Swiss Lynx Face Ongoing Threats Despite Population Recovery

The lynx has made a remarkable comeback in Switzerland over recent decades, successfully re-establishing itself across parts of the Alpine and Jura regions. However, conservation experts warn that the species still faces significant challenges that could threaten its long-term survival.

According to WWF Switzerland, recent studies reveal that road and railway accidents remain the leading cause of death among wild lynx. As transportation networks expand and traffic volumes increase, these majestic predators continue to face serious risks while moving through their natural habitats.

Researchers have also confirmed cases of illegal poaching. While documented incidents already raise concerns, experts believe the true scale of poaching may be much higher due to unreported cases that remain undetected in remote areas.

In addition to human-related threats, scientists have identified congenital heart defects in several lynx populations. Researchers suggest that these rare health problems may be linked to limited genetic diversity within Switzerland’s lynx population, highlighting a growing concern for the species’ future health and resilience.

WWF lynx expert Gabor von Bethlenfalvy emphasized the importance of the lynx within Switzerland’s ecosystem. As a top predator, the lynx helps regulate wildlife populations and contributes to maintaining healthy and stable forest environments.

Today, approximately 360 lynx are believed to live across the cross-border Alpine and Jura regions. Due to its central role in supporting these populations, Switzerland carries a significant responsibility in ensuring the species’ long-term protection.

Conservation organizations are calling for stronger measures, including the creation of connected wildlife corridors, targeted releases to improve genetic diversity, enhanced international cooperation, and continued scientific monitoring. Experts believe these actions are essential to secure a sustainable future for one of Switzerland’s most iconic wild animals.

Swiss Wolf Packs Rise to 43 in 2025.

Switzerland’s wolf population continued its steady expansion in 2025, with wildlife experts confirming the presence of 43 wolf packs across the country. The latest findings, released by the Kora Foundation, highlight the ongoing recovery of one of Europe’s most closely monitored wildlife species.

According to the annual report, researchers identified approximately 350 wolves living in Switzerland during the year. The increase reflects the species’ continued spread into new regions and its successful establishment in several cantons.

A significant milestone was recorded in the canton of Obwalden, where a wolf pack was confirmed for the first time. Another newly established pack was documented in the canton of Neuchâtel, further demonstrating the growing geographic range of wolves within Switzerland.

Researchers also made an important scientific discovery in the canton of Bern. For the first time, a pregnant female wolf from the Central European wolf population was officially recorded in Switzerland. Until now, the vast majority of wolves found in the country have originated from the Alpine wolf population.

Another notable development occurred in the canton of Valais. Wildlife experts documented double reproduction within a single wolf pack for the first time. Two female wolves successfully reproduced during the same breeding season, a rare event that provides valuable insight into wolf behavior and population dynamics.

The growing wolf population continues to attract attention from conservationists, farmers, and policymakers. Supporters view the increase as a success for biodiversity and wildlife conservation, while others raise concerns about the impact on livestock and rural communities.

The Kora Foundation’s findings provide important data for future wildlife management decisions. As wolf numbers continue to rise, authorities are expected to balance conservation goals with measures designed to protect agriculture and maintain coexistence between wildlife and local communities.

The latest report confirms that wolves are becoming an increasingly established part of Switzerland’s natural landscape, marking another significant chapter in the country’s wildlife conservation efforts.

Swiss Insect Species Show Mixed Recovery.

Researchers from several Swiss institutions analyzed records of 811 insect species collected between 1930 and 2021. The study, published in the journal Nature Ecology and Evolution, provides one of the most comprehensive pictures of long-term insect population trends in Switzerland.

The findings show that deadwood beetles have experienced a strong recovery after decades of decline. Their numbers dropped steadily until around 1960 but later stabilized and have now returned to levels similar to those recorded in 1930. Scientists attribute this recovery to improved forest management practices, increased biodiversity protection, and the availability of more deadwood habitats.

Butterflies, however, tell a very different story. Their diversity declined sharply until the 1980s and has failed to recover. Today, Switzerland has approximately 12% fewer butterfly species than it did in 1930. The decline is especially severe in the Central Plateau region, where butterfly diversity has fallen by nearly 29%.

Researchers point to agricultural intensification between 1950 and 1980 as a major factor behind these losses. The widespread use of fertilizers and pesticides, combined with landscape simplification, significantly reduced natural habitats for many insect species.

Climate change has also played a role. Rising temperatures have benefited certain warmth-loving species, particularly deadwood beetles, allowing them to expand their range. Major storms such as Vivian in 1990 and Lothar in 1999 also created large amounts of deadwood, providing valuable habitats for beetle populations.

