Project Description

Description
The possibility of restoring a run of steelhead trout to Alameda Creek has been the topic of sporadic discussion and study for over 50 years, and historical fish ladders in the watershed attest to concern for these fish even in the 19th and early 20th centuries. The Alameda Creek Fisheries Restoration Workgroup was formed in 1999 as a collaborative effort to pursue steelhead restoration. The Workgroup published a peer-reviewed assessment in 2000 that concluded suitable habitat exists in the watershed to support steelhead spawning and rearing. Since then, several barriers in the watershed have been removed, some fish passage facilities have been built and others are being planned, genetic testing of fish has been conducted, and screens installed on major water diversions. To formalize the activities of the Workgroup, and to design and conduct hydrologic studies to estimate the range, magnitude, timing, duration, frequency and location of flows necessary to restore steelhead fisheries (while minimizing the impacts to water supply operations), a Memorandum of Understanding was executed among multiple public agencies. The MOU envisions three phases for the hydrologic studies. Under Phase 1 (November 2006-January 2008), all the relevant existing data, reports, and studies on hydrologic and geomorphic conditions and fish habitat were reviewed to prepare a plan describing the studies necessary to achieve MOU objectives. In Phase 2 these studies are to be implemented to provide the information necessary to estimate the flows for restoration. Results from this second phase will form the foundation from which specific flow proposals that would support steelhead would be considered in Phase 3.

How to Use the Habitat Development Curve

Habitat Development Curves (HDCs) are used to determine the developmental status and trajectory of on-the-ground projects to create, restore, or enhance California wetland and stream habitats. Each HDC is based on assessments of habitat condition for different age areas of one habitat type that in aggregate represent the full spectrum of habitat development. The assessments of condition are provided by expert applications of the California Rapid Assessment Method (CRAM). Visit the CRAM website for more information about CRAM.

For each HDC, reference condition is represented by areas of a habitat that consistently get very high CRAM scores, have not been subject to disruptive management practices, and exist within landscapes that are protected and managed for their natural conditions. The horizontal lines intersecting the top of an HDC represent the mean CRAM score and standard deviation of scores for 25 qualifying reference areas.

The age of a project is estimated as the elapsed time in years between the groundwork end date for the project and the date of the CRAM assessment. To add or update a groundwork end date, use the Project Events form in Project Tracker (ptrack.ecoatlas.org). The minimum age in years of a non-project area, including any natural reference area, is estimated from all available local information, including historical maps and imagery, historical written accounts, and place-specific scientific studies of habitat development.

An HDC can be used to address the following questions:

  1. At what time in the future will the area of assessed habitat achieve the reference condition or other milestones in habitat development? The HDC can answer this question if the CRAM score for the assessed area is within the confidence interval of the HDC. The answer is the time in years along the HDC between the current age of the assessed area and the future date corresponding to the intersection of the HDC and the reference condition or other milestone.
  2. Is the area of assessed habitat likely to develop faster, slower, or at the same pace as most other areas of the same habitat type? The habitat area is likely to develop faster, slower, or at the same pace if the CRAM score for the area is above, below, or within the confidence interval of the HDC, respectively.
  3. What can be done to improve the condition of the habitat area or to increase its rate of development? HDCs by themselves cannot answer this question. Possible answers can be inferred by the following analysis that involves HDCs:
    1. Examine the HDC for each of the four CRAM Attributes;
    2. Identify the Attribute(s) scoring below the HDC;
    3. For any low-scoring Attribute, examine the component Metric Scores (note: the Metric Scores for any public CRAM assessment in the CRAM database can be obtained through EcoAtlas);
    4. Assume the low score of an Attribute is due to its low-scoring Metric(s);
    5. Consider modifying the design or management of the habitat area in ways that will sustainably increase its score(s) for the low-scoring Metric(s).

For more information about CRAM Attributes and Metrics, including their scientific rationale, see the CRAM Manual.
