Prioritize Ecologically Diverse Native Plants for Habitat Restoration to Support Rare Pollinators

Restoration efforts using readily available, common plant species can lead to functional homogenization of pollinator communities, potentially harming rare and specialized pollinators.

Journal of Applied Ecology · 2025

Key Findings

01Readily available native plant genera frequently occur in plant-pollinator networks and are attractive to pollinators.
02A smaller number of readily available plant genera can support most common pollinator species.
03Readily available plants fulfill redundant functional roles, supporting overlapping assemblages of abundant pollinators.
04Simulated flower mixes of common native plants supported fewer rare and less-selective pollinators compared to random selections.

Application

Design takeaway

How to apply

When planning a green space, community garden, or any habitat restoration project, research the specific pollinator communities in the area and select a diverse range of native plants that are known to support both common and rare pollinators, rather than just those that are most readily available.

Project actions

01When designing a habitat restoration project, consider the functional roles of plant species in supporting diverse pollinator assemblages.
02Investigate the availability and ecological value of native plant species for your specific region.

Method & Evidence

AimTo evaluate whether commercially available native plant genera in temperate grasslands fulfill valuable functional roles for plant-pollinator interaction diversity and support rare and specialized pollinators.

MethodQuantitative analysis of plant-pollinator interaction data from existing studies.

ProcedureResearchers analyzed data from 673 plant-pollinator networks across 17 studies in European temperate grasslands. They assessed the frequency of occurrence, attractiveness to pollinators, and functional roles of readily available versus less-available native plant genera. Simulated flower mixes were used to compare pollinator community support.

Sample673 plant-pollinator networks within 17 different studies

ContextTemperate grassland ecosystems in Europe, focusing on habitat restoration for pollinator conservation.

Variables

IVType of native plant genera used in habitat mixes (readily available vs. limited availability).

DVPollinator species diversity, abundance, and functional roles supported by the plant mixes.

CVTemperate grassland ecosystem, European region, plant-pollinator interaction data from existing studies.

Strengths & Limitations

Strengths

+Utilizes a large dataset from multiple studies, increasing generalizability.
+Provides practical insights for ecological restoration practices.

Limitations

The availability of specific native plants can be a practical constraint in many regions. Local climate and soil conditions will also influence plant success.

Reliability & validity

The study's reliance on meta-analysis of existing data contributes to its reliability. Validity is supported by the quantitative analysis of interaction networks. However, the ecological context of each original study could introduce variability.

Think critically

How can designers balance the practical constraints of plant availability with the ecological imperative to support diverse pollinator communities in restoration projects?

Design Principles

"Ecological functional diversity in plant selection is crucial for comprehensive pollinator conservation in habitat restoration."

This research highlights a critical flaw in many habitat restoration projects that rely on easily sourced plants. While these plants attract common pollinators, they fail to support the full spectrum of pollinator diversity, including rare and specialized species. Designers and researchers involved in ecological restoration must consider the functional roles of plant species, not just their availability, to achieve truly effective biodiversity conservation.

What This Means for Your Design

If you're trying to help bees and butterflies by planting flowers, using only the most common and easy-to-find flowers might not be enough. It's better to choose a variety of native flowers that offer different things to different types of pollinators, especially the less common ones.

How to use in your project

1.Reference this study when discussing the importance of biodiversity and ecological function in your design project's justification or evaluation.
2.Use the findings to support your choice of materials or strategies that promote ecological diversity.

Paragraph starter

The research by Glenny et al. (2025) indicates that habitat restoration efforts relying on commercially available, common plant species can lead to the functional homogenization of pollinator communities, thereby failing to support rare and specialized pollinators. This underscores the importance of selecting native plant species based on their unique ecological roles within plant-pollinator networks to ensure comprehensive biodiversity conservation in design interventions.
