Belhavel Lough (Irish: Claonloch, meaning 'crooked lake')[3] is a freshwater lake in the northwest of Ireland. It is located in north County Leitrim near the village of Killarga.
Geography and hydrology
[edit]Belhavel Lough is about 2 kilometres (1.2 mi) south of Killarga and 5 km (3.1 mi) north of Drumkeeran.[1] It covers an area of 1.01 km2 (0.4 sq mi).[2] The lake drains east into the Diffagher River, which eventually reaches Lough Allen.[1]
Ecology
[edit]The water quality was reported to be satisfactory c. 2001 – c. 2003 with a mesotrophic rating,[4][n 1] but had a "poor" ecological status c. 2007 – c. 2009 indicating pollution,[6] though Zebra mussel infestation was not reported.[7] The ecology of Belhavel Lough, and other county waterways, is threatened by curly waterweed, zebra mussel, and freshwater clam invasive species.[8][9]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
