Title: Endangered Species Act
1Endangered Species Act
- Standards of Review for Determining Effects
2Overview of Standards
- Provide the Logical Basis for the Analysis
- Reflect Services Process for Evaluating and
Concurring with Action Agency NLAA Determinations - Foundation is in an Analysis of Exposure and
Response
3Overview of Process
4Identify and Deconstruct the Action
- Where is the geographic location?
- What is the purpose of the action?
- When is the action planned for implementation?
- How long will it take?
- What are the interrelated and interdependent
activities (if any)? - Are there any applicants?
5Identify and Deconstruct the Action
Diversion
Channel across the slope
Vegetative cover
6Identify and Deconstruct the Action
Streambank Stabilization
Grading and Shaping
Planting/ Armoring
7Identify the Action Area
- Direct Effects
- Indirect Effects
- Action Area
8Identify the Action Area
- Direct Effects are those that are immediate.
- Indirect Effects are those caused by or result
from the proposed action, are later in time, and
are reasonably certain to occur.
9Identify Species and Critical Habitat
- Maintain current species lists
- Species and critical habitat that overlap with
the action area - Frames future analysis for effects determination
10Species Biology(provides context for how species
may be affected)
- Range
- Seasonal Distribution
- Population Stability
- Population Dynamics
- Life History
- Life Stages
- Threats to the species
11Effects of the Action
- Exposure Analysis Will a species or Critical
Habitat be exposed to environmental effects
(direct and indirect) of the action? - Response Analysis If exposed, what is the
species or Critical Habitat response? - (insignificant or discountable or completely
beneficial or adverse?)
12Exposure Analysis
- Establishes the connection between a probable
environmental effect (impact) and the species or
critical habitat - Is there exposure?
- What is the exposure?
- Where would it occur?
- Does exposure vary over time?
13Exposure AnalysisFactors to Consider
- Probability
- (will an environmental effect actually occur?)
- Proximity
- (where is the effect in relation to the listed
resource?) - Magnitude
- (what is the severity and intensity of the
effect?) - Distribution
- (what is the geographic area in which the effect
will occur?) - Frequency
- (how often will it occur?)
- Duration
- (how long will it last?)
- Timing
- (when will it occur?)
14Response Analysis
- Combines information in exposure analysis with
information on the biology of the species or
condition of Critical Habitat - Exposure must elicit a response or reaction from
the species or Critical Habitat
15Response Analysis
- Action results in noise
- Noise disrupts breeding cycle
- Noise does not disrupt foraging
- Action implemented after breeding season
- Action does not illicit a response from the
species
16Response Analysis
- Responses can be
- Insignificant
- Discountable
- Completely beneficial, or
- Adverse
- Disruption of essential behavioral patterns
result in negative and adverse responses
(incidental take), regardless of long-term net
benefits
17Response AnalysisOther Considerations
- Effect of the action condition post-
implementation compared to pre-implementation - Species resiliency
- Uncertainty
- Use of best available information?
- Action modification to decrease risk?
- Incorporation of new information?
18Example (Bull Trout) A riparian restoration
project is proposed along the Snohomish River.
- The project causes exposure because
- Bull Trout use the Snohomish River within the
action area. - The proposed project will increase the potential
for sediment to be released into the River within
the action area.
19Example (Bull Trout) A riparian restoration
project is proposed along the Snohomish River.
- The response is insignificant and discountable
because - The project does not have in-water work
components. - The project is located above the ordinary high
water mark of the Snohomish River. - The project includes the planting of woody
vegetation along the approximately 10,000 square
feet of shoreline. - To avoid erosion and sedimentation, earthwork
will be limited to the summer and will be
completed by August 31. Disturbed ground will be
mulched and seeded.
20Example (Bald Eagle) A riparian restoration
project is proposed along the Snohomish River..
- The project causes exposure to the bald eagle and
bald eagle habitat because - Noise impacts from equipment and human activity
will occur adjacent to the Snohomish River where
wintering and foraging bald eagles might occur. - Suitable perching and foraging habitat occurs
within the action area.
21Example (Bald Eagle) A riparian restoration
project is proposed along the Snohomish River.
- The response is insignificant and discountable
because - Noise impacts from equipment and human activity
will be limited to the time period between August
15 and December 15 to avoid nesting and wintering
activities. - The project will not result in impacts to bald
eagle prey species. - No significant loss of suitable perching or
foraging habitat will occur. - The nearest nesting territory is approximately
0.5 miles away and is not in line of sight.
22Determination of Effect
- A summary of the facts that led to the conclusion
- If ALL responses are insignificant, discountable,
or completely beneficial determination is NLAA - If ANY response is adverse determination is LAA!
23NLAA
- Insignificant effects relate to the size of the
impact and should not be able to be meaningfully
measured, detected, or evaluated. - Discountable effects are those extremely unlikely
to occur - Beneficial effects are any positive effect
without adverse effects to the speciesincluding
short-term adverse effects.
24NLAA
- Ultimately, NLAA and other effects
determinations, are based on best judgment, after
complete analysis and consideration of all the
evidence.
