“…The natural forage of wild animals rich in herbs, minerals and other components has a favourable effect on the nutritional and functional value of meat [14]. Moreover, beaver meat has been recognized as a perfect raw material [15], free from growth stimulators, antibiotics, hormones and other additives [5], with good technological properties [16]. Although the market for game products in recent years is very restricted, and dependent on the hunting season and the culling quotas, wild meat provides a niche in the contemporary food market [17][18][19].…”

“…Extractive goods from beavers include food, materials (castoreum for the perfume industry and pelts), and medicinal resources (castoreum for the natural products industry). Annual harvest levels vary between 1 and 5% in North America, 12% in Europe, and 2% in Russia, which equates to approximately 580000 beavers killed annually in total (Belova et al 2015, White et al 2015, Florek et al 2017, Borisov & Baranov 2018). The large harvest percentage in Europe is influenced by numbers killed in Finland, where North American beavers occur as an invasive species close to, and in certain areas sympatrically with, European beavers (Parker et al 2012, Alakoski et al 2019).…”

We aimed to recognise beaver‐produced ecosystem services and quantify their theoretical value for the entire Northern Hemisphere. Activity of the Eurasian beaver Castor fiber and the North American beaver Castor canadensis in the landscape provides ecosystem services and disservices. Services produced by beaver activity include water purification, moderation of extreme events, habitat and biodiversity provision, nutrient cycling, greenhouse gas sequestration, recreational hunting and fishing, water supply, and non‐consumptive recreation. Beaver‐produced services have not been compiled, analysed, or quantified previously. Each service we evaluated is worth millions to hundreds of millions of US dollars (USD) annually. Habitat and biodiversity provision (133 million USD), along with greenhouse gas sequestration (75 million USD), are particularly valuable services in absolute terms, while non‐consumptive recreation (167 USD ha−1) and habitat and biodiversity provision (133 USD ha−1) have the largest annual per‐hectare values. Our results can be used to broaden decision‐making and management perspectives, as we offer value estimates to wildlife managers and municipality planners for assessing local site‐specific beaver wetland values and the opportunities for their realisation. Implementing Payments for Ecosystem Services schemes offer a concrete way for societies to benefit from beaver‐produced services while concurrently compensating beaver‐produced losses accrued to landowners. Building such schemes offer long‐term realisation of ecosystem services and damage mitigation. This would lead to increased societal well‐being and increased conservation interest and efforts.

“…However, surveillance study on Trichinella species in red foxes indicates T. britovi as predominant species for this host and region, the same as in Slovakia (Hurnikova and Dubinsky, 2009). The origin of Trichinella infection in beavers is unknown since these animals are typical herbivores (Florek et al, 2017; Gorczyca et al, 2018). In spite of this, in hard conditions animals for supplementation of protein or mineral deficits may feed on things they don't usually include in their diet.…”

“…In the past, they were very intensively hunted for fur and castoreum. In Poland, beaver meat was traditionally consumed by hunters and treated as a delicacy (Florek et al, 2017). In the Middle Ages, the beaver was considered as one of the most common animal species in Poland.…”

“…Therefore, in some places, the number of free living beavers has to be reduced (Misiukiewicz et al, 2018). The meat of hunted animals again becomes an object of consumption (Florek et al, 2017). In 2015, after the publication on the first findings of Trichinella britovi in beavers in Latvia, we decided to start research on this uncommon game animal (Seglina et al, 2015).…”

BackgroundThis is the first report of the finding of Trichinella spiralis in beaver meat (Castor fiber) in Poland and Europe. In Poland, the beaver is a strictly protected animal species, except the few regions where high population density leads to economic losses. In these areas, the reduction culling of the animals was introduced. This uncommon hunting game animal is consumed and treated as a delicacy by hunters. However, currently, there is a lack of knowledge on possible risk factors for humans associated with the consumption of beaver meat. This paper presents the result of the study on the occurrence of nematodes of the genus Trichinella in beavers.MethodsIn total, 69 beavers were examined for the presence of Trichinella spp. The 50g samples were taken from each animal and digested separately, according to a procedure based on the EU reference method. The larva DNA was examined by PCR and sequencing.ResultsOne of the 69 examined beavers was infected. Only one Trichinella larva was detected by the digestion method. The result of PCR confirms the presence of T. spiralis in beaver meat.ConclusionsThis case further confirms the ability of these typical herbivores to be infected with Trichinella spp. This is the second confirmed case of Trichinella spp. infection in beavers in Europe and the first of T. spiralis.
