The spring breeding season for Wisconsin turtle species runs approximately May through July and WDNR biologists are asking citizens to submit their observations of where turtles are crossing roads, as well as where they’re seeing turtle that have been killed. [Read more…]
I’ve been “managing” garlic mustard since April and I am amazed at where I am finding it. It’s showing up in places I’ve never seen it before and I am getting just a little discouraged. Now that the ground is getting dried out, it is more difficult to get past the s-shape of the root to dig them out. And the foliage of the other plants is getting high enough that I can’t see all the seedlings still popping up everywhere! I have a feeling the mild 2015-16 winter had something to do with its extraordinary propagation this year.
Last year Martine and Hale of Bucknell University, Lewisburg, Pennsylvania published a paper introducing evidence toward the negative effects of the invasive plant garlic mustard (Alliaria petiolata) on native mycorrhizal associations. The disruption occurs because garlic mustard produces anti-fungal compounds which not only hamper formation of new associations between native plants and mycorrhizae, but also diminishes the effectiveness of existing connections. Testing shows that native plant species produce less biomass as a result of this loss in the fungi network which means there is diminished carbon storage and indirectly effects things like seedling growth and flowering frequency. This parasitism disruption has the potential to impact biodiversity in far reaching ways. So manage that garlic mustard with a vengeance!

Last week during the Larry Meiller Garden Talk (Wisconsin Public Radio) program, a woman called in to ask what she could do to get rid of Scilla aka Siberian Squill (Scilla siberica). This invasive non-native plant was taking over her lawn and was now moving into her woods. My ears perked up immediately since I, too, have a problem with this nasty non-native.
I don’t know where it came from — probably the birds — but it’s been a “growing” problem for me for several years. It started with one tiny plant in one of my native plant woodlands and has since moved out to the lawn and a second woodland and into the prairie. I’ve tried digging out the bulbs, but they go so deep into the ground, they’re impossible to remove. [Read more…]
