Research & Best Practice

Enhancing green spaces in London where all natural pollinators can thrive, and their habitats can be enjoyed by all.

Research & Best Practice

Overview

Effective pollinator conservation depends on evidence-based decisions. Research helps identify which habitats, plants and management practices genuinely benefit pollinators, ensuring that conservation efforts deliver measurable results.

Why Research Matters

Prevents ineffective or harmful interventions
Guides planting and land-management choices
Identifies species most at risk
Helps measure environmental impact
Supports policy and planning decisions

Key Evidence-Based Principles

Diversity is more beneficial than density — a range of plant species supports more pollinator species than a large planting of just one or two types
Native plants typically support the broadest range of species; some non-native plants can also provide value, particularly where native flora is limited
Connectivity between habitats improves survival rates and allows recolonisation
Reduced pesticide use increases pollinator populations over time
Seasonal continuity of flowers — from early spring through late autumn — is essential

Sources of Pollinator Research

Universities and academic institutions
Conservation organisations such as the Bumblebee Conservation Trust and Buglife
Government biodiversity and nature recovery bodies
Ecological surveys and habitat assessments
Long-term monitoring programmes

Best Practice Recommendations

Prioritise habitat creation over hive installation
Plant for year-round forage, with particular attention to early spring and late autumn gaps
Maintain natural areas within urban landscapes
Monitor sites annually and adjust management in response
Share data with conservation networks to contribute to the wider evidence base
