Conquer the Lupine in the Giant Mountains! Your Adventure Will Benefit Nature

Lupine multifoliate, often referred to simply as lupine, originates from North America. It starts blooming in June, and the many flowers it produces lead to a significant number of seeds that germinate easily. When fully grown, these plants are robust and can create extensive areas of growth. They work together with beneficial bacteria to enhance nitrogen levels in the soil and adjust the nutrient balance in the soil to be more favorable for other plants like nettles or sorrel. In the Czech Republic, however, lupine is identified as a harmful invasive species that disrupts our ecosystems. Invasive species are known for their ability to spread rapidly. The lupine follows a highly efficient survival strategy, producing a large quantity of seeds and forming thick patches of vegetation. In this area, it faces no natural predators.
Sadly, lupine can also be found in the meadows of the Krkonoše Mountains, where it is slowly taking over native meadow plants. This poses a significant threat to these meadows. Research has shown that the presence of lupine is increasing in the Krkonoše region. As a highly invasive species, it harms native plants in the Krkonoše. Unfortunately, the KRNAP Administration cannot always manage to remove lupine promptly where it has spread. Therefore, park rangers are reaching out for assistance from the public, meadow owners, and farmers. Mowing early will help prevent the further spread of lupine. It is essential to cut dandelions when they start to bloom to stop them from producing seeds. The KRNAP administration would also appreciate any reports of lupine sightings and other invasive plants in the Krkonoše Mountains. A if you see blooming lupine during your hikes in the mountains, please feel free to pick it as it can benefit the local flora (just be careful not to pick lupine that has already flowered and has ripe seeds, so you don’t contribute to its spread).

Protecting Nature in Krkonoše National Park: How You Can Help

The Krkonoše National Park, established on May 17, 1963, is renowned for its remarkable natural beauty and diverse landscapes. To preserve this unique environment, we encourage all visitors to act respectfully toward the plants, animals, and surroundings.

About Lupine in the Park

Lupine (commonly known as lupine) is an invasive plant species originally from North America. It poses a serious threat to the ecosystems of the Giant Mountains by producing large populations that overwhelm native grassland species and disrupt soil nutrient levels. This negatively affects the native plants and overall balance of the area.

How You Can Help

• Pick flowering lupine to take home for a vase, helping reduce its spread.

• Notify park managers if you spot lupine or other invasive species.

• Cut lupine before it flowers to prevent it from producing seeds and spreading further.

Enjoying the Natural Meadows

While walking along farm trails, you might encounter notable meadow species such as arnica, orchids, gentians, and bentgrass. These native plants contribute to the park’s biodiversity and beauty.

Our Guidelines for Visitors

Although there are no specific restrictions regarding lupine, we ask visitors to be as considerate as possible toward all plants, animals, and the environment. We have prepared ten suggestions for holiday visitors on how to interact respectfully in nature and national parks. These guidelines aim to protect the environment and ensure everyone can enjoy the natural landscape responsibly.
