Natura 2000 site ROSCI0099 Pike Lake -Sic-Puini-Bonţida is very heterogeneous in terms of landscape, including wetland ecosystems, like natural lakes and ponds, but also thickets, wt and dry meadows and woodlands. It was designated in 2007 (1964/2007 O.M amended and supplemented by O.M. 2387/2011) to help the conservation of nine types of natural habitats included in Annex I of the Habitats Directive, five of which being priority habitats for conservation. Field research carried out by the custodians of the site revealed the presence of another two types of Natura 2000 habitats: 6210 Natural dry grasslands and facies with bushes on limestone Festuco Brometalia and 62C0* Ponto-Sarmatian steppes, plus two national habitats: R3122 Ponto-Pannonian hedges with blackthorn Prunus spinosa and hawthorn Crataegus monogyna and R5309 Danubian communities with Phragmites australis and Schoenoplectus lacustris. This site has also been designated for the conservation of two species of toads, the Yellow-bellied toad (Bombina variegata) and Red-bellied toad (B. bombina), two species of beetles, the well-known stag beetle (Lucanus cervus) and Bolbelasmus unicornis, and three plant species: Red Viper's Bugloss Echium russicum, Tatarian Colewort Crambe tataria and Serratula lycopifolia. Overall this site is inhabited by over 670 plant species, including endemic species and subspecies like Astragalus exscapus ssp. transsilvanicus and Centaurea ruthenica, which has only two known populations throughout the European Union, Bulbocodium versicolor, Serratula wolffii and Iris pontica, all being endangered species both in Romania and the European Union. Woodland ecosystems are fragmented, patchy distributed and with low connectivity. The main tree species are hornbeam (Carpinus betulus) and sessile oak (Quercus petraea).
The site has an area of 3,798 ha and consists of 10 areas - polygons distinct, characterized by limits sinuous, often without physical landmarks on the ground, situated in the administrative territory of the municipalities Bonţida, Căianu, Fizeşu Gherlii, jacket, Jucu, Palatca, Sic, Taga and Gherla.
The site ROSCI0099 is located in northwest Transylvania Plain, about 50 km from Cluj-Napoca and is accessible using the county road 109C Gherla - Taga - Cămăraşu either from Gherla (DN1C) or from Cămăraşu (DN16 Cluj-Napoca - Reghin)
