and conflicting urban-rural land use raise
    serious social, political, and economic concerns for resource
    management in the watershed.

**Number of Farms: 2,163**

**Number of Operators: 3,473**

-   Full-Time Operators: **648**

-   Part-Time Operators: **2,825**

**Estimated Level of Willingness and Ability to Participate in
Conservation**[^[/15]{.underline}^](#Footnote15)**: Moderate**

Overall, landowners in the Tualatin subbasin tend to be amenable to
conservation and natural resource management. As a group, they exhibit a
positive stewardship attitude, are well educated, and have a fair
understanding of the local resource concerns.

The greatest obstacle to the diffusion of conservation among small
acreage (less than 50 acres) landowners is that they have little
experience implementing conservation and managing natural resources.
Additional technical and financial assistance may be necessary to
encourage these landowners to adopt conservation systems on their land.

**Evaluation of Social Capital**[^[/16]{.underline}^](#Footnote16)**:
Low to Moderate**

Social capital in the Tualatin subbasin and the ability of the
communities to successfully address local resource concerns appears to
be low to moderate. The greatest strengths of the communities are that
they are well connected via the internet, residents are well educated,
and community projects, once started, are usually completed. Communities
in the subbasin may benefit by encouraging more participation in
resource-based organizations, improving leadership effectiveness, and
getting more widespread participation in community decisions from all
residents, including minorities.

-   []{#progressstatus .anchor}Progress over the last 5 years has been
    focused on:

```{=html}
<!-- -->
```
-   Nutrient, pest, and irrigation water management on CAFOs and
    cropland.

-   Erosion control on cropland.

```{=html}
<!-- -->

```
-   Farmers producing row crops, such as corn, beans, and cole crops,
    commonly rely on cannery consultants and fertilizer dealers.

-   Farmers producing perennial crops, such as nursery stock and
    Christmas trees, commonly do not seek assistance from NRCS or SWCDs.

-   Much of the pasture that is at the benchmark level is on small
    farms.

-   Private industrial forestland owners typically do not work with NRCS
    and SWCDs; however, their land commonly complies with State forest
    practice requirements.

-   Much of private non-industrial forestland is on farms of less than
    50 acres in size that are not managed for timber production.
    Frequently, this land does not comply with the State forest practice
    requirements.

*Estimates are based on information received from local conservationists
in the watershed.*

1.  Ownership Layer -- Source: The 1:24,000 scale public ownership layer
    is the land ownership/management for public entities, including
    Federal, Tribal, State, and local entities. This is a seamless,
    statewide Oregon Public Ownership vector layer composed of fee
    ownership of lands by Federal, State, Tribal, county, and city
    agencies. The layer is comprised of the best available data compiled
    at 1:24,000 scale or larger, and the line work matches GCDB boundary
    locations and ORMAP standards where possible. The layer is available
    from the State of Oregon GIS Service Center:
    <http://www.gis.state.or.us/data/alphalist.html>. For current
    ownership status, consult official records at appropriate Federal,
    State, and county offices. Ownership classes grouped to calculate
    Federal ownership vs. non-Federal ownership by the Water Resources
    Planning Team.[]{#Footnote2 .anchor}

    Abstract: These data can be used in a geographic information system
    (GIS) for any number of purposes, such as assessing wildlife
    habitat, water quality, pesticide runoff, land use change, etc. The
    State data sets are provided with a 300-meter buffer beyond the
    State border to facilitate combining the State files into larger
    regions.[]{#Footnote3nri .anchor}

3.  ESTIMATES FROM THE 1997 NRI DATABASE (REVISED DECEMBER 2000) REPLACE
    ALL PREVIOUS REPORTS AND ESTIMATES. Comparisons made using data
    published for the 1982, 1987, or 1992 NRI may produce erroneous
    results. This is because of changes in statistical estimation
    protocols and because all data collected prior to 1997 were
    simultaneously reviewed (edited) as 1997 NRI data were collected.
    All definitions are available in the glossary. In addition, this
    December 2000 revision of the 1997 NRI data updates information
    released in December 1999 and corrects a computer error discovered
    in March 2000. For more information:

15. []{#Footnote15 .anchor}Conservation participation was estimated
    using NRCS Social Sciences Technical Note 1801, [Guide for
    Estimating Participation in Conservation]{.underline}, 2004. Four
    categories of indicators were evaluated: Personal characteristics,
    farm structural characteristics, perceptions of conservation, and
    community context. Estimates are based on information received from
    local conservationists in the watershed.

16. []{#Footnote16 .anchor}Social capital is an indicator of the
    community's ability and willingness to work together to solve
    problems. A high amount of social capital helps a community to be
    physically healthy, socially progressive, and economically vigorous.
    A low amount of social capital typically results in community
    conflict, lack of trust and respect, and unsuccessful attempts to
    solve problems. The evaluation is based on NRCS Technical Report
    Release 4.1, March, 2002: [Adding Up Social Capital: An Investment
    in Communities]{.underline}. Local conservationists provided
    information to measure social capital. Scores range from 0 to 76.
