Stakeholder sampling in environmental preference studies
Environmental policies often affect specific stakeholder groups - farmers, fishers, land managers, local communities - whose preferences may differ substantially from the general public.
This article explains how to define and recruit stakeholder groups for environmental preference studies, and how to compare stakeholder and general public preferences in your analysis.

Why stakeholder samples matter in environmental research
Environmental policies create winners and losers. A biodiversity offset programme may require farmers to set aside land, reducing their income. A river restoration programme may affect fishing rights. A coastal management scheme may change beach access for local communities. The preferences of these directly affected stakeholders may differ substantially from the general public - and policy analysis may need to account for these differences separately.
Standard general population samples do not include sufficient numbers of specific stakeholder groups for separate analysis. If you need to estimate stakeholder WTP separately from general public WTP, you need a targeted stakeholder sample.
Defining and recruiting environmental stakeholders
Relevant stakeholder groups vary by policy context. For agricultural environment schemes: farmers and land managers. For marine conservation: fishers, coastal tourism operators, and recreational water users. For urban green space: residents within the catchment, regular park users, and people with mobility or health conditions that affect their use of outdoor spaces.
Stakeholder recruitment is typically more challenging than general population recruitment. Farmers and land managers are not well-represented in online panels; they are better reached through farming industry networks, National Farmers Union membership, or direct mail to agricultural businesses. Fishers and marine stakeholders may be accessible through fishing club memberships or harbour authorities.
SurveyEngine's respondent sourcing service has experience recruiting specialist environmental stakeholder groups for government-commissioned studies and has established relationships with relevant industry and community organisations.
Setting up stakeholder sampling with SurveyEngine
Step 1: Define your stakeholder groups precisely. For each group, write a precise eligibility definition: land manager with at least 50 hectares within the catchment; active fisher with at least 20 fishing days per year in the affected area; park user who visits at least once per week.
Step 2: Choose the appropriate recruitment channel for each group. Farmer samples through NFU or equivalent; fishing samples through angling clubs; community samples through local authority community panels or on-site recruitment at the relevant location.
Step 3: Design separate screeners for each stakeholder group. Each group needs questions that confirm their eligibility status. Farm size, fishing frequency, and park visit frequency are stronger eligibility indicators than self-reported stakeholder identity.
Step 4: Plan the analysis to compare stakeholder and general public preferences. Use interaction terms or latent class models to test whether preferences differ significantly between stakeholder groups. Report stakeholder WTP separately from general public WTP.
Step 5: Consider participatory research approaches. For highly affected stakeholder groups, co-design of the research - involving stakeholders in defining the attributes, levels, and scenarios - may improve the validity and acceptability of the results.
Worked example - upland moorland management study
A study of public preferences for upland moorland management includes three samples: general public (n=500, online panel), upland farmers (n=100, NFU member mailing), and birdwatching and conservation society members (n=100, RSPB and BTO member email recruitment).
WTP for increased biodiversity indicators on moorland is £34/year (general public), £12/year (farmers - lower, possibly due to opportunity cost awareness), and £89/year (conservation society members - higher, reflecting stronger environmental preferences). The policy report presents all three estimates and their implications for the cost-benefit analysis.
