Control in Road

Project aims

Compile a list of IAPs related to roads for selected European countries
Evaluate new methods of IAPs management
Develop a best practice guide for road construction and maintenance
Apply cost-benefit analysis for best practices

About the Project

In this project, engineers and researchers, with expertise from different disciplines, formed a consortium aimed at developing and evaluating methods to prevent the spread of invasive alien plant species (IAPs) during road construction and maintenance.

IAPs are a threat to biodiversity, economy and health. Habitats related to roads play an important role in facilitating the establishment of IAPs by providing a suitable habitat as well as serving as corridors for their dispersal.

Icon for questionnaire

This survey addresses national and international experts with knowledge about the problem of invasive alien plant species, as well as other interested individuals.

The survey aims to:

  1. Create awareness on the problem of IAPs during road construction and maintenance
  2. Assess current knowledge on:
    1. Invasive alien plant species
    2. Existing laws, standards, and routines
  3. Assess:
    1. Problems caused by IAPs on roads
    2. Existing measures to control IAPs in road construction and road maintenance
