How to use these flashcards

Work through these flashcards in short sessions. Try to answer each prompt before flipping the card, then revisit any cards you miss until the explanation feels automatic.

Flashcard 1: What is meant by sustainability in conservation solutions?

Answer: Meeting needs now without harming future resources. Sustainable solutions balance present and future needs.

Flashcard 2: What is an unintended consequence in an environmental solution?

Answer: An unexpected negative or positive side effect. Solutions can produce results beyond their intended goals.

Flashcard 3: Which criterion is most directly addressed by peer-reviewed data showing biodiversity increases?

Answer: Scientific criterion. Peer-reviewed data provides scientific evidence of effectiveness.

Flashcard 4: Which option best fits the scientific criterion: “lowest cost” or “largest pollution reduction”?

Answer: Largest pollution reduction. Pollution reduction is a measurable environmental outcome.

Flashcard 5: Which option best fits the social criterion: “accepted by residents” or “high species richness”?

Answer: Accepted by residents. Community acceptance is essential for social success.

Flashcard 6: Identify the best social choice: Plan A displaces families; Plan B avoids displacement (same results).

Answer: Plan B. Avoiding displacement better serves community well-being.

Flashcard 7: Which social measure best indicates community support: public survey approval or soil pH?

Answer: Public survey approval. Surveys measure community acceptance, pH measures chemistry.

Flashcard 8: Which option best reduces scientific uncertainty: a single test or multiple trials with controls?

Answer: Multiple trials with controls. Controlled experiments provide stronger scientific evidence.

Flashcard 9: Which criterion is being used if you ask, "Will this solution still work if rainfall decreases next decade"?

Answer: Scientific reliability under changing conditions (resilience). Tests if solution adapts to environmental changes.

Flashcard 10: Which criterion is being used if you ask, "Who pays, and who benefits, from this conservation rule"?

Answer: Social equity (fair distribution of costs and benefits). Examines if burdens and benefits are distributed fairly.

Flashcard 11: What is one scientific metric commonly used to evaluate a conservation solution?

Answer: Change in biodiversity (species richness or abundance). Biodiversity changes provide measurable ecological health indicators.

Flashcard 12: What is the scientific meaning of biodiversity in an ecosystem?

Answer: Variety of species and their relative abundance in an area. Biodiversity includes both number of species and population balance.

Flashcard 13: Which option best describes a trade-off in evaluating solutions?

Answer: A gain in one criterion causes a loss in another. Trade-offs require balancing competing priorities.

Flashcard 14: Which solution is more socially acceptable if $80\%$ support it vs $45\%$ support it?

Answer: The solution with $80\%$ support. Higher support percentage ensures better implementation success.

Flashcard 15: What social criterion focuses on who receives benefits and who bears burdens?

Answer: Equity (fair distribution of costs and benefits). Ensures no group bears unfair costs or misses benefits.

Flashcard 16: Which scientific evidence type most strongly supports a solution’s effectiveness: anecdotes or controlled data?

Answer: Controlled data. Controlled studies provide reliable, reproducible evidence.

Flashcard 17: Identify the scientific criterion in this statement: “Nitrate levels dropped from $10$ to $3$ mg/L.”

Answer: Measured reduction in nitrate concentration (water quality data). Quantitative measurements demonstrate scientific effectiveness.

Flashcard 18: What does the scientific criterion measure when evaluating a conservation solution?

Answer: Environmental effectiveness based on evidence and data. Scientific criteria rely on measurable outcomes and research findings.

Flashcard 19: Which solution is scientifically stronger: one tested in multiple sites or one tested once in one site?

Answer: Tested in multiple sites. Multiple sites provide broader evidence of effectiveness.

Flashcard 20: Which option is an example of an unintended consequence of a conservation solution?

Answer: A new problem caused by the solution, such as harming non-target species. Solutions can create unexpected negative effects.

Flashcard 21: What is the best scientific reason to prefer native plant restoration over introducing a non-native plant?

Answer: Lower risk of invasive spread and ecosystem disruption. Native species naturally fit local ecosystems without disruption.

Flashcard 22: Which solution is more economically feasible if budgets are limited: low upfront cost or high upfront cost?

Answer: Low upfront cost. Limited budgets require affordable initial investments.

Flashcard 23: What is the formula for percent change used to compare outcomes of two solutions?

Answer: $\frac{\text{new}-\text{old}}{\text{old}}\times 100\%$. Calculates relative change between two values.

Flashcard 24: What does an economic criterion measure when evaluating a conservation solution?

Answer: Costs, benefits, and financial feasibility over time. Economic criteria assess monetary aspects and long-term viability.

Flashcard 25: What does a scientific criterion measure when evaluating a conservation solution?

Answer: Ecological effectiveness based on evidence and data. Scientific criteria rely on measurable outcomes and research.

Flashcard 26: Which option best reflects sustainability: a one-time fix that fails in $1$ year or a plan lasting $20$ years?

Answer: A plan lasting $20$ years. Sustainable solutions maintain effectiveness over decades.

Flashcard 27: Which option best reflects equity: benefits go only to tourists or benefits include local residents?

Answer: Benefits include local residents. Equity means locals share in conservation benefits.

Flashcard 28: Identify the criterion: A solution restores wetlands but requires removing an invasive species first.

Answer: Scientific criterion (ecological interactions). Species removal and habitat restoration are ecological factors.

Flashcard 29: Identify the criterion: A solution reduces pollution but increases asthma in a nearby community.

Answer: Social criterion (human health impact). Health effects on people make this a social issue.

Flashcard 30: Which has the lower cost per hectare if both protect $10$ hectares: \5{,}000$or$$8{,}000$?

Answer: \5{,}000$solution.$$500$per hectare beats$$800$ per hectare.
