The paper analyzes the problem of stagnation in the creation of new national parks in Poland, identifying key barriers and proposing solutions. The background to the study refers to the role of national parks in nature conservation, but at the same time highlights the problem of the limited development of the park network in Poland, which remains at 1.05% of the country’s area—well below the EU average. The main obstacles identified by the author are the resistance of local governments due to the reduction in forest tax revenues and the differences in salaries between employees of national parks and state forests. Research methods included legal and economic analysis and a review of the literature on national park management. The results indicate that the problem can be solved by adequate financial compensation to local communities and the introduction of a co-management model that integrates the interests of local governments and parks. The article suggests that a change in the approach of the government administration and a more participatory management model can help to break the stagnation and increase the number of national parks, which is relevant not only for Poland but also for other countries struggling with similar challenges.
