Community Science Partnership: eDNA evidence for local land management
Students team up with a land trust or park agency to survey species of local management concern and present findings to the public.
Working directly with a local land trust, park, or natural-resource agency, students identify five species of active management concern at a partner site, run a single composite eDNA sample, interpret the results as evidence for a real management question, and deliver a public-facing presentation to their community partner.

How one kit serves a whole class
The $200 Classroom Starter Kit holds one collection vial, targets up to five species, and returns results in 7–10 days into the class Field Journal. Because the class is answering a real question for a real partner, species selection is driven by the partner's stated management priorities rather than by student curiosity alone. A single composite batching protocol pools sub-samples from across the partner site into the one vial, and the results become the evidentiary backbone of a public report delivered back to the partner organization.

Research tracks
Track A — Species of Concern Monitoring
Rare, threatened, or declining species tracked by the partner agency
Driving question. Is a species the land trust already lists as declining or of concern still present at this site?
Species to pick. Up to five species drawn directly from the partner's own species-of-concern or watch list (e.g., a state-listed amphibian, a declining native fish, a sensitive mussel or crayfish, a rare native plant's associated pollinator, a bird species tied to the habitat type).
What students take away. Students hand the partner organization detection evidence they can fold directly into their own monitoring records.
Track B — Invasive Early Detection
Biosecurity and rapid response
Driving question. Has an invasive species the agency is watching for already arrived at this site, even if no one has seen it?
Species to pick. Two or three invasive species the partner is actively monitoring for (e.g., an invasive crayfish, mussel, or fish) paired with two or three native species that same invasive is known to displace, chosen in consultation with the partner.
What students take away. Students produce an early-warning report that could trigger a real rapid-response management action.
Track C — Restoration Success Check
Evaluating a completed or ongoing restoration project
Driving question. Is the community's restoration project (streambank planting, dam removal, wetland reconstruction) bringing target species back?
Species to pick. Five species the restoration project was explicitly designed to benefit, identified from the partner's restoration plan or grant documents (e.g., a fish species the project aimed to reconnect habitat for, a native plant's dependent insect, an amphibian expected to recolonize).
What students take away. Students provide the partner with outcome data that can support (or challenge) a grant report or public update.
The lesson sequence
Step by step, with teacher notes
- 01
Partner intake and problem framing
50 minutesA representative from the local land trust, park, or agency (in person or by video call) presents a real management question they need help answering. Students take notes, ask clarifying questions, and begin narrowing the field toward five target species that match the partner's actual priorities and the kit's limits.
Teacher notes
- Contact the partner organization at least two to three weeks ahead — most land trusts and parks departments are glad to send a biologist or ranger for a 20-minute video call.
- Say before the call: "We are not choosing species because they're interesting to us. We're choosing them because our partner needs this information."
- Have students draft three clarifying questions for the partner in advance so the call time is used efficiently.
- After the call, run a short group triage: cross off any partner-suggested species not detectable by eDNA or clearly outside the five-species, one-vial, $200 constraint.
Materials
- Video call setup or in-person partner visit
- Partner's species-of-concern list or restoration plan (requested in advance)
- Note-taking handout
- Site map from the partner
Student prompts
- What specific management decision is our partner trying to make, and how could our data inform it?
- Which of the partner's priority species can realistically be targeted with one composite sample?
- What would count as a 'useful' result to hand back to this partner, even if it's a non-detection?
- 02
Site visit and finalizing the five species
50 minutesStudents visit the partner site (or study its map and photos if an in-person visit isn't possible) to ground their species list in real habitat conditions, then finalize and defend the five targets as a class before ordering the kit.
Teacher notes
- If an in-person site visit isn't feasible, request recent photos, a site map, and habitat notes from the partner and run this as a virtual site study.
- Push students to connect each of the five species picks to a specific habitat feature they can see or read about at the site — 'why here, why this species' should be answerable for each one.
- Have the class vote on the final five, then have one student read the finalized list aloud to confirm consensus before it's locked in.
- Remind students that this list represents a commitment to the partner — treat it as a professional deliverable, not a rough draft.
Materials
- Partner site map and/or photos
- Field notebook
- Finalized species-selection worksheet
- Local field guide or regional species reference
Student prompts
- What habitat feature at this site supports or argues against each of our five species picks?
- How does this site's condition compare to what the partner described as their concern?
- What is our one-sentence justification for each species, ready to share with the partner?
- 03
Composite sample collection
50–60 minutesThe class runs a single composite batching protocol at the partner site: several crews draw sub-samples from distinct points across the site and pool them into the one vial, treating the sample as a shared deliverable on behalf of the whole class and the partner organization.
