Utrecht University announced on 4 November 2026 that it had completed 2.5 hectares of new nature at Utrecht Science Park, where education, healthcare, housing and research compete for space. The university also launched a six-kilometre biodiversity walk.

The completed area is about seven football pitches and forms the first ecological corridor, a 1.6-kilometre north-south strip between the Oostbroek estate and Fort bij Rhijnauwen. The university says the corridor is intended to connect the campus with surrounding nature areas, strengthen biodiversity and make the area more attractive to plants and animals. Its announcement describes the area as completed but does not state that it has opened as a public nature reserve.

Part of a larger corridor plan

The north-south corridor is the first of two wide green strips planned by the university. Together, the two corridors are expected to cover about 10 hectares. The second, east-west connection is planned south of Toulouselaan and Limalaan towards the A27.

The corridor programme uses ponds, trees and shrubs, flower-rich grassland and nature-friendly ditch banks. Nutrient-rich topsoil is removed in some places to give more plant species a chance to establish. The university names the great crested newt, the whitethroat and the spotted orchid among its target "icon species". Its wider biodiversity plan aims for 20 icon species to be permanently established at the Science Park by 2035, an outcome that has not yet been demonstrated.

The southern part of the north-south corridor was formally opened on 28 October 2025. The university's construction schedule says preparatory work followed later that year and the northern part was built from August to late October 2026. Utrecht University, the municipality, the province and Staatsbosbeheer were among the partners involved in the wider corridor and wildlife-passage programme.

The university also plans an east-west corridor. A 2025 project update said construction would start in 2026, while the university's current corridor page says work will take place across 2026 and 2027 and that the exact schedule is still being developed. The De Stichtse Rijnlanden water board made €80,000 available through an incentive scheme for that second link.

Animals also need to cross roads to move between habitats. In August 2025 the university reported two wildlife tunnels under the Rijnsoever and Zandlaan, intended for animals including hedgehogs, toads and badgers. A separate passage near Oostbroek was built by the municipality of De Bilt in autumn 2024.

A six-kilometre walk to learn the species

Alongside the corridor's completion, the university launched a "Biodiversity USP" walk in the Utrecht Time Machine app. The six-kilometre route stops at locations around the Science Park and introduces the university's history and 20 guide species that either live there now or are hoped to arrive. It is available as an audio tour or as text with photographs and was developed for the university's 390th anniversary.

Nature areas take years to mature. Utrecht University says the new habitat is intended to help species settle, but the November announcement does not report ecological monitoring results or say how many of the 20 target species are already established.

For residents, the immediate changes are the completed north-south green strip and a guided route explaining the plants and animals the university hopes it will support.
