It has also been found to be common in temperate regions in North America near rivers and in Europe within lowland areas near the Baltic sea.

[2] T. megapolitana has been found growing in wet horizontal willow steps, roots, and fallen branches within ditches that contain clay.

[1] It was found in the northern part of Estonia within moist and shady forest near coastal calcareous cliffs and found in Pine forests that have been exposed to calcareous dust from nearby quarries on the decaying tree stumps of Salix caprea.

[4] In Germany and Poland the species was found to be in calcareous marshy meadows, hayfield, and on slopes of marl.

[3] In eastern North America, T. megapolitana is found in river bottoms swamps, moist and shaded soil or humus, and rarely at the base of trees.

Both Siberia and the Netherlands share similar habitats for T. megapolitana in which the species is found on mud-covered willows in forests along rivers.

[3] Timmia has been found to often be covered with silt and is restricted to a part of the Biesbosch with small scale tidal divides.

It has been found near tidal floods along with algae of the genus Vaucheria catching silt and allowing vascular plants to germinate.

When fertilization takes place, a zygote is produced and this eventually develops into a sporophyte onto the gametophyte plant (which is the parent).
