The Guggelesgraben , formerly called Neuberggraben , is a creek almost a kilometer long in Lower Franconia , which flows into the Steinbach from the left when coming from the north .

geography

course

The Guggelesgraben is being built in the southwestern Maindreieck on the Marktheidenfelder Platte in the Steinbachtal district of Würzburg on the southwest slope of the Nikolausberg at an altitude of about 304  m above sea level. NN on the south side of the Upper Steinbachweg .

It initially flows almost seven hundred meters southwards through a narrow, wooded blade, the slopes of which are built on with houses, then disappears into the subsoil and finally flows into the southern edge of Steinbachtal piped at a height of less than 220  m above sea level. NN from the left into the Steinbach flowing from the west .

Catchment area

It covers about 0.8 km² and borders on the main tributary Kühbach in the north , while in the west in the Annaschlucht and in the east in the Geigersgraben , both of which are a bit smaller, two more or less constant neighboring short watercourses also run south to the Steinbach . The with about 355  m above sea level. NN highest point is on the northeast corner of the catchment area on the summit of Nikolausberg .

environment and nature

The Guggelesgraben has been a natural monument since 1939 . In 1983 the reserve was limited to about five hectares.

The hornbeam is the dominant tree species in the gorge . There are old oaks in the northern area of ​​the blade . The field and Norway maple , the common beech , the pedunculate oak , the elm and the chestnut also thrive in the shady, up to seventy meters wide valley gully. The herb layer , in which ivy, yellow dead nettle and cranesbill predominate, cannot develop as well because of the steep slope and the resulting strong shade.

The old, hollow and fallen trees in the reserve create a suitable environment for numerous species of birds and insects. Small mammals find good shelter in the privet and sloe hedges there.

Also worth seeing on the gorge are the limestone cliffs that lie in front of them , which are valuable both in terms of geomorphology and in terms of their ecological role.
