  Dogs mess up trails and forests
  Off-Leash Dogs Degrading Trails 
  Hiking with your dog can seem like a natural fit, but parks managers say too many people are letting their dogs run wild in the wild. As KUOW's Ann Dornfeld reports, off-leash dogs are taking a toll on the region's trails. This story hits close to home for us as we keep seeing garlic mustard moving from trails into the forest in areas that are frequently used by off-leash dogs.

  Food for Thought on Nature

• Olympic National Park growing nature's 'defenders' for Elwha River restoration. This experiment in large scale restoration includes a plan for keeping invasive plants at bay. This is great news because this issue is all too often left until the problem is already there. Prevention is much cheaper and it sounds like they will be making every effort to stay ahead of the weeds. It will be worth watching to see what works and what doesn’t.
• Restoration project helps heal the ecosystem: The University of Washington joins Pierce in a collaboration to restore the Oak Prairie ecosystem through academics and community outreach. This project at Pierce College is working to restore a piece of the prairie habitat that used to be much more common in Pierce County and other parts of south Puget Sound. The main obstacle is, not surprisingly, Scotch broom.
• Killer weed invades farms, grazing lands, and national parks. O.K. this story is from Kenya, but I couldn’t resist the dramatic headline. The weed in question is from Central America, so not very likely to be a threat in our colder climate. Still, it is an interesting look at how similar the issues and impacts are globally with noxious weeds.
• English holly and English laurel – uninvited guests. An article about English laurel and holly from Mukilteo Washington.
• Weeds lurk in package of wildflower seeds. This article talks about wildflower seed mixes and how some of these packets may contain noxious weeds. A few good points highlighted here are: not all species are listed on wildflower seed packets, a ‘native’ seed mixture may not be native to where you are actually planting the seed mix and that planting a trial section in your yard first is a good way to see what species are in the packet of seed you purchased. The studies on this were done at the University of Washington.
• Boat stickers proposed to fight spread of invasives. This article talks about an effort in Minnesota to have boats use stickers (red or green) to denote if they have been in clean or invaded lakes. The idea is that boats that are used in uninvaded or ‘clean’ lakes would have a green sticker and can go in other clean lakes while boats with red stickers would boat in invaded lakes. For a boat with a red sticker to go into a clean or green sticker lake, the boat would need to be inspected to make sure it is not transporting any invasive species. It’s an interesting proposed program and is one to watch to see if they can make it practical to implement.
• Winter-long, Officials Prep to Fight Invasive Species. This second Minnesota article on invasive species mentions a few we are familiar with here (parrotfeather, purple loosestrife and Eurasian watermilfoil) and how some of the aquatics may not be growing as much this winter due to the large amount of snow they have (less light is penetrating the ice for the aquatic invasives).
• Building an outdoor classroom in McKinleyville: Land trust, Dow's Prairie effort explores seasonal wetland for education. In McKinleyville, California school children are taking part in a restoration project called the Dow’s Prairie Schoolyard Habitat Program. The program, funded by grants, teaches the school children all about a wetland that they are working to help restore. Restoration work includes removing invasive plants we deal with here including Scotch broom and blackberry. Involving schools that are close to restoration projects may be something many of your are doing already or could be something to try in the future.
• Effort by Legislature to stop invasive plants shrivels. News update on Texas and invasive aquatic plant species: it looks like the white list effort in Texas—creating a white list of aquatic plants (vs. a black list approach) is being dropped.
• Grazing Arizona: Goats vs. Mesa weeds, Round 2. This article talks about goats being used in Arizona to control weeds including saltcedar. There is a nice video here if you are interested in watching the goats in action, along with how and why they are being used in this area.

• "Worst ever" fireweed destroying paddocks. This story about a toxic pasture weed in New South Wales, Australia sounds very familiar to those of us fighting with tansy ragwort. Their plant pest called fireweed (Senecio madagascariensis) is in the same genus as tansy ragwort (Senecio jacobaea) and is toxic to livestock in the same ways. You could call it tansy ragwort’s South African cousin. Note that, although it’s called fireweed, this plant is completely different from our native plant also called fireweed (Epilobium angustifolium). Interestingly, Senecio madagascariensis is a noxious weed in Hawaii as well as Australia, although it prefers a more tropical climate, so it’s not likely be a problem here.
