Trekanten (Stockholm)

Leading up to Nybohov on the southern side of the lake is a fault bluff with pines and deciduous trees, including hazel.

On the eastern shore is a bathe next to the Liljeholmen metro station, a bus terminal, the light rail Tvärbanan, newly added flats, and some older buildings.

[4] In late summer, phytoplankton stock is dominated by green algae paired equal levels of diatoms, cyanobacteria, and a species of eutroph carapace flagellate (Ceratium hirundinella).

Several of the blue green algae present in the lake are potentially poisonous and, notwithstanding non-alarming levels, therefore carefully monitored near the bathe.

[5] An inventory of lake bed fauna in 1997 produced a list of only 29 species/taxa including most common species, mostly freshwater gastropods, fireflies, and leeches but no beetles.

[5] In early summer the lake is home to a number of birds including thrush nightingale, common chaffinch, garden warbler, and blackcap.
