Podlesí, Nature reserve in Býkovice, Czech Republic.

Podlesí is a 9.6-hectare reserve of peat and wet meadows south of Malý Blaník (580 m) and north of Býkovice, in the Blaník Protected Landscape Area. An asphalt road to Býkovice divides it in two: one part holds the Velký and Malý Býkovický rybník ponds, the other a peat bog with artificial pools.

The area was originally mown repeatedly as a source of bedding, and a system of drainage furrows was dug to regulate water. On 28 April 1993 the Administration of CHKO Blaník declared the 9.6-hectare reserve. Both ponds formerly served as carp fry ponds, and a concrete handling platform at the edge of Velký Býkovický rybník recalls that period.

The two adjacent ponds, Velký and Malý Býkovický, are nicknamed Jordán and Jordánek by locals. The name Podlesí refers to the wet meadow lying below the forested slope of Malý Blaník. The meadow was traditionally mown for bedding, and the drainage furrows cut for that purpose still cross it.

An asphalt road to Býkovice cuts the reserve into two parts: the peat bog with artificial pools on one side, the two Býkovice ponds on the other. The terrain is flat to gently sloping at 474–486 m, crossed by the Býkovický potok, which rises in the upper part of the reserve. A concrete handling platform for fishermen remains at the edge of Velký Býkovický rybník.

The two adjacent ponds are nicknamed Jordán and Jordánek by locals. A concrete manipulation platform on the edge of Velký Býkovický rybník recalls the era of intensive carp-fry farming, when ponds were limed and fertilised with superphosphate, saltpetre and farmyard manure.
