The Biological Perspective, Why?

  • Often overlooked by engineers and planners, only to have negative

consequences realized when too late

  • Ensure that alterations are necessary, and have as little negative ecological

impact as possible

  • Ensure no harm to endangered species
  • Environmental, quality of life, and economic impacts
  • Economic: Commercial harvest, recreational use, tourism, create restoration

needs, control invasive species

  • Avoid mistakes of the past with unintended consequences

Unintended Consequences

  • Lowers water quality
  • Lower fisheries production
  • Replaces important

substrates

  • Impedes navigation and

boat access

  • What: Standardized Fisheries Data
  • Where:
  • LDWF Fisheries Database
  • DEQ Database
  • Data Quality: High. Georeferenced and

usually tied to water quality data.

  • Going back decades
  • Often standardized, replicated
  • Game fish, some nongame datasets
  • Data Gaps:
  • Gear types
  • Focus of sampling (i.e.

sport/commercial species, not full assemblage)

  • Historic standardization
  • Freshwater invertebrates.

Data Needs

  • Increased mussel surveys
  • Digitize historical collections
  • Share “pet” datasets
  • Increased standardized efforts, undersampled areas,

and species

  • Flow-ecology hypotheses/life history studies
  • Population/community trends and land use
  • Ecological Limits of Habitat Alteration (ELOHA)
  • Economic benefits of natural areas

Conclusion

  • Many datasets available to inform models, decision making
  • Much work to be done to find other datasets, fill in gaps, standardize
  • Societal benefits must be weighed against biological consequences
  • ++, +-, -+, --
  • Do not want to repeat mistakes of past we’re dealing with today
