If you have attended our latest AGMs you have often heard talk about the Purple Bladderwort (Utricularia Purpurea<\/b><\/i>)<\/b> <\/b>in Black Lake. It is a carnivorous plant found in many places in the Eastern part of North America, but only in a very few lakes in the Laurentians. When abundant it can be bothersome but it is otherwise harmless.<\/p>\n
This 2,5\u00a0 minute underwater video was done in the far east section of Black Lake last summer. The author is none other than Dr. Richard Carignan,<\/a> Quebec’s foremost lake expert. He is also an active member of the GRIL (Group for Interuniversity Research in Limnology and Aquatic Environment<\/a>)<\/p>\n He has identified in French the plants seen in the video. I am providing you here with the appropriate English names. First, in order of appearance, is\u00a0 la (Vallisn\u00e9rie am\u00e9ricaine, (Vallisneria Americana<\/span><\/strong><\/em>),\u00a0 Bras\u00e9nie de Schreber,\u00a0 (Schreber Watershield<\/strong><\/em>), Potamot \u00e0 large feuilles, (Large-Leaved Pondweed<\/strong><\/em>)\u00a0 then lots of Purple Bladderwort<\/strong><\/em>. Finally,\u00a0 a composite of the latter, plus vallisn\u00e9rie am\u00e9ricaine (Tapegrass)<\/em><\/strong> and some potamot \u00e9merg\u00e9 (Ribbonleaf Pondweed<\/strong><\/em>). All of these plants, except the Purple Bladderwort, are common in all our lakes.<\/p>\n <\/p>\n