The study highlights that environmental protection measures introduced since the 1990s have produced positive results, particularly in forest ecosystems. However, researchers warn that stronger and more targeted conservation efforts are still needed to protect vulnerable species such as butterflies.

Experts believe that preserving biodiversity remains essential for maintaining healthy ecosystems, pollination services, and Switzerland’s natural heritage. The findings serve as both a success story for conservation and a reminder that many species still require urgent protection.

Otter Returns to Switzerland After Decades of Absence.

The otter has returned to Switzerland after disappearing for decades, marking a significant milestone for wildlife conservation efforts. However, environmental organisations warn that its long-term survival depends heavily on continued river restoration and habitat protection across the country.

According to conservation groups Pro Natura and Pro Lutra, multiple otter sightings were recorded in January 2026 across different regions of Switzerland, suggesting a slow but steady natural return of the species.

One of the most notable sightings occurred on January 11 in Selzach in the canton of Solothurn, where snow tracks along the River Aare confirmed otter presence for the first time in 91 years. Another sighting followed on January 15 when a wildlife camera captured an otter swimming in the Linth Canal in the canton of Glarus.

Additional reports of otters, including juvenile individuals, have also emerged from several Swiss cantons such as Graubünden, Bern, St Gallen, Ticino, Lucerne, and Zurich, indicating a wider regional presence.

The species disappeared from Switzerland in the late 20th century, with the last confirmed sighting recorded in 1989 at Lake Neuchâtel. Experts attribute its extinction to hunting, river modification, and water pollution, despite legal protections introduced in 1952 and environmental bans implemented in the 1980s.

Conservationists explain that otters have been able to naturally recolonise Switzerland by travelling through river networks connected to the Danube basin via Austria’s Inn region. This ecological corridor has allowed the species to gradually expand back into Swiss waterways.

However, experts warn that the otter’s survival is still uncertain. The species depends heavily on healthy fish populations, yet studies show that two out of three fish species in Switzerland are currently threatened. Environmental groups stress that river renaturation must be expanded significantly to support aquatic biodiversity.

Authorities currently restore less than half of the 50 kilometres of river habitat required annually by law, raising concerns about long-term ecological balance. Without stronger action, conservationists fear that the otter’s return could remain fragile.

World Otter Day, celebrated on the last Wednesday of May, is used globally to raise awareness about otter conservation. In Switzerland, events are also held on May 27, including educational activities at Muzoo La Chaux-de-Fonds and online webinars focusing on otter species and habitat protection.

Blackcap Becomes Switzerland’s Most Common Bird, Overtaking Chaffinch

The blackcap has become the most common bird species in Switzerland, overtaking the chaffinch, according to the 2025 bird monitoring programme by the Swiss Ornithological Institute.

Researchers report that there are now nearly one million breeding pairs of blackcaps across the country. The species has expanded significantly, benefiting from forest growth at higher altitudes and changing environmental conditions.

The study also suggests that more birds are choosing to remain in Europe during winter instead of migrating south, which has contributed to the blackcap’s population increase.

At the same time, chaffinch numbers have declined. Scientists say the reasons for this decrease remain unclear, describing it as puzzling due to the lack of identifiable causes.

Other common species such as sparrows and blackbirds continue to rank among the top ten most widespread birds in Switzerland. However, urban species like the street pigeon do not appear in the top 50.

The monitoring programme involved around 300 staff members from the Swiss Ornithological Institute, who dedicated more than 3,000 hours to collecting data on breeding bird populations across the country.

Experts say the findings highlight how climate change, habitat shifts, and migration behavior are reshaping Switzerland’s bird populations.

Preventive Culling Slows Wolf Population Growth in Switzerland

Preventive culling measures have successfully slowed the growth of the wolf population in Switzerland, according to a federal assessment covering regulatory actions since 2023.

The Federal Office for the Environment (FOEN) reported that more than 220 wolves have been killed across three regulatory phases, including animals removed before causing any recorded livestock damage.

During the most recent period from September 2025 to January 2026, authorities culled 77 wolves. In the previous 2024/2025 phase, 92 wolves were removed, while the initial shorter phase recorded 55. In all cases, the number of wolves shot remained below the maximum quotas authorized by federal authorities.

FOEN data shows that during the latest cycle, 76 wolves were removed through preventive measures and one following confirmed livestock damage. The government had approved the culling of approximately 115 wolves for that period.

Authorities state that the policy aims to manage wolf numbers in regions where livestock farming is affected while maintaining ecological balance. The approach reflects Switzerland’s effort to balance wildlife conservation with agricultural protection.

The federal government concludes that regulated culling has contributed to stabilizing wolf population growth, although debates continue over long-term wildlife management strategies and conservation ethics.
