Zunzgen: adaptive restoration of Parcel 1988

The Zunzgen project is a flagship restoration case within NATURASCHUTZ.CH. Centered on Parcel 1988, a former extraction site, it brings together adaptive renaturation, biodiversity monitoring, drone mapping, ecological subdivision, and long-term field analysis.

Introduction

Parcel 1988 serves as a field-based proof of concept for adaptive restoration: a site where ecological recovery is approached through observation, flexibility, data, and the careful reading of ecological functions over time.

A degraded site approached as a living ecological system

Parcel 1988 in Zunzgen, covering approximately 14,810 m², has been heavily shaped by limestone extraction and the deposition of construction materials. Rather than treating the site as a uniform degraded area, the project reads it as a dynamic ecological system with distinct zones, functions, limits, and restoration potentials.

Former extraction site

The parcel bears the marks of quarry activity, topographical disruption, altered hydrology, and ecological fragmentation.

Adaptive restoration logic

Restoration is guided by continuous observation, ecological feedback, and the capacity to adjust management strategies when the site behaves differently than expected.

Biodiversity focus

The project aims to improve habitat quality, strengthen ecological functions, and support biodiversity through field-based analysis and management.

Long-term vision

Parcel 1988 is not treated as a short intervention, but as a long-term restoration territory requiring structured monitoring and evolving ecological understanding.

Main components of the restoration work

The project integrates several lines of ecological understanding and intervention, each contributing to a broader restoration logic.

Amphibian zones

Artificial pools and surrounding areas are assessed in terms of accessibility, predator pressure, hydrological suitability, and real ecological value for amphibian life.

Forest continuity

North, middle, and south forest sectors are studied as parts of a larger ecological network supporting wildlife movement and habitat connectivity.

Reptile habitat potential

Rocky areas are evaluated not only for exposure and structure, but also for real species use, vulnerability, and ecological limitations.

Ruderal and transition areas

Disturbed soils, plateaus, and internal roads reveal how erosion, compacted ground, water retention, and succession influence restoration outcomes.

Monitoring, mapping, and ecological analysis

The Zunzgen project combines practical field work with structured observation and analytical tools.

Drone mapping

Drone-based aerial imagery allows a precise reading of site structure, topography, vegetation patterns, and ecological sectorization.

Wildlife monitoring

Camera traps, direct observations, bird sound recording, and field traces help document the diversity and activity of species across the parcel.

Plant biodiversity assessment

Plant, tree, and flower identification helps track succession, habitat development, and the changing ecological character of the site.

Data analysis

Structured recording and analysis support the interpretation of biodiversity, species abundance, habitat differences, and sector evolution through time.

Why this project matters beyond one site

The restoration of Parcel 1988 demonstrates that ecological restoration must be site-specific, monitored, and capable of adapting when ecological conditions reveal new realities.

Standard measures are not enough

Habitat structures only become ecologically meaningful when their placement, connectivity, and surrounding conditions truly support species use.

Monitoring changes decisions

Continuous observation helps identify when a measure must be improved, relocated, protected, or reinterpreted.

Connectivity is central

Forest links, access routes, hydrology, and wildlife movement must be read together if restoration is to become ecologically functional.

Adaptive logic is transferable

The methods developed in Zunzgen can serve as a model for other degraded landscapes in Baselland and beyond.

A detailed case study is available

The Zunzgen project is also presented in a longer article focused on adaptive restoration, methodology, biodiversity analysis, and the broader implications of this work.
