Federal Inventory of Fens of National Importance

Fens are vestiges of earlier natural and cultural landscapes and are in sharp decline. They are home to highly-adapted symbiotic communities of plants and animals that include a large number of endangered plant and animal species. The scientific fen inventory was conducted from 1987 to 90 by a work group on behalf of the FDHA. Under Art. 18a of Article 18a of the Federal Act of 1 Juli 1966 on the Protection of Nature and Cultural Heritage (NCHA), the Federal Council designates the biotopes of national importance, assesses their situation and sets conservation objectives for them. However, this occurs only after the cantons have been heard. In 1994, the Federal Council implemented the Fen Ordinance with the federal inventory, whose first series contained 728 sites. Its second series with 364 sites followed in 1997, and the third and final series with 71 sites in 1998. Some of the sites were revised in 2001, 2004, 2007, 2017 and 2021. The inventory now contains 1333 Objects.沼泽（fen）是早期自然与人文景观的遗存，其存续现状正急剧恶化。它们是高度适应环境的动植物共生群落的栖息地，其中包含大量濒危动植物物种。1987年至1990年间，受联邦湿地与历史景观协会（FDHA）委托的工作组开展了科学的沼泽地普查。根据1966年7月1日颁布的《自然与文化遗产保护法》（NCHA）第18a条，联邦委员会将指定具有国家重要性的生境，评估其现状并制定相应保护目标，但该流程需先征询各州的意见。1994年，联邦委员会结合本次联邦普查结果出台了《沼泽地保护条例》，其首批名录共收录728处点位。1997年推出第二批名录，收录364处点位；1998年推出第三批也是最后一批名录，收录71处点位。后续分别于2001年、2004年、2007年、2017年及2021年对部分点位进行了修订。目前该普查名录共收录1333条记录。