Teacher notes
- Say before anyone touches equipment: "Gloves on first. This sample represents our partner's site — if it's contaminated, we've wasted their trust as well as our kit."
- Walk the site in advance (or have the partner flag) three to five genuinely distinct sampling points that reflect the site's variation.
- Rotate roles — sampling, scribing, site-conditions logging, chain-of-custody — so every student has a defined job in producing the single sample.
- Model the pooling step yourself before letting students seal the final composite sample and prepare the return mailer.
- Invite the partner representative to attend the collection day if possible — it reinforces that this is real work for a real client.
Materials
- 1 classroom eDNA collection vial and prepaid mailer
- Nitrile gloves (one pair per student minimum)
- 3–5 sterile sub-sample cups or bags
- Site-conditions data sheet on clipboard
- Camera or phone for site-condition photos to include in the final report
Student prompts
- Sampling crew — draws sub-samples from three to five distinct points across the partner site.
- Site-conditions crew — records weather, water or soil conditions, visible disturbance, and any signs of the target species.
- Chain-of-custody crew — pools, preserves, seals and labels the composite sample and prepares the mailer.
- Documentation crew — photographs the site and collection process for the final public presentation.
- 04
Interpreting results for a real audience
50 minutes, once results arrive (7–10 days after mailing)Students receive the class Field Journal results and must translate raw detection data into a message a non-scientist partner audience can use, distinguishing between what the data shows and what it means for the partner's actual management question.
Teacher notes
- Say: "The land trust doesn't want a jargon dump — they want to know what to do next. Your job is to translate the science into a decision."
- Require each team to write one sentence a non-scientist board member could understand for each of the five species.
- Ask: "Which result would change what our partner does tomorrow, and which is just interesting?"
- Have students draft the CER analysis before building slides, so the presentation is built on a defensible claim rather than a data dump.
Materials
- Class Field Journal report (projected)
- CER writing frame
- Plain-language translation worksheet
- Presentation template or slide software
Student prompts
- Claim — what should our partner conclude about each target species at this site?
- Evidence — what specific relative-signal values and site conditions support that conclusion?
- Reasoning — how does this connect to the management question the partner originally asked?
- 05
Public presentation to the community partner
50 minutesStudents present their findings and a management recommendation to the partner organization (in person, by video call, or at a public event such as a school science night or town meeting), fielding questions from real stakeholders.
Teacher notes
- Invite the partner, and if possible other stakeholders (parents, local officials, a reporter from a school or local paper), to attend the presentation.
- Say beforehand: "You are the experts in this room on this specific dataset — own that, even if you're nervous."
- Require every presentation to end with a concrete recommendation, not just a summary of results.
- Debrief afterward: ask students what question from the partner or audience they weren't prepared for, and why.
Materials
- Finished slide deck or poster
- Printed one-page summary for the partner
- Q&A note-catcher
- Partner and audience feedback form
Student prompts
- What is our single most important finding, stated in one sentence?
- What management action does our evidence support?
- What would we recommend the partner monitor next, and why?
Student handout
For every student
Thinking prompts
- Summarize the management question our community partner asked us to help answer.
- List the five target species and, for each, the specific reason the partner or the site conditions justify it.
- Describe the composite batching procedure your crew followed at the partner site, in order.
- Explain what a detection or non-detection would mean for the partner's actual decision, before results arrive.
- After the reveal, state your team's core evidence-based claim in one sentence.
- Draft the plain-language version of your claim, written for someone with no science background.

Analysis
CER: What should our partner do with this evidence?
- 1.Claim — write one sentence stating what our results mean for the partner's original management question.
- 2.Evidence — list the specific relative detection values and site conditions that support the claim.
- 3.Reasoning — explain, using each species' habitat needs and the partner's management goals, why the evidence supports the claim.
- 4.Counter-evidence — identify one result that complicates the claim and address it honestly.
- 5.Recommendation — state one specific action the partner could take based on this evidence.

For the teacher
Answer key and misconceptions
- Expected: students should be able to state the partner's management question in one sentence without jargon before moving to species selection.
- Common misconception: a non-detection means the species is definitely gone. Correct framing: eDNA gives a probability of detection at the time and place of sampling, not certainty of absence — this must be communicated carefully to the partner.
- Common misconception: any interesting result is worth reporting to the partner. Correct framing: results should be filtered through the lens of 'does this inform the partner's actual decision.'
- Expected: the final recommendation should tie directly back to the original management question posed in Phase 1, not be a generic summary of the data.
- Common misconception: the class's job ends when the Field Journal results arrive. Correct framing: translating and delivering the results responsibly to a real-world audience is part of the scientific process, not an add-on.
