Present program period (2017-2022)
The research in Triekol III is structured in nine subprojects (see below), each derived from a particular question of importance to preserve and enhance biodiversity when constructing and managing roads and railways in Sweden. Despite linkages between subprojects, they are intended to function as work packages, i.e. each producing scientific publication and recommendations that can be implemented in Swedish Transport Agency´s (STA) steering documents and guidelines, and each with its given budget. Subprojects will as far as possible make use of data available from previous and ongoing monitoring projects, and relate these to the international knowledge level. Some minor subprojects are focused on completing previous studies, where smaller additional research is expected to provide important knowledge.
The project is divided in two major parts: Animals, dealing with the impacts on vertebrate population such as wildlife accidents, barrier to movement and noise disturbance, and Infrastructure habitats, dealing with the biodiversity directly related to the vegetation, such as plants, insects and other invertebrates, and pollen/nectar resources.
Triekol III includes the following subprojects:
- Wildlife adaptation of existing bridges
- Level crossings and wildlife warning systems
- Over- and underpasses for larger wildlife
- Modeling of permeability and mortality effects on wildlife populations
- Effect of noise measures for birds
- Amphibian passages
- Management and construction of road infrastructure habitats for biodiversity
- Management and construction of rail infrastructure habitats for biodiversity
- Ecological functions of infrastructure habitats
